Ankel Bandian Sky Fortress, as the headquarters of the Kingdom of Sky in the past, gained great fame during World War II.

But because of this, in the battle with Konoha, this huge aerial fortress also became a key target of attack.

Although it was not shot down in the end, it was seriously damaged and had to make an emergency landing in the Land of Fire. After being covered up by the remnants of Kong Ninja, it became a relic in the mouths of nearby villagers.

Decades have passed, and the original Konoha has long forgotten this short-lived enemy in World War II.

But the Kong Ninjas have not forgotten the enemy who destroyed their country.

Over the years, the remaining Kong Ninjas have been lurking in the dark under the leadership of Shennong, growing in strength bit by bit.

Flying ninja tools, kunai guns, aircraft carriers and other weapons of the Kingdom of Sky were all built one by one.

Only the Ankel Bandian Air Fortress was not repaired by the air ninjas because they were afraid that the people of Konoha would notice it.

When Kakashi led a group of Konoha ninjas into the deep underground fortress according to Yushu's instructions, it could be seen that many of the surrounding walls were covered with moss and vines.

Inside, one can see deep cracks one after another.

After crossing a huge boulder that fell from the ceiling, Kakashi unfolded the internal structure diagram written by Yu Shu, led everyone straight into the core, and headed towards the control hall.

Tread! Tread! Tread!

Suddenly, there was a sound of footsteps in the shadows ahead.

Kakashi waved his hand, and everyone scattered and quickly hid.

When a four-person Sora Ninja patrol team arrived, several black shadows were seen running out quickly, and the former fell down limply before he had time to react.

It was inevitable that the air ninja would jump over the wall and destroy the air fortress control console and even release Zero-Tail. Kakashi and his team did not choose to attack head-on with great fanfare from the beginning.

In the following time, after the Konoha ninjas assassinated several air ninja patrols without any danger, they finally arrived outside the control hall.

There are a large number of empty ninjas stationed inside, so it is unrealistic not to cause a disturbance.

At this time, Kakashi pulled up the Konoha forehead protector, revealing the three Magatama Sharingan, and said coldly: "Attack with all your strength!"

Instantly!

A large number of kunai and shurikens were thrown towards the control hall.

Many empty ninjas who had no time to react fell to the ground in pain.

"Who?"

The leader of an empty ninja escaped the attack of the ninja tool in time, and when he was questioning angrily, he suddenly saw a green figure rushing in front of him very fast, and shouted passionately:

"Konoha's powerful whirlwind!"

The Kong Ninja leader only felt his eyes blur, and then his whole body suddenly hit the wall beside him with the sound of muscles and bones breaking in his body.

Boom!

A fierce fight broke out.

After the empty ninjas were caught off guard, they finally reacted and took out their kunai guns, which were like hair dryers, and sprayed a large amount of kunai at the Konoha ninjas who were killing them.

"Wind Escape·Fengchen Technique!"

As soon as he increased his speed, Sarutobi Asuma, who came to the front of the crowd, quickly formed seals with his hands, and a fierce whirlwind came from his mouth, blowing away all the large numbers of kunai that came towards him.

On the side, Yamashiro Aoba, who was performing the art of scattering thousands of crows, raised his finger.

In an instant, hundreds of crows were seen flying towards Kong Ninja, disrupting his sight.

Taking advantage of this opportunity, the Konoha ninjas who did not want to use too many area-of-effect ninjutsu, lest they destroy the place, got close and started fighting with the empty ninjas.

"Rakuzakuna no Jutsu!"

Falling cherry blossoms suddenly appeared in the sight of several air ninjas who were fighting Yuhi Kurenai, and everyone fell into a deep sleep in an instant.

After easily taking care of these people, Kurenai Yuhi was about to find her next target when a sharp sound suddenly broke through the air behind her.

She focused her eyes, turned her kunai in her hand, and was about to turn around when she saw a familiar figure quickly come over.

Bang! Bang!

After a few clicks, when Kurenai Yuhi looked, she saw Sarutobi Asuma holding the unconscious Sora ninja in one hand and Feiyan in the other, making a handsome pose, and said to her in a cool tone: "Kuren,

Be careful!"

Hong couldn't help but rolled his eyes when he heard this, and said angrily: "I'm not fine at all!"

After saying that, she didn't bother to pay attention to Asuma, who still had the same moral character as when she was a child, and went to kill the other empty ninjas.

When Asuma saw this, he rubbed his nose and continued to follow as usual.

The strength of the air ninja is mostly reflected in the absolute advantage in aerial combat. In terms of personal quality alone, it is far inferior to the Konoha ninja.

Therefore, when the two sides were fighting in close quarters, the entire battle soon became one-sided.

Soon, after all the empty ninjas in the control hall were eliminated, Kakashi, who saw that the plan was mostly successful, was about to say something when he suddenly heard a rush of footsteps not far away.

Apparently the air ninjas in other places heard the fighting and came to support.

Kakashi's face remained unchanged and he ordered: "The first team stayed in the control hall to protect everything here. The others went to various parts of the fortress to clean up the remaining empty ninjas in the fortress."

"Yes!"

After receiving the order, the Konoha ninjas dispersed one after another.

Kakashi also ran towards the passage where the noise just came from.

Soon, the sharp screams of thousands of birds were heard in the dark passage.

What followed was a series of screams from the empty ninja before his death.

An hour later.

The remaining air ninjas in the air fortress were cleared by the Konoha ninjas.

When Kakashi returned to the control hall, based on the information he had tortured from Shennong, he reached out and pressed on a wall, and instantly saw a floor next to him move away, revealing a secret downward passage.

Through this passage, you can go to the core power room of the Sky Fortress, which is where Zero Tail is sealed.

After telling others to wait where they were, Kakashi jumped and entered the secret passage.

A minute later, I walked to the edge of the passage and saw the huge cylindrical space outside with seal characters engraved on the walls. In the middle of it, Shennong had not yet been put into Yushu's body, but was sealed by yellow.

When he saw a huge strange thing called Zero Tail wrapped in membrane, like a snake, with a "zero" mask on its head, even though Kakashi was prepared for it, he still couldn't help but feel shocked.

Kakashi knew that the strange thing below was not something he could solve by himself. At this time, he took out the Flying Thunder God Kunai in his arms, and then looked at his pocket watch.

When he found out that there were still twenty minutes left before the scheduled time, he calmly waited.

The Flying Thunder God Kunai is used as a coordinate, although its owner can consume chakra to teleport here.

But this does not mean that the latter can sense everything around the coordinates before teleportation.

This is also the reason why Minato didn't show up in time when Obito and Lin were in danger.

Although Zero-Tail is not a real tailed beast, and even has the title of shame of tailed beasts, it is not something that normal ninjas can deal with.

Therefore, after estimating the time required for the operation before departure, Yunting, who is busy with official duties, will arrive at the right time.

Originally, Kakashi was worried that he would not be able to complete the task within the specified time limit.

Fortunately, Yushu's unexpected appearance made the operation go smoothly, and it was completed twenty minutes earlier than the planned time limit.

The first mission after leaving ANBU was finally completed successfully.

This made Kakashi breath a sigh of relief, but at the same time, the shadow that still lingered in his heart that the last time he served as captain caused all the team members, including Lin, to die in battle also gradually dissipated at this moment.

"Obito...Lin..."

"I will take your blessings and continue walking with a smile."

Kakashi touched his left eye and sighed.

......

Twenty minutes later, the Flying Thunder God was nowhere to be seen, and Yunting appeared on time.

"It seems Kakashi you have completed your mission very well." Yunting looked around and knew that he was at the Zero-Tail Seal, patted Kakashi on the shoulder and praised him.

"Although the number of Kong Ninjas is large, their combat power is much weaker than originally thought. In addition, this operation also relied on the help of a child." Kakashi, who did not take any credit, reported seriously.

"Oh? Children? It seems that your journey has been unexpectedly exciting." Yunting smiled slightly and said, "Let's talk to me in detail later. As for now, let's deal with the zero tail in front of us first."
p>

After saying that, Yunting lowered his head and looked down at Lingwei, who was wrapped in a yellow sealing film.

The reason why Zero-Tail was named by the Sora Ninja who discovered it was because, like the tailed beast, it was a creature composed of dark chakra.

Naming it Zero-Tail also expresses the Kong Ninja's desire to have a tailed beast weapon as powerful as the five major nations.

Unfortunately, compared to the real tailed beasts, Zero-Tail's power comes from the dark side of human hearts, and as long as humans cannot completely get rid of the darkness, it will not die.

But in terms of actual combat effectiveness, it is just average.

In the original work, it was weakened due to inhaling excessive amounts of chakra from Naruto and Sasuke, and the reason for its defeat is really speechless.

It’s no wonder that the air ninjas back then mostly used it as a power source for their aerial fortress.

For today's Yunting, naturally he doesn't care about the so-called dark chakra.

Similar to the Kong Ninja back then, he also planned to use the Zero-Tail as a perpetual motion machine.

After all, this guy will never die, so naturally he can be squeezed as much as he wants.

Glancing down at Zero Tails who was restless due to the arrival of a strange smell, Yunting ordered Kakashi on the side: "You stay here."

After saying that, he took a step forward and immediately learned the Earth Escape and Light and Heavy Rock Technique before performing it.

I saw his body slowly falling down with great lightness.

Although due to the reason why the ninjutsu was performed in the middle, chakra continued to seep out of the body and was absorbed by Zero Tails, who was currently the power source of the air fortress, but with the huge amount of chakra and extremely fast recovery speed, Yunting could not handle this.

Don't care.

"Don't push yourself to pieces! Zero-tail."
Chapter completed!
