To sum it up, looking at the four of them now, they were no different from when they were in the Taigu Immortal Path. The only change might be due to understanding Wu Yu had grown substantially stronger and they no longer had the haughty attitude when facing him. 

It was especially so for Prince Le due to Wu Yu becoming Kingmaker Le. This greatly excited him as he felt a little like he had gotten a capable and wise subordinate. 

Qu Yin asked to take his leave after sending Wu Yu over. Prince Le didn't hold him back and simply said, "There are many details to the appointment ceremony that I will need you to brief Wu Yu on in detail, lest he made a mistake and become the butt of the ridicules on the day itself." 

"Rest assured, this is of grave importance to me and I'll ensure adequate preparations for it." 

As such, Qu Yin finally left at ease. Before he left, he reminded Qu Haoyan and Qu Fengyu to serve Prince Le well. 

His son and daughter were on good terms with Prince Le, and it was clear that he would be on Prince Le's side moving forward.
