After Being the Sun for Five Billion Years, I Cultivated Immortality

I've been the sun for billions of years and grew utterly weary of existence. Until I collapsed into a black hole, opened my eyes, and found myself reborn as an infant in a world of cultivation. They tested my spiritual roots, but the spirit stone showed no reaction. Sensing something missing within me, I thought... and my spiritual roots simply grew on their own. They taught me spells, and I mastered them with a single glance, even refining them effortlessly along the way. They said my killing intent was too strong. I replied, "Ladies and gentlemen, please die right here." I only wanted to live as an ordinary cultivator, but everything seems to have gone awry?
