The Longest Promise (Season 1)

The Longest Promise (2023) is a Chinese fantasy drama you can watch online on iFILM. It stars Xiao Zhan, one of mainland China's most in-demand actors, opposite Ren Min in a sweeping tale of duty, magic and a love that breaks the rules.

The story unfolds on the Kong Sang Continent, where rival clans hold a fragile peace and sorcery is tangled up with court politics. Prince Shi Ying, banished to Jiu Yi Mountain on a false charge, devotes himself to cultivation — until he crosses paths with Zhu Yan, a princess of the Chi Yi Tribe fleeing an arranged marriage. Chance makes her his disciple, and a fated jade bone binds the two to an old prophecy. Feelings grow despite the line between master and student, and a clan war eventually drives them to opposite sides.

Directed by Jiang Jiajun and adapted from Cang Yue's novel, the series delivers what xianxia fans come for: elaborate costumes, airborne qi duels and a years-long doomed romance. It lands best with Xiao Zhan's followers and anyone who enjoys slow-burning fantasy melodrama steeped in Eastern myth. Stream every episode of The Longest Promise (2023) online on iFILM.
