With the Centaur elder's strength, he naturally knew how terrifying a Holy Son was. Even incredibly powerful Empires would have to lower their heads in front of Holy Empires. Their Centaur Kingdom was a mere Royal Kingdom, and it was just like an ant in front of a Holy Empire.
The Centaur elder wanted his descendant to form a connection with someone terrifying like Zhao Fu. This might bring his Kingdom immense opportunities in the future.
Even an Empire could only dream of such a thing, so the Centaur elder definitely would not let go of this opportunity. The reason he was so courteous was not because he was afraid of Zhao Fu but because he wanted to form this connection.
The Centaur Prince looked completely dumbfounded and had never thought that his ancestor would have him, a prestigious Prince, become someone else's servant. He was a Prince! With how proud he was, how could he agree?
