In essence, it's about using special Divine Sense as material, and based on one's imagination and knowledge of the laws to create the corresponding runes—just like if your imagination and knowledge reached the level of Sun and Moon, then you could create the sun and moon.
It sounds like a pretty awesome ability.
But in reality, these runes can only exist in an illusory state and require a special array environment to sustain their presence.
Take the Shenyao Heavenly Cave, for example. In that extraordinary heavenly cave, Spirit Plants carrying special runes can grow healthily and exert their bizarre powers on the immortal soil.
After the runes are created, the only way to sustain their existence is through the nourishment and irrigation by the Power of Divine Senses from the cultivators. But if the number increases, it would be extremely troublesome.
