Stellaris: Starting from Fortress of the Solar System

After Kyushu completed its first super-light test, a civilization deduction disk appeared in front of Gu Huai. The first line is: [Countdown to the demise of Kyushu civilization: 179 days. Superluminal fluctuations expose the coordinates of the solar system, and the Balka Purifier fleet from the depths of the galaxy is approaching. They don't negotiate, they don't trade, they don't accept surrender. They only remove all "unauthorized civilization". In order to defend their home planet, Kyushu was forced to transform the entire solar system into a war fortress. The moon builds ships, Mars lures enemies, asteroids lay mines, Jupiter sets ambushes, and blue stars defend. Gu Huai can deduce the future of civilization, but he cannot win the war out of thin air.

When the countdown to planetary purification came over the Blue Star, Gu Huai looked at the devastated solar system and said only one sentence: "Kyushu civilization can fight to the death." "But never accept purification."
