Mo Yuan | Ye Hua

Mo Yuan

The eldest son of Heavenly Father, and the undefeatable God of War. He is also the Master of Kunlun as well as Bai Qian (Si Yin)'s mentor and Ye Hua's older twin brother. Wise and mature, he is well-respected and revered by all the immortals in the Nine Heavens. Mo Yuan used his soul to seal Qing Cang in the Dong Huang Bell and in doing so, shattered his soul. After he defeated Qing Cang, he spent the next 70,300 years piecing his soul back together.

Ye Hua

A black dragon. Crown Prince of the Nine Heavens. Having borne the responsibility of a future ruler since he was born, Ye Hua has a stoic personality and is more mature than his age. He hides his pain behind his calm exterior, choosing to sacrifice for his loved ones silently. He also prefers to dress himself in all-black clothes because he believes that it hides his bleeding wounds from sight and this has the dual goal of discouraging his enemies as well as causing his loved ones less worry because they are unable to see if his is injured. He meets and falls in love with Bai Qian (Su Su) during a mission in the mortal world to subdue a ferocious demon mount.
