It turned out that when Yuan Xi first returned to Youzhou, he already understood the internal situation of Karasuma, and the various departments of Karasuma were afraid of the strength of Bunton, and they were afraid that their tribe would be annexed, so they united to promote Louban to replace Bunton. Although Lou Ban is the son of Qiu Liju, he should be the first heir of Liaoxi Karasuma, but the strong suppression of Badun had to keep a low profile and forbear, until Yuan Xi sent Jia Xu to convince himself that as long as he sincerely cooperated with Yuan Xi, he could help him get rid of Badun and ascend to the position of Karasuma Shan Yu.

This is what Lou Ban never dreamed of, the opportunity came so suddenly, rather than being oppressed like this, it was better to gamble, so he agreed to Yuan Xi's request, as long as Lou Ban could ascend to the position of Shan Yu, he would lead the crowd to submit to Yuan Xi. Lou Ban is not as ambitious as Bang Dun, as long as he is given certain benefits, Lou Ban will not give up his rare wealth and fight against himself, so Yuan Xi decided to choose to support Lou Ban.

Lou Ban finally got his wish, successfully eliminated Badun, inherited the position of Karasuma Shan Yu, bowed to Yuan Xi, and obeyed the dispatch. Yuan Xi also led a large army into Liucheng, and then negotiated with Lou Ban about Karasuma's return. Yuan Xi had previously discussed with his advisers Tian Feng, Xu Shu and Jia Xu, and the first request was that the western part of Liaoxi should continue to be managed by the Louban, and he must take back the three counties of Shanggu, Yuyang, and Beiping, and the Karasuma army could only be stationed in western Liaoning, and the people of Karasuma could continue to live in the three places.

This requirement is also the most basic requirement for Yuan Xi to support Lou Ban's accession to the throne, and Lou Ban also promised: "Yuan Tingshi rest assured, in order to repay the general's great kindness, I will definitely let my Karasuma warriors withdraw from the three counties." Yuan Xi nodded, relaxed the conditions, and said: "In order to promote the friendship between our two clans, Lou Ban Shan Yu only needs to withdraw the army to Liaoxi, and the Karasuma people who are willing to live there can continue to live." Lou Ban expressed his gratitude to Yuan Xi and hoped that Yuan Xi would treat the people of Karasuma who continued to stay in the three counties equally.

Yuan Xi promised: "Please also ask Lou Ban Shan Yu to rest assured, I will treat the people living in Youzhou equally, whether they are Han or Karasuma, and also allow them to join the Youzhou Army, and the treatment will be more favorable." Then Yuan Xi put forward a second request, which was to establish a Han post station in western Liaoxi, and send Han envoys to enter Karasuma to spread Han culture and deliver news. This class naturally allowed, and he was also eager to learn the advanced culture of the Han people and improve the precarious life of the nomads.

The third requirement is to strengthen cooperation and trade between the two communities. The quality of the horses in Youzhou is insufficient, and the Karasuma people are good at raising horses, hoping to trade the good horses of Karasuma with grain and money. This is a mutually beneficial behavior, Lou Ban did not hesitate, willing to cooperate for a long time, and hoped that Yuan Xi could send someone to teach the life skills of the Karasuma Han people, and he was also willing to send a professional horse breeder to teach horse breeding skills. Yuan Xi was also very happy to see that Lou Ban took the initiative to learn the skills of the Han people, which could promote the great integration of ethnic groups, which was much more reliable than killing each other to resolve ethnic disputes.

The last thing to be solved is the issue of the army. Yuan Xi demanded that the army without its own order should not send troops privately, that the regular army in western Liaoning should not exceed 50,000, and that the Karasuma soldiers could apply to join the Youzhou army, and that they would be given the same treatment as the Han people, or even more generous. Although Lou Ban was willing to obey Yuan Xi's command, he did not want to be restricted by Yuan Xi's freedom to send troops, but pleaded: "Yuan Tingshi, I, the Karasuma warrior, am willing to be the vanguard for you, expand the territory, and I also hope to give you the right to send troops freely." ”

Yuan Xi saw that Lou Ban still had the idea of expansion, and he was suddenly unhappy in his heart, and he kept staring at Lou Ban, and Lou Ban was panicked, and then his tone was a little cold, and he said: "Karasuma is my best ally of the Han Dynasty, I hope that Lou Ban Shan Yu can focus on the overall situation, and don't act rashly and cause instability on the border." If you need Karasuma's help, Captain Yan Rou will convey my orders, so you don't have to worry too much about it! Lou Ban Shan Yu saw that Yuan Xi was resolute, and he also knew that Yuan Xi was afraid that his growth would be detrimental to him, and he would definitely not relax this condition, so he didn't mention it again.

After negotiation between the two sides, and then Lou Ban passed Yuan Xi's words to the Karasuma soldiers, at first the Karasuma soldiers were still very resistant to the Karasuma army could only operate in western Liaoning, and later heard that they could sign up for the Youzhou army, and the treatment was much better than the Karasuma army, Shanggu, Youbeiping and Liaodong Karasuma soldiers have signed up to join Yuan Xi's army, Yuan Xi ordered Zhang Liao to form an army of this group of Karasuma warriors, under his separate command, Zhang Liao is very grateful to Yuan Xi for his attention, and has been accustomed to life in Youzhou. Zhang Liao and Yuan Xi had an agreement, that is, after taking refuge in him, he didn't want to be an enemy of Cao Cao, so Yuan Xi just asked him to lead the Karasuma army to guard the northern frontier.

Yuan Xi's Youzhou army was stationed in Liucheng for a few days, helping Lou Ban stabilize the situation in western Liao, appointing Xian Yupu as an envoy of the Han Dynasty, and building a Han post station with Yan Rou, responsible for passing on the cultural exchanges and trade activities between Youzhou and Karasuma, and of course supervising Karasuma Shan Yu. Lou Ban also sent an order to the Karasuma army stationed in the three counties, ordering them to withdraw to Liaoxi and return control of the three counties to Yuan Xi. Yuan Xi also successfully took over the three counties and began the restoration work of the three counties, appointing Zhang Liao as the county guard of Shanggu, Tian Chou as the county guard of Beiping, and Sun Li as the county guard of Yuyang.

Although Yuan Xi did not have a history of Youzhou assassination, in fact, there were only Fanyang County, Zhuo County, and Dai County under his rule, and Jixian County, Fanyang County is the center of Youzhou, and it is also his base camp, and Zhuo County and Dai County are close to the border pass, mainly Touch Jiao and Zhang Nan guards, at present, the two have not betrayed themselves like in history, and there is no need to replace, mainly because of the lack of replacement talents. Now there are three more counties, which is equivalent to doubling the power, but there is still a long way to go before the entire territory of Youzhou is subdued. The remaining Changli County, Liaodong County was still in the hands of Gongsun Du, Xuansu County was occupied by Goguryeo, Lelang County was occupied by Baekje, and Obibang County was occupied by Silla, so Yuan Xi's next target was Gongsun Du.
