People are sailing: Invited to go to sea by sister Zhou

Yuan Yi traveled to the world of One Piece, but he has never seen One Piece
Fortunately, I got the Hawkeye Mihawk template and came to Koshiro's Kendo Hall to practice
Just when Koshiro had nothing to teach, the gymnasium ushered in sister Zhou who also came from time travel.
Looking at the kendo gym in front of her, Miss Zhou immediately saw Yuanyi with outstanding temperament and invited him to go to sea together.
For a while, the pirate world and the real world were messed up
Warring States: What's going on in the East China Sea? Why did such a terrifying pirate appear again? !
Mihawk: An interesting swordsman, looking forward to meeting us!
Countless netizens: "Fuck, this Koshiro is too good, how come the disciples he taught are better than each other?"
"And why does this Genichi not recite moves when he kills people?"...
