The End of the World

In the vast universe, human beings are just a speck of dust. One day, a substance called "black hole" was quietly sweeping across the entire universe. The planet described in the story, Halpe, had long been slowly eaten away by "it". Humanity had to start paying attention to this serious problem, and one of people's responses attracted the attention of an alien god. He sent down a piece of power, and the future of the story changed.
