To put it bluntly, even though this was a title above Grandmaster, the difference between them was not in their array Dao abilities, but in their ability to create and inscribe array discs!
All diamond-rank grandmasters would naturally study and inscribe array disks before becoming Mystic cultivators.
For example, Vice-President Zhu was a bronze-level array master, but his array skills couldn't be compared to Lin Yi 's.
Even Shi tiancai should be stronger than Vice-President Zhu, so becoming a Xuan master was not difficult, but it was not easy either!
Putting aside the ability to inscribe array disks, the quota for the Xuan master examination was very rare. Due to the scarcity of the quota, it was extremely precious.
Of course, if one wanted to take part in the assessment, one had to be a diamond-level Grandmaster first. The threshold was so high that it blocked most people.
