In her previous life, she had given everything for him and helped him step by step to become a great minister, but she was not as good as her good sister who slept with him.

When the gentle and loving husband took her life, she realized that the love she thought was as deep as the sea was a joke.

To the end with hatred, Lu Xiang cursed angrily, wanting to let the person who wronged her and harmed her have a terrible death…

Opening her eyes again, she returned to the year she was fourteen years old. She had the same life, but she returned with hatred in her heart.

…

The night was dark and the wind was high, Lu Xiang picked up Chu Jinyan who was hunted down and seriously injured, his eyes sparkled.

“Hey, golden thighs!”

So without further ado, he dragged the person into his room to hide.

“As the saying goes, life-saving grace should be promised with your body… Ah, no, I will repay you with the spring, I saved your life today, and you have to promise me three requests in the future.”

Chu Jinyan: “???”

He doesn’t really want to be rescued…

Later, Chu Jinyan patted his thigh and hooked his fingers: “My concubine, come, I’ll give you my lonely thigh.”
