Jiraiya rummaged through the bag, took out the scroll and threw it to Naruto, and said, "Be careful, it will unseal." ”

"Well, it won't." Naruto replied honestly, Amaterasu is not afraid, the orange fox armor can resist, and he really can't solve the fire seal.

Jiraiya: "......"

Why do I want to smoke you to death, you can't even solve this after studying for so long?

He sighed and said, "Introductory Book 7, page 777, check it yourself." ”

"Oh." Naruto poured out a pile of books from his sealing scroll and flipped through them for a moment before finally pulling out a thick, scary book.

This is also one of the reasons why Naruto can't learn it, there are ten volumes in total, and each volume has a minimum of 1,500 pages, which is thicker than a brick.

I don't know if opening these books can purify the mind, but closing them is definitely enough to open people's brains.

Naruto had always wondered if the Uzumaki clan had some misunderstanding of the word "entry", how could there be such a thick introductory textbook.

Seeing Naruto's study in that pit, he couldn't get angry, and at this time, his inspiration was broken, he dropped his pen, and said solemnly: "Send me to the Fire City, I want to take materials." ”

Naruto looked sideways, how did you old pervert talk about such a thing as voyeurism so seriously?

Sending Jiraiya away, Naruto also left with all his belongings.

After sending the other three to the Land of Snow to help plough the ground, and the other three to Mt. Myogi, Naruto found a quick clearing, first uprooted the tree, and then tamped it with Mo Evil Treasure bricks.

Then, let the doppelganger buy aluminum powder and iron oxide for thermite making, which are not difficult to buy, as long as there are mines at home.

In the end, I went to Konoha to pick up Shikamaru again.

The sunglasses plan requires a lot of calculations, lighting, and stacking angles, although Naruto's computing power is okay, but it can't reach the supercomputing level, so I can only ask Shikamaru.

After briefly explaining the sunglasses plan, Shikamaru squinted at the sun, Naruto's plan made him feel refreshed, but, "It's too troublesome." ”

If I have to calculate the light collection rate, the refractive index of air to sunlight, and the corrosion of wind, sand and rain, and other uncertain factors, should I tell him to build another pure glass isolation room? But looking at him like that, he has to calculate the construction of isolation houses by himself, which has to be considered more, hey...

Shikamaru looked up to the sky and sighed and said, "You can't do it here." ”

"Then another one." Naruto put his hand on his shoulder and started the teleportation.

After a few minutes, Shikamaru grabbed his arm, bent over and retched: "Stop, stop, stop." ”

Within a few minutes, Naruto flew to several countries with him, unlike Naruto, who was used to passing dozens of times a day, Shikamaru had just come into contact today, and he was not familiar with it, so he was going to vomit.

"Can't do it? Or outer space. ”

"Can you still go to outer space?" Shikamaru looked at him in surprise.

"It should work." Naruto replied, using the orange fox chakra to defend, and then letting the clone use Tiyun to jump up infinitely to open up the field of vision and teleport, theoretically it should be able to jump into outer space, but I don't know how many clones will die, and it takes a bit long.

"It's getting better." Shikamaru sighed, his eyes swept around and said, "This piece is about the same." ”

"Then you do the math first, I'll level the land."

After more than an hour, Shikamaru handed over a dozen drawings and said, "That's probably it, if you encounter any problems, you can refer to... Never mind. ”

Shikamaru thought about it and forgot it, he would definitely come to him again when the time came.

"Thank you."

"You're welcome, don't call me next time." Shikamaru yawned and said, "It's not too early, I'll go back first." ”

Shikamaru is gone, and the doppelganger who bought the materials is back, and Naruto splits into two venues to release the whirlpool construction team that has just been laid off at the Ghost Lantern City Theater and has been re-employed.

As for why there are so many employment opportunities, it may have something to do with the fact that they all have nine years of compulsory education.

The construction team was divided into two teams, the second team of 300 people to build sunglasses, the first team of 200 people to configure thermite, and an elite team responsible for grinding Mithril powder.

The sunglasses plan at the No. 2 construction site is relatively novel and interesting, and the doppelgangers are full of energy and processed according to the drawings, and the dry is in full swing, and there are no casualties.

And the No. 1 venue, the heat can't express the situation at all, to use fanaticism, that scene can only be described in four words - the palace of art.

"Boom!" "Boom!" "Boom!" ……

Two hundred doppelgangers dressed in trumpet uniforms seemed to have received some kind of mysterious aura bonus, holding experimental equipment and doing a rough Ming style matching method, measuring the amount, putting in the equipment and heating it, and then the fried Jiu Sinai didn't know it.

The consequences of not knowing the ratio of thermite are terrifying, small ones are burns, heavy ones are severe, and the doppelgangers, they don't hide at all, in their words, this is a sacrifice for the sake of noble art.

But they are not the happiest ones to be fried, the happiest are the elite teams that grind Mithril powder, everyone is playing, and we are doing such annoying work, it is better to die and change teams.

And this kind of chemical explosion, and human bomb, like the war-torn Middle East, Naruto still calmly sat on the sofa and studied.

From time to time, I threw two ghost lamp fruits in my mouth, that is, girl fruits, to relieve my irritable mood, but I really couldn't relieve it, so I threw away two spiral shuriken.

Two days later, in the afternoon, Naruto finally unlocked the Fire Seal, which was only a one-time version, and this seal was completely destroyed, and if he wanted to seal Amaterasu again, he could only let Jiraiya draw another one.

After countless deaths, he also created thermite, but it had no way to do Mithril.

Mithril, a metal that only exists in fantasy, is difficult to melt in addition to the matching furnace, and even the sunglasses can't be melted because of the area problem.

Fortunately, Amaterasu, the legendary flame, can melt, but it melts slowly, so Naruto used the powder method plus Amaterasu to speed up.

Grabbing a large handful of powder and throwing it into the pitch-black flames, Naruto stood on the scaffolding, red chakra paws in both hands reaching into the flames and stirring them to heat it up fully.

Finally, he took out the blue liquid Mithril, skimmed off the black flame on it, and threw it back into the fire along with the chakra claw, and poured the liquid into the prepared container.

Amaterasu is really strong, even the Nine-Tails Chakra can be attached to burn, but Naruto doesn't care, anyway, the Nine-Tails Chakra is so much that he doesn't know how to use it, so he doesn't need to use it in vain.

Looking at the small pool of liquid, Naruto's heart was greatly satisfied, this strong and refractory metal could be regarded as melted by him.

Suddenly, his head flashed, and he looked down at the backs of his hands, if he beat this pool of liquid into his bones, with his own recovery power, would he die?

Shaking his head and giving up this method of death, Naruto hurriedly sealed the liquid Mithril and let the clone give it to Tiantian.

After that, he opened Jiraiya again and sealed the remaining Amaterasu.

Jiraiya said to Naruto with a cross eyebrow while drawing the Fire Sealing Seal, "If you don't learn, you can't do it." ”

You can break the seal so much that you can't repair it, why don't you tear it up.

"Hey, hey." Naruto took out the scroll with the dragon's life reincarnated on it and handed it to him, "Old man, do me a favor." ”

"What is this?" Jiraiya opened the scroll, looked at it for a while, and then began to change his face, shocked, trance, dazed awakening, thinking, and so on, and finally couldn't help but praise: "This is a genius, no, this is a madman." ”

It was the first time he knew that there was such a ninjutsu in the ninja world that sacrificed himself to resurrect others.

"So what are you going to do?" Jiraiya continued to look at the scrolls, which had a lot of things that interested him.

"I want to know how to terminate the process of delivering life force to it."

I don't know if the ninjutsu of Dragon Destiny Reincarnation has no end at all or the inventor's technology is not enough, once it starts to be transported, unless the vitality is exhausted, it can't be stopped at all.

This is not what Naruto wants, if this can't be stopped, then isn't it just that I'm dead, and Spiralmaru is alive.

So Naruto wants to change, but he has self-knowledge, whether it is inventing ninjutsu or transforming ninjutsu, it is the exclusive domain of the school masters, such as Orochimaru, Hinata, the second generation, etc., and the scumbag wants to invent ninjutsu, and there is only one result, and one dies faster than the other, for example...... Nine seconds to die.

"Okay, go back first, and then you go and get the fish cakes." Jilai also put away the scroll and said with a wave of his big hand.

He was really interested in this, and the fish cake could bring him more inspiration.

………

Five days later, in the woods, Jiraiya sat around the fire, petting the cat while watching Naruto practice injecting life into the spiral pill, and if something went wrong, he would interrupt.

Although Jiraiya used to be a crane tail, but after many years of ninja career, the amount of knowledge is no worse than that of Xueba, and five days is enough for him to improve this ninjutsu.

After all, it's just an interruption, not a reversal.

Naruto stood on his knees, his hands in front of his abdomen, controlling the flow of life force in his body driven by Chakra.

But within a few seconds, the Spiral Pill was on the verge of collapse, and Naruto had to use his roar to increase his control: "Drink... Yes. ”

"Bang."

The yelling was useless, and the spiral pill still exploded.

The pure vitality that is invisible to the naked eye is scattered, and Xiao Lingtong, who has been waiting for a long time, rushed over and sucked it hard, for fear of wasting a little.

The spirit world poured Coke to replenish his vitality, and Naruto began a second experiment.

In the blink of an eye, ten days had passed, and Naruto's new technique was close to success.

I don't know how many experiments, Naruto finally held a milky white spiral pill and said happily, "old man, how is it?" ”

Jiraiya sensed the danger and instinctively took two steps back, this move was called a spiral pill by Naruto in medical ninjutsu, and he always felt like he had received... will die.

Pointing to the experimental wild boar next to him, he said, "You try it first." ”

"Okay." Naruto walked over to the three-hundred-pound boar and single-handedly struck the spiral pill into his abdomen.

The powerful thrust of the spiral pill pushed the wild boar backwards for more than ten meters, and finally exploded, the rich vitality was scattered, absorbed by the grass, and the wild grass rose like crazy, quickly burying the wild boar.

Look at the height, the lowest is also a zhang high.

And the wild boar, which was still breathing just now, is now motionless, and even its breathing has stopped.

Jiraiya: "......"

The difference between this move and ordinary spiral pills is that you can plant a circle of grave grass around the enemy's corpse?

"Well, that doesn't make sense." Naruto held the blue spiral pill and walked towards the next wild boar with a confused expression.

How can a skill that is full of life force be killed? This is a ninja.
