Traveling through the pirate world, Bai Lan opened his eyes to the difficulty of hell - bounty orders were plastered all over the streets, behind him was the demon-slaying order that was about to be launched, and five lieutenant generals were rushing towards him like crazy!
He didn't have a Devil Fruit, only a piece of iron, and the logbook in his mind belonging to "the world's greatest swordsman". Every time you arrive at an island, a page of the log is unlocked; every time you witness a storm, your swordsmanship becomes better.
When the first sword was struck, the navy headquarters alarm sounded wildly. From cutting steel to listening to the breathing of all things, from pointing the sword at the four emperors to defeating the generals, there will soon be only one legend left in this sea: If you want to challenge that man, first ask if his sword will answer!
