Naruto System in One Piece - Chapter 421

After rebirth, she, who used to be a top international spy, becomes the eldest daughter of the Fengs, a fat girl who is ugly and foolish in the eyes of the ordinary people.
Mastering Royal 18 Saber Moves and Purgatory 9 Palms, she rose to fame with the martial arts of Demon Cook.
Upon an imperial edict, she was ennobled as the wife of Lord Cen, and then suffered various intrigues and plots…
She proved herself to be a real overmatch and a true genius to the world…

This is the story of a young slave gladiator in an underground arena. He doesn’t know about his past or how he got to where he is, only that his name is Aegir, and that he is strong.

Ni Yang, a modern businesswoman, is reborn in her seventeenth year.

The year is 1983.

In an era that favors boys over girls, Ni Yang revises her tragic fate from her previous life, skirmishes in the mall, and overcomes the most challenging obstacles, achieving success step by step – a radiant progress.

Observe how Ni Yang, with her petite but capable hands, overturns her fate from an ordinary rural girl to become the richest woman of her time.

However, in the process of building her wealth, Ni Yang inadvertently attracts the attention of a mysterious magnate.

So, the aloof and mysterious magnate in the eyes of outsiders transforms into a devoted husband, becoming an outright ‘wife slave’.

From then on, ‘wife is Heaven’, ‘serving wife is duty’.
