Parents and Adopted Daughter Panic After Using Sulfuric Acid to Destroy Fingerprints

The first thing I did after my rebirth was to immerse my hands in sulfuric acid to destroy my fingerprints. In my previous life, my adopted sister killed someone, but she took out my fingerprints and left them at the scene, making me the scapegoat. Not only did my parents not seek justice for me, they also gave perjury to my adopted sister and took the lead in exposing me as a "murderer" online. On the day I was executed, they took their adopted sister to the island to celebrate the aftermath. When I opened my eyes again, I was reborn and returned to the hour before my adopted sister committed suicide. This time, I will make it impossible for them to commit perjury.
