When Arthur left Master Ronin's place, he headed toward a restaurant instead of going home. It was a high-class restaurant, but he could afford it with his current wealth.
On a side note, it was a lot. He had already procured a million dollars from selling his artifacts. Each of his Protection Armors was sold for thirty thousand. While his Fire-Swords were sold for fifty thousand. His ability was a money-printing machine. However, he had stopped selling the artifacts since he didn't want the market to overflow with them.
However, their life remained the same except for their grocery and outfits. Arthur made sure his clothes weren't extravagant, yet not shabby. He wore a plain grey t-shirt and blue jeans most of the time. Arthur had to explain that they couldn't pay their debt yet or move to a better house before they were able to understand what happened to his father. His mom and brother agreed.
