The two Founding Societies: only one of which adhered to the original tradition where they continued to find ways to serve humans in the dark. They used dead bodies in experiments related to the insect warriors, searching through files from prisons to find death row inmates who had deliberately committed evil deeds, and not those who were forced by the society into what they did. Then, they used these bodies for human experiments.
Zhang Hao's Founding Society did not care about this problem at all. They selected people who were suitable for becoming insect warriors from society, and members who were suitable for their various experiments. They then transformed all these people into insect warriors in human experiments.
