A few days later, outside the door of a room at a research institute in Konoha.

"Lord Natsuhiko, this is Orochimaru-sama's laboratory."

A female ninja with a good figure said to Xia Yan beside her.

"It's all said, just call me Xia Yan."

Xia Yan scratched his head a little helplessly.

Although he has been hiding at home for the past few days, with the visits of Kushina, Ichikaku-sensei, Fugaku and others, he still knows that he is very famous in Konoha because of the scandal with Tsunade.

And because of this scandal, all kinds of information about him have been dug up, and even the fact that he is a disciple of Mito Sensei has become known from a few people.

In the eyes of ordinary ninjas, Mito is basically a legendary-level figure, and Natsuhiko, as her last disciple, is naturally looked down upon because of this.

That's why the female ninja in front of him is so respectful to him.

However, Xia Yan, who has always liked to be low-key, still misses the days when girls were good to him because of his handsome face, not his identity.

"Then I'll just go in by myself here, thank you for leading the way."

Ignoring the flattering glances thrown by the other party, Xia Yan thanked and said goodbye to the female ninja.

After the female ninja reluctantly left, Xia Yan shook his head and smiled helplessly, and then knocked on the door of the laboratory in front of him.

In fact, Orochimaru had invited him here before, but at that time, Xia Yan couldn't go to the meeting because he went to find Tsunade.

Xia Yan, who originally had the idea of letting Orochimaru be a tool, was actually going to find an opportunity to talk to Orochimaru one day, but he didn't expect to receive Orochimaru's invitation again just a few days after he came back......

It didn't take long for a small crack in the door of the laboratory to be opened, and then a small purple-haired head that Xia Yan was slightly familiar with was slightly exposed, looking at him cautiously.

"Long time no see, little sister red bean."

Xia Yan waved his hand and greeted with a smile.

"Ah, the great evildoer...... No, it's the arcade owner! ”

Hongdou also quickly recognized Xia Yan and opened the door with a surprised face.

Except for studying sealing techniques in the research institute this vacation, she basically spent the rest of her time in the newly opened game hall.

So before Xia Yan set off to find Tsunade, Red Bean had seen him several times, so naturally he quickly recognized him.

It's just that she really couldn't imagine for a moment why this game hall owner and ninja school teacher would appear here.

At this time, there was a slight sound of footsteps coming from inside, and the two of them looked at it, and it turned out that Orochimaru, who had just finished the experiment, also walked over.

"I didn't expect Xia Yanjun that you and Hongdou also know each other, so you saved the time to introduce yourself."

Orochimaru said in his distinctive voice as he took off his gloves while looking at the two of them with interest.

And Hongdou suddenly felt a sense of foreboding at this time.

Then she heard Xia Yan laugh and say:

"Haha, Lord Orochimaru, you may not know, but your little apprentice is a frequent visitor to my game hall, especially Mu Dun vs. Zombies."

"Oh? Wood Escape vs. Zombies......"

Orochimaru glanced at the petrified red beans and smiled playfully.

"Red Bean, don't you keep saying that there is too much homework, so you don't even have time to rest?"

"It seems that you are just being modest, and there is absolutely room for more learning......

Azuki opened her mouth, but as a five-year-old human cub, she hadn't mastered the skill of quibbling, so she was speechless.

All she could do was curse Natsuhiko with a circle behind him as he walked into the lab.

"Uh, sure enough, this great villain is my lifelong enemy!

！ ”

And Xia Yan, who noticed the small movements of red beans, laughed secretly in his heart.

Let you, little girl, call me a big villain just now, do you think I didn't hear clearly?

And the tragedy of the red bean did not end there.

Because soon Orochimaru said again:

"Xia Yanjun, I'm sorry, I rarely have guests here, so I didn't prepare anything to greet you."

"- By the way, red beans, I remember you seem to have brought snacks for afternoon tea......"

……

After Orochimaru arranged a bunch of homework again, and then sent the red beans to the side to write homework, the two sat down, and there were two cups of tea and a few strings of three-color balls on the table.

After a few words of greeting, Orochimaru slowly spoke:

"Tsunade ......"

"Tsunade-sama and I are innocent!"

Before Orochimaru finished speaking, Xia Yan suddenly interrupted.

It's true that too many people ask him about this problem these days, and he has formed a conditioned reflex.

However, Orochimaru just smiled hoarsely and said, "Xia Yanjun, you don't have to worry, Tsunade has already told me." ”

"But you have to be careful, although Tsunade is not young, he has always been an idol in the hearts of many people in the village, and I won't be surprised if someone is looking for trouble with you because of this."

Orochimaru rarely looked gloating, and then pointed out: "But I don't think you need to worry about Xia Yan, except for a white-haired stupid person, I'm afraid not many people can really help Xia Yanjun you." ”

"After all, I've heard that Xia Yanjun, you can actually win or lose against that famous bounty hunter horn, it's really amazing......"

"It seems that you are a lot better than the last time you played with me, this speed of progress is really a bit scary, is Mito-sama's teaching level so high?"

Xia Yan waved his hand and said modestly: "Lord Orochimaru, you have won the prize." ”

"I only managed to resist Mr. Kakuto's attack with a few novel moves, and if it weren't for Tsunade-sama arriving in time, you might not have seen me now."

Orochimaru laughed noncommittally a few times before following the topic:

"It's just that I didn't expect you to meet Kakuto on this trip to Tsunade."

"Actually, I'm very interested in the rumored immortal body he has."

"So I don't know if you, Xia Yanjun, who actually fought with him, can you satisfy my curiosity?"

"Of course, in exchange, I will also provide some information that Xia Yanjun is interested in."

Xia Yan then understood that Orochimaru's previous words were all for this purpose.

Looking at his familiar appearance, Xia Yan knew that he had made such deals with others.

That's right, although Orochimaru thinks that ninjas are people who master ninjutsu, and therefore aspires to master all ninjutsu, but it is impossible to redevelop all ninjutsu by himself, and it is very reasonable and efficient to exchange ninjutsu or information with others.

And Xia Yan originally went to the appointment this time, but he actually had the same idea, so the two can be said to hit it off.

So Xia Yan was not hypocritical, and began to directly tell the story of his battle with Kakuto.

Of course, it's a cut version of Orochimaru's special offering, and only some of the details that help to understand the principle of Kakuto's so-called immortal body, and his actions are only a passing touch.

It can be regarded as the reincarnation of the Heavenly Dao, and Jiaodu took his information to exchange money for Xia Yan, which brought Xia Yan a lot of trouble, but this time it was Xia Yan's turn to use Jiaodu's information in exchange for benefits.

Although it was only part of the details, after listening to Xia Yan's story, Orochimaru couldn't help but stick out his tongue and lick his lips, and the golden vertical boy seemed to be glowing in the dim laboratory.

"It's an interesting idea to get immortality by taking someone's heart."

"Sure enough, there are too many mysteries in this ninja world that I don't know yet, I really don't know whether to be happy or sad......"

Then Orochimaru reviewed Xia Yan's words again, and then said thoughtfully:

"If according to Natsuhiko, those black tentacles in Nakakuto shouldn't be pure ninjutsu......"

Xia Yan nodded and said, "Indeed, those black tentacles are not so much ninjutsu as a strange creature that lives in symbiosis with the horns, just like ......"

"The oil girl's parasite secret technique......" Orochimaru added.

Xia Yan nodded and said that he thought the same thing.

Both of these techniques are to use one's own body as a vessel for some kind of creature to live in, and then use the chakra as a link to achieve a strange symbiotic relationship. ”

So Orochimaru, who understood the principle of the horn immortal body, suddenly lost his interest.

Obviously, this kind of half-hung immortal body is not what Orochimaru wants.

"It seems that although the immortal body of this horn capital is still genuine, it may not be so easy to achieve true immortality......

Orochimaru looked at Xia Yandao and said, "Xia Yanjun, do you know why?" ”

Xia Yan hesitated slightly, but still said bluntly: "Is it the soul?" ”

Orochimaru's eyes lit up when he heard this, and he laughed again:

"It's really worthy of Xia Yanjun, and he really knows this."

"Very few people know the fact that in addition to the aging of the body, the soul opposite the body is also aging slowly."

"It's just that almost all people have reached the limit of their bodies long before they die of soul failure, so they don't know this fact."

"And in the ninja world, although there are many legends of immortal bodies, they do not involve the realm of the soul at all."

"Even if you live for hundreds of years with the immortality of your body, you will still die due to the exhaustion of your soul, and you will not be considered a real immortal body."

Listening to Orochimaru commenting on Kakuto's immortal body, Xia Yan inexplicably had a wonderful sense of déjà vu.

What kind of snake aunt is this tea pill theory that does not die?

Sure enough, Orochimaru then sighed with emotion:

"The only people who really have the opportunity to set foot in immortality are people like Xia Yanjun and me who understand the importance of the soul......

God, there was no thunder.

So Xia Yan's hand didn't tremble when he picked up the tea, and after taking a sip, he said with a little speechlessness:

"Orochimaru-sama, I haven't thought so far for the time being, after all, I'm not yet twenty, and immortality is too far away......"

"By the way, Orochimaru-sama, you're only in your early thirties, so you don't need to be in such a hurry......"

"Hehe, if you wait until you're old, I'm afraid it's too late to think about it......"

Orochimaru, who also seemed to feel that he had just lost his temper, ended the topic with the above emotion.

Then he took a sip of tea before smiling slowly.

"Even so, the information you provided is still very interesting, Xia Yan."

"Then next, it's Xia Yan's turn, I don't know what you want to know?"

It's finally him.

Xia Yan thought to himself, in fact, it is quite appropriate to follow the topic of the soul and ask about the knowledge of spell marks, but with the scroll given by Mito-sensei, there is no need to take such a risk.

So Xia Yan still asked the question that had been prepared before:

"I don't know if Orochimaru-sama, have you ever heard of a ninjutsu that absorbs chakra?"
