Auction Rebates Billions of Times, I Became the Ancestor of the Human Race

【10,000x Return + System + Force Development + Easy and Fun】

Su Hao traveled through another world and inherited the Xia clan's Qincheng Haoran Auction House.

The game starts with binding to the god-level auction system. As long as the items are auctioned off, a reward of up to a billion times the critical hit value will be returned!

"Ding! Congratulations on successfully auctioning the first-grade, top-grade technique "Eight Extremes Collapse," triggering a billion-fold critical strike and receiving a rebate reward of the supreme-grade technique "Huangting Daojing"!"

"Ding! Congratulations on successfully auctioning the sixth-grade, low-grade headdress [Nine-Colored Phoenix Crown], triggering a billion-fold critical hit and receiving a rebate reward of the supreme-grade treasure [Character Marriage Card 'Empress']!"

A few years later, the alien race invaded the human race on a large scale. They thought they had a sure victory, but were killed by Su Hao.

The alien gods were extremely panicked: "How could the human race still have such a terrifying hidden ancestor in the world?!"

Su Hao: "Huh? How come I'm the only one who doesn't know that I'm the hidden ancestor of the human race?"
