"So, how do I use a law? Didn't you say that you need immortal qi to be able to use a law?" Li Yao asked.
[Not necessarily. In some cases, you need a law in order to get immortal qi. But that's a story for another day] the Empress said.
[For your case, it's a little different] she began.
"How so?" Li Yao asked.
[You've already been using a law before] the Empress said.
"I have?" Li Yao asked in surprise.
[That's right. Your nine heavens domain, when you use it, you can set restrictions and enforce them through lightning, right?] the Empress asked.
"That's right. But what does this have to do with law?" Li Yao asked, growing impatient as she felt her senior brother being pummeled.
[I was getting there] the Empress said, shaking her head. [Do you know why you have to undergo tribulation after breakthrough? Do you know why you have to ascend after becoming an immortal?] she asked.
"Yeah, it's because of the heavenly dao, right?" Li Yao said.
