Core settings
- **Worldview Structure**: The city of the near future is prosperous and glamorous on the surface, but the underground world is divided by three "shadow consortiums". The boundaries between black and white are blurred, and supernatural powers and thermal weapons coexist.
- **Protagonist Profile**: Lu Chen, codenamed "Night Owl", was once a feared top killer in the underground world. After Jinpen washed his hands, he ran a pawn shop on the verge of bankruptcy incognito. He has a cold personality and decisive actions, and has the ability to predict the future for half a second.
- **Core Conflict**: Lu Chen's peaceful life was shattered by the death of his former partner. The only clue left by the other party was a bloody chip engraved with a mysterious totem, which directly pointed to the legendary "Shadow Throne" battle in the underground world. He was forced to return to the world, and he uncovered the mystery of his life experience amidst the murderous moves, from passive survival to active hunting, and finally established his own "Shadow Empire".
- **Power system**: Three major shadow consortiums (the "Golden Power Association" that controls finance, the "Iron Blood Alliance" that controls force, and the "Ghost Eye" that controls intelligence), and the mysterious killer organization "Underworld" that is free from the three parties
