I Inherit the Yin Yang Shop at the Beginning, and I Become the Living King of Hell in the Underworld.

His grandfather died suddenly and mysteriously, and Shen Zhao was forced to take over the ancestral Yin Yang shop. He originally wanted to live a low-key life, but was involved in the urban supernatural whirlpool because of a book about Yin and Yang's cause and effect—— The red-clothed ghost knocking on the door late at night, the afterlife elevator underground in the shopping mall, the wailing ghost on the top floor of the school... Every time he resolves the evil spirits, he is pushed deeper into the quagmire of cause and effect. Grandpa's death was not an accident, but actually involved a shocking transaction between humans and ghosts a hundred years ago, and the book of cause and effect in his hand was the key to the door to the underworld! What shocked him even more was that the Valkyrie Gu Qingluan of the "Exorcism Alliance" who had always been his enemy was actually the reincarnation of the "Suppressing Evil General" who was sealed by his ancestors of the Shen family! When Shen Zhao stepped into the underworld holding the bronze compass left by his grandfather, he was shocked to realize that he had already been marked as a "judge in the underworld" by the underworld! In the gap between the human world and the underworld, he must cut off all causes and effects, use the most ruthless means to eliminate demons and demons, and re-establish the order of Yin and Yang with sincerity and justice. Otherwise, there will never be peace in the Three Realms! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
