Pirate: I Open Eight Doors of Armor in the Navy

Lin Nuo opened his eyes and found that he was resurrected from the dead. One second ago, he was a genin in Konoha Village who had just learned the Eight Gate Dungeon. He reluctantly shed the last drop of his blood to protect his teammates during his first mission. The next second, he became a navy recruit in the world of One Piece. This world is more dangerous, with natural and man-made disasters happening all the time, and the strong destroying the world. And his biggest trump card - Eight Gate Dunjia, is a double-edged sword that burns life. The death in the previous life became a mark engraved in Lin Nuo's bones. So, he chose a different path. Those who can solve the problem with words will never take action; those who can win with tactics will never reveal their strength; those who can solve the enemy with six moves will never open the first door. "The Eight-door Dunjia is a trump card used to forcibly find a way out in a certain death situation, not a tool to show off." "In my plan, the enemy will always have only two forms - 'easily killed instantly' and 'temporarily unprovoked'." This is the story of a navy that is stable to the core, relying on intelligence, layout and hundreds of millions of trump cards, to quietly reach the top of the world in the chaotic era of great pirates.
