Seal of Love Season 1— Episode 68

Fusheng rescues the demon lord Jing Yuan from peril and takes him as her disciple, stirring unrest among the immortal sects. The celestial lord Qing Chen notices that she bears a striking resemblance to the goddess Xiyun, who sacrificed herself to save the world a thousand years ago, and his heart grows attached. Mu Yao, a goddess who adores Qing Chen, ceaselessly schemes against Fusheng. To protect Fusheng, Qing Chen is forced to marry Mu Yao, yet he cannot ward off her relentless malice. Jing Yuan reveals his true form as a black dragon and withstands the heavenly tribulation for Fusheng; the two plunge together into the Seal of Love and enter the cycle of reincarnation. Years later, Qing Chen finds them, and the three join forces to combat Mu Yao, who has been utterly consumed by her desires and now brings havoc upon the Three Realms.
