"Old friend, this youngster is interesting," Ziying appraised Gu Tao. "Where did you learn about this?"
Where else could it be but from Xiuling himself? Gu Tao had just mentioned the Sky Tribulation here to Xiuling, and he immediately told him to prepare to welcome the Three Saints of Kunlun. Gu Tao asked what the Three Saints were, and Xiuling told him they were the three revered elders of Kunlun, detached from worldly affairs and solely devoted to the pursuit of the Tao. The moment the Ninefold Heavenly Tribulation appeared, they were sure to come over to take a look, especially since Ai had succeeded in transcending the tribulation. They definitely wouldn't be able to resist.
