After taking over the snake uncle's foundation, Sasuke came to surrender on his own initiative.

Hinata's support was long overdue.

This made Kakashi realize that something unexpected must have happened somewhere.

"Were we stopped by someone..." In a corner under the barrier, Kakashi's expression darkened slightly.

Then, he looked inside the barrier with worry.

A huge white ice pick can be vaguely seen on the ground in the center.

The surrounding flames and mud flows intertwined and merged with each other, like a giant red and brown dragon galloping, which made it impossible for him to see the figures of the two warring parties clearly.

"The Saruman was frozen, and his physical skills changed from restraining to being restrained again... Moreover, the Third-sama couldn't keep up with his speed at all... He could only use large-scale ninjutsu to suppress him indiscriminately." Kakashi's face changed slightly, and he was worried. "Now he has to rely on his rich combat experience to react and judge... Has he been forced to this point?"

Kakashi knew very well that this suppression was short-lived. Once Sarutobi Hiruzen's chakra ran out, or he was slightly careless, with the terrifying speed of the Sound Village leader, as long as he got close to him, the outcome could be decided in an instant!

Moreover, he was confident that he was not mistaken about this combination ninjutsu. It was one of Sarutobi Hiruzen's most powerful combination ninjutsu: Earth Dragon Flame Flow!

This type of compound ninjutsu consumes a great deal of chakra.

It might not be a big deal for the young Sarutobi Hiruzen, but Kakashi knew it best that with the Third Hokage's current physical condition, using this level of technique would be an extremely heavy burden on his chakra and mind.

"The Third-Hero... he is old after all! After evacuating the people, Asuma and the others all went in the direction of the summoned beast, resulting in no jonin supporting the Third-Hero... that three-headed giant snake summoned beast can be restrained by no more than ten jonin. Is there some kind of invasion in the village that I don't know about?"

Thoughts raced through Kakashi's mind, and his expression soon became uncertain.

He was not sure whether Sarutobi Hiruzen inside the barrier would be able to hold on if he continued to wait.

After hesitating for a long time, he winked at Kai beside him inconspicuously, then glanced at the figure of the black-clad ninja carrying a big sword.

Speaking of sealing techniques, he learned from Minato Namikaze and his master's wife is Kushina, so he actually knows a thing or two.

Although the sealing technique and the barrier technique have different functions and external forms, their principles are actually the same.

Now that things have come to this, he can only give it a try.

"Hmm!" Kai's face trembled, and then he understood instantly. His already restless heart was boiling instantly! He turned his head and looked at Zabuza excitedly, and shouted passionately, "I understand! Kakashi-san! He is the enemy that even you can't deal with, right!?"

A look of confusion immediately appeared on his face, and he turned to look at Kakashi, "By the way, what did you say this guy's name was?"

Kakashi's eyes went dark, and he put his hand on his forehead. "Didn't I tell you twice? You forgot again?" He moved his mouth and was about to remind him, but he saw Kai shaking his head and muttering to himself, "Forget it!"

Then, Kai's mouth twisted, and his teeth suddenly gleamed. He gave Kakashi a thumbs up and said confidently, "In that case! It's time for the proud blue beast of Konoha to make an appearance!"

Kakashi:......

Zai Buzha’s brows tightened, (???) how could he die?

After saying that, Kai suddenly gathered his fists together and clenched them on both sides of his waist. A ferocious look appeared on his face and he shouted angrily.

"Eight Gates of Ninjutsu! Injury Gate! Open!"

boom--

Veins suddenly popped up on Kai's forehead, and his skin began to become swollen and red at a speed visible to the naked eye. His black bowl-cut hair all stood up straight and swayed in the wind in the sudden violent invisible aura.

In the blink of an eye, streams of green light rose from its body and into the air.

"This guy... opened the fourth gate right away?" Kakashi on the side was slightly surprised, with a flash of worry in his eyes.

Although Kai has been able to skip the door in front and directly open more "doors" through years of practice, this sudden violent behavior will undoubtedly cause greater damage to the body.

Kakashi immediately understood that before the fight even started, Kai had already gotten too excited...

whoosh-

A green figure came as fast as the wind, and Zabuza felt that in the blink of an eye, there was a person in front of him.

A black foot surrounded by a green halo rapidly enlarged in the sight.

Excitement - Konoha's Diamond Force Cyclone!

"The same physical skills as Kakashi, so old-fashioned!" Zabuza snorted coldly and swung the beheading sword on his shoulder vertically.

Wuwuwu——

The blade cut through the sky, causing a sharp howling of the wind.

But it was obvious that this was just a casual move on his part.

Zabuza unsurprisingly underestimated his enemy because he thought Kai, who was wearing a green tights and behaving strangely, looked like a clown.

With a clang, the moment the tip of his foot landed on the back of the beheading sword, a metallic sound was heard. Then it broke apart, and although Zabuza reacted and dodged sideways, the kick still landed on his left shoulder without any surprise.

"puff!"

His pupils suddenly widened, and a stream of blood mist spurted out of Zabuza's mouth. His left shoulder collapsed, and he and his sword flipped over and flew backwards.

"pat-"

Kai landed on the ground with both feet, turned around and blinked at the stunned Kakashi, then grinned, "Hey, Kakashi-san, were you impressed by my kick just now?"

"......" The black mask on Kakashi's face twitched slightly, and he was a little speechless, "Don't underestimate the enemy, Kai!"

Beep——!

Kai snapped his fingers and chuckled, "Yeah, got it!"

More than ten meters away, Zabuza quickly stood up from the ground and looked at Kai again, his expression becoming extremely gloomy. "This guy..."

Whether it was the lingering taste of blood in his mouth or the sharp pain in his left shoulder, they both made him realize that this Konoha ninja, whose dress and behavior were strange, was actually a greater threat than Kakashi!

Zabuza wiped the blood from the corner of his mouth with his hand, and when he looked at Kai, a ferocious look appeared on his face, and he said in a cold voice, "You thick-browed guy, you succeeded in irritating me!"

His sinister eyes were fixed on the green figure, and in an instant, the pupil technique residing in his left eye was activated!

Zabuza shouted softly, "Bang!"

With Kai as the center, the cubic space with a diameter of 2x2 suddenly collapsed!

When a crisp sound like glass shattering was heard, all matter in the area, including Kai, turned into nothingness in an instant and dissipated into the vast alien space.

And in the calm space, a pitch-black cube suddenly appeared and was shrinking at an extremely slow speed, as if the space was healing automatically.

It's like a whole watermelon, but someone has scooped out a piece of the center with a spoon.

It is pure black, with a hint of desolate atmosphere.

Mangekyō Sharingan, space pupil technique - collapse!
