A bad resources harvester
The auction house was held every now and then. But it has been a long time since the last one. In fact, it has been two years since the academy's auction hadn't been held.
Time had been difficult after the last invasion from the alien monsters, so it was hard to hold it.
But now that things had calmed down a little bit and began to flow again normally, the academy decided to hold the auction house again.
But it wasn't only for the students, it was for the entirety of Politia. Though, since it was the academy that held it, there were a lot of students that were participating.
And the auction was so popular because they were selling all kinds of things.
Rare equipment, rare resources, or even rare object with special effects. There were a lot of things. But obviously, there weren't slaves. It was considered something inhuman, so it wasn't a place like an academy that would sell them.
