It's Only Natural for My Level One Civilization to Have a Star-Destroyer

Xia Hua transmigrates to a parallel world and awakens the Black Technology Weapons System. By completing the missions issued by the System, he can build weather weapons, genetic weapons, and even planet-destroying motherships! As Xia Hua develops technology to make Xia grow stronger, an alien civilization discovers the solar system through interstellar travel, finds Blue Star, a world where it can survive, and launches an interstellar war. Just as the whole world believes it is doomed, Xia steps forward. “What is that thing? An aircraft carrier that can fly? It took out an alien spacecraft with one shot?” “Xia’s people can go into space without wearing spacesuits? And they can fly?” “Is that a quantum laser cannon? They can build one of those too?” When the alien civilization sees weapons far beyond the level of a Type I civilization, it is terrified and tries to flee the solar system. But a figure instantly blocks its passage through the black hole and blows up the interstellar spacecraft with a single slap.
