Half a month later, in the Flower Field on the King's Plateau.
Werther checked his left arm. It had healed remarkably well.
He flexed it hard, and with a crack, the plaster around his arm shattered.
Werther moved his left arm and nodded in satisfaction. It had recovered nicely. That Doctor might have been timid, but his medical skills were excellent.
It was four in the morning, and dawn had only just begun to break. Werther was alone in the Flower Field.
"Then it's time to try developing a new Sword Technique."
Werther stood still with a sword in one hand. A breeze swept through the sunflowers around him, setting great swaths of them swaying.
This time, Werther intended to bring together the strengths of every Sword Technique he had used before.
First was Sky-Splitting Sword: One Line.
The technique was unfinished. Werther had come up with it on the spur of the moment during his fight with Aokiji.
He had not been particularly strong back then. If Aokiji had not been protecting Vegapunk, he might well have stopped Werther from escaping.
Sky-Splitting Sword: One Line could shatter a vast stretch of space. Unfortunately, that was about all it did. It looked impressive, but it was practically useless.
Werther's original idea had been to trap an enemy using the shattered space. He had understood too little about space at the time, though, and the attempt had failed.
Werther had kept the idea of trapping an enemy with shattered space in mind.
Secret Sword Tsubame Gaeshi, on the other hand, struck three times in the same instant. Its strength was its extraordinary speed.
Werther made a note of that strength too, intending to work it into his new Sword Technique.
Black Armament Sword: Extreme Blade combined lightning, Armament Haki, and Swordsmanship.
