In a world with bloody and vast battlefields where several forces fought for supremacy; a young boy only known as number 2044, was kidnapped and trained to be an assassin by the enemy since he was a child. After much intensive training and struggling through life-threatening situations, he gained the name “Mukhyang”. But Mukhyang was never satisfied, he had an unfulfilled thirst for something, and that was the path of the sword! As Mukhyang was dissatisfied with his life as an assassin, he met his mentor ‘Yu Baek of the Hwan Sa Sword’ and his life changed forever. Will he be able to reach the pinnacle of martial arts?!

Fighting with geniuses as he climbs his way to the top!

Max-level internal arts, max-level external arts.

Jianghu, Murim’s famous and strongest, Cha Shin Hyeon.

I came back to Earth after reaching the peak of martial arts, but why has everything changed so much?

A world where monsters are coming out of dungeons, and hunters are leveling up via their status windows.

‘Start again from level one? That doesn’t phase me at all, since my martial arts are already at the max level.’

I’m not that kind of person.

I, Deon Hart, am a sickly person who vomits blood whenever I’m stressed.

However, at the same time, I’m Demon Arut, who has somehow been misunderstood and thought of as a strong person, and thereby feared by everyone.

“Demon Lord.”

That’s…
What they used to call me in my past life, before I became human.

The greatest martial family, Samion. Daven, a member of the Samion family, is a one-armed martial soldier without a right arm. Despite the ridicule and contempt he got for only having a left arm, he surpassed the direct line of the Samion family like a genius. However, he got betrayed by his family and parents in the end, thus meeting a poor end. But, he was reincarnated. “I have a right arm?” He had a new family tradition. A naturally gifted body. Experience from his past life. And the god Yulion with him as well. After his reincarnation, everything changed, and a new adventure started.

If the Grim Reaper calls your name three times, you will be taken to the underworld.

You bastard! I want to live longer!! Get lost!!!

After desperately eating the herb of immortality, I couldn’t believe it, but I survived.
When I realized this was real and opened my eyes, there were old geezers standing around me…!
Where am I…? Mount Wudang? The Wudang sect?! And what’s even worse, I’ve possessed the body of an errand boy. …This is nuts!!!
I… I am… the strongest… the absolute f**king strongest Heavenly Leader of the Evil sect, Hyeokryeon Mugang!
