In the duty room on the first floor, the ghosts and monitoring system No. 663 were heartbroken, but Bai Shuangxing himself, the culprit, knew nothing about it.

She was in a good mood and yawned lazily. After having a "friendly exchange" with the ghosts in the dormitory building, she returned to the dormitory on the fifth floor.

Shen Chan, who was in charge of pulling the switch, still couldn't get enough of it: "It's a pity that 663 canceled the hidden mission, otherwise we could really get rich overnight."

Jiang Mian followed her around for a whole day, and now she was exhausted. After being patted on the head by Bai Shuangxing, she went to bed early.

The other girls had already returned to the dormitory, and when they saw that they finally came back, they poked their heads out of the bed.

Unknowingly, it seemed that as long as Bai Shuangxing was by his side, the students would feel more at ease.

"The dormitory building is currently safe and nothing will happen."

Bai Shuangxing smiled and said softly, "You guys have a good rest, there is still class tomorrow."

Chen Miaojia was curious: "Did you find out anything just now?"

To be honest, until now, she has been shocked by Baishuang's various operations.

When normal people encounter ghosts, they will definitely run around in panic. As long as they survive, everything will be fine. How can they have time to think about killing.

As a result, Bai Shuangxing not only succeeded in countering it, but also turned the ghosts in the building into her... How should put it, a question box that answers all questions?

Bai Shuangxing answered honestly: "The ghosts don't know why they appear here. They don't have much memory of their lives, and they only know to kill people according to school rules."

She said and changed the subject: "You have a good impression of Mr. Qin, what about the principal? What kind of person is he?"

There was a moment of silence in the bedroom.

"headmaster"

Chen Miaojia thought for a few seconds: "Ordinary students should have nothing to do with the principal, right?"

This sentence is true.

The principal is not like the teacher who can get along with the students day and night.For the vast majority of high school students, the position of "principal" is like the sun out of reach in the sky.

The sun shines in all directions, and everyone can see it from a distance, but in the final analysis, no one can really get close to it.

"The principal has served in Xinghua No. 1 Middle School for a long time."

Girl Qi Liuhai whispered: "He usually looks very kind. If a student greets him, the principal will definitely respond with a smile—so we have a good impression of him."

Shen Chan raised her eyebrows: "Does he not have any bad rumors?"

"No."

Another girl shook her head: "If he really did something bad, once it gets out, he won't be able to be the principal like he is now."

"Then," Bai Shuangxing said, "where's the principal's office? Has anyone gone in?"

The two girls except Chen Miaojia looked at each other and shook their heads in unison.

For this result, Baishuangxing was not surprised.

"What do you ask the principal's office for?"

Girl Qi Liuhai thought for a while, then turned her head suddenly: "What I want to say...ah, by the way, has Chen Miaojia been there once?"

When Chen Miaojia's name was called, her expression froze slightly.

Bai Shuangxing also looked at her.

"Been there."

Chen Miaojia's voice was a bit muffled: "What's wrong?"

Bai Shuangxing went straight to the point: "Do you think there is anything unusual there? For example, the decoration is weird, or it makes you feel spooky?"

Before that, she asked all the ghosts that could be found in the dormitory building.

Some ghosts have completely lost their minds, and some can barely communicate. When asked about the principal, they all said that they didn't know what he was like.

But when it came to the principal's office, many ghosts showed expressions of fear, like the girl shed blood and tears, claiming that there was an unapproachable aura.

Bai Shuangxing felt strange at the time, and continued to question, but they only said that they didn't know.

What is it that can make ghosts so fearful...?

Later, when she returned to the dormitory, she asked Jiang Mian for her opinion.

The girl thought about it for a while, and told her seriously: ghosts are formed by the condensation of resentment, and rarely produce emotions similar to "fear". If there is really something that makes them dare not approach——

The greatest possibility is that there is a more powerful and terrifying ghost hiding there.

While thinking back, Bai Shuangxing waited for Chen Miaojia's reply.

"The decoration in the principal's office is normal, in an ordinary office style."

Any clue could be the key to breaking the situation, Chen Miaojia did not hide it: "But... its location is very special."

Baishuangxing: "Location?"

"Almost all the teachers' offices are concentrated at the end of the corridor on the left side of the teaching building; while the academic affairs office and the secretarial office are in the administrative building."

Chen Miaojia said: "There is only the principal's office, which is built separately on the right side of the first floor of the teaching building."

She thought for a while and continued, "Next to the principal's office are the utility room and the reference room. Usually no one goes in - the principal has to deal with school affairs every day, so he must be in constant contact with other teachers, right? Why do you have to stay in the office?"That kind of place?"

It is indeed strange.

Bai Shuangxing listened quietly, nodding slightly.

"I said to myself at the time, saying that the corridor is so quiet."

Chen Miaojia said: "I didn't expect the principal to hear it, and he even explained that he likes a quiet place."

Shen Chan frowned, and had a bad premonition in her heart: "To avoid everyone...he won't be doing something shady, right?"

"do not know."

Chen Miaojia shook her head: "I didn't feel anything wrong after I went in, but it was a little bit cold—there was a big tree outside the office, and the sun was covered by the shade."

She couldn't provide any more clues, so Bai Shuangxing nodded, and changed the subject: "Speaking of this matter... May I take the liberty to ask, why did you go to the principal's office?"

Chen Miaojia's expression froze again.

She obviously didn't want to answer, but she was helpless: "...Because of my mother."

While talking, Chen Miaojia's tone became colder: "My mother came to decorate the dormitory, but she quarreled with me and went crazy in the dormitory. It was useless for Teacher Qin to persuade her. Later, there was no other way, so I found the principal."

Bai Shuang's heart moved: "How did the principal solve it?"

"How else can it be solved?"

Chen Miaojia shrugged: "It's the adult's words, calm down, the child is not sensible, don't bother with her - then let me apologize to my mother."

After she finished speaking, she muttered, "Teacher Qin wouldn't do that."

It seems that she really likes Qin Mengdie.

Bai Shuang pushed the boat smoothly: "What did Teacher Qin say?"

Sitting on the bed, Chen Miaojia thought of something, raised her eyebrows and raised the corners of her mouth, with a somewhat smug look: "She said that it was unreasonable for my mother to vent her anger on me because of my younger brother. Please don't be too sad."

Bai Shuangxing also smiled.

"Thank you. One last question."

She was thinking about something quietly, with a faint light in her eyes: "The disciplinary committee member was bullied by the students in the class, can you tell me the specific situation at that time?"

"Well……"

Chen Miaojia rolled her eyes: "It's the tricks that everyone knows - isolating him collectively, laughing at him, stuffing garbage into his desk and so on. Is there anything strange about this?"

Bai Shuangxing shook his head.

She didn't speak, only the light in her eyes became more intense, she leaned against the desk, and curled the corners of her mouth.

From this point of view, her idea should be correct.

The next thing to find out...is the secret in the principal's office.

After the lights-out time stipulated by the dormitory building, no student can leave the dormitory.

Unable to move at night, Bai Shuangxing took the opportunity to sleep well.

When the alarm clock rang the next day, the sky outside the window was not yet fully lit. have to say that the time for high school students to wake up is really short.

Jiang Mian obediently woke up on time, but it was Shen Chan, the sister who showed every kind of reluctance——

She and Bai Shuangxing are both college students, and they haven't gotten up so early for a long time.

When came to the classroom and finished morning self-study in a sleepy and exhausted state, it was time to go to the cafeteria for breakfast.

Bai Shuangxing and Shen Chan looked at each other.

They have more important things to do than eat breakfast.

——It is said that hearing is believing, but seeing is believing.

Instead of asking others about the anomalies in the principal's office, it's better to enter it in person and see what tricks it hides.

Chen Miaojia told them the address of the principal's office, which is at the end of the first floor of the second teaching building.

Time was running out, so taking advantage of the tens of minutes of breakfast, they took Jiang Mian with them, and the two of them and one ghost quickly headed to their destination.

"If we go in later and find that the principal is still in the office, I'll make up an excuse to lure him away."

Walking in the corridor of the teaching building, Shen Chan whispered, "I hope he's gone to have breakfast... Hey, Mianmian, what's wrong with you?"

Jiang Mian followed them, with a serious expression, and pursed her lips.

Bai Shuangxing reacted: "You also feel the 'oppressive force' that those ghosts said?"

"……Ok."

Jiang Mian nodded and added hesitantly, "I think it's very dangerous."

The principal's office is located at the end of the corridor. As Chen Miaojia said, it is too quiet here.

Outside the window are rows of verdant trees, which block the very little light. Looking around, there are black reflections of branches and leaves everywhere.

It is locust tree.

... The legendary ghost in the tree that condenses Yin energy.

Before coming to the office, Bai Shuangxing raised his hand and knocked on the door.

No one responded.

She glanced at Shen Chan, pressed the doorknob hard with her hand.

With a soft creak, the door opened.

There was no one in the house.

Bai Shuang walked lightly, walked into the room, followed by Shen Chan and Jiang Mian, and locked the door again.

The decoration style in the principal's office is very simple, without any fancy decorations.

The area here is small, with a desk, an office chair, and a bookcase neatly arranged, and there is a long sofa for meeting guests near the door.

Can't see any problem at all.

——The premise is, if Jiang Mian's complexion doesn't get worse.

Bai Shuangxing noticed the girl's change, and said softly: "If Mianmian is really uncomfortable, go outside and wait for us, okay?"

Jiang Mian shook his head: "I'm fine."

She blinked: "I don't feel uncomfortable...just a little scared."

Jiang Mian herself is the ultimate ghost in a white night challenge. She is stronger than ordinary ghosts and can scare her...

Bai Shuangxing's eyes darkened: "Can you feel where that breath came from?"

Jiang Mian nodded seriously: "I'll try."

She was concentrating on finding the source of the breath, while Bai Shuangxing and Shen Chan seized the time to explore in the principal's office.

There are two bookcases, one of which is full of heavy books, and the other may be newly bought recently, which is a little empty, with only a dozen books on pedagogy.

Shen Chan searched the bookcase, while Bai Shuangxing went straight to the desk.

The table was clean and tidy, and there were several documents in front of the computer. Bai Shuang glanced roughly, and it was a very common teaching work report.

She moved quickly, opening the drawers under the table one by one.

In the white night challenge, the challengers will definitely be provided with the necessary clues.

Since both humans and ghosts feel that something is wrong in the principal's office, there must be key information hidden here.

Folders, portfolios, some envelopes, a very old book—

Suddenly, Bai Shuang's actions stopped.

Opening the old and yellowed book, one of the pages contained two pieces of letter paper.

The letter paper had been folded, and the handwriting on the paper was badly written.

The first reads:

"Just set it on October 10th? The right time, place and people are right, this time it will definitely be a success."

The font of the second one is more messy:

"Fuck, she seems to have found out. Has that woman been investigating our affairs? She won't meddle in her own business, will she?

The 10th is coming soon... This matter must not be known to others!How about we find a chance?"

it is as expected.

The scattered pieces in his heart gradually pieced together, Bai Shuangxing took a deep breath, and opened his mouth: "Shen Chan, Mian Mian, I found it."

Shen Chan was taken aback for a moment, and walked over quickly.

"October 10th."

Shen Chan saw the date at a glance: "It's the time marked on Teacher Qin's calendar."

"Ok."

Bai Shuangxing nodded: "From the note, the principal and someone planned to do something on October 10th, but Teacher Qin found out in advance. The word 'nosy' was used on the paper, indicating that the matter itself had nothing to do with Qin.It doesn't matter to the teacher."

"And the phrase 'find a chance'—"

Shen Chan frowned, feeling inexplicably cold in her heart: "They want...to kill Qin Mengdie?"

She thought of something, and suddenly realized: "So the ghost with the deepest resentment in this white night is Qin Mengdie who was killed by the principal?!"

"Probably yes."

Bai Shuangxing lowered his eyelashes, and said softly: "And... about the meaning of the school rules, I may have figured it out."

Shen Chan is like a well-behaved elementary school student, her eyes are shining brightly, she looks at her without blinking.

Rubbing the letter paper in his hand, Bai Shuangxing said, "Do you still remember the joke I made when I saw the school rules for the first time?"

Of course, Shen Chan did not forget: "You have changed the description of the phenomenon in daily life, and expressed it in a form similar to school rules, and it still looks good."

"The combination and arrangement of adding oil and vinegar between words can often form different effects."

Bai Shuangxing was thoughtful: "If you want to explore the truth, you only need to peel off the descriptions of gods and ghosts, and you can see the essence."

Jiang Mian tilted his head, showing a blank expression.

Bai Shuangxing smiled.

"For example, Chen Miaojia said last night that her mother scolded her when she came to the dormitory, right?"

She said: "Think again, what have we seen in the dormitory building?"

Shen Chan was startled.

She has always been quick-witted and quickly gave the correct answer: "We have encountered a monster shaped like a mouth!"

Looking back now, the monster was still saying something vaguely, like insults gathered by many people.

Bai Shuangxing nodded: "Also, the disciplinary committee member was once bullied by naughty students in the class. Chen Miaojia said that he was excluded and isolated, and strange garbage was often stuffed into the desk."

"The school rules also mentioned that minced meat may appear in the desk."

Shen Chan gradually understood: "So—the content in the school rules actually corresponds to what the students have experienced?"

Bai Shuangxing was noncommittal, reached into his jacket pocket, took out the paper with school rules printed on it, and spread it out.

"This is the school rule given by the head teacher."

"Before we do that, let's recall the principal's version of the rules," she said.

Principal's Version Rules, Article 3.

[If you hear crying and choking in the corner, try not to move or make a sound.]

Ignoring the supernatural factors, if the background is substituted into the daily life of the campus——

The only ones who will cry in the corner are extremely sad students.

The disciplinary committee member who was excluded and bullied, Chen Miaojia who was beaten and reprimanded by his parents, and the classmate who was said by the students to be poor and on the verge of dropping out of school, they were all such people.

The contents of the school regulations are undoubtedly extremely indifferent and indifferent——

Don't talk to them, don't approach them, just pretend you didn't notice them, just leave as soon as possible and keep yourself safe.

The principal's version of the rules, Articles 4 and 5.

[There will be no minced meat and blood clots in the desk.If you find these two items in the desk, please keep quiet and just clean the desk silently.]

[During eye exercises, it is normal to occasionally hear screams, cries for help and whispers, please do not panic.]

Obviously, these two lines correspond to bullying incidents in the school.

The bullied students are being bullied and pranked day after day. They can't find anyone to confide in, so they can only suffer in silence.

And the rule of "Don't open your eyes for eye exercises" represents the attitude of this rule towards bullying behavior: don't participate, don't pay attention, and don't get angry.

Principal's Version Rules, Article VI.

[Once you see a huge manic monster in the school, please stand still and keep quiet.Running away will only make it angry.]

This is also easy to understand.

The irritable parents made unreasonable troubles at school, punched and kicked, and the students were powerless to resist, so they could only "keep quiet", as Chen Miaojia said, admitting that they were ignorant, and then apologized to their parents.

As for the principal and teachers, they just need to smile and let the turmoil pass as soon as possible.

Principal's Version Rules, VII.

[Trust the principal and the teachers in the school, they will always be your solid backing.]

Looking at this school rule at this moment, the initial feeling of creepiness is gone, and feel a little ridiculous instead.

"There are a lot of problems in this school."

Baishuangxing: "Or, in all schools across the country, there are such problems."

The indiscriminately parents, the naive but cruel classmates, the teaching staff who don't want to mix too much, and the gloomy and depressed students who have no way to vent their depression.

After she finished speaking, she stretched out her index finger and tapped lightly on the school rules Qin Mengdie sent to them.

"Then...Qin Mengdie became their head teacher."

Class teacher version rules, Article 4.

[If you hear crying and choking from the corner, even if you can’t see anyone, as a classmate, please come forward and ask friendly.]

Qin Mengdie wanted to tell them that people should not treat each other indifferently.

If you see a classmate who is crying alone, please don't turn a blind eye and walk away. Please go forward and ask patiently if they have encountered any difficulties.

Class teacher version rules, Article 5.

[5 There will be no minced meat and blood clots in the desk drawer.If found, please report to the head teacher immediately.]

This sentence corresponds to campus bullying.

No one should be targeted and humiliated for no reason. After learning what happened to the disciplinary committee, Qin Mengdie told him to learn to resist.

He has his own dignity, not a punching bag for other students.

The head teacher's version rules, Articles 6 and 7.

[6 Once you see a huge manic monster in school, please run away immediately and report to the head teacher.]

[7 If you are followed by unknown creatures in the corridor, please run away immediately and report to the head teacher.]

"Manic monster" symbolizes violent parents, and "unidentified creature tailing" may represent all the maliciousness that students may encounter.

No matter what, Qin Mengdie will protect them.

So no matter what happens, just tell the head teacher.

As the eighth rule says——

[Whenever and wherever, please ask the head teacher for help if you encounter danger.]

Xinghua No. 1 Middle School was established in a remote and backward small place.

There are always many sufferings and injustices here, such as poverty, loneliness, bullying, violence, and verbal humiliation.

Most people seem to have become accustomed to them, but Qin Mengdie is different.

In the white night built by her, those seemingly terrifying rules are actually a young teacher's most sincere and beautiful long-cherished wish for the students——

About empathy, kindness, resistance, and self-esteem.

Bai Shuangxing remained silent, looking at the third school rule on the note.

[Remember your appearance.Humans have eyes, noses and mouths, all are the same, no one is special.]

Perhaps, Qin Mengdie wanted to tell them that whether it was a female classmate from a poor family, a disciplinary committee member who was obsessed with death, or a rebellious student who was out of place and carefree, Chen Miaojia——

These boys and girls with different personalities, like everyone else, are never worse than others.

But Qin Mengdie died.

What did she discover that made the principal want to kill her?

His gaze shifted, and Bai Shuangxing's eyes gradually darkened as he stayed on the letter paper in his left hand.

Shen Chan lost her voice.

In the silence, Jiang Mian suddenly pulled Bai Shuangxing's sleeve: "Sister, I feel it."

The girl's face was as pale as paper: "Under the ground... there is a familiar feeling."

Subconsciously, Bai Shuangxing's heart skipped a beat.

underground.familiar feeling.The principal must never let others discover the secret.An oppressive feeling that makes all ghosts fear.

All the fragmented clues came together one by one, and a thought that made her hair stand on end suddenly emerged from her mind.

Bai Shuang stood up: "This may lead to the underground, let's look for a mechanism."

Shen Chan didn't understand what she thought of, but she nodded quickly: "Okay."

The principal's office is not very big, Shen Chan looked around, and not long after, she locked on the relatively empty bookshelf.

She tried to get closer, pushing it hard towards the corner of the wall.

The bookshelf wasn't too heavy, and it slowly moved into the wall with a long and heavy muffled sound.

At the same time, the bookshelf moved away, and the covered wall was exposed in the field of vision. Bai Shuangxing and Shen Chan paused at the same time.

... On the wall behind the original bookshelf, there is a dark hole, judging by the size, it is just enough for one person to pass through.

Bai Shuangxing's heart clenched quietly.

She already had a vague premonition about the principal's secret.

Shen Chan glanced at her: "Go in?"

Bai Shuangxing nodded: "I have the ability to protect myself, let me go first."

After she finished speaking, she took a step forward and looked towards the entrance of the cave.

Behind the opening is a deep and narrow staircase. Due to the small area, it is difficult to find that the space in the office has been tampered with from the outside.

Bai Shuang turned on the phone light and took a shallow breath.

The stairs went straight down, silently.

There is only constant silence and darkness around me, and the uneasiness in my heart is like an invisible palm, gently pressing on my chest.

The dark room was not deep, and when he reached the bottom of the stairs, Bai Shuangxing stabilized his mind and held up his mobile phone.

The white light instantly enveloped the entire space, and the cramped and oppressive atmosphere suddenly surrounded her, enveloping her.

Jiang Mian, who was beside her, trembled slightly and grabbed her cuffs tightly.

The dark room is small and there are not many displays. Looking up, there is a very weird...

idol.

It was exactly the same as the "god" she saw at No. 444 Baijia Street.

This idol is made of brass and is also covered with a harsh red cloth.

Under the fabric, you can see tentacles spiraling and growing. If you look closely, there are still human limbs carved in the tentacles.

Evil, bewitching, just one glance can give birth to the fear hidden in the hearts of human beings.

This is the secret that Qin Mengdie discovered.

——Sacrifice to evil gods.

It was the first time for Shen Chan to see such a scene, and after walking down the stairs, she froze in place for a moment.

There is no wind in the darkroom.

However, in an instant, a gust of wind came from nowhere and quietly lifted a corner of the red cloth.

Above Kong Ji's head, Bai Shuangxing heard a non-male, non-female laughter.

——In the blink of an eye, streaks of scarlet blood suddenly appeared on the wall of the dark room, spreading wildly like an endless sea of blood, trying to engulf them completely!

At the same moment, the system sound in my mind suddenly sounded.

"Ding dong!"

[Congratulations to the challenger for successfully interpreting the deep meaning of "school rules", and now the hidden task has been upgraded to a high-level challenge: the first school rule (solution)!】

"The school rules are Qin Mengdie's good wishes for the students. After her death, they turned into obsessions and remained in the white night."

"It's a pity that only the most important first school rule has not been conveyed to anyone - what is its content? Who do you want to tell?"

[Challengers, please live hard and find the real "first school rule"!】
