From MC's perspective:

Sub-Taboo Hall:

We arrived in the Sub-Taboo Hall. It was daytime. But Carolina was not here.

"Vincent, did you see anyone killing wizard students?" Gilbert asked. His expression says he is contemplating something.

"No, I was all alone in the ruin. I don't even have a map with me to explore the place," I replied with a helpless smile.

It was true. If I had a map, I would have wiped out the remaining Bloodline Hall members.

"Oh, where did you land?" Gilbert asked.

Hearing that I started to tell him. Ignoring the facts about my fights. I told him about those skeletons buried under the ground.

10 minutes later,

"Interesting," A quick gleam flashes in Gilbert's eyes.

"So you found the grave. But there was no treasure in it," Gilbert asked.

I nodded my head at him.

"Then there is only one answer. The items must have been collected by wizards hundreds of years ago," Gilbert said.
