Review Detail of ChadFacts in Sage's Cultivation: Mage in Cultivation World

It's great but could use work on the main character. Loved all of the novel except the main character. He's meant to be some genius mage who is immortal... but he talks like a plain teenager and he doesn't seem very intelligent? He's meant to have the title of Sage but he's not inquisitive? The closest to wanting to learn new things he gets is just being interested in cultivation. Which, that part of him being interested in cultivation seems quite forced. It should be more smooth and gradually interested in cultivation. Instead, he's foregoing all magic immediately to learn about something he read in a book once pretty much.
