8,000 meters above sea level
Lifted by the rising air currents, the sound of the wind screamed furiously beside Zhou He's ears as he glided excitedly and apprehensively.
In the beginning, he was somewhat unaccustomed, but after all, he had mastered the Spirit Refinement of Divine Fetal Breathing; his control over his body was extremely strong, and he also remembered every move Lu Yao made while operating the wing-suit.
After several trials, it took less than a minute for him to fly in a proficient manner, nimbly using the power of the air currents.
The Immortal Crane rested for a few minutes and had already regained its strength.
Zhou He sent a message with his mind, "Xueyi, continue to fly upwards!"
The Immortal Crane, clutching the old Taoist's arm, spread its wings and continued to climb. Over three minutes later, they reached an altitude of 10,000 meters.
Below was a world that had become incredibly tiny, with clouds just beside them.
