"It's been a pleasure working with you, Doctor Hansen."
Fury generously handed over a check while arranging for his men to prepare the testing reagents. One advantage of the S.H.I.E.L.D. under Fury's command was that it never delayed payment to scientists.
Maya Hansen had proposed a simple method of detecting Skrulls based on the human body's rejection response. It involved processing Skrull blood through a series of steps to isolate serum free of red blood cells and enzymes. Then, all they had to do was give suspected individuals a skin test similar to a penicillin test.
Skrulls possessed stronger physiques than humans, and their cells were highly active. The immune cells in their blood produced intense rejection responses when exposed to foreign cells.
Simply put, if a tiny amount of Skrull serum was injected beneath a human's skin, a red rash would form at the injection site, and their body temperature would rise.
But if the person being injected was a Skrull, none of that would happen, because they were of the same kind.
That was roughly what it meant, anyway. Fury couldn't really understand it.
Black Egg was an old relic himself. He had lived from World War II to the present day, and though he had done his best to learn the technologies and espionage techniques of the Internet age, biology was not something a director like him had any real need to study.
All he needed to know was that there was a way to identify Skrulls hidden among the public, then sign the check.
"I'm pleased as well." The Female Doctor smiled as she accepted the check and happily slipped it into her pocket, showing none of the usual reluctance technical staff had toward discussing money. "I made a hundred thousand US Dollars in just a
