“Most of the sediment carried downstream by big rivers is carried away by Hetao, so river management must also control Hetao!”

This Hetao is not the Hetao Plain in the narrow sense, but a "several"-shaped land surrounded by large rivers, reaching Yinshan Mountain in the north, Jincheng in the west, Guanzhong in the south, and Bingzhou in the east.

"In the future, farmland will no longer be cultivated in the Hetao. On the contrary, on some mountainous areas in the west and east, farmland must be converted into forests to consolidate water and soil."

If Liu Yizhen spreads these words, he is afraid that he will be sprayed to death.

The land itself is not enough, and everyone wishes that one acre of land could be used as two acres of farming. How could they be so "luxury" in returning fertile land?

But Xu Zhanzhi had already understood the importance of the Hetao to the entire north when Liu Yizhen talked about the entire river and the entire north.

Knowing is not important, the most important thing is that Xu Zhanzhi seems to have accepted this statement.

He stared at Liu Yizhen with his bright eyes and asked: "Your Majesty, do you want to protect the Loop?"

"It's not that I want to, it's that I have to."

Liu Yizhen did not hide this national policy that he had never told anyone before, but showed it to a young man openly——

"Even if I work hard to open up the Hetao, how many more people can be added? Thousands of households? Tens of thousands of households? Or hundreds of thousands of households?"

"Such a small number of people is too small compared to the entire Central Plains people who are nourished by the river."

"So, why not reduce the number of people here and raise more cattle and sheep?"

Compared with the land consumed by supporting people, raising livestock such as cattle, sheep, and horses will undoubtedly consume much less land and cause much less damage to the land.

"The green storage developed by Tao Gong can even stop livestock from chasing water and grass. In this way, it will not be a fantasy to convert farmland into forest in Hetao."

Qingshu solves the problem of livestock rations.

Champa rice solves people's food rations.

Especially the latter.

Only when everyone has a full stomach can you discuss with everyone a century-old plan or a thousand-year great undertaking. Otherwise, no matter how fancy you talk, you can't stop the cold of hunger.

Xu Zhanzhi fell into deep thought after Liu Yizhen finished speaking.

There is no doubt about it.

Liu Yizhen's words opened the door to a new world for him.

If Liu Yizhen taught Tao Yuanming the knowledge of how to make grain grow from the ground, what he now teaches to Xu Zhanzhi is how to make grain fall from the sky.

No matter how intensively Tao Yuanming cultivates, a flood or a drought may result in no harvest.

On the other hand, the method Xu Zhanzhi learned to control the Hetao was a dragon-slaying technique that could save the food in the entire north!

The young man who was not pedantic quickly thought of this key——

The cultivation in the fields is just a path.

Turning things around is the way to go!

His eyes became hot, he straightened up and shouted: "I want to go to the Loop!"

"What kind of Loop are you going to do?"

Before Liu Xing had time to flutter her wings, she was the first to pull them down. The princess of the empire showed her rare majesty and frightened her child: "I don't object to you coming to learn how to grow a plant, but if you go to the Hetao... Huh huh! No problem."

talk!"

Liu Xingdi is not an ordinary village woman who cannot read Chinese characters. She knows where the Hetao is.

It was a place that had been lost by the Han people for two hundred years, and where foreign barbarians were running all over the place!

Not to mention that there are countless small tribes like jackals wandering there, and if you are not careful, they will knock them down and eat them up.

In addition, there are hostile forces outside the Hetao such as Northern Liang and Northern Wei...

No matter how generous Liu Xingdi was, she would never be able to throw her child into that dangerous land and let him grow up.

But Xu Zhanzhi is the most rebellious grade among teenagers, plus...

Isn’t my uncle the emperor right next to him?

Xu Zhanzhi was no longer as dull as he was in the field just now. He hid behind Liu Yizhen very smartly, hugged Liu Yizhen's thigh and began to shake: "Uncle, my nephew also wants to help uncle share some state affairs! Just help me!"

Liu Yizhen secretly gave Xu Zhanzhi a "don't worry" gesture, and then mustered up the courage to confront Liu Xingdi.

"Woo~"

"Ahem, sister, don't do this."

Liu Xingdi, who looked fierce just now, was crying like a tearful person.

This made Liu Yizhen, who had already mustered up all his momentum, feel like a ball of frustration. He timidly stepped forward to comfort him: "Sister, it won't happen, it won't..."

Liu Xingdi's tears were already welling up, and he said intermittently: "If I were not a doting mother, I would never forget the sad things back then. How could I dare to send my child to the front line again now?"

Sad things happened back then.

Naturally, it was the death of Xu Kui, Liu Xingdi's first wife and Xu Zhanzhi's biological father, on the battlefield.

At that time, Xu Kuizhi was entrusted with the important task of attacking Jingzhou by Liu Yu. He never expected that his boat capsized in the ditch and died in Jingzhou, which indirectly led to the tragedy of Liu Xingdi's life...

Liu Yizhen didn't know what Liu Yu told Liu Xingdi when he sent Xu Kuizhi.

Is it the same as now? She vowed to Liu Xingdi to ensure the safety of her husband (son), but in the end she could only respond with a look of fear and guilt.

Thinking of this, the fire in Liu Yizhen's heart cooled down for the most part.

Although Xu Zhanzhi was excellent, he was not only a citizen of the Song Dynasty, but also the nephew of Liu Yizhen and the son of Liu Xingdi.

Although the Loop has been leveled now, Liu Yizhen dare not pat his chest and guarantee that this land is safe.

If Xu Zhanzhi really had a problem, he would not be able to explain himself even if he went down to see Liu Yu, not to mention that he would not meet Liu Xingdi in the future.

Standing up, Liu Yizhen wanted to comfort Xu Zhanzhi and let him put aside this idea for the time being.

But who knows.

Xu Zhanzhi suddenly puffed up his chest and faced Liu Xingdi without any delicate air——

"Does the mother want to keep her child by her side as a rare animal for the rest of her life?"

"..."

"Gan Luo paid homage to the prime minister at the age of seven, and finally asked for a tassel when he was weak in the army. When Emperor Tianzi and King Hejian were young, they followed Emperor Taizu in the northern expedition to the Central Plains. This is what happened recently. Although the child is not the son of Liu,

But there is also Liu’s blood! This big thing needs to be done by others? Why can’t children do it?”

Liu Yizhen's eyes lit up after hearing this, and his admiration for Xu Zhanzhi became even stronger.

"Besides..."

Xu Zhanzhi finally mentioned the taboo——

"Even if the father is still alive, he doesn't want his child to be just a waste waiting to die!"

When Liu Xingdi heard this, he finally couldn't suppress his emotions and cried even louder: "Zhanzhi!"

For a moment, Xu Zhanzhi also hugged his mother and started crying. Liu Yizhen felt deeply about Liu Xingdi's difficulty and his eyes were red.

Tao Yuanming: "..."

After everyone regained some of their emotions, Liu Yizhen came up with a compromise: "Sister, although Zhanzhi is young, he already has great ambitions... In this way, I will keep Zhanzhi by my side for a few years until the situation in Hetao

After he's stabilized, how about I let him go to the Loop?"

After saying that, Liu Yizhen turned to look at Xu Zhanzhi, with a fierce expression like a little boy who is obeying me.

Xu Zhanzhi nodded fearfully. This regressive move was seen by Liu Xingdi, who burst into tears and laughed: "You kid, do you really follow your father's stubborn temper?"

"Huh? Don't nephews all look like uncles? Sister, don't you think Zhanzhi looks a bit like me?"

"Cheshi! You are looking for a fight!"

"Sister, spare your life! Haha!"

"..."
