Stopped From Leaving

Back in the cave. 

"Oh crap! It sensed it!" Void exclaimed and headed for the exit of the cave. 

Grey didn't need to ask what Void was speaking about, with his reaction, he knew for a fact that it was a Rank Eight Magical Beast. If the beast meets them here, they would be in danger. 

….

Outside the cave. 

The trio were waiting to attack the beast, seeing Grey rush out of the cave, they looked behind him, but didn't see any beast chasing after him.

"Is it too strong?" One of them asked hurriedly. 

"It's dead, leave immediately. A Rank Eight Beast is coming." Grey warned them. 

When they heard Grey's words, they froze at first. It hadn't even been more than a few minutes since Grey entered, and they didn't even sense any aura of a fight, yet he said he had killed it. 

But they snapped back to reality when they recalled the last part of his statement… A Rank Eight Magical Beast was coming their way.
