Naruto System in One Piece - Chapter 60

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?

It has been six years since the country stopped admitting college students, and no one knows when the college entrance examination will resume. Su Xiaoxiao, who was an outstanding student, was now humiliated after not being able to attend university.

She was too high for the people in the village and too poor for the people in the city. Due to this, she became a “leftover girl.”

An educated youth said he was willing to try. When Father Su then asked the educated youth when he planned to marry his daughter, the educated youth said it was Su Xiaoxiao who took the initiative to pester him before agreeing to give it a try, and he wanted to go back to the city in the future and did not plan to marry a country girl.

Su Xiaoxiao couldn’t take this humiliation anymore and decided to jump into the river to commit suicide. This made her reputation become even worse. The matchmakers had to go around when they passed by the Su family’s house. Mother Su and Father Su were so angry that they almost rode a crane to death. They decided to marry their daughter in the city regardless of the dowry.

Han Cheng, who had lost his wife for a year, went back to the city to visit his sons on his vacation. His two sons, who were once white and chubby cubs, became skinny and gloomy after living with his teacher’s wife. He was so angry and immediately asked the matchmaker to go to the countryside and find him a match. The only requirement he asked for was, that she must be literate.

The matchmaker went to the Su family’s house, and there, Su Xiaoxiao, who came from the 21st century, didn’t raise any objections and accepted it.

However, the unreliable matchmaker actually invited another girl besides Su Xiaoxiao and arranged their dates at the same time.

Han Cheng asked Su Xiaoxiao, who looked like a good match for him: “Are you literate? Do you mind taking care of my two sons?”
