Beyond the Three Realms and Six Paths, there is the "Infinite Hell", a place where ancient evil spirits and evil spirits are suppressed. The protagonist Chen Nan, a modern young man, accidentally fell to his death from a building, and his soul mistakenly entered the eighteenth level of hell. Due to his special constitution, he was selected by a thousand-year-old ghost saint and was taught the "Hundred Ghost Slaying" technique. From then on, he began a heaven-defying journey of "killing ghosts, breaking formations, and slaying gods." The story combines hell adventure, immortality and spiritual cultivation, and Eastern mythology, emphasizing the cruel law of "fighting evil with evil, and killing to stop killing"
