When martial artists broke through a major realm, that was when they were closest to the Heavenly Dao, and it was also the easiest time to comprehend the Dao.
Coldfeather had the foundation of spatial laws and his comprehension ability was not poor either.
Hence, Ye Yuan set up an inheritance space anew, making it more suited for Coldfeather. It was all to help him achieve a breakthrough in spatial laws.
And Coldfeather did not disappoint Ye Yuan's expectations either. When breaking through, he finally grasped first-layered heaven spatial laws in one stroke.
In normal situation, even if having another few tens of thousands of years, he also might not be able to completely comprehend it.
Ye Yuan integrated the power of chaos into the Supreme Jade Void Pill. To begin with, it was extraordinary.
Coupled with Ye Yuan's ataraxia and tranquil heart, that was how it helped Coldfeather successfully to brak through.
