The first four generations of Naruto

Namikaze Minato doesn't know exactly how many ninjutsu Senju Tobirama, the great inventor of the ninja world, the Second Hokage, invented, but traces of his achievements and creative ninjutsu can be found in various organizational facilities in Konoha. , you can know how much influence this man has on Konoha...

Speaking of work-related matters, Liyin suddenly seemed like a different person, her expression brightened and she said, "Yes, Hokage-sama."

"The Ninjutsu created by Nidaime-sama is still in use today, and it closely protects the village..."

Rione's gaze became a little distant and yearning. Each generation of Hokage was deeply respected by the villagers of Konoha. This was a manifestation of the people's centripetal force.

"Yes, it is said that in the beginning, this barrier technique and the mirror monitoring at the center could only be controlled by a sentient ninja." Minato Namikaze sighed as he searched for detailed information about various departments in Konoha in his memory.

The prototype of the Three-Yuan Boundary Sealing Formation is actually the Boundary Sealing Formation.

Sanyuan refers to three representative areas that are monitored and controlled by three sensory ninjas at the same time.

After all, the scope of Konoha Village is too large. If one person were to monitor and control the entire formation, no matter who it was, it would be somewhat powerless.

But if the characteristics of the barrier technique are modified and three people monitor it together, then the work efficiency will be greatly improved.

In my memory, it was Tobirama Senju who created this technique, and it was improved by Hiruzen Sarutobi, and it became the current Three Elements Sealing Formation.

"Hokage-sama, there is something I feel the need to report to you..." Rione said seriously as she recalled the record report of the barrier team on duty today and was about to enter the underground database.

"Before the Nine-Tails incident, the barrier class had sensed unrecorded chakra aura many times at different times, and invaded and passed through the barrier formation many times."

"The Konoha Anbu and Konoha Guard members who were dispatched after hearing the news many times rushed to the scene of the incident and found nothing unusual..."

"But since the incident, this abnormal situation that appeared from time to time suddenly disappeared..."

Namikaze Minato was slightly startled and started to think.

There will definitely be no problems with the three-dimensional sealing formation.Since the intruder was detected, there must be a strange chakra aura invading Konoha.

The ANBU and the security team have checked many times, but to no avail. This is really weird.

"Can someone invade Konoha without a trace?" Namikaze Minato pondered, stopped, then looked at Rione and asked: "Captain Riine, did you find anything?"

Before the Nine-Tails incident, the barrier team did report the matter to the previous Namikaze Minato many times. However, after repeatedly checking the intruder to no avail, the original Namikaze Minato and the barrier team had to conclude that it was a three-dimensional seal. There may be something wrong with the formation. The original plan was to have the Fourth Hokage preside over the formation to inspect and reform it after the Jinchuuriki was produced.

But before all this could proceed, the new wave of Feng Shuimen was ushered in and the Nine-Tails Rebellion...

Just as she thought, Liyin nodded, no longer hesitating, and said bluntly: "Hokage-sama, the intruder who heard about the Nine-Tails incident is an Uchiha traitor ninja who can use time and space ninjutsu... ..”

"So I suspect that the strange invasion fluctuations that often occurred before were probably the work of that Uchiha traitorous ninja..."

After Rione finished speaking, she turned her gaze to Namikaze Minato, who was thinking seriously about something.

After all, this is just her guess. The Sealing Formation, the large formation covering Konoha, is not perfect. It has been continuously updated and transformed after decades, which can prove this.

Rione's words really woke up Minato Namikaze.

Before traveling through time, he had doubts about this detection barrier that could cover Konoha.In the original work, after Uchiha Itachi defected, when he sneaked into Konoha Village with his partner Inikaki Kisame, he was able to avoid detection because Itachi was once an Anbu and knew the special seal that could not touch the barrier.

Even when Pain forced his way into Konoha, he was discovered immediately.

Therefore, before the Nine-Tails Incident, the frequent invasion fluctuations were definitely caused by Obito Uchiha.

This also shows that as long as you invade Konoha, even if you use space ninjutsu, you will still be discovered.

It's just that the power of the gods is indeed powerful. Even if he is found to have passed through the barrier, the ANBU and security teams who are currently investigating arrive, and Uchiha Obito has long since escaped without a trace.

"Your guess is correct. Uchiha Obito's divine power can indeed do this." Minato Namikaze smiled helplessly. He first agreed with Rinne's words, and then said with great seriousness: "That's fine, Sanyuan Seal." The Realm Formation should really be upgraded and maintained.”

"...Hokage-sama, do you want to...reform the barrier again?!"

Liyin was a little surprised.

The third Hokage, Hiruzen Sarutobi, was able to expand the sealing formation into three elements, which was enough to show his talent for learning and memorizing.

Omniscient and omnipotent, a Ninjutsu professor can only go so far.

But Namikaze Minato said that he wanted to further transform the barrier formation, which couldn't help but surprise Rine.

If another person had said this, I am afraid that anyone would be dismissive, or even laugh at his arrogance, but if it comes from the mouth of the youngest Fourth Hokage, Namikaze Minato, it will be different...

"Okay, don't be stunned, open the data room quickly." In the deepest part of the dark underground passage, the oil lamp next to the wall shines dimly.

Compared to transforming the three-dimensional sealing formation, there was something he wanted more.

After being reminded, Liyin realized what she was doing. She hurriedly took out a bunch of keys and opened the locked iron door.

When all the locks were unlocked, facing the last iron door, Liyin quickly made several seals, and the door suddenly opened automatically.

Minato Namikaze would not be surprised that these layers of locks and insurance were protective measures for a secret place.

......

After half an hour.

After spending a lot of effort, Namikaze Minato finally found what he wanted.

It was a ninjutsu scroll stored in the data room of the barrier class headquarters. What was recorded on it was the one used by the ANBU when they built the birthplace of Kushina the other day. It was modified by the second generation, and its original form was the sealing technique of the first generation Hokage. The secret technique of sealing the Mingshen Sect.

Because this barrier secret technique scroll records not only the principles and usage of the technique, but also the creative experience written down by the Second Hokage during the transformation.

Senju Tobirama also worked hard for Konoha. Most of the recorded ninjutsu he left behind will have comments such as comments. Namikaze Minato wanted to test these left comments to further study the Myojin Gate. Sealing technique.

Last night in his conscious space, he was accidentally kicked out by Yin Jiuwei's sneak attack, which made him suddenly consider a problem.

The seal on his body is now just a simple four-image seal. There is absolutely no problem in sealing half of the Nine-Tails stably, but to suppress the Nine-Tails and then control and forcibly use its power, it needs to be strengthened. Only layers of four-image seals are enough.

Because the principle of Bagua seal is the superimposed effect of two Four Symbol seals.

If Namikaze Minato has the Four Elephants Seal, I am afraid that the Yin Kyuubi's space in the consciousness space will become smaller. There should be a high golden gate in Naruto's body that locks the Kyuubi like in the original work.

However, Namikaze Minato, who had a sudden whim, actually did not want to strengthen a four-element seal again like the original work, and use the Bagua seal to gradually control the Nine-Tails to use his power.

What he wants is to first understand the Myojin Gate sealing technique of the first Hokage, and directly suppress the power of the Nine-Tails in one step...
