Ten years passed in the blink of an eye.
Long accustomed to monotony, Chen Lin hardly noticed. Instead, he immersed himself in understanding spells and found the days fulfilling.
During this period, he deepened his mastery of the Nightmare Spell, Stillness.
But he was still far from complete mastery.
All spells grew harder to comprehend the further one progressed, and nightmare spells were especially so.
Nightmare spells were manifestations of the Nightmare Realm's rules, vastly different from conventional spells. Understanding them depended entirely on intuition, so progress naturally could not be fast.
Once Chen Lin felt his progress had become too slow, he stopped and began studying other spells.
This time, he focused on the Transformation Technique.
Innate law origin was a universal energy. It could encompass not only the laws of the Upper Primal Domain, but also the lower-grade energies of the Lower Primal Domain.
In that case, he should be able to use the Transformation Technique as well.
However, using innate power was very different from using ordinary mana. He needed to modify the spell's method of execution to make the two compatible.
