This way, even if Xiao Shi was not sincerely loyal to the Great Wu Empire, as long as his people and domain were in the Great Wu Empire, it would definitely bring a huge increase to the Great Wu Empire.
Although this would not pose any threat to Xiao Shi's life, as long as he entered the Imperial Domain, then he would be controlled by the prince for the rest of his life. And if he did not comply, the prince would definitely kill Xiang Zizhen and the people from the Red Tiger Sect.
Xiao Shi had already verified this through the Heavenly Mystery Disc's warning. The prince would definitely not use this to threaten him for a long time. If Xiao Shi refused now, the prince would immediately kill Xiang Zizhen. After all, the Imperial Prince hated Xiang Zizhen to begin with. It was such a rare opportunity, so he would definitely not let him live.
