An ordinary office drone, crushed by a heavy mortgage, exploited by his boss, and ostracized by his colleagues, feels so suffocated by life that he can barely breathe. His fate changes when he picks up an old, battered phone called “Apocalypse.” Cold words on its screen announce that he has entered a supernatural world hidden beneath the modern city. By completing the missions issued by “Apocalypse,” he can earn corresponding supernatural abilities. At first, he thinks it's nonsense, until that very night a monster called the Riftbeast tears through the streets, causing widespread panic and casualties. “Apocalypse” issues its first mission: stop the Riftbeast. The reward: “Incredible Strength.” Lin Yu struggles between fear and conscience, but ultimately chooses to step forward. At the brink of death, his powers awaken, and he successfully drives off the monster. From then on, he sets out on the path to transcendence.
