Wuh zhao (This appears to be a name or a term that requires more context for accurate translation. It's likely a Chinese name or a term from a specific field.)

In the 19th century, he was a 30-year-old man, Wu Zhao, who was extremely cruel and decisive in his actions. Indeed, he began his journey as a teacher at an academy school, making all students fear his defiance, and even others were unable to learn from him. Only after reaching Soul Formation did he calm his true nature as a killer.
