Tianyi Mysterious Abyss

1. Surface World: Tianmai Continent There is abundant spiritual energy, everything is animated, and the civilization of cultivating immortals is at its peak. The three major forces maintain a fragile balance: Taixu Immortal Alliance: The leader of the righteous path, composed of the nine heavenly sects. They are the guardians of order and the framers of lies. It looks glamorous on the outside, but inside it already has an ancient deal with the Mysterious Abyss. Nether Palace: Occupied in the dark side of the continent. Not purely evil, but extremely sane. They believe that this world is a cage and "ascension" is a scam. They believe in "nothing can be broken without establishing it" and they are always looking for cracks in the foundation of the world. Xingjian Tower: Hanging outside the nine heavens, its headquarters is in the Taixu Star Sea. The disciples are all prophets who are born with different eyes and can capture fragments of time. They are not involved in disputes, but every time they appear, it means that history has reached an irreversible fork in the road. 2. The inner world: the mysterious abyss The abyss is not a location, but a "reverse causal dimension" associated with the material world. It is composed of "rules" rather than "matter" and is the source of all suspense. Core setting: Mysterious Abyss's "reverse deduction" attribute Any soul search, time retrieval, or celestial deduction for the Mysterious Abyss event will result in contaminated results—either false memories, or direct backlash against the soul of the caster. This means that all the "immortal criminal investigation" methods of high-level monks are ineffective in front of the mysterious abyss. The only things that can penetrate the fog are two things: the "Dao Heart Resonance" associated with the Mysterious Abyss, and the "Original Strange Eyes" of the Seer of the Star View Tower. Therefore, the protagonist group must use "mortal criminal investigation logic" (autopsy, interviews, physical evidence comparison, logical deduction) to fight supernatural weirdness, forming the core tension of "immortal cultivators use mortal wisdom to solve puzzles".
