Howard had no desire to argue with the mentor.
After all, as a mentor, Daniel wouldn't partake in the distribution of any spoils, so it wouldn't affect them.
On the contrary, should there be a high-level BOSS within the Ruins, having Daniel around might actually be a boon!
Realizing this, Howard promptly responded with a smile, "If the mentor wishes to join, why would we students object? The Ruins are related to the legendary vampires, with monsters likely being over level 30!"
"Vampires? Aren't they mythical creatures? They actually exist!" Daniel was equally taken aback, adding, "The Ruins must have been there for quite a while. You all must be cautious! I won't intervene until a monster appears that you can't handle."
