Dragon bastard(Dbz harem x male autistic reader)

Way before Beerus became G.O.D a man used the super dragon ball to become the stronguest being in the 12 universes. and he became so strong that even the stronguest time patroler Xeno Goku coudn't beated you. You loved your life so much you coudn't bare the fact of dieing so you decided to use the super dragon balls again after 1000 years later and you asked him to reincarnate at each death. And the dragon accepted. and 3000 years later you finaly died out of olderness and you reincarnated as a saiyan as the son of Son Goku.
