Chu Jin burned the ancestral tablet in front of everyone at his grandfather's funeral, which caused the howling wind, the roar of the ancestor spirits, and the whole clan to be shocked. Only Yu Xiao stood in front of the coffin wearing a black robe, with blood on his fingertips to draw a life-defying talisman, and whispered: "What you are burning is not a tablet, but a soul-locking chain." It turns out that all the ancestors of the Chu family were prisoners, sealed in the tablets to protect future generations from disaster, and Yu Xiao was a coffin keeper for thousands of years, specially coming to cut off the poison of this bloodline. When Chu Jin lit the last wisp of incense with his own hands, the door to the underworld opened and hundreds of ghosts roared - he was not a traitor, but the only one to untie the bell.
