583 The Tomb Of The Supreme Ruler (7)

BOOM!!!

An enormous explosion slammed towards the group. Those who had not followed the Murong family's example and raised their defenses were blown away by the explosion. They spat out mouthfuls of blood while some who were of lower cultivation ranks had their arms and limbs severed or blown to pieces from the great impact of the explosion.

Master Murong was shocked into a daze. If it had not been for Gu Ruoyun's warning, I might have ended up sustaining heavy injuries from the blast. 

"Lady Gu... What caused this explosion?"
