+![thuai7](resource/THUAI7.png)
+
+在不久的未来，随着 AI 技术的飞速发展，人类探索太空的步伐也大大加快。太空安全对于国家安全的重要性与日俱增，因此，太空建设也成为了各国的重要任务。在这个全新的赛场上，由 AI 控制的高度自动化的太空舰船成为了竞技的主力。它们可以在太空中自由穿梭，执行各种任务，如资源采集、建筑建造、太空战斗等。 新领域的探索总是伴随着风险，太空中的舰船也不例外。在太空中，舰船之间的距离遥远，通讯延迟巨大，因此，舰船之间的冲突往往是在瞬息之间决定胜负。在这个竞技场上，AI 的控制能力、决策速度、战术策略等都将成为决定胜负的关键。
+
+在远离地球的太空中，为了建立起牢固的防线，保卫美好的家园，一场激烈的战斗即将打响。你将扮演舰队指挥官，带领你的舰队在太空中展开一场激烈的战斗，为了最终的胜利，你需要制定合理的战术策略，部署舰船，利用资源，应对敌人的进攻，最终摧毁敌人的基地，夺取最终的胜利。
