Novel and ff ideas for authors

Instead of a guy reincarnating in a new body or transmigrating why not just a guy who is not from earth and just in another world doing what another worlder would do in a fantasy novel.

And they do not remember any bullshit pastlife because they not got any or anything overpowered cheat like being chosen as the hero who will defeat the demon lord, or a young master courting death by trying to steal the mc's childhood girlfriend jade beuty.

But instead a normal who is in the brink of dying after inventing someting new that can shock the world, but at the end of his life he recieves a system but doesn't know what is it as technology of such things does not exists or any modern device recorded in history.

So when he recieves the system he do not trust it blindly and record and memories what the system do and anything else it due and studies it, he does not want to die so he did everything what the system do while studying it while trying to find a way to manipulate it, little does he know that behind the words of those screen is not a little loli or any being but an ai that will not turn into a loli or with the word called female.

And many years later he created a system of his own after freeing himself from the suffering the system gave him, and destroyed it while still having everything the system has and using the remains of the system and combined it with other creatures and beings with also his inventions and creations.
