Xu Changqing sat cross-legged in the air when his brows suddenly rose.
He sensed two streams of Divine Sense probing down from outside Shimmering Jade Grotto.
Had he not been at his peak, with all Six-Element Spiritual Roots complete, he likely would not have detected them.
Moreover, the fluctuations of those two streams of Divine Sense far surpassed those of ordinary cultivators. They were even vastly stronger than any Spirit Transformation Realm cultivator he had ever encountered.
More importantly, Xu Changqing had never come into contact with either of those Divine Senses before.
One male, one female.
The woman's presence was cold and clear as the moon, her Divine Sense carrying an air of lofty solitude.
The man's was fierce and domineering. Wherever his Divine Sense passed, it seemed as though tigers roared and dragons chanted.
This showed just how unfathomable the cultivation of these two was.
With a turn of his thoughts, Xu Changqing roughly guessed the identities of the visitors.
The Heavenly Origin Realm's three great Immortal Sects: the Dragon-Tiger Immortal Sect, the Dongting Immortal Sect, and the Moon-Inviting Immortal Sect.
Among them, Chao Jin, the sect master of the Dongting Immortal Sect, had remained in the Cloudglory Realm all this time and had never shown himself.
As for the other two sects, the Moon-Inviting Immortal Sect and the Dragon-Tiger Immortal Sect, neither of their sect masters was within the Heavenly Origin Realm.
Thus, the only possible powerful figures who could appear at this moment, with such unfamiliar auras and Divine Senses, were Mu Yunyi, sect master of the Moon-Inviting Immortal Sect, and Long Yuan, sect master of the Dragon-Tiger Immortal Sect.
Yet this conclusion made Xu Changqing frown.
By all rights, returning to the Heavenly Origin Realm from the Grand Void Rift required the Guiding Spirit Light
