The sky was completely clear. Li Longji and the others finished their meal and took the clay carton and the blueprints with them.
Yao Chong found an excuse and ran away with them.
One hundred jars of fermented bean curd, twenty yuan per jar.
Yao Chong was given five jars on the way. He held one jar in his hand and shook his head, "Profiteer, you can obviously make bigger jars to hold more, but you insist on using small jars."
Li Chengqi couldn't stand others speaking ill of Li Yi.
He emphasized, "One jar for a thousand yuan. You have to open the lid and take it out. It will mess up the red side of the jar and spoil the red side of the jar."
Li Chengqi said red side, but Li Yi didn't call it fermented bean curd. He was afraid that others would guess the raw material from the name.
"One jar for a hundred yuan is fine! One yuan for two wen. "Yao Chong was still angry.
He found that he liked the taste and texture of fermented bean curd very much and wanted to buy more. However, he couldn't afford to buy 100 yuan per jar.
Li Longji didn't pay attention to the two. His mind was immersed in the clay carton.
He held two blueprints in his hand, one for clay carton and the other for wood carton.
Li Yi said that it was easy to make wood carton in war, but it could be used to grind rice and wheat. It needed strong soldiers to operate it.
It was made on the spot and then quickly removed the carton.
The army couldn't directly carry shellless rice grains as it was not easy to store them.
If there were cavalry and livestock, they had to be fed.
It was a good time to remove the shells and feed them with bran and chaff.
At this moment, Li Longji wished that all the farmers in the Tang dynasty could use this set of farming tools in the blink of an eye.
"Li Yi, a proud son of Heaven." Li Longji sighed as he recalled all the things that had happened to him.
Yao Chong heard and opened his mouth to say something, but in the end, he pursed his lips and looked at the sky.
Li Chengqi chuckled. "Does Prime Minister Yao feel indignant?"
"Farming, education, no." Yao Chong said frankly.
"Then what is it?" Li Chengqi asked knowingly.
"You, King Song, are the eldest brother of His Majesty. How can you take the possessions of a junior for nothing?"
Yao Chong was infuriated. Don't you know what King Song has done previously?
"Cheng Qi doesn't dare to agree with Prime Minister Yao's words. How can it be taken for free? Have you seen anyone stirring up trouble in the village? "Li Chengqi raised his chin.
He continued, "Even you, Prime Minister Yao, know that soy sauce, Red Square, and Hundred Boiled Round Eggs are delicious and expensive. Do you think other people won't be tempted?"
Li Chengqi made it clear that he was the one who used all kinds of connections to protect Li Yi's Zhuangzi.
"I can do that too," Yao Chong argued.
"Tsk!" Li Chengqi turned his head away in disdain.
Li Longji didn't want to listen to these two people bickering, so he said, "When we go back, I hope you can order the Agriculture Bureau to deal with the Tu Wu."
"I understand." Yao Chong's expression was solemn.
Young Dongzhu had given away the good stuff for free. If it wasn't promoted well, someone would lose their head.
***
At this moment, Li Yi's people on Zhuangzi's mountain started to get busy while the weather was fine.
In the paddy field, a group of people pushed the paddy horses to transport the rice seedlings. Li Yi asked someone to make oil clothes, but no one wore them.
They didn't ride on the paddy horses to transplant rice seedlings either. They thought it was too slow.
Wearing only boxers, they quickly bent over and planted rice seedlings in the paddy field.
The people on Zhuangzi's mountain moved the wheat that had been soaked in the rain to the Ba River and used the Tu Wu to quickly remove the husks.
They were going to eat this part of the wheat seedlings.
Li Yi ran back to his courtyard, closed three doors, and entered the cadaver storage room.
He took out the tools and practiced according to the contents of the book.
A few days passed like this.
23rd May.
The 42 students on Zhuangzi's mountain found other students to practice again.
Simple winding corridors, small bridges, and flowing water had been completed.
The water from the north flowed into the Imperial Plantation and then flowed down to Zhuangzi's mountain.
This water was used for the Winding Water Festival to be held today.
The water they ate on weekdays was from the five wells on Zhuangzi's mountain. They used tangerine to fetch water.
The tangerine was a lever. There was a weight behind it and a bucket connected by a rope in front.
When people were drawing water, they grabbed the rope and pulled down. When the bucket was filled with water, they let go and the bucket was pulled up.
By using the force of lifting water to push it down, it was easier for people to use force. There was also the participation of the body's weight.
Otherwise, they had to use a pulley and slowly shake it.
Or they could directly tie the bucket with a rope. There was a round hole at the bottom of the bucket and a piece of leather on the hole.
When the bucket entered the well, the bottom fell first. The water flushed the leather open and the water flowed into the bucket.
When it was lifted up, the leather closed and the water couldn't go out.
Of course, there were gaps. A small amount of water would still flow out.
It was like a one-way valve.
This function was also used on the tangerine. It wasn't a sealed wooden bucket that swayed on the water surface in the well to fill up with water.
The small change in Zhuangzi's method of drawing water from the well had been spread out. Others could understand it as soon as they saw it.
Li Yi waited for the people over there to arrive. He stood next to a well and pondered.
"Pressure wells need pipes and seals before water can be drawn up. In the past, the wells in the countryside used rubber seals and a one-way valve. What should I use instead of rubber?"
Li Yi recalled the wells used in the countryside. They were all sealed with the valve made by his family.
He cut the skin of the inner tube of the wheel and clamped it between two iron plates. An iron rod passed through and connected them.
"I wonder if bare leather will work?" Li Yi planned to use leather to seal it instead of rubber.
The water pipe was easy to make. He used cast iron pipes.
Thinking of this, he went back to the yard to draw. He didn't even need to buy the technology from the system. He knew how to do it.
When the drawing was done, he went out to look for the supervisor, Song De.
After asking around, he saw Song De at the construction site.
"Dongzhu, you came at the right time. The soy sauce and 100 boiled round eggs didn't sell well today. The price was too low. They didn't bid."
Song De was very angry. He took out the soy sauce. When one person in the group shouted a price, the others didn't say anything.
Li Yi laughed: "Colluding? Colluding. "
"Yes, Dongzhu. They are colluding." Song De agreed.
Then he looked at Li Yi expectantly. He knew that Dongzhu always had a good way to solve the problem.
"Sell it tomorrow. Tell them that there are only 100 catties of soy sauce. If the price is not high, sell it to them the day after tomorrow. Make the spiced tea eggs as well. Don't make so much tonight. "
Li Yi looked calm. If they want to share 200 catties of soy sauce, then 100 catties.
You businessmen and rich people continue to collude. Let's see who can't hold on.
"Is there any other way?" Song De took note of this and asked again.
"Secret bidding. Ask each of them to write down how much they are willing to pay and put it in a sealed box. Only tell them the highest price. The rest will be negotiated secretly. "
Li Yi gave another idea.
"What if they also discuss it in advance?" Song De didn't understand.
"If they discuss it in advance, they will give the highest price of 5,000 catties. When you shout, say that the highest price is 6,000 catties. Then we won't sell it."
Li Yi explained.
Song De instantly understood. When people colluded like this, they would suspect that the other party was willing to pay a high price. In an instant, the alliance would be broken.
He was in a good mood. Dongzhu was indeed Dongzhu. He was so powerful.
"Steward Song, find a craftsman to make it." Li Yi handed the blueprint of the pressure pumping well to Song De.
Song De flipped through two pages and frowned: "Dongzhu, is this an item to fetch water?"
"Yes." Li Yi nodded.
"Why is it so troublesome? We have a well. "Song De didn't understand.
"We are afraid that children will secretly fetch water and drop it into the well. Children can still play with this item."
Li Yi smiled. He imagined a child lying on the arm of the well, using his weight to pressure the water and jumping around.
Song De also smiled. His smile was warm.
