The Ten Fragrance Soft Tendon Powder was loot Lin Feng obtained when he killed Zhao Min's servant, Ah Er.

This is the strongest poison in the Heavenly Sword world. Anyone who inhales it, regardless of their strength, will temporarily lose all internal strength and become an ordinary person.

In the Heavenly Sword world, countless experts have fallen to this poison. Neither the Six Major Sects nor the Ming Cult could escape its effects.

Unless one is protected by Zhang Wuji's Nine Yang Divine Skill, which renders one immune to all poisons, even the strongest experts must admit defeat before the Ten Fragrance Soft Tendon Powder.
