In Duan Ling Tian's opinion, there was a difference between Ye Chen Feng going to the lower realm and Ye Chen Feng sending his doppelganger to the lower realm.
If Ye Chen Feng sent his doppelganger, the doppelganger would have to bring his prominent divine sword to the lower realm or think of a way to capture Mi Xuan back to the Pure Yang Sect. No matter what, the doppelganger had to return to the Pure Yang Sect and could not be destroyed. Otherwise, Duan Ling Tian might not be able to bring Mi Xuan back to the Pure Yang Sect.
If Ye Chen Feng went to the lower realm with his true body, there would be no problem at all. After all, even if Ye Chen Feng was transported to another Realm of Gods, he would be able to find a way to return to the Pure Yang Sect in the Profound Energy Land.
