Although Orochimaru was quite disgusted by Rope Tree's huge amount of money to rebuild the fortress, he finally agreed to take charge of the construction project himself.

With Orochimaru's IQ, it was easy to link this project to the war against the Land of Wind, and although he didn't know the specific plan, he could be sure that the Air Fortress must be crucial in this war.

Coupled with the fact that Rope Tree was his partner, and had recently provided him with the Spiritualization Technique to help him solve the problem of immortal reincarnation, he decided to spare a little time to meet Rope Tree's request.

Orochimaru also has a very high research talent in mechanical weapons, and he also has the help of the scientific research team of the Sky Country, so this reconstruction will not take him much time, he only needs to grasp the general direction, and someone will naturally complete the details.

So on the same day, Orochimaru summoned the scientific research team and began to design the drawings according to the requirements of the rope tree, and the reconstruction work was soon in full swing.

A large number of material resources were continuously transported underground, and a professional engineering team was left in the empty country, but there was still not enough manpower, and in order to speed up the progress of the transformation, the rope tree ordered to recruit civilians to help with the construction.

Since the air base has been occupied by Konoha, both the civilians of the Land of the Sky and the refugees from the Land of Rain are very grateful for the benevolence of the rope tree, and in the absence of explicitness, ordinary civilians will only think that they are building underground facilities, and will not think of the tall weapons of the Air Fortress, so they are worried that the secrets of the fortress will be leaked out.

With the help of a large number of laborers, and the abundant materials brought by the Rope Tree himself using the Sacred Tree space, the construction of the fortress went very smoothly, and the renovation was finally completed in time for the arrival of autumn.

The farmers at the airbase were very happy, not only did they find a lucrative job during their slack time, but they were also able to return home in time to prepare for the autumn harvest.

And Rope Tree is also very happy, the transformation of the fortress is completed in time, and he can launch a war offensive according to the plan.

At the beginning of September, the summer heat has not yet dissipated, and the trees are still chirping lively, and the coolness of autumn has not yet come.

On this day, something unusual happened in the Konoha Air Base, the Imperial City, which was located in the center of the base, and the neighborhoods within three hundred meters of the surrounding area were locked down and placed under martial law.

In fact, the items in the imperial city had been emptied long before they were used, and all the servants of the Konoha ninja army who were originally stationed in the imperial city had been evacuated.

The civilians living near the Imperial City had all moved after receiving a generous demolition fee, and not only did they have no complaints, but they were happy because they had made a windfall.

Therefore, today's martial law has aroused the curiosity of many civilians, and they have speculated that this incident must be inseparable from the previous construction project under the imperial city.

In the underground fortress, the rope tree and the prawn pill led a group of sincere empty ninja to gather together.

"Your Excellency, everything is ready! Please also order. "The Minister of the Air Force of the Former Country, who is currently the deputy commander of the Konoha Air Base, asked for his life with an excited face.

Not only him, but the ninjas of the former Sky Country present all had similar expressions. Although the Empty Fortress no longer exists, there is still a strong affection for this empty fortress.

This was once the dream of the entire Sky Nation higher-ups, and now this dream is finally coming true, and although there is a new leader, they are still excited.

The rope tree looks very calm on the surface, but in fact, it is very excited inside, and the air fortress is a man's romance!

However, he did not lose his mind, but said calmly: "Confirm that the civilians have been safely evacuated?" I don't want any surprises! ”

Seeing that Rope Tree was still caring about the civilians at this time, the ninjas present couldn't help but have respect in their hearts, compared to the original royal family of the Sky Country, this is a qualified monarch, worthy of the name of Skywalker.

"Lord Qiqi, the area of three hundred meters around the imperial city has been completely blocked, and after many searches, it has been confirmed that there are no civilians." The Minister of the Air Force replied with a respectful face.

"Excellent! Then start taking to the skies! ”

With the order of the rope tree, the ninjas who had been ready in the fortress began to control themselves.

In the energy chamber under the hall, the runes like electronic originals were activated again, and a large number of chakras poured out of the body of the Zerotail clone, smoothly injected into the surrounding walls under the control of the rope tree, and then injected into the various machines in the fortress through complex transmission pipes.

"Buzz!" After obtaining sufficient energy, the entire fortress was like a giant beast awakened from its slumber, and all its parts began to run at high speed.

Bursts of reports rang out in the hall.

"Energy transportation is normal!"

"The powertrain is working!"

"Weapon system recharged!"

"The defensive barrier is open normally!"

"The fortress begins to take off!"

As the fortress began to activate, on the ground, the curious onlookers standing on the periphery of the blockade area suddenly felt a slight tremor on the ground, and then a loud rumbling sound came from the ground.

The sudden change caused the civilians to let out a burst of exclamations, but since there were ninjas on the scene to maintain order, there was no chaos, and everyone looked at the imperial city in the distance with wide eyes.

......The earth cracked, and slowly protruded upward, as if a giant beast was about to break through the ground, and the original tall and majestic imperial city shook violently like an unsteady old man, and the thick city wall began to crack like the ground in the violent shaking.

After a loud "boom", the imperial city, which had stood for hundreds of years, finally collapsed, stirring up a puff of smoke and dust on the ground.

The last vestiges of the royal family of the empty country have finally disappeared completely, leaving the onlookers in amazement.

Soon, an even more shocking change completely dispelled the emotions in everyone's hearts.

In the midst of the collapsed ruins, a huge building slowly rose and broke through the ground.

When the building was completely raised above the ground, everyone finally saw him in its entirety.

This is a giant fortress that is taller than the Imperial City, and the shell of the fortress is completely integrated, shining with silver-white light, and it is actually made of metal throughout!

The surface of the fortress is covered with dense turrets, and the thick barrels stand up in the air, like hedgehogs, which makes people's scalps tingle at the first sight.

The fortress was surrounded by a layer of purple transparent enchantment, which was the most basic defensive enchantment four purple flame arrays, adding a touch of gorgeous and mysterious color to the fortress.

The appearance of this intimidating fortress shook everyone's hearts, and everyone couldn't help but cheer as it continued to rise and stand tall in the sky.

The collapsed imperial city was soon forgotten by the populace, and the newborn fortress became a spiritual symbol for all.
