Naruto: We are invincible

He couldn't help but chuckle as he watched a patrol of ninjas pass beneath him without even noticing his presence.

At this moment, he noticed light coming from a room at the end of the corridor.

Naruto used Kamui to pass through the wall and came to the infirmary. He stayed inside the wall and noticed that there were several guards in the room.

Unless the doctor was imprisoned here and forced to treat the enemy, there shouldn't be so many guards here.

Coupled with the heavy atmosphere and the pervasive smell of fear in the room, Naruto became more certain of his judgment.

He created a shadow clone and went behind the other guard. He couldn't kill two people at the same time without alerting the other guard.

boom!

All the doctors in the infirmary turned around and saw the two guards lying on the ground.

They were shocked to see a blond man with blue eyes and Sharingan standing in the middle of the room. The doctors backed away, expecting they would be killed as well.

"I can get you out of here." Naruto said as he looked at them. There were about ten doctors in the room, all wearing standard white coats.

"We are about to attack this fortress. If you stay here, you may get hurt by mistake." Naruto explained. At this time, a female doctor stood up.

"Thank you for saving us." She said. She had an ordinary face, black hair and black eyes. "My name is Nao." She said.

Naruto nodded and created a shadow clone, asking the doctors to gather together. A flash of yellow light appeared and they disappeared. Naruto created several more shadow clones, turning into doctors and guards, so that no one would notice anything unusual when they came in.

## Mei Terumi's Side ##

A yellow light suddenly appeared next to Mei Terumi, startling her. She turned around and saw that it was Naruto who had returned with ten doctors.

"They are the doctors imprisoned here. I'll be there soon..." Naruto said before he turned into smoke and disappeared.

"Take them to the medical station," Mei Terumi ordered. The doctors were taken to the medical tent.

No one noticed the sneer that flashed across Nao's face, or the black marks that appeared in her red eyes.

## Fortress Interior ##

After leaving the infirmary, Naruto continued along the long corridor until he finally reached the exit leading to the outside area. He looked forward and saw the city gate not far away.

He was thinking about how to open this heavy-looking city gate.

The gate is equipped with a counterweight and requires at least three people to push it open.

Mei Terumi was right, this door was indeed reinforced with chakra, and Naruto could see faint chakra flowing through the wood.

He had to find a way to open the city gate quietly so that the rebels could attack more easily.

"There's nothing we can do." Naruto said, teleporting to the gate. He placed his hand on the gate, and a huge rune array spread out from his hand, gradually covering the entire gate.

This is a standard detonator, only it's been magnified...

Naruto teleported to a safe area and prepared to detonate. He formed a single hand seal and the gate began to flicker with light.

boom!

With a loud bang, the city gate was blown to pieces. All the ninjas in the fortress were awakened by the explosion. A few seconds later, a piercing alarm sounded through the night sky. Mei Terumi heard the sound and immediately ordered her troops to attack.

"Charge!" Mei Terumi shouted, and she and all the soldiers broke through the fog and launched a fierce attack on the castle.

In less than five seconds, the fortress was surrounded by thousands of fully armed ninjas. Deafening explosions and metal collisions echoed throughout the fortress.

"Mei Terumi!" Naruto jumped down from the wall and joined Mei Terumi. "You take a few hundred people to the back of the castle and sneak in through the back door." He said.

"There is no back door." said Mei Terumi.

"I opened one." Naruto said seriously. Terumi Mei was stunned for a moment. "It's just a small hole, you can plug it up later." Naruto explained. Terumi Mei sighed.

"Teams A to D, follow me!" Mei Terumi ordered. She led some of the men around to the back of the castle and launched an attack from the rear, attacking the enemy from both sides.

"Okay, okay." Naruto turned around when he heard the voice and saw a Mist Ninja walking towards him, who seemed unaffected by the chaotic battlefield.

"We finally meet...Senju Naruto." said the man.

"Who are you?" Naruto looked at the enemy in front of him. He was wearing a standard Mist Village ninja uniform with a bulletproof vest on the outside.

"We're not familiar enough to call each other by our first names. My name is Toshio, a new member of the Seven Ninja Swordsmen of the Hidden Mist." Toshio said as he pulled out a large sword from his back.

"I see," Naruto said, pouring chakra into the seal on his wrist and summoning his chakra dagger.

"I've always felt that the Senju clan was overrated. After all, the 'strongest' clan was wiped out in the First and Second Shinobi World Wars, while the 'weakest' clan survived." Toshio taunted, but his provocation did not work, as Naruto remained expressionless.

"Show me what you can do, Senju Naruto, the Thunder God of Konoha, the son of Yellow Flash, and the grandson of Uchiha Madara." Toshio shouted, raising his sword and rushing towards Naruto.

Naruto quickly used his Sharingan to analyze the enemy's strength and found that he was just a Jonin with a relatively large amount of chakra.

"It seems that the title of 'Seven Ninja Swordsmen' has made him a little too proud of himself." Naruto thought.

Toshio swung his sword, trying to chop Naruto in half, but only hit Naruto's afterimage.

When the sword hit the ground, he realized that he had missed. He turned around and blocked Naruto's sweeping attack with the blade.

"Chidori-ryu!" Naruto said, and lightning flashed on the short sword in his hand and his hand. Since both swords were made of metal, the current was transmitted to Junfu, causing him to twitch all over. He jumped up and stepped back, with smoke coming out of his hands.

Junfu put the sword behind his back and began to make hand seals. Naruto was very familiar with this ninjutsu.

"Water Style: Mist Hiding Technique!" As soon as he finished speaking, he was surrounded by thick fog.

"Game over, kid," Toshio said, disappearing into the mist.

Naruto shook his head and stood there motionless. It was pitch dark, why would he move? He soon realized that Junfu was a complete novice in assassination. He could even hear Junfu's breathing.

Naruto was tired of this farce and decided to end it quickly.

"Go to hell!" Toshio yelled, appearing behind Naruto, raising his sword, trying to chop him in half.

He had hit, or thought he had. The blade went through Naruto's body and came out the other side.

"What are you?" Toshio screamed in horror. Naruto turned around and looked him in the eye.
