Ōnoki: "Am I mistaken? He seems to be trying to perform Sealless Jutsu!"
Fourth Raikage: "The most important thing is… this Uchiha Sasuke is only eight years old!"
Eight years old!
For an average ninja, being able to master basic ninjutsu at that age would already be impressive.
And this Sasuke Uchiha from the parallel world… he's even trying to develop a Sealless Jutsu!
Terumi Mei: "You make it sound like he can just do it if he wants to! How could Sealless Ninjutsu be that easy?"
Hatake Kakashi: "It would be great if we could simplify things — even just reducing the number of seals, let alone removing them entirely…"
Senju Tobirama: "If one's chakra control is strong enough, it is indeed possible to simplify the seals. Take the Water Dragon Bullet Technique, for example — if I perform it, I only need four seals."
Terumi Mei: "I can only simplify it to six."
Momochi Zabuza: "…"
He still needs to use the original forty-four seals.
Senju Hashirama: "What's so strange about that? I usually don't need hand seals at all."
Senju Tobirama: "Brother, shut up!"
Senju Hashirama: "…"
Senju Tobirama: "Don't assume others can do what you can, brother!"
A gold-framed screen.
[After confirming the direction and method of his next training, Sasuke began to make a practice plan.]
[With his body's current development, Sasuke can now create three Shadow Clones.]
[According to his plan, the original body focuses on chakra refinement and physical training.]
[The three Shadow Clones have separate tasks: one studies supplementary materials to expand his knowledge, one practices chakra control, and the last focuses on chakra nature transformation.]
[Sasuke tested his chakra and discovered it possesses two attributes — fire and lightning.]
[The lightning attribute is even slightly stronger than the fire attribute.]
[Therefore, for his nature transformation training, Sasuke chose Lightning Style.]
[As for his attempt at Sealless Ninjutsu, he selected the technique he knew best — the Great Fireball Technique.]
[Following the method described in The Summary of Ninjutsu Principles, he controlled the flow of chakra through his meridians, gradually reducing the number of hand seals until none remained.]
[One month later.]
["Fire Style: Great Fireball Technique!"]
[A ball of fire burst forth successfully.]
[However, what differed from before was that this time, Sasuke hadn't used a single hand seal.]
["…It seems… it's not particularly difficult."]
[Sasuke looked puzzled.]
[Had he really completed his first Sealless Ninjutsu already?]
There was silence in the chat room.
After a while—
Jiraiya: "There's a gap in the middle… why did he suddenly master the Great Fireball Jutsu without hand seals?"
Hatake Kakashi: "Is Sealless Jutsu really that simple?"
He had copied thousands of ninjutsu, but the only one he knew that required no seals was the Rasengan.
Orochimaru: "It seems this Sasuke's level of genius is beyond even my expectations… hehe."
Senju Tobirama: "This brat is a bit abnormal…"
Senju Hashirama: "Isn't that normal?"
Senju Tobirama: "Just as abnormal as you, brother!"
Underworld — Pure Land.
The Sage of Six Paths, Ōtsutsuki Hagoromo, was also watching the comparison broadcast.
"Uchiha Sasuke… he must be the Indra reincarnation of this generation,"thought Hagoromo.
This Sasuke from the parallel world reminded him of his eldest son, Indra.
The very first ninjutsu ever created didn't require any hand seals at all.It was Indra who later developed the hand seal system to simplify the process and make ninjutsu easier for others to use.
The talent of this parallel-world Sasuke in Sealless Jutsu made Hagoromo see Indra's shadow in him once again…
[After completing the Sealless Great Fireball Technique, Sasuke began experimenting with other Sealless Jutsu.]
[Thanks to his previous experience and his improved chakra control, his attempts became more and more successful.]
[He was also continuing his Chakra Nature Transformation training, though progress there was slower.]
[Although Sasuke could feel his improvement, it would still take time before he could fully master the Lightning Style Nature Transformation.]
[One day—]
[Sasuke was reading in the Ninja Academy library.]
[A book with an orange cover caught his eye.]
["Make-Out Paradise? What's this?"]
[Sasuke frowned, puzzled.]
[On the cover were silhouettes of a man chasing after a woman.]
[He opened it and flipped through a few pages.]
[Snap!]
[He shut the book immediately.]
[A faint blush crept onto Sasuke's face.]
["No… I can't look! This is one of the Three Ninja Taboos!"]
[Despite telling himself that, his hand moved on its own—and he opened the book again.]
['Just one more look… just to satisfy my curiosity. I won't get addicted…']
[…Half a day passed.]
Jiraiya: "…"
Hatake Kakashi: "Congratulations, Sasuke — you've opened the door to a new world!"
Uchiha Mikoto: "How could such a book even exist in the Ninja Academy library?!"
Uzumaki Kushina: "As expected… you really do have to be careful when raising kids, Jiraiya…"
Uchiha Sasuke: "…"
Was this kind of thing really that interesting?
He saw Kakashi-sensei reading books like that every day, but he himself had never been interested.
Should he… buy a copy and check it out?
Sasuke quickly shook his head, snapping out of it.
What was he even thinking? Revenge comes first!
["Sasuke, did you see a copy of… you!?"]
[Iruka suddenly appeared and froze when he saw the book in Sasuke's hands.]
[Sasuke's mind blanked for a second, but he quickly regained his composure.]
["Iruka-sensei, is this your book? I didn't see a name written on it."]
[As he spoke, he handed the book back to Iruka.]
[His expression remained perfectly calm—]
[As if he had simply found the book by coincidence.]
