How did empire of the sun's original sin rebellion develop its economy quickly and stay rich?

First, we must occupy many planets. In order to occupy the planet, we must develop the army. For troops without a main planet, free capital ships and 10 light frigates should be used. There should be about four colonial ships, two asteroids (the dead should be in the front, not in the back, otherwise it will be heavy), and two planets should be colonized first (about five territories, different maps are different, and it is best to have twice as many computers). If the Star Fortress can upgrade its trade, build more, usually in the center of the galaxy or in the companion field. Anyway, the farther the distance, the higher the income. Of course, safety comes first. If you have more money, you can immediately buy minerals and crystals to upgrade your fleet. Don't save money, build it if you have it, and slowly the strongest fleet in the galaxy will come out. Of course, it will be harassed by the enemy, and it is impossible to save money and expand the development fleet at the same time.
