The Nangong brothers knew Duan Ling Tian was extremely talented in Martial Dao previously. The fact that he was at the Inner Land showed that his ability was outstanding too.
However, just because his ability was outstanding did not mean that he would be able to handle the black-robed man standing before them.
The black-robed old man was at the Seventh Level Martial Monarch Stage.
Although both of them had some great encounters since arriving at the Inner Land, they were just at the Fifth Level Martial Monarch Stage and Sixth Level Martial Monarch Stage respectively. They were far lacking compared to the black-robed old man.
Let alone the black-robed old man, they even thought Duan Ling Tian's strength was weaker than theirs.
Therefore, they did not want to involve Duan Ling Tian in their matter.
