After Rebirth I Refuse Favoritism; Three Ungrateful Sons Regret It

In the countryside they say an unlucky old woman gets three sons at her deathbed: the pill son, the rope son, the water son. I thought I had millions in demolition money, and three sons I'd spoiled rotten their whole lives, so I was sure I'd live out my old age in peace. But when I had a stroke and ended up paralyzed, my three sons decided I was a burden, and tied me up with rope and dragged me into the abandoned pigsty. They split up everything I owned, and watched me drink down that bottle of filthy water laced with rat poison.
