The interstellar pioneer Don Juan activated the "Super Interstellar Empire Development System" in the desperate situation of the alien star sea, and obtained the "tactical humanoid mechanical girl" race full of science fiction, and then embarked on the road of upgrade flow counterattack. In order to repay the huge loan shark left by his father and to regain the earth, his mother planet that has been occupied by aliens for four thousand years, he started from a broken ship and survived in the crisis-ridden ruins of the star field. Through continuous exploration, fighting, and expansion of power, Don Juan established the "Omnic Heaven", fought against the imperial dignitaries with iron-blooded tactics, and completed a passionate counterattack from a debt-ridden "second-class citizen" to the overlord of the stars.
