At this moment.
While the World Conscription at Marineford was in full swing.
The Land of Grass...
Was equally busy.
Since they had already said they would establish a navy, the Land of Grass naturally would not merely pay lip service to it.
Besides, the ninja's strength truly needed to be improved as well.
Ninja had enormous advantages, but their weaknesses were equally obvious!
Their ever-changing ninjutsu was certainly quite intimidating!
They were not afraid of seawater, could even control seawater to restrain Devil Fruit Users, and had versatile Sealing Jutsu, but once they faced a somewhat stronger Great Pirate, they might not even be able to break through their defenses!
Take Luffy right now...
Without using certain secret techniques, an ordinary jonin might genuinely be unable to defeat him now that he could use Gear Third!
And then there was a ninja's endurance... Compared to the powerful physiques and three types of Haki found at sea, ordinary ninja might not even touch their opponent before getting knocked out in one blow!
Setting aside those random navy men and pirates shouting "666" from the sidelines, the physiques of the navy and pirates on this sea were generally indeed stronger than those of ninja!
Especially since there were quite a few people across the sea who could use Haki!
Of course, that was not much of a problem!
What was the Land of Grass's ancestral craft?
Copying... Pfft, learning from others' strengths to counter them!
They just had to learn what others did well~
And now that the Land of Grass had established its own navy... they could simply keep learning.
The Land of Grass also had the Navy Six Powers.
Of course~
They had to be careful while learning the Navy Six Powers.
Especially the Navy Six Powers—Iron Body. How
