It was no coincidence that Lin Xuan had been informed about the Heaven-Defying Beast Eye appearing at the auction—it was Yue Xin herself who provided the information. Her ability to connect with him stemmed from one of the privileges of being a regressor: she knew exactly where he would be at any given time. At the moment in question, Lin Xuan had been lingering near a desolate region at the edge of the Abyssal Rift, searching for traces of the Heaven-Defying Beast.
Taking advantage of this knowledge, Yue Xin approached him under the guise of an ordinary traveler seeking self-improvement. Feigning ignorance, she asked what he was looking for, to which Lin Xuan, unconcerned and dismissive, replied that he was tracking something known as the Heaven-Defying Beast. With that opening, Yue Xin cleverly supplied him with the details regarding the beast's eye at the auction.
