"Naruto, there's no way to mark the Flying Thunder God on the big iron door that seals the space, even though it looks like it's in kind..."

It was already late at night, and Bo Feng Shuimen was standing next to the paws of the Nine Lamas, explaining to Naruto.

After leaving a word for Shikamaru, Naruto went straight home, as there was no point in staying there.

And according to what Shikamaru said before, he will often come to Naruto in the future, because Hokage-sama still needs him to report the situation, so he will not be able to try to practice Flying Thunder God over there.

After returning home and having lunch at noon, he has been studying his famous stunt Flying Thunder God with his father in the seal.

Until now, Naruto is still thinking about the principle of the Flying Thunder God's technique.

The Flying Thunder God's technique is a space-time ninjutsu.

In the world of ninjas, space-time ninjutsu is actually very common, such as psychics.

Spiritism, a time-space ninjutsu, is not reasonable at all, it can allow the ninja to communicate with each other directly regardless of the dimensional space after the psychic beast signs a blood contract with himself.

Nagato in the ninja world can channel the ten-tailed shell in the inner core of the moon in the sky directly to his side.

And similar psychic images were seen a lot when Naruto watched the Hokage in his previous life.

For example, in the early stage of the animation, you can see that the toad of Myoki Mountain can be summoned to Konoha by Jiraiya and Naruto, and in the later stage, Naruto can also be summoned to Myoki Mountain by the toad reverse channel.

There are also the two storage scrolls on Naruto's body now, which themselves are also used in the realm of time and space ninjutsu, and they are the simplest.

As long as a ninja carries this scroll with him, he can enter the chakra to summon and take out the ninja equipment stored in advance from the scroll, and seal it back afterwards.

Konoha is the most representative figure every day.

Of course, Naruto felt that the strongest psychic technique was definitely Dirt Reincarnation.

This forbidden technique, developed by the second generation Hokage, can even break the boundary between life and death, take advantage of the loopholes of the rules of reincarnation, and directly summon the souls of the dead into the present world.

Flying Thunder God is more inclined to be a kind of use of reverse channeling in the field of time and space ninjutsu, but the key in the psychic process is not blood, but Chakra, and the object of the contract is himself.

The whole process of casting the spell is through his own chakra, and after perceiving the coordinate technique, he channels himself to the marked position.

The second generation of Hokage has developed a unique principle of psychic magic for the Flying Thunder God after the psychic operation, and it also combines the teleportation technique and the sealing technique in the casting process.

First of all, the most important condition is to perform the Flying Thunder God Technique, which requires extremely high personal perception ability.

The main reason why Naruto's father's three exclusive guards couldn't master the Flying Thunder God was because of their poor perception.

After the three people were disassembled, they couldn't accurately lock the magic marks they had done through their own perceptions, so they could only use stupid methods to link the perceptions of the three people to the same frequency, and then cooperate with each other to reluctantly cast the Flying Thunder God Array.

Therefore, another prerequisite for casting spells is that when activating the Flying Thunder God, you need to mark the spell in the moving area.

It should be said that it must be marked first.

This mark of casting the Flying Thunder God is generated by his own chakra, and at the moment of leaving the mark, he must simultaneously cast the sealing technique to completely complete the mark.

The coordinate technique left in this way will never disappear, and in this regard, during the last ninja war of the Naruto anime, Bo Feng Shuimon specifically emphasized to Uchiha Obito.

However, after Obito became the Ten-Tailed Human Pillar Force, he reshaped his physical body and destroyed the Flying Thunder God magic mark sealed on his body.

Combined with the memory content passed on to him by his father Bo Feng Shuimen, it seems that when he first started to study the Flying Thunder God, he had no guidance, and he was delayed in perceiving and understanding the magic runes.

However, his talent was very high, and with the help of his mother, Vortex Kushina, he quickly became a Flying Thunder God by learning a large number of unique sealing techniques and many unique cultivation methods in perception of the Vortex Clan.

According to his father's statement, Naruto now has a huge chakra advantage and has mastered his perception ability, and he can also use the sealing technique, and he has also taught him the psychic technique about the core of the Flying Thunder God.

Now what he has to do is very simple, first make a surgical mark in the position he wants to move to, and then perceive the chakra in the surgical mark that he has left, as long as it resonates with the chakra in the surgical mark, he can be instantly channeled by the special reverse psychic technique in the surgical mark.

After Naruto felt that he had reached the conditions for entering the Flying Thor, he originally planned to go to the mirror world to challenge his father's data puppet, wanting to experience what it was like to face the Flying Thor.

As a result, he found that he couldn't challenge his father's data puppet of Bo Feng Shui Men to suggest that the data of related characters was insufficient.

Then he wanted to try to mark the magic mark on the puppet when he challenged the other puppets in the mirror world, and planned to directly use the Flying Thunder God in battle.

But once he uses the shadow clone to beat the puppet and wants to make a mark, the battle will be inexplicably forced to end.

The prompt sound is like being poisoned, and it has been brushing to improve the relevant data.

After discovering that it was impossible to practice the Flying Thunder God in the mirror world, Naruto turned his attention to the sealing space.

In the sealing here, Naruto made an attempt, and the ninja kunai and the like can be projected in, and other ninjutsu that he knows can also be used in the sealing space.

Then he set his sights on the Seal Gate.

He tried, and the gate could be attacked by ninjutsu, and he could also use kunai to spark sparks.

But it just can't mark the magic mark of the Flying Thunder God.

So at the beginning, Bo Feng Shui Men explained to him that this iron door was not actually a physical object, but just a thing that was embodied by sealing.

"Looks like we'll have to find a chance to avoid the surveillance," Naruto thought of and decided to put aside the practice of Flying Thor for the time being.

After thinking for a while, Naruto walked over to the side of the Iron Gate Ribo Feng Shui Gate and asked, "Father, now let's study how to add attribute changes to the Spiral Pill."

An embarrassed look flashed on Bo Feng Shuimen's face and said, "Well, Naruto, in fact, I have been researching adding attribute changes to the Spiral Pill before I was alive, and I have also consulted Jiraiya Sensei for this."

"It's just that Mr. Jiraiya, who also learned the Spiral Pill, didn't do it, and then we thought about using the blessing of the fairy art to see if we could forcibly break through this barrier, but I was already a Hokage when I learned the fairy arts, and the time to go to Myoki Mountain is really limited"

"You also know what happened later, I didn't have time to delve into how to add attribute changes to the Spiral Pill"

"So how to add attribute changes to the spiral pill, you and I are actually at the same starting point"

Naruto's heart sank when he heard this, he knew that his father's idea of using senjutsu was right.

In the original book, although Naruto finally took advantage of the change in the nature of the Wind Escape Chakra to upgrade the Spiral Pill to the Spiral Pill Shuriken, the Spiral Pill Shuriken at this time was actually only 50% completed.

Not to mention that the state cannot be stabilized, it is necessary to attack at zero distance, and the side effects of hurting others and hurting oneself are extremely great.

Later, after Naruto went to Myoki Mountain to learn immortals, the spiral pill shuriken in the immortal mode finally had no shortcomings, and could be thrown perfectly, and the completion of attribute changes was only 100%.

Today's unfortunate things are really one after another, and if you continue like this, you will have to plan for the next cultivation plan again.....

"Heh~ Four generations of Hokage, that is, you are so complicated! Why don't you further strengthen it on the basis of the Spiral Pill and take a look, just like the Tailed Beast Jade that our Tailed Beast spits out, the more chakra, the greater the power of the Tailed Beast Jade"

The Nine Lamas, who were lying on the side, suddenly stretched their paws and sat up as they spoke.

"Uh.... It takes a lot of chakra to continue to strengthen on the basis of the spiral pill like the tailed beast jade, my chakra...."Bo Fengshuimen was stunned, and he suddenly thought that his son's situation was completely different from his own.

His own son has the physique of the Vortex Clan, and he has no shortage of chakras at all.

Naruto's eyes lit up when he heard this, what the Nine Lamas said was completely feasible, there was a Spiral Pill in the original book, and after strengthening it on the basis, there was an advanced version called the Great Jade Spiral Pill.

The Nine Lamas had already told him how the Tailed Beast Jade was condensed, and Naruto immediately took action when he thought of this, and in the blink of an eye, a fist-sized spiral pill was condensed in his palm, and then he began to gradually inject more chakras into the form of the existing spiral pill.

In the sealing space, the spiral pill in Naruto's hand became bigger and bigger, and soon the volume rose to the size of a football, and it seemed that it was going to rise more and more.

Seeing this, a strange thought flashed through Naruto's heart, and he suddenly controlled the chakra inside the large spiral pill to begin to compress the density of the spiral pill in the same way as condensing the tailed beast jade.

Bo Fengshuimen realized that the situation was wrong and was just about to speak, but the nine lamas on the side immediately popped out a piece of fingernails to signal him not to interrupt.

The large spiral pill in Naruto's hand shrank rapidly, and after a few breaths, the entire spiral pill was suppressed by him to the size of a fist, and then the spiral pill went black.

Under Naruto's perception, the density of the chakra inside the thing in his hand, which he didn't know if it was a spiral pill, had been compressed to an unimaginable level, and the black sphere was still surrounded by several rings of irregular motion.

These halos are like the rings of planets that he has seen in science fiction movies in his previous life, and the rings of matter that revolve around the planets form a ring.

"What kind of spiral pill is this?"
