Datang Live Room

Yan Kai provided enough convenience for Bald Qiang’s research.

The rest is up to him.

In fact, many things in Yankai Mall are very advanced.

The reason why he didn't take it out directly was that he felt that the technology tree needed to be added level by level.

Now he has made an electrical equipment and taught the craftsmen how to use it. It is quite simple.

But what about the future?

The likely result is to destroy the creativity of these craftsmen.

Now it is best to slowly guide yourself and form a gradually rising technology tree.

After seeing how long it took Bald Qiang to use it, he discovered that if the projectiles installed in the front can block the iron pipe more tightly, the power will be greater after being launched.

Yan Kai felt that what he did was not wrong.

Many children in New Oriental have also shown their talents in certain jobs.

It actually gave those masters and Yan Kai a lot of surprises.

Children of this era are somewhat different from modern children.

They know better what is their own way out, so they are more focused and attentive when studying.

"Can your trick be replicated elsewhere?" Chu Suiliang asked curiously as he watched a few half-year-old children easily make a curved shaft plow.

Yan Kai thought about it and shook his head and said, "Probably not, because they don't value these craftsmen as much as I do, and they won't give such great support."

If these things are to be implemented, the first thing that needs to be changed may be the status of craftsmen.

In other places, the class of craftsmen is not high. To do this would be to change the class status of the entire craftsman.

This is impossible for many people to accept.

Just the word "face" will make many people jump out and oppose it.

This is true throughout the ages.

"That's a pity!" Chu Suiliang knew that what Yan Kai said was true, so he patted him on the shoulder and said, "The gold mine is almost finished, I have to go and keep an eye on it."

"You can just leave. Your officer is older than me. Why don't you report it to me?"

Yan Kai rolled his eyes at Chu Suiliang.

"Hey, you are so ignorant!"

Chu Suiliang pointed to the field: "Am I reporting to you? I'm reminding you in a roundabout way that when the watermelons in your field are ready, don't forget to send me some to Wendeng County."

"Just hearing you say this food is delicious, I want to see what's going on!"

"I know!" Yan Kai shrugged: "Is it possible to do without your share?"

In Wendeng County, the Tang Dynasty court built a super large mine.

The Tang Dynasty is now in dire straits and waiting to be revitalized, and it is a time when it is short of money.

This gold mine came just in time, and Yan Kai received a huge credit in his credit book.

Even Yu Chang, the magistrate of Wendeng County, was defeated.

He was promoted to the post of chief historian in another state, and the post of magistrate of Wendeng County was left vacant, leaving Chu Suiliang in charge.

Because of Yan Kai's butterfly, Li Shimin and the Tang government are now much more flexible in doing things.

They find that sometimes if they don't follow the so-called "rules", the results will be more obvious.

After sending Chu Suiliang away, Yan Kai returned to his experimental field.

"Dad, will there still be a drought this year?"

After listening to Yan Kai's words, Yan Laoer nodded and said, "It seems so."

It rained several times in the spring, but as the weather gradually warmed up, the rain became less and less. Fortunately, here is the mouth of several rivers.

Although the water level has dropped a bit, it has not stopped flowing.

Water trucks kept bringing water up, and irrigation of the fields was not a problem for a while.

But now there are more people, and more land has been cultivated. Some fields are even higher, and even waterwheels are not that easy to use.

Fortunately, Yan Kai had made some preparations in advance.

The county's pottery workshop produced many glazed pottery pots according to Yan Kai's requirements.

Now they are all sent to those high-lying places.

Yan Laoer also followed. He didn't know anything else, but he was really good at farming.

Seeing Yan Kai directing people to put the pots, he asked curiously:

"Kai'er, you have so many clay pots, but each one can only hold about twenty liters of water, right? It's not very useful!"

Yan Kai smiled and said: "Dad, if we water it normally, these twenty liters of water can't water much ground. But look at these clay pots with so many bamboo tubes connected under them. This is the drip irrigation system I made."

"Drip...irrigation?" Yan Laoer had never heard this word before and said he couldn't understand it.

Yan Kai took him over, pointed to a valve made under the clay pot, and said, "Dad, look, this thing called a valve here is connected between the clay pot and the bamboo pipe with a leather sheath. Only by controlling this The valve, the hole under the bamboo pipe, will slowly let the water flow into the ground.”

"We usually water the crops directly, but the water utilization rate is not very high. Watering like this can save water to the greatest extent."

Yan Kai pointed to the clay pots and said: "A clay pot like this, after being filled, can manage the water for almost ten days."

This kind of statement is simply unheard of. Yan Laoer and some people nearby are a little curious about whether it can be done.

So they squatted in front of the bamboo pipe one by one, watching the small holes in it slowly letting water seep into the ground.

In fact, not only were they confused, many netizens in the live broadcast room were also confused.

"Is it useful to water like this? It took so long for just one drop. It feels like it dripped into the ground and dried up in a short time!"

"Yes, the main purpose of watering is to let the crops absorb water. Is this really effective?"

"Don't worry, this is the method I taught the anchor. This is an improved drip irrigation system based on the fruit tree bottle technology we use in arid areas in the south."

"We have also used this in Yibin. During the severe drought a few years ago, the land inside the fields was dry and cracked. The cracks in some farmland have reached three fingers. We also used this similar drip irrigation system to save 180 people. Thousands of acres of farmland!”

"Hahaha, our Wangtiantian in Luonan Mountain is also irrigated in this way. This should be called water-saving precision root irrigation!"

"I declare that this time, the modern team will get back a point! We can't always be shocked by the ancients. This time it is our turn to shock them again!"

Yan Kai originally learned this thing from netizens. He first made two samples and tried it. He found that one clay pot could manage a small area for more than 20 days, and then he decided to mass-produce it.

Now the pottery kiln in his workshop is still firing such pots day and night.

Because Chun Yunan placed a big order.

Yan Kai has not forgotten that this year is the second year of Zhenguan.

The Zhenguan of this world is because Li Shimin brought the Xuanwu Gate changes ahead of schedule.

It is one year earlier than in history, which means that the severe drought and locust plague that originally occurred in the second year of Zhenguan will come next year.

During this year, Yan Kai planned to fight against the sky to see if he and the tens of millions of live broadcast netizens behind him could beat the sky.
