Apocalypse Immunity: The Only Human Zombies Won't Attack

When high schooler Bai Yin wakes up in a parallel world overrun by zombies, he discovers something impossible—the undead completely ignore him. Armed with a mysterious system that grants him a Zombie Companion ability after his first ten kills, Bai becomes humanity's strangest survivor. Desperate to find his adopted sister in the chaos, this loner teams up with Heizi, a scrappy black dog who quickly becomes his only trusted ally. Together they navigate a world where the living are often more dangerous than the dead. In the apocalypse, immunity is power—but trust is the rarest currency of all.
