Flying Thunder God Technique Analysis

Namikaze Minato replied, "Indeed, I've had this technique for quite some time now, and I've made many improvements over it, requiring extensive practice before I could use it in actual combat."

"Where to begin? Hmm... let's start with the principle behind the Flying Thunder God Technique!"

"Shuichi-kun, you must have used the Summoning Jutsu many times by now, right?" Minato said, forming hand seals. "Boar-Dog-Rooster-Monkey-Sheep, then use your Mental Energy to call out the name of the corresponding summoning Summoning Beast in your mind, and you can summon it."

"If it's just a matter of simply outputting chakra, then one of the Summoning Beasts in the blood pact that meets that chakra requirement will be randomly teleported over."

Shuichi moment and then said, "So, the Flying Thunder God Technique is like Reverse Summoning yourself in reverse?"

"That's another way to explain it. I suspect that the Second Hokage also drew inspiration from Summoning Techniques and then improved upon them using Fuinjutsu." Minato paused for a moment, then began to organize his thoughts to explain this somewhat complex principle.

"There's a clear difference between the two. Summoning Technique uses a large Contract Scroll to lock the two ends of the teleportation. For example, using the Mount Myōboku Contract Scroll, we leave our blood as a location, while the Summoning Beast uses its chakra as a location. This way, the spatial channel for teleportation is fixed..."

"The Flying Thunder God Technique involves movement via a jutsu, with the other end being one's own chakra. Therefore, teleporting us, who use chakra, to that chosen location involves some complex Fuinjutsu techniques..."

Shuichi listened carefully to the description, and to make it easier to understand, he kept recalling various knowledge from his previous life to find similar situations. With the speed of his brain's thinking, he quickly understood Minato's meaning.

This can be illustrated by the analogy of making a phone call to transmit a message. First, there's the principle of Summoning Technique: the telephone line (spatial channel) already exists, which is essentially a large Contract Scroll.

At this point, both ends of the call are fixed in place, and the ninja can make a call to summon the Summoning Beast can then summon the beast to complete the summoning.

The Flying Thunder God Technique is different, involving two key points, the first being perception.

If you can't sense chakra, it's like there's no one on the other end of a phone call; of course, there's no way to transmit it.

The second is to establish a telephone line (space channel). Since there is no Contract Scroll, this telephone line must be temporarily set up. In addition, since the person being séance is the caster himself, it will cost money twice.

"So that's how it is! That's how the Flying Thunder God's chakra consumption is calculated!" Shuichi suddenly realized, and immediately understood many aspects of the Flying Thunder God in the original work.

When activating the Flying Thunder God, the cost for connecting the phone (opening the space) is based on the size of the device. Taking the Toad with you is equivalent to summoning the Toad and yourself to the location, and this is the first cost (chakra).

Next is the length of the telephone line (space channel). The farther the distance, the more chakra is consumed. Since Shuichi has not yet learned the Flying Thunder God Technique, it is uncertain how much this part of the consumption is, but it should not be too much.

"Therefore, to successfully use the Flying Thunder God Technique, three things must be accomplished in that instant." Minato held up three fingers. "First, open up space; second, construct a spatial passage; third, use chakra to activate the Ninjutsu."

This is the first difficulty of the Flying Thunder God, which can be described as a simplified version of multitasking. Shuichi finally understood what the Flying Thunder God Formation of the three guards was all about.

The Fourth Hokage prepared Kunai with the technique formula for them. One of them injected chakra into the kunai beforehand to locate and sense the space. Then, the three of them held hands. The second person constructed a spatial channel, and the third person output chakra. By completing this process at the same time, they could teleport away anything they touched (or touched by chakra).

"I understand, that's roughly the principle..." Shuichi explained his understanding, making sure there were no inaccuracies.

After listening, Minato exclaimed in admiration, "As expected of Shuichi-kun, you understood completely after I only said it once."

After a pause, he handed the Trident Kunai Shuichi and continued explaining the Flying Thunder God: "I'll talk about perception range and precise positioning later. Now, let's discuss some precautions for actual combat."

"The first and most important issue is that the Flying Thunder God Technique can be seen as another form of Body Flicker Technique, with speeds approaching the limit, but this also comes with corresponding risks." Minato's expression turned serious at this point. "This is also why I'm unsure if the Flying Thunder God is suitable for you, because you can't use Ninjutsu for the instant after using Flying Thunder God; you can only use Taijutsu."

"Hmm?" Shuichi thought for a moment, not rushing to explain why he was able to teleport while using the Rasengan in the original story, but instead offering a guess. "I think there are two reasons, one is the interference of spatial pressure on the body, and the other is the problem of the chakra flow path within the meridians."

"I didn't feel any spatial pressure, but the circulation of chakra takes time. The Body Flicker Technique involves unleashing chakra in the legs and then landing, while the chakra flow path of the Flying Thunder God Technique should be similar to that of the Summoning Technique." As a master of the Body Flicker Technique, Shuichi easily noticed the risks involved.

"Such rapid movement will inevitably lead to more severe stiffness, equivalent to landing in a state where the previous Ninjutsu hasn't finished, so of course you can't use the next Ninjutsu."

"You're absolutely right." Minato found the communication with him unusually smooth. "One meridian cannot activate two Ninjutsu simultaneously, especially Nature Transformation Ninjutsu; it can easily lead to serious conflicts."

Shuichi finally understood why only the Second Hokage and Fourth Hokage Flying Thunder God in the original work. It wasn't that the other members of the Hokage lineage couldn't learn it, but rather that there was no need for them to learn it, as it had absolutely no practical value for them.

Focusing all your attention on the Flying Thunder God Technique will leave you stunned for a period of time after teleporting, while the location of your Kunai will also tell the enemy where you're going. In a fight between opponents of the same level, this is practically suicide.

People like the First Hokage, the Third Hokage, Jiraiya primarily used Ninjutsu. It was always safer to defeat enemies from a distance than to fight them in close combat. Even someone as skilled as the Second Hokage would only use it as a last resort for a surprise attack.

"So this technique isn't really suitable for you, because you already have multiple Nature Transformation Ninjutsu you can use, and there's some conflict between the two," Minato said somewhat embarrassedly. "Besides Fuinjutsu, I usually train extensively to adapt my body to space-time manipulation and hone my Taijutsu before I can use it in actual combat."

"If I move too many times in a short period of time, I need to stop and form hand seals to maintain the flow of chakra and relieve the pressure on myself."

This hand seal is the "Unfinished Seal," used with one hand. It's the seal used to finish off Summoning Jutsu. Shuichi noticed that this matches Minato's performance in the original manga. As for why this action wasn't needed in the Fourth Shinobi War, it seems to be due to the Edo Tensei Body and Sage Mode.

It's understandable that he was able to use the Rasengan within a limited time two years later; everyone improves, let alone a genius like Minato.

The use of Flying Thunder God while maintaining Rasengan is somewhat similar to Shuichi's previous Chidori: Second Stage. Both involve bursting out Body Flicker Technique in a very short time before unleashing Chidori, and are the result of continuously improving chakra control.

"The above covers the practical application of the Flying Thunder God Technique. In the past two years, to compensate for the limitation of the Kunai's position being targeted, I have been constantly practicing using Fuinjutsu to quickly apply spells to the enemy, thereby enriching my offensive methods..."

The technique of instantly imprinting the mark is the core of unleashing the power of the Flying Thunder God Technique. It is also the qualitative change brought about by Minato's years of learning and research into Fuinjutsu. Even the Second Hokage needs time to imprint a mark on someone. In actual combat, it is better to take advantage of this opportunity to stab the enemy.

Therefore, Minato's current offensive strategy involves alternating between the Flying Thunder God and the Body Flicker Technique. When close to the enemy, he uses his excellent Taijutsu to attack and kill them or silently leave a mark, waiting for the enemy to lower their guard before delivering the final stab.

"That's why I made the Kunai like this." Minato took out Trident Kunai and slashed it. "This weight is incredibly powerful at close range, and the angle between the three spikes can also block the slashes of a long sword..."

This was designed based on his own fighting style. The Second Hokage was mainly used for surprise attacks, so it was disguised as a regular Kunai as much as possible. His fighting style, which mainly used the Flying Thunder God Technique, required him to pick up and throw kunai while fighting, so as to ensure that he always had the ability to kill with one blow.

"Hmm..." Shuichi for a while. Minato had explained it very clearly, but then he remembered that there was still an unsolved mystery in the original work: perception and movement distance. "Right, if that's the case, then the Flying Thunder God Technique can go wherever it wants, as long as I leave the incantation wherever I go..."

Minato gave a wry smile after hearing this. "Shuichi-kun, you're overthinking it. This is precisely the last point I wanted to tell you: the relationship between perception distance, the secrets of the technique, and chakra levels. If this technique truly had that effect, the Third Lord and the others would have learned it long ago..."

First, Kunai. After tearing off the paper with the incantation on the handle, Shuichi discovered that the material was exactly the same as the one used for Explosive Tags, both capable of storing chakra for a long time.

However, as time goes by, the chakra inside will decrease and it will soon lose its effectiveness, requiring a refill of chakra to take effect.

"The timeframe is roughly between one day and one week. By making slight adjustments to the surgical technique, I can get a general idea of what to expect," Minato explained to him.

"How could it be so short? The Explosive Tags should have a long shelf life, right?" Shuichi was very surprised.

"Because this technique actually releases chakra continuously, the caster can sense it," Minato pointed to the paper with the technique inscribed on it. "Once the chakra is used up, it can no longer be sensed."

"This is a technique stored on Chakra Paper. If the technique is inscribed on a living person, it won't easily disappear, but the sensing range is very limited..." His expression became somewhat conflicted. "The principle comes from sealing a large amount of chakra into a person; this is part of the application of that Fuinjutsu..."

Shuichi quickly understood the meaning after hearing this. Simply put, the jutsu inscribed on a living person is equivalent to a mini "Jinchuriki," and this ninja is equivalent to a "Tailed Beast." This jutsu can borrow the ninja's chakra and resonate with the caster at a short distance. Theoretically, it will never disappear until death.

"So that's how it is!" He finally understood why Minato only sensed the jutsu when he was so close to Obito during the Fourth Shinobi War, why Minato was a step too slow in supporting Kakashi at Kannabi Bridge, and why the Second Hokage died in battle instead of flying away with everyone else.

After the practitioner fills the chakra paper with chakra, let's assume the amount of chakra on it is 1010. If it is set to release 2 points per day, it can last for 5 days. At the same time, let's assume that the intensity of this signal is enough for him to perceive it from 1 li away.

If it is set to release 5 points per day, it can only last for 2 days, while the perception distance may increase to 2.5 miles.

The technique imprinted on a living person starts as a dead entity, which can also be assumed to have a chakra level of 0.10. However, it will continuously absorb a small amount of chakra, and as long as the person does not die, it can be maintained at approximately 0.110 indefinitely. It can only be perceived when the person is very close.

Therefore, the Flying Thunder God Technique is not a Ninjutsu that allows one to roam freely throughout the Shinobi World once the technique is activated.

If such an effect were truly possible, Konoha would invest countless efforts to teach a large number of ninjas the Flying Thunder God, and then inscribe the technique formula all over the Shinobi World, making it no different from a magician's teleportation array. However, in reality, applying the formula to inanimate objects would be utterly useless.

"That extremely long-distance teleportation..." Shuichi didn't rush to ask about this final bug, but instead recalled the situation in the original work.

When the distance was extremely far, the Second Hokage and Fourth Hokage could only sense the chakra of Nine-Tails and Naruto; no one else could sense it. They did not fly directly there, but instead used the Flying Thunder God to speed up their journey.

"So how did the Fourth Hokage fly back to Konoha in the end? It takes an enormous amount of chakra to sense and complete the long-distance teleportation..." Shuichi squinted at the discovery in Konoha, then suddenly had a flash of inspiration and realized, "It's the Barrier! Konoha's Barrier has been maintaining an enormous amount of chakra circulation, and the Sealing Squad has been injecting chakra into it every day."

"Once Minato becomes Hokage, he can incorporate his own techniques into the Barrier, thus turning this place into his main battlefield, where he can protect Konoha at any time."

Shuichi of the Hokage lineage, knew a lot of things. For example, there were many Barriers and seals on the Hokage's house and the Hokage Rock, which could explain Minato's various actions during the Nine-Tails' Rampage.

These thoughts flashed through Shuichi's mind but he didn't say them aloud. After Minato finished explaining the Flying Thunder God Technique to Shuichi, he gave him several talismans with spell symbols in addition to the Trident Kunai.

After Minato's instruction, it was Shuichi's turn to decide whether or not to learn the Flying Thunder God Technique, or to what extent he planned to learn it.

Because he had previously gone on a mission with Minato, it can be seen that when they intercepted the Sunagakure squad from Hazuki last year, he was unable to quickly inscribe jutsu seals during ninja battles. It wasn't until this year, through the accumulation of his Fuinjutsu skills, that he was able to apply this training to actual combat and officially earn the name Yellow Flash.

It wasn't until two years later that he was finally able to use the Rasengan to teleport again in a very short time. Even for a genius like him, it took so long to master this skill, which shows how difficult it was.

Therefore, Shuichi had to consider carefully. Copying Minato's path was not a good idea. For a long time, he could only use the Flying Thunder God to attack people at close range, which would be no different from a Minato.

If this time were spent on researching Kekkei Genkai, one's strength might be more comprehensive, with an extremely powerful Body Flicker Technique combined with a variety of large-scale Ninjutsu like a cannon, making it easy to deal with both ordinary ninjas and Tailed Beasts.
