After I Was Reborn, I Became His Deadly Poison

Looking for Infinite-Flow Stories

Please help me find a book. I'd like an infinite-flow story, preferably with an ensemble cast, though that's not essential. Most importantly, no power fantasy and no golden finger. I'd like something logical. I've read so many stories that start strong and go downhill lately, wasting way too much of my time. Anything else is fine. Thanks so much!
