After a long time, he sighed and looked at Li Shimin and said, "So, I don't like dealing with smart people. Because I don't have the sense of accomplishment at all, any thoughts will be guessed and seen through by smart people."

Li Shimin laughed and said proudly: "Just like you, a brat, do you want me to be amazed at you? If you talk about methods, you are far from the same. I want to shock me, and practice again in the next life."

Gu Tianya said a few times and refused to comment.

He no longer continued the topic, but picked up a shovel and shoveled it heavily on the ground, then leaned down to watch, and sighed inexplicably.

Seeing that he was like this, Li Shimin also picked up the shovel again. As the former general of the Tiance Mansion of the Tang Dynasty, Li Shimin was much stronger than Gu Tianya in both force and physical strength. However, when the emperor shoveled heavily to the ground with a shovel, he suddenly sighed inexplicably.

After sighing, he seemed to remember something, so he hurriedly glared on the shovel with his feet, which made the shovel sink a little more, but unfortunately half of it was still left outside.

Gu Tianya shook his head and smiled bitterly, "It's useless, this place is so hard."

Li Shimin frowned.

The two of them looked at the ground silently.

...

After a long time, Gu Tianya slowly straightened his waist from the ground and said in a serious manner: "Second brother, have you seen it? This is a headache..."

Li Shimin's face was also solemn, and he nodded involuntarily and said, "It's really a headache. Whether it's you or me, we both used a shovel to shovel the ground with a shovel. Although we used a lot of strength, the shovel was only half a foot into the soil. In this way, it seems that it is not easy to open up this land..."

Gu Tianya's straight waist bent down again.

Then, the action of bent over turned into squatting.

After squatting down, he directly used his hands to pick the soil. After plucking for a long time, he pulled out a large handful of grass roots from the soil.

Li Shimin was a little curious, and subconsciously squatted down and asked, "What are you doing?"

But Gu Tianya grabbed the grass roots and said with a heavy expression: "This is the root of the thatch..."

"The roots of thatch?" Li Shimin was a little puzzled.

Although he was determined to be a good emperor who loved the people as much as his son, he was born in a wealthy family after all, so even if he cared about farming, unfortunately he didn't understand some farming matters at all.

Fortunately, Gu Tianya saw that he was puzzled, so he raised the grass roots and explained: "The root system of thatch is very developed. Every winter, the thatch will freeze and rot, but the root system below is deep in the soil. No matter how severe the cold is, it cannot destroy the root system..."

He said, and then said: "But this thatch is a perennial plant. As the years grow, the root system will become more and more developed. It is like a dense net, hidden deep in the soil and waiting for spring. Once spring comes, these root systems will immediately breed countless thatch, seizing crop nutrients, and farmers can't help them."

Li Shimin looked thoughtful and said in a deep voice: "I seem to understand that the so-called land reclamation means clearing the roots of these thatchs. If the roots cannot be removed, the land cannot grow even if it is planted with crops. It means that it is still a wasteland..."

Gu Tianya nodded and said, "That's exactly!"

Li Shimin looked into the distance from afar, looked at the endless wasteland, frowned and said, "If according to what you said just now, the older the thatch root system is, the more developed it is, and the years of desolation in the Youyun states, wouldn't it mean that these lands are full of thatch roots?"

Gu Tianya nodded again, slowly repeated a sentence he said not long ago, and said, "It's like a dense net."

Li Shimin frowned and said, "What should I do?"

Gu Tianya took a deep breath and said in a deep voice: "The only way is to turn the soil deeper many times. Every time it is deeper, you must clear out the grassroots that have been turned out, and then use this clumsy method to cycle it over and over again. Only when the number of grassroots is reduced to the extreme can the process of land be considered to be completed. At that time, wasteland can barely be considered a field."

The so-called land reclamation means clearing the grassroots in the wasteland. Since ancient times, there is indeed only one way to clear the grassroots, which is to keep turning the soil deeper like Gu Tianya said just now.

Although he gave the answer, Li Shimin frowned even more and said, "How deep should he turn it into?"

Gu Tianya did not answer directly, but squatted down again, staring at the dirt and said, "The land on Youyun has not been cultivated for many years, and the thatch roots in the dirt are growing deeper and deeper, year after year, maybe it will turn three feet into the ground." The fastest update is mobile::

Li Shimin was shocked and subconsciously said, "Turning three feet into the ground? How huge is this effort?"

The emperor looked at the shovel in his hand, and his tone became obviously worried, saying, "We used the shovel to test the ground, but we used so much effort to shovel a foot into the soil. Wouldn't that mean that the people have to put in three or four times the effort to get three feet deep? But how can the people's physical strength be compared with you and me? We can eat full every meal, but have the people ever eaten once?"

Gu Tianya sighed softly and murmured: "Yes, how have the people been full before? How can people who cannot eat enough for many years compare to our strength? But even those who eat enough for many years, who have used such great strength just now, but they didn't shovel all the shovels into the soil..."

He said, and then continued to murmur, "So, you can only use a plow. If you want to use a plow, you must have a bull. However, the land we want to open up for the first time is more than two million acres."

How much plough does this take to be enough?

How many bulls do you need?

Plowing is not difficult to solve, just encourage blacksmiths to work hard to build, but what about cows? The most precious agricultural livestock of this era is cows.

Gu Tianya suddenly stood up from the ground, and a bright light suddenly flashed in his eyes. He looked towards the north, and there was an extremely vast grassland.

It took a long time to hear his murmur and said with a slight point: "It seems that we have to find a way to get a cow from the Turks again."

Li Shimin next to him was stunned at first, then his eyes flashed with gleam, and he said in a deep voice: "We do need Turkic cows!"

As for the Turks who are unwilling to give them?

Neither of the two men continued to say...

It doesn't matter if you don't want to give it to it.

I always think of ways to make them willing to give it!

Whether Li Shimin or Gu Tianya, both of them are extremely xenophobic. For the foreign tribes on the grassland Turks, the two never thought of making friends.

In fact, it is not impossible to make friends.

Unless you give me countless bulls.

If you don't give it to me, you won't be able to make friends...
