Technological Beast Control: I Raised a World-Destroying Beast in the Wasteland

[Technological Wasteland + Beast Control + System] After the genetic disaster, the world became a radioactive wasteland. The federation has a monopoly on crystalline energy and treats survivors in contaminated areas as "gene criminals" to be hunted and killed arbitrarily. Lin Shen's sister was listed as the number one target because of her "pure genes". When he was about to die, he awakened the evolutionary system of all things, and the wasteland slime monster he picked up was able to swallow all evolutions! Swallow the mechanical debris to unlock the torrent of liquid metal; swallow the mutant beast core to gain the ability to genetically assimilate; swallow the star gate fragments to evolve a mechanical dragon frozen in time and space! The black crystals hide the shadows of the universe, and the rusty murals hide the secrets of the star gate. When the federal mechas trampled the Dawn Base, and when the void monster tore apart the dimension, Lin Shen stroked the roaring beast of destruction in his palm: "If you dare to touch everything I protect, I will let you see the real doomsday!"
