I'm Building Gundam in Warhammer

Linn always thought that the setting of Warhammer 40K was just to sell plastic villains. Until that golden yellow man (Emperor) really hacked him into this galaxy. In a world where even boltguns have molding lines and the gilding of icons is peeling off, Lynn despairs. Until he discovered that in this universe full of fanaticism and corruption, his "Jiao Lao Skill" was simply a god-level plug-in. ——The bolter jammed? That means the recoil spring is too preloaded, just loosen it half a turn. ——Power armor defense is full? It is a whole piece of casting, and the hydraulic pipe is welded after the knee joint is made, and it is accurate every time. ——The Rogue Trader gave the order crookedly? That's because the gasket is not placed flat, and the gemstone has absorbed half of the stress and will collapse sooner or later! While others were praying for the emperor's blessing, Linn was repairing the gun mechanism with etching needles. While others were chanting the sacred numbers of the Mechanicum, Lynn was caulking the power sword. "Don't mention Ohm Messiah to me. In my eyes, you are all just boards without water openings!"
