"Come in!"

The ethereal voice of the old Celestial Master reached Daoist Xuanzhenzi's ears. As Xuanzhenzi entered, he saw an old man with black hair, a rosy complexion, and skin as smooth as a baby's. The old man appeared to be only fifty or sixty years old, but Xuanzhenzi knew that the Celestial Master was already a hundred years old.

"Old Celestial Master, I have some doubts in my heart, so I came specifically to seek your guidance!"

Xuanzhenzi bowed respectfully.
