Cao Brothers were very happy and were planning to kill the left two Horned Bulls and leave the Demon Mountain, however, at this moment, the ground shook heavily and an explosive sound rang out.
It was as of a disaster had occurred inside the Demon Mountain, birds flew everywhere while chirping, animals' roars could be heard, and dust could be seen flying in the air far away.
"What just happened?"
The Cao Brothers and others at the scene were shocked. They looked at the distance and hesitated if they should go there to take a look or leave the Demon Mountain.
At this time, a middle-aged man suddenly appeared in front of the Cao Brothers.
"Third Elder!" Cao Brothers bowed and saluted the third elder. They were not surprised that someone came following them secretly to protect them, after all, they were the young masters of the Cao Family.
