Su Yuan didn't know what Lei Chengji and Han Jingguo were calling him for, and they were in the teaching building, which was really strange.

Follow Deng Dong to the door of the teaching building.

Deng Dong didn't go in, but opened the door for Su Yuan: "Doctor Su, turn right and walk until you reach the last classroom." ”

"You're not going in?" Su Yuan was surprised.

"I still have to contact Captain Lin, besides, the matter here has nothing to do with me." Deng Dong said it very directly.

Su Yuan smiled bitterly, yes, even if Deng Dong followed the past, it was useless, Deng Dong couldn't understand the discussion between their doctors, and it was in vain to go.

Entering the teaching building, Su Yuan came to the door of the last classroom in the corridor as Deng Dong said.

Through the glass on the door, he saw two men in hazmat suits discussing something inside.

Knock knock.

Su Yuan knocked on the door.

After hearing the voice, the two people inside said hello to Su Yuan, and then beckoned him to open the door directly.

Su Yuan pushed the door and found that this classroom was a multi-room classroom, simply put, there were partitions in this classroom, which divided the entire classroom into several pieces.

"Here, put on your protective suit." Lei Chengji pointed to another piece of protective clothing piled up on the side and said.

Su Yuan didn't have any doubts, began to put on protective clothing, and asked by the way, "What are we doing here?" ”

Lei Chengji smiled mysteriously: "You'll know later." ”

Su Yuan glanced at the remaining space separated by the partition, and already had a guess in his heart, but he always felt a little incredible.

After putting on the protective suit rigorously and confirming that there was no problem twice, he said, "I'm fine." ”

"Let's go, let's go inside." Lei Chengji opened the door on the partition in front of him as he spoke.

The protective clothing on Su Yuan's three of them was armed from head to toe, and there were almost no exposed parts.

After stepping into the partition room and seeing the contents inside, Su Yuan was surprised.

He was surprised not because of what he saw in front of him, but because he was surprised why they were so bold that they dared to catch the zombies that were alive and could still move here?

Crazy!

What if something happens?

At this moment, in front of Su Yuan.

There is an iron bed, I don't know where it came from, on top of the iron bed, there is a zombie tied.

The zombie's hands and feet were stretched apart, and there were nylon ropes on his waist, chest, and knees, which were very tight, which also caused the zombie to be unable to move.

Su Yuan approached and found that this zombie had no jaw, and the jaw seemed to have been specially cut off.

In this way, it will not be able to bite.

"Why, zombies are here?" Su Yuan had already guessed it before, but he still couldn't understand it.

Lei Chengji looked at him and said, "What else, of course, it's for research." ”

Han Jingguo also said: "We don't know much about zombies now, and this is the first time that we have captured living zombies for research." Before you arrived, we had already performed an autopsy on the dead zombies. ”

Su Yuan was surprised: "Is there any result?" ”

Han Jingguo shook his head: "No, dead zombies are no different from ordinary dead people, just like the anatomy class before." ”

Su Yuan's eyes showed helplessness.

Lei Chengji laughed and said: "It's because there was no result before, no, I finally got a live zombie over, and this time there should be some results." Xiao Su, you can help us do it, and by the way, pay attention to the condition of this zombie, but this guy's jaw is gone, but he is still a little afraid. ”

"Understood." Su Yuan came to Lei Chengji's side, sorted out the dissecting instruments, and asked, "Where to start?" ”

Lei Chengji frowned, this alone is a bit difficult.

Han Jingguo said: "Why don't you test his vital signs first?" ”

"No need, these are all zombies, where are the vital signs?" Lei Chengji said speechlessly.

Han Jingguo said: "However, I want to try, but I don't know where to start anyway." ”

Lei Chengji was helpless, "Okay, then let's try." ”

In addition to brain activity, there are generally four indicators of vital signs.

Respiration, heartbeat, body temperature, blood pressure.

In fact, all you need to do is measure your breath and heartbeat.

Lei Chengji cautiously stretched his hand under the zombie's nose, wanting to probe its snort.

But halfway through, he was stopped by Han Jingguo and didn't ask, "What are you doing?" ”

"Take your breath." Lei Chengji said.

Han Jingguo was speechless, the general breathing test is to see a person's chest ups and downs, and no doctor will try the nose.

However, Lei Chengji did this for a reason, and he hurriedly explained: "I don't see any ups and downs in this guy's chest, so I'll try snorting, in case there is any breath." ”

Han Jingguo came back to his senses and took a closer look at the zombie's chest, which did not rise and fall, "Then you can't use your hands!" ”

So he directly pulled some cotton from the cotton ball on the side and threw it under the zombie's nose, but there was no movement at all, indicating that the zombie was not breathing.

Lei Chengji smiled awkwardly and hurriedly crossed the topic: "Hurry up, look at the heartbeat." ”

Immediately, Han Jingguo picked up the stethoscope on the side, opened the cover on his head, put the earbuds into his ears, and put the earbuds on the zombie's chest. ”

Lei Chengji and Su Yuan were both taken aback.

"What's wrong, what's wrong? What did you hear? ”

Lei Chengji was so frightened by the other party that he began to panic, and he couldn't help but take a few steps back.

Su Yuan was also puzzled, what did he hear? So excited.

The corners of Han Jingguo's mouth twitched twice, stared at the zombie, and said in fear: "It, it has a heartbeat!" ”

Lei Chengji was speechless: "Hey, hey, old Han, you're too much, where is the heartbeat of a zombie!" You're too scary. ”

Han Jingguo swallowed his saliva: "I didn't lie to you!" Really, really have a heartbeat, don't believe you listen to it yourself! ”

Lei Chengji saw the other party's serious appearance, and asked in surprise: "You really didn't deceive people?" ”

Han Jingguo rolled his eyes and said eagerly: "Do I need to lie to you at such a time?" I'm still nervous or sick! ”

"Maybe you're just getting nervous." Lei Chengji teased.

Han Jingguo's expression on his face: "......"

"I'll listen." Su Yuan took out the stethoscope and put it on his ear, and then put the earhead on the zombie's chest.

Suddenly, a heartbeat sound came from the zombie's chest, and the heartbeat sound was indeed there, but it was very long, and it took five or six seconds to beat.

Lei Chengji saw Su Yuan's solemn face and asked, "Don't tell me, it's really heartbeat!" ”

Su Yuan took off the stethoscope and nodded: "Indeed, once in five or six seconds." But there really wasn't any movement of breathing. ”

"Damn!" Lei Chengji scolded, "What's the situation! These are all zombies, how can they really have a heartbeat! ”

Su Yuan handed the stethoscope to Lei Chengji and asked him to listen to it himself, then looked at Han Jingguo and said, "Doctor Han, when the zombies just broke out before, I checked those who had just become zombies and found that they didn't have a heartbeat, and it was an accident that this zombie had a heartbeat. ”

Han Jingguo thought about it carefully, shook his head and said: "No, no, no, it's all wrong, we all thought wrong at the beginning!" ”
