Entering the Cave, Blunder (edited)
"That's right. Just behind that hill, there is a cave that leads to the ruins." Livingstone responded.
Henry turned around and looked what the direction that Livingstone was pointing. There, he could see that there was a hill that Livingstone was pointing towards.
But, no matter how he looked at it, that hell looked inconspicuous, looking like there was actually nothing there. But, thinking about Livingstone's words and behavior, it was clear that whatever he was saying was true.
From the fact that there was a group of people that was guarding this area, Henry was sure that there was something here. Otherwise, why would Livingstone bring a group of people here?
Moreover, the behavior of the monsters here was kind of strange considering that they did not approach this area, making sure that they kept a safe distance of about 1 km radius from this area.
