Fang Qin, twenty-seven or eight, with a slender figure, the more Li Chengqian looks at it, the more he likes it.

Li Chengqian said: "I think that people are actually controlled by three places, the brain, the heart, and the bottom. ”

Fang Qin: "??? ”

She didn't know what Li Chengqian wanted to say.

"Many people think that they are controlled by the brain, but in fact it is not the case, let's talk about the heart, in fact, the heart also has memory, and the person who transplanted the heart will cry suddenly, which is the biggest proof that the heart has memory." Li Chengqian said.

Fang Qin was surprised, her heart could be replaced, she had never thought of such a thing.

"And the following is even more powerful, any creature, if you want to exist in the world for a long time, reproduction is indispensable, and we are different from other animals, we have too many distractions, which will make reproduction a very serious problem." Li Chengqian said.

Fang Qin didn't know what to say, so she had to listen carefully.

"As a result, in order to continue to reproduce, human beings have evolved a completely different system, a long estrus period, and the benefits of reproductive activities." Li Chengqian said.

"What's in it for you? For example, the impact on people's thinking, I have to mention that the biggest benefit of that kind of thing to people is that it can keep people's minds clear. Li Chengqian said.

Fang Qin finally understood what Li Chengqian was saying, and she blushed a little.

……

After a short time, Li Chengqian returned to the middle of the courtyard in high spirits.

"Well, now that my mind is clear, even if it is the most difficult problem in the world, I can solve it, and we can continue to discuss the cause of death of the deceased!" Li Chengqian said.

Everyone was surprised, why did Li Chengqian work hard for such a while, and after he came out, he was like a different person, so interested?

"Fang Qin, I want to ask you, did your husband eat anything else besides eating these stinky tofu before?" Li Chengqian asked.

"I don't know about that." Fang Qin blushed slightly.

"Does he have any bad habits?" Li Chengqian asked.

Fang Qin said: "He likes to draw water directly from this well, and he used to like to drink it, but he has never had an accident. ”

"There must be a problem with the well water! Hit it out and see. Li Chengqian said.

After the well water was pumped out, Li Chengqian picked it up and put it in front of his nose to sniff, and sure enough, he could smell a very subtle strange smell.

"I smell a little weird, you smell it, do you feel the same way as me." Li Chengqian said.

So, several people around came up and put their noses to the bowl one by one to smell it, and sure enough, although the smell was not heavy, it did exist.

Du He sniffed: "Why can't I smell it?" ”

Everyone looks at Du He like a fool, this kind of thing, don't say it if you can't smell it, everyone smells it, won't it be embarrassing to say it?

Li Chengqian didn't pay attention to Du He, he frowned, the problem of drinking water is very important, and groundwater is an important drinking water resource in ancient times, and it can even be said that it is the only way to obtain drinking water in many places.

The contamination of groundwater is not such a trivial matter as the death of a family, and it is likely to cause a widespread plague.

"Duhe, you go find someone, the wells near here need to be temporarily blocked, find out the cause of the well water pollution, and quickly eliminate the source of pollution, otherwise, the consequences will be unimaginable, and many people may die." Li Chengqian said.

Du He knew the severity and went to find someone, Li Chengqian asked, "Do you have any pen and paper?" ”

Fang Qin found a pen and paper, and Li Chengqian began to draw, he drew a warning icon of biochemical hazards, with three horns in a circle.

After the painting was finished, everyone around me was terrified, and this thing was really a little scary.

"You take this biohazard warning icon according to my drawing, and after you draw it, stick it on the side of the well in the nearby workshop, and tell everyone not to drink the well water." Li Chengqian said.

His entourage was busy, while Li Chengqian went out with Qi Zuo and Fang Qin to look for possible sources of pollution.

"Zhao Zilong, where do you think the source of pollution will be?" Li Chengqian asked.

"I don't know, but since it's related to water, let's go to a nearby well and have a look." Zhao Zilong said.

Li Chengqian did not agree with Zhao Zilong's statement.

The source of pollution should not be at the well, because the protection of the well water is still sufficient, and the wellhead is not only a stone that is a little higher, but also there will be no garbage nearby.

There will not even be garbage on the streets, littering is to be beaten, 60 boards, adult men can't carry it.

"Let's go to the place where the sewage is treated, Fang Qin, do you know the place?" Li Chengqian said.

"Yes."

Not long after, Fang Qin took Li Chengqian and Zhao Zilong to a nearby seepage well, a stone slab was covered on it, Li Chengqian immediately frowned, such a sewage treatment method is simply murder!

"Move the stone out of the way, and I'll see what's going on inside." Li Chengqian said.

Zhao Zilong said: "His Royal Highness the Prince, forget it, I'm afraid this thing is not good." ”

"If you want to move away, move away, what's the nonsense?" Li Chengqian was a little angry.

Zhao Zilong had to try, and he found that with his strength, he couldn't move away at all.

Fang Qin hurriedly stepped forward to help, but the two of them moved the stone, and they were still far from moving away.

"Get out of the way, I'll do it."

Li Chengqian stepped forward, grabbed the corner of the big slate, and forcibly pulled the slate apart, and suddenly, a pungent stench rushed up.

"Negative sentiment from Zhao Zilong, +148"

"Negative Sentiment from Fang Qin, +125"

Zhao Zilong rolled his eyes, his heart was really stinky, he obviously told Li Chengqian, don't open it, Li Chengqian has to open it, it's okay now, the stink is sky-high, and it costs people's lives!

"His Royal Highness the Prince, please close it after reading it, it stinks!" Zhao Zilong said.

"Fang Qin, I think your husband was killed by the water here, the water here seeped into the underground water system and polluted the groundwater, and your husband likes to drink raw water, so he was poisoned by the little insects in the book." Li Chengqian said.

When Fang Qin heard this, two lines of tears flowed down, she was very sad, how should this be? Isn't this dead in vain?

"This is the responsibility of our government, we are willing to compensate you for your losses, and our government is also willing to bear the cost of your children's future schooling." Li Chengqian said.

"Thank you, Your Highness the Prince." Fang Qin lay on Li Chengqian's shoulder and cried bitterly.

Zhao Zilong said: "Your Highness's decision is still very good, I admire it." ”

Who said that Li Chengqian is one of the three fools, isn't that good? Zhao Zilong thought in his heart.

"Okay, this matter can be solved, but this matter of seepage into the well is the most important thing to solve, otherwise, in the future, the incident of accidentally eating well water and killing people will always happen, so that Chang'an City will be chaotic, I have to think of a way." Li Chengqian said.

Zhao Zilong felt that Li Chengqian was too naïve, this seepage well was also a helpless move, there must be a place to put sewage, and it couldn't be transported by car, and he couldn't afford to pay for it.
