Nie Li comes back with everything he learned and nothing he can prove, which means watching him rebuild from absolute zero hits different than standard isekai. The world-building pulls from actual Taoist philosophy instead of generic magic systems, so the spiritual mechanics feel earned rather than explained. The 5-minute episodes are brutal on pacing, but the plot moves fast enough that you forget you're watching in chunks.

Nie Li wakes up as his thirteen-year-old self with a startling advantage: memories of a lifetime spent becoming the strongest demon spiritist, before he died fighting the Sage Emperor and six deity-ranked beasts. Back then, he was too weak to save his home when it mattered. Now he knows what's coming. The problem is his current body matches his current age. He's the least talented student in his class, stuck with a feeble red soul realm. But knowledge is its own power. Drawing on everything he learned in his previous life, Nie Li begins training faster than anyone would expect, determined to regain his strength before fate can repeat itself. Demon beasts are set to ravage his city, and he means to protect his lover, friends, family and neighbors from that fate. He also helps companions who died nobly in his past life grow stronger, while setting his sights on the Sacred family who betrayed the city. Blending action, fantasy and romance, the story is about a second chance and whether knowing the future means you can change it.
