The one knocking on Baiyu's door was Miss Butterfly. As a member of the attendant guard, she was dressed in neatly polished silver armor, standing at Baiyu's doorstep: "Mr. Bai Feng, today is the day for classes."
As for what class it was.
It was naturally the special course on "Manipulation and Understanding of Golden Blood."
Today's lesson was once again taught by Lilith, as for the City Lord of the Great City, not even a shadow of him was seen. Everyone hoped the City Lord would give a lecture, but so far, not even a shadow of him has been seen.
Which is quite normal, maintaining the operations of such a large city, the City Lord of the Great City has unimaginable daily burdens.
After the class ended, Baiyu's understanding of Golden Blood had increased slightly.
But that was all it did.
