Qinnanyuan Code No. 127001

During the final week, during night training at the South District Sports Ground, someone suddenly fell ill. Ten minutes later, the dormitory building began to lose power. Half an hour later, the entire campus's PA system would repeat the wrong command. An hour later, Lanjiang University Yunqi Campus completely lost order. Xu Ze'an, a sophomore majoring in network security, is a class leader. When everyone was escaping to the dormitory, the first thing he saw was not the group of corpses, but the abnormally disconnected surveillance, the access control that was triggered repeatedly, the error return of the broadcast link, and the light in the Life Sciences Museum that never went out. Qinnanyuan became the first isolated island. Relying on a laptop, the remaining campus LAN, and three roommates with different tempers, Xu Zhe'an must defend a building, defend a line, and defend the last thing that can be called "order" on this campus amidst the hordes of corpses, power outages, false news, and the collapse of people's hearts. But he soon discovered that what was really scary might not be the infected people rushing towards him. It's the address that only loops back locally but can no longer be connected to the outside world. ——127.0.0.1
