Before leaving, the Supreme Elder of the Wang clan also told Duan Ling Tian that his name was Wang Jing Rao. This could be considered an act of approval and recognition of Duan Ling Tian's strength. If Duan Ling Tian was not strong, it would be impossible for someone like him who was much older than him to be polite or give his name to Duan Ling Tian.
Even in the Wang clan, not many members were familiar with Wang Jing Rao. They only knew of his existence and addressed him respectfully as 'old ancestor' or 'Supreme Elder'.
Following that, before Duan Ling Tian left with Wang Kui, the Clan Leader of the Wang clan, the Grand Elder of the Wang clan also respectfully introduced himself to Duan Ling Tian before leaving.
