My Vegetative Wife Is the Female Emperor

My name is Feng Qi, a penniless transmigrator. As luck would have it, the eldest young lady of the Ji family fell into a coma, and I was chosen. Fortunately, I bound myself to a System. As long as I interact with people of noble status, I can earn points and exchange them for all kinds of wonderful things. But one day, after my wife woke up, I discovered another soul hidden inside her. She claimed to be the reincarnation of Empress Fuyao! Well, this is... twice the fun!
