Technology's opening live broadcast to build rockets

"Where?" In the headquarters, everyone looked at the surveillance screen.

I saw a huge mutant creature appearing in the northwest of the second line of defense.

Its appearance is different from all known creatures and mutant creatures. Its size is comparable to a five-story building, and its whole body is covered with tentacles that can wriggle and grab.

A huge crack opened on its back, filled with sharp teeth!

It has no organs such as eyes and nose. The front part is like a snail-like tentacles. These tentacles can detect the terrain through ultrasonic waves without touching the entity, and can also emit infrasound waves to command other mutants.

Its body surface is covered with mucus, forming a protective film. Like the gel protective film on the sea civilization battleship that Du Xingyu saw in the previous world, this biological protective film can also withstand damage from explosions and lasers.

Countless artillery shells, machine guns and even missiles were aimed at it, but failed to stop its progress.

As this fifth-level mutant moves forward, the tentacles on its body grab the mutant corpse on the ground and throw it into the large mouth on its back. The tens of thousands of tiny teeth inside can chew it up in seconds, and then it is eaten by acid. liquid digestion.

At the same time, a hole will appear in its head, and it will spray spherical objects wrapped in biofilm toward the sergeant facilities on the defense line like a cannon barrel.

When these spherical objects hit military equipment, they immediately burst and the acid inside exploded.

This strong acid can corrode almost everything. Even armored vehicles made of alloys will dissolve into a pile of metal and biological strong acid mixture within ten seconds!

If a person gets a little bit of it, he will die instantly!

"This monster is so terrifying! It ignores our attacks and can still launch biological and chemical bombs to attack us!" The commanders were extremely shocked. Is this a level five mutant? He can actually advance on the battlefield with lasers and bombs!

Nothing can stop it, it sweeps through almost everything! And those mutants killed by humans have become its energy source and its ammunition depot!

"No wonder the monster wave waited so long to attack. It turned out to be waiting for such a big killer!" Li Tai said in horror, "If it is allowed to break through the defense line, the Yunzhou base will not be protected!"

"Gather your firepower and be sure to stop it! Launch white phosphorus bombs to burn all the mutant corpses on the ground!"

He clearly realized that if the mutant's body was not removed, the fifth-level mutant would be able to continuously repair itself and attack.

The defensive line immediately concentrated its firepower to block the advance of the fifth-level mutants, but with little success. This guy's slime biological protective film also seems to be able to withstand high temperatures.

Du Xingyu and biochemistry experts immediately began research on this fifth-level mutant.

"Based on its current performance, let's call it the battlefield sprayer." Du Xingyu gave it a name casually and said: "There is no doubt about the defensive ability of the battlefield sprayer. Now it is observed that its strongest weapon is the biological Acid.”

"When flame encounters acid, it will evaporate into corrosive and highly toxic vapor. The mutant will not have much impact, but will affect our own operations."

"I think there are two ideal attack methods. One is a biological and chemical weapon attack, and the second is to send a bomb to its mouth and blow it up directly from the inside!"

"Professor Du, it will take at least another hour for the biological and chemical weapons to arrive. We can only use the second method!" said a military expert.

"Yes." Du Xingyu nodded and said, "We have more than a hundred predators left here, which can be used as bait."

The thousand predators he brought before were reduced to nine hundred just by entering the insect nest to gather information.

At the rear, Du Xingyu immediately asked people to start operations.

He ripped open the bellies of ten Predators, loaded them with high-explosive bombs, and then sewed them back together.

These "biochemical bombs" are thrown into the battlefield, disguised as members of the beast tide, and sneak up on the battlefield sprayers.

At the defense line, the battlefield sprayers are still advancing.

"Our laser weapons have been destroyed!" On the front line, the soldiers were still fighting, but the pressure from the battlefield sprayers was too much!

This monster that cannot be beaten or killed is simply a nightmare!

"If this continues, sooner or later there will be a gap here!" The soldiers were anxious.

The battle against mutants is different from the war against humans. Once there is a hole in the defense line and a large number of mutants pour in, it will not be as simple as a battle!

The mutants are far more flexible than them, and they will be completely defeated by then!

"Keep bombing!"

On the high wall, automated artillery shells were constantly bombarding.

The fifth-level mutant had noticed it, and it swallowed the body of a giant bone-armored elephant into its mouth, making dozens of acid bombs and projecting them out.

"Hiss..." The acid rained down on the turret, and a big hole was immediately corroded into the turret. The unfired shells exploded on the spot, and the turret was destroyed!

"Request support!"

"We can't hold it anymore!"

"The fifth-level mutant is about to break through the defense line!"

"Hold on for five more minutes, the biological and chemical bomb is already close to it!" the commander shouted on the communication channel.

"Missile aiming!" In the base, the missile launch pad has been aimed at the fifth-level mutant, waiting for the moment of attack.

The predators with high-explosive bombs installed in their bodies have already approached the battlefield sprayers. They rush towards the human positions with the battlefield sprayers, disguised as members of the beast tide.

"The biological computer self-destruct program is activated!" Du Xingyu destroyed their biochemical brains remotely, so that the predators would be brain-dead on the spot.

Two predators died next to the battlefield sprayer, unaware that it was a biological weapon made by humans.

Several tentacles carried their corpses into the mouth for chewing and digestion.

"Boom!" The high-explosive bomb exploded inside its body, exploding countless internal organ fragments and acid.

"Ah..." The battlefield sprayer began to twitch violently. Sure enough, the bomb detonated from the inside caused great damage to it.

But it's not fatal!

"Missile launch!"

At the same time, five missiles were located by radar and aimed at the battlefield sprayers.

At this time, it was still seriously injured and had no ability to defend against so many missiles.

"Collapse!" There was a sound like the sky was shattering and the earth was shattering, black smoke filled the air, and an open space was cleared in front of the entire defense line.

The fifth-level mutant battlefield sprayer has been blown to pieces! You can't die any more!

"Blow it up!"

"Brothers, let's do it!"

"Reinforcements have arrived, hurry up and repair the defense line!"

"Continue to attack!" the soldiers shouted. Seeing that the mutant was killed, they rekindled their fighting spirit.

"It was finally killed!" Li Tai and others breathed a sigh of relief, "To kill it, the weapons we used were enough to destroy an armored force!"

"It's not over yet!" Du Xingyu's expression remained cautious.

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

"There can't be only one level five mutant!" Du Xingyu controlled the computer, adjusted to a specific screen, and said, "Look!"

Everyone looked intently and saw three more battlefield sprayers appearing behind the beast tide!

In addition to battlefield sprayers, level five mutants also appeared in the sky.

It was a huge bird that humans had never seen before, or it wouldn't be an exaggeration to call it a flying dragon!

Its wingspan is tens of meters long, with a huge head and a long tail.

It can continue to dodge and defend under attacks from fighter jets and anti-aircraft defense systems, easily destroying fighter jets!

The most terrifying thing is that it also possesses biological and chemical weapons. The chirp it emits is an extremely destructive infrasound wave that can penetrate defensive equipment and directly destroy the internal organs of the fighter pilot!

Some fighter pilots who were unable to escape died suddenly in the cockpit, and the fighter jets also crashed!

On the ground inside the second layer of defense, the concrete ground suddenly cracked, and a giant underground worm with no head, like a cow's intestines came out, and it hit a turret with its head. Before the soldiers could defend themselves, it disappeared into the ground again.

"So many level five mutants! There is also a tide of beasts!" The commanders' faces turned pale. How should we fight this battle?

"We can only wait!" Du Xingyu understood that it was difficult to reverse the situation with thermal weapons.

"Are we going to use nuclear weapons? But the mutants have invaded the inside and launched nuclear weapons. Most of the entire Yunzhou base will be destroyed."

There are nuclear shelters built under the Yunzhou base, but even these shelters cannot absolutely defend against nuclear weapons.

"How long will the biological and chemical weapons last?" Du Xingyu contacted the transportation officer.

"There's still half an hour!" the transport pipe replied.

"Half an hour." Du Xingyu said, "Continue to hold on to the second layer of defense, including the third layer of defense. If it doesn't work, you can even retreat to the base city!"

"Let the mutants rush into the city and fight in the streets?" Li Tai asked. Humans and mutants are almost bound to lose in urban street fights!

"That's the worst case scenario." Du Xingyu said, "Everyone, you continue to command, I want to study these two new level five mutants."

He continued to collect information and analyze it.

The battlefield sprayers can use the old method to sneak attack it, and the fifth-level mutant in the sky, Du Xingyu named it "Sonic Pterosaur", its characteristic is that it can emit infrasound waves.

And because it can detect through sound waves, only supersonic weapons can hit it.

"Use laser weapons! The sonic pterosaur can't dodge at the speed of lasers. Use unmanned fighter planes to lure them, and then attack them with lasers!" Du Xingyu sent a message.

The fifth-level mutant that appeared underground on the other side was called "Stalker" by Du Xingyu. It has not yet demonstrated its biological and chemical weapon functions, but an attack from the underground is definitely something that humans will find difficult to deal with.

Moreover, it will pose a life threat to the ordinary people in the underground shelter, so it must be killed!

While Du Xingyu was thinking, the stalkers destroyed several more turrets.

"Huh? This guy seems to be very sensitive to heat energy?" Du Xingyu noticed a detail. The stalker has no ground field of vision and does not emit infrasound waves. Its perception should be a type of thermal energy perception. If you use something with high thermal energy, you should be able to attract its attention.
