The Hidden Fang

Zoe Soot, a skilled doctor with a distinguished medical background, earns the emperor's praise as the top physician in the palace. However, consumed by jealousy, a vengeful consort orchestrates Zoe's brutal execution and orders the annihilation of the entire Soot family. As the sole survivor, Zoe’s sister, Yael Soot, refuses to flee. Instead, she adopts the identity of "Luna Yale" and enters the palace as the consort’s servant.
