Although the Great Grandmaster and the Grandmaster were only one realm apart, they had essential differences.
When he had heard about the Great Grandmaster years ago, he had wondered if there were several realms in between?
Unfortunately, reality had told him that after becoming a Grandmaster, the next step was the Great Grandmaster, and no other realms existed.

However, the Valley Master did share with them the destructive power of a Great Grandmaster level.
