In the twenty-sixth year of the Republic of China, on the eve of the destruction of Peking City.
Female forensic doctor Gu Qingning received a blood letter: "Professor Fang is at the Shen Mansion."
She pretended to be a poor relative and sneaked into the legendary "traitor's mansion", but in the woodshed in the backyard, she smelled the smell of formalin - the smell of corpses that she was all too familiar with.
Just as she was about to push the door open, a hand covered her mouth.
The dandy young man who only listened to jokes and teased birds during the day was now holding a gun against her waist and whispering: "In some places, the wind is strong and blinding."
That night, a fire broke out in the woodshed and burned completely.
In the firelight, he looked at her and said, "Don't trust anyone."
But she didn't know that this man would block a gun for her later, betray his family for her, and protect her with his life until the end in the fallen city of Beiping.
She also didn't know that when the truth was revealed, she would point the gun at him with her own hands.
——This city, she came to find the truth.
——This city, he was prepared to die.
——But no one thought that they would develop a life-and-death love on these ruins.
