Mr. Zhong's courtesy to Jing Yan was indeed influenced by his own considerations.
Otherwise, given his status, he needed not be so humble towards Jing Yan, a recently advanced martial artist of the Saint Realm.
In the Heavenly Origin Continent, it had indeed been a very long time since a martial artist of the Saint Realm had appeared. But what kind of person was Mr. Zhong? He had been active between the Human Clan and the Divine Race even before the war between the gods and humans.
He did not directly participate in the war between gods and humans, but how could he have maneuvered between the Human Clan and the Divine Race without sufficient ability and strength to earn favors from both sides?
Even now, Mr. Zhong often dealt with powerful figures of the Saint Realm from the Divine Race, and although he was also quite courteous towards those of the Divine Race's Saint Realm, he would definitely not help them for no reason and without seeking anything in return.
