Death of Endl?

Sylphe was still waiting for the support of other adventurers to return to the cave, but they were taking so long that she was almost coming back alone, even if she died she would do something on her own.

'Why are they taking so long?' Doesn't it make sense that they take so long, isn't Endl a strong and important adventurer? Why aren't they doing their best to go after him?

Sylphe did not want to go up to the guild master to talk to him because it would take more time, but it was taking so long that she was almost doing this, she wanted to scream and cry inside that guild, but she knows it is not good to do that.

The adventurers continued to talk about it, and it made Sylphe even more nervous, they don't stop talking about Endl even when he is killing himself to contain that monsters, these people suck.
