Destiny's Game* - Chapter 51: Acceptance or Death.

The more ruthless the Palace is, the more miserable the loser will end up—this he understands. But what he does not understand is, why the brother whom he lived together with peacefully in the past, would so heartlessly humiliate him today. Asking him to beg for mercy, asking him to succumb to his knees, and even… asking him to tactfully entertain him. “Yong Shan, ah, Yong Shan, as of today you are the one who qualifies to succeed as a Crown Prince, what exactly is it that you want?”

For the past 16 years, Yong Qi’s gaze was never set on him. Despite being twins with his younger brother, Yong Lin, Yong Qi has always been directing his smile and laughter towards Yong Lin, and to him, Yong Qi deliberately alienates him. He does not understand, they have the same features and looks, and he obviously is his brother too, but why won’t he be intimate with him… as if he is humiliating him. “Yong Qi, ah, Yong Qi, why won’t you understand, what I want is very simple…”

Liv Hamelsvoort, who bears the label of the ‘Fake Saintess’ and is the laughingstock of high society for her unrequited love for Duke Lartman. No one could understand her, but she likewise couldn’t understand them.“I’m in the middle of enduring the love of the gods.”There was a world that ordinary humans couldn’t dare to comprehend.“Who harmed my child?”“Does my child not exist in this world?”“I don’t need a world where the child I love doesn’t exist.”The moment the enormous things she had been bearing were revealed, Liv’s life finally began to change.“I will love you in any timeline, Your Grace.”Liv was content as long as she could continue loving. But if she wanted to protect that love, she had to change; the world was whispering that to her.

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.
