Hokage Residence

Konoha

At night, the lights were on on the third floor of the Hokage Residence Hokage Building. Naraku a futon in the living room on the third floor, holding Ninjutsu scroll in his hands.

A large Scroll of Sealing Scroll of Sealing placed in front of the prayer mat, and several small scrolls were placed beside it.

The Hokage Residence stores a vast amount of Konoha's data and secrets. Among these data are many dangerous Konoha Style Ninjutsu scrolls, including the Scroll of Scroll of Sealing, which involve advanced Ninjutsu and forbidden techniques. Leaking them would cause incalculable harm, and they have always been guarded by the Hokage.

The Scroll of Sealing contains many Konoha Style Ninjutsu and forbidden techniques, but it is mainly a catalog of Ninjutsu. Some powerful and unique Ninjutsu are recorded on separate scrolls.

Becoming the Hokage of Konoha allows one to learn all of Konoha's Ninjutsu. Hokage with strong learning abilities, such as the Third Hokage, are known as the "Professor of Ninjutsu," proficient in all five elements, and have mastered all of Konoha Style Ninjutsu.

He doesn't usually use many Ninjutsu, but that doesn't mean he can't. Adapting to the situation is the Third Hokage's forte; no matter what element an enemy is good at, they will be countered by the Third Hokage's element.

The training and use of ninja tools and Summoning Beast were the Third Hokage's greatest strengths. His three students, each with their own unique Summoning Beast, earned the title of the Legendary Sannin, which was undoubtedly related to his teachings.

"Flying Thunder God Technique, I see. It's a truly complex Space-Time Ninjutsu. No wonder he's the Second Hokage."

Naraku studied the Scroll of Sealing for a long time. The Ninjutsu catalog in the Scroll of Sealing covers Ninjutsu, Taijutsu, Genjutsu, swordsmanship, as well as Fuinjutsu, Juinjutsu, and Barrier Ninjutsu.

The scope covers space-time techniques, sensory techniques, the five Chakra natures, Wood Release techniques, the Eight Inner Gates and other secret techniques, and soul-related secret arts. There are even many that are just ideas and concepts, not Ninjutsu.

Naraku was engrossed in reading, and as he flipped through the pages, he found descriptions of forbidden techniques and the locations of Ninjutsu scrolls. Finally, Naraku found Ninjutsu that interested him.

"Does it require a special constitution? A constitution that excels in space-time manipulation, perhaps, using Chakra to mark nodes, then sensing those nodes to traverse..."

On the small scroll in Naraku's hand was written an "S," which was the Flying Thunder God Technique. Naraku carefully studied the Flying Thunder God Technique for about half an hour, and after finishing the scroll, he summarized the key points of the Flying Thunder God Technique.

Thinking about it, Summoning Technique, such as summoning ninja tools, can actually be considered a space-time type of ninjutsu, but this type of Ninjutsu doesn't require high skill from the user.

The Flying Thunder God Technique has only been performed by two people in the history of Konoha: Second Hokage Tobirama Senju who developed it, and Namikaze Minato, who successfully mastered it.

Naraku had never seen Senju Tobirama's Flying Thunder God Technique, but he knew how powerful Namikaze Minato 'Naraku Flying Thunder God Technique was.

"I possess a spatial ability, so my spatial talent should be quite good. In terms of perception, I'm no less than Senju Tobirama or Namikaze Minato. Let's try marking the Chakra nodes."

Naraku acted on his impulse, his right palm pulsating as an ancient longsword appeared. Naraku used Chakra to imprint a mark on the hilt.

"It's done!"

Following the requirements of the Flying Thunder God Technique, Naraku successfully engraved the Flying Thunder God mark on the hilt of his longsword. The mark of the second generation was a pattern, while the mark of Namikaze Minato was the words "Sword of Shinobi and Love". Naraku's mark followed Namikaze Minato's example, also engraving words on the hilt and marking "Peace Under Heaven".

"Let's not go too far, we can try the interview here."

Naraku his right hand, revealing the hilt of a longsword. Naraku the sword and tossed it into the center of the living room.

Bang!

The longsword landed with a thud on the floor about ten meters away. As the residence of the Hokage Residence, and especially since it contained many confidential documents and Ninjutsu scrolls, Naraku couldn't easily damage the floor facilities.

Naraku sensed the markings on the hilt of the longsword as his Chakra fluctuated. He Hand Seals, and his Chakra moved according to the Flying Thunder God technique.

Bang!

Naraku appeared on the sword with a grasping gesture, his right hand gripping the hilt, Naraku upright in front of him.

Bang!

Naraku sat back down on the futon, his right hand gripping the longsword. As Naraku threw the sword, he also left the Flying Thunder God mark on the futon.

The first time Naraku, it was quite standard, even Hand Seals for assistance. After experiencing it, the second time he used hand Hand Seals with one hand and succeeded just as well.

Naraku closed his eyes tightly, carefully sensing the feeling of Flying Thunder God.

"I see... My perception range is a radius of 100 kilometers, which means I can travel freely within a 200-kilometer radius. I just wonder if the distance will affect the consumption of Chakra."

Naraku successfully mastered the S-rank Space-Time Ninjutsu in one Naraku. He possessed all the necessary hardware and software to train the Flying Thunder God Technique, which was exactly what Naraku expected.

Naraku's right palm faced his face, and two rhombus-shaped marks appeared on his palm, emitting a suction force. As Naraku's palm moved, his figure disappeared on the spot as if erased by an eraser.

Within the alternate dimension inside Naraku's body, the soul of the Kaguya Clan man he had previously devoured had disappeared, completely absorbed by Naraku and becoming nourishment for Naraku's soul to recover and grow stronger.

The soul cocoon of the Uzumaki Akayuki faded considerably from its original deep blue color. When the color turned completely white, it meant that the soul had been completely absorbed and dissipated.

The alternate dimension within Naraku's body is entirely under Naraku control. When this alternate dimension was first created, it was 400 meters in diameter. After many years of development, it has now reached a radius of nearly one kilometer.

A radius of one kilometer may seem large, but it is actually smaller than the Uchiha Clan Compound. It was Naraku's years of Chakra expansion that such progress was achieved.

Naraku sat cross-legged in the mansion inside his body, his hands forming a mudra.

"This world is still imperfect; it barely has a concept of time, and spatial expansion is even slower. The spatial understanding of the Flying Thunder God Technique is indeed of great help in spatial expansion."

Naraku's Chakra connects to this world, and through the transmission of Chakra, the area of this alternate dimension within his body is expanded.

Naraku originally expanded his internal space by forcibly pouring in Chakra to enlarge the area. Now, having mastered the Flying Thunder God Technique, his understanding of space has deepened. Expanding space is no longer a violent, forced infusion, but rather a matter of technique.

Expanding the internal space has become an effortless task. Before, it was like a reckless brute who only knew how to swing a hammer. Now, it's like an architect who, after planning, gently taps a few times, achieving twice the result with half the effort.

Naraku's lower abdomen, specifically his dantian, was filled with liquid Chakra. Due to Naraku's Chakra consumption, the 600-meter diameter that had originally taken six or seven years to expand had been reduced.

In just a short while, the space inside his body expanded again, to 1,100 meters, then 1,200 meters.

Naraku exhausted most of his Chakra, expanding his alternate dimension to a distance of ten kilometers, a tenfold increase, a completely different concept from his previous arduous efforts.

"Phew! Using up this Chakra makes me feel much better."

Naraku exhaled, and two rhombus-shaped marks appeared in his right palm. With his palm facing him, he emitted a suction force. Naraku himself down from head to toe, disappearing completely and returning to the Hokage Residence.

"I benefited greatly!"

Naraku his forehead, but he had never felt so refreshed as he did today.

Naraku wiped his forehead with his sleeve and continued flipping through the Scroll of Sealing. As he looked down, the next Ninjutsu was called Impure World Reincarnation.
