Huang Yueli slowly said, "My conditions are very simple. If you wish for me to help then you must completely pledge your allegiance to me! Let's bond via a Blood Pact and swear your loyalty to me, with no duplicity!"
There were many common way of controlling subordinates. For example Li Moying's Shadow Guards actually didn't had too much of a strong binding and it was totally reliant on themselves to swear their loyalty towards Li Moying.
But this kind of relationship required both parties to have a strong sense of trust before it could be formed. Li Moying had grown up with the Shadow Guards since he was young which was why he was able to trust them and not worry about any form of betrayal.
Huang Yueli didn't have that kind of trust towards these practitioners from the small countries.
The reason was because they were originally here for the benefits!
