Book Recommendation ~ Pirate: Sword Demon Admiral

I recommend a friend's new work in the same genre: "Pirate: Sword Demon Admiral."

The protagonist was also from League of Legends—a Darkin Sword Demon equipped with a Guardian Angel. He was absurdly powerful.

At present, the protagonist had the old version of the Sword Demon's skills.

Come to think of it, a Silver scrub like me couldn't play the new version of the Sword Demon at all. ==
