A while later, Ye Qingtang and Master Du witnessed that elderly crush the youth's headless corpse without any change in his expression.
Subsequently, that elderly in a Daoist robe left a ground of blood and walked towards the underground lair.
Before long, explosion sounds blared from within the underground lair.
It was so loud and was as if it could pierce one's eardrums.
This deafening sound persisted for an hour before stopping gradually.
A long time later, the elderly in a Daoist robe walked out from the underground lair with a cold expression. "There's actually a Diamond Boulder blocking the way. How unlucky!"
Master Du smiled at Ye Qingtang after hearing that.
That Diamond Boulder could only be destroyed with an Extraordinary Flame or if the skills of the elderly in a Daoist robe reached the Arcane Supremacy level.
