In order to save energy, all temperature control systems will be turned off at night, and the underground fort is located about ten meters underground, and the temperature is about 12 degrees Celsius.

This temperature does not cover the quilt, and sooner or later it will catch a cold.

Li Yu went out with a small pink blanket, and according to the system prompts, he cleverly avoided the patrolling security all the way, successfully went downstairs, and got into the woods.

After entering the woods, the system began to guide the way, "Turn right after 100 meters..."

Li Yu trotted all the way as instructed to reach the finish line, but did not see the man.

"1551, where is the target person?"

"Look up."

001 was sitting on a branch with his back against the trunk, already awake, he sat up lazily, bent one leg, and did not put the young man who suddenly appeared below into his eyes.

After a brief contact in the afternoon, he had determined that the youth was not his opponent.

Li Yu freed up a hand and waved at it, "I'll bring you a blanket."

001's eyes moved and landed on the light-colored blanket. After a while, the others got up and jumped to another branch, with unbelievable agility.

Li Yu felt that maybe every time 001 was beaten, the injury was not serious, and the mermaid's strong physique might not have been inherited from him.

"1551, can you do a genetic comparison?"

"Yes," 1551 said, "but you need to wait."

The man turned around and disappeared, and Li Yu was not in a hurry to go back.

He hugged the blanket tightly, squatted under a tree, and said to himself, "I have no ill will towards you, I just want to make a friend, I won't take the blanket, you keep it for the night, and Delson, he Not a good guy, stay away from him."

"By the way, I met a soldier today. He told me that the outside world is very exciting and dangerous. I want to leave here. Would you like to come with me?"

The temperature was not high, and the woods were even colder. Li Yu couldn't help it, and shook off the blanket and wrapped it around him.

The body gradually warmed up, and the young man yawned and continued, "Have you eaten the food delivered at night? I'll be here tomorrow morning."

He rubbed his eyelids, and actually started to feel sleepy, and the words in his mouth became vague, "Don't think I'm annoying, I..."

"I just want to be nice to you."

The youth's voice disappeared into the night, and after 001 appeared in the tree opposite, he yawned again, tightened the blanket on his body, and tilted his head to one side.

001's ears are much sharper than ordinary people, and his heart beats with the youth's breathing.

After a while, the man walked over and squatted about a meter in front of Li Yu.

1551's test results came out, but it was not busy waking up the host, but observed 001's every move.

001's breathing was very light, and his eyes looking at the young man were very focused and full of curiosity.

For more than ten years in the laboratory, he was faced with Derson's disgusting face, and after leaving the laboratory, he was faced with abuse and beatings from the superiors of human beings, and no one really treated him better.

But at this moment, the innate ability to perceive danger and human emotions accurately makes judgments for him, and the young man in front of him is different from those people.

001 looked up at the dome, where there was a faint light.

He frowned in dissatisfaction, the light was too dim, so he couldn't see the young man's face more clearly.

001 didn't tangle too much, his legs were straight, and he took a half step forward.

The young man's skin is very white, his eyelashes are thick, and the corners of his mouth are naturally upturned. Even when he falls asleep, he seems to be smiling.

001's language vocabulary is too lacking, he can't find words to describe it, he just thinks this face can make him feel at ease.

Li Yu slept uncomfortably with his shoulders slanted and his head down. He changed positions in a daze, but his back was empty, and he fell backward uncontrollably.

Subconsciously, he tried desperately to reach for something, but a hand grabbed his wrist instead.

That hand was a little rough, and before he could feel it, the other party pulled him forward with all his strength.

Following the force, Li Yu regained his balance, caught a glimpse of the other party trying to run, and quickly grabbed the man with his other hand, "You are not allowed to go."

All the cells in 001's body were in a state of preparation, and his body was so violent that he was about to push him away when the young man suddenly blew against his arm.

The cool breath brushed against the skin, numb and itchy, and 001 was stunned.

Li Yu carefully touched the cut on the man's arm, "Does it hurt?"

There was a forefinger-length wound on the man's sturdy arm. The wound was not smooth, but it was fresh. The blood smeared nearby was not dry, and it should have just been scratched.

Knowing that he couldn't get an answer, Li Yu sighed, "Why didn't you be careful."

Looking at the young man's caring eyes, 001 felt a heat in his heart, his lips moved, but he still didn't speak.

Li Yu didn't notice his subtle reaction, and thought, "I'll come here to find you tomorrow morning."

He was afraid that the man would not understand, so he gestured a few times with his hands like a fool.

Looking at his empty arms, 001 frowned slightly, his head lowered.

Li Yu bent down and looked up at the man's face, "What's the matter with you?"

001 didn't know what was wrong with him. The place where his arm was held was slightly hot, but his heart was empty.

At this moment, 1551 suddenly said, "Qian Song is awake."

Li Yu couldn't care about anything now, picked up the blanket on the ground, stuffed it into the man's arms, and ran away.

On the way back, the systematic genetic comparison report came out.

001 has the same genes as humans.

Li Yu, "I don't believe it, intuition, and I can also feel from Delson's attitude towards 001 that he is by no means an ordinary human being."

1551, "But my data tells me he is."

Li Yu said as he ran, "Anything is the world, and what the eyes see may not necessarily be true."

1551 could not refute.

On the other end, 001, who was discussed by the two, was still in the same place.

The blanket in his arms was soft and warm, with a faint scent, very similar to the smell of youth.

He was curious in his heart, lowered his head and sniffed, and then seemed embarrassed, he quickly raised his head, folded the blanket neatly, held it in his arms, and returned to the tree.

The man was agile, his legs were strong, and he climbed up the treetops in twos and threes, watching a dark figure shuttle through the woods, pass the garden, and enter the white building.

Li Yu ran all the way, and was about to reach the dormitory, and was caught by the patrol team.

1551, "It's said to run slower, you won't be able to stop the car."

Li Yu, "Who knew it would be so unlucky, this person would suddenly turn around."

It was not an ordinary patrol officer who caught him, but the captain of the patrol team. He was wearing a black uniform, holding an electric baton, and rudely pointed the torch directly at the young man's face.

"Which dormitory, why don't you stay in the room." The captain spoke fiercely, as if he was interrogating a prisoner, "You don't sleep in the middle of the night, where have you been? When did you leave the dormitory?"

Li Yu blocked the light with his hand, and made up a lie without blushing, "I couldn't sleep, so I walked in the garden downstairs."

He was anxious, grabbed the system and asked, "Where's Qian Song, has he noticed that I'm not here?"

1551, "I haven't found it yet, he's in the bathroom."

Li Yu was anxious like an ant on a hot pot, but the patrol captain on the opposite side didn't believe his words, and took out the walkie-talkie to notify his colleagues in the monitoring room to call for monitoring.

Hold down the anxiety, Li Yu ordered, "1551."

1551 tacitly understood what he meant, "Leave it to me, don't worry."

Li Yu felt a little relieved, and began to count a few seconds in his heart. When he reached sixty, a voice came from the slap-sized walkie-talkie.

"Report captain, between 1:25 and 2:08, there was indeed a young man sitting in the garden."

Captain, "What did he do?"

Opposite, "first walked in the garden, then sat on a bench in a daze, and then, seemed to fall asleep later..."

Things were unexpected, the captain turned off the intercom, his eyes were bigger than cows, "There is a curfew after 0:00 in the accommodation area, and no one is allowed to go out, didn't you know before?"

"I don't know." Li Yu said honestly, "No one told me."

Qian Song and the others didn't tell the original owner about it, they probably forgot, and the dormitory didn't post relevant notices.

The captain was about to swear when he heard the young man say, "Brother, I've only been here for half a month, and I'm not familiar with the rules and regulations. I promise to study hard when I go back, and I'll never do it again."

The requirements for entering the institute are very demanding, and new recruits are rarely hired.

Hearing that he was a newcomer, the captain suddenly remembered, "Are you from Laboratory 003?"

Li Yu nodded and said yes, "Brother, can I go back to the room?"

The people in the 003 laboratory are all baby bumps, the captain will naturally not be embarrassed anymore, he waved his hand, and signaled the young man to leave quickly.

Li Yu smiled and said thank you, and continued to go upstairs. After a few steps, he heard the patrol captain's walkie-talkie ring again, and the voice from inside was trembling, as if in extreme fear.

"Captain, I, I heard a sound, clinking..."

With the trembling voice of the other party, Li Yu's heart also rose, swaying between returning and not returning to the dormitory.

Li Yu, "Has Qian Song found it?"

1551 said that not yet, it paused, and his tone became more relaxed, "He has returned to the bed, and he didn't realize that you were not in bed."

The frightened voice on the walkie-talkie was really intriguing. Since he no longer had to worry about the other side of the dormitory, Li Yu resolutely chased in the direction the patrol captain left.

The captain went all the way down to the second floor.

The patrol member who reported the situation before was holding a walkie-talkie and stood in the corner at the end of the corridor.

The captain had a bad temper, so he approached and slapped the opponent on the shoulder. Even though he knew the sound insulation effect of the dormitory door and wall was extraordinary, he still restrained his voice and said, "What does it look like to be timid?!"

The team member held the flashlight tightly, "Captain, I, I really heard it."

The captain glared at him and listened attentively with cold brows and eyes. It was quiet in the middle of the night, except for the sound of breathing beside him, there was nothing else.

He frowned, and was about to scold someone when he suddenly trembled, and there was a real sound, clinking, as if someone was hitting the wall with a hammer.

"Someone is working in the middle of the night?"

A clear voice sounded faintly.

The captain shivered in fright, turned around with his gun drawn, "Who!"

Li Yu's head was tilted instantly, and he was not hit by the gun. He raised his hand and showed his white teeth, "Brother, it's me."

The captain's tense back suddenly collapsed, but the toughness in his mouth did not diminish, "What are you doing here, why don't you go back to the dormitory."

Li Yu looked frank and innocent, "I just heard your voice on the walkie-talkie. I'm afraid something will happen, so I'll come and have a look."

Hearing this, the captain's tense nerves were completely relaxed, and he tapped his finger on the young man's shoulder, mocking, "Little brother, do you have any misunderstanding of yourself? If something really matters, what can you do with your small body?"

Li Yu is quite confident, "It will be useful."

The captain waved his hand, "Okay, okay, hurry back to the dormitory."

Li Yu's ears directly filtered out this sentence, raised his feet and walked forward, the ding ding sound continued.

He took a step forward and finally stopped in front of a wall and put his ear on it.

After listening for a few seconds, Li Yu pointed to the wall and said, "The sound came from inside."

The patrol captain and the team members also put their ears to the wall, and the clanging voice became clear and close at hand, and the two of them saw fear in each other's eyes at the same time.

Li Yu, "It may also be someone from a nearby dormitory who is nailing something into the wall."

The patrol captain opened his mouth and finally said nothing, but gave his subordinates a wink.

When the subordinates reacted, they seemed to have discovered the truth, and the fear in their eyes was even greater.

He swallowed hard and walked up to the youth, "Sir, I'll take you back to the dormitory first."

Li Yu, "I can go back myself."

Team member, "I need to make sure you are safe."

Li Yu knew that the sound of Ding Ding Dangdang was from an unusual origin. The two of them should have wanted to let him go, and then called others to come over and deal with the sound source together.

He pursed his lips, looking unhappy, "Okay then."

The patrol members breathed a sigh of relief and could not wait to lead the way.

Li Yu followed back upstairs, closed the door, sat back on the bed, and let the system turn on the live broadcast.

In the picture, the patrol leader is informing the other team members to rush to the first floor immediately, and then debug the walkie-talkie channel, and make a request to the defense team, "Please send reinforcements immediately, hurry up."

Sure enough something happened.

Li Yu sweated inwardly, and his heart beat faster. On the bed opposite him, Qian Song was snoring, and his voice was long and continuous, very distinctive.

The soldiers of the defense team came quickly, each carrying weapons and wearing special explosion-proof uniforms, waiting solemnly.

The patrol captain pointed to the wall that made the sound, and one of the defenders took out a small device, which was connected to a small microphone.

Li Yu recognized that this was a sound storage device.

As soon as the device was attached to the wall, a tinkling sound came from the device, accompanied by a sound similar to breathing, which, strangely, was not too clear.

The sound of breathing was more urgent and heavier than that of human beings. Li Yu couldn't help thinking of another creature, a xenogeneic species.

Think of the strange beating again...

No, the aliens not only sneaked into the underground fortress, but also secretly went to the laboratory to the tunnel?

Li Yu's eyes widened in surprise, and he became more and more nervous, for fear that something would suddenly emerge from the ground.

In the light screen, the defender had the same idea as him. He had moved the device and put it on the ground. The sound became louder, and as the device moved, it became clearer and closer.

But then, the sound suddenly disappeared.

The eerie viper that was about to attack was alerted by the ground and began to retreat.

The defenders responded quickly, and the defender who was the captain made a few gestures in silence.

After receiving the instruction, the team members were divided into three groups and acted in three groups.

One group was on guard in place to prevent the aliens from breaking through the ground and running out and attacking the research institute building; one group left the building and went to find the loopholes in the dome to prevent more aliens from sneaking in.

The last group, headed to the woods.

The fortress under the research site is of immeasurable importance. In addition to the 24-hour patrol by the patrol team, the defense team will conduct a daily carpet search to confirm the safety of the surrounding area.

They can be 100% sure that there are no traces of excavation on the ground, so the woods have become the biggest suspect.

Li Yu hugged the quilt nervously, sweating a lot on his body, agitated by the icy air, and goosebumps all over his arms and neck.

"1551, is the target in the woods?"

"Yes." After 1551 finished speaking, he cut out another shot for him.

The first time the patrol entered the woods, 001 woke up from his sleep, hugged the blanket and moved to the edge of the woods, and continued to sleep.

And in the garbage dump on the ground not far from him, several black, tall and thin shadows drilled out from it.

001 tightened the blanket in his arms and watched indifferently.

Li Yu, "Won't it get in the way with such long hair?"

1551, "...get used to it."

Li Yu, "I found a chance to cut it for him."

After talking, he remembered that he couldn't get a haircut, and said to the system, "1551, when I'm free tomorrow, show me Grandpa Tony's haircut teaching video."

1551, "Wash, Cut and Blow Trilogy?"

Li Yu hummed and focused on the live screen again.

The forest covers more than 30 square kilometers. With this search alone, who knows that it will take the Year of the Monkey to find the entrance to the cave. The operation took less than three minutes, and the team leader picked up the walkie-talkie and asked for support.

Finally, a word of caution, do not disturb any residents.

When saying this sentence, the group leader did not think about it, as if the same thing had happened and made the same decision.

Li Yu touched his chin and narrowed his eyes slightly. The defense team concealed the news of the alien infiltrating, just because they didn't want to cause panic among the people.

But he doesn't think it's right.

Digging up the dome and sneaking in, and then digging a tunnel from the woods to enter the laboratory, it shows that the aliens are very clear about the importance of the laboratory to the bunker, whether it is to develop more powerful weapons, or to restore the serum that can save mankind, for them, Just means casualties and disappearance.

Not every Xenomorph only has the killing instinct in their brains, the part of them that retains the IQ is thinking.

They are not walking dead, but another creature mutated from humans.

This is a very scary thing. If we cannot coexist peacefully, the two sides will die sooner or later.

Digging tunnels is just a trivial episode on the road of war. When humans retreated and hid, there were countless supplies that had not yet been taken away, and there were many ways for aliens to break through the fortress.

As long as they have enough weapons, and then assemble the team, the bunker can be captured at any time.

Li Yu said seriously, "I think they should tell everyone about these things, so that human beings have a sense of urgency. The residents don't know it, and they just think they can live a stable life underground. After a long time, their combat effectiveness will be lost..."

1551 said mercilessly, "Even if they have good combat effectiveness, they are still not opponents of alien species."

Li Yu opened his mouth and finally chose to shut up.

1551 said, "The possibility of peace is also very small, because the aliens are bloodthirsty and they need food."

Li Yu continued to be silent, and after a while he asked, "Is there a leader among the different species?"

1551 said it was not very clear, "You know that my detection range is only 500 kilometers, and the earth is too big."

"Okay." Li Yu felt that the system's voice seemed a little lost, and said without hesitation, "Touch your head, it's okay, you are already very good."

The system is really powerful, and with its help, he is fully confident that he will survive on the ground with 001.

In the light screen, reinforcements have arrived. In just 20 minutes, most of the woods have been searched, and they are gradually approaching the direction of the garbage dump.

Li Yu's eyes moved, and he stopped on the small screen in the upper right corner.

As the defenders got closer and closer, 001 couldn't sleep any more, he let out a grumpy growl in his throat, hugged the pink blanket, and jumped to a higher branch.

From the beginning to the end, he had no plans to remind the defenders.
