Chang'an is prosperous.

Although Chang'an at this time could not be compared with the rule of Zhenguan or Chang'an in the Tang Dynasty, the four seas were peaceful, Chang'an was thriving, and there were already some signs of prosperity.

After Li Shimin returned to Chang'an City, he rode directly to the palace.

Entering the imperial study, the crown prince Li Jiancheng was reporting some government affairs to Li Yuan, and when he saw Li Shimin coming, Li Yuan immediately put down the folds sent by Li Jiancheng and asked: "Shimin, enter the palace at this time, but what is the matter?" ”

Li Yuan's attitude towards Li Shimin was good, the prince frowned slightly, and he didn't like it in his heart, but he didn't show anything at this time, just stood aside calmly.

For so many years, he has already trained the city government.

Li Shimin said: "Father, the emperor, and the sons and ministers urged the people to irrigate the land, which is quite effective, but now the men everywhere are not prosperous, and they simply rely on manpower, but I am afraid that they will not be able to irrigate thoroughly." ”

Li Yuan also knows this situation, since the founding of the Tang Dynasty, the war has not stopped, many men have died on the battlefield, how many can be engaged in farming?

Li Yuan's face was sad, and Li Shimin continued: "But don't worry, father, someone has presented a drawing of an automatic waterwheel to his son, as long as the waterwheel is made according to the drawings, no manpower is required, and the waterwheel can automatically pump water for irrigation. ”

"Oh, and such a waterwheel?" Li Yuan was curious, and took the drawings over to take a look, but the drawings were more cumbersome, and he had never done craftsman work, so he couldn't understand after reading them, so he returned them to Li Shimin, and said: "Okay, if this waterwheel can really irrigate automatically, it is indeed a blessing for my Datang, and you can look at this matter." ”

Li Shimin bowed his head and was about to respond, but at this time, the prince next to him suddenly stood up: "Father, the waterwheel that can be automatically irrigated without manpower, the sons have never heard of it, this must be someone who wants to take advantage of the opportunity to make profits, like such opportunistic people, should be killed to warn the world." ”

Li Jiancheng's expression was calm, but in his words, he was very vicious, Li Yuan didn't like it, frowned slightly, and Li Shimin was here, but the corners of his mouth twitched slightly.

"Big brother, the person who donated the drawings didn't ask for anything, so how could he take the opportunity to make a profit? What's more, this automatic water wheel is indeed feasible, so what is the opportunistic shortcut? Just because you haven't seen it doesn't mean you haven't. ”

Li Shimin naturally knew what the prince meant, when the Tang Dynasty had just been founded, the world was undecided, and the two fought everywhere, but they had no intention of competing for the throne.

But now that it is the sixth year of martial arts, and the world's heroes have gradually been pacified, they naturally put their energy on the inside.

In the past two years, in order to compete for power and profit, the two have clashed a lot.

Some time ago, the prince was responsible for sacrificing and begging for rain, but he didn't ask for it, and now he Li Shimin is responsible for persuading the people to irrigate.

How could the prince possibly watch himself succeed?

After Li Shimin's words, the crown prince Li Jiancheng's expression moved slightly, and then he looked at Li Yuan and said: "Father, the matter of irrigation, the labor and wealth of the people, my Tang Dynasty has just stabilized, and I can't afford it, so I should continue to sacrifice and pray for rain, for the sake of my Tang people, the sons are willing to fast from today until they ask for rain." ”

Li Jiancheng is very aware of the current situation in the Tang Dynasty, the household is not rich, and he also needs food, grass and military pay to fight, and his father has been a little poor and extravagant recently. If Li Shimin wants to build a waterwheel, he must spend money, and if he spends the money of the waterwheel, he will not have the money that his father enjoys, so for his own sake, his father should be biased towards himself.

After all, the sacrifice was very simple, it didn't cost too much gold and silver, and he also played the emotional card.

Sure enough, as soon as Li Jiancheng said that working hard and hurting money, Li Yuan suddenly felt distressed, the money is getting less and less, and it is inconvenient to spend it by himself, how can this work?

Seeing that Li Yuan was about to change his mind, Li Shimin was a little anxious, and said: "Father, only when the people irrigate the land, can the grain yield be high, and we can have grain and grass to enrich the households, and now it is only to irrigate the crops near Chang'an City, and it does not cost much. ”

Li Shimin said a little bit of truth, Li Yuan thought about it, and nodded: "Shimin is reasonable, so let's do it first, if it is feasible, first irrigate in the prefectures and counties around Chang'an City, and then when my Datang is rich in the future, it will be implemented throughout the country and benefit the people." ”

"Whoa!"

After the three of them finished saying this, the matter of manufacturing an automatic water wheel was settled, and Li Shimin hurriedly went back to summon craftsmen to be responsible for manufacturing according to the drawings, Li Jiancheng did not like it, but he did not lose confidence.

He felt that the situation of the automatic water wheel was too ridiculous, and how could it be possible to pump water for irrigation automatically without human labor?

So he thinks that what he has to do now is just to find some officials in the DPRK and China, and after this matter fails, he will ruthlessly join Li Shimin.

--------------

After the Guining banquet was over, Qin Tian and Tang Rong stayed in the Tang Mansion for a while, and then went back directly.

As soon as the two of them got into the carriage, Tang Rong, who was holding Qin Tian's arm, immediately let go, and her expression was even more serious than before.

This can confuse Qin Tian.

I thought that I had avenged Tang Rong today, so Tang Rong had to change her opinion of herself, not to mention going directly to the cave room, but it shouldn't be a problem to let yourself take advantage of it or something.

can look at Tang Rong's appearance, as if she dislikes herself very much, and she has a bit of the meaning of crossing the river and demolishing the bridge.

Qin Tian was very puzzled, he was so good, and he was Qin Qiong's righteous son, the daughter of those powerful people in Chang'an City, I was afraid that he would have to think about himself, this Tang Rong was good, and directly gave himself a stinky face.

"Madame, is you satisfied today?" However, although Tang Rong was cold, Qin Tian decided not to worry about her, his wife was too concerned about what to do.

Tang Rong snorted: "Let me ask you, did you write the general's expedition?" ”

"yes." Such a good poem, Qin Tian must admit it.

Tang Rong snorted again and asked, "That song Daming Lake, Minghu Da was not written by you?" ”

Qin Tian frowned slightly, secretly feeling that something was wrong, but it seemed that this matter could not be pushed away, and in the end he could only respond stubbornly: "I wrote it." ”

Seeing Qin Tian admit that the two poems were written by himself, Tang Rong's expression suddenly tightened, and he felt very uncomfortable, both poems were written by Qin Tian, so he really didn't want to marry himself.

couldn't help but feel a grievance in Tang Rong's heart, don't turn your head and ignore Qin Tian anymore, but Qin Tian was stunned, what is this?

Women are so strange.
