In the previous life, Shen Jingchun was the delicate bird kept in the palm of Jingyuan Hou Xiao Beichen's hand, and the perfect substitute for Bai Yueguang in his heart. She washed her hands and made soup for him, and dissipated all her wealth for him, but in the end, he and his Bai Yueguang, her good sister, jointly poured a bowl of poison into her mouth, leaving no trace of her body. Once reborn, he returned to the night when he was sent to his bed. This time, she was no longer a pawn at the mercy of others. She would put on the most innocent and harmless mask, lie in his ear, and spit out the most poisonous snake message. She wanted to become his only addiction, the sharpest blade, and personally drag those who betrayed her into an endless hell one by one. Lord Marquis, your Bai Yueguang is back, but this time, she has tempered the poison and is here to claim her life.
