Xiao Jin, the leader of the Demon Cult, has lived incognito for ten years and transformed into the blacksmith "Pei Laosan". He quenched poison and forged a magic weapon for Song Yulin, the son of his enemy, and made corrosive tea sets for Song Tianxiong, the leader of the alliance. At the martial arts conference, Song Yulin slashed at the leader of the Demon Cult with the "soul-breaking" knife that was specially designed to defeat demons. The blade suddenly shattered - what was exposed under the hood was Pei Laosan's cold face: "What the leader of the Demon Cult is best at is forging iron."
