This was what An Kai had planned for the city to look like in the future.
Therefore, he was willing to give Hanks 10% of the tax. This was already a huge concession, given their past friendship.
If it were Sally Buklin or Will Buklin, who had interacted with An Kai before, An Kai would not have given them this 10%.
One was whether the two of them would be able to open up trade between the outer chaos city and the seven countries... An Kai was still doubtful about this.
Although they were the princes and princesses of the Buklin Duchy, they were not the princes and princesses of the seven kingdoms.
On the other hand, Will Buklin was still considered better. Because of the uniqueness of his profession, An Kai still had some trust in him.
Sally Buklin was eliminated from An Kai's mind. An Kai would never cooperate with her for a deal worth millions or tens of millions of gold coins.
