Ling Jue, an ancient book restorer, is a modern young man who works conscientiously. However, due to his father's ravings, he steps into the isolated Kirigakure Village and inherits his grandmother's house.
This village surrounded by mountains hides weird secrets: the taboos after sunset, the extra demon-locking towers in ancient paintings on the walls, and the swollen faces emerging from the wells all point to the legend of water evil spirits from five hundred years ago.
The blood jade and ancient books left behind by my grandmother revealed that Taoist priests in the Ming Dynasty sacrificed young girls to seal away the evil spirits, but the so-called "sacrifice" was actually a massacre that continued the curse.
With the arrival of female reporter Cheng Qing, the two discover that under the Demon Locking Tower, which the villagers have guarded for generations, not only suppresses the resentment of the drowned girl, but also hides the truth that the grandmother faked her death - she was originally a spare sacrifice, exchanged for blood jade and spent her life researching to fight against the evil spirit.
When the two jade stones come together, the evil spirit in the underground river at the bottom of the tower breaks through the seal, the villagers' disguise is torn apart, and the thousand-year grudge between the outsiders and the guardians comes to light.
Ling Jue must use blood and blood jade to reforge the seal before the total lunar eclipse. But he doesn't know that he is already the ultimate chess piece laid out by his grandmother. He has been reincarnated for five hundred years just to wait for his arrival.
Mission: The truth will eventually come out
