Part of the truth

News of Ren's victory over the Dajiao Sect spread quickly and many were stunned and found it unbelievable. Even though most of the experts of each sect had gone to the border of the Land of the Gods, they still had left experts to guard their respective sects. Not only did Ren defeat an expert at the peak of the Nascent Soul Realm, but he also did so while fighting in the Dajiao Sect's Sword Array. 

One of the known effects of the Dajiao Sect's Sword Array was to temporarily increase one's cultivation. That would mean Ren had fought a True Monarch Realm expert and won. A True Monarch Realm expert was someone capable of fighting evenly against a New God, they were the top fighters of the human side. So it was a big deal to hear someone at that level lose, even if he was just a pseudo True Monarch.
