Fang Yu, an ordinary office worker from modern Earth, awakens in the brutal world of 'Eternal Life,' specifically within the Fang Family of the Great Li Dynasty. Here, life is cheap; righteous sects enslave masses for faith power, while demonic cultivators sacrifice billions to refine treasures. Recognizing this dangerous setting and the future rise of the notorious Fang Han, Fang Yu realizes he cannot rely on known plot armor meant for others.

Fortunately, he possesses a mysterious cheat: the Myriad Worlds King Map. This artifact allows him to traverse infinite dimensions, including the terrifying 'Covering the Sky' universe. Starting as a lowly disciple at the third stage of physical cultivation, Fang Yu must navigate clan politics, survive ruthless sects, and harness the resources of countless worlds.

With determination and a proactive mind, he begins his journey from a fragile mortal to an invincible existence who shakes the very foundations of the heavens.
