It's the big boss man of the Bloodline Shrine (The dean if I'm not mistaken)
Qin Chen met him when he went to awaken his bloodline, and it turned out to be the Dean's own bloodline awakening machine, which was very advanced and only people who knew what they're doing could use it to awaken a bloodline (The Dean himself didn't fully know how to use it himself.) Qin Chen did however know, and the Dean respected him immensely as a result.
Hope this helps!
(I apologise if I made any mistakes in terms of details since it has been some time.)
