I have already established my power and prestige, so how did Li Shimin come back to life?

I guess only the queen mother could understand all the grievances. Thinking of this, he sighed heavily for some inexplicable reason, and the sigh was full of helplessness and sadness.

"Although my uncle is my biological uncle, he may not necessarily be thinking about me."

You see, my uncle isn't just the Minister of Works now; he's also the head of the Changsun family, a newly emerging aristocratic family.

Li Chengqian spoke slowly, his eyes becoming deeper.

"I think there will be more trouble over there with Li Tai. My uncle won't help Li Tai get the job. He won't get any benefits from it."

Li Chengqian closed his eyes and kept analyzing various possible situations in his mind, trying to make sense of this chaotic situation.

Zhang Xianhuai was completely bewildered as he listened. He scratched his head and asked in confusion, "Your Highness, but you are the Crown Prince! Is it true that even if His Majesty passes away, you, the Crown Prince, cannot become Emperor?"

"Of course not. I have already secured the throne. I just need to negotiate for my own interests with those ministers from the noble families."

Li Chengqian opened his eyes, a hint of determination flashing in them.

"Don't rush back to Chang'an yet. Let them stir up trouble again. Go and call Mr. Qi and tell him that I have something important to discuss with him."

Li Jiangning glanced at Zhang Xianhuai, his eyes filled with undeniable authority.

Although Zhang Xianhuai looked puzzled, he bowed respectfully to Li Chengqian, then turned around and quickly retreated to call Mr. Qi.

Li Chengqian quietly looked at the crops in the glass-covered greenhouse in front of him, thinking that the output of these things might double next year.

That’s right, what are planted in these greenhouses are the so-called time travelers’ artifacts - potatoes, sweet potatoes, and corn.

Ever since he had some power as a child, he was keen on using his money to build a fleet and go out to sea specifically to search for these high-yield crops.

Sometimes, when he didn't have enough money, he would shamelessly borrow from Empress Zhangsun. Fortunately, these crops were not hard to find; the difficulty lay in the fact that, at this time, these crops did not yield as much as they would in later generations.

But for the current Tang Dynasty crops, they are still shocking.

Just talking about the crop of potatoes, all the time travelers said that it is simple, easy to grow and has a high yield.

But in fact, when Li Chengqian was seriously planting potatoes, he felt that he must have been deceived by these time travelers.

The biggest challenge is soil fertility. Only good farmland during this time can barely meet the fertility requirements of potatoes. Furthermore, there are certain limitations in irrigation conditions and planting techniques.

Every link needs to be carefully controlled. Any slight mistake will seriously affect production.

But fortunately, he was the crown prince, and he was a crown prince who did not rebel or cause any mess.

Apart from liking some strange and tricky tricks, he has no shortcomings.

Li Shimin had him placed in Xianyang early on.

In Xianyang, he established an agricultural department specifically responsible for studying how to increase the yield of these crops and how to adapt to local conditions.

He gathered experienced farmers and knowledgeable scholars from all over the country to join in this great cause.

Thanks to the research of the Ministry of Agriculture in recent years, the yield of these high-yield crops has begun to increase by leaps and bounds.

The potato yield per mu has increased from 500 kilograms at the beginning to 1,500 kilograms now, a threefold increase.

Only Li Chengqian himself knows the hardships involved. Every failure and every attempt is the result of the hard work of countless people.

Corn yield is the lowest among the three crops, but compared with current crops, it performs very well.

Looking at these newly cultivated, thriving seedlings, Li Chengqian couldn't help but squint his eyes.
