Modern forensic doctor Shen Qingge is transformed into a sin slave, with a silver needle in his left hand to save the common people and poison in his right hand to send away evil spirits. In order to find out the truth about the family's destruction, she took the initiative to marry into Prince Zhan's palace and entered into a contract marriage with the cold-faced King of Hell, Xiao Heng——
"My lord, I'll heal your injuries, and you'll help me reverse the case. It's just a deal."
"What if I want to pretend to be real?"
In the royal residence, she poisoned the slaves, and the opening of the medical clinic became famous in the capital; in the court, she performed an autopsy and examined the bones to expose the shady story of the imperial examination, and the noble concubine set up a trap, but she poisoned her to the point of losing her face. The name "Sacred Heart of Poisonous Hands" resounded throughout Dayin, but it attracted the mysterious doctor Yun Zhan to press forward step by step: "Where did you learn your poisonous skills?"
When Xiao Heng bloodbathed the enemy camp for her, and Yun Zhan betrayed the school for her, the two powerful forces finally set off a shocking storm——
The enemy's cavalry is pressing on the border, and the plague is raging in the imperial capital. The couple who were contracted in the past stand on the top of the beacon, holding hands. Shen Qingge's blood-stained white clothes fluttered like a flag, and all the armies were shocked when the silver needle pointed:
"Poison can kill people, but it can also protect the country. In this world, I want its seas and rivers to be clear—and I want you to bow your heads and surrender!"
