Summon the Villain: Marvel.

Across the Worlds: Naruto.

Location: Wave Country.

Duration of stay: one month.

Number of people carried: Nathan Hawke, Doflamingo, Borsalino.

This world can be anchored: Anchored.

"Boss, is this where we're going to stay for a month?" Borsalino asked in his usual lazy tone.

Nathan Hawke nodded and looked around sharply: "Yes, this is the world of Naruto. We have a month."

Doflamingo gave a sly smile: "So, what is our mission?"

"Just follow my instructions." Nathan Hawke said calmly.

As they were discussing, they heard a fierce fight in the distance. Nathan Hawke signaled the two men to be quiet, and the three of them quickly hid their bodies and moved towards the direction where the sound came from.

Not far away by the river, they saw a "fierce" battle. The members of Team 7 - Naruto, Sasuke, Sakura and their teacher Kakashi - were fighting a ninja holding a huge beheading sword. This ninja was Zabuza Momochi, and next to him was a young man who looked frail but agile - Bai.

Zabuza held a huge beheading sword, his eyes flashing with a fierce light. Every time he swung the sword, it was with amazing power and speed, and the air was filled with the sharp sound of the blade breaking through the air. Kakashi stood calmly opposite him, his Sharingan moving slightly, capturing every subtle movement.

Zabuza growled and rushed towards Kakashi, the blade pointed directly at his head. Kakashi dodged lightly and drew out a kunai to fight back. The kunai and the sword collided, making a harsh metal collision sound. The two quickly distanced themselves, and Zabuza's eyes revealed a hint of appreciation: "Your reaction speed is good, little dog."

Kakashi looked back calmly: "Your swordsmanship is not bad, but your movements are too straightforward."

Zabuza sneered: "Then try this!"

He quickly formed a seal: "Water Style: Water Dragon Bullet Jutsu!" A huge water dragon leaped out of the river and pounced on Kakashi with its fangs and claws bared. Kakashi immediately formed a seal and quickly completed the same technique: "Water Style: Water Dragon Bullet Jutsu!" Another water dragon rushed forward, and the two water dragons collided violently in the air, splashing water everywhere.

With the help of the mist produced by the collision of the water dragons, Zabuza quickly hid in the thick fog and disappeared. Kakashi looked around vigilantly, his Sharingan flashing slightly, trying to penetrate the thick fog to find the opponent's trace.

Zabuza's voice came from the fog, with a hint of sarcasm: "Mist Hidden Technique, this is my territory. You can't see anything clearly here."

Kakashi sneered: "Do you think this little fog can trap me?"

He quickly formed a seal: "Wind Style: Great Breakthrough!" A strong gust of wind whistled out from Kakashi's hands, blowing away the surrounding fog and revealing Zabuza's figure. Zabuza did not expect Kakashi to use such a large-scale wind style, and a hint of surprise flashed across his face, but he quickly adjusted himself, gripped the beheading sword tightly, and rushed towards Kakashi again.

"Do you have enough kakara?"

"That's enough for you."

Kakashi calmly faced the enemy, and the two clashed again. Zabuza's swordsmanship was fierce and direct, and each strike carried a killing momentum. Kakashi dodged flexibly, using the insight of the Sharingan to accurately predict Zabuza's every move. Their battle lasted dozens of rounds in just a few seconds, and every collision sparked strong sparks.

"Your Sharingan is indeed powerful, but my sword will not lose to anyone!" Zabuza roared suddenly, and the blade, with a sharp gust of wind, chopped straight at Kakashi's head.

Kakashi leaned slightly to the side, and the blade grazed his cheek, leaving a tiny trace of blood. His eyes remained calm, and he quickly stabbed Zabuza's waist with his kunai. Zabuza blocked the attack with his sword, took advantage of the momentum to retreat, and distanced himself.

The two of them looked at each other breathlessly, and there was a hint of fear in Zabuza's eyes: "Copy Ninja Kakashi, you are indeed not an ordinary ninja."

Kakashi smiled slightly, his eyes gleaming with determination: "I will protect my students and won't let you hurt them."

Zabuza's expression darkened: "Then let's see who has the last laugh!"

On the other side of the battlefield, Bai sighed softly, put his hands together, and formed a complex seal. The air around him suddenly became cold: "Ice Escape: Ice Mirror Technique!"

Countless crystal clear ice mirrors rose from the ground and quickly formed an ice mirror array around Naruto, Sasuke and Haruno Sakura. Bai's figure appeared in each ice mirror and said gently: "Please stop, I don't want to hurt you."

Naruto was full of confidence, with a hint of disdain on his face: "Don't think you can scare us with this kind of ice!"

Sasuke sneered, his eyes flashing with fighting spirit: "Humph, you don't know how strong I am."

Haruno Sakura nervously clenched the kunai in her hand, with determination in her eyes: "We won't give up easily!"

Bai's voice was still gentle, but it revealed a hint of helplessness: "Since you have decided to continue fighting, I will not show mercy."

Naruto took the lead in launching the attack. He quickly formed seals with his hands: "Multiple Shadow Clone Technique!" In an instant, multiple clones of Naruto appeared on the battlefield. They rushed towards Bai at the same time, trying to break through the ice mirror formation.

Sasuke followed closely behind, forming hand seals and making a quick move: "Fire Style: Great Fireball Jutsu!" A huge fireball flew straight towards Bai, trying to melt the ice mirror with flames.

Haruno Sakura stood behind and quickly pulled out a few shurikens from her ninja tool bag and threw them at Bai, trying to distract him.

Bai's ice mirror technique is very powerful. His figure quickly moved in each ice mirror, easily avoiding Naruto's clone and Sasuke's fireball attack. The fireball hit the ice mirror, and although a lot of steam was generated, the ice mirror remained as solid as before.

"I'm sorry," Bai whispered, and quickly formed seals with his hands, "Ice Release: Thousand Killings Water Shooting!" Countless ice needles shot out from the ice mirror, pointing directly at Naruto, Sasuke and Haruno Sakura.

Naruto's clone quickly blocked the front, but the ice needles penetrated the clone and disappeared into the air. Sasuke dodged swiftly. Although he avoided most of the ice needles, a few still grazed his body, leaving minor wounds. The remaining few ice needles flew towards Haruno Sakura, who blocked a few ice needles with a kunai at the last moment, but her movements were obviously slower than Naruto and Sasuke, and a nervous look appeared on her face.

Bai's figure kept flashing in the ice mirror. He continued to gently warn: "You are quite powerful, but in this ice mirror formation, I have an absolute advantage. Please stop and don't cause any more harm."

Naruto gritted his teeth, his eyes burning with an unyielding fighting spirit: "We won't give up, Sasuke, Sakura, are you ready?"

Sasuke sneered, clenched the kunai in his hand and looked at Bai: "Stop making noise, you loser."

Although Haruno Sakura was nervous, her eyes showed determination: "I will do my best to support you!"

Bai's eyes showed a trace of sadness: "In this case, let me see your determination."

Bai's figure moved quickly in the ice mirror, his eyes full of sadness and determination. He sighed softly, and then quickly formed a seal: "Ice Release: Magic Mirror Ice Crystal!"

More ice mirrors emerged from the ground, completely trapping the three members of Team 7. Bai's figure flickered in each ice mirror, as if he was everywhere. Naruto, Sasuke, and Haruno Sakura were separated, but they could still see each other's situation through the ice mirrors.

Naruto gritted his teeth and quickly formed seals with his hands: "Multiple Shadow Clone Technique!" A large number of shadow clones appeared instantly, but Bai was too fast. He moved in each ice mirror and quickly appeared in front of each shadow clone, using ice needles to accurately break them. Every time a shadow clone disappeared, Naruto felt a pain.

"Multiple Shadow Clone Technique!" Naruto increased the number of shadow clones again, but the result was the same. Bai's ice needles continued to penetrate the shadow clones, and finally hit the real Naruto. Naruto fell to the ground, his arms and legs were stabbed by ice needles. Although there was not much bleeding, the pain still made his face pale.

"Naruto!" Haruno Sakura exclaimed, but she was also surrounded by Bai's ice mirror and could not get close.

Sasuke saw Naruto was injured, and he was furious. He formed seals with his hands: "Fire Style: Great Fireball Technique!" A huge fireball rushed towards the ice mirror, but Bai dodged it lightly, and the ice mirror remained as solid as before. Sasuke sneered, quickly approached the ice mirror, and tried to attack with a kunai, but Bai appeared in front of him again.

"Too slow." Bai whispered, and the ice needle in his hand flew out again, pointing directly at Sasuke. Although Sasuke dodged quickly, he was still stabbed by the ice needle, leaving several horrible skin wounds and bleeding.

"Sasuke!" Sakura Haruno exclaimed again, her eyes full of worry, but she was trapped in the ice mirror array and could not be rescued.

Bai looked at Haruno Sakura, with a hint of tenderness in his eyes: "You don't have to get involved in this battle." His gestures softened slightly, and he did not launch a fatal attack on Haruno Sakura. Despite this, Haruno Sakura still felt a huge pressure, she tightly grasped the kunai, trying her best to stay calm.

"I......"

Naruto, Sasuke and Haruno Sakura were trapped in the ice mirror array, and they were all injured to varying degrees. Naruto covered his wound and gritted his teeth to persist; although Sasuke was bleeding, his eyes were still burning with fighting spirit; although Haruno Sakura was not fatally injured, her heart was filled with anxiety and powerlessness.

Bai stood in the center of the ice mirror formation, looking at the three members of Team 7, and sighed softly: "I am moved by your determination, but I cannot allow you to disrupt Lord Zabuza's plan. Please forgive me."

The battle situation on the other side made Zabuza and Kakashi feel the tense atmosphere. Zabuza glanced in the direction of Bai, a sneer appeared at the corner of his mouth, and then turned to look at Kakashi.

"It seems that your students are not very good, Kakashi." Zabuza said sarcastically, the beheading sword in his hand flashing with cold light.

Kakashi frowned slightly, his Sharingan flashing in his eyes: "Zabuza, your assistant is not simple either. However, you should take care of yourself first."

Zabuza sneered and rushed towards Kakashi quickly, holding the beheading sword high up and slashing down with a strong gust of wind. Kakashi quickly dodged sideways and swung the kunai in his hand backhand, pointing directly at Zabuza's waist.

Zabuza turned around swiftly and blocked the kunai's attack with his broadsword. The blade collided with the kunai, making a harsh metallic sound. The two men quickly distanced themselves, their eyes full of fighting intent.

Zabuza stopped talking nonsense and quickly formed seals with his hands: "Water Style: Great Waterfall Technique!" A huge stream of water gushed out from behind Zabuza and rushed straight towards Kakashi with unstoppable force.

Kakashi calmly formed a seal and quickly performed a ninjutsu: "Earth Style: Earth Flow Wall!" A solid earth wall rose from the ground, blocking Zabuza's water flow. The water flow hit the earth wall, splashing water everywhere, but the earth wall remained stable.

Zabuza snorted coldly and rushed towards Kakashi quickly, slashing down with the beheading sword in his hand with a sharp gust of wind. Kakashi took advantage of the earth wall to quickly move aside and stabbed Zabuza's side with the kunai in his hand.

Zabuza blocked with his broadsword, and the two men clashed again, with blades and kunai colliding continuously and sparks flying.

Zabuza's strength and speed are both amazing, but Kakashi uses the insight of his Sharingan and his agile body movements to constantly dissolve Zabuza's attacks.

The two men quickly distanced themselves from each other, both breathing heavily, but the fighting spirit in their eyes became even stronger.

Zabuza looked at Kakashi with disdain: "Your defense is indeed good, but how long can you last?"

Kakashi responded calmly: "As long as I protect my students, time is not a problem."

Zabuza formed hand seals again: "Water Style: Water Dragon Bullet Jutsu!" A huge water dragon leaped out of the water and rushed towards Kakashi.

Kakashi quickly formed hand seals and performed the same technique: "Water Style: Water Dragon Bullet Technique!" Another water dragon came towards him, and the two water dragons collided violently in the air, splashing water everywhere.

Zabuza used the water dragon's cover to approach Kakashi again, and the beheading sword in his hand slashed down with a fierce murderous aura. Kakashi quickly retreated and used kunai to block.

With a bang, Kakashi quickly retreated, trying hard to hold back the blood flowing from the corner of his mouth, and quickly formed a seal: "Lightning Release: Raikiri!"

A strong lightning burst out from Kakashi's hand and went straight to Zabuza. Zabuza's eyes flashed with surprise, but he quickly adjusted and used the big sword to block the lightning attack. Although he suffered a lot of impact, he still stood firm.
