But Demon Queen Bai Keqing was snatched away by his backup identity Ye Fan, and now she has borne him six children, becoming one of his beloved wives.
Even though the Joyous Arhat didn't know Ye Fan was Han Li, he could definitely find out that Demon Queen Bai Keqing wasn't dead. Coming to the Xuan Domain to deal with that matter, he could also take the opportunity to locate both Ye Fan and Bai Keqing.
If a warrior of the Divine Yuan Realm truly wants to search for someone, he has many methods at his disposal, making it very difficult for warriors of the True Martial Realm to defend against. But Grand Elder Han wasn't just any warrior of the True Martial Realm.
Han Li could overlook previous incidents, but if the Joyous Arhat really had such intentions, then he shouldn't blame Han Li for being discourteous. If he found the chance, he would kill the Joyous Arhat.
As for whether the death of the Joyous Arhat would lead to retaliation from Xumi Mountain, that was a certainty.
