The twelve pauses did not form a complete set of coordinates.
Obito had split the path into three parts.
The first was the sequence of space folding within the Kamui Layer.
The second was the chakra direction corresponding to the Demonic Statue of the Outer Path's fourth authorization.
The final part was the original opening and closing sequence of the Twelve Rings on the Lunar Surface.
None of the three could open the passage on its own.
Kakashi's left eye received only the first part.
Each time a stabbing pain arose in the outer layer of the seal, the recorder marked a dot on a blank sheet of paper.
Kakashi did not actively use his eye power.
Nor did he try to search for Obito in the direction of the pain.
Once Kamui opened from the reality side, both Kaguya and Black Zetsu might descend through the shared space in reverse.
His duty was only to preserve the signals that had already reached the outer layer of his left eye.
The medical ninja could also halt reception at any time based on the strain on his eye.
The second part reached the Land of Rain.
The Demonic Statue of the Outer Path's Aggregation Bus had already broken, but its fourth authorization had still left a residual opening deep within its spine.
Konan used nine layers of Paper Seals to record each fluctuation separately.
Nagato did not pursue the signals into Kamui with his Rinnegan.
He only confirmed whether the fluctuations aligned with the direction of the residual opening.
Eleven of the twelve matched.
The last did not fall on the Demonic Statue.
It passed through the Demonic Statue's old interface and pointed toward the inside of the Lunar Surface Sealing.
The third part was preserved by the Land of Rivers.
