At this time, the Heavenly Maiden Festival is over, and there is no major event in the Goddess Sect that requires Immortal Mei's delay.
Tian Lin was in the Fairy Cave. Although he didn't break through the fourth level, his gains weren't small.
He felt that the Goddess Sect was absolutely not a place to stay long at this time, and he had a mind to leave.
So, though he had cultivated a Vajra Body, and his internal injuries were actually healing on their own, he still acted as if seriously ill, just to make Elder Mei take him away first.
Whether Elder Mei knew Tian Lin's intentions or not was uncertain, but he held Tian Lin with one hand and said to the Sect Master of the Goddess Sect:
"Tian Lin just came out of the Fairy Cave, and his injuries have yet to heal. I plan to take him back to the mountain for a thorough checkup."
