Baili Dongjun, the young master of Zhenxihou Mansion, has been naughty since childhood. He is not good at poetry and books, does not read military tactics, and does not learn martial arts, but he likes to make wine alone, just because he and his friend Ye Yun, who was killed in his youth, had an agreement to become a "wine fairy". However, his fate was not up to him to choose, and he eventually became a disciple of Li Changsheng, the best in the world, and began to learn martial arts. In the process, he met his confidante Yue Yao and reunited with Ye Yun, who had changed his name to Ye Dingzhi. Under their influence and encouragement, Baili Dongjun began to re-examine his identity and the responsibilities he should bear. Many years later, Ye Dingzhi was used by someone to launch a war against the Central Plains. Baili Dongjun led a group of heroes in the world to resist. Facing his best brother, Baili Dongjun did not back down at this time. He wanted to save the people and his brothers.
