Ranked Number 1

Amber's bountiful chest heaved in slight excitement. It was like witnessing Cain's miracles could never cease to amaze her.

After all, this seemingly looking lightning barrier was far more special if one inspected their Divine Sense over it. 

Amber recalled studying how domain-type skills are honestly difficult to create and even harder to master. One's control over Divine Qi and their Divine Laws not only has to be high but also at the same level. They need to perfectly fuse the two energies into a bigger energy field that holds a confusing mixture of all various sorts of principles. 

If one can achieve this step, they would successfully form their domain. 

From what Amber remembers, even a weak, self-created domain requires a few dozen or perhaps even hundreds of years of practice! 

Domain Arts from higher realm cultivators practically cost someone to use most of their lifespan just to gain a sliver of understanding.
