Wu Chuan was accidentally involved in a strange storm surrounding the "Tomb of the Marquis of Zhenhe". By chance, he found a bronze talisman from a scrapyard. From then on, he was haunted by the river ghost, and a strange red rash with the word "water" appeared on his arm. In order to unravel the curse, he followed his experienced third uncle Wu San on a thrilling journey to explore the coffins in the Heishui River, the human sacrifices in Broken Dragon Cliff, and the bell coffins in the underground river.
The tomb contains a shocking secret from three hundred years ago: the Marquis of Zhenhe was not a capable official in controlling floods as in the legend, but an ambitious man who used corpses to feed river ghosts and tried to use the underground river as a place to raise corpses. Wu Chuan and his third uncle encounter living corpses, corpse puppets, and river ghosts in the ancient tomb, and discover that every step of the adventure seems to have been planned in advance by the owner of the tomb - from the bronze fish charm of the blind old man in the ghost market to the descendants of the tomb guardians sacrificed at Broken Dragon Cliff, they are all a closed loop of "three in and three out" sacrifices.
When Wu Chuan discovered that the fish-shaped mark on his arm was actually the key to the real tomb, when the living corpse in the bronze coffin rang the soul-inducing bell, and when the golden light of the jade cong illuminated the conspiracy deep in the dark river, he realized that the so-called tomb robbery was just a "closing net" set by the owner of the tomb that spanned a century. And these intruders have already been targeted as "sacrifice".
