Dungeon Master in the Doomsday Wasteland

[Rebirth at the end of the world, Zeng Yi awakens the dungeon manufacturing system! When the wasteland world where civilization collapsed overlapped with the cracks in the other world, a golden data link appeared in his palm: "Can the F-class maze trap the mutant beasts, and the S-class killing array can crush the mecha army?" Facing the federal chaebol's genetically modified human army and the dark magician group of otherworld travellers, Zeng Yi stood under the radiation cloud and sneered. Use zombie lairs to harvest crystal core energy, use mechanical labyrinths to select super warriors, and when the SSS-level [Abyss Corridor] traps gods from other worlds, the global live broadcast lights up with a bloody countdown - "Welcome to my realm of rules!" He and his iron-blooded brother Guo Yu take charge of god-level infrastructure, and use heaven-defying dungeons to rewrite the end of mankind! Upgrade flow + crushing game, see how the strongest city lord on the surface controls the wasteland with a million mazes!
