The second layer of the Demon Refinement Technique is different. For Lin Fei, the Demon Refinement Technique is an unconventional cultivation method. The first layer is completed by refining the body eighty-one times with the Heaven and Earth Qi. However, Lin Fei refined himself more than a hundred times, and his cells were on the verge of exploding because of the excessive Heaven and Earth Qi.
The second layer, on the other hand, is quite the opposite. It involves extracting all the Heaven and Earth Qi from the cells and then ingesting it back into the body, filling every inch of flesh with the Heaven and Earth Qi. Only after repeating this cycle eighty-one times is the second layer considered successfully completed.
