The amiable looking patriarch is gazing at a stone monkey: “Wukong, what do you want to learn from me?” “It’s all up to master’s instruction.” The stone monkey respectfully replied: “As long as I will be able to beat up Tathagata, then it’s alright.” One hundred years later, the stone monkey defeated Tathagata and ascended the throne, becoming the Jade Emperor.

Crossing to One Piece world, he became Roger’s younger brother.

Before Wufu was reborn, she had no idea there was such a thing as rebirth. Only after her rebirth did she realize Heaven must have thought her previous life was too smooth, so it sent her to suffer in this ancient land where morality, decency, and the Female Precepts were held in high esteem, pitiful indeed! From being a master jade carver to having her soul transmigrate into a farm girl with a wretched background, she was bullied and humiliated. Even the bun-selling mother advised her that forbearance is gold? Bullshit! She could endure, but her other identity absolutely could not—robbers, swept away; insults to her mother, you're crippled... Wufu has a saying, for every insult and humiliation, I will repay a hundredfold. But what's with this one? He doesn't bully her; he only wants to sleep with her? And he even dares... to mount her? Well, a lord can endure, but Wufu cannot. Mount him back, life or death, a hundred years, neither owes the other anything!

The little handsome son-in-law passed through a world as waste material and the husband of a wealthy family. But because of his lacking aptitude, the wealthy family had driven him out. So he worked hard and found a more powerful family’s thighs to hold onto. Soon enough, he became the strongest son-in-law and husband in history.

In this world, it was impossible to practice martial arts. It was futile so he might as well take advantage of his wife’s thighs and maintain a comfortable and leisure lifestyle.

He’ll train his wife to become the strongest and best person in the world.

“Whoever dares to provoke me, let my wife kill you!”
