Hell Valley is located in a remote area between the Land of Rain and the Land of Grass.

The location is very remote, if you are not the person who knows the path, it is difficult to find this place.

Just like the Three Great Holy Land, this place full of mystery.

The reason why Nagato found this place was just a coincidence.

It can only be said that the Hellhound race is in very bad luck, so this unlucky thing happened.

Nagato's purpose was only to get a Hellhound summoned beast. As for the destruction of Hell Valley, it was completely an accident.

After all, Nagato has no grudges with these summoned beasts, so he does not need to let them feel the so-called pain.

Hellhounds have lived in Hell Valley for more than a thousand years, and only a few people have come here.

In the Shinobi World War, there was no participation of the Hellhound race. It can be said that they never care about the outside world.

Outside the Hell Valley, there is a barrier for guarding the Hellhound race.

It was because of Nagato discovering this barrier at the beginning that he was able to discover Hell Valley.

Nagato, who owns the Animal Path, will naturally not give up this kind of powerful summoned beast, so Hellhounds are suffering now because of this.

Kakashi moves with his fastest speed, and after two days, he arrived at Hell Valley.

At this time, the Hell Valley barrier has already been broken, and the entrance was already in ruins.

"Kakashi, here is the Hell Valley."

Nanairo said as he jumped down from Kakashi's head, he then looked at the ruined entrance in front of his eyes.

There is anger, sadness, and helplessness.

The home that he has been living for many years had been destroyed. For Nanairo, this emotion is really hard to explain.

This is the case in the Shinobi World. Different groups will fight each other, and then all those killing will bring hatred.

And hatred is never been something that is easy to resolve.

Today you kill someone for revenge of your friends, and tomorrow someone else will kill you to avenge him.

Shinobi's World is like this, wandering back and forth between killing and being killed.

It is too difficult to be united and reach a mutual understanding.

Where there is interest, there will be disputes. This is something that will happen no matter where you are.

In the original work, if it were not for the Five Great Shinobi Villages to have a common enemy, they definitely would not reach the peace that came later.

But even so, how long can this kind of peace last?

After the death of the older generation, can these Five Great Shinobi Villages still maintain this peace?

No one knows, but human nature has never withstood the test.

Kakashi looked at the scene in front of him, and couldn't help being surprised by Pain's destructive power. 'This level of attack, did Deva pain use large scale Shinra Tensei?'

There were gravel wreckages everywhere. It is a shocking sight for Kakashi.

"Nanairo, are we still going in??"

"Of course we still go in."

Nanairo said as he ran inside from the entrance. Seeing this Kakashi followed Nanairo and went in too.

According to the words of the nine little hellhounds before, all the hellhounds were killed in that disaster, except for Nanairo and them. Except for Nanaretsu's body which was taken away by Rikudo Pain, the rest of the hellhounds' bodies were buried by the nine little hellhounds.

Perhaps the reason why the nine little hellhounds were able to live is because Rikudo Pain weren't able to find them, or maybe Rikudo Pain found out about them but didn't care.

Perhaps in Nagato's eyes, they are just weaklings, and there is no need to kill them.

Nagato's heart was kind, but after Yahiko died, his eyes are now blinded with hatred.

Not long after getting inside, they saw graves one after another.

There are more than a hundred graves, both large and small, which is the result of the nine little hellhounds spending several days to make.

Looking at the more than a hundred new graves, the tears in Nanairo's eyes gradually fell.

Because at this time, the Hellhound race was almost annihilated!!

It can be imagined how much hatred in Nanairo's heart right now.

"All of you, I swear by the name of Nanairo that one day, I will take revenge for you, and I will also bring Nanaretsu's body back to Hell Valley. This is my, Nanairo's lifetime oath!"

Kakashi silently looks at Nanairo without saying anything.

When he first entered Hell Valley, Kakashi had already increases his perception to the maximum and found no danger.

He knows that Nagato currently should be busy reconstructing Amegakure, and he should not have time to come to this place at all.

Or perhaps in Nagato's eyes, there is no more value of this place, so naturally he didn't care anymore.

Nagato, who now claims to be a god, may have become indifferent and ruthless, and regards the common people like ants.

In the face of such a powerful enemy, Kakashi needs to be wary.

"Kakashi, come with me."

At this time, Nanairo suddenly said.

Kakashi was stunned for a moment, and then followed behind Nanairo. After walking for a while, Kakashi then saw a stone gate in a remote corner.

"This is..."

Kakashi was a little puzzled. This stone gate was unremarkable. It looked like an ordinary stone gate, but Kakashi felt that there seemed to be a powerful strength behind this stone gate.

"This is the place that had been guarded by the Hellhound race for generations. Only after our race agrees that someone can enter it."

"What is inside?"

"There is the Gate of Hell!"

"The Gate of Hell? What is that? Is it a Gate to Hell?" Kakashi asked with a weird look.

"Of course not. I am not very clear about what is in it because I have never entered this place either. I just heard my father once said when I was a child that a powerful Shinobi was recognized by our race decades ago and was able to get in."

"What happened later?"

"Later… I don't know."

Kakashi then frowns after hearing Nanairo's answer.

"Then what did you bring me here for?"

"Although I don't know what's inside, my father said there is a mysterious power inside."

"Mysterious Power?"

"Yeah, but Hellhound race won't be able to get in, so I hope you can go in. If you can get this mysterious power, maybe you can defeat that person!"

Kakashi looked at the stone gate and found it plain and unremarkable. 'Does the so-called mysterious power really exist?'

Kakashi thought as it is hard to believe.

"Kakashi, you can rest assured that there will be no danger inside."

Seeing Kakashi was silent, Nanairo thought that Kakashi was afraid, so he quickly said.

If he relies on himself, Nanairo knows that he won't be able to take revenge in his entire life.

After all, his enemy is too powerful.

And the abilities of summoned beasts become stronger with age.

Right now, Nanairo has almost reached the peak of his strength, and there is no way for him to increase it.

But Kakashi is different, he is still young, and humans are creatures that cannot be measured by common sense.

Although Nanairo does not know what is inside this stone gate. He knows that there should be only advantages and no disadvantages inside.

"Okay, Nanairo, I'll go in."

After a moment of contemplation, Kakashi decided to go in.

Although he doesn't know what is inside, for this thing to be guarded by the Hellhound race for generations. Kakashi knows that this thing is worthwhile.
