Why did he come to Jiaozhou? Why did he have to defeat the Jiaozhou Navy? Actually, the origin of all of this was because of the little island on the East Sean, that little island that had been washed with blood.
The pirates on the island were the Ming family's secret army. When the court was investigating rigorously, they had been completely wiped out. Fortunately, a spy of the Overwatch Council managed to survive with difficulty and had reported the bloody scene of that night.
It was the Jiaozhou Navy; it could only be the Jiaozhou Navy. In the months after, the Overwatch Council increased their investigation of Jiaozhou. Although to this day, they still did not have hold of any evidence they could present, the knowledgeable people at the topmost level of the court had determined that the Jiaozhou Navy was the Ming family's hand, the Junshang Conference's hand, and the hand the Eldest Princess nurtured.
