Next, Yan Qing searched through all the materials but could not find any further experimental records related to Xiao Boqian.

Then the data suddenly stopped here. The latest experimental record was on December 6, 2021, a full twenty years later.

The person who started recording again became the Dean Xu she knew—Xu Wenwu.

This person's writing style seems to have changed, but he also seems particularly familiar with the early theories of the Xiao brothers. His fervor regarding human gene evolution drugs is also far greater than that of the Xiao brothers.

Yan Qing also saw his experimental records, which mentioned at the beginning that Xiao Boqian suddenly stopped the human gene evolution experiment for some unknown reason and destroyed all the human gene evolution drugs.

Even the experimental data was destroyed in crucial places, which directly caused the difficulty of restarting the experiment to soar to the highest level.

However, Dean Xu was also very capable. He obtained a project investment of one billion yuan from Tianxia Group through some means! With this investment, he rebuilt a new laboratory on the basis of the original underground laboratory.

However, due to the lack of crucial experimental data, his existing technology was unable to extract JYJH1 from a small amount of blood sample. This problem had puzzled him for a long time.

It wasn't until Tianxia Group sent him a new assistant that Dean Xu, with the help of this assistant, came up with a daring idea to risk a large number of lives to extract JYJH1.

Yan Qing felt somewhat ashamed upon seeing this. Was this the legendary case of trying to compensate for insufficient quality with sheer quantity?

Thus, Dean Xu and Tianxia Group began a new type of swindling and deception, specifically targeting naive young students who came to Wenshan Sanatorium under the guise of internships.

Ostensibly providing practical work experience, they actually committed murder and cruel killings behind closed doors, all for the sake of extracting a tiny, insignificant amount of JYJH1 substance from the victims' blood.

Upon seeing this, Yan Qing instantly understood the whole story. The reason there were so many "patients" in this sanatorium was that they were all just "blood cows" being raised in captivity.

As for the remaining small number of "doctors, nurses," and "ordinary employees," they are likely just personnel providing cover or downstream services.

Yan Qing broke out in a cold sweat. She finally understood that she was the lucky one all along. And the reason she was so lucky was simply because she said "thank you" to the bus ticket seller.

It was because of this "thank you" that the ticket seller quietly told her that "the right side is lucky," which led her to get the job as a doctor and prevented her from being harmed from the start.

However, there was still something she couldn't understand: why were the reactions before and after taking the human gene evolution drug JYJH1 so drastic?

According to Xie Xiaoboqian, who conducted the original experiment, this JYJH1 was a great success. Although it couldn't immediately awaken spiritual power, it significantly improved both mental and physical strength. The reason why Wenshan Sanatorium became so famous was precisely because of it.

However, twenty years later, JYJH1 became something that all patients avoided like the plague. Not only did it offer no benefits, but it also had very obvious side effects, and many patients died painfully after taking this drug.

It doesn't seem like a good thing at all.

However, Yan Qing couldn't find any more records. It seemed that Dean Xu hadn't kept the core secrets in the archives. It seemed that there must be other explanations for this new so-called JYJH1.

Leaving the archives, Yan Qing passed by a man who was convulsing violently in pain. During his convulsions, the strange metallic wire became exceptionally bright, sending continuous streams of light towards the giant metal sphere in the air, and then extending into the white space capsule.

The next moment, the person who had been convulsing violently suddenly kicked out with all four limbs and fell silent instantly.

Yan Qing stepped forward and checked his breath. As expected, the man was already dead.

His body's skin began to turn an almost transparent pale white, and even the capillaries beneath the skin were clearly visible.

The manner of this death was almost identical to the "mountains of corpses" she had seen in the "safe house".

Yan Qing sighed and left silently.

The lab had reached its end; all that could be seen was a wall. Yan Qing decided to retrace her steps and check if Assistant Zhu had left.

Just as she turned around, Xiao Tao grabbed her clothes. "Big sister, come with me to a place. I feel something familiar there."

Something familiar? Yan Qing was a little confused, but she still followed Xiao Tao over.

Xiao Tao stretched out her small, white hand and began to feel her way along the laboratory wall. It took her five or six minutes before she stopped at a certain spot.

"Big sister, this is it. Can you help me open it?" Xiao Tao looked up at her expectantly.

Yan Qing looked at the white wall in front of her, which was exactly the same as the one from before, and began to feel troubled. There was clearly nothing here, wasn't there?

She knelt down and patted Xiaotao's head, saying gently, "Xiaotao, when you said 'open it,' did you mean this wall?"

Xiao Tao nodded. "There are some things I need behind here, big sister, please help me."

"But how can I open it?"

Xiao Tao then realized that her older sister was just an ordinary person and there were some things she couldn't see. So she thought for a moment, then stretched out a finger, brought it to her lips, and bit it hard.

In an instant, bright red blood flowed out.

Xiao Tao waved to her, "Big sister, lower your head."

Yan Qing slowly squatted down and saw Xiao Tao rub her blood-stained fingers on her eyelids a few times, then clap her hands and say,

"Okay, big sister, why don't you take another look and try again?"

Yan Qing's eyelids burned, as if they were stained not with Xiao Tao's blood, but with highly irritating sulfuric acid. The burning sensation felt like it was cooking her eyes, and it took quite a while for it to gradually subside.

Yan Qing opened her eyes and found that the original white wall had disappeared.

At first glance, what was originally hidden by the white wall turned out to be an old underground air-raid shelter passage.

Yan Qing stood at the entrance of the passage and observed that the air-raid shelter was probably built during the Anti-Japanese War. However, after the founding of the People's Republic of China, many of them were forcibly demolished by the government.

This is exactly what's happening right now. The passage was originally supposed to be much longer, but most of it has been covered up with cement. The part that's currently exposed is only about ten meters long.

But it was precisely within those few meters that Yan Qing hesitated for a long time before finally daring not to enter.
