Chapter 1681: Stupid Disciple's Random Thing

Love you, come to Tang Dynasty with the system

"You find an excuse to run out and play, want to abandon me? Humph! You are so cruel." Li Longji muttered.

Yesterday, the imperial guards reported back that Li Yi wanted to build a bridge over the Yellow River. He didn't think much of it, just build it!

Who would have thought that the prime ministers would go out together to Lantian County early in the morning.

You all go, and I am bored in the manor? How can this be!

Let's go, all go, the distance is not very far.

If there is an emergency in other places, the imperial guards will come to report. There will be no one who wants to attack Chang'an, right?

If there is indeed a group of enemies suddenly attacking Chang'an, we must find Brother Yi.

Like Liu Jieyu, Wu Jieyu, Queen Wang and others, they are happy and take their children out to play.

In the past, traveling was a big deal, and people were afraid of being assassinated.

Nowadays, if someone wants to assassinate, it is still unclear whether they can damage the car.

Let alone swords, bows and crossbows, let's see how many swings it takes to smash the car open with a sledgehammer?

What? Pour oil on fire? Wait until the oil is gone, and see if the car will get hot?

We won't go out to breathe, there are oxygen tanks in the car.

If there are only a few assassins, let the Yulin Flying Cavalry give you five minutes, and when the time is up, do it, come on! Life is short! Oh! It should be said that life is like a white horse passing by in the gap between heaven and earth, it's gone in a flash.

"It should be noon when we get there, what should we eat?" Li Longji was reviewing memorials and personnel transfers.

"Your Majesty, it's better to eat braised frogs than to listen to the frog sounds. Zhangjia Village has sold them for a season."

Wu Jieyu looked at her son and wanted to eat frogs.

"Forest frogs, send someone back to get them, don't catch those in the field. Yidi said that the newspapers don't introduce how to eat frogs, and I'm afraid everyone will go to catch frogs."

Li Longji didn't object, he wanted to eat farmed forest frogs.

Zhuangzi was expanding forest frog farming, and there were mountains behind him, the Qinling Mountains.

There is no toad oil at this time, you have to wait for it, it is most precious in winter.

Toad refers to frogs, and toads are called toads.

For medicinal purposes, eat the seeds and oil of frogs, and take toad venom from toads. At the same time, put a large piece of beeswax into the mouth of the toad, sew the mouth of the toad, and bury it in the soil during the winter. Watch it and don't run away.

Wait until spring to remove the thread, take it out, and let the toad go. The toad will definitely feel pain, but people should put themselves first.

"I heard that Changsun Xin raised a lot of bees. Do you have bee pupae to eat?" Queen Wang looked out the window and wanted to eat bee pupae.

"Go to the place and ask Brother Yi. If there are more pupae, eat them, and if there are fewer pupae, replace them." Li Longji doesn't want to eat messy things now.

There are bee pupae in the Li family's farm. Collect them for medicinal purposes, not for food.

...

"How is the child?" Changsun Xin saw Li Yi landed and stepped forward to ask.

Wang Wei, Meng Haoran and everyone else showed a look of concern.

"Raise it for ten days or half a month. Now the snake has more venom and eats well. If it is winter, the toxicity will be weaker.

Fortunately, it was only bitten on the calf of one leg. If it was bitten on the neck, I would still be rescuing it.

Oh, I have another disciple, a child bitten by a snake. Please take care of him in the future."

Li Yi introduced the situation and smiled. It was a great joy for the master to accept a disciple.

"Hard and soft, is it too hasty?" When Wang Wei heard that the child was bitten by a snake because he picked fruits for Li Yi, he accepted him as a disciple. Will others risk their lives to try in the future?

"There are Bole in the world, and then there are thousand-mile horses..." Li Yi recited the horse again.

"Good, good article!" Wang Wei praised.

"Indeed!" Meng Haoran felt that he was the most touched. There were too few Bole.

Chang Sun Xin sighed: "People in the world often don't know me."

"Everyone, recite it." Li Yi looked at the three people. I'm done. It's your turn.

Three people: "..."

"Gangrou, you don't mean that child..." Wang Wei reacted, his head hurt, and he couldn't recite it.

"You have a great disciple who can remember everything he sees." Meng Haoran covered his face. Are geniuses in the world worthless?

"So that's it!" Changsun Xin shook his head. He didn't want to argue. He couldn't write poems as well as others.

"It's actually very simple to remember everything you see. There is a picture memory method. You can remember it for a short time, but you will forget it later unless you strengthen this memory.

My second disciple was hungry after I finished speaking. He ate wontons while talking to me, and then he recited it.

Let's go, look forward, what is planted over there?"

Li Yi said and continued to move forward. He said everything he should say.

The terrain ahead is low, and there are many gravels.

There are sticks inserted in the ground, and there are cucumbers, eggplants, and cowpeas.

The eggplant rack is low, and the eggplant vines themselves can't grow high. The cucumber and cowpea racks are almost level.

"Here we take advantage of the terrain, there are pressure wells, if there is not enough water in the soil, we can pressurize water?" Li Yi knew the situation at a glance.

Chang Sun Xin smiled: "In fact, we can build an elevated water truck, driven by wind, to draw water downstream."

"Is it applicable to all similar soils? How much does the elevated water truck cost? It is driven by wind, it can't last long, and it is difficult to use it for other purposes, such as grinding rice and flour."

Li Yi looked at the current terrain and irrigation situation, and suddenly had a new idea.

"I want to draw a picture." Li Yi looked at Qingsong.

Qingsong looked at Huang Bai and Ge Yan, you two are pulling boxes, hurry up.

Ge Yan and the others propped up the box to make it a platform, and took the things inside to it.

"I used to think that some operating costs were too high, drip irrigation technology. Now I think I've thought too much, our Tang bamboo and labor are not worth money."

Li Yi began to draw, one bamboo tube inside another bamboo tube, no need to cover it tightly to prevent water from leaking, put it in the ground, what if it leaks a little?

The bamboo tubes are connected to each other, and a hole is drilled on the top of half of the bamboo tube at the higher position next to it. UU Reading ｗww.uukanshu.net

Put in a hemp rope, which will absorb water, and the other side of the hemp rope is placed at the root of the crop plant.

When water flows through the bamboo tube, the hemp rope absorbs water and supplies water to the roots of the crop. This is the most primitive drip irrigation technology.

"Should I apply for a patent? How can I be so smart? The people of our Tang Dynasty remember to increase my life span!"

Li Yi muttered as he drew the technical drawings of the bamboo tube hemp rope drip irrigation. The high ground is the well press, and the well water flows out.

Now the sandy land is directly irrigated with ridges and furrows. The front is soaked, and the back still seeps to the position.

The bamboo tube connection seems to be costly, but no matter how high it is, can it be higher than the automatic iron pipe drip irrigation?

The labor cost in the Tang Dynasty is low, and bamboo tubes are much cheaper than iron pipes.

Not to mention the whole bamboo tube, it is also OK to split it in half. Once the water is pressed on the top, how much water can evaporate in a short time?

"The terrain gradually goes down, even if the angle is small, as long as the water flows to the lower place, this method will work."

Li Yi finished drawing and threw the pencil away, generous!

People around, even the palace maids and eunuchs understood, they looked at Li Yi after reading the picture.

"Is this the unparalleled national talent?"

The man who kept bees had been beside him, his eyes could not see clearly, but he heard clearly, and his heart was bright.

At this moment, he was even more excited than others. Wang Wei and others were officials, considering the people's livelihood, and they naturally accepted whatever method Li Yi came up with, and they were used to it.

It's normal for you, Li Yi, to come up with a good idea! Otherwise, why did 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 is no way he can't do it.
