Time flies, with the drawings brought by His Majesty, the staff of the Ministry of Engineering are very powerful this time, and it only took less than 10 days to build a waterwheel.

After the waterwheel was built, it was arranged to the rivers around Chang'an City, and the water pushed the waterwheel, running non-stop.

Until the water is pushed to the top and flows down.

The experiment was successful, and the Minister of Industry rushed to the palace non-stop and reported to His Majesty.

When Li Er heard the news, he quickly came to the river, and when he saw the results of their development, his face was full of smiles.

Officials at the Ministry of Industry began to pat on the back again.

Li Er glanced at them, if it was a small waterwheel, he had already arranged the drawings, but they still couldn't build it.

I absolutely suspected that the court was raising a bunch of waste, so I simply degraded all of them.

Fortunately, this time, they did not disappoint themselves and received their own praise!

As soon as Li Eryi gave the order, he printed a large number of drawings and began to dispatch them to various state capitals and counties, arranging manpower to build them.

Time flies, time flies.

Under the expectation of everyone, spring passed quietly.

However, during this period of time, the waterwheel came out of the court and was built and installed in the state capitals and counties of Chang'an City.

Some villages have also used waterwheels, and the input of this waterwheel has made all the people chant again and again.

Thank you to the court, thank you, Your Majesty.

Some of the terrain is relatively low, and water can be brought over for irrigation.

Some of the terrain is relatively high, and everyone gives full play to the wisdom of the Chinese people, going up the mountain to cut bamboo, splitting the bamboo in half, hollowing out the middle, tying it together, and picking it up and dropping it off one by one.

These bamboos are joined together to form a water pipeline.

Although the amount of water coming out of a row of bamboos is a bit small, when more than 10 rows of bamboos are lined up, the water flow is very large, enough for everyone to have a good irrigation.

In addition to the waterwheel, good news came one after another in the surrounding counties, and the deep well excavation was also a great success.

It's just that in the process of excavation, there are inevitably joys and sorrows.

In the process of excavation, many counties collapsed, killing many people, making many people feel a little indignant.

It's just that because of the pressure from the government, I can only continue to endure it.

When he knew about this, Li Er asked someone to contribute money to the treasury and reward these stoned people with some money as a consolation.

As an emperor, this is the case, and sometimes you have to face such difficult choices.

If things are done too well and the people are dedicated to the people, the people may still not appreciate it.

If you don't do it well, be a brutal emperor, don't show compassion for the people, don't show compassion for the people, and the people will explode in the end.

But now I have to think about the overall situation, and today's preparations are just right, there is no fault!

In addition to these, the good news came from the northern Turkic territory one after another.

Of course, in the midst of good news, there is also news of failure.

Because of His Majesty's clever calculations, the soldiers of Datang can be described as victorious in a hundred battles.

In such a situation, there are many soldiers who are proud of their hearts, and they have won the battle, and they have not followed the process given by His Majesty, and they have rushed forward.

As a result, the steps of the two teams were disrupted, but fortunately, the soldiers of the other team arrived quickly and eliminated the enemy in one fell swoop, so as not to cause a chain reaction.

Otherwise, a chain reaction will occur, which will cause the strategy designed in advance to increase the unknown.

Seeing this news, Li Er slapped the table vigorously and scolded angrily.

It is really unreasonable, although they will be outside, and the monarch's order will not be affected, they can also make corresponding strategic adjustments in response to the various situations that are happening ahead.

However, as long as the war is fought according to the line set by itself at that time, it will definitely be won.

If it was because of the pride of this part of the people, they did not proceed according to the plan and disrupted the layout of the entire battlefield, Li Er decided that no matter who they were, they would be severely punished.

Fortunately, this time it did not mess up the layout, let it make up for it, and if it commits it again, it will definitely be dealt with by military law.

Time continues to move forward, and since the beginning of summer, the weather has become hotter and drier.

"Uncle Zhao, do you think there will really be a big drought this year?"

Li Chengqian, who came to study in Zhaojiazhuang, can also clearly feel that this has been the beginning of the summer.

Just a few days ago, there was a heavy rain, and this heavy rain was very timely, and the people cheered.

But after the heavy rain, the whole sky was clear, cloudless, and the sun was scorching and poisonous, but there was no sign of wanting to rain.

"The great drought is a historical necessity, and it cannot be solved by our own people.

All we can do is to conform to the will of God and save ourselves in advance! ”

Hearing what Zhao Mu said, Li Chengqian muttered in a low voice.

"Uncle Zhao, we

Conform to the will of God and save ourselves in advance, can't we really go against the sky? ”

"Hahaha, good boy, I have learned more and more knowledge in my Zhuangzi, and I know that I am going against the sky?"

Li Chengqian smiled slightly.

"Uncle Zhao, I'm just kidding,

I don't dare to go against the sky. ”

As the crown prince, the future emperor, if he goes against the sky, isn't this just thinking about dying in his own hands?

I don't dare to think about it.

"Hahaha!"

Seeing him like this, Zhao Mu laughed out loud.

"What does it mean to go against the sky? What does it mean to go with the sky?

Could it be that it was because if it didn't rain, my people would have to wait stupidly in place and wait for death?

If such a thing is called walking in accordance with the heavens, it would be foolish for me to say.

We can start to save ourselves, for example, if there is less water in the north, we can divert water from the south to the north.

There are many floods in the south, so reservoirs are built during the dry season, dams are reinforced, and rivers are dredged.

In this way, if there is a catastrophe, it can be endured, is it possible to achieve it because the people save themselves, so this is called going against the sky? ”

Li Chengqian thought for a moment, as if he understood or not, it seemed that he understood a lot, but there were also a lot of people who didn't understand!

"You have to know that technology develops to a certain level, and we can change the sky.

We can take artificial rain, and if there is going to be hail in the sky, we can break up the hail in advance. ”

This time, Li Chengqian learned to answer!

"Uncle Zhao, Uncle Zhao, I still know.

If there is thunder or lightning in the sky, we cannot hide under the trees.

Because if we hide under a tree, it will increase the probability of being struck by lightning.

And at that time, we can install lightning rods.

In this way, if there is a lightning strike, it will also hit the lightning rod directly.

Just like the pointed things standing on the top of the houses in Zhaojiazhuang, that is the lightning rod.

The other end is connected to the ground, and the thunder is directly introduced into the ground, am I right? Uncle Zhao? ”

"Hahahaha, you've been studying for so long, and you've already learned to answer?

That's right, you have to understand that everything can be answered with science.

Even if there are some things that science can't answer at the moment, it's because science hasn't developed to that point.

In the future, you can also answer all the questions! ”

"Uncle Zhao, I know."

In fact, what we have to do is to grasp the laws of nature and live in peace with nature.

Li Chengqian shook his head.

Uncle Zhao, I don't understand this.
