Li Yun grew up with a system that gave him useless gifts. He wanted a reward that could prove the existence of the system, but ended up with abstract gifts like culture. Without physical proof, he was stuck wondering whether his mind was truly sane, all the while dealing with the reality of life and cultivating his own path. How will the "useless" system help Li Yun navigate medical school, hospital politics, criminal cases, treasure hunting, farming, and cooking? Author's Note: This is a slice-of-life novel chronologically detailing the life of a doctor with a mission-type system. It's written as a faux modern Chinese novel, so there are many 1-off characters and episodic mini-arcs. Book 1 and 2 are available on Amazon. Copyrights of the novel and cover are owned by Chocomug. Novel is free to read and download for personal use, such as offline reading, only.
