Entering Spirit Sea Realm

Duncan met the head of the boar with his sword.

He put all his strength into the blow. The moment the head of the boar met his sword, the impact jarred him. Duncan grit his teeth and exerted more pressure. The boar did the same.

In the end, Duncan was no match for the strength of a Level 2 beast. 

Duncan went flying as the boar shook its head. However, Duncan wasn't completely powerless either. He somersaulted in midair and landed on his feet some distance away and looked at the boar.

The boar snorted angrily and once more charged. Duncan could see a faint line of blood that was trickling on the boar's head. The moment he saw it, the slight trepidation in his heart vanished.

He knew that he could never go head-to-head with the boar after the last clash. That meant he needed to fight smarter here. Duncan's eyes scanned the rushing boar. He could see that the boar was losing a lot of blood at the moment.
