- Description from xbiquge

I fell into a game world out of nowhere with an instant kill skill.
And then somehow, I became a bigshot.

Xuan Yi was transported into the fictional world and became an elder of the Black Sword Sect! The moment he entered the world, he was at the Sea-Splitting Rank!

Enemy of the world, cursed by all, Kim Sungchul goes on a quest to prevent the ‘prophecy of the end’ from coming to pass.

But no matter how much he raised his strength, there were still some things he could not achieve with physical strength alone.

Resolving to obtain the power of magic, he goes into hiding to learn magic from his most hated of enemies, The Mages.
