The Nether Dragon Veins were stolen by darkness, and the Three Realms were on the verge of collapse. The god of justice, Yang Jian, suppressed the rampaging dragon soul, but the evil spirit eroded his eyes and transformed him into a demon. The bones of the loyal dog Xiaotian turned into a ferocious white-bone demon dragon.
The "Gu Chen" born in response to the catastrophe is actually a weapon spirit formed by the fragments of the golden cudgel fused with the fighting spirit and the ghostly remnant soul. With the mission of Ksitigarbha to "stop the cry of the dragon", he rushed to the underworld holding the treasure of the East China Sea, the "Essence of Water". Every step he took, the black ice coldness spread across his body and the ice cracked.
In order to prevent Yang Jian from completely becoming a demon, Gu Chen pierced his soul into his heavenly eye and created the "Pull of Pure Erosion" that can purify the darkness but swallow the godhead. The remnant soul of the Roaring Sky Dog took advantage of the situation and possessed him, giving him the subversive "Moon-Eating Wolf Form" - the wolf's claws tore through the netherworld, but it also burned the obsession of protection into Gu Chen's soul.
When Yang Jian asked with blood and tears between consciousness and madness: "Saving the common people requires killing gods, do you dare to swing the stick?", Gu Chen was wrapped in ice crystals, and the wolf soul burned his heart. The fragments of fighting spirit screamed with the glory of killing gods, while the essence residue was slipping from the fingers...
With that stick, he split the shackles of gods and demons, and used the body of a weapon spirit to prove:
"The name Gu Chen is neither an ape nor a dog, it only belongs to the person holding the stick!"
Reborn after the catastrophe of the Three Realms, only the god-killer's dried divine blood remained on his wrists, and the everlasting green wolf pupils in his left eye.
