Headmaster Cao's name was Cao Xian, and he originated from a well-off family. His parents didn't wish for him to work hard his entire life and only wanted him to relax and enjoy life happily. Hence, they gave him the word 'Xian' (relax/idle) in his name.
However, things were contrary to their wishes. Cao Xian loved to read and after entering school, he became extremely interested in alchemy. He would use over ten hours every day to experiment in the lab. He wasn't idle at all.
After he graduated, he became a teacher and held a teaching position. Then, he became the headmaster of the Myriad Daos Academy. On his path, Cao Xian had never even relaxed for a single day. He always said that by giving him this name, his parents were actually cursing him, causing him to actually work even harder in his life.
However, Cao Xian was fond of such a lifestyle. He felt that only by having a fulfilling lifestyle would one be able to experience life.
