Ling Yue is the top female agent in the 21st century who is both a doctor and a poisoner. She belongs to a mysterious special organization. She can revive the dead with silver needles and make them invisible with poison powder. She is meticulous and decisive in killing. However, due to betrayal within the organization, she was blown through time and space by a bomb during a mission. After traveling through time, she became the legitimate daughter of the good-for-nothing Marquis of Zhenbei who was falsely accused of collaborating with the enemy and treason of the Dayin Dynasty. The original owner was pushed into the lotus pond and drowned by her concubine and her fiancé, and Ling Yue resurrected her body.
Xiao Jue: The commander of the secret guard battalion of the Dayin Dynasty. On the surface, he is an idle prince and the "Night King", but in fact he has a large number of soldiers and secret plans. He needs to rely on special medicinal materials to survive due to a strange poison in his body, which intersects with Ling Yue's poison-curing skills. He has a cold personality, a deep castle, and is always on guard against others, but he is attracted by Ling Yue's uniqueness and power.
