Getting a good thing only to lose it soon after

Three people...

The last words pronounced by Yan Tu echoed in the air for what seemed like an eternity as the father and daughter pair stood stupefied.

Lu Xiaoyao might not know the exact level of power that Kang Rong controlled, however, she was naturally aware of the vast amount of forces that her father commanded. Precisely because of this reason, she could have a rough idea of how strong Kang Rong and his faction were. 

Since her father, who loved her more than his own life and cared for her as if she were a baby, had not yet moved against Kang Rong, then Lu Xiaoyao, who was a smart girl, naturally concluded that her father did not have enough power to wipe out the father and son pair under the surname Kang.

Simply put, the power her father controlled was roughly equivalent to that of Kang Rong.
