Yang Xiaojin just looked at Ren Xiaosu. They had attacked her because she wasn't a resident of the stronghold? What kind of nonsense was that!
Suddenly, Ren Xiaosu said, "This particular group known as the Experimentals have been growing stronger and stronger. When I was on my way to rescue you, I saw an Experimental inject a normal human being. When the gray liquid was injected into that person's body, he somehow turned into an Experimental as well."
Yang Xiaojin was hearing this for the first time. She said in shock, "So if they inject all of the stronghold's residents with that drug, wouldn't there be hundreds of thousands more Experimentals? No, wait, they're probably selective about who they inject it into."
