Lin Yan, a loser entrepreneur with terminal cancer, was reborn in the Xuanhuang world after his death. He used modern cognition to reconstruct Taoism, cast traditional Chinese medicine meridians, AI modeling and metaphysical visualization, and created a unique "contemplation method". Starting from farming and raising younger siblings, he became stronger in the chaotic world of martial arts, and finally proved that "gods and demons are not external objects, that is, the mind is the body and is the Tao", and he lives forever.
