Yuu took a deep breath. This battle had been somewhat taxing.
But it was no big deal.
Hawk Eyes Mihawk's strength was indeed formidable. As a swordsman, he had actually forced Yuu to use forty percent of his power. In the Pirate World, he could be considered a worthy opponent.
"Ding! Congratulations, Master, for defeating Hawk Eyes Mihawk and completing the mission.
Black Blade Shusui has advanced!
Congratulations, you have received a swordsmanship reward. Swordsmanship strength increased by 500."
As the system's voice fell silent, Yuu discovered that Black Blade Shusui had changed once more. The blade itself had become even purer.
Its sharpness had also increased considerably.
Yuu gave it a light swing.
Several sword qi slashed out directly.
"It can release sword qi automatically?" Yuu was somewhat surprised.
He had not used any sword qi at all. He had merely swung the blade casually to see how Black Blade Shusui had changed, yet it had automatically released sword qi. Even with a casual movement, it faintly felt as though it could split open space.
If even ordinary attacks could achieve this...
Then any casual strike would possess the power of Whitebeard's Tremor-Tremor Fruit to shatter space.
Although it had not yet reached that level, it was already enough to make Yuu happy. With this mission complete, the next mission would be to save Ace!
Yuu looked toward Ace on the Execution Platform.
Sengoku seemed to have summoned backup executioners.
Luffy had been watching the show the whole time, observing Yuu's battle with Hawk Eyes. Only now did he remember what mattered and hurried toward the Execution Platform.
"Do it! Do it! Execute Ace already!"
Sengoku immediately gave the order.
The two executioners brought their blades down.
Yuu used Conqueror's Haki, instantly knocking the two executioners unconscious.
Sengoku stared
