Once you travel through time, the game comes to reality. In this world, everyone can change their job to a professional, and they can upgrade by downloading dungeons and killing bosses.
Su Xing changed his job and became the only immortal cultivator with a hidden profession. He was admitted to the highest university in Daxia. He thought that what was waiting for him would be a broad road, but Su Xing couldn't fight monsters and upgrade at all. After four years in university, Su Xing is still a small Qi training state. Graduation is difficult.
