The Death Corps Becomes the Navy's Chief Instructor

[BLEACH × One Piece] [Original plot in the early stage, slight changes to the original plot in the later stage] [Slow update (extra slow)] The strongest Shinigami in the Soul Society accidentally traveled through time after death and became a traveling nuisance in the world of One Piece. A hundred years ago, he was just a dying soul that was about to disappear. The power was lost, and the beloved sword was called the world's weapon and was taken away by others. Even the spirit body was so weak that it fell asleep all year round. Until a kid with a straw hat appeared: "Who is talking!? Ghost??" A hundred years later, with half of his strength recovered, he embarked on a journey to find his beloved sword, and unexpectedly met many powerful men in the future. In order to prevent justice from rotting in this world, he joined the naval academy. After teaching a group of soldiers full of justice, he was recognized as the chief instructor of the navy. The world government is paying attention, but no one really knows the origin of this silent old man. Until the war on top. In front of the execution platform, the navy's bayonet was aimed at Fire Fist Ace. Garp clenched his fists, but couldn't move. A crack burned through the sky. The old man who had disappeared for a long time appeared on the battlefield, wearing a navy coat, with only one word behind him—— Total. "As of today, the Navy is independent. No longer affiliated with the World Government." "Our allegiance is only to this sea." That day, the world was shocked. But the story starts from the small village of Donghai many years ago.
