Lei Ming, who died suddenly while doing the Saint Thunder Ray mission, transmigrated to the Douluo Continent and was taken in by the Dean of Tianshui Academy. He grew up and matured together with Shui Bing'er.
He awakened his martial spirit at the age of six, possessing innate full soul power.
However, he was unable to absorb a spirit ring, which prevented Lei Ming from becoming a spirit master.
After eight years of cultivating his soul power, the unknown martial soul flashed with golden light, as if something had broken out of it.
Years later, Lei Ming grew wings on his back, wielded a golden sword of lightning, and pointed straight at the realm of gods.
"When thunder rolls across the clouds, when lightning illuminates the earth, I come with the storm, bringing the wrath of the gods!"
