The Elder of Passing Skills had long cultivated the Heavenly Eye, and when Lu Yang performed the water-dividing skill for the second time, he finally figured out the principle behind it.
"So, it actually decomposes water into the two gases of Light Air and Vital Qi. Typically, this only happens when water is struck by thunder magic. I didn't expect you could achieve the same effect with a magic skill. That's truly incredible."
Among cultivators in the Cultivation World, spells that can alter the structure of matter at the atomic level, such as turning stones into gold, are performed at will. The Elder of Passing Skills had so keen an understanding of atomic composition and categorization that he could turn any random stone into radioactive material.
Neither a First-Grade Golden Core nor a cultivator in the fulfilled Nascent Soul Stage feared radioactive materials as their cultivation had reached the state of flawlessness.
