A Qiang, a game designer, transmigrates into the Stone Age world of Crazy Builder, the very game he designed himself! Starting with just an axe, he relies entirely on random draws to develop, instantly upgrades buildings, and gains limitless combat power. As the game's creator, he comes with natural lucky charm. His draws land him a cold-blooded special forces soldier as a bodyguard and a gentle, warm-hearted little cook to manage logistics. While everyone else is still eating raw food in the wilderness and fighting over half a steamed bun, A Qiang is already building infrastructure, smelting bronze, and constructing a city with his System Guard. Watch this satisfying comeback story as a max-level human returns to the beginner's village! How will the greatest builder use his overwhelming advantage to construct an iron fortress in the prehistoric wilderness, take on all rival forces, and conquer the world from scratch?
