On the Day of the Substitute Marriage, I Bought the Xu Family Backhand

The night when Shi Wan married her sister into the Xu family, she handed over a piece of agreement: "For three years, we will not interfere with each other." Xu Han sat in a wheelchair and only replied to her with three words: "Don't be tempted." She thought this was a deal where each got what he wanted. She was acting as his shield in the open, while he was secretly giving her the resources to investigate the cause of her mother's death. Until she got the autopsy report and found that her mother died of poisoning; until she found the man named Chen Li and found out that he was Shi Jianguo's knife; until she rushed into the old house and personally sent Shi Jianguo to the police station—— She thought revenge was over. But the stranger who sent her mother's last words told her that her mother's death was not simple. And the man who said "Don't be tempted" looked at her with complicated eyes: "I was a chess player at first, and then... Became your chess piece." But the chess pieces also want to win the whole game.
