"Oh my God..."

Before I realized it, Agnes, who had approached me after putting away her aura blade, was just as shocked as I was.

It was understandable.

In front of me, piles of gold coins were stacked up to the point that they looked like a small hill.

I picked up one of the rolling gold coins. It had a strange pattern embossed on it. [ ‘Demon Coin’
Currency used in the Demon Realm. It must be purified using purification skills before it can be used, or it will curse the user.]
Where did all this Demon Realm money come from?

The answer was found in a message left by Tesilid in his notebook. - The place I escaped from seems to be the ‘Pleasure Auction House.’

I was hiding at the time, but I found a glowing map in my inventory. I followed the destination marked on it and found a room with a huge vault. I took as much gold as I could carry from there, but let me know if it’s not enough.
By the way, the item I received as a reward for clearing the fifth trial was the ‘Secret Vault Map of the Auction House Owner.’
