"Hehe, I trust that with Brother Yinhan's talents, you will certainly be able to meet my demands. As for taking away the scroll..." Bi Yan chuckled, and a flash of red light appeared in his hand, revealing a blood-red crystal the size of a fist that he had produced out of thin air.
The crystal was crystal clear, emitting a strange red glow, and it seemed as if countless tiny blood thread-like worms were slowly rotating inside, giving it a somewhat eerie look.
"This is a Blood Oath Mystical Crystal, Brother Bi Yan means..." Liu Ming glanced at the crystal, seemingly without expressing any surprise.
On his journey to Biyou City, Liu Ming had more or less learned a lot about the Netherworld Clan and knew that this Blood Oath Mystical Crystal was an ancient object similar to a blood pact covenant used by the clan.
