My Useless Little Brother Alphas

Everyone in the Third Galaxy knows that the royal family there carries a hereditary case of chronic laziness. To stop these people from exploiting loopholes, refusing to have heirs just to escape their royal status, the council even changed the line of succession. Now, only royal children who fulfill their duty to have children can renounce their status and become free citizens. So the crown prince, who married an Alpha, got the short end of the stick. He jumped three ranks in one leap and went straight to becoming His Majesty the Emperor, after his father, whose laziness was at its terminal stage, dumped the throne on him. But the new Emperor hasn't given up on his dream of becoming a free citizen. So he waits, hoping to catch his younger brothers in a compromising position, plotting to label the lot of them incapable of having children, then drag them back to the palace to be worked like slaves by him and his dear wife! But can he really pull it off?
