Not far behind Dr. Asasa, the guide, Mitsuhiko, Motota, and Ayumi, Chiba and Ashbara walked side by side.

"Future?" Gray Yuan was slightly stunned. "You're talking about...... My future and yours? ”

"Hmm," Chiba nodded. "It's important."

"Is something wrong?" Gray Plains wondered. "Is there the organization?"

"Yes," Qian Yu nodded helplessly. "It's about APTX-4869......"

"What's wrong?" Gray Plains frowned.

"After a lot of experiments, a team of professional researchers hired by Belmode found a group of white rats who, like us, were not poisoned at all, but were regressed to a juvenile state."

"Wait a minute, a group?" Gray Yuan asked again. "What does that mean?"

"Literally," Qian Yu said lightly. "They found several genealogies of white rats that would not have been poisoned directly. All individual mice with the characteristic genetic sequences of these families survived. ”

"And then?" Gray Plains asked. "What were the results of the follow-up trial?"

"The conclusion is, your antidote is a waste product." After Qian Yu finished speaking, he then looked at Gray Yuan Ai, and was not surprised to see an interesting expression.

It seems to be ...... The expression of a tigress cub whose territory has been violated?

"What do you mean by that?" Gray Plains asked. "You just said that the antidote I developed is a waste product?"

"I didn't say that," Qian Yu said. "But that's exactly what the report came from the organization, and as for the details...... It seems that the antidote can indeed help some mice to return to their original shape, but it seems that the mice also have permanent damage to their bodies. ”

"What do you mean?" Gray Plains continued to ask. "In what aspect?"

"In the first experimental group, 29% of the experimental rats died on the spot after being injected with the antidote; 33% of the mice recovered successfully but died within an hour; Thirty-five percent of the mice recovered successfully but died within three days, and only 3 percent, or four of the rats, survived for 15 days, but their telomeres were severely worn out, and their physical activity in a healthy state was still far from what it was before the first time it became smaller. ”

"This ......" Gray Plains' appearance of asking for guilt instantly softened. How can this be......"

"Didn't you do any follow-up experiments?" Qian Yu saw the strange state of Gray Plains' mourning.

"I didn't conduct follow-up universal experiments at that time...... "Gray Yuan's face showed a little helplessness. Since the research indicators given to me at that time did not include the development of antidotes, I just recorded individual smaller individuals and made antidotes for them...... But the antidote has a good effect on those individuals...... Although I didn't test my physical abilities, I also didn't have any cases of recovery failure or rapid death after recovery. ”

"You'll have to ask Belmode about the experimental team," Qian Yu shook his head. "I'm not an experimenter, you have to look for them for specific data."

"Can you help me contact them?" Gray Plains asked. "I'd like to see the specific data."

"How specific? When it comes to individual samples, I don't think I'll be able to complete the transfer either. But if it's just the core statistics for each experiment, I can give it to you quickly. ”

…………

In the stairs of a shopping mall, Chiba and Gray Yuan Ai walked up side by side. Just now, the two of them greeted the guide and Dr. Asasa and left the group under the pretext of shopping for their own goods.

"This ......," Gray Plains looked at the handwritten experiment report of Chiba. What they mean ......"

"yes," Chiba nodded. "It's not that it can't be developed, but it will take time."

"yes," Gray Yuan nodded. "It turns out that it does — but I think it's going to be a lot of work, isn't it?"

"So it will take time." Qian Yu sighed. "Really, I think maybe by the time the antidote was developed, we would have grown up enough to have a 17-year-old body without an antidote."

In their hands were research materials from Belmode.

After the end of the first set of experiments, they conducted a second set of experiments - providing the mice with extremely high concentrations of nutrients and injecting drugs according to the original statin cleavage protocol proposed by Sherry (statin is a common physiological inhibitory factor that inhibits cell division in the human body), starting from the nutrition of existing cells and stimulating cell division, so that the number of cells originally caused by the impact of APTX-4869 on the cell structure was reduced. The body that causes death as the individual becomes smaller is able to regain its original appearance through this scheme.

The results were rather subtle - most of the family mice did not survive 3 days, but one family of mice recovered almost all of them and had no major problems with their physical functions. (Actually, this is the same family of mice that Sherry used to test for the antidote and found that the antidote would allow the mice to recover completely.) ）

In other words, only a subset of families with a certain genetic trait were able to survive the devastating blow of APTX-4869, and only those families with another, rarer trait were able to successfully recover through the means now employed.

Now, Belmode's experimental group has succeeded in stripping out the DNA family of a mouse family with the resistance gene to APTX-4869. As long as the gene fragments that these mice have in common are analyzed and tested one by one, it may be possible to analyze which gene fragments make these mice more susceptible to human destruction than other mice.

But the problem is that, given the number of genes, it will take a long time to determine which genes give them such abilities. (It is even possible that the parts of the gene are not together at all, and then the amount of analysis will increase exponentially.)

Technically, this is something that can be done with the current level of technology, but in terms of workload, such a task will take a very long time to deal with even if it is handed over to the world's top scientific research team.

That's why Qian Yu said that they might not be able to wait until they were 17 years old to get a genome that could inhibit APTX-4869 and be short enough to be injected into their bodies and take effect by the current means.

With that, Qian Yu came to the door that led to the top floor of the rooftop and turned the doorknob. “？”

Qianyu's face suddenly became very strange.

"What's wrong?" Gray Yuan Wai noticed the strangeness of Qian Yu and asked.

"This ......" Qian Yu frowned, feeling the friction in his hand. Wrong...... This doorknob is so heavy! ”

Just as Qian Yu rotated the doorknob to a certain angle, the entire door suddenly opened quickly to the outside. Qianyu also reacted in time with the assistance of the auxiliary unit, and was not dragged forward by the door.

As the rooftop door suddenly opened, Chiba and Gray Yuan found a piece of cloth wrapped around the railing in front of them, swaying slightly in the wind.
