Chu Hao first practiced the Sliding Step.
This required an extremely fine grasp of the surrounding airflow, followed by using Star Force to minimize friction as much as possible, in order to increase his speed.
After half an hour, Chu Hao had to stop.
His Star Force was exhausted.
He extravagantly used Star Stones to recover his strength—although Star Force could actually recover slowly except in combat, Chu Hao, eager to master the Sky Stepping Technique as quickly as possible, didn't care about that.
What's more, he was now so poor that he had nothing left but Star Stones.
The next day, he still practiced the Earth Flame Jue in the morning, while the afternoon and evening were devoted to practicing the Sky Stepping Technique, making rapid progress.
