It Makes Sense for My First-Level Civilization to Have a Star Destroyer.

Xia Hua traveled to a parallel world and awakened the black technology weapon system. By completing the tasks issued by the system, you can create weather weapons, genetic weapons, and even Star Destroyer Motherships! When Xia Hua was building technology, alien civilization discovered the solar system through interstellar travel, found a viable blue star, and launched an interstellar war. When the whole world felt that it was about to perish, Xia State stood up. "What is that, a flying aircraft carrier? Can it destroy an alien spacecraft with one shot?" "Xia people actually appear in outer space without wearing spacesuits? Can they still fly?" "Is this a quantum laser cannon? This thing can also be built!" When seeing weapons that far surpassed the first-level civilization, the alien civilization was frightened and wanted to escape from the solar system. But a figure instantly blocked the black hole and blew up the starship with a slap.
