Description

Zhang Xuan wakes up in a strange world with an unexpected profession: teacher. A mysterious library materializes in his mind, automatically cataloging the weaknesses of anything he encounters—people, objects, and creatures alike. Armed with this knowledge, he transforms from an ordinary educator into a formidable force, though his methods prove unconventional. Whether advising emperors on fashion, offering dubious lullabies to fairies, or suggesting dietary changes to demon lords, Zhang Xuan takes his role seriously. His journey becomes one of shaping the strongest experts in the realm through guidance and instruction, no matter how reluctant his students might be.
