How did Xue, a white-robed teenager in the Tang Dynasty, establish his military position?

Li Xue, whose real name is Gui Ren, is from Longmen County, Shaanxi Province. Originally, my father was in charge of business and his family was relatively well-off. Because Luo Cheng, the white tiger star, was shot to death by random arrows, which disturbed the hell, Yan had no choice but to arrange the reincarnation of the white tiger star, and the white tiger star possessed Xue. He was frightened to death when he saw a white tiger behind Xue. Since then, his family has declined. Xue only likes practicing martial arts, and his appetite is much larger than ordinary people. When the family fortune fell, relatives were afraid to associate with Xue for fear of avoiding it. Later, Xue had to come to Mr. Liu's house to work for a living. Miss Liu (Liu) is kind-hearted and takes special care of Xue. It snowed heavily in winter, and Xue was only wearing light clothes, so Liu gave his father's big fur coat to Xue to keep out the cold. But when Mr. Liu saw it, he kicked Xue out, suspected that Miss Xue had an affair, and scolded and beat Miss Liu. Fortunately, under the persuasion of her elder sister-in-law, Liu didn't kill her, but just kicked her out of the house. Fortunately, Xue's sworn brothers settled them down and married them. They were very loving.

During the reign of Emperor Taizong, Dongliao sent someone to pick up the gauntlet. At the suggestion of Xu Maogong, Emperor Taizong decided to use personal expedition. On this day, Zhang Shigui went to Shaanxi to recruit soldiers. Xue heard the news of recruiting and joined the army with several other sworn brothers, but when he saw Xue's name, he refused directly. It turned out that Emperor Taizong had a dream not long ago. The military adviser told him that the emperor would be escorted by a sage who should dream, so Emperor Taizong made a decree to recruit soldiers in Shanxi. I wanted my son-in-law to pretend to be a good minister, so I refused Xue's request for the first time.

On his way home, Xue suddenly met a tiger chasing a general. Xue stepped forward to save the tiger. It turned out that Cheng was passing by on business. Xue saw that his martial arts were superb and asked? The strong man is so good, why not join the army? ? Xue told Cheng about his refusal to join the army. Cheng gave Xue a gold medal direction and told him to show it directly to the company commander. Xue got the treasure and thanked Cheng again and again.

The next day, Xue came to the military camp, found the company commander, and handed over the direction of Cheng's gold medal. Seeing the trend of Cheng, I had to accept Xue's intention. But make up a reason that the emperor dreamed that a young man was going to rebel, so when he saw that Xue was coming to join the army, he copied his family, so he wronged you to be a flaming army for the time being, and I interceded for you in front of your majesty until you made meritorious service in the future. Xue was puzzled, so he and his sworn brothers started the flaming army.
