Before, since he had never been able to confirm whether the secret of the "King's Fist" was real, Mousse had not given it much thought. But now that he knew it was genuine, his extraordinarily clever mind immediately began racing at high speed.
Mousse quickly thought of a problem that neither Fourth Brother nor Mother had noticed. "According to that king, the strength of the 'King's Fist' lies in the extra Armament Haki it accumulates. But because it takes advantage of that extra Haki, the Haki in one's body cannot be converted into Armament Haki too quickly; it has to wait for the former to recover. That is why the 'King's Fist' needs such a long preparation time. But does it absolutely have to take that advantage?"
According to what Cracker had said before, if he attacked at full power—converting the Haki within his body into Armament Haki and releasing it at the fastest possible speed—his Haki would be completely drained in just a few dozen seconds. And the stronger the Armament Haki, the faster it would be consumed.
In other words, if they gave up that "advantage" and converted the Haki within their bodies into Armament Haki as quickly as possible, releasing it outward and accumulating it using the charging technique of the "King's Fist," they could gather power equal to "Four Apples" in just a few dozen seconds, or even less!
That was twice as powerful as the "Three Apples" Charlotte Linlin had used just now!
Of course, exhausting one's Haki in battle would put oneself in danger, and the upper limit was only "Four Apples." That was not quite enough for the "King's Fist," which had originally been meant for challenging opponents above one's level. So Elizabello II not mentioning it before did not necessarily mean he
