The Key to Resonance in the Underworld: I Went Crazy in the Underworld

When the city's neon lights shatter into pieces of dim light at midnight, a forgotten name is whispering deep in the underworld. Qin Yi was just one of the many living beings, until that night he mistakenly entered the last empty subway train and fell into a silent crack. When he returned from the underworld, he had a dark key in his pocket - it could open the spiritual realm, increase spiritual energy, and see through spiritual bodies, but it was also like a fire that burned his soul, pushing him into the center of the storm. Act One: Dilemma. He struggled between the pursuit of the spirit dealers and the erosion of his spirit. Every time he used the key, it was like tearing apart his consciousness with his fingertips. Act 2: The twist. The Gatekeeper Alliance lends a helping hand. He glimpses the truth about the Fallen in the abyss of another world, and begins to understand the price behind power. Act Three: The Price. When he travels through the spiritual realm, amplifies his psychic powers, and gains insight into his opponents, the Netherworld is also watching him, as if waiting for some ancient contract to be awakened. Under the tall buildings, there are corridors where countless spiritual bodies wander; behind the neon lights, there is a battlefield where spiritual powers interweave. And he is using his own body to become the bridge between reality and the nether world, and also the most fragile line of defense. When humans finally touch the edge of death, how can they maintain the bottom line of life?
