All Great Emperors were watching closely.
They saw the huge black steel ball roll over everything like breaking pieces of deadwood. It even crushed the holy kingdom into pieces.
The Great Emperors' gazes became terrified.
It was really an astonishing sight.
One should know how spacious a holy kingdom was and how many the cultivators were there.
Even those Great Emperors, although they had absolute power and they could definitely destroy a holy kingdom, their destruction was limited to taking out the higher-ups only. As for killing all cultivators in the territories of the holy kingdom, although they would be able to do it, it would require a long time.
After all, even if a Great Emperor were to destroy the world one by one, a holy kingdom was made up of thousands of worlds. It would take long enough to be entirely wiped out.
