The world of cultivation has encountered "spiritual pollution". In order to maintain their cultivation, the monks had to take pills full of erysipelas, which made everyone manic, irritable, and obsessed. In this world, "edible natural food" is a luxury and an antidote.
The heroine's golden finger: Shennong's bloodline/Five Elements Spiritual Field space.
The radish she grows can extend life, the rice she grows can increase spiritual power, and a plate of vegetables she stir-fries is more effective than a sixth-grade elixir.
She doesn't need to meditate hard, farm, or cook, and her cultivation level will increase on its own.
Um, the ending is a bit sad.
