I receive courier in Datang

Chapter 235 Processing Plant

It was only when the ring was in Li Chengqian's hands that Li Chengqian had a comprehensive understanding of this ring. The workmanship of this ring is really simple. Apart from the special material, there is no merit in other places.

He remembered that the pre-Qin items he had seen in some pictures before were all exquisitely crafted, and he thought that these items had a long history.

It turns out that people at that time actually liked such simple things.

Li Chengqian said: "Have you seen, what is simplicity and what is great wisdom and foolishness! This is great wisdom and foolishness, you all should learn from it!"

Xiao Cui rolled her eyes, she began to bury this thing in her heart, isn't it just a simple ring?Not half as beautiful as Li Chengqian and Mo Yu’s wedding rings, they’re too ordinary!

This black ring looks like it was burned in a fire. That's why it's so black that it probably can't be washed off.

Du He was not interested in the ring, he thought about what to do with this big basket of fish.

This kind of fish should be delicious when boiled in fish soup, and it is also delicious when fried, or even grilled directly.

The more Du He thought about it, the more greedy he became, and he almost couldn't hold back his saliva!

Du He said: "Your ring is meaningless, put it away first, let's make this fish, it should be delicious."

"You just want to eat it. This thing is indeed a good thing. Let's try something new today!" Li Chengqian said.

In a dark house in Chang'an, an old woman in black robe suddenly opened her eyes.

"Our holy object has appeared, go find it, it's in Chang'an City!"

"Yes."

Several figures disappeared into the darkness.

"It's almost 1000 years! The legend is actually true! This time, we must invite it back and pass it on!"

Prince's Mansion.

Du He found a very interesting thing, that is the swim bladder in the belly of these small fish, it looks like two transparent balloons connected together.

He collected these things and arranged them in a row, and threw away all the other offal.

Li Chengqian was discussing things with Wangcai, so he didn't pay attention to the situation here.

"It stands to reason that you should eat the fish directly, regardless of the contents of their internal organs, but now that you know more, will you still eat the internal organs of fish?" Li Chengqian asked.

In fact, Wangcai has no requirements for this matter. It can be eaten or not. Anyway, it will do nothing if it eats it.

But since Li Chengqian asked it like this, it can't act like it has no pursuits, and can even eat the internal organs of fish.

Wangcai shook his head as a matter of course, it said it does not eat fish offal.

"This is even more strange. I remember that you like to eat fish because your body lacks a substance in the fish body. As far as I know, this substance should be high in viscera." Li Chengqian said.

He couldn't remember what was inside for a while, so he could only say that it was some kind of substance.

Wangcai is either nodding or shaking his head now. He is most afraid of Li Chengqian mentioning these things, and he doesn't understand them. If Li Chengqian only knows a little about them, it will be very troublesome.

However, Li Chengqian still helped Wangcai clean up the fish with his own hands, and Wangcai put the fish on the roof to dry and dried them so that they could be eaten later.

By the way, let the kitten take care of it on top, so as not to be eaten by other things.

Seeing Wangcai going back and forth like this, only one fish can be brought up at a time, Li Chengqian thought it was funny, of course he wouldn't help Wangcai, after all, it was quite fun.

Glancing at Li Chengqian elsewhere, he suddenly saw Du He with his swim bladders lined up, and immediately rolled his eyes, what's going on with this guy?What do swim bladders line up for?
Swim bladder is actually what fish use to control their own ups and downs, and it also has the function of assisting breathing. However, it is not as satisfying to eat as meat.

But Du He obviously didn't want to eat these fish maws. He put them on the ground and they were dirty. So, Du He just wanted to play with these fish maws.

???

What's so interesting about this thing?Li Chengqian said he understood Du He's behavior very well.

Soon, Li Chengqian took care of all Wangcai's fish, and he came to Du He's side.

"Du He, why are you arranging these things in a row?" Li Chengqian asked.

"Of course it will be the last one to pop these fish bubbles one by one. This will definitely be very interesting." Du He said.

"Fish... urine foam?" Li Chengqian was shocked.

He asked: "Du He, since you think this thing is a fish's urine bubble, then let me ask you, why is there no urine in these urine bubbles? Are they all empty?"

Du He stroked his chin, thought for a while, and said, "These fish must have urinated in fright when they were caught by us, and all the urine in their stomachs was expelled."

Li Chengqian: "..."

He was convinced by Du He, and this kind of ghost theory could be made up, and it sounded quite reasonable.

Li Chengqian sighed.

"Xiao Ningzi, explain to him what this is." Li Chengqian said.

Xiao Ningzi was a little puzzled: "Maybe it's just like what Du He said, this thing is indeed scared to pee."

Li Chengqian was speechless, these guys are really ignorant!Haha, the feeling of knowing these things without telling others is really enjoyable!

He didn't want to tell these people what it was, it didn't matter, he didn't need to know, and he didn't need to take a test.

The swim bladder was almost full, so Du He picked up two and gave one to Li Chengqian for him to play with, and kept one for himself.

Li Chengqian curled his lips: "Childish, I will never play!"

Du He didn't think so, he crushed the fish bladder in his hand and exploded it.

"Bah..."

It's fun!This thing is actually so loud, haha, I, Du He, am indeed a genius, even if it is a fish bubble, I can find a way to play it.

Seeing Du He playing like this, Li Chengqian inexplicably recalled the cannonballs he used to play when he was a child, small paper balls filled with potassium chlorate sand, which would explode when thrown on the ground or squeezed with hands.

Thinking of this thing, he was inexplicably a little emotional, yes, when I was a child, setting off firecrackers during the Chinese New Year was really a lot of fun!
He smiled and squeezed a fish maw.

"Bah..."

Quite fun.

Li Chengqian stood up and stepped on it. Immediately, more than a dozen swim bladders were crushed by him at the same time.

"Bah ah ah..."

The sound is endless. This kind of sound makes Li Chengqian feel as if he has returned to his childhood. It's so comfortable!

Du He: "???"

Why did Li Chengqian, who didn't pay much attention to his gameplay before, suddenly become addicted to it?Moreover, he crushed all the fish urine bubbles he had stored for a long time with one kick?
It's so cool to think about it!Du He couldn't help regretting in his heart, why didn't he act preemptively and trample all these things to pieces?

"You pay me! I just squeezed one by one, but you are good enough to trample all my toys!" Du He said.

Li Chengqian: "..."

"How about this, how about I ask someone to make some cannon throwing for us?" Li Chengqian said.

"What is a cannon throw?" Du He asked.

"It's a cannon that explodes when dropped on the ground." Li Chengqian said.

Duho was intrigued.

Then, Li Chengqian thought about the difficulty of this matter, how to make potassium chlorate?It looks so troublesome!
"It would be great if we could just use gunpowder and sand to throw cannons..."

Li Chengqian knew this was impossible because he had tried it and gunpowder sand would not explode.

"It seems that we can only use metaphysics. Make a wish today and receive the express delivery tomorrow!"

The cannonball is not very expensive, he can receive it.

"Tomorrow we will play cannonballs, and today we will eat fish." Li Chengqian said.

The matter of eating fish is not a big deal, and Li Chengqian said a lot of things about collagen, which made Mo Yuluo Li confused.

The Ministry of Industry sent someone to ask Li Chengqian to guide their sewage treatment ponds. Li Chengqian's eyes became focused. This is the most important thing.

Sewage treatment plant sounds like a very prestigious name, but when Li Chengqian arrived there, he realized that the place was really not that good.

Several newly dug large pools and several houses are not very decent.

"This is the sewage treatment plant you built for me?" Li Chengqian said.

"Your Highness, we found that this sewage treatment plant can't treat feces, it can only treat ordinary rainwater and vegetable washing water." The chief said.

"So backward..." Li Chengqian fell into deep thought.

He is very dissatisfied with such a sewage treatment system, but there is no way but to make a compromise.

It seems that he can only delay the pollution of groundwater, but cannot completely solve it. Therefore, tap water is the only solution to this matter.

When he thought of the money needed for such a big project, he felt a headache.

"Tell me what your sewage treatment plant uses." Li Chengqian said.

"The first row is a sedimentation tank, which mainly settles heavy things and buries them. The second row is a pool filtered with charcoal, and the effect is not bad." The chief said.

This was the idea that Li Chengqian had mentioned before, and the master had nothing to say about it.

This is the limit of what he can do. As for what is in the filtered water, at least it is invisible to the naked eye.

"Actually, gold can be extracted from the sedimentation tank," Li Chengqian said.

The principal's eyes lit up and he was very interested.

"How to operate?"

"I do not know."

Very good, isn't this just an empty rejoicing?

In fact, there is gold in the soil, and there is gold in the human body, but it is not cost-effective to extract it.

Li Chengqian said: "Yes, at least the most basic facilities are available. As for the upgrade, we will talk about it later. I am very satisfied with what you did this time."

As long as Li Chengqian is satisfied, everyone is very happy, hard work was not in vain.

"The factories here should be better built as much as possible, otherwise the workers here will feel very uncomfortable." Li Chengqian said.

"clear."

Li Chengqian thought for a while and said, "Take me to the sewage outlet."

"Yes."

Not long after, several people brought Li Chengqian to the sewage outlet. It was just a huge hollow cement pipe, and naturally there was no sewage.

The sewer was not open. Li Chengqian looked at the river with a strange expression on his face. He didn't think the ancient sewage was so powerful, at least there wouldn't be many strange things.

However, sewage has a huge impact on the nitrogen, phosphorus and potassium content of river water, which may cause a biological crisis.

"You need to find some people to monitor the water quality in the downstream all the time. If something happens, call me immediately, you know?"

"Your Highness, could you please tell me specifically what will happen so that we can have a reference?"

"There are suddenly more aquatic plants downstream, and the water even turns green. You should be careful about this kind of thing," Li Chengqian said.

"understood."

"Very good, come with me for a walk upstream." Li Chengqian said.

"I don't know what your Highness is doing upstream? There is no project for us upstream." The chief said.

"If it doesn't exist now, it doesn't mean it won't exist in the future. Let's go and find a place with good water quality and protect it. Maybe I will start a big project soon." Li Chengqian said.

"Please also express your Highness."

"Tap water project." Li Chengqian said.

Concise and concise, it's just these five words, but the people who followed him fell into endless imagination, did they come by themselves?Good stuff!

Everyone followed Li Chengqian and walked upstream along the river. On the way, they encountered many bridges, all of which were a few logs on the river, which looked very unstable.

However, this cannot stop everyone's enthusiasm for bridge repairs. There is a small bridge not far away.

Seeing that Li Chengqian was very interested in these bridges, the principal began to introduce them.

"Your Highness, this kind of bridge is very good. Every year when there is a flood, there will be no such bridge left, and all of them will be swept away by the water. However, as long as the water level drops, we can quickly build a new bridge." said the principal.

"Don't you find it troublesome?" Li Chengqian asked.

"It's much better than wading through the river, where the stones are covered with moss and it's easy to slip."

Li Chengqian nodded, noncommittal.

Chinese people like to build bridges, which is world-renowned. Sure enough, this strange hobby has been started since the ancestors.

Perhaps, it is to prove that human beings can transform nature.

I came across several good locations, but unfortunately they were all on the other side of the river. It would be unwise to let the water pipes pass through the river, as they might be washed away by heavy floods.

What's more, the weather has been good every year in these years, and the river swells greatly in summer. He doesn't think that the current technology can do this.

After encountering many bridges and cowherd boys, finally, Li Chengqian found a place that he thought was suitable, where the water surface was calm and suitable for renovation.

"Remember this, protect it first, put up a sign, it's called the water source protection area, I should use it here soon."

"Yes."

In fact, people don't quite understand what Li Chengqian means. This water is always flowing. To protect it, you have to protect the whole river.

Is it really useful to protect only this section?
What they don't know is that such protection is indeed useful, because the river has a strong self-purification ability, and a protected section of the river can make the water quality much better.

"Where can I find such a long pipe? It has to be an iron pipe. The craftsmanship itself is a problem. How can I mass-produce it?"

Li Chengqian began to have a headache.
