After stepping into the Nascent Soul Realm, he was granted a Dharma Spirit by his sect, the one initially used by Elder Hu, who was one of the Eighteen City Lords of the sect, named "Fire Spirit Venerable".
The Pingdu Sect values hierarchies, and originally, given his novice status in the Nascent Soul Realm, he wouldn't have been appointed to command this Dharma Spirit. However, after Elder Hu was slain with one sword by Zhang Yan, there was no one left to inherit this Dharma Spirit. It so happened that he was chosen to engage in a swordfight, thus benefiting him.
He pinched a spell, chanting an incantation, and suddenly by his side appeared a Golden Armored God, ten feet tall and mighty looking, holding a golden whip in one hand and bearing a Treasure Bead in the other; his whole body was armed to the teeth.
As soon as the Golden Armored God appeared, Wu Han Cheng suddenly leaped up, fusing with it instantly. Then, with a loud shout, he raised the enormous figure.
