On a thunderous night, Shen Ge, the commander of the Ming Dynasty's Jinyi Guards, woke up from the mountain of corpses and sea of blood six hundred years ago and became the personal bodyguard of the wealthy daughter Lin Xingqian.
In this modern world where the rules are overturned, his murderous intention is the biggest "trouble". She was racing, and he was chasing the car with ease; when she was attacked, he instinctively wanted to draw a knife to "clear her out" - until she held his hand and told him firmly: "Shen Ge, the police are here."
From then on, the most dangerous bodyguard in history began to learn to become a "modern person". He used Jin Yiwei's investigative skills to counteract tracking, used interrogation methods to disrupt business conspiracies, and stifled all crises invisible. He went from an out-of-place "antique" to the most reassuring shadow around her.
In their company day and night, the rebellious and indulgent eldest lady gradually saw through his pure loyalty under his cold and hard shell; the killing weapon from ancient times also tasted the warmth of being cared for and protected for the first time.
When the truth about time travel is revealed and the passage connecting the two eras is opened again, Shen Ge faces the ultimate choice: return to his hometown where his mission is, or stay in this world with her?
He put away the embroidered spring knife that once represented identity and strength, and his eyes were as firm as before.
"My country collapsed six hundred years ago. And my bright moon is right in front of me right now."
