In order to prove the value of mechanism art, Ye Qingyu took the "scrap iron" puppet discarded by the sect to participate in the weapon refining ceremony, but was slandered as an "evil heretic". He backhandedly dismantled the immortal weapon of the Zhenpai and used the parts to assemble a "funny puppet" that could talk in cross talk, which shocked the Immortal Alliance.
In order to find his missing father, he went deep into the Shiwan Mountains and used the machine beast to fight against the demon clan. As a result, he was mistaken for the "Mechanical Demon Saint". When cooperating with Bai Li, the demon princess of the arrogant Phoenix bloodline, he accidentally activated the remnant soul of Yanshi in the core of the puppet and unlocked the "perpetual motion pattern".
Tianji Pavilion predicted that "the mechanism will destroy the Tao", and Ye Qingyu was forced to get involved in the thousand-year grudge between the world of cultivation and the Weapon Refining Sect. The "Gun Taotie" he transformed swallowed up the spiritual veins of the Immortal Alliance, used steam puppets to break through the Nine Heavenly Palaces, and finally refined the "Entropy Talisman" in the refining cauldron, plunging the eternal laws of the Immortal World into chaos.
