I, the Mechanical God Emperor, Defeat Everything

Traveling through Island, I actually awakened the F-level loser profession [Mechanic]! In this desperate world where humans are shrinking into huge cities and monsters are rampant outside the city, everyone is eager to awaken to the fighting profession. Lin Feng, the world's top weapons expert, has become a useless mechanic who is ridiculed by the whole city - build some iron bulls and Trojans? Can't even defeat a tough beetle! A hellish start? No, it's my paradise! Past life knowledge + [Drawing Assistance System] activated! What elemental mage and berserker? Look at my hands rubbing the earth's technology! Pick up rags and build an automatic ballista "Xiaoqiang", snipe monsters in the first battle, and shock everyone's jaws! Slum warehouse turned into military factory: The drone "Hummingbird" performs high-altitude reconnaissance, and the monsters have nowhere to hide! The machine gun tower "Sentinel" has fire coverage, and the low-level monster tide becomes an experience pack! "Tarantula" combat robot cooperates with partners to defeat the elite behemoth! The torrent of steel sweeps the world! "Nuwa" intelligent core is born, mechanical life has a soul! The "Mammoth" mecha crushed the lord, and the "Dongfeng Express" missiles washed away the ground! The "Kunpeng" space carrier dominates the sky, and the "Pangu" mobile fortress crushes the abyss! When the destructive beasts flooded the city, the former scoffers knelt down and begged for blueprints. Master? Warrior? Beastmaster? In front of my mechanical army - the torrent of steel, the sea of ​​drones, the intelligent armor, and the orbital strike, all give way! From an F-level loser to an SSS-level [Guardian of Civilization], I wield the power of a mechanical god as a mortal! Fire is immortal, steel burns forever! This world dominated by monsters will be redefined by my guns!
