On their wedding night, she didn't wait for the groom, but she waited for jail time, just because the deceased was the savior he was prepared to commit himself to. She ignored him, stayed away from him, and vowed to solve the mystery and prove her innocence. He humiliated her and ignored her, but he was fascinated by her unique talent in solving crimes. Mandarin ducks weeping blood, strange red lanterns, gold guillotine cases, bizarre life experiences... Are these carefully planned murders completely unrelated? Or inseparable? The clues are intertwined and reveal the rise and fall of the two dynasties. The more she investigates, the deeper she gets trapped, trapped physically, emotionally, and mentally, until she steps into an abyss of eternal destruction. Walking on thin ice, every step you take will bring you closer or further away from the truth... Opportunities are reserved for those who know how to be patient. They will work step by step, stay in tune with each other, and eventually see the truth to the light of day. Fortunately, in this life, I never forget my first love and live up to the years.
