"One more thing, I want to inject everyone in the farm with the drug to become an Evolver. There have been more and more people getting poisoned recently. Even the best people would not be able to hold on after such a long time. I've received news that many colonies are driving people out. If someone is unconscious, they will throw them out immediately. Even if you have a cold, they won't let you live."

"How many serums do you need?"
