Ling Huang

Rei Ou was a part of the Seven Fire Dragons of Wei, whose abilities are on par with those of the Zhao Three Great Heavens and the Six Great Generals of Qin.

At some point, Rei Ou along with Gai Mou sided with Earl Shi in his conflict against Tai Ro Ji, Ben Tou and Shou Sen, the other three Fire Dragons, with Tai Ro Ji being personally responsible for the death of Earl Shi's younger sister. This resulted in the deaths of the opposing Fire Dragons.

As a punishment, Rei Ou and the two other generals were incarcerated in an underground prison for 14 years.
