Half a month later......

Inside a lush secluded forest.

Two children of about four or five years old sat opposite each other, their eyes closed, their hands pinching out strange handprints, and a faint light appeared around their bodies, apparently extracting chakra.

The time has entered from June to September, from the hot weather to the dry autumn season, the green leaves on the trees have not withered because of this, they are still green and lush, and only a few yellowing dead leaves occasionally fall.

After another hour, the two people facing each other stopped their manual movements, opened their eyes and looked at each other, and then reached out at the same time to pat the ground, and their bodies retreated ten meters back, distancing themselves from each other.

'Poof! ’

The sound of the knife being drawn out of the sheath sounded, and the two people in the field had already gone through countless trainings, and their footsteps did not stay in place, they drew out their sharp long knives and slashed towards each other!

'Bang! ’

The twin knives collided, and sparks flew everywhere.

The two quickly withdrew from the place after the blow, and once again opened a distance of dozens of meters to look at each other, their eyes and gaze staring closely ahead, and the long knife in their hands flashed with sharp light.

Uchiha's dark blue eyes flashed, his hands held the hilt of the sword, and his footsteps moved slightly, mobilizing the surging chakra in his body, and a trace of cyan blue light appeared.

The cutting sensation that represents the change in the nature of the wind attribute chakra is wrapped around the sharp blade, and before it can attack, it already brings a burst of wind tearing around it.

"Knife Technique, Ninja Method, Bitter Whirlwind Cutting!"

Uchiha Zang let out a cry, and the long knife in his hand that flashed with a cyan blue chakra light suddenly slashed out with a backhand, and the cyan blue whirlwind blade detached from the long knife, spinning rapidly in mid-air, and countless fallen leaves were swept away and torn apart.

"Humph!"

In the distance, Uchiha Izuna's face was slightly gloomy, feeling the tearing sensation coming from in front of him, and he snorted coldly, but did not say any sarcastic words.

The body moved down slightly, and the long knife was clenched in both hands, and the chakra in the body surged out quickly, and the slightest thunder shone brightly, and countless birdsong-like sounds were heard.

His chakra attributes are thunder and fire, but because the thunder escape ninjutsu is relatively scarce, and the family does not include the reason that the B-level or above thunder escape, he still uses the fire escape ninjutsu as the dominant.

After a long period of knife training, he found another direction to use the thunder attribute.

Uchiha Izuna raised his head, his eyes narrowed slightly, his hands clenched the long knife, blue thunder and lightning wrapped around the long knife, and then swung forward violently, and a blue electric light appeared instantly, striking with a huge momentum.

"Swordsmanship, Ninjutsu, Naraku Thundertwin!"

'Boom!! ’

The two powerful attacks collided with each other, and the sound of the wind blade cutting and the roar of thunder and lightning were endless, and the blue-blue light was entwined, and then it suddenly burst out in the next moment as if it was ready to be fired!

The air wave erupted from the center, and the gravel and fallen leaves of the surrounding tens of meters were all swept away, and the howling wind blew across the faces of the two, and the light blue and pitch-black long hair surged, which did not affect the eyes of the two of them.

'Poof! Click......'

The sound of double knives in the sheath sounded.

"Fire Escape: Dragon Fire Technique!"

"Fire Escape: Hao Fireball Technique!"

Uchiha Kura and Uchiha Izuna held the hilt of the sword with one hand, and raised two fingers with the other, and with a deep breath in their mouths, their chests bulged, and then they exhaled violently.

'Boom!! ’

A blazing straight line fire dragon appeared, and then collided with the huge fireball that appeared in front of it, the blazing temperature was self-evident, in this dry season of autumn wind, it was undoubtedly worse, and the air was a little drier again.

'Brush! ’

Uchiha Zang slammed the long knife out of the sheath, and then stepped on the ground, his body rushed into the burning flames, the long knife in his hand surging with a blue wind attribute chakra, and the trajectory of the rotation remained unchanged, driving the surrounding flames to rise a few points.

“…… I've seen through this little trick a long time ago! ”

Uchiha Izuna smiled disdainfully, and then he didn't intend to rush into the sea of fire, holding the hilt of the knife with one hand, and quickly sealing with the other, a complex and lengthy seal, which made him spend more than two seconds, and then straightened his chest and took a deep breath, and spit out violently!

"Fire escape, fire extinguished!!"

'Wow!! ’

A large sea of fire engulfed the already burning area, and then the blazing flames rose again.

Uchiha Izuna gasped slightly, looked at his masterpiece and nodded with satisfaction, hooked the corners of his mouth and smiled proudly: "The act of rushing into the sea of fire is really the stupidest plan you have in this battle, the high temperature that even the upper shinobi can't bear, do you think you can rush out again?" Wait inside for Mr. Beilu to save you! ”

"Swordsmanship, Ninjutsu, Great Turtlemaki!!"

A shout suddenly came from the sea of fire, and then he felt some changes in the air around him, and the smile on the face of Uchiha Izuna stiffened slightly, and then in his somewhat shocked gaze, a huge air flow swept up.

The tornado swirled around the sea of fire, guiding it to rise slowly more than ten zhang high, and the accumulation flames at the bottom were vacant, and there was no longer the slightest threat, and at the same time, the Uchiha Zang who was holding a knife in both hands and maintaining an upward slashing posture was revealed.

“…… How can it be!? ”

Izuna Uchiha's eyes widened as she looked at the pillar of flames that had been swept up by the tornado, a look of disbelief on her face.

The A-level fire escape ninjutsu was extinguished, and it was easily dissolved by it? How could it be so powerful with the addition of the sword technique of the change of the attribute of the Wind Escape Chakra?

"Swordsmanship, Ninja, One Flash!"

Just as Uchiha Izuna looked up at the sky a little distracted, Kurano in the center of the flame did not linger in the slightest, and the long knife quickly entered the sheath, and then reached out again and pulled it out violently.

It was like an ordinary knife drawing technique, but with the addition of the wind attribute chakra change, the speed was even faster, and his body turned into a blue afterimage in an instant, flashing in front of the opponent, and the long knife slashed out!!

……

'Poof! ’

A crisp knife closing sound.

"Izuna, you've lost again!"

The Uchiha sheathed his long knife and turned his head to look at the distracted opponent.

Naturally, he couldn't really make a move, and when he was about to slash the other party, he turned sideways, and the power of the knife in his hand was to instantly cut the big tree a few feet away behind him in two!

“……”

At this time, Uchiha Izuna suddenly came back to his senses, turned his head to look at the big tree that was cut in two behind him, and cold sweat suddenly flowed on his forehead, he actually lost his mind in the battle again, fortunately it was just a fight, if it was on the battlefield, this kind of mistake was enough to kill several times!

"Quanna, this is the first time this is the first time? Every time you're done with a fight, you're going to have that look on your face, and I don't owe you any money. ”

Uchiha Zang plunged his long knife into the ground beside him, raised his head to look at the ugly look on the other party's face, and couldn't help but roll his eyes.
