The first legitimate son of the Tang Dynasty

Chapter 138 Flush Toilet and Bluestone (Third update please subscribe)

"You're stupid now. I told you a long time ago. Go back to your princess's mansion and show off to your Qinghe family. If you don't go, you have to come back with me. What do you think? Is your watch gone?"

In the corridor of Cheng Mansion, Cheng Chumo and Cheng Chuliang finished their dinner and were immediately driven back by Cheng Yaojin. When they went back, their faces were green and they chatted non-stop along the way.

"How did I know that dad would be so shameless? I thought it would be fine if he took it. After all, you are the eldest son. I am different. I am the second son. Hey, but who knows, he took mine to Auntie, what is this?
You can't be like this as a human being! "

Cheng Chumo looked at Cheng Chuliang and shook his head bitterly: "Hey, the most troublesome thing is asking us to recite the Four Books and Five Classics. Even if you give me a lifetime, I won't be able to recite that thing."

"Brother, can we go find Brother An again?" Cheng Chuliang looked at Cheng Chumo expectantly.

"How is that possible!" Cheng Chumo sighed: "His Royal Highness the King of Jin said that Brother An had a total of ten watches. Four of them were given to His Majesty, the Queen, the King of Jin and Princess Jinyang. The remaining six were given to you and me. Two pieces.

Now there are only four pieces left at An Geer's place. You have also seen the attitude at Leyouyuan today. None of those guys are eyeing the watch. We got two pieces, and we will go and ask for two more pieces, not to mention An Geer. Will we give it to you? Even if those guys find out, they will eat us alive. Alas, we brothers still don’t have that life.

Let's go back to sleep. There will be something good next time. Second son, hide yourself in the princess's mansion and don't go back to our Duke's mansion. "

Cheng Chumo sighed, and Cheng Chuliang was also speechless: "Brother, what is this? Why is our father like this? Whose father do you see robbing his own son? You really have nothing to say."

After saying that, Cheng Chumo and Cheng Chuliang separated bitterly and went back to their respective sleeping places.

Early the next morning, it didn't rain in Chang'an today. The sun came out again and the weather became hot again. Li An didn't want to sleep, so he got up early. Today Li An was going to start boiling salt.

Of course, such a simple thing as boiling salt does not require Li An to do it. Li An got up early, had a breakfast, and then prepared to make the first flush toilet in Datang. This first flush toilet was of course for himself. My daughter Li Duoduo did it.

You don’t know that in this dry toilet, if you squat in the winter, you will be freezing to the core, but if you squat in the summer, there will be many maggots crawling down there, and at night, the mosquitoes will make your white buttocks very wet. They are all small packages one by one.

Maybe you will say, don't let Li Duoduo squat in the dry toilet, and let someone serve that kind of wooden toilet at home, but Li An doesn't want his daughter to be taken care of like this. I hope Li Duoduo will do it by herself.

If you need someone to help you even go to the toilet, Li An doesn't want to raise such a playboy. Li An hopes that his daughter will know the sufferings of the people, and he doesn't want his daughter to become a person who knows nothing in the future.

However, Ang Lee doesn't want his daughter to suffer more, so the flush toilet is his father's love.

Of course, the most important thing is that you can make money, because making this toilet is not that difficult. There were pouring and molding techniques in ancient times. This technology is simply to polish a finished product by hand first, and the winding and twisting parts cannot be made. , can be cut into several parts, and then a negative mold is made based on the assembled sample, and the finished product is poured in batches based on the negative mold.

Due to the hollow S-shaped drainage pipe and curved spatial structure of modern toilets, a complete toilet requires multiple plaster molds from different parts to be combined into a complete female mold for pouring.

There was a well-developed ceramic manufacturing industry in ancient times. It should not be a big problem for ancient craftsmen to remanufacture finished products with molds.

Of course, the water tank shell can also be made of ceramics, but the automatic water discharge and replenishment structure inside must be clarified first.

Water outlet: This is simple. In fact, the switch and plug are connected with a rope. When not in use, the water pressure plug blocks the water outlet. When in use, pull out the plug and release the water.When the water tank is out of water, the plug falls back and is pressed firmly by the replenishing water.Water replenishment: The water replenishment port is equipped with a float valve. The float will rise and fall with the rise and fall of the water level in the water tank. When the water level drops, the valve opens downward to replenish water; when the water is full, the gate moves upward to block the water replenishment port to stop replenishing water.

The only troublesome thing is the sealing problem. The ancients did not have rubber, but Li An can bring a few sealing rings from modern times, and some screws, and fix them directly. There is also tap water. Li An can build a water tower so that the water for flushing the toilet can be used. Yes.

it's actually really easy.

Then someone will definitely ask whether these flush toilets can be produced in large quantities and sold so that the people of Tang Dynasty can enjoy them.

In fact, flush toilets still have to go the high-end route and are sold to those wealthy families. If you want to benefit all the people in Chang'an, it is impossible, because feces is an important fertilizer for people's fields. If you see your feces being washed away by water, , those people will go crazy.

Therefore, the sales targets of flush toilets can only be those from aristocratic families, and ordinary people will buy your flush toilets only if they are stupid.

Li An just walked downstairs with the drawing in his hand, and Liu Fangzi walked in with a happy expression. Li An looked at Liu Fangzi with a smiling face and asked, "Is there something good?"

"Returning to Mr. Lang, our lard was delivered to us by those from the slaughterhouse today, and they promised that it would be the same as before, and then they even lowered the price a little." Liu Fangzi smiled at the corner of his mouth.

Li An nodded and smiled: "It's the result of my eldest brother and second brother's efforts."

"That was Dalang and Erlang of the Cheng family. They came to the door together and cursed Wei Rentu. I heard that after he left, Wei Rentu vomited blood, and then he fell ill. Since then, the marriage of Wei Rentu and Wei Wangning has been postponed."

"Oh." Upon hearing Wei Wangning's name, Li An's eyes revealed a complicated look.

However, before this complicated look dissipated, Liu Xiatian walked in from outside: "Mr. Mr. Jin, Mr. Lang, is here. He also brought a lot of bluestones that you need, Mr. Lang."

"Lao Jin is here with the bluestone." Li An's face improved slightly, and he quickly said: "It's really great. With the bluestone, we can make soap.

Let's go, let's go out together to welcome Lao Jin. "

Li An took the lead and walked out of the house. Liu Xiatian and Liu Fangzi followed behind with smiles on their faces. At this time, Li An was very happy. Bluestone is actually limestone. The phrase "thousands of hammers and thousands of hammers carved out the deep mountains" in the lime chant refers to bluestone. .

This thing can be burned into the slaked lime Li An wants. Add slaked lime to the soap, and then add a little spice or flower solution, and the soap will appear. This soap is what Li An is preparing to cut off the leeks of the nobles.

So Li An was very happy at this time.
