Cap 788: Sharks!?

When we came out of the small tunnel, we were in a big tunnel, this place was big enough for a train to pass through here. 

"Be careful, this tunnel was dug by a Desert Worm." (Randel) 

"I'm surprised they go near this town, with so many water rocks around here." (Margareth) 

"This tunnel was dug before the city existed, it is abandoned now, but other monsters try to make these places into nests, criminals also use these tunnels." (Randel) 

"Where are we going?" (Kira) 

"We are towards the underground river and from there we go to the Oasis of da Cachoeira." (Randel) 

"Should take 4 days one-way travel." (Margareth) 

"Does that mean it's 4 days there and 4 days back, can you stay away from the Guild for that long?" (I) 

"Yes, I told you I'm going on vacation so I don't have to deal with the people from the Temple of Blood." (Randel)
