"If we stimulate a light opposite to this phenomenon based on it, what would happen?"
Ino's azure eyes sparkled as if her pupils contained the stars of the entire sky... She immediately thought of an effect completely opposite to 'blinding titanium dog eyes'—turning white light into black light, covering an area instantly. Darkness would swallow a large space in a flash; no matter how powerful someone's eyes were, they would be blinded instantly in such a situation.
But whether it was white or black, the effect produced by this Ninjutsu was consistent; in fact, they were simply two sides of the same Ninjutsu.
Inoichi Yamanaka began to regret skipping classes so often with that guy Shikaku back in school... 'Opposite'? Heaven knows what would happen with 'opposite'—it wouldn't be 'black light', would it?
He asked tentatively.
"Black light?"
... "Yes, black light! And this light is formed by Chakra..." Ino waved her small hands, looking excited.
Inoichi Yamanaka and Mrs. Yamanaka had no idea what Ino was so excited about—
Whether it was white light or black light, it was both a color and a type of Chakra. One could say that this simple two-seal Ninjutsu had been a 'natural counter' to the Sharingan and Byakugan since its inception—the Sharingan, with its superb dynamic vision, would be blinded, and the Byakugan, which could see Chakra pathways and Chakra itself, would also be blinded.
And for ordinary Ninja... this Ninjutsu was definitely full of malice. Losing one's vision was simply fatal!
"But how could there be black light, and..."
"Of course there is, as long as you vibrate your meridians in the opposite direction..."
Inoichi Yamanaka... forget about this life, even if there were a past life, across two lifetimes combined, he wouldn't know how to vibrate meridians in reverse.
Inoichi Yamanaka gave a dry cough and stiffly changed the subject. "Ino, watch closely. This is the Substitution Jutsu—once you learn the Substitution Jutsu, you will have finished learning the most basic Three Basic Jutsu of a Ninja. Watch carefully: Ram—Boar—Ox—Dog—Tiger..." After finishing the hand seals one by one, the Substitution Jutsu was successfully performed.
A teacup replaced Inoichi Yamanaka, appearing where he had been sitting, while Inoichi Yamanaka moved behind the table.
Ino watched the hand seals once and internally broke the Substitution Jutsu down into five steps: 'Chakra diffusion on the body surface', 'Chakra emission', 'Chakra positioning', 'Establishing a stable positional link', and 'Expelling the Chakra'.
Using Inoichi Yamanaka's Substitution Jutsu just now as a concrete analysis: through the Ram seal, Inoichi first let his Chakra overflow from his body surface, then through the Boar seal, he diffused the Chakra—different from the diffusion of the Snake seal, the 'diffusion' of the Boar seal was actually a form of 'perception', sensing a specific object or, if there was no object, just a coordinate. Once a stable connection was established between the two, he used the method of repelling Chakra... Whoosh!
Through the characteristics of Chakra, a miraculous displacement occurred. As for whether this was a'Space Ninjutsu'—it probably was!
Reason one: High-speed movement inevitably produces strong wind pressure, but the high-speed movement of the Substitution Jutsu has no wind, so it can only be a type of space-to-space replacement.
Reason two: The Substitution Jutsu requires not just hand seals, but a full five seals... If it were simple high-speed movement, why would seals be necessary? To show off? To look cool? No matter how you look at it, that doesn't make sense.
Reason three: Ino's fundamental understanding of the twelve seals.
'Boar' vibrates the Hand Shaoyang Sanjiao Meridian, which connects all vessels and governs all Qi, making the body's meridians flow smoothly and quieting the mind—this is a prerequisite and method for 'perceiving' a specific object or coordinate.
'Ox' vibrates the Foot Jueyin Liver Meridian, which can make one's spirit vigorous and excited.
'Dog' vibrates the Hand Jueyin Pericardium Meridian, which can expel external evils... It is exactly these miraculous vibrations of different meridians that produce Chakra with different functions. When these Chakras are combined in a certain order, they generate different effects—of course, this combination is still crude—but it is already miraculous enough. So miraculous that Ino had some new ideas regarding the family's Secret Technique based on the hand seals of the Substitution Jutsu.
If the Boar seal is the starting seal, followed by the Dog seal to build a stable and unique connection, and then the Rooster seal to vibrate the Foot Shaoyin Kidney Meridian, it would produce hidden functions and convert them into Chakra.
Then use the Ox seal to make the spirit excited, followed by the Horse seal to make the mind clear, resulting in a state that is both clear and excited.
Then finally the Ram seal—overflowing the Chakra through that unique channel.
"Boar—Dog—Rooster—Ox—Horse—Ram... Dad, remember this sequence of seals..."
Ino was still young and hadn't learned the family's Secret Techniques yet, so this kind of experimentation could only be left to Inoichi Yamanaka.
During the 'creation' phase of a Ninjutsu, there is actually no danger—with just those twelve hand seals, the worst consequence is simply failure. What's truly dangerous is acting recklessly; when a Ninjutsu is unfinished and its power unknown, experimenting with its power at that time could very likely result in being harmed by one's own Jutsu.
Speaking of which, one must mention 'Forbidden Jutsu'. The reason Forbidden Jutsu are dangerous is that once they reach the completion stage, they can be unleashed but not retracted—
Similarly, it is the result that is dangerous, not the process.
Inoichi Yamanaka asked, "What is this?"
"An auxiliary type of thing..."
After Ino finished speaking, she asked Inoichi Yamanaka and Mrs. Yamanaka to wait a moment. She ran back to her room, brought out a scroll, unrolled it to reveal various data she had recorded, and began to explain to them exactly what this six-seal 'auxiliary' was—explaining it seal by seal in detail.
Inoichi Yamanaka and Mrs. Yamanaka grew more serious as they listened. They found it hard to believe that this was something Ino had come up with in just a short while.
If this were true, its significance to the Yamanaka Clan would be immense. Various flaws in their original Secret Techniques could be eliminated by such an auxiliary method.
For example, after performing 'Mind Body Switch', one's own body loses control and becomes incredibly vulnerable; or if the opponent's spirit is strong, rushing in headlong could result in being injured by a backlash; or how it can only move in a straight line, with those able to make it turn being as rare as phoenix feathers; for example... Inoichi Yamanaka took a deep breath. While his mouth praised Ino, "Oh, this is truly amazing," his heart was roaring—
"Hold it! We must hold it! This Clan Meeting cannot be delayed for a single moment! We'll hold it tomorrow night!"
