Solving Dragonball Verse:
(mostly taken from fanfics. but some parts I improved)
Dr Gero invented the utter bullshit that is
Eternal Energy Reactor
an infinite Ki reactor that he gave his "androids" (cyborgs) can be
trained to produce even more Ki. Those androids were resurrected by the dragonballs, including creating a brand new body for them with a brand new eternal energy reactor. Thus making it clear that it is within the power of the dragon to create.
bulma has invented dragonball detector.
The Ball Detector is a Dragon Radar designed and built by Bulma used to detect dragon balls. It picks up the faint eletromagnetic resonance within the dragon balls and locates them as blips on a sonar style screen. The Ball Detector's only weakness is that it can't detect balls that have been...

demiplanes are a thing that kami knows how to build
Room of Spirit and Time
and the dragon as a creation of Kami has the ability to do anything Kami can do.
then you have the bullshit that is the
The Tree of Might (神精樹, Shinseijū, lit. "Divine Essence Tree"), nicknamed the "Tree of Death" by King Kai, is a tree that grows the fruit of the Tree of Might. It appears in the movie Dragon Ball Z: The Tree of Might. The origin for the idea of the Tree of Might was from an Asian ginseng that...

which feeds on a world's worth of Ki to create fruits that instantly levelup someone by a massive amount.
So you need to find bulma and either join her and steal the balls at the last moment or convince an impressionable horney teenager to go along with your wish. Possibly by taking turns with wishes and doing several runs.
If doing the taking turns (since there are 3 wishes per summon) you can use your own wish (for example) to be able to sense and detect dragon balls.
Optional wish: get the ability to sense the location of dragonballs. Might be better to slot this after wish 1 but before wish 2.
Wish 1: an eternal energy reactor. optionally try for better integration? maybe make it organic for better integration with regen powers? but do you even need to? a new one was made when they were resurrected by the dragon. And Dr Jiro did make cell so it might have been organic to begin with
Even a regular non improved one will work just fine. It is canon the cyborgs can train to become ridiculously broken if they only bother to. It is also canon that wishes can resurrect the cyborgs in a brand new body with a brand new eternal energy reactor. Thus Shenron can absolutely fulfil this wish as he has already created such reactors in bodies before in canon.
Already after wish 1 you are already broken as hell and super OP. On par with lower end super saiyan with immense potential, but you can always go further. So lets try to seize more power.
Wish 2: teleport all tree of might fruit and seeds in the local universe to you (dragonball is a multiverse. you don't want to try reaching beyond the local universe as you would alarm some deities. might also exceed the power of the dragon). Canon wishes were able to instantly transmit people between planets. So it can definitely canonically teleport at least 1 seed to you from anywhere in the local universe.
Wish 3: a demiplane under your control and anchored to yourself, powered by your eternal energy reactor where you could plant the tree of might seeds. The creator of Shenron (who is being tapped for magic knowledge for it) is the namekian Kami of earth. He is also the creator of the chamber of time and space, a demiplane with different timeflow rate used for training. Thus canonically he is able to fulfil such a wish.
and bam. you now have infinite supply of tree of might fruits. enjoy not having to even bother training. If it doesn't work you would have to make due with actual training using the infinite energy reactor. So sad.
Wish 4: Teleport you to the Yardat planet. so you can learn instant transmission from the people of that world.
