I Traveled to Dragon Ball, but I Don't Have a Golden Finger

Ahhhh, why do other people travel through time and space, or have a system to wait for Goldfinger? Why do I travel to Dragon Ball and become an earthling? There is no Goldfinger. Give me a Saiyan, not even a frozen demon or a Lamite bloodline. Unfortunately, the wish is beautiful, but the reality is cruel. Let's see how I, an earthling, can turn against the wind and become the pinnacle of Dragon Ball. This novel and its characters are purely fictitious.
