Doomsday Star Plunder

In the future world, the land where humans live is already riddled with holes. After the alien war, the earth's resources were plundered and even turned into a colony. That mysterious advanced civilization sent various alien species to the earth and conducted experiments. In order to survive, high walls were erected and became a refuge for civilians. An army of humans formed a defense line on the outside to fight against species. Underground creatures? Even the Titans came out? Chen Zhuo, who originally lived in a small town, had to shoulder the mission of carrying a gun and going to the front line.
