Put a lot of metal powder into the water, I am afraid it will really cause heavy metal pollution, when the fish are dead, the plants in the river will also be affected a lot, but there will really be an accident, how heavy the words heavy metal pollution is, people who have not experienced it will not easily understand.

Jian Zhen at least has a certain conceptual understanding of these words, if it really causes extremely serious pollution, it is quite difficult to control, and even they have to give up this piece of water source, and go to other places to get water from thousands of miles, when the water source is tight, even if Hu Tong fails in the end, they will suffer a lot of losses, and even this city will gradually become less prosperous, water conservancy is extremely important.

Jian Zhen told Dai Yixi his thoughts, although Dai Yixi didn't have much concept of the so-called heavy metal pollution, but he still decided to give it a try, found a large bucket of very clean water, and then put metal powder in it, and finally threw a fish into it, but soon after, the fish began to churn directly, and even showed a weak appearance, and it didn't take long for it to turn white directly.

Dai Yixi only paid attention to it this time, if the metal pollution is really serious to this extent, it will really be a troublesome thing, although metal is a very precious thing anywhere, but what Jian Zhen said is not necessarily any metal, so there is no need to use those precious metals.

"Even if it's just some ordinary metals, as long as they are metals, most of them can cause pollution, and there are very few metals that can help water quality."

That is to say, it is not necessary to use iron and copper, these more precious metals, it is also possible to use other metals, as long as it can cause pollution, in short, it is not impossible to cause heavy pollution in a short period of time, and even the possibility is that if Hu Tong really opens up and finds such a method, they are really very dangerous.

After Dai Yixi thought about it carefully, they began to think carefully, and after a long time, they spoke, although the current situation is indeed a bit troublesome, and it is impossible to have both fish and bear's paws, but now he is not sure whether Hu Tong has thought of such a solution.

After all, he didn't know that there was such a way before, which could pollute the water quality, if he got such a killing move before, of course, he wouldn't use it, but he might have seen it in some records, after all, there are a lot of various side records, and he has seen a lot, but he has never seen this statement.

"Since few people know about this method, then we have to think about it, well, it is possible that he does not know such a method at all, and then it will be unfounded, it is indeed impossible to have both, but I still want to try it, after all, this is a very rare opportunity."

Jian Zhen can also understand this mood, but he can't understand Dai Yixi's move to let the people take risks, so he still proposes to be more conservative, check it first, hold on to the army, and then make another plan.

If the other party really doesn't know such a method, and there is nothing that can cause heavy pollution to the water source in a short period of time, there is no way, then they can start directly without any worries, of course, the best situation is to prepare with both hands, Jian Zhen is ready to find some capable arts, to see if there is a certain talent for water source management, it is best to find Wang Wangwen.

Wang Wangwen doesn't know much about this aspect, but after all, he is also a doctor, and he has seen a lot of palace secret histories, and he still has a considerable say in medicine, and he is also quite familiar with some partial methods.

Wang Wangwen took a closer look at the experimental results that Dai Yixi and Jian Zhen had jointly sorted out, and finally frowned, and didn't say anything, not asking them where they knew about this method, but really began to study it seriously, how to clean up the polluted water quality.

Generally speaking, there are not many polluted water sources, anyway, after the passage of time, it is often possible, where the water source is clean or not, it is not a big problem, if it is really not good, the big deal is to move, after all, there is no major pollution, after all, this is ancient, how can there be so many chemical pollution.

Therefore, Wang Wangwen really does not have much experience in this area, and it is the first time to think about water quality.

"Your question is too tricky, I have to study it carefully, if it really doesn't work, then I can only try to contact my friends, you are not in a hurry in a short time, if you are not in a hurry, give me three or five months, you should be able to figure out some clues."

Jian Zhen was a little helpless, three or five months is really too long, for such a long time, Hu Tong has already started to do it, although there may be some clues about how to deal with it at that time, but if it is really done, the losses caused by this are immeasurable, and it is not even good to say that the materials they brought before, gold, silver and jewelry, etc., will be able to withstand the huge losses caused by this pollution.

No one can say how much damage pollution can cause, but if you really talk about it, it is definitely a super astronomical amount, and if it is not deep enough, it will definitely be a money-burning job to control pollution.

"Give me a while, I'll try to study and study again, you see what you want so urgently, I didn't have any preparation before, even if I want to contact my friends, how long will it take to fly pigeons back and forth, not to mention that I have to bring these experimental data to it, it is impossible for the pigeons to drive, so it will take at least a month to go back and forth." This is already the minimum.

Jian Zhen also knew that this was already the minimum, but some things could not be avoided.

"It's better to try your best, because I'm really anxious now, but you don't have to be too anxious, you can delay it a little longer, I'll try to discuss it with Dai Yixi." Jian Zhen said that it was a discussion, but in fact, he had already made up his mind, no matter what he said this time, he had to wait for Dai Yixi to come up with a mature plan, and then he would consider trapping Hu Tong.

Dai Yixi actually felt a little embarrassed here, but in the final analysis, it was for the sake of the overall situation, although Jian Zhen's proposal was a little tough, but he was not disgusted at all, after all, from the overall situation, he also knew that if he considered that it might cause water pollution, he should indeed be lurking.

At least there can't be many movements in a short period of time, even if you want to observe, you have to let people lurk, and fortunately they have trained this person before.
