The clear sky technique, like the blue sky technique and the yellow sky technique, was a celestial technique unique to the clear sky clan and one of the most powerful celestial techniques.
Unfortunately, the requirements for cultivation were extremely harsh. The requirement for bloodline was extremely high.
Only the blue sky Race and the yellow sky Race could cultivate the blue sky technique and the yellow sky technique. This was the ultimate manifestation of their ancestral bloodline.
No matter how amazing an outsider was, it was difficult for them to cultivate much power.
It was the same for the blue Heaven technique.
Previously, Ye Qing had also passed on the cultivation method of the Azure heaven technique to Lu Ming, Tang Feng, and the others, but they had not succeeded in cultivating it.
