Two Realms of Dust

Lin Xuan, an ancient loose cultivator, survived for eight hundred years and was shocked to death by the aftermath of the Great War. When he opened his eyes again, he became a high school student in 2025. This world is very strange - although spiritual energy is thin, some people have seen dragons; although science is supreme, some people believe that Feng Shui can change their lives; there is also a legend called 749 Bureau, which is said to be true. And those "old guys" who have lived for thousands of years, who once guided Dayu to control floods and assisted Emperor Qin to unify, are now hiding somewhere in the world. Lin Xuan originally wanted to keep a low profile until he discovered—— This world is not quite right. It is a cave created by the One Powerful One. The way home is somewhere.
