When J was on duty, Li Li would make a round in the middle of the night, which had become a habit.

Moonlight is like water. Even though it's only a crescent moon, it's still so bright. It seems to shine into people's eyes. Li Li walked out of the dormitory door and couldn't help squinting his eyes.

Suddenly, a black shadow appeared in the sky, flying in front of the crescent moon, and at the moment when the light passed through the crescent, Li Li clearly saw that the black shadow flapped its wings.

Li Li was stunned.

Is that kind of height, that kind of flying thing, still a bird?

The black shadow passed through the crooked crescent moon in the blink of an eye, disappeared into the darkness, and disappeared from Li Li's sight.

The visual height is more than 1,000 meters, and the visual length is ...... The wings are spread out for more than a meter, and the actual length is ...... Li Li was taken aback, a little doubtful that he was dazzled just now.

But he knew he wasn't dazzled. His eyesight was much better than it had been a week ago, not to mention that he wouldn't have been dazzled a week ago.

Li Li patrolled the night sky again, and he couldn't see anything except the bright moon and a few stars.

He withdrew his gaze and made his routine rounds.

It was the same as every day, but the feeling of uneasiness in his heart became stronger and stronger, as if something he had noticed but was being ignored.

Suddenly, a hurried voice came from the walkie-talkie on the shoulder: Negative second floor alarm of the research institute! The infected person on the second floor of the research institute has hijacked the doctor!

Li Li was startled, and while saying into the walkie-talkie, "I'll go over right away," he had already run towards the gate of the research institute.

"Captain Li, there is an infected person in the cell on the second floor of the negative who broke the fence and held the doctor hostage. Now the first-level security has been opened, and all passages of the institute are closed. The attendant in the monitoring room at the institute continued.

"Keep on guard." Li Li commanded.

The institute itself has arranged guards and security guards, but there is no danger and the need for doctors, only the monitoring room is on duty, and the outside world enters the institute, theoretically only Li Li and he bring in.

Swipe the card at the door, iris, and at the same time confirm in the monitoring room that one of the three is indispensable under the first-level alarm, Li Li entered the institute and went to the monitoring room first.

In the monitoring room, images of all parts of the research institute continued to appear separately, and at the same time, the people in the monitoring room began to explain what had happened.

Since the day before, the infected person has added a night meal, around 12 o'clock in the middle of the night. At first, it was normal, but when it was delivered to Infected Person 19, the infected person suddenly broke the fence and directly reached out a hand and grabbed the neck of the food delivery doctor.

Judging from the surveillance, at the fence that Li Li was familiar with, a male doctor leaned on the fence in an extremely awkward posture, his neck was twisted by one hand in the fence, and he barely stood by holding the fence behind him with both hands.

The man in the fence didn't care about the camera, his eyes flashed fiercely, and the people next door and even in the entire corridor fence were all hanging the fence frantically, shouting.

"How can he be so strong that the steel fence can be bent?" Li Li frowned.

The person in the monitoring room shook his head and played back the monitoring again, and it can be clearly seen from the screen that in an instant, the person's hands bent the fence.

No one answered. To what extent the infected have mutated is known only to the researchers here.

Li Li didn't wait for an answer, he made a gesture, and the picture of cell 19 was enlarged.

The infected grinned, one hand pinching the doctor's neck like an eagle catching a chicken, and the other dancing triumphantly. The kidnapping doctor tilted his head and looked pained.

Li Li couldn't help but think of what Cheng Jiayi had done to him today, and his throat was a little itchy.

With the same action, the expression on Cheng Jiayi's face was resolute, but this man was hideous.

"I'll go take a look." Li Li commanded.

The research institute is a double-edged sword, both a place where infections are researched and a place where big problems can be caused. He was amazed that the infected were able to bend the iron fence.

But how did it break today? Professor Marin had been admitted for surgery the night before, and this kind of problem occurred the next day?

Coincidence or necessity? Researchers really don't know that the strength of the infected is increasing?

Li Li's footsteps slowed down, and he once again remembered Cheng Jiayi's shot.

If the strength of the infected has increased......

Li Li entered the second floor and greeted him as a professor.

"Hello Professor Yi, why do your experimenters have so much strength?" As soon as Li Li entered, he asked straight to the point.

The professor still made a gesture of please and led Li Li to the office, and the computer on the desktop of her office was also turned on, and the picture on it was the same as that in the monitoring room.

Li Li frowned and looked at Professor Still.

"We have this permission, after all, it's our test subject." Professor Still briefly explained, "We have always suspected that there is a possibility of secondary evolution of infected people. Now it's probably evolving. ”

"Second evolution?" Li Li said in surprise.

"The data gap in the trial is also very large, and the time is short, so it is just a suspicion." Still the professor's face showed some weariness.

Li Li frowned and pointed at the noisy picture of the computer: "No sedative? Anaesthetic? ”

Professor Still shook his head: "These single rooms are not enclosed, and the whole space is sedated, and the weight is too large. It is also difficult to clear after the fact. And ordinary sedatives do not work for them, and even provoke their ...... Potential. ”

Li Li said keenly: "What potential? ”

The professor was silent for a moment before he said, "The potential of the human body, the potential of mutation, or the potential that we don't know yet. ”

Li Li was keenly aware that Professor Yu was not telling the full truth.

Li Li looked at the screen, didn't rush in, and continued to ask: "If these infected people all evolve twice, these fences ......"

Li Li looked up and observed Professor Still's expression: "What should I do if I can't stop it?" ”

The professor was still expressionless: "If this situation really occurs, it's Captain Li's business." ”

Li Li still looked at Professor Still, and Professor Still finally looked away from his eyes that were staring at the screen and looked at Li Li.

"Can I ask Professor Yi what the mutations will appear in?" Li Lidao.

"Team Lee violated the rules." Still the professor was still expressionless.

Li Li nodded, pointed to the screen of the computer screen and said, "Yes, but I'm going to go in here later, I don't want to face ignorance." ”

In the picture, the doctor seems to be exhausted, his body is sliding, but the hand holding his neck does not relax in the slightest. The doctor can be seen gasping for breath with his mouth open.

Li Li didn't wait for Professor Still's answer, he cursed in his heart, turned around and pressed the walkie-talkie as he walked: "I'll go in and prepare to open the passage." ”

"Team Lee." Professor Still called out to Li Li.

Li Li stood down and turned around.

"Physical strength and intelligence may be strengthened, and after being stimulated, it may suddenly explode, and the physical strength will increase instantly."

Li Li looked at it again before nodding and saying, "Thank you." ”
