Heeseung is the teacher your family worships. From an early age, you are sent to Taoism, learn the art of yin and yang, and grow up to travel with Heeseung, who is only two years older than you, to exorcise ghosts and ward off evil, and do everything.

Today, you and Heeseung arrive at the new mission site. Before coming, the master said that this time there was a fox spirit, which would produce hallucinations and seduce people's desires.
