Earth-shattering

"Of course, if the flying swords used are of the same build, size, weight and sharpness et cetera, it would be even easier to set up a formation."

Pausing for a moment, Xuan Yi chuckled. "But that's not too realistic unless the flying swords are created by the same Weapon Refinement Master who had specially created them as a set."

"A set of flying swords?" Su Zimo's eyes twinkled meaningfully.

"You're a disciple of Weapon Peak. Even though you have yet to become a Weapon Refinement Master, I'm sure you understand how difficult it is to refine weapons. It's already difficult enough to create a single graded spirit weapon, let alone a set."

The mention of that had Su Zimo's heart skipping a beat.

Everything else aside, it wasn't really difficult for him to create a set of almost identical inferior-grade flying swords.
