Compared to the first time he upgraded the puppet, Chu Yi was much faster this time.
After all, he had the experience from last time, and many procedures were already familiar to him. About an hour later, the Earth Level puppet, Zi Xuan, was fully upgraded.
Looking at Zi Xuan, whose appearance hadn't changed much but whose insides were completely transformed, Yang Fan nodded silently.
Next, it was time to wrap Zi Xuan entirely with his Immortal Fire.
Halfway through the refinement, Chu Yi suddenly remembered the purple crystal stone he had obtained earlier.
Pang Dachuan had once told him that this type of crystal stone was very hard, but extremely flexible.
If he placed this piece of crystal stone inside Zi Xuan's body, it could increase the puppet's sturdiness and flexibility. At that time, Zi Xuan's attack power would be greatly enhanced.
