At the end of the Sui Dynasty and the beginning of the Tang Dynasty, the world was in chaos and the heroes were divided. Li Yuan and his son seized the opportunity, took advantage of the situation, and finally settled in Chang'an and established the Tang Dynasty. However, after the founding of the Tang Dynasty, this emerging empire that stood on the ruins of the chaotic late Sui Dynasty faced unprecedented challenges. The unification of the Tang Empire had a long road ahead. Faced with such a difficult situation, Li Shimin, the King of Qin who was given the important task of "helping the world and bringing peace to the people" since his childhood. He was born with the appearance of a dragon and a phoenix, and stood out from the sky. He took the initiative to shoulder the heavy responsibility of resisting foreign enemies and conquering the Central Plains. With his indomitable fighting spirit and unswerving innocence, he continued to fight against all odds. He continued to defeat Xue Rengao, Liu Wuzhou, Wang Shichong, Dou Jiande and other separatist forces, and finally fulfilled the Tang Dynasty's long-cherished wish to pacify the world. Li Shimin also grew up from the "Taiyuan Young Master" in bright clothes and angry horses to the powerful "Tiance General" in the turbulent times in the baptism of blood and fire.
