Hearing Kakashi's agreement, Nanairo were overjoyed and said: "Kakashi, although there should be no danger inside, you must still be careful."

"Yeah, I know, how can I get in?"

Nanairo did not answer, but walked to the side of the stone gate and inserted his claws into a groove.

At this moment, the stone gate emitted a burst of red light, and then it slowly opened.

The deep hole seemed to trying to eat someone.

A gust of wind blew from the hole, and Kakashi couldn't help but shivered.

"Kakashi, be careful." Nanairo said solemnly.

Kakashi is his hope of revenge, and Nanairo absolutely does not want anything to happen to Kakashi.

And once a summoned beast has signed a contract with someone, they will become absolutely loyal.

Of course, Manda from the Ryūchi Cave is an exception.

Kakashi nodded and did not speak. Then he dispels the cold feeling by moving his chakra inside his body.

Kakashi stepped in, but Nanairo stayed outside.

The pitch black darkness make Kakashi unable to see anything at all, so he took out an oil lamp from his ninja bag and continues moving.

The corridor is very long. Even after ten minutes walking, Kakashi still did not see the end.

The cave is very dry. It should be because it is closed all year round, which makes Kakashi feels very gloomy here.

Under the lights from the lamps, Kakashi could see that the surrounding walls were very old. It is obvious that this cave has a very long history.

The cave is very quiet, so quiet that Kakashi can hear his own footsteps.

After another ten minutes, Kakashi finally felt that the place became brighter and the place became much wider.

At the end of the corridor, there is a gate shape thing that is very big!

Kakashi quickened his pace, and soon arrives at this gate shape thing.

"This is..."

Kakashi looked at the thing in front of him, and was surprised!

The thing in front of Kakashi is five huge gates!

Each gate has a different color, but the patterns on each gate are the same!

Rashomon?

Five-Layer Rashomon!

Shodaime Hokage best defensive Ninjutsu, and later it was learned by Orochimaru too.

But why does this thing appear here?

Rashomon is something symbolizing death, and it is also called the gate to hell in the legend.

Kakashi walked to the first Rashomon gate, which was several tens of meters high.

Reaching out and touching the Rashomon gate, he only feels it is cold, and it feels kind of weird.

"Why is Rashomon here? Shouldn't it be the summoned object of Shodaime Hokage, Hashirama Senju? Could it be that the person who Nanairo said that was recognized by the Hellhound race decades ago and entered this place is the Shodaime Hokage?"

Kakashi walked aside and saw that there was a stone platform that can hold something at the side the Rashomon, but now it is empty.

Kakashi felt as if he had discovered something.

If he didn't guess wrong, the one who entered here decades ago must be Shodaime Hokage. Otherwise, how would Shodaime Hokage use Five-Layer Rashomon?

Obviously, this is the place where Shodaime Hokage got the Five-Layer Rashomon.

Originally, there must be contract scroll of Five-Layer Rashomon on top of this stone platform, but it has disappeared right now, and it should have been taken away by Shodaime Hokage.

Right now, Orochimaru is able to use Rashomon, even Orochimaru's subordinates will be able to use it. So it seems that the contract scroll of Rashomon should be taken away by Orochimaru when he defected.

Kakashi was a little surprised. He didn't expect that the so-called forbidden area in Hell Valley was actually the place where Rashomon was placed.

If there is Rashomon's contract scroll here, it is indeed a good thing.

But right now, there is no Rashomon's contract scroll. So Kakashi feels that it is a shame.

The Rashomon gates were really big, so Kakashi couldn't move it at all.

Kakashi was a little disappointed, as it seems that there is nothing he can get inside here.

Look at the huge Rashomon gates, Kakashi couldn't help but smile wryly.

It seems that he didn't get anything at all inside here and makes all his cautiousness lost its meaning.

But since he's already here, Kakashi didn't mind to do something to the Rashomon gates.

Kakashi opened his Sharingan, and the black dart pattern in his Sharingan immediately formed.

Kakashi then attached some Chakra on his feet and then he ran straight to the top of the Rashomon. After reaching the top, he presses his palm on the Rashomon.

A black seal is formed instantly, and the black dart pattern of his Sharingan is constantly rotating.

He is now imprinting the Rashomon gate with his Flying Thunder God Jutsu formula.

Kakashi leaped down and landed on the ground.

In the future, he might be fighting against Orochimaru again. And with this formula, he may be able to surprise attack Orochimaru.

After finishing this, he closes his Mangekyo Sharingan and then gently pulled the headband down.

Right now, Kakashi has been using Mangekyo frequently, and he was able to feel that his left eye's vision was gradually declining.

Although Mangekyō's blindness is not an imminent issue, it needs be solved sooner or later.

The Eternal Mangekyō Sharingan?

Kakashi is helpless, as he never heard Obito to have any brother at all.

Kakashi had previously suspected that Senjutsu might be able to delay Mangekyo's blindness, but now that he hasn't learned Senjutsu, he naturally doesn't know if his hypothesis is correct.

Only after he learned Senjutsu, that he can verify this thing.

Just as Kakashi wanted to leave this place, suddenly, the mural on the wall attracted Kakashi's attention.

"This is..."

Kakashi was startled as there seems to be some strange patterns in the mural.

Kakashi then walk to mural to take a closer look.

He then puts the oil lamp aside and the faint light illuminates the stone wall.

But this light is enough for Kakashi.

The mural is very large, as it covers the entire wall.

The picture looks very rough and he doesn't know who left it.

Kakashi looked at it carefully and suddenly, his eye went wide.

What is introduced on this mural are actually Three Great Artifacts!

Sword of Kusanagi! Yata Mirror! Yasaka Magatama!

"There are three Sword of Kusanagi in this world, one of the Sword of Kusanagi is in the hands of Orochimaru, and the second one is Sword of Totsuka, a variant of the Sword of Kusanagi that is wielded by Itachi's Susanoo. And the last one is Sword of Kusanagi that is wielded by Sasuke later."

Kakashi looked at the mural on the wall and quickly came to a conclusion.

In Kakashi's view, the real Sword of Kusanagi should be the Sword of Totsuka wielded by Itachi's Susanoo. As for Sword of Kusanagi that is wielded by Orochimaru and Sword of Kusanagi that is wielded by Sasuke, it is only a sharper sword.

Sword of Totsuka, Yata Mirror, and Yasaka Magatama are all Spiritual Items, objects that does not really exist.

Therefore, when it comes to power, the Sword of Totsuka is actually the most powerful among the three Sword of Kusanagi
