Li Zicheng has nothing to do these days, and Li Zicheng is almost always nesting in the girls' school during the day, and he must seize all the time to make up for the days of his previous leave, and strive to let these students graduate early, so as to teach more students.

In order to deal with Cao Wenzhao's extermination of thieves in Shaanxi, Guanting Ferry not only had heavy troops stationed with horses and water, but also transferred more than 300 soldiers from the Song Wen Department to prevent thieves and displaced people from crossing the Yellow River in large numbers and pouring into Xining.

In the afternoon of this day, Li Zicheng came to the study to go around, and by the way, he checked the messages from each other, and Wang Anping's ranger finally sent a message from Shaanxi.

According to the information, the thieves in Shaanxi have been dispersed by Cao Wenzhao, and the leader of the thieves has fallen apart either dead or captured, and Li Zicheng breathed a sigh of relief.

This is strikingly consistent with the history of later generations, neither thieves nor homeless people look down on a frontier like Xining, or even if they come to Xining, they have no sense of security in the multi-ethnic melting pot.

There are three main directions for the escape of the displaced people: the southwest direction, through the Shu Road into Sichuan; In the southeast direction, it crosses the Yellow River and enters Luoyang, Henan Province along the ancient road; There is also a place that directly crosses the Yellow River to the east and enters Shanxi.

As long as an army is stationed in the imperial court, with the fighting power of thieves and the power of unrestrained chickens, it is impossible to pass on a large scale, or in other words, the thieves and homeless people who fled along these two roads were basically wiped out by the army of the imperial court.

Zhang Xianzhong later entered Sichuan, and he was called king in Xichuan, that is, he took the initiative to enter Sichuan, and after surrendering to the imperial court, he was protected by the imperial court, and had enough time to cross the Shu Road.

At present, most of the thieves and homeless people in Shaanxi, just as Wang Anping said, have fled to Shanxi, which is across the river, except for those who have been exterminated.

Whether the thieves fled to Shanxi, Henan, or Xichuan, as long as they were far away from Xining, they had no direct relationship with Xining, and even if Li Zicheng wanted to rescue them, it was far from quenching their thirst.

Li Zicheng picked up the marching map, now it is Sanchuan Mansion, that is, the original area of Nianbosuo, which has concentrated two divisions of Ma Youshui and Song Wen, more than 800 soldiers, since there is no follow-up to the thieves, they can't be idle, it is better to take the opportunity from the south to the north and take the Gulangsuo first.

Judging from the marching map, Gulangsuo is close to the side wall, and its location is relatively independent, between Zhuanglangwei and Liangzhouwei.

The area of the Gulang Institute is not large, and there is a watershed between Zhuang Langwei, which should be subordinate to Liangzhou Wei, but now it is an independent place, I don't know what the reason is, maybe when the Wei was designed, between Zhuang Langwei and Liangzhou Wei, there is an extra vacant land, and it can not be idle, and the imperial court set up the Gulang Institute here to protect this section of the side wall.

This is just a feeling, Li Zicheng doesn't know the true situation of Gulang, the last time Wang Anping sent a message from Gulang, his mind was not in Gulang, he just browsed it at random, and didn't deliberately remember it in his mind, he seemed to remember that Wang Anping didn't use carrier pigeons, but specially ordered the rangers to send back the message.

He rummaged through the documents, and sure enough, he found the message, which turned out to be a military defense map of the Gulang Institute, which was marked in great detail, because the capacity was too large, so it was impossible to use carrier pigeons, Wang Anping probably because the Gulang Institute was adjacent to Zhuang Langwei, which was already subordinate to Xining, so he put a lot of effort into the Gulang Institute

。

Completely contrary to Li Zicheng's assumption, Gulang was a rather important guardhouse, named after a river called "Gulang" in the territory, and to Li Zicheng's surprise, this river, which nourished the Gulang army and civilians, actually broke out of the side wall and eventually flowed to the desert to the east.

Although it is a desert, but outside the border wall, is the world of the Mongols, and the Gulang River Valley is the passage of the Mongol invasion, although the water volume of the Gulang River is far inferior to the Shiyang River and the Qiulai River in its northwest, and the aquatic grass along the coast is not vigorous enough, however, if the Mongols suffer from natural disasters or something, once they are extremely hungry, they will also invade along the Gulang River Valley, so the main military purpose of the Gulang River is to protect the gap in the border wall.

There are not many forts and posts in the territory of Gulang, there are only a few such as Songlin Fort, Shixia Pass, Surabaya Tunbao, etc., but these forts are all east of the Gulang River, between the Gulang River and the side wall, in addition to the arch guarding the side wall, the main thing is to guard the passage of the Gulang River Valley, especially the Shixia Pass, it is said that the first to build the pass was the general Huo Qubing of the Han Dynasty.

Commensurate with the extremely important position of the Gulang Institute, the actual number of soldiers in the current Gulang Institute has reached 500, which is comparable to a "guard" soldier in the situation of the great escape of the soldiers of the guard.

The opportunity is in front of you, but there are too many soldiers in Gulang, the land is small, and the soldiers are relatively concentrated, so it is too difficult to take Gulangsuo and all the forts without blood.

Li Zicheng originally wanted to command in person, but after thinking about it, he gave up, he wanted to be in charge of the overall situation, if it wasn't a critical moment, it would be better to leave Xining less, besides, he also had to teach the students of the girls' school, now it may be easier, once he is busy, he may not be able to teach for a long time.

The most important thing is that in order to let hundreds of officials learn to fight, they must be given the opportunity to train on the battlefield, if they are like Zhuge Liang, they must bow down to themselves, and in the end it must be the talent zero, "There is no general in Hanzhong, Liao Hua is the vanguard", which is not only a tragedy of Shu, but also a tragedy of Zhuge Liang's personal character.

Now there are only 800 soldiers in the left side of Sanchuan Mansion, and if they want to concentrate their superior forces and take Gulangsuo in one fell swoop, it seems that Ma Youshui and Song Wen will have to join forces, but both of them are officials of 100 households, who will be the main official to lead this battle?

Li Zicheng thought for a moment and decided to hand it over to Song Wen.

Although Song Wen is not a descendant, but Song Wen is old and has more combat experience, although Ma Youshui is from the chief flag officer of the pro-soldiers, he can be regarded as a descendant, but he is too young and has little battlefield experience, the last time he conquered the Salars, he almost had a problem, and almost lost his life, in a word, although he has tiger spirit and blood, but he is still too tender.

The last time Song Wen, as Liu Yunshui's auxiliary officer, assisted Liu Yunshui in taking the Nian Bo Institute, and treated him fairly, he should be given the opportunity to lead the troops into battle, and Ma Youshui had already attacked Zhuang Langwei's various forts relatively independently.

Li Zicheng packed up the marching map, and immediately wrote a long letter to Song Wen, together with the military defense map of Gulangsuo, and prepared the herald to send it to Sanchuan Mansion, in the letter, Li Zicheng repeatedly warned Song Wen that he must make adequate preparations, strive for the bloodless blade, block the message, and do nothing wrong to the people.

Before occupying the entire Shaanxi Xingdu Division, Li Zicheng didn't want to turn his face with the imperial court, or rather, he just wanted to hide under the wings of Chaotian, make a fortune in a muffled voice, and accumulate his strength little by little.

At this time, spring ploughing has long been over, and small-scale battles, as long as they are not tug-of-wars, will not affect agriculture

Production and harvest, the future Gulang Station, can also feed a certain number of soldiers.

In addition, Li Zicheng also sent a short message to Ma Youshui, instructing him to settle the affairs of Sanchuan Mansion first, especially the dozens of Salar people who were used as cultivators, and the other thing is to fully assist Song Wen and quickly take down Gulangsuo, everything, mainly Song Wen.

Handed over the two letters to the herald and asked him to send them to Sanchuan Mansion as soon as possible, it was almost too late, Li Zicheng hurriedly went to the girls' school and taught half an afternoon's class.

Seven days later, Li Zicheng had just returned from the girls' school, and he had already received the message that Song Wen had taken the Nian Bo Institute, because it was a flying pigeon to pass the book, the amount of information was not large, and the details would be specially delivered by the heralds.

Li Zicheng came to the study alone, unfolded the march map, and saw the entire Hexi Corridor.

The Shaanxi Xingdu Division, which was attached to the Shaanxi Chengxuan Political Envoy Division, was almost the later Gansu Province, which increased Xiningwei and reduced the Longyou and Longdong Plateaus.

Li Zicheng has occupied the guard station near Xining, and now the Shaanxi Xingdu Division is almost only left with the relatively closed Hexi Corridor.

According to the trend of Qilian Mountain, the whole Hexi Corridor is roughly in the northwest-southeast direction, except for the two prominent parts of Shiyang River and Xulai River, it is basically rectangular, the west is Qilian Mountain, the east is the side wall, the north is Jiayuguan, and the south is the watershed of the branch of Qilian Mountain, which is called Wusheling in later generations.

When the Xining army occupied Zhuanglangwei, it was equivalent to breaking through the watershed in the south, and it already had a geographical advantage, and Song Wen entered the Gulangsuo, which was equivalent to gaining a certain depth in the north of the watershed, and had penetrated deep into the southern part of the Hexi Corridor.

The current Shaanxi Xingdu Division is quite embarrassing, the west, east, and north are the Qilian Mountains and the side wall respectively, and the only landshed in the south that has a land connection with the interior of the Ming Dynasty is in the hands of the Xining Army.

Catch a turtle in an urn.

Such a thought flashed in Li Zicheng's heart, but he could only think about it, but it was very difficult to realize.

Although the Hexi Corridor is closed, there are mountains and rivers inside, which meets the conditions of the military cantonment and can support a large number of soldiers.

At least so far, there are Liangzhou Wei, Shandanwei, Yongchang Wei, Ganzhou Wei, Suzhou Wei, Zhenfanwei, and two guards of thousands of households: Zhenyi Office, Gaotai Office, especially Ganzhou, which has five guards: Ganzhou Qianwei, Ganzhou Guard, Ganzhou Zhongwei, Ganzhou Left Guard, Ganzhou Right Guard, according to the establishment of 5,600 soldiers per guard in the early Ming Dynasty, there are 28,000 soldiers in Ganzhou Wei alone, which is really a terrifying number.

However, judging from the situation of Xiningwei, Zhuang Langwei, Nian Bo, and Gulang, by the end of the Ming Dynasty, it was impossible to still be full, and fifty percent of the soldiers would be the top of the sky.

Even so, the current Hexi Corridor is still much larger than the Xining Army that Li Zicheng now controls, and it will not be easy for Li Zicheng to fight their idea.

What's more, in the northwest of the triangle city, there are Mongolian cavalry harassing from time to time, and east of the Yellow River, there is also Shaanxi Province of the Ming Dynasty.

If you want to think about the entire Hexi Corridor, it is still too far away, what he is concerned about now is that the Gulang Institute now belongs to Xining, according to the convention, Gulang County will be established, and the county seat is the original Gulang Institute, which is located on the west bank of the Gulang River, and there should be enough fresh water, as long as it can produce food.
