After the two exchange records were placed in the same evidence room, the black sample remained active for the first time.
It did not strike the glass tube.
It simply clung to the side facing the black stone fragment, its edges rippling faintly each time the recording team turned a page.
The Sealing Squad cut off the transmission of sound, light, and chakra.
The sample could still tell exactly when the stone fragment was removed.
A connection existed between it and the black writing that did not depend on ordinary perception.
Gen did not leave the genuine exchange records where they were.
The witness page for the bamboo whistle duplicate was divided into three sections.
The black stone fragment was replaced with a stone imitation of the same shape.
The genuine evidence was entrusted separately to the Records Room of the Hokage's Direct Subordinates, the Uchiha witness room, and the soil-free medical Isolation Zone.
If any one location was destroyed, the other two could still establish what had happened during the exchange.
Only a reconstructed transcript with a deliberately incorrect time was left in the evidence room.
The error concerned "twenty-three minutes."
The recorder changed it to nineteen minutes.
If the black will later corrected or targeted that number, Konoha could confirm that it had not merely sensed the stone fragment, but had also read its contents.
Less than a quarter of an hour after the test began, the captured White Zetsu suddenly collapsed.
Three walls and independent seals separated him from the black sample; he should not have been affected.
Yet a black shadow rose beneath his feet, like a shadow stretched by lamplight, and traveled along the wall, passing straight through the first partition.
The alarm did not sound immediately.
The seals targeted physical matter, chakra, and space
