Dragon Ball: The Simulated Life of a Low-Class Warrior

He transmigrates as a newborn Low-Class Warrior Saiyan, and he's Bardock's nephew. His father despises him from the start and nearly sends him into exile. Luckily, he awakens the Life Simulation System. By spending energy, he can simulate the future. After each death, he can choose to inherit either his combat power or his battle experience from the simulation. First simulation: accidentally killed by Raditz. Second simulation: shot down in a spaceship by Cooler. Third simulation: learns ki on Earth, then gets dissected in the middle of the night. Fourth simulation: gets killed after Vegeta sets him up. Fifth simulation: shares a Spirit Tree Fruit with Turles, then gets slapped to death by Slug. ...I'm up at the crack of dawn again! He dies, then starts over, again and again. It's victory or death. Finally, after his Nth simulation, as Frieza's army bears down on them, everyone falls silent at the sight of the little red-haired Saiyan before them... Five years until Planet Vegeta is destroyed. This time, I'm going to make every boss get up at the crack of dawn! > Dragon Ball fanfic / Transmigration / System simulations / Repeatedly switching sides / Goku, stop stealing my kills
