At the end of the great cause, wars broke out all over the world. Emperor Yang Guang of the Sui Dynasty was tyrannizing the people, and rebels against the king rose up in various places. However, behind this mortal war sweeping the world, a deeper darkness is quietly growing. Demons that feed on human resentment, war, and despair quietly infiltrate the world, fueling the flames of troubled times.

During a mission to Wagang Village to investigate monsters in the army, he was helplessly involved in the huge vortex of mortal heroes and behind-the-scenes demons. He will have to face a choice: continue to work for the decaying dynasty, or work with those reckless heroes who are destined to create a new era to find a new way to cut off the chaos between humans and demons.
