I Have a Sword Coming from the Sky

Story background: In the big world of Huanyu, humans, demons, and monsters coexist and conquer each other. There are many sects of human monks, countless countries, and constant disputes. The rise and fall of sects and the change of dynasties occur from time to time. All this was broken one day. In this endless universe, another floating world, the Xuanhuang World, collided with the Huanyu World. On that day, the place where the two worlds came into contact was littered with corpses for thousands of miles, with ruins and no grass growing. The dispute between the two worlds began, fighting for territory and resources. At first it was tentative, but eventually it evolved into a big fight. After the continental plates of the two worlds were stabilized, the Xuanhuang World took the lead in breaking the balance and sent out powerful men who were at the realm of true gods and above. The war between the two worlds was about to begin, but the Great World of Huanyu ended in a disastrous defeat. The two powerful human beings who ascended from the small world in the Great World rose up in adversity, and joined forces to fight against the supreme god of the Xuanhuang Great World. They defeated him, but unfortunately they could not kill him. However, they took back most of the territory of the Great World, and then a city became the boundary, allowing the two great worlds to temporarily live in peace. Twelve thousand years later our protagonist was born in this context.
