Haunted by a tragic past where he failed to save his home, Nie Li rebuilt himself into an unparalleled Demon Spiritist – only to meet a devastating end battling formidable foes. Now, mysteriously reborn as a thirteen-year-old, he finds himself at the bottom of the class, possessing seemingly meager abilities. Yet, armed with the memories and knowledge gleaned from his previous life, he’s determined to accelerate his training beyond anyone's expectations. Driven by a fierce resolve, Nie Li isn't just focused on personal power; he intends to uplift those who perished in his former timeline, guiding them towards strength. His ultimate goal is to avert the catastrophic destruction of his city – a fate he witnessed firsthand – and safeguard the lives of loved ones, friends, and fellow citizens lost in the previous beast assault. He also seeks retribution against the powerful Sacred family, whose betrayal and dereliction of duty contributed to that devastating loss.
