In the original plot given to Qing Xi, Yue Ran was almost drained of all her spiritual power by the Sword of the Demon and nearly died in the process of breaking the seal in the demonic sword. Jiang Wen Xiu was soft-hearted when he saw such a scene and thus "kindly" rescued the life of Yue Ran from the other sect members' pursuit by shoving her off the cliff, which would save her from a more gruesome end--meaning dying by her former comrade's hands.
Hai Bing Tu: ???
Long Yuan: ???
Yue Ran: ???
Ruan Ruan: Is that not the same thing? It is worse to die at a crush's hands than a former comrade's hands.
Lan Jin: Rawr, rawr! (So full of nonsense!)
Owing to the fact that Long Yuan had gotten out of the seal, he was able to protect Yue Ran in time, and that was why Yue Ran could land safely and soundly in the end, and her life was no longer in peril.
