Lagrange: Rebuilding the Empire of the Sacred Stars

[Big ship and huge cannon + racial mysophobia + human supremacy + burning glass] Live a new life. Born into a regular old-fashioned family in the Third Federation of Humanity's Interstellar Republic. After being forced to sign the "Pioneer Exploration Plan". I thought I could just die on a pioneering ship. But he didn't expect to get the Lagrange game he played in his previous life and inherit all the blueprints from his previous life. Then, Federation, foreign race! My fleet covers the sky, are you ready to be baptized! (In the early stage, companies or federal scientists or researchers will be captured and robbed. Modify the ships in Lagrange to change the current situation where the tonnage does not match the weapons. It's not a complete Lagrangian Galaxy, the background is for reference. )
