Datang: The prince of salted fish was overheard by Li Er

"what!"

Li You did all his calculations, but he never thought that it was these four idiots who were sweeping goods and collecting books.

"What are these four idiots doing to buy so many books?"

Li You asked puzzledly.

"They, they didn't buy so many books to read."

Liu Yijie seemed to know the reason, but he was a little embarrassed to say it.

"I know, they bought so many books, of course they didn't read them themselves."

"It's just the four of them, who say they want to study, I don't know how many people's big teeth will be laughed out of."

"Just tell me what you have. If you don't say it now, don't I know?"

Liu Yijie took a deep breath and said, "Okay, I'll tell the prince."

"But the prince must make sure not to be impulsive."

After receiving a positive look from Li You, Liu Yijie said, "These four people put all the books in the toilet after buying them back..."

Liu Yijie didn't say anything later, but Li You already understood.

Dare to feel that these four people wiped their asses with their own books.

Li You was a little bit dumbfounded about this result that seemed to have no problem.

Because he himself is not much better than these four people.

He had done this when the paper workshop produced the first paper.

The only difference between Li You and the four of them is that Li You's paper has no words on it, so you don't have to worry about it being printed on your butt when you wipe it.

After traveling for so long, Li You felt that this was the most inconvenient thing.

People in this era don't have paper to go to the toilet. After solving their physical problems, they generally use "toilet chips" to deal with the aftermath.

It was a bamboo or wood chip three to five inches long.

These bamboo and wood chips were cut with a knife and polished smooth, so that the aftermath would not be so messy.

If it was just like this, Li You might not have so many troubles.

What bothers Li You even more is that these "toilet chips" are not disposable.

After use, it must be cleaned for next use.

Every time he thought of someone cleaning that thing, Li You felt a chill in his heart.

The picture was so beautiful that he couldn't even imagine it.

After Li You made paper before, both Chu Palace and Shence Mansion have realized the freedom to go to the toilet, but he has not promoted it to the outside world.

Firstly, there is a printing task, and secondly, it is also because the demand for this product is indeed huge, and it is really not enough to rely on only one paper mill.

Li You's original plan was to delay it a bit, but now that the usage has been developed by others, in order to prevent such degrading things from happening again, he can only move forward.

Li You smiled wryly and said: "This matter is easy to handle. From now on, the purchase of books will also be restricted. You can only buy five books of each kind at a time. Then sell the blank paper."

"Let these princes and generals buy white paper, so they don't have to worry about fading."

Thinking of the pictures of the buttocks of the Dukes and Generals, Li You felt another chill in his heart.

[I was thinking about something, what is there to see with the big white buttocks of a few men. 】

[No, those people must be very dark! 】

【Ah, ah, ah, get that picture out of my mind quickly. 】

If Li Shimin happened to pass by Li You at this time, overheard Li You's voice, and saw the picture in his mind, he would definitely not be able to sleep peacefully tonight.

Li You had just erased that image from his mind, when Xiao Er said that his uncle was entertaining guests downstairs and asked him to come over and show his face.

Li You already knew about Duan Lun's banquet downstairs today from Liu Ji.

Thinking that Duan Lun is not bad, and he still has one thing to discuss with Duan Lun, he got up and left.

Coming to the private room downstairs, the scene in the private room still made Li You sweat profusely.

This is not an uncle, he only came with these uncles.

Eldest Uncle Feng Shaoshi, Second Uncle Dou Dan, Third Uncle Chai Shao, Fourth Uncle Duan Lun and Fifth Uncle Yang Shidao.

Of course, Dou Dan is the most active among these people.

Seeing Li You coming in, Dou Dan immediately walked over and said, "Brothers, our cute little nephew is here!"

Li You also hurriedly saluted a few people, and they all returned the salute, only Chai Shao was still a little unhappy because of Li You's stealing from the Wannian County Prison.

Li You didn't care about it, and just kept congratulating Duan Lun on becoming Minister of the Ministry of Industry.

Duan Lun was so happy that he could not close his mouth from ear to ear and said, "This time we completed this work in less than 2 months. The three elders all think it is a miracle."

"Actually, if you want me to say, it's all thanks to His Majesty and the King of Chu."

"It is the method of taming cattle taught by His Majesty, the cement provided by the King of Chu, and the slaves acquired through trade. This time, the water conservancy in the customs can be sorted out so smoothly."

Then Duan Lun talked about what happened during the flood control process.

When they heard that water, sand, stones and cement could be turned into hard rocks after being stirred, all the people present were extremely shocked.

Especially Dou Dan, he was completely stupid.

Duan Lun spoke happily, and suddenly asked: "King Chu, now that the water control is over, will Shence Mansion continue to provide cement?"

Li You looked at Duan Lun strangely and said, "Why not? Shence Mansion set up a cement workshop to produce cement."

"After the cement is produced, it is for sale!"

"Why did Duke Ji ask such a question?"

Duan Lun blushed suddenly and said, "Actually, it's not that the Ministry of Industry wants to use it, but I want to buy some for myself."

It turned out that after Duan Lun was named Minister of the Ministry of Industry, his family renovated the old house of the Duan family in Wuwei.

Thinking of the excellent performance of cement in water control, Duan Lun came up with the idea of ​​using cement for reinforcement.

Li You chuckled and said, "Of course it's ok. I didn't sell it to outsiders before because the need for water control was much higher. Now that the water control has come to an end, the output of the workshop has also increased a lot."

"Naturally it will be sold externally."

"In the future, Ji Guogong needs to help me with the sales!"

Hearing that it was available for purchase, Duan Lun was overjoyed and asked, "I just don't know how to sell this cement?"

In the past, the Ministry of Industry used cement directly to the Shence Mansion, and the money was settled by the Ministry of Households. In fact, Duan Lun didn't know the price of the cement.

"It's easy to say, easy to say, how much uncle can use to repair the ancestral house, I will tell Liu Ji later, just go and pull as much as you want."

"Our family doesn't need to be so divided."

A lot of cement was transported away for water control this time. Even if the water control has been completed, there must still be leftovers from the Ministry of Industry.

As the minister of the Ministry of Industry, Duan Lun originally transported some cement directly from the warehouse of the Ministry of Industry to repair the house. It was not a big deal, but he still chose to buy it.

This made Li You feel more fond of him, and naturally became generous.

Duan Lun is not a hypocritical person, since Li You said he would give it away, he did not refuse.

"Then I would like to thank the King of Chu, but the King of Chu still wants to tell me a price."

"You should know that when the Ministry of Industry calculates the project, it also needs a cost."

"In the future, cement will be used more and more. If you don't know the price, the project budget will be troublesome."

Li You nodded and said, "The price of cement is 30 catties per bag, and the price of a bag is 200 Wen. If the Ministry of Industry makes a reservation one month in advance, the price can be discounted by [-]%."

After Li You finished speaking, the other people didn't think there was anything wrong, they just thought the price was not expensive.

But Duan Lun gasped.

The price of a bag is only 200 Wen, what is the difference between this and Bai Jian.
