The next day, Li Zhi took a group of children from the academy to map the terrain of the surrounding map, including the land acres.

According to the arrangement, no matter how you plant trees, it will not affect the fields.

There are not many paddy fields around Chang'an, but many of them are dry and wasteland.

Most of the paddy fields are on the edges of various rivers.

The so-called eight waters surround Chang'an, and food is planted near the rivers around Chang'an.

Li Shimin sat in the Ganlu Hall, listening to Wang Ding's report.

The news was sent from Goguryeo, and it was also the current situation in Goguryeo.

Li Shimin rubbed his temples tiredly and said, "So my order to truce is useless, right?"

Wang Ding whispered: "The King of Goguryeo has just ascended the throne, and now it needs a war to establish prestige and win people's hearts."

Li Shimin sighed and said, "It's true."

Wang Ding whispered: "It seems that the war between Goguryeo and Japan is still going to be fought. Next year, the envoys of Goguryeo and Japan will come to Chang'an together."

Li Shimin nodded and said, "Let the Ministry of Rites handle the matter between Japan and Goguryeo."

Wang Ding said again: "Your Majesty, Your Highness, King Jin, is surveying and mapping the land, and the Gaoyang Gonggong's main Ministry of Revenue took out a file of land to check the land to plant trees."

Li Shimin looked at the memorial expressionlessly and said, "Lizhi is also out of filial piety, telling the Ministry of Revenue what to do or what to do."

Wang Ding bowed and said, "I understand."

After walking out of the Ganlu Palace, Wang Ding breathed a sigh of relief, and His Majesty said that the Ministry of Revenue would be like what should be done.

Naturally, the Ministry of Revenue’s field book files cannot be taken out for people to read casually.

This is what His Majesty said should do what the Ministry of Revenue should do.

But His Majesty said it was all out of filial piety.

It was also a blow to the Ministry of Revenue.

Wang Ding came to the Ministry of Revenue. At this moment, the Ministry of Revenue was in a mess. It was obvious that Princess Gaoyang had just come here to make trouble.

Several officials from the Ministry of Revenue were tidying up. When they saw Wang Ding coming, they asked, "What do you say to you?"

Wang Ding said: "Your Majesty said what the Ministry of Revenue should do or what it is."

A number of officials from the Ministry of Revenue nodded, how could they easily take out the Tiancai file and file for others to read?

Wang Ding said with a sad look: "It is also out of filial piety. The princes and princesses are sensible and want to plant trees for Queen Changsun, and they are also to fulfill their filial piety."

While talking, Wang Ding looked at everyone's faces, Wang Ding said, "Princess Changle, Princess King of Jin, Princess Gaoyang, Princess Jinyang, Princess Wei, and Princess Shu all want to be filial and are all good kids."

The Ministry of Revenue officials whose expression had just eased was silent again.

If the Ministry of Revenue handed over the land book file, would he offend three princesses and three princes?

Although His Majesty's words are now there, who dares to offend the six royal descendants at once?

Will you still be able to get along in the future?

Wang Ding said slowly: "Although filial piety is the result of your filial piety, you still have to deal with it well. Your Majesty sees it all, so I will bring my words."

After Wang Ding left, it was a group of officials from the Ministry of Revenue that became entangled.

If Tian Ce does not hand over, he will offend three princesses and three princes. This is probably because the Ministry of Revenue will not be able to get through in the future.

But if the land book is handed over to Jingyang out of filial piety, it is also moved by the filial piety of the princes and princesses.

The beauty of adulthood may not care about the filial piety of the princes and princesses, and even if they are concerned, they may still make Princess Gaoyang and the others plead for mercy.

Besides, the queen is happy to have this little filial piety, and His Majesty doesn't think it's too scrupley.

Several officials from the Ministry of Revenue were sweating profusely and were talking.

If you don’t hand over the land book file, you may be unhappy today’s queen.

Although the court rules and regulations cannot be read casually, the queen is also a person who knows the general, but she feels a little unhappy if she doesn't say it.

After weighing the pros and cons, the Ministry of Revenue took out the land book and filed more than ten miles around Chang'an and hurriedly sent it to Jingyang.

After three days of surveying and mapping, Li Zhi and a group of students from the academy also made the design plan.

There was a sand tray in front of Li Zheng, and there were various buildings on the sand tray. The largest was Chang'an City, and the other scattered were the villages and counties around Chang'an.

Li Zhi said: "The situation of ten miles around Chang'an is here. The Ministry of Revenue sent the land book and file files over two days ago, so it was considered that this sand table was prepared."

The few green lines drawn on the sand table are the first green belts to be imagined.

Li Zhi said again: "We have estimated that it takes three thousand trees to plant the first step around Chang'an, and they cannot be too close to the city wall, otherwise it will also affect the city defense, whether it is the army or the court will not agree."

Li Zheng looked around Chang'an City and said, "What is the soil outside Chang'an City?"

Li Zhi said: "Most of the desertification is quite serious, and there is too much soil erosion."

It seems that greening outside Chang'an City is a very serious problem.

Li Zheng said: "You can plant some drought-tolerant shrubs outside Chang'an City, and then lay a layer of turf to turn the outside of Chang'an City into a grassland, which can reduce the harm of wind and sand."

Li Zhi held the booklet in his hand, which was filled with various notes. He whispered: "But even if you just plant trees around Chang'an, it will be a cure for symptoms but not the root cause."

Looking at Li Zhi's expression, Li Zheng said, "You thought of it too?"

Li Zhi said: "In fact, the biggest harm to wind and sand is from the west of Longyou. In the past few generations of life, food was the priority for everything. They looked at the forest and turned the forest into fields. Finally, the fields into deserts, which is why the current situation is here."

After a pause in his words, Li Zhi whispered: "Teacher, that's the case."

Li Zhi is actually not right.

Moreover, what Li Zhi saw was even more serious. It takes a stable era to do greening for a long time.

Greening cannot be made into land in one or two years, and may even take more than ten years.

How big will the variables have been in the past decade?

Besides, greening has continued for more than ten years, or even a hundred years later.

When people live in the present, how many people will think of the hundreds of years of their lives?

Li Zhi also said: "In addition to planting trees around Chang'an, I think it is more important to plant a huge sand protection forest in the Longyou area west of Chang'an, so that most of the wind and sand can be blocked, and the scale is even tens of thousands of trees."

Li Zheng nodded with the fan.

Li Zhi lowered his head in a loss and said, "It's not easy to have tens of thousands of trees. How much manpower and material resources are needed, and it also takes years to carry out."

He slowly raised his head and said, "Can we do this by teacher?"

Li Zheng took a sip of tea and said, "Have Your Highness the King of Jin heard the story of Yugong moving mountains?"

Li Zhi nodded and said, "I've heard of it."
