Shen Qing is a veteran of the northern frontier army. All he wants in this life is to save enough 400 taels of silver to go back to the countryside and buy ten acres of land, build three tile-roofed houses, and buy an ox. Until Su Nianwan, a medical girl with worn-out feet, handed over the jade pendant and said, "Send me to the capital."
Shen Qing answered. She didn't know that Su Nianwan was responsible for the annihilation of her family, she didn't know that there was a knife hidden in her medicine box, and she didn't know that the pursuers knew where they were every step they took.
Shen Qing originally thought it was an ordinary escort business from Qingshui Town to the capital, which was 1,200 miles away. However, night attacks on inns, poisoned tea, and ambush in the wilderness followed one after another. The pursuers came from an organization called "Underwater". Su Nianwan's father was once murdered for recording the prescription for "Wangyou Powder". This drug, which can suppress people's emotions and turn living people into walking corpses, is being used on a large scale by soldiers in military camps in northern Xinjiang.
Shen Qing was forced to go from being a bodyguard who "worked his life for money" to being involved step by step in this military conspiracy that spanned the border, Dali Temple and the capital. She formed a three-person investigation team with Su Nianwan and Dali Temple female official Helan. They changed from being hunted prey to hunters who actively pursue the truth. Going north, they uncovered the cruel truth about the "Medicine Slave Soldiers" and discovered that the mastermind behind the scenes was far away in the capital, and all the clues pointed to a name that had disappeared for three years - Shen Hechuan.
This is from a transaction of four hundred taels of silver to a pursuit leading to death. Shen Qing finally understood that some sword flashes were not for money, but for those who could not be erased.
Purpose: Those whose names have been erased by medicine must be remembered by those who refuse to forget.
