[The sad ...... of wanting to cry without tears, documents are not compatible, new computers are not usable, and computers are blind]

Time passed minute by minute, and the blood-red afterglow of the sunset began to splash on the Drow Mecha University, and the burst of red light was like a layer of red and black ghostly light, and the alien corpses killed by artillery fire were all over the narrow defensive cracks for hundreds of meters, layer upon layer, piled up.

The corpses were left behind by a very small number of xenomorphs, and many more corpses were reduced to ashes by the powerful artillery fire.

The red and black light reflected each other, and the hot air seemed to be frozen, presenting a tragic and tragic atmosphere.

suddenly

The xenomorph that was surging like a tide stopped attacking but did not leave, and began to hover in the air, and the sky that was already shrouded by the setting sun began to emit a dark light, which was the light emitted by the xenomorph's body, and darkness descended on the earth in advance.

This momentary pause caused the mech pilots to breathe a long sigh of relief.

The number of more than 200 mechs is not a lot, but because of the uninterrupted attacks of the aliens, there are more and more aliens that penetrate the defense, and there is less and less time to take turns to rest as at the beginning.

This kind of high-intensity combat is very painful for the students, who have never experienced actual combat, and they are fighting with all their blood.

Just as the entire Drow Mecha University was relaxed, a strange scene appeared in the sky.

In the distance, a team of xenomorphs that looked indistinguishable from the other xenomorphs flew at a gallop.

It's flying!

People are not mistaken, it is flying!

From people's understanding of aliens, aliens themselves are unable to fly in the atmosphere, they mainly rely on excellent bouncing ability to jump long distances, because of their changeable body, can maintain a long time in the air, and can change direction at will, so, this gives people a feeling of being able to fly.

No matter how far the jump is, it is an indisputable fact that the alien itself cannot fly in the air for a long time like a bird, and it must use other objects to form a reaction force to be able to jump over long distances.

Now, people see aliens that can fly, and these aliens seem to be fast, but in fact, they are much slower than other aliens, and it is this slowness that makes people realize that they are flying.

Flight!

The alien already has the ability to fly in the atmosphere!

Inexplicably, a trace of fear rose in the depths of people's hearts, for humans, aliens have the ability to fly is not a blessing for humans.

At this time, the flying alien team suddenly changed, and actually borrowed force from ordinary aliens, their borrowing methods are very simple, when ordinary aliens pass by, these aliens will suddenly conjure up tentacles with amazing elasticity when the aliens are close, forming a huge reaction force, and the aliens' bodies are immediately like a black lightning bolt charging towards the defense cracks, and at the same time, the ordinary aliens that have been galloping through the air layer upon layer swarming towards the narrow spatial cracks, A rolling Kuroshio tide was formed, drowning the alien that had borrowed its strength......

Why do they do it?

Is it to cover those aliens who can fly?

Fight!

Ben was in front of the defensive rift, and the students didn't have time to think, and the black alien torrent had already rolled over, like an impenetrable black locust.

The ferocity of this wave of attacks is beyond people's imagination, and the artillery fire of the automatic defense system can no longer be described by the light net, it is completely a light curtain built by the artillery fire, and the torrent is cut off in front of the light curtain, and countless aliens are turned into ashes by the light curtain.

There was a suffocating smell of burnt smell in the air, and the originally dark sky was also illuminated, and people could clearly see that the overwhelming aliens were like a huge black cauldron covering the entire Drow Mecha University, spreading for several kilometers, and the number was incalculable......

Soon, people understood why the alien formed such a huge attack, and as they guessed, the alien was covering, covering the more advanced alien penetration.

When this wave of attacks reached the fifth minute, an alien broke through, at first, people didn't pay attention to this alien, because, there were not hundreds of aliens that broke in, but dozens of them, and it was difficult for one or two aliens to make waves in Zall Mecha University, after all, now both students and refugees are caught in a frenzy of fighting.

This xenomorph proves with bloody facts that it is a mistake for people to take it lightly.

It bounces between mechs like lightning, drawing black lines one after another in the air, and that line makes people have a kind of amazement, a kind of intoxication, but it is the amazing and intoxicating lines that are like a high-frequency harvester harvesting crops, the only difference is that it is not harvesting crops, but life.

……

Liu Fei didn't know that the battle outside was so tragic, he was in a state of forgetting to sleep and eat, he didn't know how long time had passed, he had too much work to do, the complexity of the work was beyond his imagination, at the beginning, after building a few sets of models with the help of Xiao Qiangguang's brain, Liu Fei was still a little complacent, and soon, he found that the prototype and the actual construction were completely different things.

Some subtle optical links and delicate pipe network welding take a lot of time, often lying in one place for hours without moving.

However, the effort pays off, in this kind of wholehearted work, the unit of the warped space looks decent, some intricate optical path optical network is gradually straightened out, like a starry indicator light flashing in the quiet basement, the lifeless basement begins to glow with a breath of life.

Liu Fei's work was terminated at eight o'clock in the afternoon, and it was Xiao Qiangguang who forcibly pulled Liu Fei out of concentration.

"The rift in the defense can't hold up!"

Fei just nodded subconsciously, in fact, his brain was connecting the complex warped light rate panel, which was very delicate work and required concentration.

"Drow Mecha University is going to collapse!" Xiao Qiangguang yelled.

"Ah......h

Liu Fei jumped up like a spring.

"The multicolored xenomorph sent its direct descendants into the fight." Ben A is the most fast little bright light brain with a heavy face, losing the liveliness and eccentricity of the past.

"What direct descendants?" Liu Fei wondered.

"It is the offspring of the multicolored alien, theoretically, the alien is like a human being, knowledge cannot be inherited, and it needs to be learned in the process of growth, but the alien that has reached the level of the multicolored alien, the progeny can inherit a part of the evolutionary genes, that is to say, as long as it is the offspring of the multicolored alien, they are born with some extraordinary abilities, such as faster evolution, stronger attack power, in the past one hundred and sixty years, the multicolored alien has digested some characteristics of other species, For example, the ability to fly......"

"They've got the ability to fly?" Liu Fei's pupils constricted, this is not good news, the alien with the ability to fly has an absolute advantage in front of humans without high-tech weapons.

"Yes, however, their flight ability is not excellent, if they do not use their strength, they will not pose any threat to mecha and some high-tech weapons, and it may take a long evolutionary process to threaten the survival of human beings in terms of flight ability, but now, the threat posed to humans by the aliens that have penetrated into the defense system is imminent, and there are already some aliens who are trying to destroy the optoelectronic equipment of the defense system."

"They're in?" Liu Fei was taken aback.

"Yes, the students' combat effectiveness is too poor, you need to support them, otherwise, after twenty minutes, the defense system will be destroyed, and after thirty minutes, the entire Drow Mecha University will fall......"

Before Xiao Qiangguang's words were finished, Liu Fei's body had already turned into a wisp of green smoke and rushed towards the giant freight elevator.

Twenty minutes.

Twenty minutes of time!

……

The entire Drow Mecha University looked extremely tragic, the steel defense line composed of mecha had already suffered casualties, and a mecha was actually pierced through the cockpit by a alien, and the steel body weighing dozens of tons fell straight down like dry firewood.

This is the first mech to die so far.

For the first time, the students saw that the alien was able to destroy a steel fortress-like mecha, you know, the weight and size of the alien are about the same as that of humans, compared to the mecha, the weight of more than a hundred catties is simply insignificant, and it is this insignificant body that destroys a steel mecha weighing dozens of tons, which shakes the students' determination to defeat the alien.

When the first mecha fell to the ground, this casualty began to spread, and the mechs kept falling, and a large number of penetrating aliens rushed into the Drow Mecha University, and one by one the defense lines began to be exhausted, falling into a passive defensive state, and the strong combat power of the flying aliens disrupted people's positions.

The people who were enthusiastic about fighting seemed to have been poured cold water on them

Looking at the alien who chose the target to hunt in the sky, people lost confidence, and even the senior commentator who had been cheering up had a tragic atmosphere in his tone.

Just when people were desperate, suddenly, a familiar mecha appeared on the holographic screen, and this mecha had been missing for nearly two days.

――03, it's Xiaoqiang!

Inexplicably, people seem to have taken a shot in the arm, as if they can rely on Xiaoqiang's personal strength to reverse this decline.

"-03, it's Xiaoqiang!" The senior docent's voice trembled a little.

On the holographic screen, 03 wanted a sensitive giant beast to intersperse left and right in some mechas, flowing smoothly, without the slightest hindrance, the high-speed mechanical movement made people forget that it was a backward ancient mecha, what people saw was a giant mecha full of masculine beauty, up to fifteen meters high, the armor of the mecha flashed a metallic texture under the dazzling cannon fire, full of power......
