I Sold Flowers in Ancient Times to Support My Wife and Daughter

I was hit by an air conditioner unit while walking on the road. I thought I was dead, but I didn't expect to travel back in time to a lame gambler who wanted to sell his daughter in ancient times. Do you want me to sell my daughter? If it doesn't exist, the system will come out! I want to bring Bai De's wife and daughter to live a good life in this world.
