A sudden earthquake swept Lin Yan, an ordinary college student, into a rift in time and space. After waking up, he came to the Canghuan World where professionals were respected. Here everyone awakens to their profession, magicians, warriors, priests, assassins, and summoners each go their own way, and fitness determines the starting point. Alien beast materials, secret treasures, college guilds, and the Holy Glory Church jointly support the cruel order. Lin Yan's test result was only "Unknown occupation, E-level fitness." No one knew that what he really awakened was the hidden profession - Rift Walker. In order to return to Earth, he could only hide the crack in his left wrist and collect fragments of time and space tokens from beast tides, pollution, auctions and rift instances. From being cautious to survive, to leading the team to break the situation; from being a low-key observer, to stepping into the academy. This other world wanted to keep him, and he had to find his own way home.
