On May 14, the fourteenth year of the Great Cause (618), Emperor Yang Yu of Sui Gong finally gave up the throne to Li Yuan and returned to live in the palace. Although he was born in the emperor's family, he now has no capital to compete with anyone in the world, and his young experience is not enough, so he can only be manipulated by others at will, live in Chang'an, and be named the Duke of Xiguo.

On May 20, the fifty-three-year-old Tang King Li Yuan ascended the throne in the Taiji Hall and proclaimed the emperor, sacrificed to the sky, granted amnesty to the world, and changed the Yuan Wude. The establishment of the Tang Dynasty was 4 days earlier than the proclamation of Yang Dong as emperor in the eastern capital.

In May of the following year, Emperor Yang Yu of Sui Gong died at the age of 15, the cause of death was unknown, and he died of illness. This statement is debatable, as the bloodline of the old dynasty, he lives like a nail, and if he is not pulled out, it will make some people uncomfortable. In short, this poor young man died early, and the death was unbelievable.

At this point, Li Yuan re-established the feudal dynasty in Guanzhong and became the supreme ruler who occupied the position of Jiuding Zun. At the same time, according to the relationship between the five elements, it is presumed that the Tang Dynasty belonged to "Tude", so yellow was the most noble color. The county system of the Sui Dynasty was changed to the state and county system.

Li Yuan understands very well that "education is the foundation of the country", and sets up Taixue, four schools, and Guozixue, recruiting students, and the following states and counties also enroll students.

When a new dynasty is established, it is natural that a group of people will be promoted, so that everyone can perform their duties and govern the country well. Li Shimin is the secretary of the army, Qu Tutong is the secretary of the military department, Pei Lin is the right servant and the governor, Liu Wenjing is the acceptance of the words, Lonely Huaien is the secretary of the military department, Xiao Yu and Dou Wei are the internal history orders, Li Gang is the secretary of the Ministry of Rites, Yin Kaishan is the servant of the Ministry of Officials, Tang Tong is the servant of the internal history and a large number of people have been promoted and have become the pillars of the Tang Dynasty at the beginning of the founding of the country.

At the same time, the Tang Dynasty government abolished the Sui Dynasty's law "Great Cause Law" and promulgated the new dynasty law.

Li Jiancheng, as the eldest son, was named the crown prince, Li Shimin was named the king of Qin, Li Yuanji was the king of Qi, and his daughter was named the princess.

At the beginning of the Tang Dynasty, the most famous was Chai Shao's wife, Princess Pingyang, who had already mentioned her brave deeds of collecting troops to fight. When the Tang Dynasty was established, she was named a princess, and before she was crowned a princess, her name was not said in the history books, it was called Li.

Other clan members were also crowned kings, such as Li Shentong, Li Daoxuan, Li Xiaoji, etc.

Although Li Yuan successfully established his own dynasty in Chang'an, the world was still in a state of fragmentation at this time, and the peasant army was divided into one side. Li Yuan still has a long way to go if he wants to completely unify the world. Heroes from all walks of life want to compete in the Central Plains and win the overlord of the world.

Although Li Yuan and his sons took the lead in targeting Chang'an, the capital of the Sui Dynasty, and successfully made Chang'an their base, they were coveted by other heroes at any time. It's not ...... Less than a month after the establishment of the Tang Dynasty, they ushered in their first opponent who could not be underestimated - Xue Ju, if he had not been lucky enough to die early, maybe Li Yuan would have been proclaimed emperor in Chang'an, and it would have become a short-lived legend after all.

To meet Xue Ju's challenge, it is the first time to send troops after the establishment of the Tang Dynasty, this is a battle that makes their brains ache, if it weren't for God helping them, so that the fierce Xue Ju died inexplicably, Li Shimin is not necessarily his opponent,

Where is Xue Ju, a fierce man?

During the Great Cause of the Sui Dynasty (605-618), Xue Ju served as the captain of Jincheng Prefecture, and his temperament is described in historical sources as follows: magnificent appearance, fierce and good at shooting, and superb martial arts.
