Shen Heng, an ugly girl who was killed by her legitimate sister and a scumbag in her previous life, was reborn as a surrogate sister on the day of the palace draft. She wanted to pretend to be crazy and act stupid and was eliminated and went home to farm, but she was unexpectedly turned over by the tyrant every night. She worked step by step to tear up her legitimate sister's conspiracy, but she didn't know that this cold-faced emperor had already seen through everything and was waiting for her to reveal the shocking secret of the murder case in her previous life.
