[Good day Master Zultra.] Once Blake stepped out of the corridor and into the center region, the mechanical golems scanned him.

Without slowing down, Blake walked towards the unsuspecting golem on the right side of the room.

When he was only a meter away, he threw the book back to the entrance of the corridor, causing the golems to scan the journal in mid-air.

When the journal was about to hit the floor, a black ethereal tendril shot out of the corridor, catching it and handing it over to Castiel as he stepped out of the corridor.

[Scanning: Master Zultra.] Immediately the journal came in contact with Castiel, his ID changed to that of Zultra, causing the golems to turn back to Blake.

Boom!
