I recommend "After Rebirth, I Spoiled the Villain Northern Garrison King." This is an ancient sweet novel. Back in the past, the protagonist planned to kidnap the Crown Prince and become the Empress Dowager. However, after a few years, the cats and dogs in the palace had a few litters of offspring, but the Emperor did not even have half a son. In one of the scenes, someone told the emperor that the empress had run away from home with her children. The emperor asked if their son was still alive, but in fact, their son was not the emperor's biological son. I hope you like this fairy's recommendation. Muah ~😗
