Souta and Yuko left the dungeon where Raeshka lives. The treasures inside that dungeon were something that normal people couldn't imagine. It greatly exceeded the treasury of huge countries like the Hebrei Kingdom and the Eternal Empire.
However, if someone wanted to take all those treasures they would have to face countless first, second, and third evolution monsters. Also, a battalion of fourth evolution monsters with dozens of fifth evolution stage monsters. After that, they would have to face the monster lord, the destruction queen.
If they wanted to clear this dungeon and take all the treasure inside it, they would need a god-level powerhouse in their party. A powerhouse that could match the destruction queen who was famous for her destructive power. An ordinary god-level powerhouse wouldn't stand a chance against Raeshka.
