Dimension Hopping!

Chen Mo awakens a forced time-travel ability and falls into a zombie apocalypse. To survive, he risks his life to seek national aid, summoning the most elite special forces and research teams. Together, they explore the other world, discover zombie weaknesses, crush the zombie tide with overwhelming firepower, and pacify wasteland survivors with food and order. After gaining control of the teleportation portal, the Three Heavy Brigades of Great Xia embark on an expedition to the other world to establish a base. The collision and fusion of wisdom and resources from both worlds successfully activate the super mecha Rezer, sweeping through insect swarms in the dire situation. To achieve total victory, modern Great Xia mobilizes the entire nation, openly conducting physical exams while secretly screening warriors, and counters foreign blockades with a nuclear fusion trump card, launching a full-scale savior battle across time and space.
