Barrier Jutsu differed from Curse Mark Jutsu, but its differences from Sealing Jutsu were not as pronounced. Although the composition of their formulas was entirely different, they were comparatively quite similar.
There was no need to start over from scratch as he had with the curse mark.
He could also use the principles of Sealing Jutsu to understand Barrier Jutsu.
It was just that, compared to Sealing Jutsu, Barrier Jutsu was its exact opposite.
If the essence of Sealing Jutsu was to create a space and "contain" external objects within it, then Barrier Jutsu expelled external objects from the space it created.
Or rather, if Sealing Jutsu expelled objects within a space, then Barrier Jutsu expelled objects outside the space it created.
Their functions were precisely opposite.
In terms of structure, they could not be called complete opposites. But once one understood this, as well as the rules governing the formation of Barrier Jutsu seals, it was not difficult to learn or undo.
Chiba's gaze fell on the final character of these Barrier Jutsu notes, and he slowly let out a breath.
The difficulty of learning Barrier Jutsu was even lower than he had imagined.
It was not nearly as troublesome as Curse Mark Jutsu, either.
It could be said that among the three formula-based techniques—Sealing Jutsu, Curse Mark Jutsu, and Barrier Jutsu—Barrier Jutsu was the simplest.
However, while it was the simplest, it was also the hardest to bring out its power in. Or rather, its restrictions on power were the harshest.
Although Sealing Jutsu and Curse Mark Jutsu were difficult to learn, once mastered, they could basically exert their maximum power. After all, if a Sealing Jutsu or Curse Mark Jutsu succeeded—if its formula was successfully constructed—then it would essentially function at one hundred percent effectiveness, regardless of
