Order, Chaos, Creation, Destruction, Illusion, Truth, Seal, Devour, Union, the nine primal runes, and the basic structure of rune inscription.
No matter how advanced a talisman or array formation becomes, the base structure would be created with these nine runes only. Changing them is essentially changing the basic structure of existence.
Since Long Ming's cultivation stagnated at a certain point, he focused his attention to other crafts. His research on the nine primal runes didn't halt at all.
' I have already grasped the power of Illusion and Truth. The Seal rune is also comprehended, but the destruction rune is the hardest.'
Incorporating the power of runes with his own technique was Long Ming's target. Because the nine primal runes aren't just runes; they are laws of the universe.
And once you grasp the law, you will be able to wield it like a natural ability.
