Tendon-Transmuting Sutra (simplified: 易筋经, traditional: 易筋經, pinyin: Yìjīn Jīng, jyutping: jik6 gan1 ging1) is one of the Shaolin Order’s two supreme internal cultivation texts, alongside the Marrow-Cleansing Sutra. You Tanzhi trained with it and gained immunity to poisons. The sutra transforms the tendons and strengthens the body’s foundation for neili cultivation.
