There is no direct border between the Land of Fire and the Land of Thunder, and there is only one path that connects the two great powers, and this path is used for business between caravans.

And there are two small countries between the land of fire and the country of thunder, but Kenichi Amamiya doesn't plan to go over there, he plans to go directly from the country of iron, and by the way, he also searches the graves of the golden horn and silver horn.

Golden Horn and Silver Horn Amamiya Kenichi are still very interested, he is not interested in the strength of the other party, but the bloodline of the other party, as the bloodline of the Six Dao Immortals, and at the same time those artifacts of the Six Dao Immortals.

So going to the land of thunder was also what Kenichi Amamiya had planned before, but this time it happened to be a test of the power of the thermobaric bomb, so it was solved together.

As for whether blowing up the Land of Thunder will cause any problems? Amamiya Kenichi doesn't care, anyway, there is Konoha to blame, he is just a war mercenary for money, it is difficult to say that when the time comes, he will still receive an order from Yunyin Village, go to Konoha and throw one.

"Scorpion, have you ever been to the Land of Iron?" Kenichi Amamiya sat on the boat, looked at the scorpion next to him and asked.

"No, I've only heard that it's a permanently neutral country, and several wars haven't affected that place." Scorpion shook his head, he was fiddling with his first machine.

The metal used in the decapitation knife is very unique, and it has the ability to absorb iron in the blood to repair itself, so the scorpion plans to melt the decapitation knife and make it into the armor of his first machine.

Amamiya Kenichi agrees with this approach of the scorpion, after all, the decapitation knife is indeed very strong, but it seems to be made of meteorites that fell from the sky, and I don't know if there are other metals with the same properties in the ninja world.

"Scorpion, although it is said that the metal used for the decapitation knife has this property, you also need to pay attention to the fact that sometimes the same raw materials, and as a result, after changing some firing methods, the things obtained may be different." Kenichi Amamiya reminded.

This is the experience of Kenichi Amamiya, who once used a stove to burn the materials that his mentor needed, and as a result, the three stoves had exactly the same firing method, and only one succeeded, and the other two were scrapped.

So materials science is actually very metaphysical, this thing is very magical, and sometimes it may even burn something terrible under particularly outrageous circumstances.

Before the crossing, one of Amamiya's senior brothers had daydreamed that if he could burn a furnace of room-temperature superconducting materials, what would happen.

At first, Kenichi Amamiya wanted to persuade his senior brother to stop dreaming, but then he felt that if it really burned out, then it would really be bad.

The disadvantage is how to reproduce it again, and the temperature and humidity must be accurately controlled, and even the angle when putting it in, mood problems, etc.

"Hmm." The scorpion naturally knew this, but he felt that this metal should be relatively stable, so that it would not become another property after being burned.

"O Iron Country, what a peaceful country." Amamiya Kenichi smacked his lips, he felt that he was a little bored, the ninja world was actually quite big, and it took a lot of time to hurry.

What's more, he didn't know if there were other cities on the other side of the sea, after all, no one in the ninja world had ever been to the ocean.

[Current research subject: Chakra parasite]

[Research progress: 5.72%]

Amamiya Ken looked at his research progress, this research progress is a little slow, but Amamiya Kenichi didn't care, this ancient parasite can be studied very well, but I don't know what will be studied in the end.

"Kenichi, I heard that you are a disciple of Orochimaru?" The scorpion suddenly raised his head and asked, and Amamiya Kenichi also nodded directly, he was indeed a disciple of Orochimaru.

"Is your teacher a woman?" The scorpion looked at Kenichi Amamiya curiously, his eyes full of curiosity.

“？” Kenichi Amamiya slowly knocked out a question mark, what kind of strange question is this?

Although it is said that the teacher has indeed used the immortal reincarnation to become a woman now, he is not still Orochimaru, but his identity is indeed a woman.

But how does the scorpion know? The secret ninjutsu teacher of the immortal reincarnation has never revealed it, and he has only been exposed to some clues of the immortal reincarnation, and the others are also unaware, such as how to perform this forbidden technique.

The teacher didn't teach me, and I don't know if I didn't want to teach or if I was prepared.

"Before, the leader told Xiao Nan that he didn't expect that Orochimaru, one of the three ninjas in the ninja world, would be a woman, I heard it." The scorpion saw Amamiya's doubts, and then explained in passing.

The corners of Amamiya Kenichi's mouth twitched, I didn't expect Nagato to have this ability, did you notice it when you pulled the teacher in to talk?

"Ah, teacher... It's a girl, indeed. Amamiya scratched his head, and then thought of the blonde-haired girl he had seen in the base.

I have to say that Yuqi's appearance is still very high, but it's a pity that the soul of the body is now Orochimaru.

But when it comes to this question, Kenichi Amamiya remembered another thing, that is, the teacher's previous performance was a little feminine, was this affected by the body?

Will she really become a woman in the future?

What is this, Uncle Snake has become Aunt Snake, right?

No, since the age is younger than himself, Uncle Snake has become a snake sister?

Thinking that the teacher would come to relatives, Amamiya Kenichi shook his head violently, thinking that that scene was too terrifying.

"One of the three ninjas, Orochimaru, turned out to be a girl? This is shocking news. The scorpion smiled slightly, and then glanced at Kenichi Amamiya more.

Amamiya Kenichi looked at the scorpion suspiciously, what is the matter with this guy looking at him?

"Let's go, the Iron Country has arrived." Kenichi Amamiya shouted, the dock of the Iron Country has arrived, and they still need to go ashore, and then go to the Land of Thunder through the Iron Country.

And Kenichi Amamiya's identity is an ordinary businessman, which is the most convenient way to enter and exit other countries, and the disguise made by the art of eliminating Yan is also very real, so there is no need to worry about any problems.

The inspection of the Iron Country is relatively much lax, and after giving a bribe of one thousand taels, Kenichi Amamiya directly exempted the inspection procedure and went in directly with the scorpion.

"It seems that the long period of peace has brought some changes to this country, which I don't know if they are good or bad." Amamiya Kenichi smacked his lips, what if there was a thermobaric bomb in the goods he carried?

But it's good that way, at least it's convenient for Kenichi Amamiya to do things.

"This kind of country—" The scorpion shook his head as well.
