Who is the actual villian? The emperor or the grand princess or Lord Wei

In the novel he is the emperor.
But here some things have changed, some important characters are missing.

Do you remember the episode where he was looking down on the founding emperor saying....'So what if you united the lands and founded the kingdom!?'....It was mostly saying that I have been in power so long, have kept the balance, defeated all my enemies and now

 "I WILL DO SOMETHING NO EMPEROR HAS EVER DONE BEFORE!!!" - His words

 soonsetra:

Immortality of course. When one taste power, they want to have it all for eternity.

Ah ...ok....the time he was taking in the temple 

Thanks so much 

 Grimmerock:

he needs sacrifices for immortality so kills them using pingyuan

Oh...now i.understand , thanks..... so the princess will suffer when she finds out.....but what does the baby dragon have to do with all this?

Loong dragon seems to favor the royal family because of a special kind of purple qi that only they possess.
the emperor is the foremost powerful in the family so his qi is the strongest, hence emperor was surprised when it threw him off.

So what does it mean for Xu Qi An? How come he was able to subdue the dragon? Does Xu Qi An have a special identity?
