Demon King's Jade
The Demon King's Jade is the demon-king qualification object contested at the end of the Dark Castle.
History
The sacrifice dispute
When Yoo Joonghyuk tries to take the jade, Yoo Sangah remains mentally active and uses Binding Thread to pull it away. The transfer prevents him from resolving the crisis on his own terms and gives Kim Dokja time to make the decisive sacrificial choice. (Chapter 185)
Abilities and properties
- It functions as a demon-king scenario object whose possession matters to succession and sacrifice. (Chapter 185)
- The corpus passage establishes contested possession, not permanent ownership by Yoo Sangah or Kim Dokja. (Chapter 185)
