While preparing to completely solve the Japanese state, Zhu Yunwen made a major adjustment to the border towns.

Chang Shengfeng, the founding prince who stayed in the northeast for two years, was transferred back to Beijing to preside over the Governor's Mansion of the Chinese Army; After returning to Beijing to report on his work, Yi Guo, who was sitting in the northwest, went to Beijing to take up his duties to prevent the Mongol army from moving south.

After Zhu Di's rebellion was put down, Beiping was renamed Beijing, and the Beiping Political Envoy Division, the Beiping Metropolitan Division, and the Northern Parallel Metropolitan Division were changed to the Hebei Political Envoy Division, the Hebei Metropolitan Division, and the Hebei Xingdu Division.

After Ping'an arrived, Zhu Yunwen ordered him to go to Rehe to build a city and take the name Chengde, and at the same time, Hebei Xingdu Division was renamed Rehe Dusi (still under the jurisdiction of Hebei Dusi), which is likely to touch the nerves of the surrounding Mongolian tribes, so a general like Ping'an is needed.

Guo Jianfeng, the Hebei Metropolitan Division, was transferred back to Beijing to serve as the military aircraft department, and the Hebei Metropolitan Division was replaced by Zhang Lun, the former commander of the First Guards Army.

The new Rehe Metropolitan Division is Zhang Hanbei, he is the famous general under Sheng Yong - "Soap Flag Zhang" Zhang Hantian, he made military exploits when pacifying North Korea and was awarded the title of viscount, but the Ministry of Rites felt that this name was a bit too much when he was canonized, and Zhu Yunwen also felt a little uncomfortable after knowing it, so he gave it the name Zhang Hanbei.

Song Xuan, the former Suiyuan Metropolitan Division, was transferred to the Shaanxi Metropolitan Division, and Long Kai, the former commander of the Fifth Cavalry Army, took over as the Suiyuan Metropolitan Division.

Shaanxi Xingdu Division was renamed Gansu Metropolitan Division, and Zhang Fu, the former commander of the Ninth Guards Cavalry Army, was appointed as Gansu Metropolitan Division, which was still subordinate to Shaanxi Metropolitan Division.

Wu Sheng, the former Liaodong Metropolitan Division, was transferred to North Korea and served as the Korean Metropolitan Division, and the Haidong Metropolitan Division was under his command.

The Liaodong Metropolitan Division was taken over by Wang Zhong, the commander of the Third Cavalry Army, the Heilongjiang Metropolitan Division was taken over by Xiong Hai, the commander of the Eighth Guards Cavalry Army, the Jilin Metropolitan Division was held by Anpingbo Li Yuan, and the Liaodong Metropolitan Division and the Heilongjiang Metropolitan Division were all under the command of the Jilin Metropolitan Division.

Geng Xuan, Marquis of Changxing, went to the northeast to succeed Chang Sheng, and sat in Changchun, which included Liaoning, Jilin, Heilongjiang and northern Korea.

Tan Yuan, the former director of Huguang Metropolitan Division, was transferred to Yunnan and served as the Yunnan Metropolitan Division; The commander of the Second Guards Infantry Corps transferred Cao Yushu to Guangxi and served as the capital of Guangxi.

He Fu, the former Guizhou Metropolitan Division, was transferred to the General Supervision Department as a supervising squire, and Zhuang De took over as the Guizhou Metropolitan Division.

In addition, Zhu Yunwen also reorganized the intelligence department, of which the intelligence department was renamed the Military Intelligence Bureau, which was subordinate to the General Staff; The Security Department was renamed the Security Bureau and was subordinate to the Emperor; The Investigation Division I and the Second Investigation Division were renamed Investigation Bureau I and Investigation Bureau II.

Song Chengping, a loyal uncle, was dismissed from the post of director of the Security Bureau and transferred to the Huguang Metropolitan Division; Tie Wuchen, director of the Military Intelligence Bureau, was transferred to Haidong and served as the commander of Haidong......

......

In short, after this adjustment, the veterans have been transferred to the Beijing Division and held idle positions; The commanders of the Guards Army, the best of the first batch of students of martial arts, were promoted to lieutenant generals, and at the same time promoted to the rank of capital division, taking charge of the frontier military power; At the same time, a new generation of commanders of the Guards Army has also grown up one after another, and they have all been trained by the Martial Arts (now the Army University), and their cultural level and professional level have been greatly improved.

Through this readjustment, Zhu Yunwen institutionalized and standardized the five-year transfer of generals and the seven-year demobilization of soldiers, thus minimizing the possibility of generals supporting their own troops.

......

Although the conquest was very important, it was not Zhu Yunwen's first priority, and what he valued most was to open up the Northeast, which of course now includes North Korea.

Geng Xuan went to the northeast to continue to integrate the army in the northeast, but also to threaten the Mongols from the flank.

Since the retreat of Warat to the west, the situation of the Mongolian steppe has changed greatly, and now Mongolia has been divided into two parts, east and west of Warat, east of the Golden Family, and the leader of the Xiangyuan Khan Di Baonu.

Shortly after Waratsi's return, the great chieftain Ugqi fell ill and died. Since the unification of the four parts of Warat, Ugqi's health has been not good, after the return of the Dibaonu to the grassland, Ugqi felt that he would die soon, so he gave up the idea of competing with the Dibaonu and led the troops to return to the west.

Eseku, who succeeded to the throne as the great chief, adopted the suggestion of the national teacher Wang Xing, and in the eighth year of Jianwen, he sent an envoy to the Ming Dynasty to request canonization and mutual markets.

After considering all aspects, Zhu Yunwen sent an envoy to canonize the Eseku as "King Gongrui", and the location of the mutual market was set in Hami, and he was not allowed to enter Jiayuguan.

At the same time, Zhu Yunwen also adjusted the policy of tea and horse exchange, in addition to the tea and horse division, merchants were allowed to carry tea to Hami to trade horses, but heavy taxes were levied on tea leaves and horses entering the customs to subsidize border defense.

Eseku, who received the edict, was very grateful and was willing to conquer Eastern Mongolia, but Zhu Yunwen refused. On the contrary, Zhu Yunwen, in the name of disrespectful to the Ming envoys, ordered him to conquer the Timurid Khanate, and the same conquest order was issued to the Eastern Chagatai Khanate.

The Timurid Khanate was also undergoing some changes, and although Pil Khan defeated his younger brother Khalil, he could do nothing about his uncle Shaharu in Herat, and the huge Timurid Khanate was at risk of splitting.

For this reason, Peel did not hesitate to send people to the Ming Dynasty to claim his courtesy, hoping to gain the support of the Ming State, but the attitude of the Ming State was very ambiguous and there was no clear attitude.

In March of the ninth year of Jianwen, Ping An left the northwest and was transferred to Hebei.

In April, the Eastern Chagatai Khanate was the first to start a war with the Timurid Khanate under the banner of restoring the old capital of Samarkand; At the end of May, the Warat cavalry bypassed the Tien Shan Mountains and launched an attack on the Timurid Khanate from the north.

Faced with a grim situation, Peel accepted his subordinates' advice, made peace with Shahru, transferred back the forces guarding against Shahru, and engaged in a fierce battle with the Eastern Chagatai Khanate and the Warat army, and the battle fell into a stalemate for a while.

......

The land protectors in the east are a different story.

After the withdrawal of Warasi, the Dibaonu was very energetic and trembling at the beginning. On the one hand, he sent envoys to the Ming Dynasty to ask for mutual markets, and at the same time restrained the Mongol cavalry from approaching the border passes of the Ming Dynasty; On the other hand, they sent people to inquire about the movements of Warat, lest Warat make a comeback.

In order to conquer the Wa Kingdom, Zhu Yunwen agreed to his request for mutual markets, and at the same time tried to canonize him as the "King of Shunyi", but the land protectors wanted to accept it, but most of the Mongolian tribes were resolutely opposed, so they had to give up.

When the news of Ugqi's death reached eastern Mongolia, Dibaonu was so excited that despite the opposition of his vassals, he ordered a three-day celebration.

Soon after, Dibaonu received a letter from Samur stating that Eseku had been canonized by the Ming court and wanted to conquer Mongolia and serve the court.

Faced with the threat of the Eseku, the land protectors and their vassals looked at each other and had nothing to do.

In the end, Dibaonu accepted Zhu Yunwen's canonization and accepted the title of "King of Shunyi", but at the same time, it caused the centrifugation of the Eastern Mongolian tribes. Certain tribes moved westward, seeking the protection of Warat; Certain tribes went north in search of new pastures; At the same time, some tribes went south and accepted the jurisdiction of the Ming Dynasty.

In view of this situation, Zhu Yunwen transferred Ping'an to Hebei to preside over the establishment of the Rehe Capital Division, and of course, leaving the northwest safely, there was another advantage, that is, so that the Eastern Chagatai Khanate and Warat could attack the Timurid Khanate with confidence.

If you want to build Tohoku, railways are indispensable.

The railways from Dalian to Shenyang and Pukou to Kaifeng were in operation for less than two months, and everyone realized the advantages of the railways, and the speed and efficiency of material allocation were completely incomparable.

For this reason, Zhu Yunwen was as good as a stream, and set up the Ministry of Railways, and the first secretary was Yan Zhenzhi, the former secretary of the Ministry of Works.

According to the suggestions of officials at all levels in Northeast China and on-the-spot surveys, on June 15 of the ninth year of Jianwen, Yan Zhenzhi took out the planning map of the Northeast Railway.

According to his plan, after the railway from Dalian to Shenyang is completed, it will continue to extend northward, through Siping and Changchun, and after arriving in Changchun, it will be divided into three lines, one line to the northwest, through Songyuan, to Baicheng, from which you can launch an attack on Mobei Mongolia; The first line went northeast and arrived at Harbin, the political envoy of Heilongjiang; The line goes due east to the sea, where sea cucumbers are produced, which the locals call "Vladivostok".

When he heard Yan Zhen mention Vladivostok, Zhu Yunwen almost jumped up, this is the eternal dream of later generations of Chinese people and Northeast people, the Northeast is vast, the land is fertile, and the products are abundant, but there is no real outlet to the sea, only Dalian located in the Liaodong Peninsula can barely be counted as one, but it is blocked by the Korean Peninsula and the Japanese archipelago, and cannot face the ocean.

No one noticed Zhu Yunwen's strange appearance, and all the civil ministers and generals were immersed in excitement. In Wenchen's eyes, with these railways, the three political envoys will really be established, and the Ming Dynasty will be able to firmly control these territories; In the eyes of the generals, these railways were all routes for transporting troops, which could effectively control local rebellions......

In addition to the excitement, Hubu Shangshu Yuxin raised a question, that is, the Shenyang-Dalian Railway extends to the north, so why doesn't the Pukou to Kaifeng Railway extend to the north?

Oh, yes? Why?

Yan Zhenzhi was a little frustrated in the face of everyone's doubts, and he said a problem that everyone did not expect, that is, it is currently impossible to build a bridge over the Yellow River that can be passed by rail.
