He reclined lazily on the sofa, lifted his eyelids, and said with a smile that was not a smile, "Yet I heard everything loud and clear from outside. What, could it be that my ears are failing me?"
Cold sweat incessantly broke out on the principal's forehead, utterly unable to fathom how he had managed to provoke the Iron-blooded Colonel.
