After Zhou Feng discovered that the conflict in his body could repeatedly trigger Old Skin, he crazily harmed himself and forcibly operated the Demon-Devouring Technique.
He wanted to fuse all the chaotic Qi within him.
The result of doing so was naturally that his meridians were damaged, his body was riddled with holes, and countless injuries appeared.
When the damage was almost enough, he began to heal his injuries.
He used the passive Self-Healing Constitution and some pills to assist him. He allowed his injuries to recover slowly, thus triggering the passive Old Skin.
"The recovery speed is still not fast enough!"
Zhou Feng was somewhat dissatisfied with the recovery speed of his injuries.
The passive support of the Self-Healing Constitution, coupled with the Demon-Devouring Technique itself, could speed up the recovery of his injuries.
