During the battle with Xiong Wuji, the Taiyi Celestial Capital Thunder Emperor crumbled at the first touch. Almost had no effect. It's just that the power was too small.
But with the nourishment of the Spiritual Qi from the White Bone Mountain Range, the Celestial Dragon Eye also upgraded to an Earth Artifact, and the Taiyi Celestial Capital Thunder Emperor became the central Divine Aspect of the Celestial Dragon Eye.
This was also the third Earth Artifact Gao Xuan had refined. From Gao Xuan's perspective, its power was decent. It should be no problem to use it to kill the likes of the Heaven-Confusing Demon Emperor.
If he were to encounter the Five Elements Ancestor, well, the Taiyi Celestial Capital Thunder Emperor would struggle. The protection of the Five Elements Earth Evil Divine Light is meticulous, when they turtle up, it's really hard to break.
The next step, Gao Xuan went to Mengze Lake.
