At the beginning of the third year of Yongxi (the sixth year of Datong in the Southern Liang Dynasty, 534 AD), Yuwentai successfully took over the political legacy of He Bayue without danger and became a powerful figure in the Guanlong region.
Because the Northern Wei Emperor Yuan Xiu also wanted to get involved in the Guanzhong region, he arranged Li Hu to Yuwentai's side. Previously, Li Hu went to persuade He Batsheng to no avail, and learned that Yuwentai had taken the place of He Batyue to lead all the soldiers, so he rushed back from Jingzhou. As a result, he was captured by Gao Huan's generals and sent to Luoyang when he passed through Ruxiang. As a result, he was rescued by Yuan Xiu, appointed him as General Wei, gave him a large sum of money, and sent him to Yuwentai, which only strengthened Yuwentai's strength.
The full-fledged Yuwentai immediately began to expand further, and the primary target was naturally Hou Mo Chen Yue. He first wrote a letter to Hou Mo Chen Yue, severely condemning him, asking him to see the situation clearly and surrender, otherwise he would meet each other. Later, in his reply to Yuan Xiu's strategy to stabilize Qin and Long, he pointed out the danger of Hou Mo Chen Yue, and that Hou Mo Chen Yue should be recalled and granted an official position in the capital, or one of the two states of Gua and Liang should be divided into two states. After doing this, Yuwentai officially started to act.
Yuanzhou Assassin Shi Gui was originally a close confidant of He Batyue, but after He Batyue was killed, he took refuge in Hou Mo Chen Yue. After that, Hou Mo Chen Yue sent Wang Bohe and Cheng Ci'an to lead 2,000 men and horses to help Shi Gui defend Yuanzhou, and Yuwentai then sent the governor Hou Mo Chen Chong to lead a thousand lightly armed cavalry to attack. Hou Mo Chen Chong took advantage of the night to bring only a few cavalry to the city, and the rest of the men and horses were ambushed on the nearby roads. Seeing that he had few soldiers, Shi Gui was defenseless, Hou Mo Chen Chong saw the opportunity to launch an attack and occupy the city gate, and with the help of Nei Ying in the city, he captured Shi Gui alive, Cheng Ci'an, Wang Bohe and others, and brought them back to Pingliang.
Soon after, Yu Wentai led a large army to attack Hou Mo Chen Yue, and various armies gathered in Yuanzhou. In April, Li Bi, the assassin of Qinzhou in the Northern Wei Dynasty and the Southern Wei Dynasty, saw that Yuwentai was menacing, so he persuaded Hou Mo Chen Yue to put down ** and apologize to them to protect their integrity, but Hou Mo Chen Yue ignored it. At this time, although the snow was serious, Yuwentai still led the team day and night, ready to surprise Hou Mo Chen Yue. After Hou Mo Chen Yue got the news, he led the army to retreat to Luoyang for defense, leaving only 10,000 people to stay in Shuiluo. But who knew that as soon as Yuwentai arrived, Shuiluo's men and horses surrendered, and then Yuwentai hurriedly sent light cavalry to Luoyang.
At this time, Hou Mo Chen Yue was already unable to advance or retreat, so he asked Li Bi to defend against Yuwentai with him. But Li Bi knew that Hou Mo and Chen Yue would fail, so he secretly contacted Yu Wentai and asked to be his internal response. Soon after, Hou Mo and Chen Yue abandoned the state city and retreated south, trying to occupy the mountains and risk protecting themselves. As a result, that night, Li Bi gathered his subordinates and said that Hou Mo and Chen Yue wanted to return to Qinzhou, and let everyone pack their luggage and act together. Because Li Bi's wife is Hou Mo Chen Yue's aunt, she is especially used by Hou Mo Chen Yue, and people naturally believe in his words. So Hou Mo Chen Yue's subordinates rushed to Qinzhou, and when they arrived at the gate of Qinzhou, they met Li Bi who arrived first, and as a result, under Li Bi's flickering, these people defected to Yuwentai with him.
Hou Mo Chen Yue wanted to make another last fight at this time, but the people's hearts were scattered, and the team collapsed on its own. Hou Mo Chen Yue had no choice but to flee with his son, son-in-law, and brothers. Originally, they wanted to go to Cao Ni, but they encountered Yuwentai's pursuit halfway, and the desperate Hou Mo Chen Yue had to hang himself.
Although Hou Mo Chen Yue died, his comrade Sun Ding'er, the assassin of Fengzhou, refused to surrender with tens of thousands of horses under his command, and Yuwentai sent the governor Liu Liang to crusade. At this time, Sun Ding'er thought that Yuwentai's department was still far away from him, so he did not prepare. Who knew that Liu Liang had arrived at this time, he first erected a big flag on the hill near the state city, and then led twenty cavalry into the city to put Sun Ding'er who was holding a feast. After killing Sun Ding'er, Liu Liangyao pointed to the banner outside the city and ordered the two cavalrymen to let the "army" enter the city. The people of the city were already frightened and stupefied, and they all surrendered at once without resistance. In this way, Yuwentai soon took the Guanlong region into his own hands.
After having a stable territory, Shi Yujin, the governor of Xia, made a statement to Yuwentai, hoping that he would state his interests to Yuan Xiu and let him move the capital to the Kansai region, so that Yuwentai could coerce the Son of Heaven to order the princes. Although Yu Wentai deeply agreed with this, he knew that this matter was not easy to operate, who would have thought that God would give him a big gift soon.
