Light Thief

Because I wanted to live three more years to unify the world before I died, so I turned into a 17-year-old kid and was arrested to cultivate immortality? ! What's even more outrageous is that I actually still have a 47-year-old max-level handsome man who kills people without blinking an eye, living in my mind! Accidentally activate second consciousness! During the day, I am the sunny little junior brother who is all-around good-natured; at night, I seamlessly switch into a ruthless tyrant commander! The ancient monster was greedy for my body and wanted to absorb my physical abilities. I used a little trick to successfully reverse it. He became my nourishment, but he counterattacked before his death and merged into my second consciousness!
