Technological Empire of the City

Loading ammunition, shooting, and other actions were done in one go. The soldiers had trained countless times, but even so, the artillery attack only broke the tough skin of the bull, causing minor injuries.

"Hum~~".

Amidst the roar, the angry herd of bulls lowered their heads and rushed towards the huge unicorn against the huge unicorn.

"Boom boom boom boom". The sound of footsteps shook the sky, and the soldiers on the steel city wall panicked.

"Boom~".

"Boom~".

"---".

The bullet fired on the man bull was bounced off by the thick and tough skin, leaving only a white mark. It would not break the defense at all. The bullet that could break the defense was too late to launch an attack. The scene was very embarrassing for a while.

"Boom~".

"Boom~".

Like an army of wild bulls, they hit the steel city wall inconsistently, making a loud noise. The steel city wall shook a few times, and the interface between the city wall and the ground was cracked open, making a "click" sound. .

"Hum~~". The Barren Bulls turned their heads and let go of their bodies, allowing the Barren Bulls behind to have a space to rush over.

"Boom~ boom~ boom~".

The sound of the impact was endless, and the steel city wall began to shake violently. The soldiers standing above the city wall were unstable. Some soldiers screamed and fell from a height, fell into the barbaric cattle outside the city, and were trampled into meatloaf.

The pale-faced soldiers, holding on to something that could hold their bodies firmly, waited desperately for the arrival of death. Under the violent shaking, no one could fight back. Even the artillery on the steel city wall was shaken and the muzzle was moved. Bit up.

The non-commissioned officer leaned on the railing and shouted, "Fight back, artilleryman, press down the muzzle and open fire."

"It's shaking too much, I can't do it". The soldiers looked desperate.

Inside the steel city wall, all units were frightened by the shaking city wall, and even steel could be smashed like this. If you were hit by a bull, you would definitely be broken into pieces immediately, thinking of the auxiliary soldiers here, all their faces paled.

At the Institute of Biological Sciences, the old man Qiwen's pale hair trembled, and her lips trembled and said: "It's too strong, can this monster really be something we can deal with?"

The biologists were full of horror, but they were still analyzing Manniu's message.

"Skin is comparable to steel."

"The hardness of the unicorn has surpassed that of the alloy."

"The power reaches hundreds of tons."

"---".

The rocket launch base in the city, the non-commissioned officers received the order to counterattack, but hesitated, because if they attack now, because the target is too close to the city wall, it is very likely that they will accidentally injure the friendly army.

Thinking of this, the non-commissioned officer took the phone and reminded: "Please give the defenders a few more minutes, so that they can withdraw."

"Okay, three minutes, after three minutes, no matter what, shoot me." The phone fell silent for a moment, and then replied.

"Yes". The non-commissioned officer responded loudly, and quickly notified the soldiers guarding the city to retreat.

The three-minute evacuation time is very tight, and the city wall is shaking, and walking is very difficult. It is impossible to evacuate all the soldiers defending the city within three minutes. Thinking of this, the sergeant defending the city furiously said.

"Why is there only three minutes, three minutes can't withdraw at all, are we just being given up like this".

"If there are no bulls to bother you, and the wall will no longer move, can you withdraw within three minutes." Suddenly, a voice rang behind the sergeant, and the sergeant's face changed in fright, and he turned back sharply.

The sergeant breathed a sigh of relief when he saw the six members of Zhang Yue behind him. He almost drew his gun just now. Fortunately, he did not do so. In case of any misunderstanding, he could not bear it. After all, the Federation still needs the six members of Zhang Yue. Any misunderstanding is not allowed.

The non-commissioned officer nodded after analyzing it: "Yes, as long as the wall doesn't move anymore."

"Okay, let's resist Manniu, you only have three minutes to withdraw, remember." Zhang Yue said with a serious face that once three minutes arrive, Zhang Yue will not stay outside the city anyway.

"OK". The sergeant responded loudly.

"Let's go". Zhang Yue motioned to Xiaozhi and the five people beside him.

"Ok". The five Xiaozhi nodded and followed Zhang Yue from above the wall to jump directly outside the city.

"Boom~bang~bang~".

The six crisp sounds were covered by the loud noise of the bulls hitting the city wall, and the six Zhang Yue who descended outside the city were directly treated as enemies by thousands of bulls, and they rushed over directly. The indomitable momentum made people bear. Can't help but want to avoid it.

However, Zhang Yue's six people came down to prevent the bull from hitting the city wall, so they couldn't avoid it. Thinking of this, Zhang Yue shouted: "Let's get started."

"Good Le". The five Xiaozhi answered.

"Mental shock".

"Weng~".

Huge mental power radiated from Zhang Yue's brain. The huge body of the bulls does not mean that their mental power is very strong. When they are hit by the mental shock wave, their brains are in chaos. Fell to the ground softly.

"Boom~".

A large number of bulls rolled over and fell to the ground.

"Huh, it's up to you, hold on for two and a half minutes, and then we will withdraw." Zhang Yue, who burst out all his strength in an instant, panted heavily.

"good". The five Xiaozhi said with stern expressions.

The bulls whose spirits were shocked were dizzy and couldn't get up at all. Moreover, they fell to the ground and blocked their way so that the bulls further behind could not get close to the city wall, but this was only temporary.

After a minute or so, the dizzy bulls finally recovered their messy spirit, and reluctantly stood up, shaking their huge heads a few times, and the bulls ran wildly again.

"Lightning Storm".

"Boom." The loud noise of thunder flooded the city, and the white shining electric light pierced through the bodies of bulls one after another. The thunder and lightning jumped on the bulls, paralyzing the bulls that hit the city wall with their heads. Fell to the ground.

"Rumble rumbling." The barren cattle fell on the ground, throwing out the dust in the sky.

Although their skin is very tough and can resist bullets, lightning is an elemental attack that can invade the internal organs. After the internal organs are numbed with electricity, the bull has no choice but to wait for time to recover.

"Hum~~~". The barren cattle group further behind suddenly let out a cry of dissatisfaction, but the barbarous cattle group whose body was paralyzed by electricity couldn't get up at all.

Above the city wall, the no-swaying city wall allowed the soldiers to pass quickly and ran from the city wall to the city. They were almost there in the blink of an eye in three minutes. All the soldiers panted and withdrew from the city wall.

"Shoo~".

While the soldiers were worried, Zhang Yue and his group of six flew back from outside the city in the sky. Zhang Yue, who was pale, flew back with the six men in mental power, consuming the distance, and as soon as he landed, his body became weak. .

"Sister, are you all right". Xiaozhi quickly supported Zhang Yue and said with concern.

"I'm fine, just take a rest." Zhang Yue smiled and said.

"That's good, I will help you aside to rest, and we will leave the rest to them, and we will do everything that needs to be done." Xiaozhi suggested.

"OK~". Zhang Yue agreed.

Outside the city, the bull without interference, hit the city wall more violently. Inside the ten-centimeter-thick steel plate, there are stones such as sand and granite, which act as a buffer, but under constant impact, the steel plate cannot support it. Up.

"Boom~". The steel was smashed, and then sand and gravel overflowed, and soon, the steel plate outside the steel city wall was hit with hundreds of holes. The huge self-gravity caused the city wall to collapse and crooked to the direction outside the defense line.

"Rumble rumbling~". The collapsed city wall defensive line smashed one-third of the bulls, gravel soil and heavy steel plates, pressed against the closest bulls, killing a large number of bulls in an instant.

Blood oozes from the sand and gravel.

"Humhhhhh~". The death of their companions made the savage herds farther on the line of defense extremely angry. They roared and rushed forward, wanting their huge and incomparable feet to trample on all hostile targets.

But at the same time, on the federal side, the time for the rocket launcher had also arrived, and the non-commissioned officer roared calmly: "Launch."

As soon as the voice fell, thousands of rocket launchers lifted off with their tasted tail flames, and shrill voices resounded across the battlefield.

"Shoo~".

"Shoo~".

"---".

The rocket that flew to a high altitude fell in a parabolic shape, and the acceleration of the tail flame made the rocket's speed so fast, coupled with the acceleration of gravity, it fell on the head of the bull herd in an instant, and carried out a covering bombardment.

"Boom~".

"Boom~".

"---".

Amid the roar, the flames soared into the sky, and the battlefield was filled with smoke and dust. Under such fierce shelling, the remaining two-thirds of the barbaric herd suffered heavy casualties. Only the extremely lucky barbaric cows were able to make it. Survive.

But it was of no avail. The remaining bulls were not enough to threaten the Federation. The tracks of the chariot roared, and a volley of artillery shells shot out, slaughtering the remaining bulls, and blood stained the ground of the battlefield.

"We won, yeah".

"Great, we blocked the monster."

Cheers suddenly broke out, and the ecstatic soldiers and their companions hugged each other, sharing this joy.

The non-commissioned officers calmly ordered: "Be quiet, the engineers hurry up to repair the city wall. Remember to thicken the city wall so that it can't be knocked down so easily."

"Yes". The engineers responded and started the infrastructure work. All kinds of siege equipment were driven to the collapsed city wall, and the collapsed building materials were transported. Anything that could be used again was transported back to build a new city wall.

At the same time, in the Federal Institute of Biological Research, Dr. Qiwen's scientific research report was handed over here, and all the biologists panicked and handed the report to the top federal officials.

After seeing the content of the report, the head of the Federation changed his face dramatically and said: "No wonder so many monsters came in as soon as the passage was opened. It turned out that the aura of the seeds of civilization leaked out. Damn it, it must be a good thing that the scavenger's artificial intelligence did." .

"Then what to do, the breath has been exposed, even if the seeds of civilization are hidden, it won't help. Those monsters will still flood into our federation." The federal high-level suddenly exclaimed. ..
