The acquaintance between Jiufeng and the Celestial Sorrow Demon Monarch was, after all, a coincidence.
Back when Jiufeng left the Mountain and Sea Realm, he made a brief stop in the Celestial Human Realm to search for a world where he could settle his followers.
However, due to the power consumed while traversing through the chaos, Jiufeng was not in his prime when he descended into the Celestial Human Realm.
Then, as in most protagonist templates of novels, the person who was not yet the "Demon Monarch" at that time, the Celestial Sorrow, found the chick-like Jiufeng.
The two helped each other and grew together, with Celestial Sorrow ultimately becoming one of the top powers in the Celestial Human Realm, and Jiufeng gradually recovering his power in the process.
It wasn't until Jiufeng finally left the Celestial Human Realm that Celestial Sorrow took the title of "Demon Monarch" and then chose ascension.
