"Not bad." Yang Zhengshan flicked out a spear flourish and nodded in satisfaction.
This Thunder Fire Spear had been custom-made for him. Not only could it let him better control Yi Wood Divine Thunder and Solar True Fire, it could also strengthen the combat power of his Spirit-Swallowing Dharma Body.
The reason why Yang Jizhen had designed the Thunder Fire Spear's maximum length to be twelve zhang was that when Yang Zhengshan used the Spirit-Swallowing Dharma Body, his physique would grow dozens of times larger.
Before, the Spirit-Swallowing Dharma Body had not been of much use to Yang Zhengshan, because in battle, size did not increase combat power. On the contrary, if his body was too large, it would affect his agility instead.
Previously, the Spirit-Swallowing Dharma Body's greatest use had been to replenish Yang Zhengshan's magic power. When his magic power consumption was too great, Yang Zhengshan could use the Spirit-Swallowing Dharma Body to forcibly devour the spiritual energy of the Spirit Source Land and replenish his own magic power.
Now that Yang Zhengshan had this Thunder Fire Spear, however, he could use it in concert with the Spirit-Swallowing Dharma Body for close-combat suppression.
"You worked hard!" Yang Zhengshan put away the Thunder Fire Spear in satisfaction and patted Yang Jizhen on the shoulder.
"It wasn't hard, haha. With this experience, next I can try refining a Spirit Artifact on my own!" Yang Jizhen said, his face full of excitement.

With the experience of modifying the Thunder Fire
