Ancestral Dragon Seal?
The so-called "Imperial Jade Seal," crafted from the He's Bi on the orders of the First Emperor by Prime Minister Li Si. Measuring four inches across, the top knob intertwines five dragons, and the front bears eight seal characters written by Li Si, "Received from heaven, may the longevity be prosperous" as a token of "the divine right of kings and the legitimacy of authority."
Seated in his wheelchair, a young man asked Mr. Su Bai if he had ever seen the Imperial Jade Seal. Mr. Su Bai indeed had seen it, though not with "his own eyes," but through the perspective of a vampire locked in a prisoner's cart. In that scene, Ancestral Dragon had crushed a Black Dragon obstructing the path with the Jade Seal.
"Heh, interesting, very interesting," remarked the young man as he scrutinized Mr. Su Bai again, "That shouldn't be, absolutely shouldn't be."
"Are you sure I have seen it?" Mr. Su Bai asked.
