The Title of Domain Lord?

At the base of the Seven Stars Stele, Xia Fei's party was invited into the headquarters of the Devil Shadow Dragoons.

Compared to the former glory of the Fiend Race, the current Devil Shadow Dragoon headquarters was very crude, though it remained as complicated and intricate as ever. Numerous star maps and coordinates were hung up on the walls. The famed tacticians of the Devil Shadow Dragoons planned out their war against the dragons here.

A fang was hanging up on the wall, which drew a lot of interest from Xia Fei. This fang was extremely sharp and took up an entire wall. Xia Fei couldn't help but stare at it.

"That is a dragon fang! Our brothers extracted it from a Megadragon. Before killing a Megadragon, we will pull out one of their fangs! You're only looking at one of them," Raksha said grimly, his hands held behind his back.

A dragon's fang!
