Ye Xuan transmigrated back to when he was an infant cuddling in the embraces of his nine older sisters. He activated the God-tier Sign-in System.

[You are hugged by your eldest sister, who is the COO of a financial conglomerate. You signed in and obtained RMB100000000.]

[You are fed medicine by your second sister, who is crowned the God Hand. You signed in and acquired god-tier acupuncture skills.]

[You trained along with your third sister, who is a Martial Arts Grandmaster. You signed in and your overall physique improved.]

[You live-streamed with your fourth sister, who is the top news anchor in the country. You signed in and acquired extraordinary good looks.]

……

Ye Xuan could sign in daily!

After staying in the city and signing in for eight years, Ye Xuan had accumulated an astronomical amount of wealth and become a billionaire.

On his eighth birthday, his nine sisters were forced by the grand elder of their clan to get married. Just when everyone had lost hope of turning things around, Ye Xuan hopped down from his eldest sister’s embrace and said, “You’re marrying my sisters off against their wills. Have you consulted me about this?”

The young man living in a frontier mining village, Elliott, lived in estrangement there.

The reason was because he carried the blood of the Demon Race, and had an unusual face, with two small horns growing from it.

Several years after his mother – his only family – died, a young woman who called herself an acquaintance of her mother’s came to visit, and once she knew of Elliott’s existence, displayed the traits of a succubus, and whispered thus:

“From now on you will ravish many women, steal many lives, and trample over the world, you shall dominate. But to start … you will dominate me, violate me, please”.

Unable to wield a sword, nor kill his opponents with magic, the mixed-blood young man who could only grant a slight bit of magic into matter, used information, tools, and traps, repelling enemies, ravishing women, making them submit and fall into demonhood, and dominated them, surviving in a ruined world.

This is the story of the young man who was the Lord of the perilous place of fear, one that never allows a guest to leave, the “Man-Eating Dungeon”, and the women whose lives had been derailed by him.

Ling Jing Shu lived with humiliation and heavy burdens all her life, and only at the moment before death, she suddenly woke up and repented. If god gives her a chance to live for a second time, she will say three words to the man who let her down: You Get Lost!!
