The world-weary Chen Mo is trapped in the never-ending death subway cycle. After hundreds of tragic deaths, he only longs for eternal peace. Until the girl named Lin tide broke in, she tried in vain to save strangers who reset each time, and was ridiculed by Chen Mo as the "ridiculous Virgin". When the strongest monster arrived and Chen Mo calculated that the only way to survive was to sacrifice her, he found that he could no longer stand by indifferently. This time, he chose to hold her hand tightly and ignite the fire in his heart that had long been extinguished. Because the real salvation may not be escaping from this hell train, but finally learning to live for someone at the end of the cycle.
