In Huaiyin Town of the Republic of China, there is a taboo old saying that no one dares to say:
The locust flowers bloom for a season, and the river water feeds one person. People die every year, and the weather is good every year. The truth about the stability and prosperity of the people in the town is shocking:
A hundred years of secret sacrifice, feeding the river in exchange for life.
All outsiders are sacrifices.
A floating corpse floated out of the shallows. It looked like a murder case, but in fact it was a sacrifice. An ex-convict returns home to investigate the case, and the more he investigates, the colder he becomes——
There is no evil at work, but the whole town is evil;
There is no demon to confuse the world, but it is a nightmare for people's hearts.
