Propping his chin with his hand, Shinji fell into deep thought.
To make the rank of the Shinjutsu reach its peak, one could not just put effort into the intensity of the chakra, because within a certain time and space, energy had a limit, and the more physical the energy, the easier it was to be targeted and countered.
Therefore, the key point of this Shinjutsu Shinji wanted to create was not in the strength of the chakra, but in the completeness of the concept; this technique had to monopolize an entire concept, and with the help of the concept, completely transcend the shackles of the strength of any single kind of energy.
"The core is still the concept of time, but how to perfectly piece together the past, present, and future?"
Shinji murmured in a low voice.
Just like Hikari and Karin were working hard to familiarize themselves with the Kekkei Mora realm, Shinji was also working hard to familiarize himself with Kekkei Shinra.
Many of his ways of thinking still remained in the shinobi period, and the problems he considered would be shackled by many rules and regulations.
After thinking for a long time, Shinji shook his head.
He discovered that he could not imagine a Shinjutsu out of thin air; this was his limitation as a shinobi, and he had to admit this.
"In that case, I might as well create a template first, and then use this template to implant the concept of time into it!"
Thinking of this, Shinji went into action.
After advancing to Kekkei Shinra, the power of the various dojutsu he had previously mastered had undergone a qualitative leap. For example, Susanoo Tomoshibi; in addition to the number of empty eye sockets increasing, the ability of Susanoo Tomoshibi to fuse had also expanded from eyes to dojutsu.
In other words, if it were merely a simple fusion of dojutsu, he could easily accomplish it using Susanoo Tomoshibi.
After activating Susanoo Tomoshibi, Shinji closed his eyes and concentrated, first selecting his own dojutsu Goshinko.
Goshinko could pause the flow of time, representing the "present," and was the foundation for bearing matter and space; therefore, if a new dojutsu was to be fused, choosing Goshinko as the foundation was undoubtedly the most stable and appropriate!
Next, Shinji also selected the dojutsu Ryūgū-jō from that pair of Blue Rinnegan belonging to Urashiki Otsutsuki.
Ryūgū-jō could briefly trace back time, representing the "past"!
Finally, Shinji selected that Hope from the Jougan. Hope could peer into the key to breaking the deadlock from the future, representing the "future"!
Goshinko, Ryūgū-jō, and Hope—these three dojutsu, in terms of strength alone, Shinji's own Goshinko was undoubtedly the strongest, enough to crush the other two dojutsu. But if the vision was raised higher, conceptually, these three dojutsu were actually equivalent.
After taking out the three dojutsu Goshinko, Ryūgū-jō, and Hope using Susanoo Tomoshibi, Shinji did not hesitate and immediately began the fusion.
Just like fusing eyes with Susanoo Tomoshibi, while fusing the dojutsu, a dazzling light flickered in the several pairs of eye sockets of Shinji's Susanoo.
However, this time the fusion did not have the previous tug-of-war, and the fusion was completed almost in one go, fusing into a brand-new dojutsu.
Shinji thought for a moment, then placed this brand-new dojutsu into the Nine Magatama Rinnegan at his brow and named it Chōga.
And the capability of this technique was very simple: it unified the three temporal concepts of past, present, and future, allowing Shinji to easily travel into the long river of time without the help of any treasure. If the effect of the technique were used as the standard for judgment alone, this time the fusion innovation was undoubtedly very successful, and could even be said to have exceeded Shinji's expectations!
But this could not satisfy Shinji!
...
Because Chōga only barely pieced together the three concepts belonging to the time side—past, present, and future.
This kind of piecing together had loopholes; one could easily jump in and also easily escape.
What Shinji needed was to monopolize the concept of time, making the past, present, and future within Chōga become the past, present, and future of the entire world. Letting the Chōga he created become the true long river of time of the Shinobi World.
This required Shinji to go and mend it, letting his Chōga overlap with the true long river of time and completely merge into one.
The specific method was that Shinji needed to go back to the past and create some history to serve as anchors, then create some deeds in reality to serve as the present anchors, and then travel to the future to create some future to serve as the future anchors.
After slightly organizing his train of thought, Shinji activated Chōga and traveled to the past.
This time he did not just stop at a surface level but traveled to the Shinobi World hundreds of thousands of years ago in one breath; at that time, there were no concepts like shinobi or nations in the Shinobi World, humans were in the primitive tribe period, with no writing and no faith, in a wild era.
Shinji found a large tribe, created part of the writing, and then quietly left.
Next, Shinji experienced one time node after another, leaving his traces in various time nodes of the Shinobi World, while trying his best not to interfere with the direction of history to prevent the long river of time from shifting.
Such a thing was unimaginable for an ordinary person, but for Shinji, whose strength had reached Kekkei Shinra and who also mastered the past, present, and future, what was needed was only enough patience and an unswerving sense of awe.
During one travel after another, Shinji could clearly feel that the part of his Chōga belonging to the past was becoming more and more real and powerful.
"It is almost enough..."
After thinking this to himself, Shinji returned to the time node where he was.
After overlapping the "past" of Chōga with the "past" of the Shinobi World, the next step was to overlap the "present" of the two; this point was very simple, because in every present moment, Shinji was drastically affecting the Shinobi World, so as he just sat quietly in the central practice field of the Flying Fortress, the "present" of Chōga achieved a perfect unity with the "present" of the Shinobi World.
"Next is the future..."
Shinji's gaze sharpened, because he was not sure now if the Shinobi World still had a future, so he did not travel into the far future but traveled to a few months later.
The Shinobi World a few months later was filled with thunder and lightning, and the sky was dark and the earth was dim, identical to those worlds of the extinction society that were about to step into destruction.
Rumble
Watching this scene, Shinji frowned slightly.
Then he tried to continue traveling, traveling to a more distant future, but found that no matter how he activated Chōga, he had no way to travel to a more distant future.
His expression first froze, thinking the Shinobi World might have no future, so his Chōga could not carry him to continue traveling, but then he reacted, realizing the future is created; at this time node, the future of the Shinobi World might need to be created by his own hands!
