[Warning 18+ Hentai Novel]After his parents move overseas for work, Haruto, a 19-year-old boy, is sent to live with his grandfather in a quiet rural village of Japan. Far away from the city’s noise, he expects a boring, lonely life surrounded by rice fields and temples.But the countryside holds secrets—behind the modest smiles of the villagers are girls who burn with unspoken desire. From the widow next door who bathes naked by the river, to the shy schoolgirl working at the family inn, to the shrine maiden with a hidden craving for cock—Haruto’s arrival stirs a wave of lust in this quiet place.Soon, he finds himself entangled in nights of steamy encounters, sucking and licking pussy under the moonlight, feeling warm tits pressed against him, getting blowjobs in hidden barns, and filling tight, dripping cunts with his cock until they overflow.For Haruto, the countryside isn’t peaceful at all—it’s a paradise of naked bodies, moans echoing through the fields, and endless forbidden pleasure.

There was a mysterious old man who approached the failed swordsman with the “100 million years button”. A magic button which can achieve the same effect as training for 100 million years if you push it.

The failed swordsman who pushed the button had his doubts, but immediately felt tremendous power rising in his body. So he pushed the button many times.

However it was a cursed button. The moment it was pushed, he was confined to the 100 million years prison of time. The first 100 years were devoted solely to training. After 1000 years he had forgotten why he swung his sword. He stopped thinking completely after 10,000 years had passed. After 100 million years he became crippled and finally managed to return to the real world. At the same time losing all his memories from the past 100 million years, the only thing that remained were his sword techniques. “I can become stronger just by pressing the button!” or so he thought and pushed the button many times after that. Foolishly trapping himself in that 100 million years of hell each time.

As he continued this loop, he began to think “If I destroy this world, will I get out of here?” A few billion years later, he finally escaped from the loop.

This is the story of a failed swordsman trying to make a name for himself in the world.

'A self-centric Female Lead, lost-in-love Male Leads, and useless extras who will die. On top of it, this world will not be here for long because of that ancient threat. So, what should I do now?'What kind of world was a world of Female-Oriented Fantasy romance? One filled with tinted glass and roses? Life should have been easy here, right? Wrong! Layla had read this book before, and she knew what happened.“Those useless leads left this world in a shamble! I need to do something about it before it gets destroyed. If I am going to live here, I need to ensure this world stays alive long enough. Who has time for romance when the world will end soon?”Her goal was set, and her life was laid out. Layla was going to use whatever she could to secure her second life.Everyone was a useful piece from here on, and Layla used them well to achieve her end goal. This might be a world based on a fantasy romance, but she would ensure it would not repeat it's ending.______Note: It has a strong Female Protagonist as the MC. No romance, no harem, no yuri.

I was a failed experiment
