The City of Steel, a city made of steel, stands magnificently on the earth. There are harsh alarms sounds over the entire city, and the streets have long been evacuated cleanly.

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

Although the culprit of the attack was the IV type xenophobia, according to the characteristics of the xenophobia, there will definitely be a large number of low-level xenophobia followed, and no one can guarantee whether there will be low-level xenophobia to break in through the gaps in the battle.

Therefore, every time you are attacked, full defense is essential.

On the outside of the Iron City, a man wearing black exoskeleton armor on the iron wall defense line shouted at the top of his throat!

"Everyone cheers me up. I will never allow any alien species to cross the iron wall defense line. 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 defense line responded with a hysterical roar, which was a kind of passion and glory as a soldier.

Not far away, a group of squads wearing gray exoskeleton armor looked at all this coldly, and they had unique marks on their chests, the swift team of G Department.

Although Wang Quankaikou Iron City does not need much support.

However, the G Department team stationed in the Iron City also started to move, but the atmosphere seemed a little out of place.

A team member whispered to the captain.

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

"Just assist in defense, the main force is handed over to the combatants of the Iron City, and temporarily obey Zou Kai's command." Lu You (captain of the Xunjie Squad) couldn't help but look at the big man.

(Zou Kai is the commander of the Second Army of the Iron City, and is a lieutenant general. He is responsible for guarding the Iron Wall Defense Line of the Iron City. His eldest brother is the Lord of the Iron City.)

The City of Steel is still very different from other cities. The City of Steel is a semi-military-managed city with strong folk customs here! Heavy industry is very developed, and the residents living here are basically proud of joining the army.

The Zou family has a very strong influence in the City of Steel. Of course, this was not for nothing. Almost every descendant of the Zou family joined the army, but more than half of the personnel were killed in the war to defend the City of Steel.

This is the case with the past and the future!

Of course, it is also thanks to large cities like Iron City and Longcheng that are in front and small cities behind are at peace. In fact, this is not the case. It is just because the Longxia Kingdom has actually fallen into nearly half of its territory, which has led to the important main city being exposed on the front line, which is really helpless.

Lu You seemed to have a very wise choice at this time, but in fact it was more of a helpless move. The stage here does not belong to them.

Zou Kai didn't feel Lu You's gaze at this time, and of course he wouldn't care even if he felt it. His tense face looked into the distance!

Although he was not unable to see the enemy, he could already feel the breath of death in the air.

Boom ~

There was a loud bang at the bottom of the wall of the sky, and a huge crack appeared instantly.

The whole earth has begun to shake violently!

"Prepare to fight!!!" Zou Kai shouted on his exoskeleton helmet.

"Yes! General!"

Suddenly, the soldiers on the iron wall defense line activated the fixed weapons on the defense line.

A series of black large-caliber self-propelled artillery extended out, Vulcan G-03 heavy Green, a 7mm caliber bullet with a fire rate of 12,000 bullets per minute when it is activated with all the best speed.

Then a large number of muzzles and missile launchers unfolded.

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

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

"Damn it!" He cursed in a low voice, it was obvious that the iv-type alien incited its alien tide! The IQ was not average!

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

Zou Kai's eyes were staring at the tide of alien species getting closer and closer!

Ten kilometers! Nine kilometers!

...

Three kilometers!

1000 meters! 800 meters!

attack!!!

Boom~~~

The rain of bullets in the sky instantly fell into the alien tide with the shells!

The explosion that resounded through the sky opened the curtain of war in the city of steel!

In the shelter area of ​​Longcheng C3, Su Bai, Ergouzi and others were almost looking straight, and they saw that the image switched to the Iron City.

A middle-aged journalist stood very dedicatedly on the iron wall defense line and preached.

"This is the Iron City and the Iron Wall Defense Line. The alien tide has begun to hit the defense line. We can see that the battle is very fierce. There are a lot of aliens attacking. The number cannot be counted for the time being, but I believe that the Iron City is absolutely invincible..."

Just before the reporter finished speaking, a black figure suddenly passed by on his head.

Then the image was spinning, accompanied by screams!

Su Bai and Ergouzi were both stunned!

"What's the situation!" Ergouzi asked in confusion.

"If I read it correctly, it should be a type ii black crow beast that took him away." Su Bai's eyes changed slightly.

"Type ii? So that's it? What did I think it was? By the way, in the attack on the Iron City this time, what type of type is likely to appear?" Ergouzi asked after hearing Su Bai's words.

"The fourth-level warning should be iv-type."

"Oh, then there's nothing to be afraid of. I remember that you and them also killed a type iii together last time, but it was just one level longer. As for being so nervous, I was scared to death." Ergouzi replied indifferently.

"It's not what you think. The iv and iii type are very different. Forget it, I don't know how to tell you."

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

Sure enough, Su Bai had just answered Ergouzi for a long time, and his perspective changed to the other side, and a middle-aged female reporter replied in a trembling voice.

"I'm very unfortunate to tell you that the alien species attacked this time were mixed with the type II alien black crow beasts in this flight system, and there were many!

After saying that, she put her vision to the sky!

I saw black crow beasts everywhere in the sky.

The outermost air defense firepower system of the City of Steel has been launched at this time!

And the air force also dispatched to fight!

The whole sky became dazzling like fireworks. From time to time, you can see fighter jets and alien limbs falling down!

Zou Kai stood at the highest point, his hand clenched with fists clattering.

At this time, a black crow beast rushed up from the sky. Zou Kai suddenly pulled out the sharp alloy blade, turned around and split the black crow beast in half with a sword, and black blood splattered on it.

The adjutants next to them were also stunned and surrounded them to protect Zou Kai.

Zou Kai raised his hand to stop the adjutant beside him and looked into the distance with awesome eyes. What he cares most about was actually the upcoming iv-type alien species. What kind of breed will it be and what form it will appear in. These are very critical and fatal.
