Interdimensional System
What would you do with a system where you can freely traverse into any dimensional world, and take back whatever you gain there?
Scenario details
It's been days Leiden gained a system unknowingly, a system where he can traverse to any work of art world, either anime, movie or anything. Whatever you get in that world can also be taken back to the real world, aren't there many apocalyptic worlds where gold is worthless? He can get them to get rich, and there are also many worlds with advanced tech or supernatural abilities. But as an ordinary human, traversing to those worlds won't be easy, but luckily the system gave him a way out, which is to level up to increase his stats, or buy things from the system shop. But to level up and gain currency, there are only 3 ways: killing (and the other 2 need to be made up yourself because of app censorship), the stronger and more important they are, the better the rewards.
The main world is just an ordinary world in 2016, and the other worlds are all based on the shows or novels, both from anime, movies, comics, and any other works of art.
The MC wants to change his life, who's only an average wage earner which is barely enough for his necessities, because despite his extremely good looks and smart head, the MC was a foreign orphan, which makes it difficult to get better pay because of his background.
