There is an isolated village on the bank of the Yellow River. Under the old locust tree at the entrance of the village is a hunchbacked black coffin that sank in the late Qing Dynasty. For hundreds of years, people have drowned in the river every few years, with their backs bent and their bodies curled up like shrimps. The seventh deceased was Chen Yan's uncle.
He inherited the "Shou Yu" left by his uncle - a gray-white jade pendant that burns when exposed to evil and glows when exposed to evil. On a rainy night, the old locust tree collapsed, revealing the bottomless Suolong crypt. Chen Yan went down with jade and saw the hunchbacked black coffin wrapped in iron chains deep in the cave filled with ancient Yin symbols.
Something was moving inside the coffin. The sound of nails scratching the coffin came from the ground one after another.
The bloodline of the coffin keeper has awakened, and the things in the coffin are also awakening.
Intention: The fate and salvation of the coffin keeper: Some things cannot be guarded if you want to, but someone has to guard them.
