On the tenth year of the natural disaster, I went to farm with me

Unpolluted spring water is a precious and scarce resource. It was one thing that we knew it tacitly before, but it is another thing now that Xia Qing has taken the initiative to tell me.

This was the greatest sincerity she could show in cooperating with him. Zhang San smiled, "You should know that there are several unpolluted springs in Huisan Base, right?"

Xia Qing replied, "Yes. There were originally four, but two of them were destroyed. Now there are only two left."

Zhang San nodded. "Huiyi Base will provide me with enough spring water for my research, so I don't need to take it from your territory now. You can just send me the hot spring water from Mount 50, which is safer. Excluding the two elements of Qiangyi, the water quality of Mount 50 is basically the same as that in your territory, and both are high-quality spring water."

The word "insurance" really touched Xia Qing's heart. She took advantage of her idol's good mood and humbly asked, "Third brother, what criteria do you use to evaluate the quality of spring water?"

Zhang San was in a good mood, so he patiently answered Xia Qing's common sense question. "Spring water gushes out from the mountain, so the chemicals in the spring water mostly come from rocks, minerals or various minerals in volcanic gases. Springs in different geographical regions contain different chemicals. The basis for judging the quality of spring water is whether the minerals contained in the spring water are harmful or beneficial to the human body."

Zhang San raised the test results in his hand and showed Xia Qing the element content. "These two springs are the best of the four major categories of springs - carbonate springs. They contain calcium carbonate, magnesium carbonate and sodium carbonate at the same time, and the pH value is weakly alkaline. They are the best carbonate springs and are known as the water of life."

Wow, wow!
Xia Qing's eyes lit up. No wonder Team Doctor Wang was so excited when she brought the spring water to Territory No. 1. It turned out that her pollution-free spring water was the best of the best.

King of Kings!
"If you are interested, you can look it up yourself about the importance of calcium, magnesium and sodium to the human body. In short, this spring water is very beneficial to the human cardiovascular system, nervous system and endocrine function, and has high medical and therapeutic value. When you took the medicinal bath, you used spring water, right?"

Xia Qing nodded immediately.

"Keep using it. You can soak more often when you're not taking the medicinal bath. This spring water can soften the skin's keratin, moisturize and whiten the skin. The quality of natural hot springs like the one at Mount Fifty was known as 'Beauty Soup' before the disaster."

Hearing the three effects mentioned by her idol, Xia Qing's first reaction was not to soak more, but to soak less. She wanted to moisturize the skin and whiten it, but, "Third brother, the stratum corneum of the skin is softened, isn't it easy to get hurt?"

Zhang San rolled his eyes at her and said, "Theoretically, yes. But do you think the medicine I prepared for you is just for fun?"

That's not possible, absolutely impossible!
Fan Xia Qing immediately expressed her opinion, "After using it for two months, I felt like my bones and joints were coated with a thick layer of lubricant, and I felt comfortable everywhere. Although I have never used other people's medicines, I believe yours is the best, because you are a scientific research leader standing at the top of the pyramid of Blue Star!"

"The top of the pyramid is too narrow. I can't squeeze in with my current ability."

Zhang San showed a satisfied expression, and after a modest remark, he reminded Xia Qing, "Now is the year of natural disasters, and the living environment is harsh. It is indeed very beneficial to keep a certain thickness of stratum corneum on the palms and soles of the feet."

"I see. Thank you, Third Brother." Xia Qing told the question that concerned him the most on this trip. "Third Brother, do you think that the hot spring at No. 50 Mountain was also a pollution-free source in the past?"

Zhang San stared at the test results with his eyes downcast. "It's possible, but not very likely. There are two adjacent mountains with unpolluted water sources. There is no precedent in China."

Xia Qing listed the reasons for his statement, "The people living in the valley moved into the bear cave near the crack in the winter of the second year after the natural disaster. Then, they dug a passage from the bear cave to the crack in the mountain, widened the valley, and filled it with soil to grow crops."

"The rocks there are very hard. The passage they dug from the bear cave into the valley is more than 8 meters long. The cave entrance is more than 300 meters away from the spring, and the valley is about 20 meters wide. According to the video on the mobile phone, although they have more than 20 people, there are only 8 strong laborers. In the process of opening up the valley, the coexistence of rainstorms and various dangers in the evolutionary forest caused a high proportion of casualties. Therefore, it will take them at least half a year to widen the area from the cave entrance to the hot spring." "During this half year, they must have diverted the spring water for domestic use. This should enhance their resistance and stimulate and promote evolution." Xia Qing handed the second to last video to the idol and continued.

"The population evolution rate in our country during the first two years of a natural disaster is 3‰, but the three people in the video, without protective clothing and medicine, survived until the third or even fourth year of the natural disaster. Third brother, does this mean that the three of them are evolvers?"

Zhang San pushed his glasses upwards and took it seriously. "The probability is very high, especially for this old man. The evolution rate of people over fifty is less than one in five hundred thousand, so this old evolver is a low-probability phenomenon. There is a high possibility that he was blessed by the polluted spring water. Is this the last record?"

Xia Qing was very happy that her speculation was recognized by her idol. She turned to the next video and introduced it to her third brother, "The person who filmed the previous video is this person. She is the last person in the valley and survived the third rain in the seventh year of the natural disaster."

After watching the video, Zhang San asked Xia Qing seriously, "Besides you, who else has watched this video?"

Xia Qing's heart immediately hung in the air. "Except for you, I haven't shown it to anyone else, nor have I mentioned it."

Zhang San asked again, "Besides you, who else has entered that valley?"

Xia Qing replied, "Yang Jin, I asked him to go in and get the peanuts for me. He set up the disaster relief command room in the bear cave. I don't know whether he went in later or not. But he promised to keep it a secret for me, so no one else must have been in there except him."

Zhang San breathed a sigh of relief. "Have you heard about the underground experimental project of Huiyi Base Research Institute?"

Xia Qing nodded, "I've heard that Shi Jiayi is related to the underground experiment?"

Zhang San leaned back in his chair weakly. From his expression, it was clear that he was extremely reluctant to talk about these things. "Shi Jiayi's sister, Shi Jiaran, was one of the victims of the underground experiment project. She was a resilience evolver."

Xia Qing was surprised, "Like the Fire Phoenix?"

Zhang San nodded slowly. "Her evolution level is higher than that of the Fire Phoenix, so she was treated as a precious experimental subject and suffered much less than the Fire Phoenix. Not long after she was rescued, she disappeared."

Xia Qing felt heavy-hearted, "Who took her away?"

Zhang San rolled his eyes at Xia Qing and said, "I let her go secretly. Only three people know about this. Me, Shi Jiaran, and you."

Xia Qing immediately straightened his back and was about to promise not to reveal the secret, but was stopped by Zhang San.

"In recent years, various forces have been tracking down her whereabouts. Leave the phone with me. Go to the valley immediately and completely remove all traces left by Shi Jiaran's relatives in the valley that may reveal their identities. Notify me when you arrive at the Bear Cave, and I will call Yang Jin over. The fewer people who know about this, the better."

"Understood." Xia Qing stood up, opened the door and entered the long and narrow corridor, and found Yanlong standing in the corridor. (End of this chapter)
