Summary of the story: Shen Fei in modern society accidentally transformed into a prisoner of the devil whose spiritual roots were destroyed and was about to be executed in the world of immortality. In a desperate situation, he activated the "Knowledge Exchange System of All Realms", which allowed him to exchange items from the realm of immortality for knowledge and skills from all realms. While others were practicing spiritual energy, Shen Fei used high school physics to crack the mountain-protecting formation, used the barefoot doctor's manual to treat difficult and complicated diseases, and relied on a mouth and knowledge from thousands of worlds to perform dimensionality reduction attacks in the cannibalistic world of immortality.
