In a novel about beast souls, the male protagonist first stabbed a woman's butt and later obtained a black stone. Could a stone evolve into a beast soul?

My answer may not be the answer you want. According to your description, the plot of the male protagonist obtaining the black stone and evolving the beast soul doesn't seem to be very common, and I haven't found a similar description in the common novel plot. However, if this is a real novel plot, then I can provide some possible explanations: - The black stone might be a mysterious substance that could evolve a beast soul. The male protagonist might need to find other similar stones to further evolve his beast soul. - The male protagonist's action of poking a woman's butt may cause him to lose his beast soul or receive some kind of punishment. Therefore, he needs to find other ways to obtain or strengthen his beast soul. - The evolution of a beast soul may require specific conditions and processes. For example, the male protagonist must display his powerful beast soul ability in a specific environment or he must obtain the support of other powerful beast souls. I hope these explanations can provide you with some enlightenment.
