以我粉身碎骨佑你一世无伤
[yĭ wŏ fĕn shēn suì gú yòu nĭ yī shì wú shāng]
A poetic way to express unwavering commitment to protect another, meaning 'I would sacrifice my very existence to keep you safe throughout your life.' It illustrates extreme devotion, putting one's well-being entirely second to that of the loved one.
