Liu Xin walked to the stairs of the underground passage, pricking up his ears to hear something through the heavy walls.

"There's no sound." Feng Weitao said in a deep voice, his eyes looking around as if they hadn't opened them.

Zhang Pengtao's words suddenly made the air in the entire underground air-raid shelter solidify, but Xu Wen and Zhou Xi were still like fat people, and they didn't hear any sound. Liu Xin half-squatted at the staircase and looked at Zhang Pengtao who was standing aside, as if wondering if he had heard it wrong.

"The voice didn't come from the ground."

Zhang Pengtao's words also just reminded the four people that even if the ground and basement are connected, it is impossible to hear any sound from such a thick cement.

Xu Wen walked to the wall and knocked on the surface, and as soon as Zhou Xi walked next to him, he was frightened and stopped in place by the sound coming from the wall.

Cluck......

Xu Wen responded to the wall he had been knocking on, but before he could continue to knock on the side, there was a frantic crashing sound.

Everyone took several steps back, and no one knew what was behind the wall. The sound of the crash was still coming through everyone's cochlea endlessly, so rapid and so terrifying.

"What the hell is over there?" Zhou Xi didn't know when to walk to Liu Xin's side, and her slender hands had already tightly grasped Liu Xin's arm, as if she could be guaranteed as soon as something happened.

Liu Xin's expression suddenly tightened, and his heart was beating rapidly with every impact.

"Liu Xin, are you sure it's safe here?"

Xu Wen's question made Liu Xin speechless, being able to make such a strong sound is not something that a body can do.

"I've looked around, it's all walls. Unless the opposite one can directly break through this wall. ”

Zhang Pengtao stood in the corner and was already inspecting the entire air-raid shelter while everyone was in a daze, and continued to take the protective clothing in his hand and said: "This is not an air-raid shelter, this is a place to store items." But I've observed, and the ground to the basement concrete is thick enough to withstand the bombardment. ”

Feng Weitao looked at Liu Xin, who was still in a daze, and was about to step forward to comfort him, but was stopped by Liu Xin. After all, even a well-trained police officer can't resist such a thing. Zhou Xi watched this scene, and was also glad in his heart that there was another well-trained soldier by his side.

As time passed, the walls became silent. None of the five people present believed that there was a living person behind the wall, after all, anyone in Andong City could be the one who was infected.

The five of them sat on the ground in a circle and began to study the [Brain Death Research Plan] that was fastened together with paper clips and was more than ten pages long

"It's part of the document, but how did it end up in the police archives?" Zhang Pengtao's focus has always been this.

Zhou Xi and Xu Wen looked at each other, but they couldn't look at the words. After all, those bloody scenes have been seen all the time these days, and I never wanted to hide in the basement and be disgusted by the files of the research plan.

"Xu Xiong, the mayor, built a research base in Andong City without the knowledge of Yancheng, no wonder there was a mountain fire some time ago."

Feng Weitao ate the canned food in his hand while staring at the picture report in front of him.

"Come and take a look at this." Liu Xin seemed to have discovered something, and held up the dense documents printed out of 4A paper in his hand to the candlelight.

[6 months ago......]

"Doctor Liu, something happened."

The nurse rushed into Dr. Liu's office in a hurry, and her panicked expression seemed to tell him that another experimenter was crazy. Cold eyes were fixed on the nurse's trembling lips, still waiting for what she was going to say next.

"Patient No. 1, Patient No. 1, do you remember?"

"Patient One?" Dr. Liu stood up suddenly, blurted out a questioning tone, and hurried out of the office.

After the construction of the peak laboratory was completed, Patient 1 was the first 23-year-old male to attempt to resurrect from brain death. During the week of continuous delivery of the drug, there was no significant effect, and there were even several cardiac arrests. So under the persuasion of the leader, he gave up on this patient.

The nurse trotted all the way to lead the way to the laboratory operating room. Patient No. 1, who had already left the laboratory, was lying on the pale hospital bed with a white cloth covering his entire body.

Without saying a word, Dr. Liu lifted the white cloth and saw that the patient was much older than before. Before the onlookers could react, the sudden smell of corpse decay rushed into their noses, instantly causing everyone present to vomit food residues all over the floor.

The accompanying nurse stood beside Dr. Liu in no surprise, and the fear in her heart slowly spread to her whole body with a little observation.

The patient's bony figure was unaware of what had been bitten, covered with scabbed wounds and tooth marks that were still leaking pus. Something in the scalp is clearly visible, moving slowly and slowly over the entire top of the head.

"Give it to me." The nurse ran to the doctor, who was still bending over and didn't vomit clean, snatched the patient's file and walked to Dr. Liu. With watery eyes, he carefully looked at the words on the file, picked out the key information, and began to report the patient's condition.

"On the fifth day after leaving the laboratory, the patient developed symptoms such as high fever and intracranial hemorrhage. After three days, the patient was awake, in good spirits, and gradually regained his appetite within a week. Two weeks later, the patient developed irregular convulsions, the cause of which could not be identified. A month later......"

Without waiting for the nurse to finish, Dr. Liu stared at the patient and said, "The patient has mental loss phenomena such as madness and biting......

Dr. Liu's frowning brow seemed to have established his own conjecture in his heart, and the same phenomenon had occurred in patient No. 33 half a year ago. The drug treatment in this experiment simply does not meet the standard for treating brain death.

"What went wrong...... Dr. Liu had gone through the recipe of the drug dozens of times in his mind, but he couldn't figure out the reason for the failure.

"Dr. Liu, the patient is awake."

The nurse's reminder made Dr. Liu, who was still in a daze, suddenly come back to his senses. The patient, who had opened his eyes and lost expression, kept looking at him, his lips slightly open as if he wanted to say something, but he couldn't speak.

"I'm sorry ......"

Before Dr. Liu could speak, the nurse bowed and apologized. The patient was calm, as if he had already been tortured and showed a casual attitude towards life. Looking at the two people in front of him, he shook his head slightly, and slowly closed his eyes.

"Xiaozhou, help him euthanize."

Dr. Liu could no longer accept the reality that the torture and collapse of the No. 1 patient in front of him due to the drug research accident would also leave a layer of haze in his professional career.

The nurse looked at the arm of Patient No. 1, which was still printed with the words "Patient No. 1", sighed slowly, and left the operating room with Dr. Liu's pace.

Back in the office, Dr. Liu looked up just in time to see the nurse sorting out her bookshelves.

This girl has been following her for almost a year, but she hasn't looked at her carefully.

"Your name is Sun Yan, right?"

When Sun Yan heard Dr. Liu call her name for the first time, she was suddenly a little unaccustomed, and her hands for arranging the bookshelves stopped in mid-air.

"Yes, Dr. Liu." Sun Yan hurriedly turned her head, pointed to the nurse card hanging on her chest, and looked at Dr. Liu happily as if she had won some award.

Dr. Liu was a little helpless, and pointed to the name plate on his desk, on which two big characters were written Liu Shuo. Both of them were introducing each other for the first time, pointing to their own names for a long time.

I saw Sun Yan's watery eyes, which were already tired and full of red bloodshots, and her fleshy face was full of collagen. If you don't look closely, you don't know that the nurse who has been following you for so long is a little cute.

Today's Sun Yan is full of Liu Shuo's face with only one expression, and her decisive personality was deeply attracted on the first day she came to the peak laboratory.

"Quick! Hold him down. ”

Sun Yan turned around and saw a group of people piling up at the end of the corridor, rushing to knock down something.

"Damn, these teeth are too sharp."

"What are you doing, don't be so noisy." Sun Yan didn't want to care what they were grabbing, after all, this Liu Shuo was still in the office and didn't want the surrounding environment to be too noisy.

"Ran away......"

Sun Yan shouted from everyone at the end of the corridor and watched Patient No. 1, who had no strength, get up from the crowd and flee in the other direction......
