There Are Only Swordsmen on the Pirate Ship

I was watching anime, I was transported through time, and an unreliable system actually gave me a sword manual! ! ! "Sword Manual" Chapter 1: If you want to practice this skill, you must first retreat from the palace. ······ The last chapter: Even if the palace is not successful, it may not be successful. There is no woman in my heart, so I draw my sword to the God of Nature. Look at the young man, fighting in the era of great pirates, shaking the world.
