In the end, however, the prisoners became the subjects of Grey's experiment. Most of them were cultivators, although the majority were ordinary mortals who possessed little to no cultivation.
Despite being considerably weaker and occupying a clear disadvantage in a world dominated by cultivators, humans would always find ways to cheat, scheme, and kill, even when they lacked the strength to confront their opponents directly. Their ingenuity in finding underhanded methods of achieving their objectives was something Grey found rather interesting.
Fortunately, everyone Grey had killed had already been sentenced to death. Their executions were merely a matter of time, and their sudden disappearance would hardly attract any attention.
Even if someone eventually noticed their absence, there would be little reason to investigate too deeply. With that consideration in mind, Grey decided to put their bodies to use as vessels for cultivating and nurturing his next batch of poison.
