Let's Go Down the Mountain! Ancestor

Immortal Lord Mo Yan descends from the heavens with a marriage contract from his past life, seeking to reunite with his reincarnated lover, Yun Wuxin. However, Yun Wuxin refuses to recognize him due to her grandmother's critical illness, Zhou family's forced marriage, and her trauma from the 'substitute' incident. Behind the scenes, Zhou Chang'an and his master covet Yun family's half-demon bloodline and plot to brew talismans. As Mo Yan heals his grandmother, dismantles the conspiracy, and battles the heavenly tribulation, he strives to prove to Yun Wuxin that his love is not a phantom from a past life, but the woman of this one.
