Baiting, encirclement
With Huang yize's power, Yun Bilu could do whatever she wanted.
She could arrange it however she wanted to.
However, she had only added herself to Huang yize's team of shadow guards. Nothing else had changed.
She was only doing this to be with Huang yize.
In order to have the ability to protect Huang yize during critical times.
In the end, she would keep her word. She wanted to live and die with Huang yize.
Huang yize had no idea about Yun Bilu's actions.
The shadow guards were trained by him, and they were equivalent to death Warriors. They were absolutely loyal.
Therefore, he trusted her and didn't care if there was one more person.
Of course, the hidden guards were loyal enough to him. Similarly, he had also made them loyal to Yun Bilu previously.
Hence, the hidden guards had to obey Yun Bilu's orders.
