This place was nearly two hundred million miles from the Heavenly Chasm. The distance was not short, but if the origin demons possessed special methods, it was only normal for them to discover Fengding Valley's anomaly.
After all, Chen Fei had spent five days investigating the Heavenly Chasm, and the Cold Mountain Domain also had origin demon informants within it. Once some information leaked, it was almost inevitable that the origin demons would begin investigating.
It was even possible that no information had come from the origin demons' informants at all. After the "anomaly" in Yougu City had been destroyed by the Cold Mountain Domain's Heavenly God Realm experts, the origin demons had known that matters concerning the Heavenly Chasm's Demonic Beasts could no longer be concealed.
It was practically inevitable that the Cold Mountain Domain would send people to investigate the Heavenly Chasm. The only difference was what force the Cold Mountain Domain would dispatch and where they would appear.
Chen Fei lowered his head to look at the token in his hand. The token still sensed Fengding Valley, clearly indicating that the Teleportation Formation could still be used.
In this situation, either the origin demons wanted to besiege the stronghold and wait for reinforcements. Cultivators from the Cold Mountain Domain would naturally come to Fengding Valley upon discovering that the token still worked, only to find a group of origin demons waiting here. By then, they would not even have a place to run.
Or these origin demons were still unable to destroy the formation patterns within Fengding Valley, which was why the Teleportation Formation could still function.
Chen Fei swept his gaze around and found no aura of a Twelfth Order Origin Demon. The strongest presence here was only an Eleventh Order Origin Demon at the extreme.
