She became Qianqiuling, the greatest assassin in the world, then turned into the divine physician Ning Qianqiu to escape the life of an assassin, and later became Mo Mo again to seek revenge. The thorns and muddy roads along the way never turned Mo Mo into a cold-blooded, heartless person. She keeps moving forward, both saving others and being saved herself. Having experienced the lives of assassins in both ancient and modern times, she never let the disappointments of the past shake her faith in modern life. Instead, she thrives.
The leads save and heal each other, bringing warmth into one another's lives and helping each other become who they are.
