He wakes up in another world, having transmigrated into the body of a good-for-nothing with no magic power, despised by everyone? His fiancée breaks off their engagement in public, his rival humiliates him, and his family faces annihilation? Lin Yu smiles. You know nothing about power! No matter. You have magic, and I have Gundam! The 【Heart of the Machine God】 System awakens, bringing a top Earth mecha designer to another world to unleash a storm of steel and flame! Your forbidden magic can destroy the world? Sorry, my phase-shift armor won't even get scratched! You're a mighty dragon, proud and physically invincible? Try a taste of my hundred-meter beam saber. It'll give you a nice trim! You have an unstoppable charge of holy knights? My remote-controlled gun array says everyone is equal under absolute firepower! You're the God of All Magic, who can destroy a city with a snap of your fingers? The electromagnetic sniper cannon is ready. Ever heard the saying, “Everything within range is the truth”? Starting from scratch, collecting scrap metal, and building my very first mecha, 【Pioneer】! Crush all opponents, trample the chosen ones, punch demons, and cleave evil gods with my sword! When a colossal steel deity descends upon this continent of swords and magic… the whole world will tremble before me!
