About thirty minutes into their journey on the third floor of the Labyrinth, Oliver suddenly shouted out loud, "I see a monster! It's coming from the east!"
Everyone turned their heads simultaneously, and they could see a large fin approaching their direction.
Seeing this, Leo immediately cast Void Spear and tossed it at the monster while it was still in the water.
BOOM!
The explosion caused a slight drizzle, and the monster's guts flew all over the place.

When he saw the notification, Leo knew that he'd killed the monster.
"Hm? We can't collect their mana cores like this, can we?" Leo asked after realizing this.
"That's why most people hate sea monsters, as it's incredibly difficult to collect their mana cores. But there's nothing we can do about it, especially not in this situation." Sarah shook her head.
However, Leo wasn't too saddened by this, as he had a method to collect the mana cores through the Magic System's Auto Loot.
