Zombie siege, atop the ruins, Chen Mo opened a 'Safe Zone Convenience Store' - as long as you pay the price, he can use his powers to build an absolutely safe barrier for you. But every time the barrier is opened, his lifespan is shortened by one day. Intelligence dealer Lin Wei broke into the store with a zombie body, claiming to know the secret of his superpower, but asked him to help her find her missing brother. There are laboratory drawings hidden in Lao Zhou's repair shop, Su Wan's medical data points to the symbiotic relationship between viruses and supernatural powers, Zhao Tiezhu of the Tiebei Gang holds the list of survivors, and the mysterious white crow leaves a warning every time he appears: 'The safe zone is not a shelter, but a cage. ' When Chen Mo discovered that his special powers were being used by a certain force, and Lin Wei's younger brother might be that force's experimental subject, he had to make a choice between 'saving others' and 'saving himself'. The safe zone can stop zombies, but it cannot stop people's hearts - when his most trusted allies begin to betray him, how long can Chen Mo's convenience store last?
