Fire Release: Grand Flame Sun Wheel!

The moment Kakashi finished speaking, he raised his hand.

The sky filled with the fire rain of Morning Peacock, and the air cannonballs generated by Kai's full-force punches in his Gate of View state, carrying terrifying impact and high temperature, all converged towards Kou's fingertips!

Not only the fire rain from Morning Peacock, but also the residual high temperature after the collision between the Dragon Flame Song Technique and Morning Peacock, and the ever-increasing temperature after the surrounding area was repeatedly scorched by two rounds of Fire Release,

At this moment, all of them converged on the tips of their fingers, reaching out to tap!

The surrounding temperature plummeted at that moment!

Even the air exhaled by Kakashi and Guy condensed into white frost.

A thin layer of frost had even formed on the ground of the dirt road.

All the heat around us was flowing in the same direction at that moment—towards the fingertips of the tapping fingers.

Kai stared in shock at the scene before him, instinctively glancing at Kakashi beside him, and couldn't help but ask:

"W-what... Kakashi, what's going on?!"

Kakashi didn't answer Guy's question; his eyes were also filled with deep confusion.

He stared intently at Koto in front of him, his Sharingan in his left eye spinning wildly as he focused on the ball of fire at Koto's fingertip that was constantly gathering a massive amount of Chakra.

The lingering Fire Release Chakra, the fire rain from Morning Peacock, and even the residual heat from the Dragon Flame Song Technique had just spread through the air...

All of these formed a visible Uzumaki of heat centered on the fingertips of the person tapping.

Kakashi took it all in, and the three Tomo in his left eye suddenly paused, a look of realization flashing across his eyes.

"So... that's how it is."

Kai looked at Kakashi in front of him without saying a word, quietly waiting for him to speak next.

"Knocking on him... he's been laying the groundwork for this technique ever since Dragon Flame Song Technique."

Kakashi looked at Guy beside him and explained the information he had just analyzed in a very fast voice:

"When a flame burns, the surrounding air is heated rapidly. As the hot air expands and becomes lighter, it rises quickly, creating a temporary low-pressure zone directly below the flame."

The relatively cooler air in the surrounding area will be driven by the pressure difference to rush towards this low-pressure center from all sides.

The airflow will then carry the dispersed flames and heat back towards the core, high-temperature area.

The more concentrated the heat, the greater the air pressure difference; the greater the air pressure difference, the faster the air flows; and the faster the air flows... the more concentrated the heat becomes!

Kakashi continued in a serious tone:

"What he did was to condense the fire-attribute Chakra at his fingertips, using that high-density core as the gravitational anchor point for the entire cycle."

He forcibly absorbed all the surrounding heat—whether it was the Fire Release he had just unleashed or the high-temperature fire rain without Chakra generated by Morning Peacock.

Then... it converges into a high-density heat source that can be redeployed!

Kai looked at Kakashi with a blank expression, clearly not understanding Kakashi's knowledgeable explanation.

Simply put...

Kakashi took a deep breath and held his White Fang horizontally in front of him again:

"The technique that Kou unleashed can be used by all high-temperature Ninjutsu."

Even the Morning Peacock, which existed solely as a physical flame without Chakra, was completely absorbed into his own power.

To enhance his next attack!

Kakashi, seeing the sudden realization in Guy's eyes, said in a serious tone:

"Kai, be careful!"

Next, we will face an extremely powerful S-rank Ninjutsu that can almost completely counter all Fire Release Ninjutsu!

Ahead, listening to Kakashi's professional explanation, a faint smile appeared on his face.

"To see through my Fire Release Ninjutsu, which I spent years developing, in such a short time... I must say, as expected of you, Kakashi."

He pointed his fingertips in the direction of Kakashi and Guy, his tone full of sincere admiration.

He stared at Kakashi's Sharingan, which was spinning rapidly, and murmured to himself:

"However... it's clear they're the same thing."

Whether or not they can handle it is another matter entirely.

At the tip of his fingertips, the crimson flame had reached its peak!

It is not shaped like a flame, it has no tongue of fire, no outer flame, it is just a reddish "dot".

The air around it was distorting wildly to a degree visible to the naked eye.

Centered on Koko, the temperature around him rose rapidly, creating a stark contrast with the environment where Kakashi and Guy were located, which had been deprived of heat and still had a thin layer of frost remaining!

As Kou felt the terrifying heat accumulating at his fingertips, a deep sense of solemnity crept into his gaze as he looked at Kakashi and Guy.

This move was the strongest attack method he developed on his own before he awakened the Mangekyo, relying on his more than ten years of accumulation in the Uchiha Clan, plus Madara's research "legacy" on Fire Release!

It was both a means to defend against Ninja World, the most formidable... uh, no, the strongest physical attack in the Amaterasu, and also proof that he was finally able to reach the Kage Level!

Kouchi stared intently at Kakashi and Guy ahead, muttering to himself:

"Savor this, my strongest... Fire Release Ninjutsu!"

Before he could finish speaking, the quietly spinning crimson dot at his fingertips suddenly exploded!

A giant flame cannon, over five meters high and several meters wide, roared out from Kou's fingertips!

That wasn't ordinary Fire Release; it was a combination of all the heat absorbed from the entire battlefield, plus the fire-attribute Chakra that Kotetsu had refined himself.

A pure thermal shock wave released in a directed manner in the form of ultra-high pressure in an instant!

The cannon was incredibly fast, carrying a tremendous impact that would plow a deep, scorched trench in the ground, as it blasted fiercely towards Kakashi and Guy!

The dirt roads along the way began to melt before the flamethrowers even touched the ground, and countless tiny glass crystals exploded on the surface of the soil and rocks.

It is a product formed by being instantly heated to thousands of degrees Celsius and then rapidly cooled.

Kou stared directly at Kakashi and Guy with his Three Tomoe Sharingan and said in a deep voice:

"Fire Release: Great Flame - Sun Wheel!!"
