Building 4 was used to imprison high-IQ criminals. Their perverseness was proportional to the meticulousness of their plans.
Building No. 5 took in all criminals. It was an equal treatment for poor prisoners who had nowhere to go.
Building 6 specialized in taking in medical staff. People with medical foundation and medical talent lived here. After all, no normal doctor was willing to be on such an isolated island. However, if anything happened to the prisoners here, it would definitely be too late to ask for medical treatment from the outside world. Therefore, there was Building 6. In order to make it easier to visit, the distance between Building 6 and all the other buildings was the same.
Building 7 was closed to talented people in a certain field.
Building 8 was filled with gamblers.
