The Prankster.
The minds of everyone went blank after seeing this sight. Whether it was the arrogant youth or the guards, they all became pale with horror. At the same time, they felt a cold chill running down their spines.
Aside from that, they were also bewildered by the sudden gruesome death of the guard.
The old bald monk didn't even move a finger and there were no energy waves, he was still sitting in the same mediative position with his palms placed together.
However, the moment the guard was about to touch him, he suddenly fell on the ground while clutching on his head with his hands before he started crying in pain.
Not even a second later, the guard's head suddenly exploded and turned into a bloody mist with mangles bit and brain matters splashing on the ground.
Furthermore, the guard wasn't weak either. He was a peak Martial Lord. Yet, that weak looking old monk was able to kill him without moving a finger.
