Under Min Longyu's command, the Luo Tian Association's Five Elements Squad began splitting up to launch probing attacks against the Copper Walls Iron Walls Grand Formation.
With every probe, Min Longyu also passed down basic formation knowledge to those below him.
It was not because he was generous; rather, only after understanding the simplest positional knowledge could these cultivators be put to better use by him.
"First, understand the positions corresponding to the Eight Trigrams. Qian is one, Dui is two, Li three, Zhen four, Xun five, Kan six, Gen seven, and only then Kun eight."
"Qian and Kun are Heaven and Earth..."
"Gen is Mountain, Dui gives rise to Marsh. Fire Element Squad, attack the Dui Palace position and test the strength of water and fire there!"
Upon hearing Min Longyu's command, the separated Fire Element Squad immediately cast fire-element spells and attacked the Dui Palace position in unison.
Under the clash of water and fire, sheets of golden ripples spread across the formation's light screen.
Min Longyu's expression turned thoughtful at the sight.
"If water is strong, that means metal is even stronger. This formation mainly relies on metal and earth, with its power chiefly bolstered in the metal element. The earth element has instead become mere window dressing."
"Water Element Squad, use the Wave Technique and see how it reacts!"
The nineteen members of the Water Element Squad immediately formed hand seals and cast their spells together.
Great rolling waves surged forward in vast swathes.
Provoked, the golden light screen blazed brilliantly.
Faintly, sheets of golden liquid seemed to flow slowly across it, and the light screen appeared to gain an overwhelming presence.
Earth gave birth to metal, and metal gave birth to water.
The three complemented one another, forming Copper Walls Iron Walls—hard yet resilient, impregnable.
