The world of martial arts, the Dynasty of Dayu. The royal family has declined, and among the nine states in the world, only the three northern states can actually be controlled. However, even so, some people still do not give up. The borders of the three states are still being fought every year, and the people are living in dire straits. Of course, all this has nothing to do with Yu Mingyuan for the time being.

Yu Mingyuan's biggest headache right now is that there are always people trying to assassinate him, and he doesn't even understand how much his "predecessor" was hated...
