Adrian aimed the arrows at one of the warriors below and it seems to be a player. Although the player is a high level one, he cannot easily dodge arrows that are as fast as light with ease. He also needs to be against the Desert Sun Beetles as their bodies can explode in an exploding inferno when provoked.
The player thought that Adrian is actually going to kill him even though he does not know what grudge a famous player has against him. He just prayed that he would die immediately and not experience a worse death like what normally occurs in the western continent. The arrow did not hit the player though as it hit the sand beneath him.
The moment the arrow hit the sand, a hideous monster suddenly came out and screeched in agony. The monster looks like a faceless humanoid with only an upper half. It only has a mouth that is filled with numerous rows of teeth and used its two appendages as means on moving through the sand.
