Fu Yunqi... you really didn't deserve his kind of ending. In his previous life, he was a hero who sacrificed himself for the sake of Linxian city. He survived though but at the cost of being an evil ghost. The evil aura around him slowly corroded his nice personality and he ended being different from how he used to be.

And the most unfortunate thing for him was maybe that he met FL. It could be a beautiful story of a former hero meeting a beauty but what he faced was a cruel unrequited love.

He knew FL loved ML but he still tried his best to protect her by forcefully ripped his soul apart so FL wouldn't being chained by the hell's chain and also giving her his lifespan when she lost her vitality. As a result, he got old faster and his past handsome self was no more.

Until this point, I still hope the author could take a pity of him and let him find his own happiness but no... he's still very much in love with FL until his death. Well, at least FL and ML weren't indifferent to him when they knew his condition. They tried to find a way to cure him but sadly, he's simpy beyond saving.

And Mu An, my good boy. He was FL's first friend and later became her disciple. He also loved FL deeply but chose to hide it and silently protected her as her disciple. Don't worry, his fate was a bit better than Fu Yunqi but he also didn't find his own happiness in the end and even lost the will to cultivate.
