This barrier should be enough to defend against grave robbers like Orochimaru and Kabuto.
Watching the golden chains that formed the barrier gradually fade away, Chiba slowly let out a breath. Looking at the three corpses on the stone platforms before him, corpses he had completely restored with Yang Release and that seemed as though they might awaken at any moment, this thought crossed his mind.
Sealing Jutsu, Curse Mark Jutsu, and Barrier Jutsu—though the three techniques served entirely different purposes, they belonged to the same system. Based on Chiba's current knowledge and understanding of such techniques, they had most likely originated from the same jutsu, merely divided into three parts.
Of course, that was only a guess.
It was also a conclusion Chiba had reached after seeing the space created by the Sage of Six Paths to house the spiritual body of his past self. There was no concrete evidence.
However, that spiritual-body space had clearly used Sealing Jutsu to carve out a space, then Barrier Jutsu to create a state of isolation that shut out every factor harmful to the spiritual body of his past self. Finally, Curse Mark Jutsu had been applied to the spiritual body of his past self, stabilizing it from within and creating a temporary localized spiritual body to prevent it from being rejected and destroyed.
Although Chiba himself had ultimately become localized, his past self had not. In other words, his past self still belonged to an outside world and could easily have been judged an outsider, rejected by the entire world, or even triggered the world's destructive response.
