Zhen Zhen pulled out the vein needle on Nan Zhiqiao's arm and reached out to touch Nan Zhiqiao's cheek.

Alex stood beside Zhen Zhen, staring at Nan Zhiqiao in the glass coffin, he was distracted for two seconds, followed by his reaction, and asked, "Sister Zhen Zhen, how is he?"

"At present, it is not life-threatening, but he is in a coma, and the specific situation will be known after going back for examination. ”

"How do you get him out?" Alex looked back at the dark river outside the small cave, the current was so fast that two people with good water skills could come in quietly, but it was impossible to swim out with another unconscious person.

Thinking of the speedboat that passed by just now, it was the best way to go out by speedboat, but there were four guards with weapons around the speedboat, and there were six experimenters, and if you want to grab the speedboat, you have to deal with them first.

Zhen Zhen and Alex thought of this solution at the same time, and Zhen Zhen asked, "Alex, how are you doing?"

"Hmm......" Alex rubbed his wrist, "it's no problem to deal with two strong men at the same time." ”

"Well, let's split up. ”

Vera devises a plan of action: Alex makes noise on the side of the cave to attract the guards, and Vera swims back down the dark river to the small biochemical lab, taking advantage of the fact that the guards are lured away to subdue the experimenters.

According to Zhenzhen's plan, Alex hides in the middle of the glass coffin in the Great Cave, and Zhenzhen follows the current of the dark river back to the biochemistry laboratory.

Soon heard the sound of "dong dong dong" from the side of the big karst cave, and the four guards guarding the perimeter of the biochemical laboratory immediately became alert.

One of the leading guards instructed the other two, "You two go and see if any of the test subjects have woken up?" ”

Two tall guards led the order, and with an experimenter in a white coat, took a bottle of yellow potion and walked towards the direction of the big cave.

Zhen Zhen took the opportunity to go ashore and quietly used the white bracelet to silently solve the two remaining gun-wielding guards, while the remaining five experimenters were busy with their own work.

Five people can't be subdued at the same time, and it would be bad if something made to alarm the others.

While thinking about it, Zhen Zhen caught a glimpse of a large bottle of ether in the corner of the laboratory table, and suddenly thought of an idea.

Vera quietly took the ether off the bench, opened the lid, and poured the liquid on the floor.

Ether has strong volatility and is an anesthetic, which is often used in animal experiments, and Zhen Zhen is familiar with its role.

After pouring all the ether on the ground, Zhen Zhen dived back into the dark river, her head submerged, and after a while, several experimenters were fumigated by the ether that volatilized in the air.

"Bang!" a loud gunshot rang out from the cave.

"Alex!" Worried about Alex's situation, Vera quickly swam from the Dark River to the Great Cave.

Alex was standing in the middle of the rows of glass coffins, two guards fell to the ground, one was shot in the head, one had his neck broken, and a white lab coat was kneeling and begging for mercy.

Alex raised his hand to stun the experimenter, but Zhen Zhen stopped in time: "Stop, I have something to ask him." ”

Alex didn't expect Zhen Zhen to come back so soon, and hurriedly asked, "That's the solution?"

"Well, it's all settled. ”

Zhen Zhen looked down at the experimenter kneeling on the ground, he was a thin man in his forties, thick black-rimmed glasses covering most of his face, and his stubble pressed against his chin, as if he hadn't washed in days.

The man trembled with fright, and kept repeating: "I was captured, don't kill me, don't kill me......"

Zhen Zhen asked in a low voice, "How many people are in this cave laboratory?"

"One hundred and sixty-eight. The man replied simply.

Zhen Zhen and Alex were shocked, there were so many people! The two of them had only cleaned up ten of them together.

Zhen Zhen reacted that the "one hundred and sixty-eight" that the man said should include the test subjects in the glass coffin.

Zhen Zhen asked again, "How many staff are there?"

"Six experimenters, four guards. The man followed up and explained, "Of the six experimenters, Sam and Tommy are the leaders, the other four were captured, and so am I, and the four guards only listen to Sam. ”

The ten people who were subdued just now were all the staff of the entire cave laboratory.

Alex pointed a gun at the man's head and asked, "What are you doing here?"

The man didn't dare to move, and replied in a trembling voice: "The experimental subjects here have been injected with a certain pathogen, and then treated with different drugs to observe the effect of the treatment. ”

"What pathogen?"

"I don't know, it's a secret experiment, and the people who captured us won't let us touch it, and I speculate it's some kind of virus. ”

"Where did the test subjects come from?"

"I don't know, I've been in for more than four months, and the test subjects are updated every day, the dead test subjects are disposed of, and new test subjects are constantly being sent in. ”

Alex felt a chill and asked, "How many test subjects did you use?"

"Since I came here, more than two hundred test subjects have died, and one hundred and fifty-eight are still alive. ”

Ye Zhenzhen pulled the man up, dragged him to Nan Zhiqiao's glass coffin, and asked, "When was he sent in?"

"More than half a month ago, I knew him, he is Nan Zhiqiao, the heir of the Nanmu Group. ”

"He was also injected with pathogens?"

The man hurriedly shook his head, "No, he is the only one who has not been injected with the pathogen." ”

"Why?"

The man explained," Believe it or not, Mr. Xiao Nan once saved my life, I am a researcher of a biological company under the Nanmu Group, my name is Li Hong, four months ago, the company organized us to go on an outing, the bus rushed into the canyon, fell into the turbulence in the canyon, and when I woke up, I found that I had been caught here, and there were three other colleagues who were arrested together, all of whom were researchers of the company, we escaped several times and were caught back, and were beaten violently, the guards watched to death, we have been trying to find another opportunity to escape, until we saw Mr. Xiao Nan was caught in. ”

The man paused and continued: "I know that there must be a big conspiracy here, so when Sam asked me to inject Mr. Xiao Nan with pathogens, I secretly replaced the reagents with pathogens with normal saline, which is harmless to the body, and then in the next experiments, I falsified the test data to make Mr. Xiao Nan look like he was cured." ”

Ye Zhenzhen remembered that four months ago, there was a car accident in a vaccine company under Nanmu Group, a bus carrying company employees on an outing rushed into the canyon, and when it was salvaged, four people were missing, and all four of them were vaccine research workers.

It seems that the man named Li Hong in front of him is right.
