After the slave owners went bankrupt, they all wanted to keep me as a mistress.

Mu Qiu transmigrates to a continent called Astram, accompanied by a slave owner system.
As long as you can go bankrupt as a slave owner, you can return to your original world with the magic and knowledge from another world!
In order to spend all the system funds, Mu Qiu spent a lot of money to buy the most expensive slaves from slave traders.
He provided them with the best accommodations, hired top elven mages to teach them magic, took meticulous care of them, and brought them back into contact with the world.
To prevent them from having the idea of ​​staying to make money for him, he mocked and ridiculed these slaves while secretly providing them with opportunities to escape, and continued to help them after they escaped.
When Mu Qiu finally spent all the system funds and was about to go bankrupt as a slave owner, he discovered that the princess of a fallen kingdom, the dragon girl, and the elven princess he had adopted years ago had all returned to the manor, wanting to take care of him when he was on the verge of bankruptcy.
“Master, we’ve finally waited for this day of your downfall. Actually, we knew all along that you deliberately let us go, and we also knew that you had been helping us in secret all along. Now, it’s our turn to help you!”
