A few minutes later, dozens of large red ants with slender legs, thorny carapaces, and two pairs of transparent membranous wings growing on their backs, one long and one short, drilled out of the corpses of the cries one after another, and then quietly crawled on the semi-sandy red earth, motionless. ☆ →, the swarm has not yet attacked, and the soldiers' attention is very distracted, and many people are looking blankly at the bottom of the city wall. In order to avoid being discovered, which would cause unnecessary panic, Iron Slag did not dare to rashly command the scout soldiers to act.

At this moment, the swarm in the distance began to move massively, and seemed to be adjusting its formation. It didn't take long for the thunder beasts to slowly walk out of the swarm and stand at the front, and then groups of frogs followed. At the same time, the stinging insect phalanx in the rear also began to move.

"Roar, roar, roar...... Roar Roar Roar ...... Roar roar ......" The next moment, facing the fortress, the group of thunder beasts lined up suddenly raised their heads and roared in unison. Suddenly, the incomparably thick sound waves stirred the sky and the earth, as if forming a monstrous wave that hit the city wall.

Immediately after, the raised forefeet of the thunder beast group slammed to the ground, stirred up thousands of feet of sand, took heavy steps, and began to charge. In an instant, the earth shook and the sky changed color, as if the whole world was trembling.

"Artillery teams 1, 2, 3, 4, pay attention to the movement of the stinging insects and be ready to shell at any time." Looking at the menacing swarm, Iron Slag picked up the walkie-talkie and calmly gave the order.

"Yes!" Mu Qianhe replied loudly. More than 40 thunder fire types were divided into four squads, which were under her unified command.

"Lava Behemoth, Free Shelling." With the order of the iron slag, a loud "bang" was heard from the top of the fortress, and a huge cannonball was fired at the rushing swarm.

Taking advantage of the fact that the soldiers' attention was attracted by the shelling, the iron slag thought that the soldier ant army at the foot of the city wall suddenly spread its wings, trembled, and flew in all directions.

"Boom!" A few seconds later, there was a flash of fire in the swarm, and the crumbling insect corpses rose into the sky like a fountain, and then a huge explosion came to the face.

However, before the smoke of gunpowder dissipated, countless cries poured out, filling the gap in the advance. In less than five minutes, they were under artillery fire and rushed to a distance of 500 meters in front of the fortress.

"Rocket artillery, fire-gathering thunder beasts." Iron Slag commanded in a deep voice.

As soon as the words fell, the soldiers shouldered the rocket launchers, aimed at the rushing thunder beasts, and pulled the trigger.

"Turbulent ......", "Turbulent ......", "Turbulent ......", "Turbulent ......", "Turbulent ......", "Turbulent ......"

Suddenly, the city walls were full of fire, smoke, and rockets dragged the sparks like fine sand straight to the swarm.

"Boom!" "Boom!" "Boom!" "Boom!" "Boom!" "Boom!" In the blink of an eye, the sound of explosions and hissing were intertwined, accompanied by a ** heat wave rushing towards the city.

In the fierce wind, the iron slag still stood at the edge of the city wall, and its tall and immovable posture stood still. At this moment, he is like a javelin stuck in the city, bringing the last confidence to the soldiers defending the city.

Three or two minutes later, the four thunder beasts rushed to the bottom of the city, and with heavy steps, they launched a ramming attack on the solid city wall. In an instant, they were slammed into the city walls with depleted uranium armor-piercing shells like a torrential rain.

"Bang!" "Bang!" "Bang!" "Bang!"

With four muffled sounds, the city wall shook violently, and the two soldiers were caught off guard, and were directly shaken off the city wall by the huge impact, and hundreds of cries immediately surrounded them, tearing them to pieces in an instant.

At the same time, at the point of the depression caused by the four-headed thunder beast, several self-detonating cries flew from behind and crashed into it.

Iron Slag Eye quickly pulled out the McLin revolver and blasted several self-detonating cries into the air. However, only two of the four dents were shot and killed, while the other two were corroded by strong acids. As far as the eye could see, the walls were melting at a rate visible to the naked eye. The wall has two floors, the first of which is made of steel plates filled with willow nails, and the second is made of reinforced concrete.

After completing the first impact, two of the Thunderbeasts immediately retreated, ready to launch a second impact.

Iron Slag was about to command the soldiers to use rocket artillery to gather fire on the Thunder Beast, but at this moment, a large number of cries followed the huge body of the two Thunder Beasts, climbed the city wall one after another, and pounced on the human soldiers.

In the blink of an eye, the city was in chaos, and the marines drew their daggers one after another and fought with the cries.

Seeing that the shape was in danger, Iron Slag pulled out a single-edged straight sword to join the battle group, and while slashing the Crying Frog, he rushed to the climbing mouth of the city wall.

Inadvertently, a self-detonating crushing frog rushed up to the city in the midst of an ordinary crier, silently and silently swooping towards the densest concentration of human soldiers.

At this moment, the iron slag a few meters away happened to kick an oncoming cry fly, and as soon as he turned his head to see this scene, he immediately saw that the self-detonating cry exploded among the five or six marines. Suddenly, the green fluorescent acid splashed on the soldiers' bodies, and the terrible wails suddenly resounded in the sky. The thick acid was like boiling oil, and in an instant, the tarpaulin uniform was eroded to a thousand holes, penetrated through the clothes, and sticked to the skin with a sizzling sound. In an instant, pungent white smoke rose from the pungent white smoke, corroding the flesh and life of the soldiers.

Looking at the miserable situation of the soldiers, Iron Slag closed his eyes, gritted his teeth, but when he didn't see it, he immediately rounded the big sword, swept away the two cries in front of him, tore off the two fragmentation grenades on the soldiers next to him, rushed to the climbing mouth, bit the pull ring, kicked away the cries that had just pounced, and smashed them down with all his might!

"Boom!" "Boom!"

Amid the violent explosions and tumbling waves, the thunderbeast below let out a loud wail. The iron slag didn't stop for a moment, glanced around, picked up the iron gallant rocket launcher on the ground, jumped onto the low wall on the edge, and aimed at the side of the thunder beast below with a height difference of less than ten meters, and blasted out!

In an instant, rockets burst out, "Boom! With a loud bang, the thunder beast exploded its body and tilted its body to the ground. The iron slag on the head of the city was also swept over by the blast wave, and because the shooting distance was too close, countless rocket fragments splattered out, slashing him up and down with blood, and there were several more scars on his face alone.

However, the iron slag that had just landed immediately climbed up, found the second rocket launcher, jumped on the low wall at the head of the city, and fired another shot at the thunderbeast that was struggling to get up below!

"Boom!" After a bang, the giant beast under the city was blown down. At the same time, the shrapnel flew out, scattering the cotton wool of the military uniform.

After losing the Thunderbeast's body as a bridge, the speed at which the Cry Fly climbed the city wall dropped significantly, and the pressure on the soldiers suddenly decreased. At this time, many soldiers were already red-eyed, looking at the iron slag fighting method of exchanging injuries for injuries, they followed suit, looking around for the rocket launchers scattered on the ground, and then fired desperately at the thunder beast below!

When more than a dozen rockets bombarded the back of the thunder beast at close range, the thick iron shell finally shattered, spewing out a large amount of dark green slurry,

I saw its limbs burst apart, its carapace pieces fell off, and finally it let out a heavy wail, and finally fell to the ground. Seeing this, Iron Slag wiped the blood from his face, and was about to breathe a sigh of relief, when the starlight suddenly dimmed above his head, he hurriedly pounced forward, rolled his body, and hid behind the low wall.

"Boom ......Boom T

In the next second, countless pale spikes fell from the sky and fell on the city like a shower, wailing for a while, and the cries continued.

When the iron slag looked up again, he saw a soldier standing upright on his back, his hands twitching unconsciously. When he looked closely, he saw a spike burst out of his chest and nailed him to the wall. At this moment, white smoke kept rising from his chest, and the expression on his face was extremely hideous, as if he was suffering unspeakable pain.

Iron Slag exhaled heavily, stood up, and stabbed the soldier in the heart with a sword, reducing his pain.

"Shelling! Shelling! Looking at the phalanx of stinging insects in the distance, Iron Slag shouted loudly with a walkie-talkie. At the same time, with a thought, he commanded the scout ants to fly towards the swarm of stingers, and then picked up the binoculars and quickly reported the direction of the shelling.

"Brothers, please hold on a little longer." Immediately came from the intercom, Mu Qianzuru's soft voice.

At this moment, a second salvo erupted from the stinging insect phalanx in the distance. In the blink of an eye, countless pale spikes plummeted along the parabola.

Before the iron slag could stand up straight, the two thunderbeasts that had gone and returned launched a violent collision/strike on the city wall! There was only a loud "clang", and they slammed their heads into the hollow gap, and the entire city wall shook violently.

"The wall is broken!" "They're in!" "Plug it up!" "Brothers, fight with them!" Suddenly, the frightened shouts of the soldiers came from the walkie-talkie.

The iron slag quickly climbed down the wall, only to see that the wall below had been knocked open with a large opening, and the swarm of cries was rushing in. And the soldiers blocked the gap and fired frantically, and one after another the fragmentation grenades smashed through.

"Ju Amu, drive a truck!" Iron Slag shouted at the walkie-talkie, and with that, he pulled out the McLin revolver to join the warband, firing desperately at the gap.

Suddenly, a thunder beast squeezed in through the gap, breaking through the encirclement with a dense barrage of bullets, knocking the soldiers around the gap to pieces.

"Arnold!" Seeing that the city wall was about to fall, Iron Slag hurriedly summoned a team of psionic warriors.

"Wait! We're still in the southeast! Arnold shouted.

At this moment, three dazzling blue rays of light shot directly at the back of the thunder beast, blasting its huge insect body crookedly. When I looked up, I saw porcupine, matchstick, and Tuoba standing side by side at the head of the city, holding a psionic warrior rifle in their hands.

Under the huge impact force, the thunder beast had a momentary frustration, taking advantage of this gap, the iron slag bullied up, jumped up, turned over the back of the thunder beast, and plunged towards the wound caused by the psionic armor-piercing bullet just now!

"Roar!" Sharp pain came from its back, and the thunderbeast let out a roar that shattered its eardrums, and shook its body like thunder, trying to shake the worm off its back.

However, at this moment, the iron slag tightly grasped the hilt of the sword, and in the violent shaking, pulled out the large revolver and blasted towards the thunder beast's head at close range!

"Bang!" "Bang!" "Bang!" "Bang!" "Bang!" Five bursting bullets hit the thunder beast's head in a row, instantly sending it to the ground of flesh and blood. After firing the bullet, Iron Slag immediately threw away Merlin's revolver, and with a force of his hand holding the hilt of the sword, he turned over, and with the other hand, he tore off a shrapping grenade hanging on his chest, bit the pull ring, and forcefully stuffed it into the wound on the back of the thunder beast, and then let go of his hand, ready to roll off the back of the thunder beast.

But as soon as he let go, he was thrown away by the thunder beast's incomparable force, and rolled backwards unbalanced, and as a result, in mid-air, he was kicked by the thunder beast's raised hind hooves, and immediately flew straight behind like a cannonball, and hit the side wall hard.

At the same time, the fragmentation grenade stuffed into the thunderbeast's body exploded, exploding juice and kicking off large swaths of carapace and flesh.

After the iron slag hit the ground, as soon as he struggled to get up, he spurted out a large mouthful of blood.

In the face of the battered thunder beast, the soldiers surrounded it in one fell swoop and killed it completely. But before they could catch their breath, another thunderbeast squeezed in from outside. And their leader, who was on the side of this thunder beast at the moment, didn't seem to have recovered yet.

"Horn Horn Horn ...... Horn Horn Horn ...... Horn Horn Horn ......" Get out of the way! Get out of the way! Get out of the way! At the last moment, the horn of a truck was suddenly heard behind him, as well as the roar of the engine and the rapid shouting. The soldiers rushed to the left and right, and in an instant, a large truck roared from the rear, slamming into the thunder beast that had just squeezed into the gap!

"Bang!" With a muffled sound, the thunder beast and dozens of cries were suddenly hit back by the heavy truck.

After the violent impact, the bloodied giant Amu rolled out of the cab, limped to the iron slag, helped him up, and got out of the front-line battlefield.

At the same time, the soldiers quickly surrounded the past, taking advantage of the obstruction of the trucks, re-plugged the gap, and fired wildly outward.

It didn't take long for the iron slag to recover from his vertigo, and he struggled to his feet and rejoined the fight......
