Lin An was transported to an ancient farmhouse.
Good news: He can see the Qi on top of people's heads. White energy represents ordinary people, green energy represents noble people, and black energy represents the calamity of death.
The second uncle who gambles in the village always has ashes on his head, and the town's provincial government official has green hair on his head. Lin An squatted on the base of the stove and figured it out - in this world, people with white energy spend their lives farming, while people with green energy sit in sedan chairs and receive kowtows. He wanted his mother to stop being called a "hen that doesn't lay eggs", his father to stop working as a cow or a horse, and his two sisters to stop being sold for bride price.
Then you have to turn the white air on your head into green.
