The Yin Water evolved into Gui Water, while the Yang Water evolved into Ren Water.
The Yin Fire evolved into Ding Fire, while the Yang Fire evolved into Bing Fire.
The Yin Earth evolved into Ji Earth, while the Yang Earth evolved into Wu Earth.
This was an evolution of attributes, bringing them closer to the laws of Heaven and Earth.
But that wasn't all. After the ten Golden Cores had evolved further, Yang Hao guided the two Five Elements cycles to converge, harmonizing them with Yin and Yang Power and evolving them into Chaos attributes.
In the end, they evolved into Chaos Metal, Chaos Wood, Chaos Water, Chaos Fire, and Chaos Earth—in other words, the Chaos Five Elements.
This was much like Tang Yuge during the Ultimate Douluo era. She had used the power of the Yin Yang Chaos Bird to evolve the Five Elements attributes of her Kirin Martial Soul into the Chaos Five Elements. With such a successful example to follow, Yang Hao naturally took inspiration from it.
In truth, he had understood and evolved the Chaos Five Elements long ago. Now, he was simply condensing them into Golden Core form.
This step looked easy, but it was actually very difficult, because it required drawing in the Five Elements Laws. Laws were a power that could only be cultivated at the god level, so he had waited until reaching Level 100 before beginning the evolution.
Only Golden Cores infused with the power of laws were true Golden Cores. In his vision, a Golden Core represented eternal imperishability, on par with the gods.
At this stage, the only power capable of lasting forever was the power of laws. So he needed to evolve his Yin Yang Five Elements attributes to their utmost, then bear the power of laws
