Chapter 73: Superior Crystal Cores
"Sure." Ye Xuan replied and with one hand on the wheel, he used his right hand to get a shiny blue crystal from his pocket.
The crystal was small, the size of a cherry fruit. Even though it was clear and shiny like a diamond, if one looked closely, they could see something dark at the center of the crystal.
Chu Miao scrutinized it and turned it over and over again before noticing the dark patch. It was not very obvious.
She focused her spiritual power in her eyes and observed the crystal, especially the dark blotch.
She could see that it was shaped irregularly, like a floating cloud. She could feel that the crystal core was similar to the demonic beast cores from the ancient cultivation world, but there was a difference.
In the cultivation world, demonic beast cores were filled with spiritual energy and could be used for cultivation.
Chu Miao extended her spiritual sense deep into the crystal core and felt around the dark cloud. She was shocked to find that the dark mass inside was similar to the fog that had brought the changes in humans and mutation of animals.
The rest of the crystal was also energy that can be used to cultivate and enhance superpowers. However, unlike zombies crystal cores, the cores from the mutated rat had an extra type of energy.
One crystal core could be used to cultivate both superpowers and spiritual energy, just like what they did with the fog.
