In the early days of the founding of the People's Republic of China, there were hundreds of wastes waiting to be renovated, and it was also a time when ghosts and monsters were dormant and undercurrent. Under the black soil of Northeast China, there are far more than dead bones and history buried.
Zhang Muzhi, an orphan who was abandoned in front of the Guandi Temple, possesses the rare "Buddha Bones and Tendons", but is entangled in a mysterious "underworld contract". He is born with a loss of yang energy and needs to use merit to survive. In order to survive, he had to become a disciple of a reclusive Mr. Chu Heier and practice both Buddhism and Taoism.
The "Enlightenment Chapter" on the left hand refines Qi and transforms into gods, and the "Shrangama Mantra" on the right hand subdues demons. A mahogany sword cannot cut off a century-old mandrill, and a vajra pestle cannot knock away a thousand-year-old vengeful spirit. Earning merit can not only strengthen your cultivation and prolong your life, but you can also redeem magical secrets, magic weapons and elixirs in the underworld's "merit book".
From the "small disasters" in the deserted villages and graves, to the "Ghost King's Cave" deep in the Xing'an Mountains; from saving lonely souls and wild ghosts, to confronting the evil cultivators who steal the country's destiny. Zhang Muzhi wanders on the edge of Yin and Yang, dealing with immortals, Buddhas, demons and ghosts.
He is the seed of Buddhism in the eyes of Taoists, the true successor of Taoism in the eyes of monks, the impermanence in the eyes of demons, and even a "special temporary worker" recorded in the underworld.
Let's see how this different "Mr. Chu Heier" carves out his own path to heaven in the dark side of the turbulent times, and finally reveals the shocking secret behind the contract.
