"Ready!"

"Electromagnetic cannon level 2 preparation!"

Then all the barrels began to be aimed in an unknown way. Pen ~ fun ~ pavilion www.biquge.info

"Ready!"

"Electromagnetic cannon level three preparation!"

Electric snakes began to swim around the barrels, and sparks began to burst out in all directions.

"Ready!"

"Launch!"

As soon as the words fell, metal rods weighing several kilograms were ejected at a speed invisible to the naked eye.

The principle of the electromagnetic cannon is not complicated, to put it bluntly, it is a linear motor that can be used to fire shells.

All countries and manufacturers that can produce elevator doors can make an "electromagnetic cannon", but it can catapult the "projectile" out of a few meters or hundreds of kilometers at one time.

The electromagnetic catapult of the aircraft carrier is also the application of electromagnetic force at the forefront of the weapon system, and the principle of electromagnetic catapult and electromagnetic cannon is also similar, and Huaxia and US imperialism.

It is recognized as the only two countries in the world that have developed an electromagnetic catapult for aircraft carriers. The electromagnetic catapult of the US imperialism has already been actually installed and tested on the aircraft carrier USS Ford.

And before the end of the world, there were also rumors: Huaxia had also installed an electromagnetic catapult in place in the land experimental base of an aircraft carrier in a certain city in a certain province, and had successfully catapulted and taken off the J-15 catapult version of the carrier-based aircraft.

It can be seen that Huaxia's electromagnetic catapult and electromagnetic cannon technology can be on a par with the United States imperialism, thanks to Huaxia's electromagnetic wizard Ma Mingwei.

Before the end of the world, there were several technical difficulties with the electromagnetic cannon:

The first is how to instantly excite a large power and high current.

The second is how to prevent the instantaneous high current from directly welding the shell into the barrel (if the insulation between the shell and the barrel is not done well, the ultra-high current electromagnetic gun will undoubtedly instantly become a super welding machine).

The first difficulty was solved after Wang Dong sent Li Yan's shy genius doctor to the research institute, and he used the energy conversion device he made to convert the biological energy in the crystal nucleus into electrical energy, so that a high-power current could be instantly stimulated.

And the second difficulty has also been improved after the end of the world, before the barrel and shells of the electromagnetic cannon were generally made of special metal, now you can add some zombies and evolution beasts to make materials, not only the strength is greatly increased, but also can achieve a certain degree of heat insulation.

However, because the research institute does not have the artifact-like smelting furnace of Wang Dong, and the time is too short, it is not very good in the application of materials, and with the current materials, it can only make a few disposable electromagnetic cannons that can kill sixth-level zombies.

Several special projectiles of electromagnetic cannons headed towards the three sixth-level zombies and the seventh-level zombie at an unimaginable speed, but it may be that the seventh-level zombies sensed the danger in advance and quickly hid behind the sixth-level defensive zombies.

"Boom, boom, boom!" There were four explosions in succession, and four projectiles hit a power zombie and a defensive zombie fiercely, and the power zombie was directly hit in the waist by one of the projectiles, and it was broken in two without even having time to react.

The other three projectiles hit the same defensive zombie, and the defense of the defensive zombie is much higher than that of the power zombie.

The first projectile only shattered the scale armor outside the zombie and lost its power, and the second and third projectiles tore the zombie that lost the scale armor defense.

And the military and Wang Dong only saw a rumbling sound, and a burst of dust and mist erupted on the ground to cover the seventh-level zombies, and after the dust and mist dissipated, whether it was the military or the evolutionary or Wang Dong, they all gasped.

The two torn sixth-level zombies were lying on the ground, already losing their combat effectiveness, but the seventh-level zombie was hiding behind the last sixth-level defensive zombie unharmed.

Wang Dong could clearly see a glimmer of wisdom flashing in the eyes of the seventh-level zombie, and then he hissed angrily in the sky, and suddenly the fourth-level zombies in the entire phalanx rushed towards this side.

And Wang Dong saw that the stomach of that special corrosive zombie was slowly squirming, thinking of the skill introduction he had just seen, and then shouted at Long Er and Commander Zhang: "Get out of the tank, it's dangerous!" ”

Immediately, Wang Dong didn't care whether Commander Zhang listened to him or not, turned around and ran away with the pet beast.

Commander Zhang and Long Er knew that Wang Dong would definitely not be alarmist at this moment, so they hurriedly got out of the car, but before they could give the order, the mouths of the dozens of corrosive zombies opened, and streams of dark green liquid sprayed out like sharp arrows.

The speed of this liquid jet is not very fast, plus most of the evolutionaries and soldiers reacted well, seeing this strange liquid, they didn't dare to touch it easily, and jumped backwards or to the side in time, but there were also a very small number of fourth-level evolutionaries who couldn't react, and they were directly drenched on their bodies by the strange liquid along with all the armored vehicles.

Multiply! Multiply! Multiply!

After the strange liquid was poured on the tanks and armored vehicles, there was a strange sizzling sound, and at the same time wisps of black smoke came out, this strange liquid turned out to be so corrosive that the steel body was corroded into large craters in just a few seconds.

After that, before the ordinary soldiers inside could escape, the entire armored vehicle turned into a large pinch of ashes in the air, and when the passing breeze blew it, the large pinch of ashes scattered in all directions, and it was too late to even scream.

And the fourth-level evolutionary who was directly poured on his body by that kind of liquid was more miserable, after all, the fourth-level strength was not low, and the energy in his body had a certain resistance to this corrosion.

However, this resistance did not save them, but only increased the pain, and their bodies were like melted butter, and in the terrible screams, the flesh and bones on their bodies all melted into a disgusting yellowish liquid.

"Help me! Help me! Yes!! ”

"Don't, ah!"

"Kill me!! Kill me! Yes!!! ”

...

In just half a minute, all the armored vehicles and more than a dozen fourth-level evolutionaries turned into black ash in the sky and more than a dozen puddles of pale yellow liquid left on the ground, coupled with the screams left in the air before death, which suddenly made this place look like Shura Hell.

The people who witnessed this scene couldn't help but weaken their legs. Secretly glad that he reacted in time, if he had been slow by half a beat, wouldn't he have been corroded into a puddle of liquid by now?!

Wang Dong thought that these fourth-level corrosive zombies were not so terrifying, but he never expected that the damage of this corrosive acid would be so great, and he felt that if a fifth-level evolutionary was corrupted by this fourth-level corrosive zombie, he would be seriously injured.
