章節 140: Opening a Door In Style

The intricate stone doors in front of the two adventurers just wouldn't budge no matter what. 

"Woo?!" (Shocked!) 

Moon Moon couldn't believe it. They were getting stopped by a door?! How was this even possible? Its master was super strong! 

Jack touched the cold obstacle carefully, following its chicken patterns with its hands, all the way to a jewel embedded in the very middle. It was a dull ruby that didn't show any shine at all. 

"Tch— This is a mana source, and it's totally empty." He sighed.

Moon Moon waved its paw, trying to dislodge it with its claws but without any success. 

"We have to charge it…." Jack explained.

"Woo?!" (Charge it?! With mana?!) 

The two shared a knowing glance. They were utterly tapped out. There it freaking was: the SPI stat check! Without mana, they couldn't use skills nor charge the gem. 

"Woo…." (Would they have to turn back?!)
