Set in the early autumn of the 2030s, a struggling salesman finds himself thrust into a dangerous situation after a lightning strike renders him unconscious. When he awakens, he discovers a small fairy-like creature named Yiling communicating with him through a mysterious electronic watch on his hand.

Yiling reveals that she saved his life and warns him of an imminent threat. Earth has become the next target of a necromancer and its zombie virus, a devastating force that has already plagued her home planet. To help him navigate the impending apocalypse, Yiling provides him with a survival manual stored in his watch. Filled with crucial information on different types of zombies, essential equipment, and strategies for staying alive, the manual feels eerily reminiscent of a video game guide.

Despite feeling ill-prepared for the challenges ahead, the protagonist makes a firm decision to take action. Improvising weapons from everyday objects, he forges a wooden spear and a makeshift hammer, arming himself against the undead.

With Yiling's guidance, he creates basic armor from a cardboard box and tape, determined to survive and protect himself in this new reality.

Armed with his makeshift equipment and fueled by his determination, the protagonist steps out of his room, ready to confront a world infested with zombies. His journey is a test of strength, resourcefulness, and resilience as he fights off the undead, scours for vital resources, and uncovers his hidden role in this apocalyptic landscape.

Follow the protagonist's journey as he confronts the undead, navigates the challenges of a post-apocalyptic world, and unravels the mysteries of his newfound destiny.
