In the sterile environment of the laboratory, the sound of scalpels and medical instruments had ceased, signaling the end of the dissections. The researchers stood back from the operating tables where the remnants of their meticulous work lay. One by one, they began to evaluate the quality of the zombie cores they had extracted.
A senior researcher peered through his glasses at the line of specimens now laid out on the pristine surface. "Any variations in quality?" he inquired, his voice steady, betraying neither disappointment nor hope.
A junior scientist, clutching a digital tablet to his chest, scrolled through the data. "It's consistent with the previous extractions, sir. No significant deviations," he reported, his tone matching the clinical atmosphere of the lab.
