I'm a Security Guard. Unifying the World Seems Perfectly Reasonable

After arriving in this parallel world,

Song Qing is very fond of his life here.

Ever since he was bound to a ridiculous Comeback System, he can snap back at anyone who annoys him!

And he gets rewards for doing it. Tell me, isn't that infuriating?

But then he discovers that Lin Xuejiao, from the factory's third workshop, has a System too!

It's an erotic succubus System, unsuitable for children.

And it can even complement his own.

This is a tough one.

His body can't take it!

Someone, please save me!
