I hit the button for a million years and before I knew it I was the strongest

Briefly about I hit the button for a million years and before I knew it I was the strongest manga:

Allen, a failed fencer, bet the star of the academy that he would leave the walls of his home alma mater. But only if he lost another duel. Well, it was time to keep his word. But life brought an unexpected surprise in the person of the recluse. He not only offered to train Allen, but to do so for a million years. Was that possible? You can’t judge a manga by just one chapter. Maybe the next 3 chapters will reveal the hero and his inner world.

Read I hit the button for a million years and before I knew it I was the strongest Manga.

But if you’ve read the novella. I think there was an adaptation of this work. Because I’ve seen such an anime before. There the hero had a sister and had a harem of sorts. At the end of the anime he marries a red-haired princess. She was his slave because she lost in a sword duel.

Bless you iskai adventures for alerting me to such a beautiful piece of work. I already wanted to start reading it. But when I saw that this manga is Japanese. I don’t know what’s wrong with them and why all manga in this genre are like one another. I decided to see what other people thought and how cool it would be. I’ll tell you right away after reading this spoiler, there’s a good chance you’ll read this work. I apologize in advance to the translator and sympathize at the same time. If you want to save your psyche, read this work.
