If Heaven hadn't given birth to me, I would be arrogant.

Everyone stayed up all night, standing on the eastern city wall, watching the enemy camp a kilometer away. They knew that since the aliens had buried gunpowder in the western city wall, the next day might be the day they launched their general attack, so everyone was quietly observing.

Sure enough, as soon as a sliver of white light appeared on the horizon, the alien army a thousand miles away began to move, causing everyone to tense up. However, a moment later, they were all puzzled, because they could clearly see that the alien army had indeed moved, but not in an attack; instead, they were slowly retreating until they had withdrawn more than two thousand miles before stopping!

The enemy's unusual movements filled Zong Ze with a sense of foreboding. Suddenly, he realized something!

"Gentlemen, how far is our first line of defense, composed of elite warriors, from that section of the city wall?" Zong Ze asked.

"One kilometer!" a commander replied. "To effectively prevent the enemy from entering, we will set up our first line of defense one kilometer inside the city walls!"

"Retreat!" Zong Ze hurriedly said, "The alien race must have made a meticulous plan. The power of the gunpowder explosion inside the city walls must be extremely great, which is why the alien race chose to retreat. They are afraid that the power of the explosion will harm them!"

As soon as Zong Ze finished speaking, everyone immediately realized why the alien race was not only not attacking, but was retreating!

The messenger quickly went to deliver the order.

Just as the messenger returned to report that the first line of defense had been safely withdrawn two kilometers, a flying elf suddenly flew out from the enemy's alien army!

This one flying elf flew straight toward the western city wall. When it was still two hundred meters away from the wall, the flying elf stopped. It first looked back at the location of the alien camp, and then took out three arrows with a resolute expression. There was a faint light coming from the arrowheads!

"Whoosh!"

The flying elf released its left hand, and three arrows, glowing with fire, shot straight toward the city wall.

"boom!"

With a deafening roar, everyone on the city wall, including Han Feng, who possessed the cultivation of a Martial Venerable, lost their footing and were knocked to the ground. Instantly, everyone's eardrums seemed to be torn apart, and they could no longer hear any sound. Although they could see each other opening their mouths and shouting something, all they could hear was a series of buzzing sounds!

The tremors lasted for a full quarter of a day, until they finally subsided, and the commanders were able to hear a faint sound again. Meanwhile, most of the ordinary soldiers of the Duchy of Jade, who were also guarding the city walls, had blood trickling from their ears; their eardrums had ruptured, and they would never hear a sound again.

Looking in the direction from which the explosion came, nearly 20 miles of the western city wall, which covered a distance of 50 miles, had been razed to the ground. In the rest of the city wall, it was no longer a city wall. In better places, traces of the city wall could still be faintly seen, but in most places, it had become a mound of earth!

Within two kilometers of the city walls, all the houses collapsed, the entire area was filled with dust, and there were broken bricks and tiles everywhere. This was a natural disaster, a man-made natural disaster caused by a foreign race.

The border walls that have defended against foreign invaders for thousands of years have been breached today!

Clearly, the alien army was also shocked by the explosion; chaos ensued there, and it took a very long time for things to calm down.

The messenger reported that the first line of defense had suffered no casualties due to the timely withdrawal. However, most people had their eardrums damaged by the violent explosions. But because the five million soldiers on the first line of defense were truly elite warriors handpicked, and Zong Ze had previously instructed them to plug their ears with cotton, their eardrums did not rupture, and their hearing loss was estimated to be only temporary!

Two days had passed, and the aftereffects of the explosion had dissipated. The alien army finally moved; a full three million alien soldiers surged towards the broken wall!

Leading the charge were the two major orc cavalry races: 500,000 wolf riders and 500,000 bear riders. In the middle were another million elven warriors: 500,000 elves on horseback and 500,000 flying elves. Finally, a million dwarves leaped and bounded along. Although the dwarves had no mounts, their exceptional jumping ability gave them speed comparable to cavalry!

"Five hundred meters!" Jin Renmeng was the first to notice the difference among the 500,000 flying sprites: "They can actually reach a flight altitude of five hundred meters!"

"Pass on my orders!" Zong Ze coldly commanded: "The First Air Combat Battalion, the Second Airborne Battalion, and the Fourth Landing Battalion of the Divine Machine Division will all take to the air for combat, at an altitude of 900 meters. Their primary targets are the Flying Elf forces. Requirements: 1. Incapacitate the Flying Elves from ground attacks; 2. If the enemy Mountain Giants engage, increase the flight altitude to 1,300 meters; 3. If the Swan Clan engages, the First and Fourth Battalions will make an emergency landing and switch to ground forces to support the Third and Fifth Battalions! If the Second Battalion suffers a devastating blow, it will immediately be airdropped!"

"Third Special Forces Battalion, Fifth Logistics Battalion: Ground operations, focus all firepower on the enemy cavalry, and try to engage the elves in hand-to-hand combat!"

A series of orders were issued, leaving the commanders dumbfounded. Now, including Moses, they finally understood why Zong Ze had been so insistent on commanding the Divine Machine Division. It turned out they simply lacked the ability to command such a multi-functional fighting force. Just listening to the technical jargon they used made it clear that their own command skills were utterly inadequate, not even fit to carry their shoes!

A thousand hot air balloons took off at Zong Ze's command and quickly arrived above the first line of defense. However, they did not stop, but flew straight towards the ranks of the three million alien army!

The sudden ascent of the hot air balloons and their terrifying altitude made the alien army uneasy. Their own people were right; 600 meters was not their limit at all. If there hadn't been only a thousand of these large balloons, which was a small number for a force of three million, Luo Tian would have really had to send out reinforcements!

The two armies clashed quickly, and in the blink of an eye, the alien army had passed through the collapsed city walls and rushed towards the first line of defense. The hot air balloons' interception only took the lives of 50,000 flying elves, while the ground troops' archery only killed about 20,000 orc cavalry.

"boom!"

The two forces clashed violently. Right on this first line of defense, the elite human warriors used their own bodies to fiercely block the three million-strong alien army that was charging forward.

In an instant, the sounds of battle shook the heavens. Curved swords clashed with spears, and the roars of alien war wolves and bears, along with the neighing of elven warhorses, rose and fell. Yet, none of this could suppress the heartfelt roars of the elite human warriors. Not a single warrior's face showed fear. Every fallen warrior, whether their heart was pierced and blood flowed freely, or their intestines were pulled out and they died with their heads tilted back, had a smile and hope on their face.
