At first, Qin Huai didn't quite understand why Luo Jun and Chen Huihong were trying to bolster him up early, hinting that not every spirit can successfully transcend their tribulations, and even if they fail, he shouldn't be burdened with guilt.
After seeing all of Luo Jun's memories, Qin Huai understood a little better.
Often it's not that the spirits can't transcend, it's that they don't want to. Their tribulation was never others, it's their own heart. They can't overcome their own hurdles, can't forgive themselves for various reasons, leading their obsessions to deepen, making it impossible to escape their own distortions.
However, Qin Huai didn't expect that despite what she said, Chen Huihong's actions were quite different. She might have said that Qu Jing's chances of successfully transcending were slim, and even if she failed, Qin Huai shouldn't feel guilty, as these were destinies the spirits had to face, with little others could do.
