During the reign of Tang Zhenguan, the king of the day, Xue Rengui, came to Beijing by order to accompany the king. He didn't want to be framed by his uncle Li Daozong. He went to the court three times and risked his life. Although he finally recovered from the injustice, he was dispirited and discouraged. After returning home, he pretended to die and buried his name. He was determined not to be an official. It coincided with the invasion of the Tang Dynasty by the six West cool nations. Tang King Li Shimin was determined to conquer West cool by his personal expedition. In order to be talented, strategist Xu Mao tricked Xue Rengui into acting as Grand Admiral of the Expedition to the West. There are numerous dangers and difficulties on the west road. Many officers and soldiers shed their blood in the battle array. Many heroes fought to the death. The Xue family fought bravely for three generations. All the heroes shed their blood to break the west cool. This brought peace to the prosperous time of Zhen Guan, and the Tang emperor's triumphant song was still in the court.
