Back in reality, Dongguan sat cross-legged beneath the Kras Tree again.
"Lightforging Battle Art is already outdated. It's unbeatable only against domain-level comprehension. Once laws come into play, problems arise. But Light Refining really is useful."
Dongguan could not help thinking of another secret art manual, Spectrum Analysis.
Since it might contain hidden problems, he had no intention of practicing it for now, but drawing inspiration from it was still a good option.
The principle behind Lightforging Battle Art was to refine light, gaining deeper control over it. This allowed the user to hide within someone else's Light Domain, or even control that domain to strike back at its owner.
But comprehending a law meant grasping a trace of light's essence. Accomplishing the same thing then became extraordinarily difficult. At least, the creator of this manual had never managed it.
That meant that even if Dongguan raised his domain another stage, reaching the ultimate ninefold domain, this secret art would go no further.
Still, that approach of refining continued to captivate Dongguan. Even in his study of the Law of Light, Lightforging Battle Art had helped him no less than Heavenly Blade.

"Maybe Heavenly Blade itself only works with lower laws."
Biluò, the creator of Heavenly Blade, had cultivated the Law of Metal. Although Heavenly Blade was highly versatile, it remained best suited to the Law
