I'm in the Library and I Just Got Hit by a Two-Way Foil.

Lei Yuan: Thank you for the invitation. I am in the library and have just been turned into a two-dimensional creature by a strange object. Fortunately, I was able to get favoritism from Strange Objects. After finally escaping, I discovered another hidden side of the world. The seemingly calm world is actually turbulent. The proud men of all walks of life are holding golden fingers and preparing to show off their talents. Various systems emerge in endlessly. And the forgotten savior changed the world line beyond recognition. Hidden ancient gods secretly corrupt the world. Or the evil heretics are trying to subvert mankind. A shelter organization calling itself the Tower of Babel came to visit. How can I, Leiyuan, be left out of maintaining world peace? What protagonist? What ancient god? What savior? Contain them all.
