Patriarch Green Leaf was a character in the novel,"Nine Provinces Immortal Transformation." A similar novel was recommended," The Founder of the Devil Dao." It told the story of the protagonist leading the rise of the Devil Dao through reincarnation. Those who liked fantasy immortal cultivation novels could read the Legend of Mortal Cultivation, which described the legendary experience of how a mortal cultivated to become an immortal. I hope you like my recommendation.
