Souta followed Raeshka with Yuko behind him. He didn't have a mana so he will count on Yuko's mana. He had [Pet Resonance] skill so he could borrow Yuko's mana and her senses. It was a skill of a tamer that could let him combine his and her strength.
If Souta levels up this skill then he would be able to borrow her stats and add it to his own after a certain point.
Even though Yuko's mana pool wasn't large as his it was still enough to cast a few dozen spells.
Souta and Yuko went outside and saw Raeshka standing in front of countless different monsters.
'There are more than a million monsters under Raeshka's rule.' Souta thought as he recalled how her force fought back the demons that invaded this place.
This force was enough to invade a huge country like the Hebrei kingdom. Every army of a monster lord could rival those of a huge country and this was one of the reasons why no one dared to provoke a monster lord.
