บท 163: 2nd Last Floor

"So this is the fourth floor." Ariel muttered 

The four had already picked up the magic stone on the third floor after washing it with water before descending down the stairs. 

They were in a cave like hall with red molten lava flowing down the holes on the sides. 

At the end of the cave stood a large door which most likely led to the boss room. The cave itself was completely lit up by all the fire and lava 

"It's hot..." Serena muttered 

If not for the fact that John was using both wind and thermal manipulation magic, they would've been sweating bricks. 

"Let's go... Just 1 more floor after this." John muttered as he began heading towards the door 

As the four walked towards the door, they noticed that something was strange 

"Hey... Shouldn't we be getting attacked by monsters by now?" Serena asked 

"I was thinking the same thing... It's too empty." 

"Yeah, I can't detect any monsters around with deprehended either."
