The black market merchant smiled and said, "No rush. Come with me to draw some blood and do a checkup. Come over every few days to see if there's a successful match. If there's none, wouldn't it be rather awkward to meet a volunteer donor now? Furthermore, it's easy to leak my sources."
"Alright." Han Wanghuo didn't think there was a problem. He wasn't too worried that his Subhuman identity would be exposed because, in a sense, the black market merchants, unlicensed doctors, and arms dealers on Antanna Street treated everyone equally.
In short, it didn't matter if one was a normal human or a mutated Subhuman. They were welcomed if they had money, supplies, and strength. If they didn't have any of those, they were unwelcome. As for those who had money and resources but lacked strength, they could only work in cahoots with each other.
