The fact that the other party could even know this clearly suggests only one possibility: he was present at the time.
"You... you are the Ear Fox?" Venerable Lin Feng suddenly realized and whispered, "Is this your real form?"
"Real form? Not quite." Cao Zhen looked confidently at Venerable Lin Feng and said, "I also know why you have come to attack me. Considering that you once helped Ju E, I don't want to kill you. So, leave." He didn't want to fight, nor could he admit defeat. Besides, he wasn't wrong; if he really used the Immortal Slayer Flying Knife or the Prosperous Age Picture Record, the one who would die in the end would certainly be Venerable Lin Feng.
Upon realizing that the opponent was the Ear Fox Demon from back then, Venerable Lin Feng decided not to fight. After all, after helping Ju E, she not only received some resources from the Fox Monster Clan but, more importantly, established a connection with them.
