百毒不侵的我也曾遍体鳞伤
[băi dú bù qīn de wŏ yĕ céng biàn tĭ lín shāng]
"Invincible me has also been bruised all over" reflects an attitude of resilience despite having experienced many hardships. Despite the claim of being impervious to various poisons symbolically (harmless against negative influences), they have still endured a lot of injuries from these past challenges.
