Nine Heavens Immortal Emperor stood atop the head of the Nine Heavens Cyan Bird, his gaze sweeping across the sea of clouds, which tightened Gu An's heart and made him constantly ready to teleport back.
Each teleportation needed one-hundred-billion-year life span, making it two-hundred-billion-year life span for a round trip; naturally, Gu An was reluctant to return lightly.
The Nine Heavens Immortal Emperor had not discovered the Life Span Barrier; the Nine Heavens Cyan Bird was also unaware.
After a while, a slightly childish female voice rang out:
"Your Majesty, are you truly not going to the Grand Assembly of Ten Thousand Immortals?"
Gu An could feel that this voice originated from the Nine Heavens Cyan Bird, even though the Cyan Bird had not spoken.
