The martial world is divided between the Six Righteous Sects and the Demonic Cult's Netherworld Palace. Ten years ago, the righteous sects joined forces to besiege the Netherworld Palace, causing the Demonic Cult's leader to fall and its Saintess to disappear.
● Heroine: Jiang Li, a mute physician from Medicine King Valley on the surface, but in truth the sole surviving heir of the Netherworld Palace. She bears a deep-seated vendetta, but after being gravely wounded and losing her memory, she is saved by the son of her enemy.
● Hero: Gu Changyuan, the only son of the righteous alliance's leader, hailed as the Jade-Faced Sword God. Gentle as jade, he has no idea that the woman he saved is the very Demonic Cult remnant his father personally struck down years ago.
He teaches her swordsmanship and righteousness, while she exploits his trust to hunt down her enemies. When the truth comes to light, will he sever his feelings with his sword, or defy the world to protect her?
