After becoming a wicked mother-in-law, I won without lifting a finger

My son mooched off me, and my daughter-in-law was bleeding us dry for her own family. All they wanted was for me to die. My husband died in an accident, leaving behind eight million in savings. When I fell ill, they fed me fake medicine and murdered me in cold blood, inheriting everything as if it were their right. When I opened my eyes again, I was back on the day of my husband's accident. He was covered in blood, holding my hand and our son's as he struggled to say his last words: "I have... eight..." My son's eyes lit up instantly. I clamped a hand over my husband's mouth, my eyes welling with tears as I said, "It's eight o'clock, darling. You can rest now. Don't you worry about us!" My husband's eyes flew wide as he took his last breath. My son was stunned. I wiped a tear from the corner of my eye and sneered inwardly. This time around, you won't get a single penny from me.
