He is the chief assassin of the most mysterious assassin organization "Shadow Pavilion" in the world - Mo Ying. He is ruthless and never survives under the sword. She is Shen Qinglan, the youngest female censor in the imperial court. She is upright and vows to rid the world of evil. The two were supposed to have nothing in common, but they were tied together by fate because of a shocking conspiracy.
Shen Qinglan was ordered to investigate a major corruption case, but the clues pointed directly to the "Shadow Pavilion". Mo Ying received the mission to assassinate a "court eagle dog", and the target was Shen Qinglan. The two faced each other many times during the pursuit and counter-pursuit, but they were never able to determine the winner. Mo Ying's sword never failed, but he hesitated many times when facing Shen Qinglan; Shen Qinglan's resourcefulness was invincible, but he was repeatedly frustrated when facing Mo Ying.
As the investigation deepened, the two discovered that the conspiracy actually involved a long-standing royal secret. They have to temporarily join forces to uncover the truth. However, during the cooperation, Mo Ying's cold-bloodedness and Shen Qinglan's justice constantly collided, and the two became both partners and rivals.
In the end, the truth was revealed and the conspiracy was shattered. Mo Ying put away her long sword and said calmly: "Between you and me, it has nothing to do with romance, only victory or defeat." Shen Qinglan nodded: "Next time, I will definitely win against you."
A duel between wits and bravery that has nothing to do with love. See how the killer and the censor work together to break the situation, but they are enemies of each other!
