Unlimited Modifications at the Beginning, My Robot Girl Became a God

[Mecha apocalypse] + [Good-for-nothing counterattack] + [Pretend to be a pig and eat the tiger] + [Hot-blooded and refreshing article] + [Invincible crushing] I was stabbed in the back by Qingmei at the beginning, my talent was at the bottom of the school, and I was on the verge of being expelled. I activated the god-level modification system. While others were still worrying about drawings and materials, I looked at the scrap materials at the scrap station and fell into deep thought... Adding a giant engine to the mecha, it makes sense for my mecha to have super firepower output, right? Is it normal to install a mirror reflection on the shield and bounce an energy cannon? As for using a vibrating drill to cut through S-class armor, doesn't it just take a hand? When I drove the D-class machine girl stitched with countless "junk" and killed the S-class prodigy's "Ice Phoenix" with one hit, the whole audience went crazy! "Is this an F-level talent? Do you call this a vase machine girl?" "Please stop pretending, you are the reincarnation of the God of Machine!" I, Lin Ye, am an ordinary F-level mechanic. My hobbies are turning waste into treasure and... Making magic machines by hand.
