Life Simulator: Start by Rescuing a Little Girl

For my first simulation, I traveled to the world of immortality, became a refugee fleeing from famine, rescued an abandoned baby girl, and became her brother. We depend on each other. At the end of the simulation, I sacrificed my life to protect the grown-up girl and died blocking the demon cultivator. The light disappeared from the girl's eyes. In the second simulation, I went to a world where steam and magic coexisted. I studied magic and took a demon girl with impure blood living on the streets as a student. I taught her humanity, brought her to experience the beauty of the world, and trained her to be a miracle beyond the gods. The simulation ended, and I died in front of the witch due to my mortal lifespan. Simulation after simulation, encounter again and again. I suddenly felt something was wrong: "Wait a minute, why did you come to see me in reality?" This novel and its characters are purely fictitious.
