Reborn Naruto: Starting with its own system

Jiraiya was already very happy, he knew Naruto's strength. In his opinion, this duel was a done deal. However, Tsunade didn't know that! She was still immersed in the anger after being provoked by the brat Naruto, and she didn't realize the great potential of Naruto. Jiraiya looked at Tsunade and Naruto with interest, his heart full of expectations. He seemed to have seen Tsunade's surprised expression after seeing Naruto's true strength.

Soon, under the leadership of Jiraiya, a group of four arrived at a barren mountain outside the village.

Tsunade on the side said angrily: "It's just a one-on-one fight with this brat, why go to such a remote place?"

She frowned, looking at the desolate scene around her, and her irritability became stronger. Naruto stood quietly by the side, with a calm expression, and seemed not to care about this place. However, on the way here, Naruto had secretly eaten a fruit of power. He wanted to defeat Tsunade with the attack method that Tsunade was best at.

Tsunade looked at Naruto's calm appearance, and her anger in her heart became even worse. She felt that this brat was too arrogant to be so calm in front of her. However, she didn't know what Naruto was thinking. Naruto secretly felt the powerful force brought by the fruit of power surging in his body. He clenched his fists tightly, as if he had seen the dawn of victory.

At this time, Jiraiya stood aside with a mysterious smile on his face. He knew Naruto's strength and expected this duel to shock Tsunade. Shizune looked at the two nervously, her heart full of worry. She knew Tsunade was powerful, but seeing Naruto's calmness, she had no idea who would win this battle.

The wind on the barren mountain blew gently, blowing up the dust on the ground. Tsunade shook her hair impatiently, glared at Naruto and said, "Kid, are you ready to learn a lesson?" Naruto raised his chin slightly and responded with a firm look in his eyes, "Come on, let me see how strong the legendary Sannin is." For a moment, the atmosphere on the barren mountain was extremely tense.

Then Tsunade raised her right hand, extended a finger and slashed it hard on the ground. With a loud "boom", the ground trembled instantly, and a huge crack spread rapidly towards Naruto's feet like a ferocious python. The soil and rocks at the edge of the crack collapsed one after another, raising clouds of dust. Tsunade's attack showed her powerful strength and precise control, as if announcing to Naruto that her strength should not be underestimated. Naruto's eyes condensed, and he quickly jumped up to avoid the rapidly approaching crack. He adjusted his body in the air, secretly marveling at the power of Tsunade's attack. Jiraiya and Shizune on the side were staring at the two people in the field, wondering how Naruto would deal with Tsunade's next attack. Tuntun was so scared that he huddled into a ball, hiding in Shizune's arms and trembling.

Seeing Tsunade already attacking, Naruto no longer hesitated. "Shave!" He instantly flashed to Tsunade's side, his speed was so fast that it was astonishing. Then, without hesitation, he threw a punch and went straight to Tsunade.

Looking at Naruto who suddenly appeared in front of her, Tsunade was shocked. "Is this the Flying Thunder God Technique?"

But the rapidly approaching fist did not allow him to think much, and he could only hastily raise his hands to resist.

With a loud "bang", the powerful force directly knocked Tsunade dozens of meters away.

Shizune and Jiraiya stared at the scene in a daze. They really couldn't imagine that Naruto had such power.

Tsunade's body drew an arc in the air, half squatting and landing heavily on the ground, raising a cloud of dust. She slowly stood up, her eyes full of shock and confusion. She never thought that Naruto's power was so strong that he could knock her so far.

Shizune opened her mouth wide, her face full of disbelief. She had followed Tsunade for many years and knew her strength, but the scene before her was unbelievable. Jiraiya was also stunned. Although he knew that Naruto was very strong, he didn't expect that he could actually compete with Tsunade in terms of strength.

Naruto stood there, looking at Tsunade firmly. He knew that this was just the beginning, and Tsunade would not be defeated so easily. He was ready to face Tsunade's more fierce attack.

Tsunade's eyes shone, and the contempt in her heart completely disappeared. She moved her numb arms and re-examined Naruto in front of her.

"Kid, I didn't expect you to have such power." Tsunade said in a deep voice.

Naruto raised his chin slightly, "This is just the beginning."

Tsunade snorted coldly, stepped on the ground, and she rushed towards Naruto like an arrow. Naruto was not afraid and rushed forward again.

The two men's fists collided again, making a deafening roar. The powerful force wave spread in all directions, and the surrounding soil and rocks were lifted up, forming small pits.

This time, Tsunade was not knocked away again, but she also felt that Naruto's strength was increasing. She gritted her teeth and used all her strength to fight against Naruto.

Naruto also felt the tremendous pressure, but he did not back down. The power fruit in his body continued to play a role, providing him with a constant supply of power.

The two were deadlocked, neither willing to give in. Jiraiya and Shizune watched nervously, their hearts in their throats. How would this showdown of power end?

As time went by, Tsunade and Naruto's physical strength was gradually depleted. But their eyes remained firm, waiting for the other party to reveal a flaw first.

Finally, Tsunade moved slightly, and Naruto immediately seized the opportunity and increased his strength. Tsunade was shocked by the sudden force and took a few steps back.

Naruto took advantage of the victory and threw another punch. Tsunade quickly dodged sideways, but was still hit by the punch, leaving a shallow scar on her cheek.

"Kid, you really impress me." Tsunade wiped the blood off her face, a hint of admiration in her eyes.

Naruto said nothing, but just stared at Tsunade, preparing for her next attack.

Tsunade took a deep breath, her eyes becoming sharper. She knew she couldn't underestimate this brat anymore. She stretched her shoulders and got into a fighting stance again.

"Kid, you do have some skills, but this is far from enough." Tsunade said domineeringly.

Naruto was undaunted and responded, "Then I'll show you my true power."

After saying that, Naruto's strength surged. He pushed his feet hard, the ground collapsed instantly, and he rushed towards Tsunade like a cannonball.

Seeing this, Tsunade also released all her strength.
