It was for that reason Simon had given up on all the other items he had his eyes on and saved his DP. He reckoned that if he truly went all out, with the amount he had with him, he might just be able to get the thing he wants.
That said, the one demon he was truly amazed by, was not the Demon Archdukes but by the guy sitting adjacent to his room. A large portion of the things that were sold, were purchased by him.
The demon that he was talking about was none other than Oswell. The wealth that the latter posses was so great that it made Simon's mind spin. He could even compete with the ancient Demon Archdukes and snatch majority of the things from their hands.
Oswell did tell him that he was very rich; however, he didn't think that it would be to this extent. A demon possessing more wealth than even most of the Demon Archdukes. No wonder, the Demon Lord of Envy was so interested in him.
