A human from Earth is thrust into the [Hunter x Hunter] world, becoming the Zoldyck family’s defiant, red-eyed prodigy. They call me a genius and the rightful heir, but I say that’s Killua’s burden to bear.Armed with crimson eyes, and a subtle yet powerful system, I’ll rewrite destiny, upend the world, and embrace the chaos with a wicked grin.

The most famous deed of this princess was her words to her younger brother Liu Ziye.

When he became emperor, she told him, “Although your highness and I are of different sexes, we are the children of the same father. Why can you sleep with so many different women, while I must be only with my husband? This is so unfair!”

And after the Emperor Liu Ziye heard his elder sister’s words, he ridiculously thought it made sense. So he immediately corrected his “wrong ways” and painstakingly selected thirty handsome youths for her to enjoy.

Chu Yu awoke in the princess’s body and realized that she had obtained a male harem of three thousand; should she take just one to drink, or keep all of them?

Du Jiuyuan lay in a grave of love for three years. Finally, her heart was as dead as ashes, she gave up on finding love and decided to go down a career path of a strong woman. But what was going on with her ex-husband? He used to be someone whom she would only see once every four to five months. Why was he appearing in front of her now and then? When she talked to others about collaboration, he would coax her from behind. “Yuan Yuan, this person is unreliable. Let me invest in her for you, okay?”

When she got into conflict with others, he would support her from behind. “Yuan Yuan, don’t be afraid. Your husband is Ji Jinchen. Don’t worry about her.” Du Jiuyuan was speechless. “…” Please take note that it was her ex-husband who divorced her. One day, when a male colleague sent her home after a meal, she was seen by Ji Jinchen. The man blocked her at the foot of the wall and questioned her in a low voice. “Don’t be with others, otherwise… I will lose my mind.

Later, Du Jiuyuan rose to the top of her career and attracted countless suitors. One such suitor gave her a bouquet of roses and the next day, her office became a sea of flowers. Some suitors gave her desserts that could only be bought after queuing up. The day after that, her office would be flooded with desserts. Some suitors gave her a pet… Du Jiuyuan went crazy. “Ji Jinchen, if you dare to give me a house full of pets, I will fight it out with you!”

Ji Jinchen said, “Jiuyuan, forgive me for being stupid and not seeing your grievances, but you have to believe that from the moment I married you, I never thought of getting a divorce. Du Jiuyuan: I thought that the man I loved for seven years was a stone that couldn’t be covered up, but then I realized what kind of fiery heart was hidden in this stone.”
