My Basement Leads to the Underworld

Seventeen-year-old Lin Mo moved into the old house left by his deceased grandfather. There is an iron door in the basement, which is only open from midnight to four in the morning. Four rules written in blood were engraved on the iron door, and a black mark appeared on the palm—— He is the last "border guardian" of the Lin family. The underworld behind the door is not the underworld mentioned in Buddhist scriptures, but a parallel dimension constructed by human collective consciousness. The six levels of areas are in-depth: Border, Mist City, Forgotten River, Judgment Stand, Abyss, and Guixu. On every floor, there are people waiting for a living person to arrive. Someone wants to devour him. Someone is taking advantage of him. There is only a half-soul girl named "Xiao Qi" who wants him to live. But the price of living is this: the deeper you go, the closer you get to an ancient truth. The two realms of Yin and Yang were once one. What splits them is a "nucleus of consciousness" sleeping deep in Guixu. But now, the seal is being destroyed artificially. When Lin Mo finally stood in front of the core of Guixu, the being only asked one sentence: "Are you going to seal me off or become me?" ——He chose the third way. But he forgot that people who choose to become a "higher existence" often lose "themselves" first. On the day the iron door closed, Lin Mo returned to his sophomore class. He thought he had won. Until the girl at the same table handed over a note: "Your grandfather was not the first guardian. There is something beyond Guixu." This world is much bigger than he thought.
