Konoha Village, Hokage's office, Tsunade sits leisurely on a chair and sipps tea.

After taking office as Hokage, Tsunade realized how busy the Hokage's work was.

Every day, there are endless documents, from task entrustments from all over the country to instructions and material purchase orders from ordinary Konoha villagers.

Leisurely leaning back in a chair and enjoying a moment of silence like today is also a pleasure that Tsunade does not often enjoy.

Turning his head to look at the sky obscured by clouds, Tsunade remembered the seventh class that had left a few hours earlier.

From Konoha Village to the Loulan Ruins, it should be there now.

Hope all the best.

Just then, a knock on the door broke the silence of the office.

walked in with a large stack of papers in his hands, barely higher than the top of Shige's head.

"Tsunade-sama, the archives are almost full of papers, and I need your instructions to dispose of some unimportant documents."

With a bang, the tall pile of papers was placed on Tsunade's desk, which had just cleared out some blank space.

"Mute... You're deliberately trying to get me a job, right? ”

"How so, these are also the Hokage's work."

Tsunade gave a very terrifying look, and Shizune hurriedly waved his hand to explain.

Despite the reluctance of 10,000 in his heart, Mute still picked up the files on the pile of documents and looked at them.

"This is..."

"These are all old documents from twenty years ago, and they record the tasks that Konoha Village has carried out before."

“...”

Tsunade did not respond, but silently opened the document in his hand.

The assignment of this document is blank, indicating that this is an internal task from Konoha Village.

But on the performer of the mission, Tsunade saw several familiar names.

Bo Feng Shuimen, Autumn Road Dingza, Oil Girl Zhiwei.

(Due to the recommendation of the wave wind and water gate, Kakashi Hachiki was specially added as the fourth person of the mission)

Difficulty: S level

The mission of the four generations of Hokage...

Just seeing the name made Tsunade interested in continuing to read.

...

In this mission document, it is not stated what the mission goal is, but the mission location is a sight to behold.

Mission location: Loulan Kingdom.

Tsunade knew that twenty years ago, the ancient kingdom of Loulan or the ruins of Loulan was still called the country of Loulan, because the country of Loulan was a country that still existed at that time.

Tsunade's eyes lit up, and he never expected that the location of the task document that he took out and was about to be sent to be processed would be the same as today's mission location.

And creation makes people, the mission twenty years ago was carried out by Bo Feng Shuimen, and this mission is Naruto Uzumaki.

As the sixth Hokage, Tsunade naturally knows the relationship between these two people.

At the end of the document, there is a rather long summary of the task.

According to the rules of Konoha Village, as long as it is an A-level or above task, it is necessary to record the task summary written by the task executor.

This is to prevent the task client from arguing over whether the task has been completed in the future, and it is to be kept as evidence later.

Although the entrusting party of this task is someone from inside Konoha Village, there is no prevarication, but I still wrote a task summary as usual.

The person who wrote the summary of this task was none other than Bo Feng Shuimen.

...

On the first day of infiltrating Loulan Kingdom, this country is very strange, there are no pedestrians on the streets, but there are a lot of guards, especially the closer to the central tower, the more heavily guarded.

Infiltrate Loulan Kingdom on the second day and exclude 70% of the buildings.

On the third day of infiltrating Loulan Kingdom, only the central tower has not yet been investigated.

On the fourth day of infiltrating the Loulan Kingdom, he discovered that the puppet soldier was made by An Lushan, the minister of the Loulan Kingdom, and fought with him, and discovered an unknown creature in the dragon vein.

The creature is called the Flying Hydroid, a semi-material creature that resembles a hydra.

The body is malleable, highly resistant to physical attacks, can float in the sky, and has the ability to become temporarily invisible.

The attack method is Tempest, and its power is about the same as that of S-level Wind Escape Ninjutsu.

The creature killed An Lushan, the minister of Loulan, and caused the destruction of Loulan.

With the skill of the Flying Thunder God, he personally conducted a second investigation of the Loulan Kingdom, and found that the Flying Hydra was afraid of light, and if it was not for the invasion of its territory, it would be hidden in the dragon vein cave deep underground most of the time.

Therefore, it is recommended that Loulan be set as a prohibited area to avoid disturbing the flying polyps here.

Above.

...

Shizune stood quietly holding the guinea pork, but in fact her eyes kept looking at Tsunade's expression.

Tsunade's expression went from calm at first to thoughtful, to surprised, and even panicked.

It's hard to imagine how such a document from twenty years ago that was about to be disposed of because of its age could make Tsunade's expression change so much.

Suddenly, Tsunade slapped the document in his hand on the table and shouted, "Quick! Find a way to get in touch with Class 7! ”

Shizune was so frightened by Tsunade's sudden movements that she almost dropped the guinea in her arms to the ground, "Tsunade-sama, what's going on?" ”

Tsunade didn't hide it, and said directly: "This document was written by the four generations of Hokage twenty years ago, and the four generations of Hokage determined that there was a very dangerous creature in the Loulan Kingdom, called the Flying Hydra. ”

"It's definitely not easy to make a creature that the fourth Hokage thinks is dangerous, and the seventh class must be withdrawn immediately!"

"Yes!"

Although Shizune didn't know exactly what kind of existence the Flying Hydra was, judging from Tsunade's expression and reaction, the situation must be very urgent.

Shizune immediately ran out of the Hokage's office with the guinea in his arms, and Tsunade picked up the document in his hand and read it.

Since the fourth generation of Hokage suggested that it be listed as a forbidden area, why didn't the third generation of Hokage implement it?

If you think about it, the reason is simple.

The country of Loulan has fallen, it has become a ruin, normal people will not be idle to wander there, go to the empty area next to it at least some black market transactions.

There is also the fact that the desert where the Loulan Country is located is neither the land of the Fire Country nor the Land of the Wind Country, and Konoha Village has no right to govern it.

But in the end, not enough attention has been paid to it.

Twenty years ago, the existence of this strange creature was thought to be just a special existence, just like some special psychic beasts in the ninja world, and they didn't know what they symbolized behind it.

But Tsunade, who is familiar with the changes in recent years, knows that the existence of these strange creatures is not one.

The Ancients, Shogues, Mi Go, Rainbow of the Stars, Shagai, Ghouls, Flying Hydras...

Countless unspeakable creatures appeared, as if to show only one thing.

They are coming back...

......

The black and white bird, which has always been painted in ink, hovers in mid-air, and on it are Sakai and Sakura from the seventh class.

"Naruto!"

The purple pillar of light had just devoured Naruto and Yamato, and even though they were no longer visible, Sakura still didn't give up shouting.

It wasn't until the pillar of purple light on the altar in the center of the dragon vein gradually dimmed that Sakura saw Naruto and Yamato lying on the ground.
