To get the Lightning Sword Domain, Ye Tian Yun subconsciously divided his goals into three stages.
The very first stage that he needed to get to was to convert the pure white dome into a lightning dome.
Ye Tian Yun didn't know what the dome was made of, but in his previous life too, he had reached the step where he got the dome.
Every dome, which we will now call a domain, from any Sword Intent, has very specific characteristics.
For instance, the Fire nature Sword Intent has yellowish-red domains, water nature Sword Intents have blue-green domains, and just like these, the white domain signifies the lightning Sword Domain.
Once a cultivator gets to this stage where he has the domain respective to their Sword Intent, they then focus on getting the domain more in line with the type they are based on.
