The guard conducted an extremely thorough body search according to procedure, even opening the insulation box to inspect whether the cans of exquisitely packaged caviar contained any foreign objects.
The CIA agent, disguised as a supplier, felt his heart pounding, but he maintained a humble and anxious expression of a businessman on his face.
He had undergone repeated training and psychological preparation beforehand, knowing this was the most critical juncture.
He was carrying a high-tech slow-release toxic substance, sealed within specially-made micro-capsules, cleverly embedded in the lid's layer of one of the caviar cans, undetectable unless the can was completely dismantled.
Once the can was opened and the caviar stirred, the specially-made capsule would break under pressure, and the toxin would mix evenly into the entire can of caviar, colorless and tasteless, hard to detect.
