In the previous life, we were used as a stepping stone by the "Destined Protagonist" and our whole family was wiped out. After my rebirth, I discovered that my father is the hidden king of killers, my mother is the poisonous queen who faked her death, my sister is the scheduled villain witch, and I am bound to the system of "harvesting the protagonist's luck". Okay, then in this life, our whole family will act together and play the leading role to death.
