Summon the Villain: Marvel.

Bai's figure flickered in the ice mirror. He looked at the three members of Team 7 gently, his voice still calm: "You are already seriously injured. Continuing to fight will only increase the pain. Please surrender."

Sasuke's injuries were obviously more serious than the other two. Blood was flowing from his wounds. His face was pale but his eyes were still full of fighting spirit. He tried his best to stand firm and looked at Bai coldly: "We will not surrender."

Sasuke opened the One Magatama Sharingan and struggled for the last moment: "Fire Style: Great Fireball Technique!"

Bai sighed softly, his heart full of contradictions. He didn't want to hurt these young ninjas, but he had to complete the order of Zabuza-sama. He formed a seal again, preparing to launch a new round of attacks.

"Ice Release: Thousand Killings Water Flying!" Countless ice needles flew out from the ice mirror again, pointing directly at Sasuke.

Puff, puff, puff...

"Sasuke!!!"

When Naruto saw Sasuke's injuries, his anger and anxiety exploded instantly. He felt the Nine-Tails chakra begin to surge in his body, and his whole body radiated red chakra light. His eyes turned into animal pupils, beard-like lines appeared on his face, and the nails on his hands and feet became sharper. The Nine-Tails chakra surged in his body, and his temperament became wild and dangerous.

"Naruto?" Haruno Sakura looked at the changes in front of her in surprise. She could feel the powerful force erupting from Naruto's body, but why was her own body so scared?

Naruto growled, his eyes flashing red, and he rushed towards Bai, his speed and strength increased several times than before. Bai did not expect Naruto to change so much, and was suppressed in an instant.

"How is this possible?" Bai was shocked, but he remained calm. He quickly formed seals and tried to use the Ice Escape Technique again.

However, Naruto was too fast, and he shattered the ice mirror behind Bai with one punch, sending ice fragments flying everywhere, forcing Bai to retreat. Naruto continued to attack, and each of his strikes carried the powerful force of the Nine-Tails' chakra. Bai barely defended, but was clearly at a disadvantage.

Naruto was too fast. He shattered the ice mirror behind Bai with one punch, and ice fragments flew everywhere, forcing Bai to retreat. Naruto continued to attack, and each of his strikes carried the powerful force of the Nine-Tails Chakra. Bai barely defended, but was clearly at a disadvantage.

Naruto's eyes were empty, full of wildness and rage, and he kept swinging his fists, each blow carrying a violent force. Bai quickly formed a seal and tried to fight back: "Ice Release: Ice Mirror Technique!" However, the ice mirror was shattered by Naruto's punch as soon as it was formed. The ice mirror fragments flew in the air, and Bai had to keep retreating.

Bai made hand seals again, releasing more ice needles: "Ice Style: Thousand Killings Water Shooting!" Countless ice needles shot towards Naruto, but Naruto waved his fists, and the red barrier formed by the Nine-Tails Chakra easily blocked all the ice needles. The ice needles shattered around Naruto, and he continued to approach Bai without any damage.

Whenever Haku tried to fight back, Naruto's attacks were always fast and fierce, interrupting his spell. Haku's movements became slower and slower, and his defense became more and more exhausted. Each of Naruto's punches was full of devastating force, and Haku's body could barely stand under the huge impact.

Naruto suddenly leaped into the air, clenched his fists, and the red Nine-Tails chakra surged around him, forming a terrifying force. He smashed down on Bai's head. If this blow hit, Bai would almost certainly die.

Just as Naruto's fist was about to fall, a huge hand suddenly appeared in the air and firmly grasped Naruto's wrist. Naruto was stunned for a moment, roared and tried to break free, but the strength of this hand made him unable to move.

"Calm down, kid." Doflamingo's voice was filled with cold sarcasm. His figure appeared between Naruto and Bai, and he grabbed the runaway Naruto in his hand.

Doflamingo looked at Naruto in a rampaging state, with curiosity and contempt in his eyes. He felt the violent chakra in Naruto's body, and the power was impressive, but for Doflamingo, it was not enough to make him feel afraid.

"This brat's power is indeed extraordinary." Doflamingo sneered, "But it's just power."

Naruto roared, the Nine-Tails' chakra surged wildly in his body, his eyes flashed red, full of wildness and anger. Naruto struggled to break free from Doflamingo's restraints, swung his fists, and the energy waves formed by chakra exploded in the air.

Doflamingo smiled lightly, and moved his fingers slightly. Countless thin threads suddenly appeared in the air. These thin threads were like invisible nets, quickly entangling Naruto's limbs. Naruto struggled angrily, but these thin threads were extremely tough and his strength could not shake them.

"The ability of the String-String Fruit is more than just that simple." Doflamingo said coldly, and moved his fingers again. The thin thread suddenly tightened, forcing Naruto's body to lean forward, and his movements became slow.

Naruto roared, and the Nine-Tails' chakra formed a red barrier, trying to shake the thin wire away. But Doflamingo just smiled lightly, twisted his fingers slightly, and the thin wire changed with his movements, tightly wrapped around Naruto's body, fixing him firmly in place.

"It seems you still need to learn how to control your power, kid." Doflamingo sneered, moving lightly and quickly appearing in front of Naruto.

Naruto glared at Doflamingo angrily, the red light in his eyes becoming more and more intense, his strength was constantly accumulating, ready to explode. However, Doflamingo did not give him this opportunity. He flicked his fingers lightly, and the thin wire suddenly tightened, cutting into Naruto's skin, forcing him to roar in pain.

"Don't you understand yet? Strength is not everything." Doflamingo said coldly, and the thin wire in his hand quickly changed, forming a sharp whip, and lashed Naruto's body fiercely.

Naruto tried to use the Nine-Tails Chakra to resist, but the whip's speed and power were far beyond his expectations, and it hit him hard in the chest. Naruto's body was knocked out and hit the ground heavily, spurting blood from his mouth.

Doflamingo showed no mercy and quickly followed up, swinging the whip again, lashing Naruto's limbs fiercely. Each blow was powerful, and Naruto's body was repeatedly knocked away, and blood stained the ground red.

Finally, Doflamingo stood in front of Naruto and stared at him coldly: "This is the lesson you deserve, brat."

Naruto barely raised his head, the red light in his eyes gradually faded, and the Nine-Tails' chakra was also gradually weakening. His body was covered with scars and blood was constantly flowing out, but his eyes remained firm.

"Are you still not willing to give up?" Doflamingo smiled lightly, and moved his fingers again. The thin wire suddenly tightened and cut into Naruto's body, causing him to roar in pain.

Finally, Naruto's body began to lose strength, his eyes slowly closed, and he fell to the ground, losing consciousness.

Doflamingo retracted the string and looked coldly at Naruto who was lying on the ground: "Strength is not everything, kid. You still have a lot to learn."

He turned to look at the shocked Shiro and Haruno Sakura and said calmly, "Your battle is over."

......

Zabuza and Kakashi were fighting fiercely. Suddenly, they both felt a strong aura approaching. They immediately stopped and looked cautiously not far away. A tall and cold figure slowly appeared. It was Nathan Hawke. His expression was indifferent, and there was no emotion in his eyes.

Kakashi immediately became alert, his Sharingan slightly moving, ready to deal with any unexpected situation: "Who are you, sir?"

Nathan Hawke glanced at Kakashi and Zabuza indifferently, and said in a cold tone: "If you can satisfy me, I will tell you."

Seeing Nathan Hawke's bragging, Zabuza was furious and sneered, "Who do you think you are? How dare you be so arrogant?"

Before he finished speaking, Zabuza swung the beheading sword in his hand with a sharp sound of wind towards Nathan Hawke. However, Nathan Hawke simply raised his hand lightly, and the telekinesis burst out instantly. Zabuza's attack was blocked by an invisible force, and his body was bounced back and fell heavily to the ground.

Zabuza angrily got up from the ground, a trace of blood oozing from the corner of his mouth, his eyes full of astonishment and anger: "You...what kind of monster are you?"

Nathan Hawke looked at him indifferently, his voice cold: "If you can't satisfy me, I will kill you with my own hands."

After saying that, Nathan Hawke's body burst out with an amazing momentum, and a strong pressure instantly enveloped the entire battlefield. The air seemed to be compressed, and Kakashi and Zabuza felt this momentum and were shocked. Zabuza clenched his teeth, cold sweat broke out on his forehead, and Kakashi's expression became unusually solemn.

Kakashi made a quick decision and said to Zabuza: "Put aside our grudges and fight him together, otherwise we will all die."

Zabuza glared at Kakashi. Although he was extremely unhappy, he knew that now was not the time to fight. He gritted his teeth and agreed: "Okay, let's join forces first."

Kakashi and Zabuza looked at each other and quickly stood together, ready to join forces to fight this powerful enemy. Nathan Hawke stared at them coldly, his hands gently clenched into fists, and powerful energy surged around him. His momentum was like an insurmountable mountain, oppressing Kakashi and Zabuza.

Kakashi and Zabuza stood together and exchanged a firm look. Nathan Hawke's momentum made them realize that this was not an ordinary battle, and they had to go all out to have a chance of survival.

Kakashi whispered, "Zabuza, his strength and speed far exceed ours. We must work closely together and take advantage of our respective strengths."

Zabuza nodded and responded in a low voice: "I will use water jutsu to contain him, and at the same time look for an opportunity to attack with the beheading sword. Your Sharingan can see through his movements and counterattack."

Kakashi thought for a moment and added: "We need to create enough interference, use the mist of water jutsu to cover, and then attack alternately. His reaction speed is extremely fast, we can't leave him any chance."

Zabuza tightly grasped the beheading sword, with a fierce flash in his eyes: "I will do my best to make sure he doesn't have a chance to breathe."

Kakashi nodded, his eyes full of determination, "I will use Lightning Release to assist in the attack and try to break his defenses as much as possible. Our goal is to weaken his physical strength so that he can't use his full strength."

Zabuza showed a sly smile: "Well, since we have decided to join forces, let's not leave any room for retreat and go all out."

Kakashi and Zabuza quickly decided on a strategy. They adjusted their breathing and each took a soldier pill, preparing for this life-and-death battle.
