Shu State was King Shu's fiefdom. In the Great Zhou, a Prince had no military authority beyond a personal Royal Mansion Guard.
But the title of Prince alone was enough to allow them to do as they pleased in their fiefs. As long as they didn't try to raise an army and rebel, the Emperor was extremely lenient with them.
Thus, King Shu wielded considerable power in the Shu Region.
According to Wang Wu's confession, they were Hidden Guards recruited by the Heir of King Shu, and their kidnapping of the "three-yin woman" was on his orders.
The purpose, just as Xie Qingwu had said, was to set up the Taiyin Soul-Inviting Technique. However, Wang Wu had only overheard the name from other Hidden Guards. He didn't know what the technique did, so he had no further information.
