All weapons were installed, and the crystal cannon was removed from the ship. The central control platform of the defense system is placed on the city wall, and Mo Yingxuan has set up a defensive formation here, and now he has to wait for the alien to come.

In order to facilitate cooperation, the Great Western Kingdom also arranged their headquarters together, but from their holographic map, many areas on Mars are blind spots.

"There's no way around it, our satellites were all destroyed by the alien waves, and the current monitoring map is still obtained by us constantly releasing reconnaissance vehicles, but it's also unstable, and the aliens know how to destroy them."

Yan Chengjian is indeed a military talent, and now the military power of the Great West Kingdom is equivalent to being in his hands.

Mo Yingxuan nodded, stimulating the tactical command platform in front of him, and a holographic image appeared in front of everyone.

This is a huge spherical shape, covering an area of hundreds of square kilometers, and the monitoring range involves the sky and underground, and the longest distance can detect more than 3,000 meters underground.

The image is completely realistic, the underground situation is clear, and the surrounding generals of the Great Western Kingdom breathe a sigh of relief when they see it, and they are finally relieved.

"Can we expand the scope even further? What if the alien attacks somewhere else? ”

Ling Doudou smiled: "No." The style of the aliens is all about killing, especially these traversal aliens.

They have no ability to reproduce, (1) (Ben) [Read] After the novel YBDU occupies new land, in addition to space travel, the fastest way to grow in strength is parasitism. ”

Zhang Binhui patted Yan Chengjian on the shoulder: "We are all targets of aliens. ”

The defense of the Imperial City was carried out in an orderly manner, with nine crystal cannons installed in the four most important positions, and a large number of laser cannons from the Great Western Kingdom were also placed on the city walls.

Since the war with the aliens, the Great Western Kingdom has also made many improvements in its defenses. They added anti-corrosion armor to all fortifications in the shortest possible time, and also injected high-strength cement into the ground in the fastest time.

Not only that, in order to prevent alien sneak attacks, Onishi also installed high-voltage electrodes underground, which also played a role in active defense to a certain extent.

On Mo Yingxuan's command platform, under the dense blue light points of the city defense, those are the treacherous mines that have been installed; The sky is also covered with blue light, these are invisible frost bullets;

And a larger-scale blue light point is arranged in the city defense, which is the Great Western Kingdom mecha that has been assembled, and the number of mobile artillery is comparable, and a revenge battle is about to begin.

In the command platform, the statistics on the right side are still zero, and the aliens did not appear as promised, and they changed their tactics.

Aliens are waiting.

The days go by quite long, and a Martian day is about the same as Earth's, and a little more. There are twenty-four hours and thirty-seven minutes in a day.

Until sunset, the sky was full of stars, and the alien had not yet appeared, and Yan Chengjian was a little anxious.

"Immortal envoy, the alien won't not come, right?"

Before Yan Chengjian's words fell, he heard an alarm of "beep", the command platform turned red, and the holographic map hanging in the air changed.

A large number of red spots of light emerged from the edge of the map, like a tide, and soon dyed the corners of the map bright red.

The Red Tide advanced extremely fast, and soon reached a range of five kilometers from the blue dot.

The stats on the right side of the map begin to change drastically, and the rate at which they rise is terrifying.

"Alien: Knife Worm; Direction: NW; Quantity: 312; Distribution: Ground: 161, Underground: 151......

We: special-shaped probe pile: 100; Trickery: 3100; Frost Bullet: 4300; Crystal Cannon: 9, 100% energy value ......"

"Alien: Knife Worm; Direction: NW; Quantity: 933; Distribution: Ground: 499, Underground: 434......

We: special-shaped probe pile: 100; Trickery: 3100; Frost Bullet: 4300; Crystal Cannon: 9, 100% energy value ......"

"Alien: Knife Worm; Direction: NW; Quantity: 1721; Distribution: Ground: 1001, Underground: 720......

We: special-shaped probe pile: 100; Trickery: 3100; Frost Bullet: 4300; Crystal Cannon: 9, 100% energy value ......"

………

The red pillar of light representing the number of aliens continued to rise, and it was not until 3936 stabilized that the location in the northwest direction of the holographic map had been dyed red.

When the soldiers of the Great Western Kingdom saw this statistics, they were all frightened:

"How is it possible, after more than half a month, their number has basically not decreased?"

The xenomorphs also seemed to notice the changes in the city's defenses, and the team stopped at a safe distance, and a large number of xenomorphs huddled together, densely packed like a large number of boulders piled up on the ground.

The "Simulated Moon" of the Great Western Kingdom floated to the northwest direction, shooting light into the alien camp, but soon a red light shot over, and all the "Simulated Moon" were destroyed, and the northwest direction was once again shrouded in darkness.

At the same time, the data statistics of the hologram changed again, and the red pillar of light representing the alien rose again.

"Alien: Knife Worm; Direction: NW; Quantity: 4428; Distribution: Ground: 1800, Air: 1428, Underground: 1200......

We: special-shaped probe pile: 100; Trickery: 3100; Frost Bullet: 4300; Crystal Cannon: 9, 100% energy value ......"

The noisy alien camp suddenly fell silent, the battlefield outside the imperial city instantly became silent, and even the light in the original sky dimmed, and everyone's heart hung in the air.

Ling Doudou slowly raised his right hand, Yan Cheng Jian Xin comprehended, and conveyed the order. The entire imperial city shook violently, the dust on the ground floated, and a low "buzz" spread throughout the mountains, and the mechs of the whole city were activated at the same time.

The neighing of the aliens was heard from the northwest, and they finally attacked.

In the holographic map, one of the pieces was separated from the sea of red, and rushed towards the imperial city in four directions, and a large tree blocking the middle of the road suddenly shook violently, and then made a "squeak" sound, slowly tilted to one side, and finally collapsed with a bang.

This time, the xenomorph is attacking from underground.

When the alien was two kilometers away from the defensive line, the treacherous mine activated.

At the foot of the imperial city, a few mud lines suddenly shot out, and the ground was like an earth dragon swimming, driving the ground mud layer to protrude, and straight towards the periphery.

After shooting more than a thousand meters, the earth dragon suddenly calmed down, but in the holographic map, the red tide separated from the red block suddenly became chaotic, and a large number of blue light spots tracked into the red tide as if they had eyes.

I heard a muffled sound of "boom" coming from the ground, and the ground was boiling like boiling water, and from time to time bubbles of earth bubbled.

Some of the aliens were closer to the ground, and they were chased and hit by the thunder, and the earth and stones were suddenly blasted into the sky like a fountain, and a large number of alien stumps were mixed in it, and the screams and screams were endless.
