Who Is the Real Demon Mage?

My name is Lu Fengnian, a great mage from the ninth century. I only remember that the second time I died in a battle at sea, the specific cause of death is unknown. As for where he died for the first time, the cause of death is unknown. When I time-traveled into a 12-year-old boy, I discovered that in Rongcheng, the four major families have so many secrets. Gradually I discovered that I could actually go back to the Age of Discovery again... This is my first time writing a male video, so please forgive me if it's not good.
