Summon the Villain: Marvel.

"Thank you, Kakashi!" Might Guy raised his thumb and responded loudly, his eyes flashing with fighting spirit. He suddenly punched out, knocking the other clone away and hitting the ground heavily.

The two stood back to back, cooperating with each other tacitly. Kakashi's Sharingan kept scanning the surroundings, capturing every potential threat, while Might Guy used his strength and speed to quickly deal with every approaching enemy.

"Ada!" Might Guy shouted again, and smashed his fist into a steel armor like a sledgehammer. The chest armor of the steel armor was dented, and the internal electronic system was instantly paralyzed, and fell to the ground.

"Kai, we need to hold on until support arrives." Kakashi said calmly, with a firm look in his eyes. Although they all had many scars on their bodies, their will was still indestructible.

"No problem, Kakashi! We can definitely hold on to the end!" Might Guy responded with a big laugh, his eyes burning with fighting spirit and passion.

Just then, a new wave of enemies came. Clones and Iron Armors rushed towards them like a tide, and the battle became more intense.

"Ada, da da da!" Might Guy shouted, and quickly rushed forward, punching the enemy like raindrops. Each of his punches was powerful, and the enemy was defeated step by step.

Kakashi quickly formed a seal on the side, "Water Style: Water Dragon Bullet Technique!" A huge water dragon surged out from his hand and suddenly pounced on the enemy. The power of the water dragon knocked the clones and the steel armor all over the place, and many enemies were knocked to the ground in an instant.

Might Guy and Kakashi stood back to back on a messy battlefield, their bodies covered with scars from the battle, but their wills remained unbreakable. The number of enemies seemed endless, and they had just repelled a new wave of enemies, and while they were catching their breath, they suddenly saw the enemies begin to retreat, as if they were intentionally leaving a passage.

"What's going on? Do you know, Kakashi?" Might Guy frowned, his eyes full of vigilance.

"I don't know either." Kakashi was also confused. He looked around, ready to respond to new changes at any time.

At this moment, two figures slowly walked in from the passage that the enemy had made way for. The leader was Zabuza, who stared coldly at Kakashi with murderous intent in his eyes. Next to him was a man in a black uniform with a lazy look, and that was Borsalino.

"Zabuza?" Kakashi recognized Zabuza instantly and was shocked. "Why are you here?"

Zabuza sneered, "Kakashi, long time no see. I still remember that we once fought side by side, but today, I am here to take your life."

Might Guy frowned and looked at Kakashi: "Kakashi, this ninja who looks like the Mist Shadow, do you know him?"

Kakashi nodded, his eyes showing a hint of solemnity: "Yes, he is a rebel ninja from the Hidden Mist Village. We have worked together once before."

At this moment, Borsalino yawned lazily, stretched, and said lazily: "What a troublesome guy. Zabuza, leave this mushroom-headed guy to me. You go deal with that guy called Kakashi."

Zabuza nodded and looked at Kakashi coldly: "That's exactly what I want."

A hint of fighting spirit flashed in Might Guy's eyes, and he got into a fighting stance: "Mushroom Head? Are you talking about me? Haha, I haven't met such an interesting opponent in a long time."

Borsalino gave a lazy smile: "Yes, it's you. Let's start." As soon as he finished speaking, his body suddenly turned into a golden light, and instantly appeared in front of Might Guy, kicking out with a strong light.

"Ada!" Might Guy reacted quickly and blocked the attack with his arms crossed. Although he blocked the attack, the huge force still made him take a few steps back, and a deep groove was kicked out on the ground under his feet.

"Yellow... flash!" Kakashi's pupils dilated.

"Kakashi, what are you looking at!" Zabuza unhappily drew out his beheading sword and looked at Kakashi coldly: "Kakashi, this time, I will not show mercy."

Kakashi drew out his kunai, his eyes showing a hint of coldness: "Zabuza, I will not show mercy."

The two men's eyes met in mid-air, filled with murderous intent. Zabuza suddenly rushed towards Kakashi, and with the sound of the beheading sword breaking through the air, he fiercely slashed at Kakashi. Kakashi quickly retreated, and at the same time, he formed a seal, "Water Style: Water Dragon Bullet Jutsu!" A water dragon gushed out from Kakashi's hand and suddenly pounced on Zabuza.

“I am extraordinary now!”

Zabuza sneered, swiftly slashed the water dragon with his sword, and continued to approach Kakashi. The two quickly engaged in a fierce close combat, with swords flashing and shadows intertwined, making waves of metal collision sounds.

"It's split!" Kakashi was still shocked. What on earth was the power coming from the other party?

On the other side, the fight between Might Guy and Borsalino also became extremely fierce. Might Guy's fists blasted out like cannonballs, each of which carried great power, while Borsalino dodged at an extremely fast speed, his body constantly turning into golden light and teleporting on the battlefield, causing most of Might Guy's attacks to miss.

"Ada!" Might Guy shouted and kicked Borsalino suddenly. Borsalino turned into golden light again and instantly appeared on the side of Might Guy and punched him. Might Guy quickly dodged sideways, but was still hit and felt a sharp pain.

"What a troublesome opponent." Might Guy gritted his teeth and said, but the fighting spirit in his eyes was even more intense. This battle would be a difficult duel, but he would never give up easily.

Kakashi and Zabuza were in a fierce confrontation, with swords flashing and sparks flying.

“Clang! clang! clang!

Kakashi's kunai and Zabuza's beheading sword collided frequently, and each blow carried tremendous power and momentum.

"You have become stronger, Zabuza." Kakashi panted, his eyes full of vigilance and surprise. He could clearly feel that Zabuza's power was more terrifying than before.

Zabuza sneered, his eyes flashing with fanaticism: "Kakashi, I have been reborn and gained new strength." As he spoke, he suddenly shook, and the muscles on his body expanded rapidly, and a sense of power came over him. Zabuza tore off the bandages wrapped around his body, revealing his strong muscles.

"Look, this is my new power." Zabuza raised the beheading sword and swung it towards Kakashi.

"Bang!" Kakashi blocked the fatal blow with a kunai, but he felt a pain in his arm and the kunai broke. He quickly stepped back and drew out another kunai, but Zabuza didn't give him a chance to breathe. He approached suddenly and smashed down with a beheading sword with a strong wind.

"Bang!" Kakashi used kunai to block again, but this time the kunai was directly blown away. The beheading sword slammed into the ground with great force, stirring up a cloud of dust.

Kakashi quickly retreated, his eyes full of solemnity. His Sharingan could capture every move of Zabuza, but the opponent's strength was too strong, and every blow was destructive.

"Clang!" Zabuza swung the beheading sword again, and Kakashi quickly dodged it, but the blade grazed his shoulder, leaving a deep wound. Blood gushed out quickly, and Kakashi felt a sharp pain, but he remained calm and quickly adjusted his posture.

"Do you think you can escape?" Zabuza sneered, his eyes flashing with fanaticism and confidence. He approached quickly, and the beheading sword swung again, the blade cutting through the air with a sharp sound.

"Swoosh!" Kakashi quickly stepped back and formed seals with his hands, "Earth Style: Earth Flow Wall!" A thick earth wall quickly rose from the ground and blocked Zabuza's attack.

"Bang!" Zabuza's beheading sword smashed hard against the earth wall, and the huge force smashed the earth wall into pieces, but Kakashi had already taken the opportunity to distance himself. He gasped and quickly formed seals with both hands again, "Raikiri!" Strong lightning burst out from his hands, accompanied by a sharp sound of electricity.

Zabuza sneered and looked at Kakashi with disdain: "With just this little power, do you think you can defeat me?" As he said that, he suddenly jumped up, raised the beheading sword high, and smashed it towards Kakashi with destructive force.

"Sizzle, sizzle!" The Raikiri and the beheading sword collided violently, and the electric current and the blade intertwined fiercely in the air, making bursts of harsh sounds. Kakashi felt a huge pressure, and his hands were almost shaken off, but he still gritted his teeth and persisted.

"You are too confident, Zabuza." Kakashi whispered, with a gleam of determination in his eyes. He quickly mobilized his chakra, and the Raikiri in his hand became more intense, and the electric current burst out like lightning, forcing Zabuza back a step.

A hint of surprise flashed in Zabuza's eyes, but then he became more fanatical: "Very good, very good! This is interesting!" As he said that, he suddenly approached again, and swung the beheading sword again, slashing towards Kakashi with incredible power.

"Clang!" Kakashi used his kunai to block again, but this time it was shattered directly, and his body was blown away by the huge force and hit the ground heavily. Kakashi struggled to stand up, his chest heaving violently, but his eyes remained firm.

"Hmph, is this your limit, Kakashi?" Zabuza sneered and stepped closer, with his beheading sword raised high, ready to give Kakashi the final blow.

Kakashi gritted his teeth, his body was covered with scars, and his breathing became rapid. He knew that he was almost powerless to resist, Zabuza's power was too strong. Just when Zabuza's sword was about to chop down, suddenly, a voice came from the sky.

"Earth Escape: Yellow Spring Swamp!" A deep and powerful voice was heard, and the ground suddenly became soft. Zabuza's feet suddenly sank into the quagmire, and his beheading sword came to a halt.

"What!" Zabuza looked around in surprise, only to see a tall figure falling from the air and standing steadily beside Kakashi.

"Jiraiya...sir..." Kakashi looked at the man in front of him, a hint of surprise and gratitude flashing in his eyes.

Jiraiya sneered and looked at Zabuza sharply: "It seems that you are having a lot of fun, Zabuza." As he said that, he quickly formed seals with his hands, "Fire Style: Great Fireball Jutsu!" A huge fireball spewed out of his mouth and went straight towards Zabuza.

Zabuza tried to pull his feet out of the mud, but the fireball was approaching, so he had to retreat quickly to avoid the fatal blow. The restraint of the mud and the power of the fireball temporarily made him lose the opportunity to attack Kakashi.

"Kakashi, we have to retreat!" Jiraiya quickly came to Kakashi, grabbed him and pulled him up from the ground.

"But..." Kakashi looked at Zabuza, still feeling a little unwilling.

"No buts. Now is not the time to be stubborn." Jiraiya said in a low voice, his voice full of firmness and determination.

Zabuza looked at Jiraiya and Kakashi angrily, with a hint of unwillingness in his eyes: "You can't escape, next time, I will definitely kill you!"

Jiraiya sneered and quickly formed seals with his hands, "Wind Style: Fierce Wind Palm!" A strong wind blade shot out from his hands and went straight towards Zabuza.

"Hmph!" Zabuza snorted coldly and killed it with one sword, but he also missed the opportunity.

"Let's go!" Jiraiya shouted in a low voice, and helped Kakashi quickly leave the battlefield.
