Caroline immediately ordered Denton to get his mutant rats out of there and isolate the one that had made contact with the infected. With Nelson's guidance, Tyler and Caroline managed to separate out the mutant rat that had caught the virus. Only then did Denton realize what was happening. He hurriedly commanded his mutant rats to keep their distance from the area. But he didn't notice that Pinky, the rat he always held in his arms, had just run out and come back to him. There was already a bloody streak on Pinky's ear. He kept scratching at it with his back paw, clearly uncomfortable. A few moments later, Denton started feeling odd himself, especially in the hand that had been holding Pinky. He scratched it hard twice and immediately saw bits of flesh and blood under his fingernails. Looking down at Pinky in his arms, he saw a patch of skin and fur that Pinky had scratched off, lying right in Denton's hand. Denton instantly realized he was infected. With an infected mutant rat, Nelson finally had an experimental subject. The group decided to head back to the lab right away so Nelson could work on stopping the plague. But Denton suddenly jumped back nearly 30 feet, tears brimming in his eyes as he looked at Caroline and the others. "Tyler, Pinky and I are both infected." As he said it, Caroline saw a bloody streak climbing up Denton's neck. That was the earliest sign of infection. Denton was about to scratch at it when Tyler stopped him. "Don't scratch. Hold on!" Denton's face twisted in agony, looking ready to cry. "Tyler, it itches so much. I can't stand it." This was just the first symptom. The infected would itch. The more they scratched, the more their flesh would rot and bleed. Those sores would become breeding grounds for the virus, which would keep spreading. The virus would slowly drain away a person's strength until they were completely rotted, lost all their body fat, and finally died. Suddenly, Denton saw something tossed toward him.He instinctively caught it—it was a back scratcher. It was an Elephant Brand back scratcher from Caroline's storage space. According to the description provided by the storage space itself, this was a special item. No matter how bad the itch, two scratches would instantly stop it. Caroline had never thought it would actually come in handy. "Just scratch twice." Caroline ordered calmly. Denton obediently scratched where it itched twice and instantly felt relief. Grinning widely, he scratched Pinky twice as well, and she immediately calmed down. "Caroline, this back scratcher is amazing!" Denton beamed like a kid, examining the scratcher in his hands as if it were some kind of treasure. Without wasting time, Caroline quickly tossed Denton a set of protective gear and told him to put it on to avoid spreading the virus. Watching Denton's reaction, Caroline immediately understood why this plague hadn't caused a huge disaster in her last life—and why neither she nor Mr. Crow had ever heard of it. This plague was just too extreme. At this rate, in two days, everyone could be dead. But what Caroline didn't know was that by now, many people in the shelter were already infected. In the lab, Summer was desperately fighting off the pain and itch, working on her experiments with all her remaining strength. But her strength was fading fast, and her vision was starting to blur. Outside the door, she could hear the people in the shelter crying out in pain, which only made her more desperate. Francis had caught the plague, too. He was scratching at his neck, sores already breaking out on his face. "What's going on? How did this plague suddenly get so bad? How did those people even get into the shelter?" Francis wasn't stupid—he immediately realized something was wrong. The shelter had been targeted.He rushed to send a radio message to Nathaniel, only to find he couldn't. The signal had been blocked. Meanwhile, up on the roof of Building A on the 66th floor, the men who had been on the rooftops of other buildings were now standing confidently, radio jamming equipment in their hands. "In two days, we'll go in and take everything," one man said. Meanwhile, Caroline and the others made it to the 65th floor. They drew blood from Denton, Pinky, and the infected rat. Nelson dove right into his experiments. As for Caroline, she was planning to head home to check on Raven and Jet.
