My Sister-In-Law Accidentally Dropped Her Children to Death

In my previous life, after my sister-in-law accidentally fell her son and daughter to death, I immediately called for an ambulance to save people, but she insisted that I was the murderer. My parents and husband also helped her identify me. I was hacked to death by an angry elder brother with a kitchen knife. After this rebirth, I decided not to meddle in other people's affairs and find out the truth.
