The sky was completely clear, and Li Longji and the others had dinner and brought clay and drawings.

Yao Chong found an excuse and ran away with him.

One hundred jars of bean curd, one jar of twenty pieces.

Yao Chong was divided into five altars when he was on the road, he took one altar in his hand and shook his head: "Profiteer, obviously you can make a bigger altar and install more, but you have to use a small altar." ”

Li Chengqi couldn't see others say bad things about Li Yi.

In that he emphasized: "A thousand pieces of an altar must always be opened and taken, which will make the red side in the altar messy, and will make the red side in the altar broken." ”

Li Chengqi said that the red side, Li Yi is not called bean curd, for fear that others will guess the raw materials from the name.

"A jar of 100 yuan is fine! One piece and two texts. 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, but he couldn't afford to eat it for 100 yuan.

Li Longji didn't pay attention to the two, his mind was already immersed in the soil.

In his hand, he held two drawings, one for soil and one for wood.

Li Yi said that when marching and fighting, wood is easy to make, and it can grind dry rice and wheat, and it takes strong men to operate.

That's what makes an improvised and then quickly unshells.

The grain and grass in the army cannot be directly carried without shell rice and millet, and it is not easy to preserve.

If there are cavalry or livestock, give them food.

Just take off the shell with the shell, bran, and bran, and use it for feeding.

At this moment, Li Longji couldn't wait to blink an eye, and all the farmers in the entire Tang Dynasty used that set of farm tools.

"Li Yi, the pride of the sky." Li Longji thought back to one thing after another and sighed with emotion.

Yao Chong listened, opened his mouth, and wanted to say something, but finally pursed his lips and looked at the sky.

Li Chengqi laughed twice: "Yao Xiangke is not angry? ”

"Farming, education, no." Yao Chong was calm.

"So what's there?" Li Chengqi asked knowingly.

"Your King Song is the eldest brother of His Majesty, how can you take the things of your juniors for nothing?"

Yao Chong was angry, you are a Song King, what did you do before, you don't know?

Yao Xiang said this, Chengqi didn't dare to agree, how could he say it in vain? Can you see that someone has come to the village to cause trouble? Li Chengqi lifted his chin.

He also said: "You Yao Xiang all know that soy sauce, red square, and boiled round eggs are delicious and expensive, so don't worry about others?" ”

Li Chengqi made it clear that it was me, it was me who was using various relationships to protect Li Yi's Zhuangzi.

"It's okay to be the same." Yao Chong argued.

"Shh Li Chengqi turned his head disdainfully.

Li Longji didn't want to listen to the two people arguing, and said: "When I go back, I still hope that Yuanzhi will order Sinong Temple to operate the earth." ”

"The minister knows." Yao Chong's expression was serious.

The young proprietor of a good thing is given out for free, and if it is not promoted well, someone will have to lose his head.

***

At this time, the people on Li Yi Zhuangzi took advantage of the sunny weather and got busy.

In the paddy field, a group of people pushed rice seedlings and horses, and Li Yi asked someone to make oil clothes, but no one wore them.

They also don't ride on rice horses to plant seedlings, which is too slow.

Wearing only boxers, they quickly bent over and planted rice in the paddy fields.

The people of Zhangjia Zhuangzi moved the wheat that had been drenched in rain to the edge of Bashui and quickly peeled it with soil bulge.

This part is what they are going to take and eat at home.

Li Yi ran back to his courtyard, closed the three doors in a row, and entered the general teacher's storage room.

Take out the tools, compare the content of the book, and practice carefully.

If that is how many days have passed.

May 23.

The forty-two students on the Zhuangzi found the other students again and started the party.

Simple winding corridors, small bridges and flowing water have been made.

The northern branch of the Caoyun water system flows into Huangzhuang and then flows down into Zhuangzi.

This water is used for today's Qushui Liuzhen.

On weekdays, five wells were dug on the Zhuangzi and water was drawn from orange trees.

The orange tree is a lever with a weight behind it and a bucket connected by a rope in front.

When the person draws water, he grabs the rope and exerts force downward, carries the bucket with water, and lets go, and the bucket is pulled up.

The force of lifting water upwards is used to press downward, and it is easier for people to exert force, and the body's own weight is involved.

Otherwise, use a roller and shake it slowly.

Or you can tie the bucket directly with a rope, and there is a round hole at the bottom of the bucket, and there is a piece of skin on the hole.

When the bucket goes into the well, the bottom falls first, and the water flushes the skin and boils, and the water enters the bucket.

When it is lifted upward, the skin is closed, and the water cannot come out.

Of course, there are gaps, but there is still a small amount of water that will flow out.

Like a check valve.

This function is also used on orange trees, rather than a wooden barrel with a sealed bottom dangling on the surface of the well to fill the water.

The small change of Zhuangzi to draw water from the well has been spread, and others will see it when they see it.

Li Yi waited for the people over there to come almost again, and he stood next to a well and pondered.

"Pressure wells need pipes and seals before they can absorb water, in the past, the rural wells were sealed with rubber seals, plus a one-way plug valve, what do I use instead of rubber?"

Li Yi recalled that the Yangjing used in the countryside was made by his own family.

The leather of the inner tube of the cut wheel is sandwiched between two pieces of iron, and an iron rod is threaded through it, and it is connected.

"I don't know if bare board leather will work?" Li Yi plans to use leather to seal and replace rubber sheets.

Water pipes are easy to do, cast iron pipes.

Thinking about it, he went back to the yard to draw, and he didn't need to buy technology from the system, he would.

When the picture was ready, he came out to find the steward Song De.

Ask people, turn around, and see Song De at the construction site.

"The proprietor, you came just in time, today's soy sauce and boiled round eggs are not selling well, the price is low, they don't bid."

Song De was very angry, the soy sauce was taken out, and a group of people had a shout, and the others did not squeak.

Li Yi smiled: "Bid-rigging? Collusion is good. ”

"Yes, proprietor, they are united." Song De agreed.

Then he looked at Li Yi expectantly, he knew that the proprietor always had a good way to solve the problem.

"Sell it tomorrow and tell them that there is only one hundred catties of soy sauce, and if the price is not high, fifty catties the day after tomorrow. Do the same with spiced tea eggs, don't do so much tonight. ”

Li Yi's face was calm, if he wanted to divide two hundred catties of soy sauce, it would be one hundred catties.

Continue to unite with you merchants and rich and noble, and see who can not hold on.

"Is there any other way?" Song De wrote this down and asked again.

"Dark mark. Tell each of them to write down how much money they put out and put it in a closed box. Only the highest bid price is said, and the others are secretly handed over. ”

Li Yi gave another solution.

"And what if they also discuss it in advance?" Song De didn't understand.

"They discussed in advance, and gave up to 5,000 yuan and 10 catties, and when you shouted, they said that 6,000 yuan was the highest, and then we didn't sell it."

Li Yi explained.

Song De instantly understood, and the people who united in this way would suspect that others were paying a high price, and the alliance would be broken all of a sudden.

He was in a good mood, the proprietor was really the proprietor, and he was so powerful.

"Steward Song, you find a craftsman to make it." Li Yi gave Song De the drawing of the pressure pumping well in his hand.

Song De flipped through the two pages and frowned: "The proprietor, but what is the thing to take water?" ”

"Exactly." Li Yi nodded.

"Why is it all so troublesome? We have wells. Song De didn't understand.

"I'm afraid that children will take water privately and fall into the well, and children can still play with this thing."

Li Yi smiled, thinking about the child's whole body lying on Yangjing's arm, using his body weight to press the water, and jumping up and down.

Song De also smiled, with warmth in his smile.
