In a high-martial arts world where everyone changes jobs, Ling Yun awakens the unknown Zhong Kui profession, is mocked as the most useless, and is sent to the nine-deaths-and-a-live mass grave. Who knew this sole mythical profession specializes in curing demons, binding the system to absorb ghost energy and level up? The nobles laugh at him for seeking death, but the ten thousand ghosts of the mass grave kneel to welcome him as their master. From a good-for-nothing mocked by everyone to shocking the world in the name of the Heavenly Master, Ling Yun's counter-attack path begins from a mass grave.
