Summon Mechanical Soldiers and Build a Doomsday Base

Time freezes to March 7, 2048. It was a desperate day accompanied by a violent typhoon. The zombie virus broke out without warning before, and the whole world fell into chaos. Many people unfortunately died or mutated in this disaster, but there were also some lucky people who awakened their powers, and Li Nan was one of them. He originally thought that having superpowers would give him a chance to survive in this apocalyptic world, but he didn't expect that fate would play a cruel joke on him. During the escape and transfer organized by the remaining members of the school that day, he was betrayed and framed by his dormitory roommate Geng Jun, and was eventually brutally bitten to death by a powerful high-level zombie. Now, the time is turned back to March 1, 2048, and the new semester has only started for two days. Li Nan suddenly felt something strange in his body, and a strong feeling of dizziness came from his head. At this moment, a mysterious voice sounded in his mind: "Congratulations to the host for awakening the mechanical soldier summoning system."
