After Being Made into a Ruthless Puppet by the Princess

The princess wants to get married and asks me to help her. After the incident was completed, she only got the position of concubine. In order to become the main wife, she forced me to take the soul-destroying grass. "Shi Feng, you are very skilled in martial arts, and my husband just wants you to be loyal to him." She said decisively, completely forgetting that she had said she wanted to marry me. As she wished, I became a ruthless puppet who was only loyal to her husband and had no love or hatred for her. But she cried and begged me to look at her.
