"The first purification of spiritual energy, begin!" Zhou Yun chanted in his heart.
At the same time, many methods of purifying spiritual energy flashed through Zhou Yun's mind under the Enlightenment State!
In the end, Zhou Yun classified them into two categories.
The first was to solve the problem. Improving the cultivation technique, directly filtering out the spiritual energy when absorbing the pure spiritual energy, thus achieving the state of spiritual energy purification.
Many cultivators absorbed the mottled spiritual energy, but they didn't have a way to purify it, so it was mottled spiritual energy from the absorption to the use. As time passed, it would even cause one's aptitude to decline.
