Before Qin Ge's cannon could be manufactured, the enemy came without warning.

A huge explosion sounded in the royal city, and when Qin Ge rushed out of the secret workshop, what he saw was thirty-five huge iron birds swooping from the sky, throwing strings of black bumps behind their buttocks, and behind these iron birds, the gray lord knights of Zihuan chased and intercepted in vain, and the feathered arrows shot out could not break through the defenses of these iron birds at all.

"This is a steam fighter, damn it!" With a scolding scold, Qin Ge knew who the enemy was, it should be the ancient steam mechanical civilization in the east.

"Siege crossbow!"

When Qin Ge shouted, the siege crossbows in the royal city also began to exert their might, these steam iron birds were very fast, they could reach a speed of six hundred kilometers per hour, much faster than the gray owl knights, but once they entered a low altitude of three thousand meters, the dragon hunting level siege crossbows would be launched immediately!

In the blink of an eye, hundreds of crossbow guns with sonic boom afterimages caught up, and the feathered arrows couldn't break through the defenses of these steam iron birds, which didn't mean that the dragon-hunting level siege crossbows couldn't do it.

In an instant, thirty-two of the thirty-five steam iron birds were hit, but only fourteen fell.

These steam iron birds are far more resistant to beatings than warplanes on Earth.

Of course, it still didn't work, because the second wave of ballistas had already struck and knocked down all the steam iron birds without a single one.

After all, this is the Gale King City, the air defense system is the most dense, with a hundred air defense towers, three hundred dragon hunter-level siege crossbows, and a thousand hunter-level siege crossbows can perfectly block the entire area, except for the shortcoming of effective range.

If the Steam Iron Bird can fly above 3,000 meters all the time, then all siege crossbows will have to rest.

Then at this time, Yu Yue and Zhao Xin can only be dispatched.

"Advanced civilization is really difficult to deal with! If I face the army on Earth, I have almost no way to restrain myself. Qin Ge sighed, and ordered Zhao Xin Yuyue to be ready at any time, and at the same time ordered the whole army to be on alert.

"Wait, what is that?" When Qin Ge climbed an eighty-meter-high air defense tower, he was suddenly stunned, only to see that in the south of the kingdom, it should be the direction of the Great Wall on the southern line, and the sky was covered by a huge black shadow, but it was obviously not a dark cloud, and the other could see the appearance of fire rushing to the sky.

"Nima, isn't this an airship? a steam airship? It's almost as big as a mountain, and how many steam airships are there?"

Qin Ge was simply dumbfounded.

"Your Majesty, the Great Wall on the southern front is in an emergency, the enemy army is too strong, with thirty war fortresses like mountains, and the magic weapons on it are very powerful, and our gray lord knights are completely torn apart only a few hundred meters close!"

The Great Wall on the southern front has been destroyed, our army has suffered heavy casualties, Marshal Changqin only destroyed two sky fortresses and was blown into mud, and now our army has been routed on all fronts!"

"Your Majesty, Marshal Roland was seriously injured, and our cavalry cluster was destroyed by the opponent's Sky Fortress!"

"Your Majesty, in the southeast, a large number of enemy marines appeared, they were all hidden in the iron shell, after Marshal Zhang Cheng launched a charge, the troops suffered heavy casualties, and Marshal Zhang Cheng's whereabouts are unknown. ”

All kinds of unfavorable information came, which also made Qin Ge's brows furrow, he really didn't expect that the development level of this steam mechanical civilization was so high, and the third-order soldiers were not opponents at all.

In addition, the Sky Fortress, that is, the steam airship, is really difficult to deal with, there must be a large number of steam cannons on it, otherwise the combat power of the Changqin will be blown up alive.

In addition, the opponent's ground forces definitely have steam tanks, steam armored vehicles, and the like, and the third-order Desert Sword Saint can't do it.

"What should I do?"

Qin Ge was also a little panicked at this time, because the enemy's combat power level was not the same as his kingdom's combat power level.

"That kind of steam airship is the most tricky, it is simply a super-large bomber, and without a strong enough air supremacy, no matter how powerful the ground forces are, they can't withstand a bombardment. ”

"For today's plan, Zhao Xin and Yu Yue can only be dispatched. ”

"Order, let Zihuan, the leader of the Sky Knights, come to see me!"

"Order, Praetorian Legion, the Great Wall garrison assemble immediately!"

"Zhao Xin, Yu Yue, come and see me!"

Qin Ge issued a series of orders, and he had already decided to personally lead the Praetorian Guard and the Great Wall garrison to meet the opposing ground forces.

"Your Majesty, we have been ambushed by the enemy's Iron Bird, the Purple Ring Commander has been killed in battle, and there are only thirty-two people left in the Sky Knights, and we are no longer able to effectively reconnoiter the territory of the kingdom. ”

A bloodied gray owl knight sent back the latest news, which immediately made Qin Ge's heart sink.

"Your Majesty, a large number of iron birds have flown out of the enemy's sky fortress, about 1,000 or so, and are bombarding our east and west Great Walls, and we cannot effectively contain them, and Marshal Konoha's heavy crossbow battalion has suffered heavy casualties and asked to retreat. ”

"Permission to retreat to the Great Wall to the north!"

Qin Ge's head is big, the east and west sides of the Great Wall belong to the newly built, the number of defense towers and the number of siege crossbows are insufficient, in the face of more numerous, faster steam fighters, it is indeed helpless, under the enemy's level of attack, the Great Wall defense system he built has completely become a joke.

"Your Majesty, we are ready. ”

Zhao Xin and Yu Yue came quickly, already knowing what they were going to do this time.

"Go ahead and take out the other party's Sky Fortress. ”

Qin Ge left a little starlight on Zhao Xin and Yu Yue, because this is an act that is equivalent to death, Changqin's combat power is more powerful than Zhao Xin, but he only destroyed two steam airships and was killed by the bombardment, he didn't think that Zhao Xin and Yu Yue could come back alive, so what he could do was to bring the two of them into the resurrection range of the Gray Ear Totem, and let them become non-overlord heroes like Liu Cheng and Chu Dongnan who could be resurrected.

Zhao Xin and Yu Yue did not hesitate, and each rode a gray owl and soared into the sky.

"Order, Mountain Eagle commands the Ranger Battalion, responsible for the defense of the Gale King City and the Great Wall in the north. ”

After giving the order again, Qin Ge led 20,000 Praetorian Guard Corps and 100,000 garrisons of the Great Wall out of the city from the north, and marched quickly and rapidly to the east under the cover of the Great Wall.

Because the enemy's ground forces have already swooped in from the southeast and due east, and their numbers are very large, there is no point in hiding inside the Great Wall at this time.

The 500 kilometers of the Great Wall in the north currently have the most complete air defense system, a full 1,000 defense towers, a large number of hunter-level and dragon-level siege crossbows are arranged here, which can completely pose a huge threat to the enemy's steam iron birds.

In fact, it was true that the situation had already begun to stabilize as Qin Ge's troops quickly understood the nature of the steam iron birds, such as on the Great Wall on the east and west, where the elite gale heavy crossbowmen began to try to shoot the bombs that were dropped in the sky.

On average, a group of 10 people launched intensive sniping, and at an altitude of 800 meters, most of the bombs could be detonated in advance, and by 500 meters, basically no bomb could fall.

However, in addition to the bombs, there are also the steam heavy machine guns that come with those steam iron birds, and the bullets that splash down like water will kill and wound one another, but in this way, those steam iron birds must drop in height, and then they will be fired by the hunter-level siege crossbow in a few seconds.

The two sides went back and forth, and Konoha's heavy crossbow battalion was suffering a large number of casualties every moment, but the enemy's steam iron birds were also fewer, and they didn't even have the strength to break through the defense line of the Great Wall to the north.

Under such circumstances, Konoha's heavy crossbow battalion finally won the opportunity to retreat, and began to retreat into the defense line of the Great Wall to the north and reorganize the defense.

At the same time, due south, 28 mountain-like steam airships are also advancing to the north, the Great Wall on the southern front has been completely blown into ruins, and the legions and civilians are retreating like crazy, thanks to the slower flight speed of those steam airships, the speed is only twenty kilometers per hour, otherwise no one can resist the bombardment all the way.

But beyond the Great Wall to the east, the steam tanks and steam armored vehicles that could not be seen at a distance were rushing over, following the ruins of the Great Wall, heading straight for the Gale King City at a speed of 60 kilometers per hour.

After receiving this news, Qin Ge immediately led a large army through a fortress and went to intercept it, he could not let the enemy's ground troops rush to the front of the Great Wall, and the consequences were very serious.

After all, the defense line of the Great Wall in the north has the most complete air defense system at present.

As for whether he could use his flesh and blood to block the steel torrent on the opposite side, Qin Ge still had some confidence.

Because he brought out all the fourth-order soldiers.

Qin Ge's army traveled extremely fast, which was also a great advantage, the speed of the steel torrent on the opposite side was only sixty kilometers per hour, but they could easily reach one hundred and twenty kilometers.

So half an hour later, the two sides met.

Sure enough, on the other side were all kinds of steel monsters, spewing black smoke, screaming, and the huge barrels looked terrifying.

Two kilometers away, those steam tanks began to fire, but what they fired was actually a solid cannonball, although the power was huge, the middle one would die, but Qin Ge was relieved, and with an order, a thousand fourth-order Storm Sword Saints took the lead in charging.

It was like a thousand tornadoes, approaching in the blink of an eye, Qin Ge's eyes widened, he looked carefully, and then he saw countless tiny projectiles spraying out of the steel torrent on the opposite side, like a salvo of a rifle.

But such a salvo is not much damage for the Storm Sword Saint, who is already a fourth-order, after all, this is a fourth-order class that has filled up the defense and transferred with red crystals.

In the blink of an eye, the sword light roared, and a thousand steam tanks with a head were slashed in half by these thousand fourth-order Storm Sword Saints, while the infantry hiding behind the steam tanks disappeared simultaneously.

"Earth Ranger, hurry up!"

Qin Ge gave the order again, he was finally relieved, the fourth-order Storm Sword Saint was really still his father, what kind of steam tank, the steam armored car could be split with a sword, but there were a lot of infantry behind the tank armored car on the opposite side, and he couldn't bear it if he concentrated the fire for a long time.

In fact, in just these ten seconds, dozens of fourth-order Storm Sword Saints had already died.

"Predator Knight, outflank the left and right wings. ”

"The garrison of the Great Wall, fully pressed!"

Qin Ge gave the order to charge, there was nothing to say, it just depends on whose fists are harder.
