It was a cross-world novel. The protagonist lived a wealthy life after crossing over and learned martial arts. Later, he bought a girl who sold herself to bury her father. The protagonist was four years younger than the girl. At that time, the main character even taught a cannon fodder man a lesson for the girl. After returning home, the protagonist lived and slept with the girl. However, the protagonist was tied up with a rope when he slept. Later, the protagonist's family was destroyed. When the protagonist's mother died, she found out that the girl was the murderer's mole. Although the main character managed to escape, his legs were crippled and he was found by the girl. The girl felt very guilty towards the protagonist and liked him very much. She had been taking care of the protagonist and even helped him make a wheelchair. However, the girl still did not realize that the protagonist was a woman. The protagonist was unmoved by the girl's care and affection and escaped from the trapped valley. However, he was still found by the girl and the murderer's son, and he was once again imprisoned. However, the protagonist began to practice martial arts diligently and still ignored the girl. The girl also felt it in her heart. She listened to her subordinate's suggestion and planned to seduce the main character. The protagonist was indeed tempted, but the murderer's son appeared in time. The girl's seduction failed, and the protagonist's identity was not exposed. Later, the protagonist finally mastered martial arts, defeated the murderer's son, and left the valley. The girl followed the protagonist out of the valley. Finally, the protagonist was moved by the girl's affection and accepted the girl again. However, there was a new problem-the girl did not know the identity of the protagonist. However, the inn only had one room for them to stay in. Just as the protagonist was thinking about how to respond, the girl had already carried the protagonist upstairs.
