Dellson walked back to the door with a weird smile, where there is the master switch of the underground laboratory.

He tapped the switch a few times, and the fish tank, which had just regained its calm, began to vibrate again.

Li Yu was surprised to see that a black iron cage was lowered from above the water.

There was someone in the cage, wearing an oxygen mask, a wetsuit, and a fishing gun in his hand in a standard ready-to-shoot stance.

"Mr. Delson, you..."

"Shh." Delson put his finger to his lips, "Don't be nervous, look carefully."

The man coaxed in a low voice, and his words were filled with terrifying gloom.

Li Yu's fingers clenched into fists unconsciously, and his heartbeat continued to accelerate as time passed.

He was afraid of seeing a bloody scene.

The people in the cage also seemed a little nervous, his hands were shaking, especially when the mermaid swam towards him quickly, he actually took a step back, and the next moment his back was close to the cage, the trigger was pulled.

The black fishing dart popped out and shot straight at the merman's face.

Li Yu's heart seemed to be held by a hand, suffocating, suffocating, fearful, when all these emotions reached a critical point, the mermaid suddenly turned around, the flexible and powerful tail swept across the water, the fish dart made of stainless steel broke into three pieces.

Derson turned his head and smiled at the young man beside him, "This is their strength, and what you see today is only a small part of their ability..."

At this moment, the movement in the water interrupted his enthusiastic explanation.

The mermaid did not stop attacking and continued to move forward. Something similar to bone spurs grew on the back of his hand at some point, and he easily cut off the metal padlock hanging outside the cage.

The diver in the cage widened his eyes in horror and slapped the cage desperately, trying to get Dellson to lift the cage up.

However, the man standing outside in control of his life and death was unresponsive.

Li Yu, "Professor!"

Delson gave him a fierce look this time, "Shut up!"

Li Yu closed his eyes, "1551, save people."

"Immediately." 1551 left the words and disappeared.

The padlock that was cut off by the bone spur fell vertically into the bottom of the water, and the mermaid had roughly removed the cage door and wanted to reach out and pull the diver out.

Just then, a miracle happened, the cage suddenly rose rapidly, and the mermaid was thrown down.

Delson was stunned for a moment, rushed to the door, and kept poking at the display screen, cursing in his mouth, "Damn, what the hell is going on!"

It was not until the cage was completely out of the water that Li Yu was completely relieved, his knees went weak, and he leaned against the glass.

The male mermaid who had hit the glass returned empty-handed, but only barked his teeth at the young man, and did not attack any more.

door.

Delson was furious. No matter how he pressed it, there was no response on the screen, and the fingerprint recognition failed.

"Damn rubbish!" He punched the screen hard, turned back and ordered sharply, "Get out."

Li Yu hurriedly went out and left the underground laboratory with Delson.

As soon as you get out of the elevator, you will be greeted with warmth, which makes you feel alive again.

Delson ignored the young man, closed the elevator door, and went directly to the office on the top floor of the research institute building.

If a good lock is broken, it will be broken, Li Yu guessed, the logistics department will definitely be criticized.

As soon as the thought fell, the sound of the time broadcast sounded above his head, and it was time to get off work.

Li Yu quickly returned to the dormitory and took his lunch box to the cafeteria.

The cafeteria was on the first floor of the research institute building and was cleaned very well. At this time, there was no one to eat except the staff.

Because of the lack of materials and shortage of resources, don't think about big fish and big meat.

Li Yushun received a boiled sweet potato and a vegetable soup. After thinking about it, he asked for another steamed bun.

Probably because the original owner's lovable picture, coupled with the gauze on his head, was particularly distressing, and the cafeteria aunt took pity and specially stuffed him with an extra steamed bun.

Li Yu, "Thank you, Auntie."

"Thank you, you spend so much brains every day in order to make our lives better, so you should eat more."

There are only so many staff in the research institute. After working for a long time, the aunt can basically recognize everyone. As soon as I finish speaking, I remember that the young people are new.

Aunt couldn't help but persuaded again, "Don't keep thinking about saving points, your health is the most important thing."

Li Yu hadn't eaten since he woke up, and his stomach was growling with hunger. He smiled gratefully at his aunt, and walked to the corner to sit down.

Not long after, people who got off work walked into the cafeteria one after another.

They were in a group of a dozen or so with serious expressions. They should be discussing work. Occasionally, a few grinned and only talked to the people next to them.

The people in the various research laboratories in the institute are very gang-conscious and do not like to deal with people from other laboratories.

Li Yu lowered his eyes, took a sip of soup, and continued to chew the dry steamed buns, thinking about the things in the underground laboratory.

"1551, don't those three mermaids have totems on their faces?" At that time, the situation was chaotic, and he was afraid that he was wrong.

System, "Yes."

Li Yu wrote down this clue, thinking that he had to lift 001's hair to see what the totem on his face was.

After stuffing the last piece into his mouth, he left the remaining steamed buns and sweet potatoes in the lunch box and took them back to the dormitory.

After entering the door, the young man found a clean water cup with a lid from the cabinet, filled it with water, held it in his hand, took the heavy lunch box, and went out again.

When he was about to go downstairs, Li Yu wondered if 001 was there, and asked, "1551, is the target in the woods?"

"To the southeast of the woods, near the garbage disposal."

Li Yu's face was strange, stunned, pity, and unbearable, "Is he picking up garbage to eat?"

How miserable.

"...No." The system was speechless, "Go and see for yourself."

Li Yu, "...Oh."

Rather than getting lost again, he followed the map and compass all the way, and it took him more than half an hour to cross the entire forest to the edge.

In front of him is a huge deep pit, in which a lot of unrecyclable waste from the laboratory has been dumped.

Li Yu saw that in the pile of garbage, a man with disheveled hair was bending over to look for something.

I don't know if I noticed his sight, but the man's hand moved for a while, and he turned his head to look over.

Li Yu quickly hid behind a tree, frowning, recalling what the man was holding in his hand just now.

It's so far away that it's impossible to tell from the blurry outline alone.

"1551, what is he holding in his hand?"

"A broken semiconductor chip."

"I'll just say that this person is tricky." Li Yu hooked his lips, and then he became confused again, what is the purpose of the target's chip, will he repair it, and even if he does, there is no repair tool.

After going through this series of questions in mind, decided that couldn't get the answer right away, and they were temporarily put aside.

Li Yu stuck his head out again and frowned suspiciously, "Where's the person?"

Suspecting that he had missed it, he rubbed his eyes and blinked again, but still nothing.

Just as he was about to call the system, a flower suddenly appeared in front of him, and a tall man jumped down from the tree above his head and easily pressed him to the trunk.

Li Yu tried to struggle, but the more he moved, the stronger the man's hand became.

The shoulder blades were pressed against the hard trunk like an egg against a stone, almost fucking fractured.

Li Yu didn't pay attention to his face, raised his hand and clasped the wrist, begging for a detour, "It hurts, let go, brother, can I call you brother."

The youth's blue eyes became wet due to the pain, 001 was startled, his strength loosened, but he still maintained absolute suppression to prevent the enemy from cheating.

Li Yu was able to breathe, without struggling or screaming, just quietly clasping the hand on his shoulder.

Said to be confrontation, the young man's eyes are too gentle, not like.

Said to be resisting, the young man's hand was just holding his own wrist lightly, and it didn't look like it.

001 is rarely in doubt.

The man's body temperature is normal and his pulse is normal. In the woods before, Dylan's words were ugly, but there was one sentence that was true. The similarity between 001 and the alien species was too low, not to mention the mermaid who didn't even have legs.

Through the dirty black hair, Li Yu glimpsed that there was indeed an indistinct pattern on the man's face, which was much larger than the totem of the mermaid in the data.

Li Yu regained his senses and asked the system, "Is that him?"

1551, "Right now."

Li Yu snorted, suddenly raised his other hand, and quickly lifted the hair on the man's forehead, revealing the dirty face underneath.

To be honest, it's quite dark, and don't know how long haven't washed face properly, but can vaguely tell from the blurred outline that it should look pretty good.

Li Yu sighed inwardly, forget it, even if it looks a little ugly after washing it, he will admit it.

001 was taken aback by the inexplicable action of the youth, and after reacting, he blocked the hand and quickly backed away, his black eyes filled with great anger.

Li Yu glanced at the back of his hand, which was slapped red, and frowned. He could think of the hardships the man had endured over the years, and his anger disappeared at once.

He took out the lunch box from the big pocket of the white coat, opened the lid, and the steamed buns and sweet potatoes inside were hot and steaming.

001 was unmoved and watched the young man vigilantly.

Li Yu sat down with his legs crossed, put the lunch box in front of him, and was about to speak, when there was a ding in his head, and there was an extra screen in front of him.

[Danger level: A++]

[Protagonist's Secret: 1]

The young man's eyes were fixed on the front, the corners of his mouth were raised for a while, and then pressed down again, and he could not tell whether he was happy or unhappy.

Seeing him froze like a statue, 001 didn't respond for a long time, his alert gradually lowered, and the threatening growl in his voice disappeared. He always had only a defensive heart, and a trace of curiosity was born, and he couldn't restrain his desire to explore and understand.

Li Yu glanced at the man who was staring at him, very incredible.

The target's aggression is not strong, pretending to be a pig to eat a tiger, but all this is too far away from A++. Could it be that the back of 001's hand can also grow bone spurs like a mermaid, or grow a tail with bone spurs?

Li Yu thought, his eyes unconsciously fell on the back of the man's hands and bare feet.

Although the back of the hand is not clean, the bones are normal. As for the feet, they are really just feet, not forked fish tails that can be merged and reborn.

Li Yu failed to think about it, and turned to the next question. He frowned and asked the system, "This world really only needs to find a secret?"

1551, "The system will not go wrong. Of course, the possibility of later additions cannot be ruled out."

Li Yu thought about it, things would not be so simple, there must be a fraud.

1551 reminded, "Just take one step at a time. I advise you to leave quickly and be careful of someone coming."

Others bumped into it, and Li Yu didn't worry about it, he was worried about bumping into that dead pervert.

Delson's brain circuit is abnormal, the ghost knows what he will think and do when he sees himself with 001.

Li Yu rubbed his face in annoyance, sighed, and suddenly a straight ball came, "001, do you want to leave here?"

The man remained silent, still maintaining his previous state, and he didn't know if he heard his words.

Li Yu continued to take care of himself, "Delson took me to the underground laboratory, I saw your clan..."

He didn't stay in the underground laboratory for a long time, and he didn't see anything, but he knew that according to Delson's behavior, it was impossible to keep the mermaid in it like that, and other measures would definitely be taken to restrict the freedom of the mermaid.

What could it be?

The youth suddenly stopped in the middle of the conversation, 001 frowned slightly, took a step forward, thought of something, and then retreated.

Li Yu looked at him back and forth, too tangled, and clicked, "They were locked in a glass fish tank..."

A flash of light flashed in his mind, and he jumped up from the ground, "You want to save them!"

That's why men pick up chip fragments in the trash.

Li Yu smiled suddenly, his eyes curved into the moon, shining brightly, and the corners of his lips were lifted, revealing a set of white teeth.

"001, it's not that you don't understand anything, you are actually very smart, right?"

The man was still like a mute, refusing to say a word. He tilted his head slightly and glanced at the young man. In a flash, he climbed up the tree, jumped back and forth between the branches, and soon disappeared among the lush leaves.

Li Yu looked down at the food on the ground, thought about it, and moved it to a hidden location.

"I'm leaving, I'll keep things here, remember to eat when you're hungry, I..."

Suddenly there was a continuous clicking sound from the front, the sound of a foot breaking off a dead branch.

It looks like today's meeting is coming to an end.

Li Yu pursed his lips unhappily, whispered "I'll see you tomorrow", turned around and left.

He walked all the way and turned around, but he was disappointed that he didn't see the person he wanted to see.

"Su He."

When he heard the sound, Li Yu didn't realize that the other party was calling him, or that the system reminded him to realize it later.

The visitor is a woman.

Li Yu searched in his memory, it should be Kailin, she is the only female researcher in the institute, and she is the deputy director of the 003 laboratory.

It is said that Kaelin is the only daughter of the general manager of the underground fortress. Of course, no one can confirm this, because every time she is mentioned about her family, she keeps her mouth shut, and occasionally even shows fierce rejection.

The original owner had only been in the laboratory for half a month, and he had already met Kaelin twice because of similar things.

Kailin has a high position, but her work is also very complicated. She is mainly responsible for the external liaison and internal coordination of the No. 003 laboratory, as well as logistics management.

To put it bluntly, he is the head of the laboratory.

This seemingly hot-tempered deputy supervisor was accidentally seen by the original owner and secretly shed tears because of the death of the experimental subject.

He is tough on the outside but soft on the inside.

When there was an accident in the laboratory, Kailin happened to be absent. If she was there... Li Yu thought, she would definitely drag the original owner out of the unknown.

"Su He, stop for me." The hoarse shouts approached quickly, and a red figure came straight from the front right.

Li Yu was frightened by the other party's momentum to kill, and really stopped obediently.

Kaelin first carefully looked at the young man, and then raised her hand to touch the bandage on his head, "Why not continue to be hospitalized."

Li Yu, "There is nothing wrong with the wound, and there is no need to be hospitalized again."

Kaelin disapproved of the youth's indifferent attitude, and said sternly, "Then you shouldn't run around, but you should stay in the dormitory and have a good rest."

Seeing the young man nodding obediently, the words of criticism stuck in her throat, she took a breath, pinched the bridge of her nose tiredly and asked, "I heard from Qian Song, you asked him about 001."

Li Yu, "..."

Unexpectedly, Qian Song is still a big mouth.

He honestly admitted, "I asked, what's wrong?"

"That's why you came to him." Kaelin raised her head, her eyes reproached, "We can't be sure whether 001 is in danger or not. Those people are always going to provoke him. That's their business, you are not allowed to go. ."

Hearing this, Kaelin seemed to know something.

Li Yu, "But I heard Brother Song say that 001 is not dangerous."

"Little brother, you want to tell me something."

Kaelin folded her arms, leaned back, raised her chin and sneered, "Then do you know why that lunatic from Delson always runs to the woods."

Li Yu was at a loss, "Why?"

Kaileen, "Delson has been watching 001, and he never believed that 001 would always keep this cowardly look."

Li Yu can be sure that no one else should know about this matter, otherwise Qian Song would have brought it out when he persuaded him.

"You haven't told anyone about this, so why tell me alone."

"You are very smart." The smile on Kaelin's face was fleeting, and her expression was heavy. "Do you know where the research assistant before you went?"

Li Yu was stunned for a moment and shook his head. He didn't know that the original owner's current position was occupied before, thinking that the laboratory was too busy to recruit new people.

Kaelin, "I don't know either, he just left a resignation letter in the dormitory and disappeared."

Her face was ugly, her brows were tightened, and she seemed a little confused, "I know that his disappearance must be related to Delson, and that person must have discovered Delson's secret."

Li Yu, "What does this have to do with 001."

"How can it be okay, why is Dyerson paying close attention to an experimental subject that has no value?"

Kaelin solemnly warned, "Stay away from everything related to Delson and do your job well. Su He, you are only 20 years old and your life has just begun. Don't ruin your life just because of curiosity."

"I see." Li Yu agreed verbally, but in his heart it was another matter.

Not only will he continue to approach 001, but he will also leave this ghost place with 001.

Seeing that the young man didn't screw with her, Kaelin was relieved, "Let's go."

The two just walked out of the woods on the front foot, and the irrigation system in the woods started on the back foot, but it stopped after only 30 seconds of operation.

The water on the ground is polluted and cannot be used. Humans only rely on this poor groundwater, and they don't know how long they can survive.

Li Yu turned back, his eyes narrowed slightly, and he seemed to see a figure passing over the edge of the tree trunk.

"Don't look, hurry up." Kaelin urged impatiently.

Li Yu followed closely, and while Kaelin was not paying attention, he waved at the woods.

In the dormitory, Qian Song came back from dinner, changed his clothes, and was about to go to the fitness center.

Li Yu thought about it and said, "Wait, I'll go too."

Qian Song raised his eyebrows, "I tried to persuade you not to go, but I figured it out today."

Li Yu opened his closet, picked out a pair of short sleeves, and put on a pair of shorts, "It's always good to exercise more, so as not to encounter the last time, the gun will not be stable."

"The same thing won't happen again," Qian Song said. "Two or three minutes before leaving get off work, someone from the logistics department came and said that all the glass should be replaced with the latest explosion-proof glass."

Li Yu asked casually, "What about the underground laboratory?"

Qian Song was surprised, "Mr. Delson has taken you there?"

"Yes, just an hour ago."

"This is also a kind of affirmation from the professor." Qian Song said with a smile.

Li Yu nodded stiffly, his eyes still stopped on the face opposite, as if seeking the previous answer.

Qian Song, "Probably not, because it's not necessary."

Li Yu's heart sank suddenly, some bad guesses, and anxiously asked, "What do you mean?"
