Immortality: I Have an Infinite Lifespan

(Immortality + farming + no female lead + no System + plot-driven + scheming + keeping a low profile) Tang Chen, a mighty cultivator from the Dao Realm who has lived for ninety thousand years, finds his immortal life unbearably dull. He uses the Ninefold Soul-Revival Art to reincarnate and enters the Tianyuan Continent. Stripped of his memories and powers, he begins a new journey toward immortality. In the Tang family of Sacred Soul City, he starts from scratch, tempering his body, gathering spiritual energy, tending his fields, reading books, and raising spirit insects. With an endless lifespan, he gradually becomes a supreme powerhouse. This time, he finds the true meaning of immortality.
