"Finding an excuse to come out and play. Do you want to leave me behind? Hmph! How despicable, "Li Longji muttered.
Yesterday, the Winged Knights told him that Li Yi was going to build the Yellow River Bridge. He didn't think much of it. Just fix it!
Who would have thought that they would all go to Lantian County together in the morning?
You all leave, and I'll be bored in Zhuangzi? How dare you!
Go, all of you, it's not that far away.
If there was an emergency elsewhere, the Winged Knights would come to report. No one would want to attack Chang 'an, right?
If a group of enemies suddenly attacked Chang 'an, they would look for Brother Yi.
Liu Jieyu, Wu Jieyu, Empress Wang, and the others were happy and brought their children out to play.
In the past, traveling was a big deal and they were afraid of being assassinated.
Now, if someone wanted to assassinate them, it was hard to say if they could damage the car.
Let's not talk about swords and bows. Let's see how many times you can smash the car with a hammer.
What? Pour oil and set fire? When the oil is burned out, let's see if the car will be hot or not.
We don't need to go out to breathe. There are oxygen tanks in the car.
If there are only a few assassins, ask the Winged Knights to give you five minutes. When the time is up, take action. Good luck! Life is short! Oh! It should be said that life between heaven and earth is like a white steed passing a gap.
"It should be noon when we arrive. What do we eat?" Li Longji was reviewing memorials and personnel transfers.
"Your Majesty, it's better to eat braised frogs than to listen to frogs. Zhang's village sold them for a season."
Wu Jieyu looked at her son and wanted to eat frogs.
"Send people back to get frogs. Don't catch frogs in the fields. Brother Yi said that the newspaper doesn't introduce how to eat frogs. I'm afraid that everyone will catch frogs."
Li Longji didn't object. He wanted to eat farmed frogs.
Zhuangzi was expanding the breeding of frogs. There were mountains behind it, the Qinling Mountains.
There was no toad oil at this time. It had to wait. Winter was the most precious.
Toad refers to a frog, and a toad is called a toad.
For medicinal purposes, frogs eat seeds and oil, toads take toad cakes, and at the same time put a large piece of beeswax into the toad's mouth, sew the toad's mouth shut, and bury it in the ground during the winter, so that it won't run away.
When spring came, the thread would be removed, and the toad would be released. The toad would definitely be in pain, but he had to put himself first.
"I heard that Zhangsun Xin raised many bees. Are there bee pupae to eat?" Empress Wang looked out of the window. She wanted to eat bee pupae.
"Ask Brother Yi when we get there. If there are too many pupae, eat them. If there are too few pupae, eat them instead." Li Longji did not feel like eating anything at the moment.
The Li Family Zhuangzi had bee pupae. They collected them and used them for medicinal purposes, not as delicacies.
…
"How's the child?" Zhangsun Xin asked when she saw Li Yi land.
Wang Wei, Meng Haoran, and the others all looked concerned.
"Raise it for ten days to half a month. Right now, snakes have a lot of venom and eat well. If it's winter, the venom will be weak.
Fortunately, it was only bitten on the calf of one leg. If it was bitten on the neck, I would still be in trouble.
Oh, I have another disciple. The child who was bitten by the snake. Please take care of him in the future. "
Li Yi explained the situation and smiled. It was a joyous occasion for a master to accept a disciple.
"Gang Rou, is this too hasty?" Wang Wei asked when he heard that the child was bitten by a snake because he picked fruits for Li Yi. Would others risk their lives to try in the future?
"There is a Bo Le in the world, and then there is a horse …" Li Yi said and recited the horse again.
"Good, good essay!" Wang Wei praised.
"Indeed!" Meng Haoran felt that he had the deepest feeling. There were too few Bo Le in the world.
Zhangsun Xin sighed. "People often don't know me."
"Everyone, recite it." Li Yi looked at the three people. I'm done. It's your turn.
The three people: "…"
"Gang Rou, are you saying that the child …" Wang Wei reacted. His head hurt, and he could not recite it.
"You already have a disciple who has a photographic memory." Meng Haoran facepalmed. Were the geniuses of the world worthless?
"I see!" Zhangsun Xin shook his head. He did not want to compete. His poetry was not as good as others.
"Photographic memory is actually very simple. With the method of memorizing pictures, you can remember in a short period of time, but you will forget after a while unless you strengthen your memory.
My second disciple was hungry after I finished. He talked to me while eating wontons. Then he recited it.
Let's go and see what's planted there. "
Li Yi continued to move forward. He had said what he needed to say.
The terrain ahead was low, and there were a lot of gravel.
There were sticks and shelves in the ground. There were cucumbers, eggplants, and cowpeas.
The eggplants were short, and the eggplants did not grow tall. The cucumbers and cowpeas were almost the same height.
"This is the advantage of the terrain. There is a pressure well. If there is not enough water in the soil, it will be filled with water." Li Yi understood the situation at a glance.
Zhangsun Xin smiled. "Actually, you can build a tall water wheel and drive it with the wind to draw the water down."
"Is it suitable for all the soil of the same kind? How much does a water wheel cost? It can't be driven by the wind for long, and it can't be used for other purposes, such as grinding rice. "
Li Yi looked at the current terrain and watering situation and suddenly had a new idea.
"I want to draw." Li Yi looked at Qing Song.
Qing Song looked at Huang Bai and Ge Yan. You two are pulling the box. Hurry up.
Ge Yan and Huang Bai propped up the box and turned it into a platform.
"I used to think that some operations cost too much. Drip irrigation technology. Now I think I thought too much. The bamboo and labor of our Tang dynasty are not worth much. "
Li Yi began to draw. One bamboo tube after another. It was watertight. So what if some water leaked out when placed in the ground?
The bamboo tubes were connected to each other, and a higher position was the top half of the bamboo tube.
A hemp rope was stuffed in. The hemp rope would absorb water, and the other side of the hemp rope would be placed at the roots of the crops.
When water flowed through the bamboo tube, the hemp rope would absorb water and supply water to the roots of the crops. This was the most primitive drip irrigation technology.
"Should I apply for a patent? Why am I so smart? The people of our Tang dynasty must remember to increase my lifespan! "
Li Yi muttered as he drew the drawing of the bamboo tube and hemp rope drip irrigation technology. The higher position was the pressure well, and the water would flow out.
Now sand was directly irrigated in furrows. The front part was already soaked, and the water would seep into the back part.
Connecting bamboo tubes seemed to be expensive, but no matter how expensive it was, could it be more expensive than automatic iron tube drip irrigation?
The labor cost was low in the Tang dynasty. Bamboo tubes were much cheaper than iron tubes.
Not to mention the whole bamboo tube, it was also fine to cut it in half. How much water could be evaporated in a short time?
"The terrain is gradually downwards. Even if the angle is very small, as long as the water flows downwards, this method will work."
Li Yi finished drawing and threw the pencil away.
The people around, even the palace maids and eunuchs, understood. They looked at Li Yi after they finished looking at the drawing.
"Is this the peerless National Scholar?"
The man who raised the bees had been beside them. His eyes could not see clearly, but he understood.
At this moment, he was even more excited than the others. Wang Wei and the others were officials. They considered the livelihood of the people. They naturally accepted and were used to Li Yi's methods.
It was normal for Li Yi to come up with a good idea! Otherwise, why would we follow you here?
The beekeeper was not used to it. He wanted to cry. How could Li Dongzhu of the Tang dynasty be so smart? There was no way.
