I Entered the Abyss to Raise BOSSes, and the Adventurers Went Crazy

In the battle to destroy the world, the protagonist lands the final blow on the world-ending Boss. The next second, he is reborn ten years in the past alongside that same Boss. A domineering mother, a supremely talented older sister, and a father from a great clan. The opportunities he missed and the family bonds he lost, this time he will hold on to them all. His older sister’s fake-sweet best friend is vicious and deceitful? Kill her. The Zhao family heirs plot against their own clan? Kill them. In this life, there’s no one he can’t kill and no Boss he can’t raise. He’ll claim a place for himself in the human world, and carve out his own territory in the Abyss. In the human world, I’m the savior. In the Abyss, all my underlings have what it takes to end the world. Ever since I gained the ability to enter the Abyss, the Bosses have been begging me to adopt them. Adventurers stare at the Bosses in the dungeons, utterly dumbfounded and losing their minds.
