"Your guess is not wrong, 108 strands of True Qi are not the extreme of the True Qi Realm, in fact, it can only be called Minor Circulation." Mr. Pei Laozhu chuckled: "Above this, the only way to truly reach the extreme of the Qi Realm is to condense a full 360 strands of True Qi, which is called the Great Circulation. And there exists a legend that the Perfect Great Circulation consists of 365 strands of True Qi. Li Tiange was able to condense 360 strands of True Qi, thus stepping into the Gang Qi Realm through the Great Circulation. My guess is that he hasn't stepped into the Perfect Great Circulation."
Given Mr. Pei Laozhu's high regard for Pei Xuanjing, he naturally would not want to waste Xuanjing's talent. He would have brought up some of the secrets of cultivation even if Xuanjing hadn't asked about them.
