This time, the police invested a lot of police resources and carried out a mountain search operation, focusing on the burial site and expanding the search outward.

Public security, patrol special police, firefighting, and rescue carried out joint operations, and police dogs and various detection equipment were also on the battlefield.

By dark, police had found eight bodies, all of which had very different degrees of decomposition.

The search continued, the Jing'an City Criminal Investigation Detachment returned to deal with the case first, and the forensic department also launched an autopsy.

In the autopsy room of the forensic department, everyone was busy, Lu Ke directly pushed the door in, looked around, and walked straight to Jiang Xiran, who was sorting out the autopsy report at the table, and asked, "Is the cause of death determined?" ”

Jiang Xiran raised his head, glanced at Lu Ke, and shook his head: "No." ”

Lu Ke was a little dazed, looking at her in a daze, his eyes falling on the incomplete autopsy report.

Jiang Xiran was a little tired, and said lightly: "Judging from the current autopsy situation, no obvious external injuries were found for all the deceased, and there were no obvious traces of homicide. However, judging from the bone age, the deceased are all seventy or eighty years old, and it is very likely that they are people in nursing homes. They are likely to die suddenly, and there is a high probability of illness, and relevant testing is still ongoing. ”

Although Jiang Xiran did not give an accurate cause of death, Lu Ke had already made a judgment in his heart at this time, and the cause of death of these people was very likely to be the same as Sun Jinyu, who were poisoned by drugs.

Lu Ke pondered for a moment, then asked, "What about the time of death?" ”

Jiang Xiran blinked: "As for the more accurate determination of the time of death, I still need to go to the scene and find some samples related to temperature, humidity and biological environment." But what is certain at the moment is that the longest time to die should be about two years. ”

"Two years ......," Lu Ke muttered, thinking of Dujing Pharmaceutical's drug research and development progress, two years is a little too ingenious.

After a while, Mo Yufei pushed the door and walked into the forensic department, and said with some excitement: "Team Lu, Ren Jianyun has arrived." ”

Lu Ke came back to his senses and smiled: "Okay, I'll go over now." ”

Lu Ke turned around and was just about to leave, but he stopped again and said to Jiang Xiran: "Just wait for the matter of going to the burial site, at least at dawn, the mountain road at night is still dangerous." I'll see if I can get some clues from Ren Jianyun's mouth for a while, and try to make you run less. ”

Jiang Xiran looked at him, and a smile appeared on his face: "Then I'll wait for the results of Captain Lu's interrogation." ”

In the interrogation room, everyone saw Ren Jianyun again.

But obviously, this time Ren Jianyun's state is the same as before. Even though he was still wearing a well-fitting suit, he was completely devoid of his original spirit.

Now he has the appearance of a down-and-out aristocracy.

In the face of the police's ironclad evidence, Ren Jianyun did not make any excuses, his expression was flat, and some were just endless emotions.

"From the moment I heard the news of Sun Jinyu's death, I knew I was finished.

Sun Jinyu is a madman, he won't let me go!

What's more, since he had a car accident, the whole person is abnormal, and he has become a complete madman!

Now I finally understand that all this is a script arranged by Sun Jinyu, why did he ask me to go to his home to talk about work, and why he suddenly became angry with me.

All this, from the moment I agreed to go to his house, this ending was already determined.

Why did he do it? Why do you have to put me to death?!

He doesn't understand anything, I'm doing something big! One piece can change the history of human science, and even divide the history of human medicine into two sections! All history has to be rewritten! ”

Ren Jianyun looked up to the sky and laughed, although he was a little hysterical, his mental state was quite stable, and the whole person was still relatively rational.

Subsequently, Ren Jianyun said everything -

Many years ago, Ren Jianyun was responsible for the research and development of drugs for the treatment of thrombosis, and the success of Sun Jinyu's marketing department, Ren Jianyun and Dujing Pharmaceutical Company have become the absolute core focus.

Soon, a second research project appeared, and Dujing Pharmaceutical Company was ready to develop a specific drug for dementia.

But this time the drug research and development process was not smooth, the company's capital chain was broken, the research fell into a bottleneck, and there was no one and no way to solve the current dilemma.

Because things have come to this point, the company can't even afford to buy experimental monkeys.

Drug research and development could not be suspended, and there was no sufficient experimental monkey and financial support, Ren Jianyun found Sun Jinyu.

After the two discussed, an idea of destroying humanity appeared.

It's not one way, but it's the only way.

That night, the two had a conversation in the office of a pharmaceutical company.

"Even if we had mice doing experiments and getting successful results. But when it comes to people, how much success rate will there be? ”

"I asked my sister-in-law, she studied medicine, and she said that there was only an 80 percent success rate."

"That means there's a 20 percent chance of failure......

The two looked at each other, neither of them said anything, but in their hearts, they both had some kind of expectation for one thing.

A few months later, Yikang Nursing Home was established, with Ren Jianyun as the director and contributing money.

Sun Jinyu has the experience and connections in the marketing department to find the right old people.

Their preferred target is the homeless who are demented, childless, nameless.

Because such a person suddenly disappears, no one will find out, and no one will look for it.

In this way, the Yikang nursing home became an invisible laboratory, a killing field that exterminated humanity and could not be forgiven.

The research and development of drugs is still continuing, but with more and more corpses in the mountains behind nursing homes, there is still no obvious progress in the research and development progress of drugs.

Ren Jianyun and Sun Jinyu both had a hard time riding tigers.

Sun Jinyu, in particular, had the idea of retreating.

Even if the drug is successfully developed in the end, more people can be saved, but what about the dead? Who will atone for sins?

Immediately afterwards, a car accident caused Sun Jinyu's new wife to die, but Sun Jinyu survived unscathed.

He thought it was his own retribution because he had sinned so much.

Since then, he has had serious mental problems, and then he found Ren Jianyun and wanted to quit the matter.

Ren Jianyun naturally would not agree, and Sun Jinyu wanted to expose his various crimes.

This incident is also the fundamental reason for the frequent quarrels between the two.

Ren Jianyun came to Sun Jinyu's house many times to discuss this matter with him, but Sun Jinyu was like crazy and had no way to communicate.

On the morning of Sun Jinyu's death, the two met again.

This time, Ren Jianyun didn't talk nonsense, and asked Sun Jinyu directly: "If the matter is exposed, which of us can live?" ”

Sun Jinyu smiled faintly: "Since I did that, I haven't wanted to live." ”
