The remaining pure Yang Qi was stored inside the Purple Crystal.
As the pure Yang Qi was highly compressed, it had now liquefied into golden droplets. It looked like melted gold and it was extremely pure.
Seeing the golden droplets, Yi Yun was extremely delighted. With them, his cultivation level could rapidly increase in a short period of time.
Yi Yun had already been stuck at the early stages of the Yuan foundation realm for quite some time.
Other than the golden droplets, the Purple Crystal contained two other energies.
The first was the pure Yang spirit, which was what Yi Yun had obtained in Fallen Star Gate.
The second was the extremely cold Yin energy. Back when Yi Yun was thrown into a cell by Shen Tu Nantian, Shen Tu Nantian force fed Yi Yun a Seven Noxious Divine Yin Pill.
This Seven Noxious Divine Yin Pill contained an extremely cold Yin energy. If not for the Purple Crystal absorbing and compressing its energy, Yi Yun’s cultivation would have been destroyed.
Thinking about this, a playful smile suffused on Yi Yun’s lips. It was time to visit Young master Nantian. How Shen Tu Nantian treated him back then, it was time to return it to him in the same way!
After absorbing all the pure Yang Qi, Yi Yun was not in a rush to leave. He glanced at the pile of bones left behind by the Red-eyed Wolf and put them away.
With the Purple Crystal’s energy vision, Yi Yun knew that the black evil energy was still hidden amongst the bones.
After carefully examining the black gas, Yi Yun realized that not only did it not have any signs of deterioration after swallowing the Red-eyed Wolf’s vitality and flesh, it had actually grown stronger.
Of course, as the Red-eyed Wolf was too weak, the evil energy did not become that much stronger. However, this discovery alarmed Yi Yun.
What was this evil energy? It seemed like it could grow!
It sounded too fantastic and it was extremely creepy!
Could it be that this evil energy could grow indefinitely?
Upon thinking of this, Yi Yun shook his head and rejected the idea. It was unlikely as the Shen Tu family clan probably used primordial true spirit-grade treasures as materials to refine the Great Empress relic.
They would not have been able to find materials more precious that that.
