When the city's neon lights shatter into shards of ghostly glow at midnight, a forgotten name whispers from the depths of the Netherworld.
Qin Yi is just one among countless ordinary people, until one night he accidentally boards an empty last train and falls through a silent rift. When he returns from the Netherworld, there's a key in his pocket, glimmering with a dim light. It can open spirit realms, amplify spiritual power, and see through spirits, but it's also like a spark that burns the soul, pushing him toward the heart of the storm.
Act One: Crisis. He struggles to escape spirit traffickers and resist mental erosion. Every use of the key feels like tearing open his own consciousness with his fingertips. Act Two: Turning Point. The Gatekeeper Alliance reaches out to help him. In the depths of an alien abyss, he glimpses the truth about the Fallen, and begins to understand the price of power. Act Three: The Cost. As he travels through spirit realms, amplifies spiritual power, and sees through his enemies, the Netherworld watches him too, as if waiting for some ancient pact to be awakened.
Beneath the skyscrapers lie corridors where countless spirits wander. Behind the neon lights is a battlefield woven from spiritual power. And he, alone, is becoming a bridge between the real world and the Netherworld, as well as its most fragile line of defense.
Now that humanity can finally touch the boundary of death, how can it hold fast to the line that separates life from it?
