Dudian was slightly surprised.
At this time, this rocky surface stretched out and two sharp teeth came to his view. It didn't stop for a moment as it bashed over towards Dudian.
Dudian understood that the surface which he had stabbed earlier was cuticle of a rock monster. He raised his hand and punched over to the position which Dudian considered as the monsters head.
Bang! His left hand had hit the monster. It was affected by the hit as it hurried back for a moment.
However, it screamed as it was impinged by the hit and rushed towards Dudian in anger.
Dudian quickly grabbed the knife in his hand and stabbed it.
The knife stabbed on its scales but did not cause the slightest injury. Although the knife was used by him less than a week but had been worn down seriously. It wouldn't be able to cut through the skin of an ordinary person.
Swinging its head the monster attacked Dudian's left arm and bit on it. Though there was no pain.
