In fact, Duan Ling Tian and Ning Yi Xuan's fight in the single-person realm should not be known at all. However, since the supreme powerhouse of the Ning clan broke the rules of the Realm Battlefield by saving Ning Yi Xuan, he was punished after a meeting between supreme powerhouses was called. The other supreme powerhouses were naturally curious about the matter and enquired about it before telling their descendants about it.
The descendants of the supreme powerhouses were naturally curious about the person who almost killed Ning Yi Xuan. After all, the person was just a rudimentary Supreme God who had yet to stabilize his cultivation base. They quickly investigated the matter, sending their subordinate to various Realms of Gods. It did not take long for them to find out that the person was Duan Ling Tian from the Profound Energy Land's Myriad Laws Academy.
