I Became Invincible After I Died, So Who Started That Rumor?!

Liu Yu became invincible after death. Once he had dealt with every beast from beyond this world, he looked out over the ravaged world and had his friends and family reborn in the past with their memories intact, so they could kill him just after he awakened. Then his younger sister started following him around all day, always ready to poison him. His older sister founded the largest assassins' guild, with the sole goal of killing Liu Yu! His best friend founded the largest church, preaching that killing Liu Yu would save the world. Liu Yu: “Are you all out of your damn minds? Who started spreading the claim that you become invincible after you die? If someone has to die, let it be you! I sure as hell am not dying!” His younger sister: “What do you do when your own brother is impossible to kill? Asking online, and I need an answer fast!” Future Liu Yu: “Was I really that hard to kill back then? If I don't die soon, I'll become invincible while I'm still alive. Is there any point in dying at all?”
