The Given Alliance is the only alliance in the Nine Serenities Battlefield with two leaders. This was to accommodate Wu Long.
Ji Ying, the Leader of the Given Alliance, doted on Wu Long so he naturally agreed to make Wu Long the second Leader of the Given Alliance. This fact was widely known by the high-ranking members of the alliance. Since they were all members of the same alliance, it was inevitable that this would come up during conversations.
"Perhaps, Duan Ling Tian's really unaware that Wu Long is the second true disciple of the Heavenly Emperor of the Given Heaven…"
An elder of the alliance shook his head and said, "Impossible. Leader Wu Long would definitely reveal his identity when he challenged Duan Ling Tian. Moreover, even if Duan Ling Tian was initially unaware, there's no way no one from the Heavenly Dao Alliance didn't recognize Leader Wu Long. His identity aside, he's widely known for being the strongest Eight Star God of Star in the Nine Serenities Battlefield."
