Seawolf had plenty of wealth.
Soran had found only about 7,800 Gold Derahls, but all kinds of goods and jewelry were worth 230,000 Gold Derahls. All of this didn't calculate the amount of earnings they got from the black market trading. If someone was sent to take over this, the income there may be more than 50,000 Gold Derahls. Soran once had to work hard to earn some Derahls. The polarization of wealth in this world was more serious than in his previous life.
The tax revenue of this world was almost the same in different regions. Maybe some kingdoms could get millions in taxes, but this must be rich kingdoms like Arendell. In the Ming Dynasty, it was easy to slaughter several wealthy businessmen and powerful merchants and get a year's tax. The world's wealth distribution was not fair at all; there was hardly any fairness to speak of. The money Soran earned by killing two pirates was equivalent to nearly a year's tax of a city.
This money had many uses!
