When Chen Chen saw this, his eyes grew solemn. In the movie, David had only added one small drop into a drink to infect a human adult, who had transformed into a humanoid monster within ten hours.
It was evident that the black goo was not a bacteria or a virus, but a very stable polymer compound. Otherwise, it would not be able to withstand the damaging effects of alcohol so easily.
At this time, the Black Knight was copying David's actions in the movie. He broke off the tip of the popsicle, then inserted a syringe from one side and extracted a very small amount of liquid black goo from the popsicle.
Some of the Black Knights immediately placed a part of the black goo under the microscope for analysis and observation while others injected the fluid into a white mouse that had been prepared in advance.
Soon, Chen Chen saw that the mouse injected with black goo had begun to develop fever and convulsions.
