The City of Steel, a city made entirely of steel, stands majestically above the earth, with piercing sirens sounding over the city, and the streets have long been evacuated.

Rows of elite soldiers entered their respective areas in an orderly manner to defend.

Although the culprit of the attack is the type IV xenomorph, according to the characteristics of the xenomorph, there will definitely be a large number of low-level xenos following, and no one can guarantee that there will be any low-level xenos who will take advantage of the gap in the battle to break in.

So every time you are attacked, a full defense is essential.

On the periphery of the Iron City, a big man wearing black exoskeleton armor and a tiger's waist and a bear's back on the iron wall defense line shouted at the top of his voice!

"Cheer me up, we will never allow any kind of xenomorph to cross the iron wall, this is our pride! We will defend it with our blood at all costs! ”

"Bloody battle to the end!!"

"Bloody battle to the end!!"

"Bloody battle to the end!!"

……

The soldiers on the entire iron wall responded with hysterical roars, it was a kind of blood and glory as a soldier.

Not far away, a group of squads wearing gray exoskeleton armor watched all this with cold eyes, and they all had unique marks on their chests, the swift squad of the G department.

Although Wang Quan opened his mouth, the Steel City did not need much support.

However, the G Department team stationed in the City of Steel also moved, but the atmosphere seemed a little out of place.

A member of the team asked the captain in a low voice.

"Captain Luyou, what is our mission this time?"

"It's okay to assist in defense, the main force will be handed over to the fighters of the Steel City, and temporarily obey Zou Kai's command." Lu You (Swift Squad Leader) couldn't help but look at the big man.

(Zou Kai is subordinate to the commander of the Second Army of the Steel City, with the rank of lieutenant general, responsible for guarding the iron wall defense line of the Steel City, and his eldest brother is the lord of the Steel City.) ）

The City of Steel is still very different from other cities, the whole City of Steel is a semi-military city, and the people here are fierce! Heavy industry is well developed, and the people who live here are basically proud to be in the army.

The Zou family has a very strong influence in the Iron City, of course, this is not for nothing, almost every heir of the Zou family has joined the army, but more than half of the personnel have died in the war to defend the Steel City.

So it has been in the past, and so it will be in the future!

Of course, thanks to big cities like Steel City and Dragon City, the small cities in the rear can be peaceful, but in fact, it is only because the Dragon Xia Kingdom has actually fallen nearly half of its territory, which will cause the important main city to be exposed on the front line, which is really helpless.

At this time, Lu You seems to be a very wise choice, but in fact, it is more of a helpless move, and the stage here does not belong to them.

Zou Kai didn't feel Lu You's gaze at all at this time, of course, even if he did, he wouldn't care, his tense face looked into the distance!

Although he couldn't see the enemy yet, he could already feel the aura of death in the air.

Rumble~

There was a loud bang at the bottom of the wall of the heavenly dome, and a huge crack appeared in an instant.

The whole earth has begun to shake violently!

"Prepare for !!" Zou Kai put on his exoskeleton helmet and shouted.

"Yes! Shogun! ”

Suddenly, the soldiers on the ironclad defense line activated the fixed weapons on the defense line.

PITCH-BLACK LARGE-CALIBER SELF-PROPELLED GUNS STRETCHED OUT, VULCAN G-03 HEAVY GREEN, 7MM CALIBER BULLETS, AND THE RATE OF FIRE CAN REACH 12,000 ROUNDS PER MINUTE WHEN FIRING AT FULL STRENGTH.

This was followed by a large number of muzzles and missile launchers.

At this moment, countless sand and dust rolled up in the distance!

In Zou Kai's eyes, there were red dots everywhere in the dust rolled up in the distance!

"Damn it!" He cursed under his breath, it was clear that the Type IV xenomorph had stirred up the tide of xenomorphs! IQ is not generally high!

Zou Kai raised his hand high, and everyone in the entire battlefield held their breath, waiting for the order to attack!

Zou Kai's eyes were staring at the ever-approaching tide of xenosia!

Ten kilometers! Nine kilometers!

……

Three kilometers!

1000 meters! 800 meters!

Attack!!!

Bang~~~

The rain of bullets in the sky accompanied by cannonballs instantly fell into the tide of xenos!

Explosions resounded in the sky to kick off the war in the Iron City!

In the refuge area of the C3 area of Dragon City, Su Bai, Ergouzi and others were almost straight, and they saw that the image switched to the steel city.

A middle-aged reporter was very dedicated to standing on the iron wall and preaching.

"This is the Iron City Iron Wall Defense Line, the xenomorph tide has begun to storm the defense line, we can see that the battle is very fierce, the number of xenomorphs coming is very large, it is impossible to count the number for the time being, but I believe that the Steel City is absolutely invincible......"

Just before the reporter could finish speaking, suddenly a black figure swept over his head.

Immediately after that, the image swirled around, accompanied by screams!

Su Bai and Ergouzi were dumbfounded!

"What's the situation!" Ergouzi asked suspiciously.

"If I'm not mistaken, a Type II crow took him." Su Bai's eyes changed slightly.

"Type II? I see? I thought it was something? By the way, in this attack on the Iron City, what type is the highest likely to appear? Ergouzi asked after listening to Su Bai's words.

"Level 4 warning, it should be Type IV."

"Oh, then there's nothing to be afraid of, I remember you didn't kill a Type III with them last time, just one more level, as for being so nervous, it scared me to death." The second dog replied uncaringly.

"It's not what you think, Type IV and Type III are very different, I don't know how to tell you."

Su Bai didn't explain halfway through, and it was not appropriate to explain.

Sure enough, Su Bai didn't answer Ergouzi's words for a long time, and the perspective switched to the other side, and a middle-aged female reporter replied with a trembling voice.

"I'm sorry to tell you that the xenomorphs of this attack are mixed with this flying type II xenomorph black crowmon, and there are a lot of them!"

After saying that, she will look at the lizard sky!

I saw that the sky was black and oppressive, and there were crows everywhere.

The outermost anti-aircraft fire system of the Steel City has been deployed at this time!

And the air force is also dispatched to fight!

The whole sky is like fireworks, and you can see fighter jets and xenomorph stumps falling from time to time!

Zou Kai stood at the top, his fist clenching his hand gurgling.

At this time, a black crow beast pounced from high in the sky, Zou Kai suddenly pulled out a sharp alloy blade, turned around and directly split the black crow beast in half with a sword, and the black blood splattered on his body.

The adjutant next to him was also stunned, and they all surrounded him to protect Zou Kai.

Zou Kai raised his hand to stop the adjutant on the side, and looked into the distance with awe-inspiring eyes, what he cared about the most was actually the upcoming Type IV xenomorph, what kind of breed it would be, and what form it would take, these were very critical and deadly.
