Nah, it's a heavenly dragon meant to help that monk on his quest. The "extra" is basically them going on the "Journey to the West," which is the ancient Chinese novel this manga is based on! Go check out this YouTube series, a lot of things about this manga make more sense and are funny when you know the characters:

(seriously, the whole "monk gets constantly kidnapped cuz he's delicious" thing is legit, and the fact that the mangaka makes him look "cool" is definitely a joke, lol ;p)
Ohh okok thanks for the explanation, dude :D
Lol, no problem ;)
Wait wait did the jade dragon turn into a horse or some other animal at the end?
