One Piece, ice and salt

Hi everybody :)

While I was reading a chapter of the famous manga One Piece, I came across a phenomenon that immediately reminded me of the article on the "ice and salt challenge" that I published recently. For the curious article is available here: Ice and salt challenge

I remind you of the main lines of this article:

We all know: salt + ice = melting ice
But the mixture of salt and ice also reduces paradoxically the temperature of the ice
Explanation: the salt ions want to be housed between the cohesion bonds of the ice (hydrogen bonds)
Destruction of these connections requires energy taken from ice in the form of heat so its temperature decreases

In One Piece

The story takes place at scan 321 of One Piece or even at episode 228 for the animated ones. During this episode the crew of the straw hat meets one of the three general of the navy: Aokiji. The latter possesses the powers of a fruit of the demon: it has the ability to control the ice.

A struggle ensued between the crew of Luffy and General Aokiji. The difference in level between the pirates and Aokiji is very quickly felt and the latter finally freezes parts of the body of certain crew members, including Sanji and Zorro,

These last two, real warriors of the seas, do not wait their doctor and decide to treat their frozen arms themselves by throwing themselves in the sea!

Here is a video of the fighting scene, Sanji, Zorro and Luffy are freezing at 5 min.

What is the problem ?

As we have seen in the article "ice and salt challenge", the salt applied to ice in contact with the skin causes severe burns. Our two pirates throw themselves into the sea of ??salt water, so if it is true that the ice will melt more quickly than with fresh water, severe burns should be visible on their arms. But let's not forget that our two pirates are tough to cook;)
