"Sun Chuanting was appointed to govern Hetao and Ningxia, to control the Northern Army Governor's Office, and to prepare for the removal of the set."

On the thirteenth day of the first lunar month of the fourth year of Tianqi, when the Tianxiawei Office was innovating, Sun Chuanting also received his new official position in the Xi'an Trilateral Governor's Office.

The Hetao strategy and control the Northern Army Governor's Office, obviously, this will be the afterglow of civil servants' restraint of military generals.

"Sun Chuanting, receive the order..."

Sun Chuanting stretched out his hands to take the imperial edict, looking at the will in the imperial edict, and felt full of enthusiasm.

Fuhetao...

The three simple words represent the Ming Dynasty's determination to completely recapture Hetao.

Once Hetao is recovered, Ningxia, Yansui, Guyuan, and the entire Guanzhong Plain will be far away from the iron hoofs of the Beilu, and can be engaged in production with peace of mind.

Thinking of this, Sun Chuanting also walked back and forth in the study in the mansion for several steps, and then asked the Jinyiwei who was delivering the letter:

"Where is Governor Manchu now?"

"Returning to the preaching, the Manchu Governor just brought the three guards of the Daning to Yanshan yesterday. His Highness is preparing to let the governor lead the three guards of the Daning to Shaanxi to start the abolition of the Shaanxi Governor's Office and reorganize the four northwest towns."

The Qianhu, Xi'an, who delivered the letter, reported and said:

"Your Highness also explained this decree. Although it is a reconciliation, it is not in a hurry. All the strategy needs to do is cooperate with the Mandu Governor to rectify Shaanxi, Hexi military affairs and military farming."

"After the autumn harvest next year, if the materials are sufficient, wait for Your Highness's military order to launch a sweep immediately. If it is insufficient, the Imperial Horse Supervisor will reissue it."

Qianhu General Zhu Youjian's words were brought to Sun Chuanting intact. When Sun Chuanting heard this, he also said slightly:

"At present, the first thing to be affected is Yansui, General Li of Guyuan and the other two places did not respond much."

"Please send someone to tell Your Highness that the 30,000 soldiers in the hands of the three guards of the Daning, may be a little short of the 30,000 soldiers in the hands of the following officials. Please transfer the soldiers of the three guards to be fully confident."

"The official remembers it." Qianhu responded, and saw that Sun Chuanting had nothing to say, so he took the initiative to speak:

"The Master, Your Highness also sent an official to ask about the Master. Do you dare to ask if the land in Hexi can be settled?"

Whether Hexi can be reclaimed means whether the Ming Dynasty can send troops to the Western Regions. Zhu Youjian is very concerned about this, and Sun Chuanting also knows it.

Therefore, when he arrived in Shaanxi, he asked the Military Reform Warehouse to visit Hexi. However, the situation in Hexi was complicated and it was difficult to explain clearly for a while. Sun Chuanting could only speak:

"I will tell His Highness the situation in the Hexi land in the future."

"Since that's the case, then the official retreated." After hearing what Sun Chuanting said, Qianhu stepped out of the three-sided governor's mansion after bowing.

But after he withdrew, Sun Chuanting walked to the desk, picked up a document and started reading it.

This is the situation of innovation in Shaanxi garrison. Sun Chuanting's 30,000 soldiers did not contact the four towns in the northwest as soon as possible, but instead carried out innovation in the southern Shaanxi area.

Shaanxi and Shaanxi Xingdusi have a total of 28 guards, involving nearly 160,000 households, millions of people, and nearly 8 million mu of land.

This is still a garrison, and there are tens of millions of acres of herd fields in Taipu Temple.

If the more than 8 million acres of land can be recovered and distributed, it can support at least 6 million people in three acres.

"If Shaanxi suffers from suffering, if it can support millions of families with these acres, it will be of great merit..."

After sighing, Sun Chuanting put down the documents, sorted out the table, spread the letter paper, and began to lift the pen to write.

He first focused on the description from the military geography of Hexi, because for the Ming Dynasty, guarding Hexi was not an easy task.

First of all, the geographical location of Hexi is very unfavorable to the Ming Dynasty's defense. The north of Hexi is the Ordos tribe in Ningxia, which has been hostile to the Ming Dynasty for a long time, and is also the focus of the Ming Dynasty's defense.

The western part of Hexi is the two remaining parts of the Eastern Chagatai Khanate, namely the two major Khanates, Yarkand and Turpan, and the southwest part of Hexi is the Dogandus.

Although the religious leaders of the snow-capped areas in the Ming Dynasty had already surrendered to the Ming Dynasty, this was not a region directly under the Ming Dynasty. In addition, the late Ming Dynasty's weakening control over local areas, so the Qinghai area in the south gathered a large number of western, northern and northern deserts.

The Mongolian tribes in the south.

The complexity of this place is much more complex than Zhu Youjian imagined.

Therefore, Hexi in the Ming Dynasty can be said to be uneven in the north, west and south directions, and the natural environment in Hexi is also very unfavorable to the Ming Dynasty's defense.

Most areas of Hexi are plateau mountainous areas, and precipitation is very sparse, so most areas of Hexi are not conducive to agricultural production.

After surveying some people sent by Sun Chuanting, they reported to him that the land of Hexi could only rely on the narrow corridors of the Qilian Mountains and the Longyou area.

Therefore, not only now, but even in the future, the troops deployed by the Ming Dynasty in Hexi must be deployed in the Hexi Corridor area in the form of a long snake formation.

This formation is very likely to be cut off by the mobile and flexible cavalry during wartime, causing the entire Hexi defense line to collapse.

This is just a military perspective. If we go from the economy and population, it is even more unoptimistic.

Since the late Tang Dynasty, most areas of Hexi have been ruled by Tubo and Dangxiang. Before large-scale population migration began in the Central Plains, these young people occupied Hexi.

After years of ethnic minority rule, Hexi has a different culture from the Central Plains.

These cultures have led to the fact that the large number of local people in Hexi are actually more likely to be outside the pass, and they are also quite wary of the Ming Dynasty. The Han people in Hexi also discriminate against the Han people east of Longshan.

If the people were to be moved to Hexi and cultivated a large amount of land, Sun Chuanting's suggestion was to use the power of the court to migrate a million people, consume tens of millions of stones of food and fodder, and take three years to cultivate millions of paddy fields.

But if you transport grain by land, from Shandong, Nanzhili, Henan to Hexi, 30 million stones may only be transported to 8 million stones...

"The situation in Hexi is so complicated, it is beyond my expectations."

When Sun Chuantingxin was sent to Yanshan Camp, Zhu Youjian only read the military annotations and realized the difficulty of the Ming Dynasty to govern Hexi.

If in Sun Chuanting's view, the dilemma in Hexi is only to solve local conflicts and solve the problems of transporting grain and migrating the people, then in Zhu Youjian's view, these are actually not problems.

Local conflicts can be deterred by the army. It does not require violent means to migrate people during severe droughts. Tracked grain can also be transported by horse-drawn carriages. Some labor force is needed during severe droughts.

These three points are not a problem in Zhu Youjian's opinion. The only difficulty he had after reading this letter was Sun Chuanting's description of the climate of the Hexi Corridor.

Although Zhu Youjian didn't remember the 400 mm precipitation line and 200 mm precipitation line in later generations, he also knew that the former could reach the Lanzhou area in Hexi, and the latter could even reach the vicinity of Jiayuguan.

However, in Sun Chuanting's description, this precipitation line moved eastward by at least 200 kilometers.

Because there was a saying in his letter, "There was a few dozen rains in Jiayuguan a year at the beginning of the country, and then it decreased gradually. Only Zhengde, but during the Jiajing period, it increased slightly, and then it was the same as before."

In Sun Chuanting's words, if Zhu Youjian remembered correctly between Zhengde and Jiajing period, it was the only small warmth period in the middle and late Ming dynasties, but it was far inferior to later generations.

The temperature in the whole world is dropping sharply, and the Ming Dynasty is even more serious than that of countries around the world due to various climate problems such as geomonsoons.

If Zhu Youjian remembers correctly, the temperature in the fifteen provinces of the two capitals was three degrees lower than that in later generations.

The deviation of two or three degrees does not seem very cold, but the average temperature is a very important data, and one or two degrees of deviations are a huge impact.

These two or three degrees of deviations represent the southward movement of the rainfall zone, the sharp drop in the north, and insufficient snow in winter, resulting in winter wheat being frozen to death without snow covering and being unable to survive the winter.

The dry climate in summer has led to a sharp increase in the success rate of locust egg hatching, and the locust plague is raging.

Therefore, if the rainfall belt in Hexi moves hundreds of kilometers eastward, it means that Hexi during this period will definitely not be able to reclaim 40 million acres of paddy fields like later generations.

The migration of hundreds of kilometers eastward may mean that tens of millions of acres of land are not suitable for cultivation.

Thinking of this, Zhu Youjian's face was a little unfavorable. After all, the gap between 40 million mu and 30 million mu represents that it can support 30,000 cavalry and 150,000 civilians to go out for six months and run around the Western Regions by 1,020.

Nearly tens of millions of stones of grain per million.

Even if this food is not used to support the expedition, it is enough to feed millions of people in the local area.

"We must figure out how many people there are in Hexi..."

Thinking of this, Zhu Youjian in the study of the Royal Horse Supervision of Yanshan Daying put down Sun Chuanting's handwritten letter and greeted the Jinyiwei at the door:

"It's said that Mangui is here!"

"Yes..." Hearing Zhu Youjian's words, the Jinyiwei at the door immediately sent someone to notify Man Gui who was still resting in Yanshan Camp.

A quarter of an hour later, Man Gui came to the backyard of the Imperial Horse Supervisor, then turned over and dismounted, walked into the yard wearing a round neck robe. Before he could reach the door, he heard Zhu Youjian calling him in.

"Your Highness..."

The first thing Man Gui did when he entered the door was to salute, while Zhu Youjian said to him through the screen:

"Come in the study and sit down, there are some things that need to be explained to you."

"The last general will take the order." Man Gui walked down and walked into the study, then sat on the already-placed chair.

Since defeating Bayeux, Man Gui has not returned to Northern Zhili for two and a half years. Although the last time he met was a few months ago, it is not difficult to see his appearance that he was very tired during this period.

"You have been back to Yanshan Camp for four days. I heard from the commander of the three guards of Daning that you did not have a good rest some time ago, so I did not summon you."

"Now it seems that you should have a rest for a while, otherwise you will be tired and down halfway through before you even arrived in Shaanxi."

Zhu Youjian was teasing with concern, and Man Gui smiled and said:

"After all, we have to hand over the defense of the three guards of Daning. Now that the three guards are transferred, there are only 34th battalions in Liaodong. Zhejiang and Shandong each have three battalions that cannot be mobilized. The Eastern Army Governor's Office has only 70,000 infantry in Liaodong, 30,000 in the United States.

The iron cavalry is here.”

"Why isn't it enough?" Zhu Youjian was not worried about Liaodong. Not to mention defending Liaodong, the 34th battalion was enough to attack Wula City, the current temporary capital of Jianlu.

"Of course it's enough." Man Gui smiled heartily and talked about the military achievements of the Eastern Army Governor's Office:

"The Iron Cavalry of the Tenth Battalions of Liaodong, since the end of the Liao Dynasty, has raided Jianlu in five months, and harvested more than 1,200 true captives and more than 2,700 fake captives."

"Faced with the attack of the cavalry of our Eastern Army Governor's Office, Jianlu could only continue to shrink northward. If it weren't for the refugees and the settlement in Liaodong that were not over yet, I'm afraid that as long as your highness allocated money and grain, he would be able to plow the courtyard and sweep the cave again with a command.

.”

The situation in Liaodong was very good. Nurhaci's death of nearly 30,000 horse infantry in the battle to restore Liaoning made the Jin army's mobility almost halved.

Even though the cavalry of the ten battalions of Liaodong are all one man and one horse, after cooperating with the slow horse, they can still go out more than 300 miles to harass Jianlu.
To be continued...
