With little hesitation, Johnson agreed to the offer to cooperate with the experiment.

Although the Huaguo researcher, Zhao Shuxuan, stressed to him that the relevant clinical trials had only been done twice on mice, and that direct application to humans could be risky, for Johnson, it was the only way for him to return to Earth.

If he can't get rid of the Martian germs on his body, he may have to stay on the Moon Palace for the rest of his life, be isolated from the Earth's ecosystem, or even be abandoned.

This is difficult for him to accept when he has a family on Earth and someone waiting for him to return.

Sitting next to the medical bed, quietly waiting for the two researchers in the infirmary to prepare the potions, after a short time, the Huaguo researcher who had brought him here earlier came over with three capsules and a small bag of water.

"Eat it."

Taking the three capsules from Zhao Shuxuan's hand, Johnson did not hesitate, threw them into his mouth, and then took a sharp sip of the straw containing the bagged water, and swallowed it with the water.

After sitting on the edge of the medical bed and waiting quietly for five minutes, Johnson looked left and right a little restlessly, and saw that everyone in the laboratory was looking at him, so he said something embarrassed.

"Uh, that's it?"

"I don't know," Zhao Shuxuan shook his head, "I won't know until I know the specifics, I suggest you lie down and sleep for a while." ”

Johnson: "May I ask, where did those capsules come from?" Don't get me wrong, I'm just curious......"

Professor Leslie and Professor Zhao Shuxuan glanced at each other, looking at him with a strange expression.

“…… Knowing too much isn't necessarily a good thing for you. ”

Johnson speculated: "Involving confidential? ”

"That's not it," Professor Leslie shrugged, "it's just...... Only one person has developed an immune response to the bacterium at the moment. ”

Without hearing the words in this sentence, Johnson frowned and asked, "So?" ”

Coughing lightly, Professor Leslie continued, "And this bacterium mainly resides in the esophagus, especially in the large intestine area......"

Johnson's face changed instantly.

Shet...... Could it be ......?"

"That's right, it's Shet...... Or Shet's extract, but I think there should be a lot of differences. ”

Feeling a churn in his stomach and resisting the urge to vomit, Johnson glared at him with murderous eyes and asked with difficulty, "Are you sure this thing is...... Does it work? ”

"I ...... Not sure," Professor Leslie smiled a little awkwardly, "but some things have to be tried, don't they?" ”

Johnson was about to say something, but at this moment, a feeling of sleepiness hit his brain, and he couldn't help but stretch out his index finger and press it on his eyebrows.

Sensing his condition, a hint of surprise flashed in the eyes of Professor Leslie and Professor Zhao Shuxuan.

With the last vestiges of consciousness, Johnson faintly heard the sound of the two men talking.

"God...... Our speculation was correct! ”

"The antibodies that can kill the X-0172 bacteria are indeed in the extract of the third colonist metabolite!"

“…… Report on the success of your research. ”

“……”

……

Almost at the same time that the researchers aboard the Moon Palace completed their experiments.

Jinling Institute for Advanced Study on Earth.

Lu Zhou, who had been paying close attention to the progress of the experiment, immediately came to the X-0172 Bacteria Special Laboratory established not long ago after learning the news of the success of the experiment, and asked Professor Liu Zuobing, the person in charge here, about the research on the Moon Palace.

"What is the condition of the two colonists now?"

"We slept very peacefully, we tried various physical methods such as low temperature, overheating, static electricity, etc., but they couldn't wake them up," Professor Liu continued, pushing his glasses, "Overall, the experiment was quite successful, and it was a confirmation of our conjecture." From metabolite sampling, traces of spores were observed in the metabolites of both colonists. ”

Lu Zhou's spirit perked up, and he immediately asked, "In other words, that Taiwei's body did produce antibodies to the X-0172 bacteria." ”

"Theoretically, it should be like this," Professor Liu nodded, but then sighed again, "but the trouble now is that even if we find an antibody that can remove some of the X-0172 bacteria from the colonists' bodies, it will be difficult to further kill the spores through antibodies." ”

Spores, also known as endospores, are bacterial dormant bodies, and are also known as the most tenacious living organisms in the biological world, with outstanding performance in heat, chemical and radiation resistance.

In the case of Clostridium botulinum, for example, it takes 5 to 9.5 hours for its spores to be killed in boiling water. Bacillus megamegali is 36 times more resistant to radiation than I cells, and can maintain its original life form for a long time even under direct irradiation of ultraviolet rays and high-energy rays.

Free-present spores have no obvious metabolic effect and only maintain latent germination forces, so they are also called hidden life. Once the environmental conditions are right, the spores are ready to germinate into vegetative cells.

To make an inappropriate analogy, it's like a dehydrated vegetarian bun of instant noodles thrown into boiling water.

Therefore, if the spores in the colonists' bodies cannot be completely destroyed, it will be a matter of time before the situation is good.

The atmosphere in the lab fell silent.

Staring at the paper from the Moon Palace on the computer screen, Professor Liu Zuobing fell into deep thought.

From the solemnity in the eyes of this old professor, Lu Zhou could clearly feel that it was not easy to solve this problem. Even if it integrates the world's top biomedical R&D capabilities, it is not easy to find a solution.

Lu Zhou: "About the spores...... Isn't there a good way to do it? ”

"If there is, we must have tried," Professor Liu shook his head, "International experts have met several times to discuss it, and at present, the more reliable idea is probably batch sterilization, which continuously activates the spores and then kills them." But this involves a bit of a problem, as we may be able to toss and turn a few times to reduce the amount of X-0172 bacteria in these colonists, but it will be difficult to get rid of them in the first place. ”

Lu Zhou: "It's like a cancer cell that has spread? ”

Prof. Liu: "It's not very appropriate, but it's not a big deal. ”

After listening to Professor Liu's statement, Lu Zhou thought for a while, and suddenly asked.

"What about those extracts that contain antibodies? Do we have one in our lab? ”

Professor Liu pointed to the sealed glass bottle on the table.

"Right here...... What's wrong? ”

Lu Zhou: "Can I bring one back for research?" ”

Professor Liu Zuobing glanced at Lu Zhou strangely, "Yes, yes...... Although I think it probably doesn't make much sense. ”

It's not that he doesn't believe in Lu Zhou's strength, but he doesn't think there's any point in doing so at all.

This is just a metabolic extract, and there are no X-0172 bacteria in it.

Even if you really want to study, you shouldn't study this thing, right?

Lu Zhou smiled faintly and said.

"Whether it makes sense or not, you will only know if you try it."
