Doomsday Metro: I Drive a Safety Line in the Abandoned City

31 Days before the red fog came, Lin Yan was reborn from death. In his previous life, he had survived in the apocalyptic underground for many years, but was locked out of a ventilation shaft by his trusted teammates and buried in an infected area. In this life, he will no longer trust anyone with his life. When the city was still brightly lit, everyone despised an abandoned subway branch line that was damp, old and losing money, but Lin Yan spent all his money to sign a ten-year right to use it. High temperatures, black rain, red fog, and waves of infected people came one after another, and the order on the ground collapsed. However, the Qingjiang branch line was restarted as the "Ember Safety Line" in his hands. While others were fighting for a mouthful of water, he turned on lights, purified water, stocked up on food, and established rules underground to build his own doomsday subway fortress.
