"Chief Charles, you've already been a seventh-grade Grandmaster for many years. Could it be that you can't even kill that crocodile demon at the peak of the sixth-grade?"
In the VIP room, Dean Carroll asked faintly.
Charles smiled bitterly. "That beast is too cunning. It only moves around the artificial lake. Once I find it, it will hide in the lake. Once inside the lake, there's nothing I can do about it... Besides, half a month ago, I secretly went to the East River Park and discovered that the cosmic energy was gathering there. The crocodile demon seems to be showing signs of a breakthrough. In a few days, it might be able to step into the seventh grade. When that time comes, it will be even harder to kill it!"
Human warriors of the seventh grade could be called "Martial Grandmasters".
Among Demon Beasts, although there was no "Grandmaster" rank, the strength of a seventh-grade demon beast was not much weaker than a human Grandmaster.
