The boy crept barefoot on the floor of the hallway, which was so silent that a pin could be heard, and the fluorescent lamp above his head made the sizzling sound of electricity, and he walked against the wall without making the slightest sound.

The labyrinthine passages inside the institute were originally designed to make it more difficult for the enemy to occupy the place in the event of war, but tonight it also provided room for the boy's escape from prison, and he was able to maneuver with the help of the guards. The entire research institute is extremely well defended, and it is the United States Marine Corps who is responsible for guarding them, and the research institute on weekdays is five steps, one post, ten steps, and one sentry, and those heavily armed soldiers have the power to shoot at any suspicious person, and they will never give the boy a chance to escape, but tonight is a periodic shock, and everyone is transferred to the front line to resist zombies and hunters, and the research institute at this moment is an empty city.

Today, there is only a five-man patrol team in the institute, which rounds around every fifteen minutes and returns to the same location, and if the boy does not escape within fifteen minutes, his disappearance will be discovered.

The boy was located on the third basement level, and there were only four elevators leading to the surface, and the elevator shaft was located in the middle of the research institute building, almost five hundred meters away from the boy.

Once on the ground, no one will be able to catch him. He was able to take advantage of the chaos of periodic shocks to escape.

There are many children in the institute, the eldest is eight or nine years old, the youngest is five or six years old, they have lived here since birth, day after day injections, medicines, sleep, and electrotherapy, but no one has ever thought of escaping, they were born here, they can't even wear clothes without the care of the doctors, and the doctors warn the children that the outside world is dangerous, there is no food, no water, and there are man-eating monsters.

But the boy was an exception, and he was different from everyone else.

He was going to get out of here, he was tired of being kept in a cage as a guinea pig for observation, and the boy regretted that he only had fifteen minutes to escape, otherwise he would have wanted to kill the doctor who beat and scolded him every day.

The boy walked forward with his waist on his waist, avoiding the surveillance of the cameras all the way, he was only ten years old, he was thin and small, and his movements were as flexible as a monkey, the original tight surveillance was full of loopholes for him, and the boy's escape plan had been prepared for a long time, this line he had simulated in his mind thousands of times, and the dead spots of each camera were in his mind.

The boy stopped around the corner, there was a camera on the top of the passage behind the corner, he had to cross this fork in the road, but that camera had no dead ends, as long as he passed by, he would definitely be discovered, the boy could not expose himself to the camera's field of vision, once his whereabouts were exposed, the entire basement of the institute would be blocked, the elevators would all be closed, and the boy would be unable to fly.

He looked up at the ceiling above his head, pulled a knife out of his sleeve, pressed his thumb into the palm of his hand, and quietly leaned forward, the smooth blade reflecting the position of the camera like a mirror.

The boy closed his eyes and took a slow, deep breath with his back against the wall, he remained motionless as the minutes ticked by...... He was waiting for an opportunity, but it wasn't always there, and he could only pray that his luck would be better.

There was a muffled "boom" overhead, and the ground suddenly shook slightly, and fine floating ash fell in a flutter, and the boy opened his eyes, and this was what he was waiting for...... A heavy bomb exploded, and the shock wave shook the entire research institute building, and he waved his hand the moment the building shook, and the knife was pinpointed to the top of the corridor behind the corner, cutting off the camera line.

Anyone in the monitoring room will notice that one of the cameras has suddenly lost contact, but he will assume that it was caused by the explosion of a bomb just now, and that the electronic equipment in the institute is often affected by the explosion, which is a common occurrence and does not cause any tension.

The person in charge of fixing the camera will not be here until tomorrow, and the electricians should all take refuge in bunkers by this time.

The boy withdrew the knife and moved on.

He only had fifteen minutes, and if his escape plan failed and he was caught, he would not be directly executed, but he would definitely be put on a restraint suit and locked up in a confinement cell, and it would be difficult for him to see the light of day again in this life.

The doctors didn't care much about their lives, and every day children died in their experiments, which were covered with white cloths and carried out on stretchers and sent directly to the crematorium. The experimental objects are like leeks, one after another.

The boy walked through the corridor, there were locked iron doors on both sides, this is one of the children's living quarters, behind each iron door is an experiment, those children have been sedatives and are now asleep, the iron door is pasted with various color logos, the triangular logo on the door at this end of the corridor is blue, there is a Roman numeral "I.", which means the first type of experiment, the children behind these doors can still maintain the thinking and action ability of normal people, no different from ordinary people, the further you go in, the color of the logo gradually deepens, the number from "I." Becoming "II.", the second type of test subject is to be strictly controlled, their doors are electrified, people in the room will be shocked when they touch the door lock, and the logo on the last door has changed to crimson with the number "III.".

The third type of experimental subjects, these iron doors seem to be locked forever, the boy rarely sees the children who live in them, the second type of experimental subjects have begun to isolate from other children, the third type of experimental subjects have never been seen, the living area of the third type of experimental subjects is strictly forbidden for anyone to approach, tonight the boy needs to take a shortcut to the elevator, so he has to pass through here.

He hurried through the hallway, the iron doors on either side of which looked as thick as the vault gates, and with a small thick glass window, it was hard to imagine what it was that required such close care.

Suddenly, there was a slam on the door, as if something in the room had slammed against the iron door, and there was a muffled "bang", and the boy was stunned, and through the glass, he could vaguely see a black shadow locked in the room by a thick iron chain, and the thing let out a sharp roar, and there were strangely long wriggling tentacles on its body.

The shadow tore out the spike holding the chain in place, and slammed it into the iron door again, and the boy could see a claw-like palm slicing through the glass, leaving six black marks. Then a blood-red eye suddenly opened on the side of the glass, and the boy made a close look with the monster through the five-centimeter-thick glass, and the eye stared at him directly, and the boy was so frightened that he did not dare to stay any longer, and ran away wildly, and the iron door behind him slammed, and a beastly howl came from the door.

He didn't know what was in that door, he had never seen anything like it...... But it is conceivable that in every room of Experiment No. 3, there may be an inhuman monster locked up.

The boy ran far away from the quarters before stopping against the wall to catch his breath, the institute was buried with horrible, brutal, bloody secrets, and he didn't want to stay any longer. The boy had a knife in his hand, it was his only weapon, but even a pencil sharpener would turn into a deadly weapon in his hand, and the boy didn't want to kill, and according to the normal plan he wouldn't touch anyone.

But if he really touches someone, he can use this knife to kill his mouth as quickly as possible.

The boy didn't want to kill not because he had compassion, it was simply because time was too tight and he didn't have extra time to spend on things that didn't matter.

He must leave this hell on earth, if he continues to stay here, sooner or later he will enter those iron gates with red signs, be chained to the wall, and become an inhuman monster covered in pus.

The boy turned his head to look around and observed the environment, and behind him was the restaurant, the lights were out, it was pitch black, and the restaurant was empty at this time, and no one would come to the restaurant in the early hours of the morning.

After two more corners, you will get to the elevator, the plan is going very smoothly, nothing goes wrong along the way, at this time the patrol team of the institute should still be patrolling the second floor, and when they come down, they will just enter the elevator and go up, and they will pass by in the elevator shaft.

The boy breathed a sigh of relief, but then his hairs stood on end in an instant!

Suddenly there was a soft "crunch" behind him, and it was the sound of the door of the restaurant being pushed open!

Damn it! How can anyone still wander outside at this time!

He turned and pounced on the person with his mouth covered and pressed against the wall, and then stabbed the other man in the throat.

The other party was obviously frightened stupid a long time ago, and the boy's attack was so fast and fierce that he didn't have time to react at all.

The boy was about to cut the other party's carotid artery, when the force in his hand suddenly struck.

A pair of blank eyes stared at him blankly, and the thin black hair fell down and landed on the boy's hand...... This turned out to be just a child, a little girl of six or seven years old!

The boy was taken aback, he didn't expect a child to suddenly appear at this time, it was early in the morning, and all the children should be locked in the room to sleep...... Why are there still people wandering around?

The hell is ...... He even knew this little girl!
