My System Woke Up: God-Slaying and Going Home

Trapped in a world teeming with ancient gods and hidden monsters, Lin En finds himself reborn not as a hero, but a five-year-old orphan. Bullied by kids, subjected to a corrupt welfare home, his powerful past-life knowledge is useless without the dormant \"Supreme Sweet Potato System\" that was supposed to guide him home. His only wish is to return to his original world, but how can a child possibly challenge a reality ruled by deities? Just as despair sets in, a chance encounter with a lonely, innocent boy, destined for a legendary future, triggers a powerful, resonant heartbeat. Lin En's long-crashed system roars back to life, revealing its true purpose: to help him \"make up for regrets\" in this \"God-Slaying World.\" Every regret undone, every past mistake mended, pulls him closer to his ultimate escape. But what if the deepest regrets belong to the gods themselves, and fixing them means an all-out war?
