Shatuo... do you still remember Donkey Wang? Luoyang City Was built a thousand years ago. The old city subsided during the Han dynasty. A new city was built on top during the Sui dynasty. The old underground city became a black market. They call it the Phantom Bazaar.

Detective Dee:
Ruling requires power and strategy, but right and wrong cannot be confused.
