In July, the world plunged into an apocalyptic abyss. Extreme disasters and deadly viruses raged, human civilization collapsed, and zombies ran rampant. Guagua, once a travel blogger, struggled to survive after the outbreak in a mysterious RV called the Wandering Home. The RV came with an intelligent System that could detect zombies, purify water, and defend itself automatically. It also concealed an enormous storage space, making it essential to his survival.
On the run, Guagua encountered Lao Zhou, a construction worker; Lin Yue, a nurse; and A Kai, a student, among other survivors. Together, they formed a team and supported one another. They fought off zombie attacks, searched for fuel in abandoned factories, escaped a blizzard, and resolved a water contamination crisis. But dangers lurked everywhere. They had to deal not only with pursuing zombie hordes, but also with threats from unknown forces. The RV key on the roof, which glimmered faintly, seemed to conceal an even greater secret, and more daunting challenges and mysteries awaited them ahead.
