Landlady who likes to hoard land

Reborn after her divorce, Wang Chengyu's biggest dream is to become a landlady with her son. She'll build a huge farm, growing flowers, vegetables, fruits, rice, wheat, and soybeans, raising chickens, ducks, and cattle—basically, everything! She'll hire a few hardworking laborers, and then she can live a carefree, leisurely life for the rest of her days. But the learning system won't allow it! She can buy learning hours with merit points? Fantastic! No more worrying about her child's studies! Study papers, the child is tired, what if he's naturally slow-witted? Everyone has their own talents, no problem if he doesn't get into high school, vocational colleges welcome you! Don't look down on me, or I'll pinch you...
