Is a special technique that allows a person to devour demon spirits to train their soul force at an accelerated rate. It is considered a sinister technique that defies the heaven Dao (way). Nie Li did not want to use this secret technique, since it causes harm to one’s future cultivation. However, when Glory City is facing danger from the Nether Realm's Wugui Family, he felt that he had no choice.
Nie Li has Lu Piao, Du Ze, and the rest of his friends also included in the technique, as there will be more then enough soul force for them all to absorb it. Nie Li stands in the center of the array and transforms into his Fanged Panda.
