"Grand Thousand Sword Formation"?
Lu Changsheng obtained a Heaven Rank Sword Array cultivation technique, which, judging by the name, seems to be a supreme sword formation capable of manipulating a thousand Flying Swords.
Controlling thirty-six Flying Swords in the Tiangang Sword Formation was already extremely difficult.
Controlling a thousand Flying Swords would be far more challenging than handling just thirty-six.
As Lu Changsheng browsed through "Grand Thousand Sword Formation," he learned that this sword array could control up to a thousand Flying Swords at most, but the core of the formation consisted of either thirty-six or seventy-two Flying Swords. The peripheral thousand Flying Swords, driven by the sword formation's aura, could seek out enemies on their own.
"In other words, the surplus Flying Swords can also be integrated into the Grand Thousand Sword Formation."
