The Navy had never underestimated the White Wolf Pirates.
If the Navy had truly underestimated them, it wouldn't have sent a Marine Admiral and an Admiral candidate—two Admiral-level fighters—to deal with them.
In theory, two Admiral-level fighters were enough to suppress any enemy in the world. No one could gain an advantage against two of them at once.
Let alone Mongge, whose strength had only been enough to fight Scarlet Snake Rona to a draw, another Admiral-level fighter.
But the Navy hadn't expected this.
In just three months, Mongge's physical condition had improved further from when he fought Rona. He had fully recovered to his peak—and even surpassed it.
At the same time, his Conqueror's Haki had improved through his battles with Rona and Harald, then grown stronger still with the system's help.
Combat was a contest of will.
Even without using Conqueror's Haki, as long as he could overpower his opponent in spirit, he could fight at one hundred and twenty percent of his strength!
And then there was his three seconds of Future Sight.
Mongge could now say he had firmly established himself in the Admiral-level realm. Enemies who had only just reached that level stood no chance against him.
That was, as long as he was fighting one-on-one.
"Hahaha, Mongge, is that all you've got?"
Seeing Mongge get sent flying hundreds of meters by his and Kong's combined assault, Sengoku burst out laughing. What if Mongge had reached the same level as him? Facing two Admiral-level fighters at once, even Sengoku at his peak couldn't win!
Mongge looked a little worse for wear. In a one-on-one fight, he could overpower either Sengoku or Kong, but against both at once, the tide had turned completely.
That was only because he'd seized the initiative earlier and worn Sengoku down.
