At the sight, the Second Elder's expression changed. The damned Black Water Sect had actually deployed its most powerful Demonic Soul Spirit Cannons. A few more attacks, and Skyward City would be in danger...
The Second Elder immediately shouted an order: "Reinforce the frontal defenses! Qing Xuan Spirit Cannons, return fire!"
"Focus the defenses! Keep your eyes on the front!"
"Foundation Establishment disciples! Assist with the defensive restriction formation!"
At the Second Elder's command.
Among the Qi Refining Realm disciples stationed within the Formation Pillars, some swiftly operated Formation Flags, while others rapidly chanted incantations and formed hand seals, releasing spell power into the formation's Formation Disks...
All of a sudden.
As the formation's spell power poured steadily into the defensive Restrictive Barrier, which had been shaking relentlessly under the Spirit Cannon bombardment, mysterious, profound runes began flowing across its entire surface...
The defensive Light Barrier rippled continuously in an instant, and after a wash of radiance, its defensive strength soared.
Large-scale defensive formations and restrictions generally worked this way. Whichever direction came under attack, the corresponding section could be activated and supplied with increasing amounts of spell power. This strengthened the defenses on that side while also conserving the formation's spell power...
Sure enough!
Boom! Boom! The massive Spirit Cannons on the other two enormous Flying Boats fired...
Two beams of gray light, each dozens of zhang wide, blasted toward them and struck the frontal defensive restriction...
Boom! Rumble!
Two violent explosions erupted. Bursts of gray light surged outward and scattered in every direction. Rings of ripples coursed across the frontal defensive Restrictive Barrier, but with the formation's spell power pouring in, the barrier remained completely intact.
At that moment.
Within Skyward City, Spirit Cannons slid out from various locations across the mountainside. Disciples loaded cannon shells into them
