In Wangyou Valley, a forgotten little mountain village on the edge of the Immortal Realm, the protagonist Lin Du is a laid-back young man from the twenty-first century who transmigrated there. In a world where everyone cultivates immortality and competition is relentless, he chooses a different path: he has no desire to ascend to immortality and only wants a carefree life in the mountains.
Though cultivation resources are plentiful in this world, an accident three hundred years ago made the spiritual energy between heaven and earth unusually gentle. Cultivation no longer requires fighting and killing to seize resources. Instead, it depends on a peaceful state of mind and living in harmony with nature. Lin Du unexpectedly discovers that the lie-flat attitude and laid-back wisdom he brought from his previous life happen to align with the Great Dao of Heaven and Earth, and his cultivation improves by leaps and bounds without him even noticing.
The spiritual tea he grows helps an elder who has cultivated in seclusion for a hundred years attain enlightenment. The home-style dishes he casually cooks can regulate the chaotic spiritual energy of cultivators. Even the little tune he hums while sunbathing becomes a "Heart-Cleansing Mantra" that helps others overcome their inner demons.
