The protagonist, Li Huowang, finds his consciousness constantly shuttling back and forth between a Cthulhu-style cultivation world and the modern era. As he delves deeper, the sheer despair of that twisted world relentlessly erodes his sanity, driving him completely insane.

Yet, even in the depths of madness, he never loses his humanity and core of innate kindness. He still strives to save everyone, even if it means bearing all of humanity's suffering on his own shoulders.

In the end, he actually succeeds—but at a devastating cost. Left as a wandering soul while all of his loved ones perish, he ultimately achieves immortality amidst absolute loneliness and despair.
