Blue star road

The Steel City, a city made entirely of steel, stands majestically on the earth. A shrill alarm sounded over the entire city, and the streets had long been evacuated.

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

Although the culprit of the attack was a Type IV alien, according to the characteristics of the alien, there would definitely be a large number of low-level aliens following, and no one could guarantee whether there would be low-level aliens taking advantage of the gaps in the battle to break in.

Therefore, every time an attack is made, comprehensive defense is essential.

On the outskirts of the Steel City, a big man wearing black exoskeleton armor and with a tiger waist and bear back on the iron wall line shouted at the top of his voice!

"Come on, everyone, cheer up, and never allow any alien to cross the iron wall line. This is our pride! We will defend it at all costs with our blood!"

"Fight to the end!!!"

"Fight to the end!!!"

"Fight to the end!!!"

...

The soldiers on the entire iron wall line responded with hysterical roars, which was a kind of passion and honor as a soldier.

Not far away, a group of teams wearing gray exoskeleton armor watched all this coldly. They all had unique marks on their chests. They were the Swift Team of the G Department.

Although Wang Quan said that the Steel City did not need much support.

But the G Department teams stationed in the Steel City also moved, but the atmosphere seemed a bit out of place.

A team member asked the captain in a low voice.

"Captain Lu You, what is our mission this time?"

"Just assist in defense, the main force will be handed over to the combatants of the Steel City, and temporarily obey Zou Kai's command." Lu You (Captain of the Swift Team) looked at the big man.

(Zou Kai is 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 Steel City is still very different from other cities. The entire Steel City is a semi-militarized city with a tough folk style! 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 Iron City. Of course, this is not for nothing. Almost every descendant of the Zou family joined the army, but more than half of them died in the war defending the Iron City.

It was so in the past and it will be so in the future!

Of course, thanks to the big cities like Iron City and Dragon City, the small cities in the back can be peaceful.

In fact, in the early days, these key cities were all in the central part. It was only because Longxia Kingdom lost nearly half of its territory that the important main cities were exposed on the front line, which was really helpless.

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

Zou Kai did not feel Lu You's gaze at all at this time. Of course, even if he felt it, he would not care. He looked into the distance with a tense face!

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

Boom~

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

The whole earth has begun to shake violently!

"Get ready for the battle!!!" Zou Kai shouted while putting on the exoskeleton helmet.

"Yes! General!"

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

One after another, the black large-caliber self-propelled artillery extended out, the Vulcan G-03 heavy Green, 7MM caliber bullets, the firing rate can reach 12,000 bullets per minute at full speed.

Then a large number of gun muzzles and missile launchers were deployed.

At this time, countless dust rolled up in the distance!

In Zou Kai's eyes, the dust rolled up in the distance was full of red dots!

"Damn it!" He cursed in a low voice. It was obvious that the IV-type alien had incited its alien tide! The IQ was not ordinary high!

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

Zou Kai's eyes were fixed on the alien tide that was getting closer and closer!

Ten kilometers! Nine kilometers!

...

Three kilometers!

1000 meters! 800 meters!

Attack!!!

Boom~~~

The rain of bullets and shells fell into the alien tide instantly!

The explosion that resounded through the sky opened the curtain of war in the Steel City!

In the refuge area of ​​​​C3 District of Longcheng, Su Bai, Er Gouzi and others were almost staring straight at the screen, and saw that the image switched to the Steel City.

A middle-aged reporter stood on the iron wall defense line and spoke very professionally.

"This is the Iron Wall Defense Line of the Steel City. The tide of alien species has begun to impact the defense line. We can see that the battle is very fierce. The number of invading alien species is very large. It is temporarily impossible to count the number, but I believe that the Steel City is absolutely indestructible..."

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

Then the image spun around, accompanied by screams!

Su Bai and Er Gouzi were dumbfounded!

"What's the situation!" Er Gouzi asked puzzledly.

"If I'm not mistaken, it should be a Type II Black Crow Beast that took him away." Su Bai's eyes changed slightly.

"Type II? I see? I thought it was something else? By the way, what is the highest possible type of attack on the Steel City?" Er Gouzi asked after hearing what Su Bai said.

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

"Oh, then there's nothing to be afraid of. I remember that last time you and them also killed a Type III, it was just one more level. As for being so nervous, it scared me to death." Ergouzi didn't care. replied.

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

Su Bai stopped explaining in the middle of speaking, and it was not appropriate to explain.

Sure enough, not long after Su Bai answered Er Gouzi's words, the perspective switched to the other side, and a middle-aged female reporter reported back with a trembling voice.

"Unfortunately, I have to tell you that the flying type II mutant black crow beast was mixed into the mutants attacked this time, and there are a lot of them!"

After saying that, she turned the camera to the sky!

The sky was dark and there were black crow beasts everywhere.

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

And the air force also dispatched to fight!

The entire sky becomes dazzling like fireworks, and from time to time you can see fighter jets and alien limbs falling down!

Zou Kai stood at the top, his fist clenched.

At this time, a black crow beast jumped up from high altitude. Zou Kai suddenly pulled out the sharp alloy blade, turned around and slashed the black crow beast in half with a sword, and black blood spattered on its body.

The adjutants next to him were also startled and gathered around to protect Zou Kai.

Zou Kai raised his hand to stop the adjutant on the side and looked into the distance with a stern gaze. What he cared about most was actually the Type IV mutant that was about to attack. What kind of species would it be and what form would it take? These were all very crucial. and deadly.
