Gen dismantled the Ten-Tails Husk into nine vacancies that could not complement one another

As Black Zetsu's remnant core approached the sixth interface, Gen did not immediately impose containment.

Containment would tell him that the Living World had already discovered his location.

He could shift into any of the other eight interfaces.

The Recorder from the Land of Rivers continued marking them in their original order.

Konan divided the nine layers of Paper Seals into nine groups that never touched one another.

Each group corresponded to only one vacancy.

No two groups exchanged chakra.

The nine groups of Paper Seals did not even use the same timing formula.

The first group relied on a dripping-water scale.

The second recorded vibrations in the rock strata.

The third had two ordinary Recorders take turns calling out the time.

If all of them used a synchronized chakra clock, Black Zetsu would only need to control a single rhythm to make all nine locations misjudge the situation at the same instant.

Different methods would produce slight timing discrepancies.

That made the dismantling slower.

But it also meant the nine interfaces no longer shared the same start and end signals.

The Five Nations could only see the group each was assisting.

Nagato, too, only confirmed the corresponding outline before each severance; he was not given the complete arrangement of the nine groups of seals.

Gen likewise kept no overall diagram.

The Land of Rivers only knew which group had finished, not which tailed beast had supplied its refusal format.

It was meant to ensure that anyone who came to power later would lack the conditions needed to restore the whole in a single attempt.

The first interface was cut off from observation as part of the whole.

The Demonic Statue's outline in Nagato's left eye lost a
