Gu Chang'an transmigrates into a vast world of immortal cultivation and awakens an Immortality System. Every year he sleeps, his lifespan increases by one year, and he also gains an attribute point. Gu Chang'an has no interest in fighting and killing; he just wants to sleep peacefully and, along the way, see old friends off on their final journey. After sleeping for ten years, his former village has changed beyond recognition. After a hundred years, the dynasty of old is gone. After a thousand years, the flowers he casually planted have become precious spiritual herbs fought over by countless cultivators. After ten thousand years, the little bird he once raised has become a demon emperor ruling over an entire region.
