The first time Ning Cheng entered the cultivation practice within the rings of time, he already had experience. It wasn't that the deeper he entered, the better it was for cultivation. The deeper into the rings, the longer the time ratio, but the flow of time and Dao Rhyme might not suit him.
On the forty-ninth ring, it meant that he had cultivated here for forty-nine years, while barely a year had passed outside. With the speed of his Xuan Huang formless cultivation, coupled with the help of the Xuan Huang Origin, he believed that in about two hundred years or so, he too could perceive the realm of Dao Elements.
One after another, divine spiritual veins were tossed out by Ning Cheng, but he did not take out that top-grade divine spiritual vein. Inside the rings, the divine spiritual aura was already rich, yet Ning Cheng still felt it wasn't enough. He was well aware of the resources he needed for his cultivation.
