百毒不侵其实是麻木至极孤独成性不过是厌恶人心
[băi dú bù qīn qí shí shì má mù zhì jí gū dú chéng xìng bù guò shì yàn è rén xīn]
The name suggests that being indifferent to various influences or troubles ('immune to all poisons') actually results from extreme numbness, and the habit of feeling lonely simply because one is disillusioned with human nature. It reveals a jaded, detached state caused by disappointment.
