How Could It Be Me, the World-Destroying Demon?

Five years ago, Xu Haoran traveled to this world, became a child who had just entered the upper class, and awakened the "Super Awesome System" The system told him that this world is very dangerous, but as long as he survives for every day, he can get one level point. Xu Haoran believed it and carefully lived until he was eight years old. Only then did he realize that this world was exactly the same as his previous life. Even the development of history and technology, and even the timeline had not changed, and there was no danger at all. This made Xu Haoran think that this might be a cheating system. However, when he first installed a fork at the age of seven, he discovered that the system was useless! Just when Xu Haoran thought that this life would go on peacefully, a sudden crisis shattered his comfortable life... … "Devil? Agent of gods? Weird? Monster?" "Damn it, you didn't cheat on the dog system?" Xu Haoran was completely stunned.
