What will be the consequences if Buddhism's plan to learn Buddhist scriptures is ruined? Xuanzang of Tang Dynasty was a good man who practiced cultivation for ten generations, but what he got in exchange was the meat of Tang Monk that made demons and ghosts salivate. What is the cause and effect? Thirty-six transformations of Tiangang and seventy-two transformations of Earthly Evil, which one is stronger and which one is weaker? At the pinnacle of demon cultivation, can he shake the gods and Buddhas who are all over the sky...
