Ultimate Power

The outcome of the clash between the Kunai and the ice blade was completely unexpected by Sasuke.

The instant the two collided, the Ice Release Nature Transformation Chakra attached to the ice blade was transmitted, rapidly lowering the temperature of the Kunai to an extremely low level, causing its toughness to decrease drastically in an instant. Then, Sasuke was surprised to find that after the ice blade and Kunai in a standoff for a second, the ice blade shattered the Kunai into a pile of iron shards, just like cutting glass!

He instinctively jumped back a large step, only then realizing that it Kunai n't Kimimaro had cut him, but his teammate Sakura, who obviously wouldn't actually hit him.

The girl covered her mouth, squinted her eyes, and laughed, "Why are you reacting so strongly? Were you scared?"

Sasuke shook his head, not Kunai that Kimimaro had used his bone sword to cut through his kunai, nearly seriously injuring him.

He said, still shaken, "It's nothing, I just found it strange."

Sasuke a brief explanation.

He had just noticed the abnormality of the ice blade and poured a large amount of Chakra into the Kunai to enhance its strength, but it was to no avail. After all, at that temperature, the strength of steel was not much stronger than that of tofu, so no matter how much Chakra he added, it was impossible to compete with the hardness of an ice blade with a Mohs hardness of 7 or even 8.

Comparing steel to tofu is not an exaggeration. In fact, when the temperature reaches below -200 degrees Celsius, ordinary steel becomes more brittle than a potato chip!

For Sakura Haruno, who can unleash the full potential of Ice Release Nature Transformation, this temperature only requires a slight increase in Chakra consumption...

"So this is your 'cold and crisp' technique, isn't it?" Sasuke shook his hand, the Kunai's chill reaching his palm, making it numb.

"Hmm." Sakura nodded. This is what is meant by the low-temperature brittleness of metals.

In principle, the yield strength of some metals—that is, the limit of the force that the metal tries to return to its original shape when you gently bend it—increases sharply as the temperature decreases, while the fracture strength does not change much as the temperature decreases.

This means that when the temperature drops to a certain critical point, the yield strength increases to a level higher than the fracture strength, so that when a collision occurs, the metal breaks before it deforms, much like glass; this is what is known as brittleness.

"It's not just metals; in fact, almost all materials lose toughness at low temperatures," Sakura added.

Sasuke pinched his cuff; he had accidentally brushed against an ice blade there, and it was now hard and brittle. With just a gentle pinch, it shattered into pieces.

"So if you unleash the full power of your Ice Release, the effect will be quite considerable, right?" He rubbed the fragments of his sleeve with his hand, frowning as he said, "When facing Ice Release, you have to fight with extreme caution. Not only can you get frostbite if you're not careful, but your weapons and equipment will also become extremely fragile if they come into contact with your Ice Release Chakra. This is especially true for close-combat ninjas; their weapons can easily break suddenly, and then you can trick them into death..."

"Tsk, Ice Release is really insidious!" The Sharingan boy finally concluded. Only now did Sasuke realize that he was the first one to be tricked.

Sakura Haruno smiled gently.

While she prioritizes strong direct combat capabilities, occasionally using underhanded tactics against enemies can be a welcome change of pace, such as her Ice Clone and Ice Dart Explosion Technique.

Especially now that the Yuki Clan has gradually disappeared into the tides of history, most contemporary ninjas lack experience in fighting Ice Release ninjas and may not even know that Ice Release have such an effect.

As for its effectiveness, at least in battles at the level of Kimimaro and Sasuke, it can still produce remarkable results.

Of course, Sakura's goal is to Kage Level, but against enemies of that caliber, this is probably just child's play...

Just like when she used Swallow Snow Storm to cast the Demonic Mirroring Ice Crystals, she focused too much on details, which was too amateurish and not necessarily effective.

It's hard to imagine that someone like Orochimaru Jiraiya would be flustered and helpless because their weapon suddenly malfunctions.

The truly grand approach would be to create some sophisticated and effective Ninjutsu, just like using Frost Ice Burial to cover the surface of the Demonic Mirroring Ice Crystals.

For example, could we learn from Sasuke's Chidori Battle Suit and create a Frost Battle Suit?

This isn't difficult, especially since she already possesses an Ice Release Armor Ninjutsu that mimics the armor of the Land of Snow. She just needs to modify it, adding the Nature Transformation of Ice Release techniques...

This Ninjutsu could already be used in actual combat, but unfortunately it doesn't quite fit well with the Demonic Mirroring Ice Crystals for the time being, because this kind of armor somewhat hinders her movements and affects the Demonic Mirroring Ice Crystals's high-speed combat tactics.

The technique was never useful when dealing with the Sound Four and Kimimaro: for the former, it was unnecessary to use the Ninjutsu against the Sound Four; for the latter, wearing the armor slightly affected her speed in that high-speed combat, and this slight difference was a fatal flaw in that battle of insane Body Flicker Technique.

To integrate the ice armor into her tactical system, it needs to be significantly modified, changing it from a full-coverage type to a focused defense. All changes must be based on the principle that the armor does not affect her movement at all, since the ice armor is a physical block of ice, while the Lightning Release Cloak is just a purely energy-based defensive Ninjutsu.

Given Sakura Haruno's personality, Frostbite Clothes is certainly not the end of her Ice Release; there is still much to explore in terms of low and ultra-low temperatures.

For example, when the temperature is lowered to below -100 degrees Celsius, the air will liquefy or even solidify into liquids and solids, forming liquid nitrogen, liquid oxygen, etc. In a confined environment, this tactic can rapidly reduce air density, causing the enemy to suffocate...

Further down, one can discover Bose -Einstein condensation phenomena such as superconductivity and superfluidity.

Until the temperature is lowered to near absolute zero, one can access what may be the most massive energy source in the universe: vacuum zero-point energy.

This energy contains one hundred trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion (100 million) joules per cubic meter of space.

A simple calculation reveals that the space occupied by Sakura Haruno contains enough spatial energy to burn the entire Hokage planet three billion... billion (900 million) times!

That being said, in the Hokage world, she doesn't seem to be able to use such a massive amount of energy.

On the contrary, the ultimate power of Water Release is very suitable for her to crush all Ninjutsu and ninjas. Presumably, once such energy is unleashed, even the Sage of Six Paths would not be its match.

Moreover, she knew far more about that kind of energy than she could about vacuum zero point...

In fact, she had been thinking about this matter a lot while recovering from her injury recently.

That is... the so-called nuclear fusion energy.
