The swarms within the range of these spells were instantly pulled into the air by a tremendous force and torn apart by countless wind blades slicing through them continuously.

  At the same time, a massive number of wind blades spread outward from the cyan tornado at the center, forming large-scale sweeping attacks.

  A Hydralisk advancing on the battlefield had just reached the outer edge of this enormous tornado. Just as it was about to turn and evade this terrifying spell blocking its path, one of the countless cyan wind blades carried by the tornado swept in from afar, slashing across its body.

  The Hydralisk was instantly sliced in half like a piece of tofu.

  The fireball barrage covering the charging route of the knight legion suddenly weakened after the cyan tornado formed.

  This change gave the knight legion, which had been making a desperate charge under the relentless explosions, a chance to break free from the fire-covered zone—though at a heavy cost.

  "It's the mage legion's large-scale magic!"

  "Our reinforcements have arrived!"

  "For glory! Victory shall be ours!"

  Seeing this large-scale spell appear reignited the knights' hope. Their desire to survive even triggered some of them, upon escaping the explosion zone, to ascend to the extraordinary rank directly on the battlefield. A faint aura of battle energy ignited around them.

  Unfortunately, after they broke through the firepower coverage, what awaited them was an entire force of extraordinary-level mutated Zerglings.

  The wind blades that had spread from the tornado—capable of easily slicing through Hydralisks—only caused the mutated Zerglings to tremble slightly upon impact. The blades left blood-red marks on their armored scales before dissipating into the air.

  As the heavily damaged knight legion collided head-on with the mutated Zergling formation, a one-sided massacre crushed the brief hope they had just rekindled.

  The mutated Zerglings, their scythe-like arms enhanced by wind blades, effortlessly cleaved through the knights, cutting both riders and warhorses in half.

  Their standard enchanted armor was easily penetrated by the attacks of the extraordinary Zerglings. Meanwhile, the knights' longswords and lances could only leave faint marks on the Zerglings' 【Toughened Skin】, struggling even to break through their defenses.

  At this moment, William had already turned his gaze toward the rear of Mary’s vassal army.

  There, 500,000 mages had formed 50 massive magic circles, each centered around an elite-level mage.

  Cyan energy flowed rapidly within the circles, and the fluctuations of magical power grew stronger by the second.

  Above the insect tide, the first batch of 50 cyan tornadoes had yet to fully take shape, while the second batch was already being formed.

  This was a sustained-channeling spell. As long as the mage legion continued to pour magic into it, the wind-element tornadoes would multiply in number and grow in power.

  Upon recognizing this as the result of a coordinated spellcasting effort by the mage legion, William glanced indifferently at the flying Zergling horde in the sky.

  Even before he could tug on the faith link, the massive swarm of flying Zerglings had already begun to shift.

  The creatures folded their wings and instantly transitioned from gliding in the sky to a full-speed dive.

  The 【Wind Shield】 enveloping their bodies transformed into a semi-transparent, streamlined barrier, further increasing their diving speed.

  In the blink of an eye, the dense insect cloud descended like an apocalyptic storm, crashing down upon the mage legion in the rear.

  Just as the diving Zerglings neared the massive spell formations formed by the mages, a transparent protective barrier materialized above the mage army.

  Unfortunately, this thin defensive shield was facing a swarm of flying Zerglings enhanced by both 【Toughened Skin】 and 【Wind Shield】.

  The barrier was instantly pierced and shattered as the creatures plowed through it in their dive.

  Within moments, the 500,000-strong mage legion was engulfed by a sea of insects.

  With the coordinated spellcasting disrupted, the enormous cyan tornadoes in the sky rapidly dissipated the moment the mage legion was overwhelmed.

  The now-defenseless magic army was completely devoured by the relentless insect tide as it continued its advance without pause.

  As Mary’s demigod projection fully dissipated from the sky, William watched the insect horde continue its unstoppable march toward the horizon, a satisfied look on his face.

  Mary's defensive line had failed to offer even the slightest resistance against his new tactical system. From start to finish, the insect swarm’s advance had remained uninterrupted.

  Moreover, after the entire battle, the losses inflicted on the three hundred million-strong insect army were so minuscule that they were negligible.

  "The new tactics performed well. Pity the enemy wasn’t strong enough, so I didn't get a chance to deploy the self-destruct Zerglings."

  "Also, the Hydralisks' weakness was exposed. Their bodies are too fragile—this needs to be improved. Their defensive capabilities must be enhanced."

  After summarizing the results of this test of his swarm’s new tactics, William activated the faith link.

  Ten thousand flying Zerglings broke off from the aerial swarm and began circling over the battlefield that had just been ravaged by the insect tide.

  William had assigned them the task of cleaning up the battlefield after the main swarm had fully passed through.

  Their orders were simple: consume anything edible and gather anything useful, leaving behind nothing but rock and dirt to be transported back to his divine realm.

  Having set these arrangements in place, William briefly scanned the map in his consciousness.

  On the other end, the orc army had already vanished beneath the path of the insect tide—an expected outcome that did not concern him.

  He simply checked through the faith link to get an estimate of the losses sustained by that segment of the insect army.

  "Hmm… losses are essentially zero."

  With that confirmation, he also instructed the flying Zerglings on that front to form a small cleanup team after the battle.

  After handling these matters, William turned his attention back to the main army still stationed at the invasion passage.

  By now, the entire insect swarm had completed its entry. However, since they had not yet received his command, they remained in place, resting in silence.

  "Move out."

  As the command was transmitted through the faith link, the massive seven hundred million-strong main army began to stir.

  The silent, purple-red swarm covering the ground surged into motion.

  The flying Zerglings took to the skies, forming their signature swirling insect cloud.

  The mutated Zerglings led the charge at the vanguard, followed closely by nearly four hundred million Hydralisks forming the central force.

  Bringing up the rear were twenty million self-destruct Zerglings and one hundred thousand Thunder Wyverns—hidden aces dispersed within the sea of insects, advancing with the main force.

  Under William’s control, the army began its slow march toward the vast plains at the center.

  Since there was no immediate target, he deliberately slowed the swarm's advance.
