I'm Just Playing a Game, and Everyone Calls Me One Piece.

[Easy+Weidihua+Invincible+Pretending to be a pig and eating a tiger+Multiple women+Traveling to the past to make up for regrets] Monkey-D-Zhang Feng, who traveled through time and became Garp's nephew, had ordinary talent, so under Garp's care he entered the logistics department of the Navy Headquarters to do safe and easy paperwork. When he was bored, Zhang Feng unexpectedly discovered that he could imagine an extremely realistic pirate life simulation game just by closing his eyes. Just because he was bored at work, Zhang Feng fished at the Navy Headquarters every day and played this extremely realistic simulation game that he had "dreamed up". In the first simulation, Zhang Feng became a pirate swordsman on the Grand Line. He accidentally entered the Honeycomb Island, the headquarters of the Rocks Pirates, and participated in the hunting game among pirates. In the end, Zhang Feng suppressed the young Kaido with his powerful strength, and left a scar on Kaido's body that would be regarded as a shadow for the rest of his life, and he became a strong man recruited by Rocks. The second simulation... After countless game simulations, Zhang Feng finally cleared this pirate life simulation game. Just when he was lamenting the happy time this game had brought him over the years, the war on top happened to start. As a logistics unit, Zhang Feng was also assigned to the battlefield due to the lack of manpower for the decisive battle. Who would have known that when the live phone camera turned to Zhang Feng, Whitebeard, the Emperors of the Sea, the Shichibukai, the big pirates who escaped from prison, and all the big pirates around the world all exclaimed in unison. "The greatest pirate king in the world, Zhang Feng, appears!"
