A god got tired of reading mangas and anime because this god think that humans are comepletely different compared to the ones on the mangas and anime that he knows.
So he conducted several tests and expirements by reincarnating and transmigrating random humans from across the world, to his newly created world that he instantly manipulated its time to many years later where the classic summon the hero troupe time to tests it.
If the hero fails the world will be ended by the demon lord that he created with cheats. And later he finally learned that almost all of them are useless and some only became merchants and built guns using creation magic.
But they are vulnerable and useless against B+ rank monsters and adventurers. As the bullets bounces off, not to mention creating creating nukes against demon lord cannot even scratch him or even just a weak rogue demon from the demon realm.
No matter what these reincarnators and transmigrators do they are not successful against killing the demonlord. So he finally gaved up reincarnating and transmigrating humans the normal way.
So he gave them cheats and honestly it was a success. But that didn't go well many years later, not because the world was filled with reincarnators and transmigrators. With overpowered cheats and defeating the demonlord.
Turns out the reason reincarnators and transmigrators instantly arrive in that world. The world automatically becomes stronger and stronger, and now the more powerful the cheats already making some of them equal to gods, elder gods, and supreme gods in potential.
The world trancends, but why does the world gaining conciousness overtime and blushing when it sees me gaze at it, wait what?
