Dragon Ball: My Sharingan Dominates

Waking as young Wu Tian, future Turtle Hermit, I found myself 300 years before Goku's birth, watching my master fall to the Great Demon King Piccolo. Humanity's hope hinged on a desperate, failing seal. But I'm no ordinary martial artist; I'm an Uchiha from another world, armed with the Sharingan and the forbidden knowledge of chakra. With a single, mind-bending glance, I created the opening my master needed. Now, with Piccolo sealed and 300 years stretching before me, I must cultivate a unique blend of Ki and Chakra. Can I, with stolen eyes and a changed past, truly prepare this world for Saiyan conquerors, galactic tyrants, and gods of destruction, or will my interference only unleash an even greater, unforeseen calamity?
