We walked a lot through the dungeon, almost 4 days of walking counting the breaks and enemies encountered, it happens that the closer we got to the boss of the Dungeon, the more enemies we encountered.
And the enemies were getting more powerful and numerous, as they tried to prevent us from advancing to kill the boss of the Dungeon.
And the boss of the dungeon seems to have noticed that we are going after him, which increased the attacks, but after we got very close, the monsters stopped, the students were relieved.
They thought it was good, but the saint just sighed because she will have a lot more work, the monsters didn't stop because we had greatly reduced their numbers, they stopped because the "Queen" of the swarm is saving her forces.
She realized that she was just wasting troops by sending them carelessly, so she chose that it was smarter to save them to use later.
