The Dawu Dynasty was a dynasty that built its country on martial arts. The realm of martial arts was divided into the body-tempering realm, the Tongmai realm, the Yuan-condensing realm, and the Huagang realm. Each realm was divided into nine levels. There are often barbarian invasions on the borders of the dynasty, and internal aristocratic families are competing for power, and undercurrents are surging. In the modern world, Chen Liu, a special soldier, accidentally triggered a mysterious ancient artifact while performing a high-risk mission. His soul traveled to the Dawu Dynasty and possessed the body of a frail and sick young man of the same name from a small landlord's family.
