The Demon Empire in the universe was reborn and came back! Enemies should kneel down in front of him! Beauties should lie down in front of him!

“I am a demon. I enslave gods and immortals! If you don’t succumb to me, I will convince you by force!”–Ye Feng!

Abandoned at birth in a humble stable, Shirone was raised by commoners—but he was anything but ordinary. Blessed with remarkable insight, he taught himself to read at a young age. A fateful visit to the city introduced him to the wonders of magic, igniting an unshakable dream of becoming a mage. Yet, beneath the city's dazzling facade lurked a ruthless social hierarchy, where power and privilege crushed those who dared to rise above their station. As Shirone uncovers the world's darkest secrets before even coming of age, one question remains—can he defy fate and claim his destiny as a mage in a world determined to keep him down?

The pond fish crossed.
Dressed as the only daughter of the once beautiful city master of Baicheng, now the male protagonist is going to be his wife.
There are appalling criminal records such as poisoning the heroine, assassinating the villain Bai Yueguang, and humiliating the flawed and sick villain.
In the opening situation of this hell mode, the first task released by the portable system is: – Save the world.
Chi Yu said solemnly: “It seems that my life is to be a hero of salvation. The road is long and long, and I will search up and down!”
More than ten minutes after taking the oath, she was crushed by the villain, the Great Demon King.
…
Chiyu: “???”
To fuck me on purpose? Is such a difficult copy still necessary? Is the garbage system thinking about P eating!
“I’m dead, and the whole text is finished and sprinkled.”
System: “No, you can revive infinitely until you complete the mission of saving the world.”
…
After half a month.
Chi Yu met the villain, the great devil again, and was pierced through his chest with a sword.
Two more months.
He was held in the arms of the villain, the great devil, and used as a shield for human flesh.
Chiyu: “…the mouth is fragrant.”
Five years later.
Chi Yu, who endured humiliation and was disabled and determined, successfully revitalized the love line of the original hero and heroine CP, which rekindled his fighting spirit, suppressed the villain, and saved the world.
After the incident, the clothes went away, and he hid himself deeply in the name, and “died” in the war.
…
However, her “death” collapsed across the board.
The Great Demon King ran wild and slaughtered the world.
System: “…We don’t know what went wrong, let’s do it again, shall we?”
Chiyu: “@#￥ system, you don’t have a mother.”

PS: Don’t look at the brutality of the copywriting, this article is 1v1, the love line is sweet and petty without abuse, the plot is Su Shuang sand sculpture (special settings, except for a little bit of abuse of the heroine)
The male protagonist does not have Bai Yueguang. The first generation only likes to do things, and the second generation only likes Chiyu.
