How Deep Is Yueyuan's Love?

Long Zaiyuan was originally the crown prince of the Dragon Clan, and Xue Lian was just a little fairy who guarded the Three Realms River. The two people, who had no connection with each other, fell in love by chance, but were beaten by the Dragon Lord and sent to the lower world to endure the pain of seven reincarnations. While Long Jun was saddened that his beloved son was not doing his job properly, he also made a vow: Let the two of them meet but not know each other, know each other but not fall in love, and fall in love but not stay together in these seven reincarnations... But things are unpredictable. After six reincarnations, the two finally met again in the seventh life... It's just that this encounter was so short and they finally parted...
