In 2147, the "Mirror of Reincarnation" killing cycle in the Yuan Universe started. Shen Hengwu opened his eyes, and saw 99 strange players crowded into a sealed icehouse, with a frozen corpse hanging in the center. The subtitles above her head flashed red: "72 hours countdown to find the murderer and the method, otherwise the consciousness will be trapped forever." What is even more desperate is that she has a "Crime Court" live broadcast chip implanted in her wrist, and her every move is judged by millions of viewers. The barrage flooded the screen: "Are the sacrifices here again?" "Wait to die." But a strange whisper suddenly exploded in her mind: "Daughter, the murder weapon is at your feet." That was Shen Yuan, the dead genius father, whose remnant soul survived through chatting in the background. With his vague words, Shen Hengwu solved three cases in a row, and the live broadcast room changed from ridicule to begging. But the remnant soul becomes weaker every time it is used, and the tracking of the system "Tian Yan" is getting closer and closer. On the forty-seventh day, the secret room was Shen Yuan's old laboratory. The deceased was stabbed thirteen times, and all clues pointed to suicide. Everyone gave up and the barrage said "She's finished." However, Shen Hengwu squatted down and took out a rusty old key from the debris pile - it was her seventh birthday gift, with the word "Hengwu" engraved by her father himself. "Dad, where is the keyhole in the secret room you designed?" The next second, the wall cracked, and the thirty-first corpse appeared. The audience went crazy, the murderer cried, and Tian Yan's red light was already aimed at the back of her neck.
