Within a Hollow Heart - Chapter 138: Volume 2, : "The Rift Opens"

The bad news, at least for me, is that I died. The good news is that I was reincarnated into someone else's body who lives in a cult full of beautiful women... but this cult forbids love. Well, one can't have all the good things. I thought I was safe until the worst happened. A system appeared that told me that I would die if a girl didn't accept my confession within a month... I have to get out of that cult now.Every 10 days I upload 15 chapters at once on Patreon.

When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

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!”

As soon as Qin Yao opened her eyes, she was transported into the body of an ancient peasant woman from the end of the world.

There are four stepsons at home waiting to be fed.

A bastard who has nothing but good looks is jumping up and down.

The family lives in a thatched hut with not even a grain of rice in the jar. The whole family is as skinny as refugees.

Forget it, there are still people coming to ask for debts!

Qin Yao was angry from the bottom of her heart and kicked her bastard husband out, “Brother who wants to pay debts, please just beat him to death!”

Four stepsons:! ! !

The world is clean, Qin Yao rolls up her sleeves and makes a fortune.

She is great at hunting, carrying bags, and killing horse thieves.

It is this kind of land, facing the loess and turning its back to the sky. Even the top strong men who have been struggling in the apocalypse wave their hands repeatedly: I can’t stand it! I really can’t stand it!

Qin Yao scratched his head: In ancient times when agricultural taxes were extremely high, how could we stop farming?

At this time, the lazy husband who was sent to die (twisted and crawled) (struggled to stand up) (screamed and roared): Wife! I think I can still save a little more!
