The Invasion Begins with Pirates

While playing a highly free game, Chu Wei was forced to travel to a world very similar to the game due to game bugs. However, for some reason, the world he was in seemed to be very close to the world of One Piece, so there were inexplicable disappearances of characters and invasions by foreign enemies. What is going on? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
