In this chapter, we learn that the Silver-Wing family has been using their secret technique to increase their strength, but that their leader, the patriarch of the Gray Wolves family, has not been able to help him become the leader of the thirteen families that inhabit the "black prison realm." The patriarch tells his son that the living conditions are getting worse, and that they need to find a leader to lead them out of the " abyss prison realm" . The patriarch asks his son to eat the profound marrow pills that the family gives him, but the father refuses, saying that he has no choice but to kill the patriarch.
