Transmigrated into a Female-Dominant World, Starting with 3,000 Slaves

I transmigrated into a world where women dominate and men are inferior. Men cannot cultivate, enter the court, or engage in business; they can only stay at home and raise children. I became the most useless young master of the General's Mansion, about to be given to the princess as a male concubine. Then the system arrived: [Ding! Congratulations to the host for activating the 'Slave Owner System'. You have received 3,000 elite slaves. Please check.] Before I could be happy, I saw 3,000 burly, fierce female warriors descending from the sky, kneeling before me: 'Master!' Me: ??? It turns out there is a hidden setting in this world—with the Slave Owner System, men can also cultivate. I smiled. From then on, I trained female warriors, opened spirit stone mines, established the 'Night Prince Manor', and overturned the female-dominated order. When the lofty female emperor wanted to execute my entire family, 100,000 female soldiers arrived at the city gates. I embraced her and whispered hoarsely: 'Your Majesty, how about... I become the emperor?' The female emperor's face flushed red: 'Rebel, how dare you!' I had already carried her onto the dragon throne and silenced her with a kiss.
