The Imperial Dragon Demon Lord stood up from the Bronze Throne, and a pressure emanated from him. Everyone could not help but take a few steps back, their faces changing drastically.
"Is this the power of a Level 15 lord? How is that possible!" Surprise appeared in Qian Xiaohao's eyes. He had only felt such a terrifying aura from those characters above Level 30.
As the Imperial Dragon Demon Lord stood up, he raised his hand. A dragon chant echoed throughout the Underground Palace, and from behind the Bronze Throne, a colossal Bone Dragon over ten meters long slowly revealed its head.
The Bone Dragon's entire body was devoid of flesh, leaving only stark white bones. Two clusters of green flames burned ferociously in its eye sockets. Gray auras surrounded the Bone Dragon, giving people a dangerous feeling just by seeing them.
Qian Xiaohao's face changed, and he shouted softly, "Retreat!"
Instantly, he and the Follower retreated rapidly, heading towards the entrance of the cave.
