蛇蝎心肠的我百毒不侵
[shé xiē xīn cháng de wŏ băi dú bù qīn]
Translating as 'I, with a heart as venomous as snakes and scorpions, am immune to all poisons'. This suggests a strong, fearless character that is indifferent to hurtful emotions, almost saying that being hardened prevents being emotionally harmed.
