I can agree only in old age , or like Isekai after death.
I want arcanepotence.
Various new worlds is not bad , especially when your power go beyond any laws and limits.
With that power I can go to any cultivation world , spend few hundred thousand years in practice and state of being cultivation.
Then go fantasy worlds , magic worlds , show them master class.
Go to Warhammer 40k and become another fraction that supernaturaly superior but live in material world.
Most fun thing is warp energy is fuel for my instruments, just throw ball and catch demonic Pokemons for our warp reactors.
If someone want to fight I can create planet size death star with anti psychic capabilities and send it to warp for free hunting.
Or go to terra and help transform warp beacon into anti psychic quasar that randomly shot anti psionic rays.
I give necrons living body that consists of black stone but not carbon.
