Rakuin no Monshou - Volume 3, Chapter 7: Sword’s Engraving

After dying a pathetic death as an overworked office drone, I woke up reincarnated as Archer—the bastard prince of the Brutish Empire.My existence is a royal secret as My father, the King, would rather pretend I don't exist. My half siblings get royal treatment while I'm hidden away like a dirty secret.But I have a secret of my own. I was OP.By age two, I realized monsters flee from my stupidly OP mana. By age ten my mana could level cities—if I dare to unleash it.When my half-sister is kidnapped by the demon king, I finally decided to step out of hiding to become the strongest in this new world.

Choi Hyun-seok, a heavyweight champion of the biggest mixed martial arts league on Earth and the one who was called the strongest had died.Afterwards, he was granted new life as a hero in another world.‘Wealth! Honor! Endless beauties at your fingertips!’With thoughts of such a dazzling future, the first thing that he saw when he came to this new world was a towering ox monster.The monster, who was the commander of the demon army, asked.“Hero? You’re saying you’re the hero?”“Uh…I think…?”And so, that was the start of hell.

Su Yun came to a comprehensive world that was about to collapse due to a mysterious recovery, but he didn’t panic at all.

Because, he can edit the stories of the two-dimensional girls and broadcast them publicly, and gain enough prestige by publicly executing the girls, and then he can…

So…

“Artoria, I am your previous life, King Arthur!” Su Yun, who was in the form of a dumb haired king, looked at Artoria, a foreign student with a bewildered face, and said valiantly.

“The evil spirit, that’s me, that’s you! Tokisaki Kusan!” Su Yun, who was transformed into the elf of time, stood in front of the stunned Tokisaki Kusan, with a seductive smile on his face.

“Balzebu, the power of thunder is my power, and my shape is also the power you should have. Now, try to take out the power that belongs to you from your body! It’s called – Dream One Heart!” After listening to General Thunder’s words, Balzeb subconsciously stretched his right hand to his chest.

Morgan Le Fay, Tamamo Mae, Miyamoto Musashi, Yae Kamiko…

One after another, mortal girls who had no power before, all showed their extraordinary side to the world under Su Yun’s bad taste.

So, people really think that they do have extraordinary power, and therefore, they have really gained extraordinary power.

The world has been completely changed because of this, and the mysterious history that human beings cannot overcome is rewritten!
