Book of Reincarnation: I Treat Myself as My Grandson!

Traveling through the world of cultivation, I reincarnated in my descendants for nine lifetimes. When he woke up in his second life, he found that he had become his great-grandson. The old man who was "myself in the previous life" still lives in his mind. ——I guide my own cultivation, I act as a golden finger to myself, and I act as a grandson to myself.
