The atmosphere dropped to freezing point.

The evil ghost behind him radiated icy cold air, Wen Chuchu didn't dare to turn his head, even if he just turned his back to it, he could still feel the mad killing intent of resentment.

There were more and more words "death" on the paper, and the weight on her back was gradually increasing, gradually making her unable to breathe.

Tonight...absolutely screwed.

There was nothing they could do to fight back.

The room was quiet, only the sound of the pen tip scratching across the paper, and suddenly someone called her: "Can you hold on?"

Wen Chuchu looked up, it was Bai Shuangxing.

She hooked her mouth as she spoke: "You haven't let go, you are already very powerful. If it were me, I would have been yelled and terrified a long time ago."

Wen Chuchu was a little dazed by the praise, maybe because she realized that someone was with her, the extreme fear faded a bit.

"Bai Ye will not have a fatal problem."

Bai Shuang said: "There is still a chance."

After she finished speaking, she raised her free left hand, and when her arm approached, it brought a fresh and cool fragrance of shower gel.

In the astonished gaze of the other party, Bai Shuangxing held Wen Chuchu's right hand holding the pen.

Wen Chuchu opened her eyes wide: "Wait—!"

That ghost hand is holding her right hand, Bai Shuang is doing this...

Didn't it come across it directly!

It feels a little cold to be in direct contact with ghosts.

Bai Shuangxing's expression remained unchanged, and he blinked at her: "Don't be afraid, let's continue to ask it questions."

Wen Chuchu stared at her blankly.

Being held by her left hand, the bone-chilling chill on the back of her hand instantly diminished a lot, replaced by the warm heat of the girl's palm.

The despair of facing the evil spirit alone quietly faded away, she took a deep breath and nodded.

"The rule of Please Pen Fairy is that we ask questions, and it must answer."

Bai Shuangxing lowered his eyelashes: "This is a rule, and it is also an iron law. Even a pen fairy should not violate it."

Otherwise, after those lonely ghosts are invited, why do they have to answer the questions obediently? If they want to eat people, they can just do it.

The reason for answering honestly is probably because it is subject to the rules of inviting ghosts.

Xu Qingchuan also calmed down: "But even if you ask a question, it can answer it right away—"

Then continue to approach them.

wait.

Xu Qingchuan had a flash of inspiration: "How about pi? It can never be answered!"

"No way!"

Wen Chuchu shook her head: "We're still holding the pen! If it keeps writing, we'll suffer as well."

In the pen fairy game, it is taboo to let go halfway.

Asking about pi hurts the enemy eight hundred and self-damages one thousand. If the pen fairy is allowed to write for a long time, they will have to hold the pen for the rest of their lives, and they will never be able to end this trial.

After discussing for a while, the gel pen shakes faster and faster.

The coldness penetrated into the bone marrow, and seeing something was about to struggle out, Xu Qingchuan tentatively threw out a question: "pen fairy, what is the last hundredth digit of pi?"

There is no pause.

One movement of the nib leaves dark black Arabic numerals: 9.

...No!

Xu Qingchuan went crazy.

Faced with such a frenzied problem, don't you even need to think at all?

The narration didn't stop, getting harsher.

[Things have come to this point, you finally realize a fact: you are finished.]

[The pen fairy knows everything that exists in the world.You have provoked this resentful undead, and now it is about to move, and it is about to come to you—]

It spoke passionately, mobilizing the atmosphere to the climax, but before the last sentence was spoken, it was interrupted without hesitation.

Baishuangxing: "pen fairy, how to prove Goldbach's conjecture?"

For a moment.

The whole world fell silent.

Wen Chuchu was stunned: "What is Goldbach...?"

"A mathematical problem that has not yet been proven."

Xu Qingchuan was startled for a moment, and then his eyes cleared up: "So far, no one knows the answer."

correct.

Maybe... this is the way to deal with Bixian!

It knows everything that "has been", but what about this world-class problem that no one can crack, and there is no answer at all?

Answering the questioner's question is the ritual rule that the pen fairy must follow.

Once the pen fairy can't answer, can't write the answer, and breaks the rules... what kind of punishment will he receive?

As he expected, the gel pen paused on the paper for a moment, and after a while, he appeared a bit dazed for the first time.

This is a difficult question that has no answer, but because of the rules, it must be answered.

The pen fairy began to write with great difficulty, and at the same time, the narration also sounded hesitantly:

[You have provoked the resentful undead, now it is about to move, and it is about to come to you——]

[Uh, to prove a world-class mathematical problem.]

System 056 monitoring in the dark: ...

What kind of plot unfolds!!!

"It's actually writing."

Seeing the gel pen swaying, Xu Qingchuan felt nervous and looked at the pen and paper on the table.

The pen fairy didn't have a clear idea, so he wrote with a hammer here and there, and his handwriting became more and more scribbled, bringing out several ink blobs.

It has been written for a long time, so long that it gradually forgets that it was originally intended to kill them.

"Until today, I finally understand a truth."

Feeling the growing anxiety and irritability of the ghosts behind him, Wen Chuchu said: "Mathematics problems are more terrifying than ghosts."

Xu Qingchuan: "Thinking of my high math test... Is this considered to be connected with fate?"

056 just wants to sew their mouths shut.

Please, now is the critical moment to invite a pen fairy, the most thrilling and exciting part in a horror movie, is it plausible to chat like this?

Bai Shuang sat lazily on the sofa like a cat, looked at the gel pen frantically waving, raised her eyebrows slightly: "Can't you do it?"

This person didn't follow the routine. When she spoke, not only 056, but even the pen fairy all trembled, lest she would do some small tricks again.

Bai Shuangxing yawned: "What is omniscient and omnipotent, it seems that it is nothing more than that."

Alas.

Xu Qingchuan quietly glanced at the long-haired female ghost behind Wen Chuchu.

Well, the face is distorted, and it looks like it wants to kill.

It's a pity that the question is not finished, and it can't stop writing.

It doesn't understand.

It clearly knows everything, and even has a certain degree of prophecy ability. In this world, how can it be difficult to live with problems?

how is this possible?!

At the round table, Bai Shuangxing changed the topic: "But think about it carefully, it's actually expected that you can't write the answer to this question."

The female ghost looked up angrily, and heard her continue: "Omniscience and omnipotence, this is the ability that countless people dream of. But after you got it, what did you do with it?"

pen fairy was taken aback.

"You've been answering trivial questions."

Bai Shuangxing looked at it: "Can I pass the exam? Does that person like me? What is the winning number in the lottery tomorrow? Do you think... these questions are worth it?"

The pen that was swishing wildly, slowed down.

"They only bury your strength, don't they?"

The female ghost had a ferocious face, but Bai Shuangxing looked directly into its eyes with a sincere and calm tone.

"Look at this conjecture. There are countless people in the world who want to solve it, but they can't do it in their lifetime. What about you? You have the innate advantage of omniscience. Maybe you can know the answer with a little more effort."

flicker.

This is definitely cheating!

056 had a bad secret, and watched Bai Shuangxing's smile deepen, and a small arc formed in his phoenix eyes.

"Examination results, dating results, lottery numbers, these are all questions that can be known in a few days, and they can't reflect your strength at all."

Her tone was soft, like honey, and she smiled slightly when she said this: "But this topic is different."

"Maybe...it's something only you can do," she said.

silence.

Still silent.

After a brief silence, the narration sounded again.

[Looking at the pen in his hand, he realizes it.]

[Yes, you obviously have a unique advantage, why waste it?It used to feel that everything in the world was boring, and it could see the answer at a glance. Only by killing people can it get a sense of unknown pleasure——]

[until today.]

[As it was destined, it encountered this unsolvable problem.]

[It turns out that there are things in the world that it doesn't know.After many years, it finally had a chance to rethink.]

The plot was too ups and downs, Xu Qingchuan and Wen Chuchu were both stunned, and heard a soft sound in their minds.

"Ding dong! Congratulations to the challenger for completing 1/4 of the main mission!"

"The filming of the first act of "Evil Ghosts Will Show" has been completed, please choose an appropriate title for this unit story."

"Here are some great options for you—"

As the monitoring system for this challenge, 056 somehow had a very bad premonition.

This time White Nights uses movies as the carrier. Every time a unit story ends, the challenger with the most outstanding performance will be allowed to choose the subtitle of this scene.

In its presupposition, the title of the first act should have been in the style of "Pen Fairy" and "Desperate Night".

But at this moment, when the lines of text appeared in front of Bai Shuangxing's eyes, it was rarely silent.

"Option 1: "This Pen Fairy Is Not So Cold""

056: ...

What a weird option!

"Option 2: "Encouraging Learning""

——What is this!

"Option 3: "Goldbach's Redemption""

——Is it reasonable to appear in a horror film?!

"The force on the pen is getting weaker and weaker."

Xu Qingchuan hasn't come out of the shock yet: "The pen fairy can't answer the question, which violates the rules of the ceremony, is it backfired?"

"Well. Ghosts who violate the rules will be punished by Bai Ye."

Wen Chuchu patted her heart: "It's dangerous...but then again, if the pen fairy proves this conjecture, what should I do?"

"There are still many topics."

Bai Shuangxing: "For example, the very famous question, 'Can Almighty God create a stone that he cannot move'."

If it was created, God couldn't move that stone, so he couldn't be called "Almighty".

If it can't be created, God can't even create a stone, and it's not "omnipotent".

This is a logical paradox that never has a correct answer.

Wen Chuchu is right, math and logic problems are sometimes scarier than evil spirits.

After she finished speaking, she paused, her eyes lingering, and she selected a line of text that floated in front of her eyes.

056 followed her gaze and felt a throbbing pain in his nerves.

Sin.

It is a horror movie shot with painstaking efforts. The subtitle of the first act is:

"When Math Comes Knocking".

For a moment, it wanted to cry.

Looking at Pen Fairy again, he has already forgotten the troubles of the world, and filled sheets of paper with obscure mathematical formulas.

Loud narration filled the room.

[It turns out that it can shine brightly even when it failed to achieve anything in its lifetime; it turns out that there are still things waiting for it to accomplish in this world——]

[Goldbach's conjecture, and more unsolved mysteries!]

056: ...

Wake up, you went to the set of an inspirational film, pen fairy!!!
