Why did Chu Qiao Chuan Yan Xun abandon the United States to join the army?
In fact, from Xun Yan's point of view, it is beneficial for him to give up the US military. He may also decide to give up the US military from the overall situation:
1, Li Xiujun is a rebel: because Li Xiujun opened the city gate for Zhao Dongting when he led troops to wash Yanbei blood three years ago, he was a sinner, and the sinner was not worthy to go back to Yanbei with them. For Xun Yan, the rebellion of Li Xiujun was not true, but after all, the city gate was opened, so it was a rebellion in Yanbei, and the rebels needed to be punished.
2. Stall time with a beautiful army: Xun Yan doesn't have many troops, so it is difficult to resist the pursuers of the great Wei Emperor. There are many beautiful troops, so we can at least mediate with the troops in the city to win more time for Xun Yan's escape.
3. A beautiful army needs atonement: For Xun Yan, the existence of a beautiful army is used for atonement. Xun Yan forgave why he laughed and others because Yan Xun was short of manpower in Chang 'an, so for Xun Yan, the purpose of the beautiful army was just to ensure Xun Yan's return to Yanbei.
Xun Yan three years ago and Xun Yan three years later are no longer alone. The whole family was killed and Yanbei was slaughtered. Three years later, Xun Yan was a heartless person. The purpose of his life is to avenge Chang 'an.
Did Chuqiao go back to Yanbei with American troops?
After Chu Qiao knew that he had given up on them, he returned to the East Gate. She said she would take Li Xiu's army home, and she did. Finally, she returned to Yanbei alone with the Li Xiu army.
It is because of Chu Qiao's promise that the US military has always been loyal to Chu Qiao.
In fact, when Chu Qiao returned to Dongcheng Gate to save the American troops, he could guess that there was already a disagreement between Chu Qiao and Yan Xun, which should also be the foreshadowing of a break between Chu Qiao and Yan Xun in the future.
