Ability Increase in a Certain Science

[Do not dismantle the CP] [Half sand sculpture and half plot] Su Yan accidentally traveled to the world of a certain scientific electromagnetic gun because he stayed up all night to catch up. Now that he has become Saten's neighbor, and he is also an incompetent person, it is not a big problem. He has a system, but this system seems a bit superficial. It only gives him a seemingly useless ability - ability increase. Let's see how Su Yan develops his own power in the electromagnetic gun and breaks the darkness of Academy City. Ps: The heroine is tentatively named Saten Ruiko, she may be added later. The big world is a world of super guns, focusing on science. The characters in this novel are purely fictitious.
