In Naruto: Reborn with a Chat Group - Chapter 163 - 161: Sasuke’s Awakening

A handsome man was hit and lost his memory for dangerous driving and saved by Lin Xiaomi. Since the day, the man just hung on in her house and refused to clear out. Also, from that day on, the only goal of Lin Xiaomi was to dislodge him!

The first person that Leng Yihuang saw after losing memory was Lin Xiaomi, who was a full-breasted beauty simple like an innocent child. She fascinated Leng Yihuang like a magnet. Since the day they met, his only thought was to f*ck her!

Of course, the winner is king, the loser needed to warm the bed… But after the night, the bastard just disappeared. Lin Xiaomi swore to God that she would hunt down that as*hole no matter where he was.

But when a bunch of guards with guns showed up and called Lin Xiaomi “Your Ladyship”, she was struck dumb with fear and astonishment. The man who walked out of a Rolls-Royce was just Leng Yihuang, who turned out to be the heir of a big shot…

A young boy, Asuma Haruto, is transferred to another world. Without having any means to return home, he has no choice but to live in this parallel universe.

Armed with only his knowledge of making soap, will Haruto be able to safely make a living here?

This is a story about how our protagonist creates his own business out of his hobby of making soap and then gradually manages his business and gets rich.

Qi Condensation. Foundation Establishment. Core Formation. In the current world, only these three realms are known to be achievable. Nascent Soul is but a legend and the realms above it lost to the the long river of time. The modern era is known as Cultivation Civilization, a balance of power and civility, excess and moderation. While cultivation remains a secret practice, it has long since exposed itself to the mundane world, quietly intertwined with each facet of society. While the world appears to be at peace, what lies underneath is a conflict between human, cultivator, and demon, brewing for ages and waiting to implode. Yet in the wake of humanity’s rapid industrialization, qi—and consequently cultivation—is dying.
