Chapter 542: Zergs At The Doorstep (2/2)

Everyone knew that as soon as the Zergs crossed the line of defense, the mastery casters, which made up the bulk of the humans' offensive force would be unable to inflict any meaningful damage to the enemy.

The forest of concrete and cement, as well as the twisted alleyways, provided cover for the human defenders. In addition, since the Zergs had already made a home in this city, even the brutes in the Zerg army would tread carefully and try not to damage any of the structures which they used to call home. The Zergs' reservation had given the humans another edge while defending themselves.

After a while, Guan Dongyang and the mastery casters started to cast the spells. Hearing the chanting, the dark ones sent in their flying units; however, the sky was guarded by Yin Tianzong and Vorenus. Unable to best two of the best human fighters, the flying Zergs fell to the ground.

Holding the energy crystals in their hands, the mastery casters pronounced the magical words one word after another as they weaved a hybrid elemental spell using each and every syllable. They had been practicing this hybrid spell for months, and by now, they could cast this powerful spell even with their eyes closed. Only the original mastery casters from the Battle Wolf had partaken in the casting, and those casters from the Divine Mastery sect were ordered to stay put for now. Casting such a powerful spell required tremendous energy, and resting was necessary after each casting. The second team of casters would need to keep the pressure on the enemies during the first team's rest.

The front edge of the Zergs' formation was near, and behind them was a dark sea of monstrosities. A few dark ones were scattered around the roiling sea, their glinting eyes looking like the moonlight reflected off the sea waves.

The dawn-lit sky was brightened by a warm red glow, and in a blink, the red glow turned into flames, setting the sky on fire. The fire sucked the power out of the energy crystals as the latter dimmed. As the fire danced more violently, the sky started to spin. A second later, the dancing flames gathered together and formed a tornado which quickly grew in size and brightness. The mastery casters' eyes were lit up with anticipation and the promise to kill. There was no way back: this was the final battle!

The fire tornado wiggled its tail like a dragon, but it didn't lash out at its target; it was waiting for them to get closer.

Sweat started to form and trickle down Guan Dongyang's cheeks. The longer he held the spell, the more powerful it grew. At the same time, it got more and more taxing on the casters' system.

The Zergs were still not close enough, hence, Guan Dongyang gritted his teeth and swallowed down the pain while waiting.

When the frontline of the Zerg formation finally reached the defense line, Ross led his warriors out of their covers and engaged them. Not far from the heat of the battle, a column of the casters from the Divine Mastery Sect stood anxiously, waiting for orders. This was going to a long battle, and every soldier counted.

Guan Dongyang waited; he wouldn't unleash the spell until the Zergs' heavy artillery came within the range.

Finally, four Tank Zergs moved their massive bodies across the defensive line and started shooting deadly flames at the human soldiers.

Tornado Fire Drake!

”KOM!”

Guan Dongyang finally unleashed the spell, causing the fire serpent to bear down on the dark sea of Zergs below it. The deadly flame melted the thick shells of the Tank Zergs almost instantly, not to speak of the lower tier Zergs.

The fire drake carved an ugly scar on the moving mass of Zergs and filled the air with the stench of charred meat and chitin. Seeing the powerful spell work, the human soldiers cheered in joy. However, the opening in the Zergs ranks was quickly filled by more of them.

”Formation!” Ross shouted.

The human soldiers tightened their formation and blocked the choke point, leaving only two small exposed sections to engage the attackers. Behind them, the mastery casters from the Sect were already busy at work. Xiao Yuyu had also replaced Guan Dongyang as the caster's captain while the latter recuperated his strength.

The human force had the advantage of terrain, but were outnumbered and outranked. Still, Yin Tainzong and Vorenus were in charge of taking out the dark ones. Leveraging the terrain advantage, the two warriors were able to fend off the attacks of a dozen dark ones at the same time.

Every minute or so, Guan Dongyang would send a dark one to its maker along with an ear-piercing shriek. Not only was he a legendary level warrior, but also a veteran who had survived many wars. Therefore, he was much more powerful than a normal level twenty-one legendary warrior.

The human warriors stood their ground firmly while the Zergs kept on pouring through the choke point. Many of these warriors were survivors of the horror during the Zerg occupation of the city, and therefore, they fought with vindictiveness and courage that were unseen before.

After all, they would rather die while fighting than becoming the Zergs' slaves again.
