Of course, Gao Zhitai is not a benevolent and righteous person, and if he does not talk about the three Xuanfu Divisions in southern Xinjiang, such as An, Hue, and Quang Nam, it is obvious that he cannot talk about benevolence and righteousness if he says that the Thang Long and Hai Duong Xuanfu Divisions he took away in North Annan.

That area is the most elite part of the Red River Delta, equivalent to the two municipalities of Hanoi and Haiphong in later Vietnam, plus the four provinces of Hai Duong, Taiping, Hung Yen and Bac Ninh, roughly speaking, accounting for 90 percent of the Red River Delta.

In terms of the weights and measures of later generations, this is a fertile soil of about 7,000 square kilometers, with fertile land, abundant water and abundant sunshine, and is the natural choice for the development of agriculture, especially the cultivation of rice, and there are few areas in the world that can match it in this regard.

Then with a stroke of the pen, I want this land......

You must know that the entire Honghe Plain is about 20,000 square kilometers, and he is going to go to one-third of it at once, which is still the most essential part, how can he be embarrassed to say benevolence and righteousness?

However, even so, the Cen and Huang families can still accept it, because if they don't have high pragmatism, they won't be able to get anything.

However, Gao Shipra's desire for the grain-producing area of the Red River Delta is not mainly considered from the perspective of economic interests, but from a political point of view: mastering the grain can control the population, so mastering the grain-producing area is the only way to "immigrate for blood", and at the same time, it will also lay a material foundation for the continued expansion of the Han family in the future.

Daming is about to enter the Xiaoice River period, he has to transport grain back to save the emergency, how much grain to pull out!

Therefore, the Red River Delta must be mastered, otherwise things will not be easy to do in the future. And the Cen and Huang families carved up the remaining more than 10,000 square kilometers of the Red River Plain, which was already a huge surprise for them.

In the past, the Huang family still had a narrow and cramped Mingjiang Plain, which could grow some grain, but the Cen family was almost all mountain fields, and there were not a few acres of good land at all.

In later generations, Vietnam's rice yield per mu was much lower than that of China, but its total grain output was equivalent to the sum of Hunan, Hubei, China's two major grain producing areas, close to 50 million tons. What is the concept of 50 million tons of land produced in Vietnam alone?

This means that in the current period when the yield per mu of Daming and Annan has not opened a big gap, the grain output of a Honghe Plain may be close to that of the entire Huguang.

The lake is wide and ripe, and the world is full.

The Cen and Huang families each got one-third of Huguang, which is already crazy!

Of course, it doesn't mean that these fertile fields all belong to the Gao Pragmatic and Cen Huang families, after all, those people in the Mo Dynasty are not dead...... They also have to slowly find excuses to fight local tyrants and divide the land.

The division of the Red River Plain is better to say, starting from Yi'an, and the areas further south were packed and taken away by Gao Shishi, which is not to mention benevolence.

Although these areas are still wild places even in the eyes of the people of Annan, Gao is aware of their development prospects. The region's agriculture is not as good as that of the Red River Plain and the Mekong Plain in its high-profile vision, but it is also self-sufficient, and its real strength lies in minerals.

Originally, with a high pragmatic geographical level, he also knew that Ha Tinh had a high-grade large iron mine, and basically didn't know anything else, but after he started to fight the idea of Annam, he sent someone to Liu Xin to ask her about the distribution of mineral resources in Vietnam in later generations.

Liu Xin went to Tengchong, Yunnan to meet her eldest brother Liu Wei after contacting the supply of notoginseng in Sichuan, which was very close to Guangxi, and the reply was naturally fast.

Liu Xin not only marked some important mining areas and main minerals that she remembered, but also carefully drew various metallogenic belts - Gao Shishi didn't particularly understand this thing, but he generally knew what it meant.

The three Xuanfu of Nghe An, Hue, and Quang Nam that he won were clearly marked in the map given to him by Liu Xin as belonging to the "Changshan Fault-fold Metallogenic Belt" and the "East Indochinese Fault-Block Metallogenic Area", removing those manganese ore, lead-zinc ore, bauxite and other things that Gao Pragmatic could not do with anything, and the most critical and immediately usable minerals in these two places were iron ore, gold ore, and copper ore.

There is still coal here, but according to Liu Xin, it is not convenient to dig coal here, because it is very hidden, and it is not easy to do it with the technology of this era, so it is best to go to Quang Ninh Province to dig coal - this is what Liu Xin said according to the political planning of later generations, in fact, it corresponds to the Anbang Xuanfu Division that has been assigned to Huang Zhiting.

The coal reserves of Anbang Xuanfu Division are very large, and they are high-quality mines, and this place is close to the sea, and the sea transportation is very convenient. The only trouble is probably the pirates near Ha Long Bay, which can only be eliminated after the battle - but theoretically, the pirates probably don't rob coal carriers, right? Annan is not cold, what is the use of them grabbing coal, cooking?

As for the northwest region that Cen Ling was assigned to, in fact, the mineral resources are also very rich - there are many mountains over there, copper and iron, but because the Hejing iron ore is good enough, Gao Pragmatic does not need Cen Ling to dig iron ore, he only needs to dig copper ore on the land of Xinghua and Xuanguang Xuanfu Division, after all, copper ore is a good thing in this era, whether it is to cast money or cast cannons, there is no shortage of copper mines, but there is a shortage of copper in the Ming Dynasty.

Gao's pragmatic plan was that the copper mines in the areas under his control would be developed and utilized by himself, while the copper mines on Cen Ling's side would be shipped back to Daming along the Red River. As for what Daming used to do, whether to cast money or cannons, Gao Pragmatic didn't care.

In the area that Huang Zhiting was assigned, there was still a small iron mine in Langshan, which could also be built there, but also because Gao Shicheng didn't need it, the iron ore there could also be transported back to Daming.

Cen Ling's copper and Huang Zhiting's iron, these are all gifts from Gao Pragmatic Plan to Zhu Yijun for free, saying that it is free, but in fact, it is spending money to buy peace, and there is not much difference between follow-up tribute, but Zhu Yijun is not needed to give it back.

What Zhu Yijun wants to do is very simple - just give a name.

This approach is very pragmatic, and this is how he got the soap monopoly from Emperor Longqing back then. It's just that the situation has changed slightly, and it is Cen Ling who took copper and Huang Zhiting latte in exchange for the recognition and approval of Zhu Yijun, His Majesty the Ming Emperor, for their "moving to Annan".

Speaking of which, in terms of cost-effectiveness, Zhu Yijun is the most cost-effective, nodding and writing a "can", there will be a large amount of income in the account, which can't be more enjoyable.
