I don't know if 1551 is intentional or not. The angle on the light screen is very tricky, and it is a close-up of the face.

The face of that thing is eight-point similar to that of humans, but the eyes are more prominent, the complexion is yellowish, his body size is two meters, or even taller, with black scales on his cheeks, and bulging muscles on his body, It is very exaggerated, and his forearm and the outer side of his calf are all black, similar to the dorsal fin of a fish.

Li Yu swallowed, his eyes focused on the monster's fingers.

The nails were pointed and long, hooked inward, and the blood was falling to the ground with the tips of the nails.

Li Yu took a deep breath, his heart jumped to his throat, he knew why there was so much blood in those people's abdomens...

Fuck, it's all the fault of the guy walking the dog without a leash.

Li Yu doesn't like this world, he's not afraid, he just doesn't like it, the thrill is beyond his acceptable range.

1551, "You have no choice."

It paused and prompted, "The security guard has a gun under him."

Li Yu asked the system to turn off the light screen, and in the next second, there was a thud next to his head, accompanied by the vibration caused by the heavy object landing.

The monster didn't take the usual path, and actually jumped over.

Li Yu could feel that he was nearby.

"1551, report his location."

"The target is at nine o'clock on your right, two meters away... No, 0.3 meters away, he stepped over."

Li Yu suddenly opened his eyes, rolled to the left, and jumped up quickly.

Before he could stand still, his eyes suddenly darkened, his body swayed, and the place where the back of his head had been hit hurt badly.

1551 said, "I repaired most of the wound for you, but in order not to arouse suspicion...you know."

Almost at the same time as the system's voice fell, a cold and stiff electronic sound sounded in the laboratory, [Alarm, alarm, except for the AB vents in laboratory 003, all the vents have been closed, and the biochemical attack has entered the countdown, please No. 003. Laboratory staff evacuated immediately. 】

Li Yu, "..."

His eyes swept around, and finally settled in front of a glass wall without any obstacles. This is a single-sided glass.

"1551, is there anyone outside?"

As soon as the words fell, the monster swung over with a claw, and Li Yu lowered his waist and avoided it, twisting and lifting the table next to him.

The opponent didn't play cards according to the rules of the cards, instead of dodging or covering them with his arms, he directly split the table in half with his fingernails.

Inside the loudspeaker, the countdown has begun.

Li Yu knew that in order to prevent the monsters from running out, it was impossible to open the door no matter whether there was someone outside the glass or whether they saw someone alive in the laboratory.

Unless, he can kill the monster before the poison gas is released.

Li Yu turned around and ran, rushed to the body of the security guard, and quickly dragged out the 95 light machine gun.

In the previous training, Zhuang Wei took him to use this one. Compared with the others, it is slightly lighter. It can be single-shot or continuous. However, the latter has slightly higher requirements on the bearing capacity of the shoulders. The advantage is that one One hair after another, there will always be a hit.

Seeing that the prey that was about to arrive would not only resist, but also ran away. The monster was so mad that he jumped up with force under his feet, inserted his claws into the ceiling, and hung upside down on it.

Li Yu carried the weapon, but was unable to pull the trigger standardly.

The monster made a rattling sound, its body dangling in the air, it was looking for the safest and deadliest entry.

Li Yu licked his dry lips, his fingers were stiff, and the countdown above his head had reached 9.

Can't delay any longer.

He buckled hard, turned and ran to the door.

1551 reported in his ear, "He's running fast and dodged."

It’s right to take time and aim without staying in place. Running away can stimulate the opponent’s killing and reduce the opponent’s vigilance.

Li Yu, "How far is he from me?"

1551, "Three meters, two meters..."

When Li Yu arrived at the door, he suddenly stopped moving, turned to face the monster, and when the opponent approached and waved his claws, he moved towards the ugly head and pulled the trigger hard.

The sound of chu chu chu continued, and the smell of gunpowder was strong.

I don't know how long it took, but the sound stopped and the magazine was empty.

There was no pain, indicating that the guy was either dead or injured. Li Yu opened his eyes, and the monster slumped on the ground, becoming a hornet's nest.

At this moment, all his strength was exhausted, and he fell to the ground with a bang, and his body fell straight back.

Before he fell into a coma, he vaguely heard the system say something, and the countdown stopped.

With two beeps, the combination lock of the laboratory door lit up, and the heavy metal door was opened by someone from the outside. Someone came in and carried out the bodies of the young man and the monster.

Li Yu didn't sleep very well this time, and the memory of the original owner always popped up from time to time.

At three o'clock in the morning, he couldn't bear to sit up and didn't plan to go back to sleep.

Outside the ward, the nurse who had been guarding saw the young man wake up, shouting all the way, and the sharp voice finally woke up the doctor on duty who was dozing off.

The doctor's surname was Liu. He took the medical record book, and rushed to the ward with the wind under his feet. At the same time, he took out the walkie-talkie and notified the other staff of the laboratory who were waiting for news in the lobby on the ground floor of the hospital that the patient had woken up.

The pain in the back of the head twitched, but luckily it wasn't too serious. Li Yu raised his hand to touch the bandage on his forehead, got out of bed a little depressed, and went to the bathroom.

The bathroom is white, the ceiling, floor, and walls are pure white.

Li Yu supported the washstand and looked at the mirror. The person inside was young, in his twenties, with naturally curly hair and slightly deep eyes, with blue eyes.

This time it was a mixed race.

Li Yu bent down to wash his face and wake up, but no matter whether he turned left or right, there was not a drop of water in the faucet.

1551 told him, "The water pipe is broken, and there is no water in this area."

Li Yu could only rub his face with his hands and return to the hospital bed.

Shortly after sitting down, the doctor and the colleagues in the laboratory arrived one after another, and they all made an appointment, one by one, and surrounded the hospital bed tightly.

The doctor took a small flashlight and opened the young man's eyelids to examine his eyes, and then his throat.

Finally, he asked him, "Do you have a headache? Do you feel like throwing up?"

"It hurts a little bit, but I don't want to vomit." Li Yu looked around, and unfamiliar faces were smiling at him.

It can be felt that the popularity of the original owner was not bad before.

The doctor wrote down the patient's condition verbatim, went out and called in two nurses, pushed the person to the examination room, and focused on examining the brain.

In the corridor outside the examination room, Li Yu went down to the ground, was helped by the nurse into the examination room, put on disinfectant clothes and shoe covers, lay upright like a piece of wood on the first phase, and was pushed into the MRI.

Taking advantage of closing his eyes, he quickly sorted out the memories left by the original owner.

The original owner is Su He, an assistant researcher who just turned twenty.

This world is different from the previous mission world. From the perspective of technology, the level of civilization should be similar, but the ecological environment of the world is completely devastated.

This is the era of wasteland.

Shortage of resources, degraded vegetation, the once prosperous city has become a ruin covered by wind and sand, in addition to the environment is no longer suitable for survival, human beings have an additional natural enemy, a type of monster collectively called xenogeneic.

In order to avoid those bloodthirsty monsters, humans mobilized a lot of manpower, financial resources, and materials to build underground fortresses, and in just half a year, they moved their living areas underground.

In the past, the ruler of the world who walked and ran on the ground on two legs has suddenly become a weakling who can only hide in the ground, seek shelter in a fortress, and must not be captured.

With a beep, the inspection is over.

Li Yu's thoughts were interrupted, he opened his eyes and sat up.

The doctor came out of the operating room and instructed, "Don't run around, take a rest on the stool in the corridor, and come out immediately."

Li Yu nodded, his mental state was not bad, he declined the nurse's kindness to help, walked out alone, and sat on the bench.

At the end of the corridor, someone came by.

The man was tall and thin, with striking blonde hair on his head.

Li Yu dug out the information of this person from memory, Delson, a 37-year-old middle-aged bachelor, the chief researcher of the institute.

Delser is a research maniac. In his concept, he can do any experiments, including animal experiments and human experiments, in order to find a way to kill the alien species.

Speaking of which, the appearance of xenogeneic species was entirely made by some scientists themselves.

Forty years ago, humans discovered a legendary creature, the mermaid, in the deep seas of the polar glaciers.

They are beautiful, elegant, and terribly aggressive at the same time.

New things always have a mysterious temptation, which can easily arouse people's fanatical desire to find out. After catching the first mermaid, various countries sent the top biological scientists to form a research team to carry out in-depth and most detailed research on it. Research.

Surprisingly, the cell aging rate of the new species is four times slower than that of humans. As long as the genetic code of the mermaid is unlocked, the human lifespan can be extended from 100 to 400 years old.

There are too many beautiful things in the world, and everyone wants to live a few more days and enjoy more.

The polar glaciers covered by ice and snow were gradually embellished with blood donations. In order to escape the fishing, the mermaid group launched a fierce and long-term war with human beings, and finally lost to the cutting-edge and violent weapons of human beings.

They were forced to migrate and fled everywhere. Some were favored by the goddess of luck and escaped danger and hid in the depths of other seas; , repeating the painful experiment day after day.

In July 20xx, the five-year-long experiment finally came to fruition. Mermaid serum worked on mice.

After the thin little guy was injected with serum, his body size, speed, and aggression all changed dramatically.

Laboratories in the United City of various countries began to openly recruit volunteers to conduct human experiments, and within three months, it was determined that the mermaid serum can quickly heal human wounds, slow down aging, and even strengthen the hardness and flexibility of human muscles.

Not only that, but also the function of human organs can be improved to a certain extent.

At the press conference held, the spokesperson confidently told everyone that the mermaid serum can restore the youth and health of an 80-year-old man.

This major breakthrough sent all mankind into a carnival.

The wealthy people who were waiting and watching have donated money, hoping that the research can be completed as soon as possible and put into production, and even those in power contacted the laboratory privately, hoping to become the beneficiary as soon as possible.

However, shortly after that, the volunteers who volunteered for the money had their bodies mutated.

Their eyes, teeth, bones, muscles, limbs, and even temperament... everything changed.

The most terrifying thing is that a small number of them still retain their normal IQ.

This is undoubtedly a new generation of biological weapons, and it is an extremely valuable war resource in the hands of any country.

On the contrary, these new species that have been transformed are also quite dangerous. Once they get out of control, their bloodthirsty nature will drive them to kill them. Coupled with their super recovery ability, once there is a mistake, as a Humans who control them will be reduced to prey under their sharp claws in an instant.

So soon, the countries participating in the experiment were divided into two parts because of different ideas, the opposition and the support.

After a period of competition, the minority finally obeyed the majority, and after careful risk assessment, countries decided to start the destruction plan.

However, on the night before the destruction plan was implemented, an accident happened.

A thief was caught in the joint laboratory. He tried to smuggle 60 serums hidden in his clothes at night and hand them over to the contact person in the opposition country who was waiting at the exit of laboratory B.

Just when he was still a dozen steps away from reaching the exit, the unlucky security guards found him.

While fleeing in panic, the serum fell out of his clothes and shattered.

The pale golden viscous liquid reacts with the air, boils rapidly, evaporates, and dissolves into the air.

During the original experiment, considering the living environment and the mermaid's own body temperature, the scientists drew every tube of blood from the mermaid's body and separated every drop of serum, all in a low temperature and sterile state.

No one knows what will happen when the serum comes into contact with the air or high temperature, not to mention that the air is invisible, odorless, and pervasive. You can block the laboratory and prohibit people from entering and leaving, but you cannot prevent the air mixed with serum vapor from spreading and spreading.

In order not to cause panic and be held accountable from above, the on-duty person in charge of the laboratory that day ordered all the staff that night to keep their mouths shut, otherwise they would be held accountable and no one would be able to escape.

Less than two weeks after the incident, an outbreak occurred in the town closest to the laboratory, and some townspeople suffered from vomiting and diarrhea.

Because the weather was hot at that time, and went to the hospital to find out the problem, everyone thought that they had eaten something bad, but they didn’t take it to heart. The trip that should travel, the child who should have a child, and life did not change because of this short episode. .

Gradually, the epidemic began to spread in the surrounding small towns, and the top finally began to pay attention to this problem, sending professional medical teams to various places for treatment and conducting epidemic research at the same time.

The study found that this outbreak is transmitted through the respiratory tract, and the incubation time is directly related to the physical fitness of individuals.

Some symptoms appear in half a month, and some are found in a month or even two months.

The rapid development of the epidemic is almost like a prairie prairie. In order to prevent the spread of the epidemic, cities with infected people have to adopt a city-wide blockade, and every person entering and leaving must undergo strict quarantine.

Those infected were sent to hospitals for isolation.

Some families can't bear the suffering of their children or relatives. They hide their illnesses and do not report them. They feel that they can take good care of others, but they don't want that one day, the family members they take care of and protect will become violent and bloodthirsty monsters.

The initial riot occurred in the isolation area of ​​the hospital. There were more than 20,000 patients in hospitals in several cities participating in the control of the epidemic. For some unknown reason, these people all mutated overnight.

They broke through the custody of the hospital, destroyed and killed without reason, and turned the good city into a battlefield of killing.

Due to the particularity of the infection route and incubation period, many people escaped isolation.

This part of the people wandered around peacefully, unaware that there was a time bomb hidden in their bodies.

By the time they were found, it was too late.

These people and the mutants who were first infected should work together to destroy the city.

At that time, scientists had not yet developed a mask that could effectively isolate and purify the air. People who could not evacuate could only hide at home, or be found by mutants and become new infected people waiting to mutate.

Or, become food in the mouths of mutants.

Li Yu couldn't help sighing, selfishness, selfishness, ignorance, and ruined the world.

All these things in my mind were all told by the original owner listening to the teacher. Later, under the influence of the riot, fires and explosions occurred in the nuclear power plant and nuclear research center, the environment was completely polluted, and the vegetation was rapidly degraded. Within a few years, the city, It was gradually submerged by the sandy soil extending from the continental margin.

"Assistant Su, are you okay?"

The soft greeting interrupted Li Yu's thoughts. He raised his head and met a pair of light brown eyes.

Those eyes, hidden behind the lenses, glowed with excitement.

In the last ten seconds of the youth, Dylan was amazed by the fighting power that broke out. He is very curious now, what the hell is hiding from him, who has just been under his command for two weeks, and who is always silent at his command.

"I'm fine, Mr. Delson." After lying down, Li Yu's voice was slightly hoarse, "Sir, what are you doing here?"

"I heard that you are awake, come and take a look." A gentle smile hung on the corner of Delson's lips, like a kind elder.

That's why Li Yu became more and more terrified.

Everyone has both good and bad faces, but like Delson, there is such a big gap between the experiment and the experiment, it should be called a perversion.

"Why don't you talk, it's uncomfortable?" Dellson frowned and glanced around, "Where's the nurse who sent you here?"

"They were waiting for me outside the corridor of the examination room."

Li Yu endured the pain in his head and comforted the professor who had begun to be impatient, "Mr. Delson, I asked them to wait for me outside."

Delson scrutinized the youth carefully.

Because of the injury, the young man's blue eyes seemed to have lost their lustre, dull and dull, and the already white skin was a little more disgusting sickness.

"Since that's the case, I'm relieved." Daleson smiled slightly, "You know, the laboratory is very tight, and I look forward to your early recovery."

Seeing someone want to leave, Li Yu pretended to be weak and stood up against the wall, as if he was going to send the professor away.

Delson didn't want to stay with the sick person for too long, and declined, "Don't send me."

After talking about work, he paused and continued, "By the way, about work, I have told Zhang Zefeng to ask him to come to you in the afternoon to take over."

Li Yu's face was pale, and even nodding seemed labored, he took a step forward. Thinking of Delson's light brown eyes, after hesitating for a moment, his body swayed left and right, and fell softly in the direction of Delson.

Delson subconsciously reached out to hold the young man's arm and stepped back half a step.

Li Yu encouraged him to stand firm and said weakly, "Thank you, Professor."

Delson let go, took out a handkerchief from his pocket and wiped his hands in front of his subordinates.

"Okay." Li Yu stood against the wall until the man left before taking two steps back and sitting back on the bench.

He stared at the empty corridor for a moment and asked, "1551, is there any response?"

1551, "No, Delser is not a target."

Li Yu breathed a sigh of relief, but fortunately it wasn't, if it was, the task in this world still didn't know how to proceed.

Dalson is a person with a different appearance, inhumane, and he has no idea how much blood he has on his hands. He can no longer be called a human being. He is an out-and-out devil.
