In a bustling capital, there are people who wear masks. They cannot be seen or touched, and are everywhere, like the air. They usually appear only when evil arises, to destroy it. People call them the Evil-Slaying Envoys. Whenever the Evil-Slaying Envoys appear, people say the June snow can finally stop falling. But their defiance of the authorities deeply angers the court, so it establishes the Extermination Office, charged with capturing the Evil-Slaying Envoys and portraying them as the most wicked of criminals. After an unexpected encounter, Yan Rugui saves Zhang Jing. They dislike each other at first, but gradually fall in love. Yet for certain reasons, they become enemies, unaware that much more awaits them, including an even greater conspiracy. Watch as they expose the plot and join forces to solve the case. At their first meeting, Zhang Jing thinks Yan Rugui is a weak scholar and despises him. Yan Rugui thinks Zhang Jing is a shrew: stunningly beautiful, but with a terrible temper. From fighting and loving each other to falling deeply in love, it is all a matter of fate. (Zhang Jing, a seemingly fierce merchant’s daughter who is actually the cold and ruthless leader of the Evil-Slaying Envoys, VS Yan Rugui, a seemingly frail scholar who is actually the ruthless and merciless commander of the Extermination Office)
