I Was a Swordsman in Ancient Japan

As the title indicates, the author intends to collect materials today and take a day off.

Maybe many readers will question it, thinking that the material is completely deceiving.

But I can pat my chest and assure everyone-it's really not a lie.

The author has been supplementing knowledge about sailing battleships since this morning. I thought that with the author's ingenuity, I could get a general idea of ​​sailing battleships in half a day, but I found out that the knowledge of ships is really profound... After reading the online information for a long time, I was in a fog .

So I decided to spend a whole day learning about sailing battleships.

There should be "ship enthusiasts" among my readers. Is there any documentary related to "Sailing Battleship" that you can recommend? It is best to be a kind of documentary that is quite friendly to beginners like me who can't even tell the difference between a cruiser and a destroyer, and focuses on the size and speed of the "sail battleship".
