The start of science and technology

"Where?" The headquarters, everyone looked to the monitoring screen.

I saw a huge variant organism in the northwest direction of the second defense line.

Its appearance and all known creatures, variant creatures are different, and its volume is comparable to a five-layer building, full of full body, can grasp the tentacle.

Its back, cracking a huge crack, full of gentle teeth!

It does not have an eye, the front of the nose, the front is a snail, which does not need to touch the entity, and can detect the terrain by ultrasonic waves, and other variants can be transmitted.

Its body surface is filled with mucus to form a layer of protective film. Like Du Xingyu, in the previous world, the sea-civilian battles, such biological protective film, can also resist the injury of explosion and laser.

Countless shells, machine guns and even missiles, they have not stopped the pace of it.

And the five-level variant is moving forward, and the body's touch is grasped on the ground, throw it into the big mouth of his back, and can chew it within a few small teeth in seconds, and then being acid The fluid digestion.

At the same time, its head will appear a hole, such as the gun tube, generally spray the spherical object wrapped in the biofilm.

When these spherical objects are played on military equipment, they immediately broke, and the acid fluid inside was exploded.

This kind of strong acid can almost corrode everything, and the armored vehicles made by alloy will also dissolve into a bunch of metals and biological acid mixed liquids within ten seconds!

If a person is stained, it will be killed in an instant!

"This monster, it's too horrible! Ignore our attack, I can also launch a biochemical bomb attack us!" The commander is very shocking, is this a five-level variant? Actually, you can drive on the battlefield on the battlefield!

Nothing can stop it, it is almost sweeping everything! Those who have been killed by humans have become its energy source, but also its ammunition library!

"It is no wonder that the beast is waiting for so long to attack, it turned out to wait for such a killing!" Li Taike is shocked, "if it makes it breaks through the defense line, Yunzhou Base is not guaranteed!"

"Gathering the firepower, be sure to stop it! Emit a white phosphorus bomb, put the mutant body on the ground!"

He is clearly realized that if the body of the mutant is not applied, this five-level variant can restore itself and attack.

The defensive line immediately concentrates the fire, blocks the advancement of the five-level variants, but the effect is small. This guy's mucus biological protective film seems to be high temperature.

Du Xingyu is a biochemical expert to begin research on this five-level variants.

"According to its current performance, it is called a battlefield spray." Du Xingyu took a name and said: "The defense ability of the battlefield sprayers is unquestionable. Now it is observed that it is the strongest weapon is a biological. Acid solution. "

"The flame encounters the acid solution, which will evaporate it into corrosive highly toxic steam, and the effects of variants are not affected, but will affect our own combat."

"I think the ideal attack method has two kinds. One is a biochemical weapon attack. The second is to send the bomb to its mouth and directly blow it from the interior!"

"Professor Du, the biochemical weapon should be at least an hour. I can only use the second way!" A military expert said.

"Well." Du Xingyu nodded and said: "There are more than 100 predators left here, just as a bait."

Before he brought one thousand predators, the light into the insect nest, decreased by nine hundred.

In the rear, Du Xingyu immediately started operating.

He broke ten predator's stomach, installing the high-explosive bomb, then stitching.

These "biochemical bombs" were put into battlefields, and they were disguised as a beasts, and stealing near the battlefield sprout.

In the defense line, the battlefield sprayers are still moving.

"Our laser weapon, destroyed!" The front line, the soldiers were still fighting, but the stress of the battlefield gave them too big! "

This monster who can't play and kill, it is simply a nightmare!

"This will go, there will be a gap or later!" The soldiers can't worry.

Unlike the combat of the variants and the war of human beings, once the fire is broken, a lot of variants are influence, that is not the battle!

Mutual body is far more flexible, and at that time, it will be defeated!

"Continue to bomb!"

On the high wall, the automated shells are kept hit.

That five-level variants have noticed it, it swallows a bone giant body into the big mouth, and made dozens of acid-liquid bomb projected.

"Shu ..." The acid solution is usually ly on the turret, and the turret is corroded out of a big hole, and the shells that have not yet emitted out of the project, the turret is destroyed!

"Request support!"

"We can't hurry!"

"The five-level variant is about to break through the defense!"

"In the five minutes, the biochemical bomb is close to it!" In the communication channel, the commander shouted.

"Missile is aimed!" In the base, the missile launcher has aimed at five-level variants, waiting for the arrival of offensive moments.

The predators who have installed high-explosive bombs in vivo have been close to the battlefield spray, they rushed to the human position with the battlefield spray, and disguised into a member of the beast.

"Biological computer self-destruction procedure started!" Du Xingyu destroyed their biochemical brain so that predator will die on the spot.

Two predators died next to the battlefield sprayers, it didn't realize that this is a biochemical weapon manufactured by human beings.

Several tentacles have sent their bodies into their mouths and chew digestion.

"Booming!" The high-explosive bomb exploded in its body, exploding countless visceral debris and acid solution.

"Zi ..." The battlefield splitter began dramatic convulsions. Sure enough, the bomb from the internal detonated bomb has caused great harm to it.

But this is not enough to fatal!

"Missile launch!"

At the same time, the five missiles are positioned by radar, and the battlefield sprayers are subjective.

At this time, it is still in a serious injury, and there is no ability to defend so many missiles.

"Collapse!" The battlefield came from the battlefield, the black smoke was filled, and the whole line of defense was cleared.

And the five-level variant battlefield spray, has been fried four-point fifth! Death can't die again!

"Killing it!"

"Brothers, do it!"

"The aid of the soldiers, hurry to repair the defense line!"

"Continue to attack!" The soldiers shouted, see this variant was killed, they re-ignited the fight.

"I finally killed!" Li Taili and others loosened, "In order to kill it, we used weapons, enough to destroy an armored troops!"

"I haven't finished yet!" Du Xingyu's expression is still cautious.

"What's wrong?" Everyone looked at him.

"The five-level variability cannot only be only one!" Du Xingyu manipulated the computer, transferred to a specific picture, said, "You see!"

Everyone is going to see, I saw the three battlefield sprouts in the rear of the beast!

In addition to the battlefield spray, five-level variants have also occurred on the sky.

That is a huge bird that has never seen anything, or it is called Fei Long!

Its wings show for tens of meters, a huge head and a long tail.

Under the attack of the fighter and the air defense system, it can still avoid it and defense, and easily destroy the fighter!

The most terrible thing is that it also has a biochemical weapon. It is a kind of destructive second sound wave, which can penetrate the defense equipment, directly destroy the five organs of the fighter driver!

Some fighter drivers who have been avoided directly in the cockpit directly, and the fighter also crashed!

On the inside of the second layer, there is a sudden concrete floor cracking, and there is no head, such as a giant groundworm that is the same as the cattle, it hits a turret. The soldiers have not come yet and defense, and it has been drilled into the ground to disappear.

"So many five-level variants! There is also a beast!" The commanders face the face, this is, how to play? "

"I can only wait!" Du Xingyu understands that it is difficult to reverse the situation.

"Is it necessary to use nuclear weapons? But the variants have invaded to the inside, launch nuclear weapons, most of the Yunzhou base will be destroyed."

In the clouds under the Yunzhou base, there is a nuclear impact, and it can be considered these refuge, and it is not absolutely defending the nuclear weapons.

"How long is the biochemical weapon?" Du Xingyu contigures the transportation officer.

"There is still half an hour!" The transportation tube replied.

"Half an hour." Du Xingyu said, "The second floor defense continues to stick, including the third line of defense, really can't, even refund to the base city!"

"Let the variants rushed into the city, lane fight?" Li Tai asked, human and variant hitting a city street fight, almost a must!

"That is the worst situation." Du Xingyu said, "You, you continue to command, I want to study the new five-level variants of these two."

He continues to collect information and analyze.

The battlefield sprayers can use the old way to attack it, and the five-level variants on the sky, Du Xingyu gives it a "sound wave wing", which is that it can transmit the audio wave.

Moreover, because it can pass the sound wave detection, only the supersonic level weapon can play it.

"Use laser weapons! The speed of the laser is absolutely hid, use the unmanned fighter to lure, then the laser attack!" Du Xingyu is in the past.

The five-level variant that appeared in the bottom floor, Du Xingyu said it is "the stock". It has not yet shown its biochemical weapon function, but from the bottom attack, it is definitely a point in human beings.

And it will bring the threat of life in the general people in the ground, must have it!

When I was thinking in Du Xingyu, the sneak destroyed several turrets.

"Well? This guy seems to be very keen to the thermal energy?" Du Xingyu noted a detail, and the status of the laden did not have the field of view, nor did it transmit the audio wave. Its perception should be a kind of thermal energy perception. If you use high thermal energy, you should attract it.
