One Piece: So What If I Sin, Lie, and Lust? I'm Still a Good Marine - Chapter 15: Germa’s Technology

I possessed the weakest character in my favorite game’s Hell Mode. I want to survive, but the way the main character is being controlled is atrocious.

It can’t be helped.

I have to stop the bad ending myself.

A magical ring and a mighty spirit inside the ring, coupled with a genius who lost his cultivation and got named worthless trash. That’s Xiao Yan, the poor genius. You think Xiao Yan got it bad? Well, you clearly have not met Jing Yan.

Jing Yan was once the shining star of the whole East City. However, his cultivation dropped because of the Universal Ring that was left to him by his dead grandfather. Without anything but the Universal Ring, he will once more rise towards the top and beyond!

He is Jing Yan, The Universal Sword God.
