One Piece: Dream of Immortality - Chapter 24: A Remedy for Weakness

Betrayed and left for dead, a soldier awakens in a world of knights and magic—but only one path is open to him.Hayden was once an elite soldier whose abilities were enhanced by the Ocularis Lens, a highly advanced mechanical eye technology.In this world that was filled with danger, Aura—a sacred energy that enhances the body and infuses weapons—is the mark of a true Knight, while magic is wielded by those born with the gift of sensing Mana.Hayden, however, is no mage. He doesn't have the ability to sense Mana, leaving him with only one option in order to survive: to become a Knight starting from a Knight's Academy!

Demons in Academy of Light are described as vile, dark, cruel, evil, impure, and a whole lot of other things. At least, that’s how they’re portrayed in the game—a sacred land where demons and dark energies aren’t supposed to exist. That’s how it was supposed to be... So what the hell am I supposed to do now? Thanks to my rotten luck, my soul ended up possessing the lowest-ranking demon, the one who dies at the very beginning of the story... I’m screwed! I have no other options left... If I want to survive, I have to kill the protagonist.

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.
