我不蛇蝎怎么毁你所爱
[wŏ bù shé xiē zĕn me huĭ nĭ suŏ ài]
In this context, 'snake scorpion' refers to evil actions. It roughly translates as 'if I'm not ruthless like snakes and scorpions, how can I destroy what you love?', revealing an intent to sabotage or damage something precious to the other party, possibly due to spite or jealousy.
