One is centered on humans, the other on symbols. The distinction is obvious. However, array symbols have their unique advantages; once activated, cultivators only need to assume their positions to maximize power, and the range and cohesion are much better than array disks.
All three departments of martial arts have prepared array symbols, but these are usually reserved for the ultimate showdown. It's not yet time to use them.
The Eastern faction has its preparations. The only Nine-Melody Chain Array symbol is in Hai Tang's storage ring, but they can't use it lightly because if they do, the opponents will respond with their array symbols, leading to a quicker defeat.
In any case, it is considered a trump card for the Eastern faction.
Now, Lu Ye has taken out the array disk, letting everyone experience the As-Close-As-Siblings mystique, undoubtedly providing more strategic choices for the Eastern faction.
