The Rock Monarch's face changed nonstop under Qingfeng's threats, because in the previous clash, he realized that his power wasn't the same as this youth's.
The Rock Monarch looked at Qingfeng before him and said, "You can't expect me to hand over the Heart of the Saint Rock, it's impossible."
The Rock Monarch's power came from the Heart of the Saint Rock, and once he loses it, then he wouldn't have any power and wouldn't be able to control the rock men tribe again. He would turn back into a normal piece of rock, so he wouldn't hand over the source of his power.
Qingfeng froze and then said, "Since you won't give up the Heart of the Saint Rock, then don't blame me for showing no mercy."
He stepped forward by one step, and the ground beneath suddenly cracked, as the ground wasn't able to contain the power of Qingfeng's body.
