After the Beiping Army outwitted Taiyuan City, Zeng Zhilin, Wang Feng, Muttel and others did not stop there. The three of them joined Yang Xin, who had taken Yang Ye back to the city after getting the news of the destruction of Taiyuan City, and immediately reported to Beiping City about the capture of Taiyuan, and immediately according to the pre-formulated haodejihua, Yang Xin and Zeng Zhilin stayed in Taiyuan, and Wang Feng and Mutel each led a group of men and horses to set off on the north and south roads to recover the prefectures and counties of the Northern Han Dynasty. Among them, Wang Feng led all the way to the north to attack the four prefectures of Xin, Dai, Lan and Xian, and Mutel led all the way to the south to sweep the four prefectures of Long, Qin, Fen and Shi.

Because Taiyuan has been lost, the emperor Liu Jun was also captured by the Beiping army, Liu Jun's adopted son Liu Jien and Liu Jiyuan died in the battle for Xuandemen, and the adopted son Liu Jiye (Yang Ye) received his adoptive father's will to surrender, and also officially surrendered to the Beiping army. Therefore, in the face of the surging Beiping army, the other states and counties of the Northern Han Dynasty basically surrendered immediately, and no city or man dared to confront the Beiping army. This made it only take half a month for the Beiping army to go south to attack the Han army from the 15th day of the eighth month of the lunar calendar to the beginning of September, and completely brought the land of the eight prefectures of the Northern Han Dynasty under its control, and successfully completed the established Jihua of expanding its Shili range to the southwest.

Of course, the occupation of Taiyuan City and the acceptance of the surrender and surrender of other prefectures and counties were only the first steps in the annexation of the Northern Han. Next, Yang Xin, Zeng Zhilin, Wang Feng, Muttel and others also had to cooperate with Li Junwu, Zhang Weixin, Xu Shaoan, Zhou Lei, Yu Wende, Liu Wendong and other brothers who had already arrived from Beiping City, according to the model when they received the Sixteen Prefectures of Youyun, in the shortest possible time, to integrate and reorganize the Northern Han Dynasty, the capital of the eight prefectures, so that they could integrate into the Beiping Army as soon as possible and truly become a part of the Beiping Army.

To this end, the committee decided to establish a temporary detention center in Taiyuan composed of Li Junwu, Zhang Weixin, and Xu Shaoan, which was responsible for unified command, deployment, and coordination in the process of integrating and reorganizing the two prefectures of Yanmen and Taiyuan. According to the geographical location and topographical trend of each prefecture and county, the eight prefectures under the jurisdiction of the former Northern Han Dynasty were divided into two prefectures. Among them, the four prefectures of Dai, Xin, Lan and Xian were merged into Yanmen Mansion, and the seat of governance was in Xin County (the original Northern Han Xinzhou was merged into the original Taiyuan Prefecture, Longzhou, Shizhou, Fenzhou and Qinzhou into the new Taiyuan Prefecture, and the seat of governance was in Taiyuan City. Zhong Shiwen, the former governor of Lingxian Mansion, was relocated to the prefect of Yanmen Mansion, Xin Feiyu, the former deputy chief soldier of Beiping Mansion and the garrison of Juyongguan, was relocated to the chief officer of Yanmen Mansion, and Yang Ye was appointed as the deputy chief soldier of Yanmen Mansion; Yan Chongli, the former governor of Datong Prefecture, was reappointed as the prefect of Taiyuan Prefecture, and Wang Feng, the former deputy chief soldier of Lulong Mansion and garrison of Shanhaiguan, was relocated to the chief military officer of Taiyuan Prefecture -- the composition and scale of the garrisons of Yanmen and Taiyuan were the same as those of the six prefectures of the Beiping Army, and they were all equipped according to the standard of one battalion of the "Flying Dragon Army" and one regiment of the "Security Army". As for one of the commanders of the southward extermination of the Han Dynasty, Zeng Zhilin, Yang Xin, and Mutel still returned to their original posts and did not directly participate in the restructuring of Yanmen and Taiyuan.

In addition to the work of integrating various prefectures and counties and forming Yanmen and Taiyuan, another important task of the Taiyuan Temporary Detention Office is to select a suitable location in the surrounding area of Taiyuan City and prepare for the construction of the third production base of the crossing team - this is also the reason why Li Junwu, Zhou Lei, Yu Wende, Liu Wendong and other key members of the Ministry of Science and Technology will go to Taiyuan with Zhang Weixin and Xu Shaoan.

The construction of a new production base near the city of Taiyuan was decided by the enlarged meeting of the committee after studying the needs of the crossing team and the actual situation that Taiyuan and Yanmen have always been important suppliers of thermal weapons for the crossing team. However, unlike the previous two production bases, the new production base in Thai Nguyen Province will focus on the production of weapons and equipment, especially chemical raw materials such as various firearms propellants and explosives, and will not involve the production of civilian products or military products other than chemical raw materials. After the relevant military chemical products are produced, they will be transported to the "Liangyuan" production base and the new production base in Beiping, where they will be combined with basic firearms parts such as shells and warheads produced there, and finally produce firearms for the armed use of the crossing team. …,

The reason for this arrangement is that Taiyuan and Yanmen are the production areas of pyrite, saltpeter and other raw materials of the crossing team, and the production of military chemical products here can save a lot of transportation time and transportation costs - it is far more cost-effective to transport finished propellants and explosives to Beiping City than to transport saltpeter and pyrite there; The second is also to take into account the need to keep the final firearm confidential and firmly control the final firearm through the core area of the team, so as to avoid the leakage of the finished firearm due to the production of multiple places.

The Beiping Army was in full swing, and at the same time, it was elated and morale-boosting to open the mansion and build the factory, but the Later Zhou court was gloomy and gloomy. As the king of a country, seeing that he was planning and planning the war against the Han Dynasty, during which he lost troops and lost countless money and food, the result was not only a failure, but he failed to fulfill his long-cherished wishes and ambitions, but instead made wedding clothes for others in a helpless situation, so that the Beiping army without a court and a king took the opportunity to take advantage of the fisherman's profit, and pocketed the land of the puppet Han Dynasty and eight states, so that the territory under its jurisdiction and the scope of Shili were expanded by nearly half compared with before. Chai Rong's mood can be said to be extremely depressed and bad. What made Chai Rong even more unhappy was that there was nowhere to vent and release this depressed and bad mood for a while. Because before the invasion of the Han Dynasty, most of the ministers of the court and the central government expressed an attitude of opposition to his dispatch of troops at this time, believing that it would be unfavorable for the country to use swords and soldiers in this season that was not suitable for war, and they all suggested that the time of the invasion of the Han should be postponed until the beginning of the spring of the following year. Zuihou still insisted on sending troops at this unexpected time for the Beiping army because of his stubbornness and strength, so as to solve the puppet Han court before the Beiping army made any moves.

Since it is his own idea to defeat the Han, the responsibility for the defeat of the war against the Han cannot be pushed to his own civil and military generals, but can only be borne by himself. In this way, the depressed aura that can't be emanated will naturally be depressed in the chest. In addition, the class teacher soon contracted some wind chill because he did not pay attention to the weather changes and did not add clothes in time. So under the dual effect of external feeling and internal accumulation, Chai Rong, who was depressed because of his unpaid ambition, finally fell ill on the way back to Kaifeng.

Moreover, because of the extremely bad mood, the march all the way and the lack of rest and recuperation, coupled with his physical condition was not very good, Chai Rong's illness was delayed for more than half a month, until the army returned to Kaifeng, there was still no improvement, and there was no sign of improvement.

Chai Rong was seriously ill, which made the concubines distressed, the vast majority of the ministers in the court and the central government anxious, and the imperial doctors of the Imperial Doctor's Department panicked, but also made a few ambitious guys who wanted to replace the Chai family begin to move. For a time, the dark tide above the court and Kaifeng City was surging, and the prospect was unpredictable.
