To Yun Lintian's knowledge, red lightning was considered the medium-level among the lightning elements. However, its destructive power was high enough to kill the Essence Profound practitioner, like Yun Lintian. If it wasn't because he was the Beyond Heaven King's Crown and Beyond Heaven Profound Vein owner, Yun Lintian wouldn't dare to go there.
When Yun Lintian was about to move forward, another lightning bolt was descended again. This time it was a white color, the weakest one.
Yun Lintian was puzzled. Could it be there was every color here? While he was thinking, a golden lightning bolt struck down in the distance, and this had confirmed his guess. This place should have every kind of lightning.
Discovering this, Yun Lintian immediately became excited. Perhaps this place really had the lightning element source. Without further ado, Yun Lintian hastened his steps toward the Thunder City.
