Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e - Volume 17, Chapter 3: Intro - Still, I must

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.

The salaryman who had a dream of becoming a CEO has finally succeeded.

However…

There was no one. No one was around to celebrate his success. Then on his first day of work, news of the death of a former colleague that he had laid off came. Additionally, his family left him, who was only concerned about the company.

The life he thought was right crumbled right in front of him. Where the heck did it all go wrong? Then, another opportunity came for Han Yoo-hyun, who had plunged down into despair.

This time, for sure. He was going to live properly. He was going to change it all with his whole being. The new life that Han Yoo-hyun was creating.

That valued life that will outshine any other is unfolding now!

After nine years of traveling with her parents, Long Shiyan’s family encountered a group of bandits. Although her parents died, Long Shiyan was able to escape from them with the help of a system. From it, she learned that she was stuck inside the world of a harem novel! In order to revive her parents, Long Shiyan must prevent the protagonist of the original novel, Long Aotian, from capturing wives and attaining a harem. Otherwise, the world would end!
