The scene inside the greenhouse is in stark contrast to the outside.

It's mid-September now, and winter is about to begin.

Even though Chang'an City is located in the Central Plains, which is not too north, the temperature outside is now below ten degrees.

But in the greenhouse, the temperature is at least 278 degrees, which is no different from midsummer.

How did Li Chengqian do it?

Could it be that he has really become a god?

Seeing the surprised appearance of these three people.

Li Chengqian smiled proudly: "Does your father want to come and see with his sons?" ”

"Hmmm......"

Hearing Li Chengqian's words, Li Shimin finally came back to his senses.

For the sake of face, he hurriedly put away the look he had never seen the world just now, and said arrogantly: "Lead the way ahead." ”

Li Chengqian did not hesitate, and took Li Shimin to the depths of the greenhouse.

First of all, the closest to the gate is the corn planting area, then the peanut planting area, the pepper planting area, the cantaloupe planting area, the watermelon planting area......

In the end, Li Shimin couldn't suppress the surprise in his heart.

He turned his head to look at Li Chengqian and asked, "You kid tell me the truth, where did these things come from?" Who taught you how to build this greenhouse? ”

Hearing this, Li Chengqian suddenly changed his bitter face and said: "Father, I really can't say this......

"Why?"

"There's no why."

Hearing this, Li Shimin's face suddenly darkened: "Can't even tell me?" ”

"I can't."

Li Chengqian still shook his head.

Seeing him like this, Li Shimin narrowed his eyes.

The next moment, a three-foot-long ring ruler had already appeared in his hand.

"To say or not to say?"

Seeing this, Li Chengqian subconsciously covered his buttocks and took a step back with a panicked face.

"I promised people that I would never say anything about it."

"Father doesn't want his son to be a treacherous guy, right?"

has been a father and son with Li Chengqian for so long.

Just by looking at his expression, Li Shimin could roughly guess his psychology.

Under normal circumstances, as long as he shows the ring ruler, Li Chengqian will definitely admit it.

And if he didn't admit it, then even if he really beat him, it would be useless.

Therefore, Li Shimin didn't force him anymore, but sighed lightly and said: "It's a pity that such a talent can't be used by my Datang......"

See his melancholy look.

Li Chengqian snickered in his heart.

Li Shimin would never have thought that the talent in his mouth was standing in front of him.

……

Wait until you come out of the greenhouse.

Li Shimin asked Li Chengqian to get into his carriage.

He asked straight to the point: "In your opinion, how long will it take for your plan to be realized?" ”

Li Chengqian thought for a while and said: "It takes at least half a year to cultivate seeds and seedlings. ”

"If nothing else, I will be able to take people to the Northern Desert early next year."

"Huh?"

Li Shimin's face was full of inexplicability: "You still plan to take people in person?" ”

"Of course."

Li Chengqian said: "Father, these things are all cultivated by me, and no one understands them better than me." ”

"And it is very difficult to cultivate these crops, once a seedling or a seed is wasted, it is a great loss for us Datang."

"So I'm sticking to my own ideas when it comes to this."

Looking at Li Chengqian's determined eyes, Li Shimin chuckled.

"When you went to the Northern Desert before, you didn't still complain about being tired."

"This time, I took the initiative to ask to go, and I really grew up......

Li Shimin rubbed Li Chengqian's head: "In this case, I won't say anything more." ”

"It's up to you to take care of this, and if you need it, just come to me."

Hearing this, Li Chengqian's eyes lit up: "Really? ”

Who knows, Li Shimin added: "Except for money, you can find me." ”

When these words came out, Li Chengqian's eyes immediately rolled his eyes.

He should have been Li Shimin, an old man who was picking and searching, would never give himself any benefits.

The reason why he said this was simply to be polite to himself.

The father and son chatted a few more words about the matter.

Li Chengqian stood up and said, "If my father is fine, I will leave first, there are still many things to be busy." ”

"Hmm."

Li Shimin nodded, and then instructed: "No matter how busy you are, don't forget to enter the palace to greet your mother." ”

"Don't worry."

Li Chengqian smiled and said, "I won't forget to say hello to my father." ”

After saying this, Li Chengqian threw a silly smile at Li Shimin, and jumped out of the carriage.

See the way this guy runs.

The corners of Li Shimin's mouth slowly raised.

As he gets bigger and bigger, Li Shimin can see more and more of his shadow when he was a child from him.

Li Shimin sighed lightly, and then instructed the horseman: "Let's not go back to the palace first, let's go directly to Da'an Palace." ”

……

Inside the Daan Palace.

The two generations of emperors of the Tang Dynasty, Li Shimin and Li Yuan, sat in the garden, enjoying the last scenery of late autumn.

Li Shimin looked at the falling leaves, pursed his lips and said, "What does my father think of Erlang, the emperor, doing?" ”

"It's great."

Li Yuan said without thinking: "Since you ascended the throne, the world has been stable and the people have been rich. ”

"Even the Northern Desert and Western Regions that have plagued the Central Plains for thousands of years have been completely eradicated."

"Don't talk about it, just say these two feats, and you will already be unprecedented."

Hear that.

Li Shimin was a little ashamed.

He scratched his head a little embarrassed and said, "I'm a little embarrassed when my father said that. ”

"I'm telling the truth, what's there to be embarrassed about?"

Li Yuan shook his head and smiled: "But while praising you, I also want to talk about my grandson." ”

"I heard that he stopped you from standing up to the matter of the Metropolitan Protectorate, right?"

"Father has heard about it?"

In this regard, Li Shimin is still a little proud.

After the Tang Dynasty eliminated the Turks and Tuyuhun, they included these two places in the territory of the Tang Dynasty.

Originally, according to Li Shimin's intention, he planned to build a capital protectorate in Tuyuhun and the Turkic capital to manage this land.

Protect the mansion, take charge of Zhufan, comfort the conquest, and punish the merits.

On the surface, the Metropolitan Government would not spend much money and could govern a large area of land.

It can be described as fame and fortune.

But in fact, this is to build the foundation of the dynasty of the Imperial Palace.

If one day, the strength of the land under the jurisdiction of the Metropolitan Protectorate increases dramatically, then the Metropolitan Protectorate will be useless.

So before this matter was decided, it was stopped by Li Chengqian.

He gave two reasons.

First, the northern people moved south, the western people moved east, and nearly half of the old Turkic people and Tuyuhun settled in the Tang Dynasty and became the children of the Tang Dynasty.

Why can't these two lands be controlled in accordance with the etiquette laws of the Tang Dynasty?

Second, although on the surface, the establishment of the Metropolitan Protectorate in a certain place means that this land belongs to the Tang Dynasty.

In reality, however, the establishment of the Imperial Protectorate was only a nominal jurisdiction.

In the event that one day a more powerful regime emerges, then the Metropolitan Protectorate will be equivalent to none, and on the contrary, it will cost manpower and material resources in vain.

If so, why build it?

In the end, Li Shimin personally ordered the Northern Desert and Tuyuhun to be incorporated into the territory of the Tang Dynasty, becoming the Xihaidao and Mobei Dao of the Tang Dynasty.

Li Yuan said with a smile: "My grandson does have a very unique talent in politics, and I can close my eyes with peace of mind if the Tang Dynasty is handed over to him......
