There was a natural disaster that year, the river dried up and the fields failed to harvest.
In order to survive, my ancestor ate a white snake that was about to become an immortal.
Before dying, White Snake cursed: "Your descendants will be eaten alive by my snakes!"
One day a hundred years later, suddenly there were many snakes around the village. They stacked on top of each other and surrounded the entire village.
The white snake transformed into a villager and blended into the village.
Some of the people in the village were people, and some were snakes wearing human skins. I couldn't tell them apart.
While escaping, I accidentally discovered that my death would trigger the loop mechanism, and the time would go back to the first day when White Snake entered the village...
