You Were Supposed to Build Weapons, So Why Did You Start an Interstellar War?

【Satisfying Read + Cutting-Edge Tech + Mechs + Promoting Huaxia Civilization + Building a Technological Superpower】 Military engineer Xu Tian is reborn one year before Earth is invaded. He also acquires the Interstellar System. Yet Earth is still at a primitive stage of civilization. No stargates, no starships, no mechs! Xu Tian: “If we don’t have starships, we’ll build them! If we don’t have mechs, we’ll build them! If we’re missing something, we’ll build it ourselves!” Before long, the Dragon Kingdom has built a whole lot of starships! When the Titan race arrives, they’re stunned. “Weren’t they supposed to be a low-level civilization? How do they have interstellar fighters? And, most importantly, why is this planet’s military so strong?” “How can a low-level species keep beating our advanced civilization into the ground? Is there no justice, no law?” Titan commander: “I just wanted a planet to use as a dump. I didn’t know I’d mess with the wrong people! If I can’t beat them, I can at least run away, right?” Apocalypse Empire: “Why is this yellow-skinned kid so damn good?” Yinchuan Federation: “You’re using the Tyranids to make skewers?” Force-wielding warriors: “How can a low-level species like you have a lightsaber?” Years later, Huaxia-made goods are all the rage across the universe. Xu Tian’s fleet has become the most powerful in the universe. The races of the universe say, “If you haven’t heard of Xu Tian or Huaxia civilization, you’re out of touch.”
