City A, the headquarters of the Hero Association.

Five robots with the same round shape and eight tentacles have attacked the Hero Guild headquarters, and Gus is directing the escort team to stop the robot's attack, and there is no time to care.

Guth had already seen Genos's call for help, but he couldn't spare his hand.

"Give me a stronger garrison from the east!"

"Transfer the artillery team to the south entrance and exit for me, and you can't let the other side enter the headquarters!"

"The western portal is almost untenable, send me reinforcements!"

Gus arranges the fortifications while keeping an eye on the movements of the five robots.

Five 100-meter-high robots, divided into five directions, attacked the five portals of the headquarters.

The robot is huge, its eight claws are indestructible, and with laser weapons, even a fortress can be captured.

Because the headquarters was attacked by underground people before, the defense system has been strengthened, and it can still be supported for a while, but the hero headquarters lacks S-class heroes to garrison, and it is only a matter of time before it is breached.

"Contact the army for me and ask them to send fighter planes over!" Gus quickly recognized the situation and appealed to the army for help.

"Sir, the army is being attacked by robots at the same time, and there is no way to help for the time being!"

The men brought absolutely bad news for Gus.

"What else is available for reinforcements now!"

Gus's men were all silent, and now most of the S-class and A-class heroes were lying in the hospital, and the round robot was not a B-class and C-class hero to deal with, and the headquarters of the Hero Association was now isolated.

"Send me the Northern Thunder!" Gus can only do this, the Hero Association cannot be destroyed, otherwise humanity will lose its spiritual faith.

"Sir, we've already contacted the Northern Thunderbolt, but he said he's not available right now!"

"Someone in the hospital has been attacked!"

Gus was surprised: "What! Isn't even the Northern Thunderbolt an opponent of robots? ”

"I heard that there seem to be a lot of small robots in the robot's body, and it will take time for Beiying Lei and Genos to solve the little robots!"

Gus was even more surprised when he heard this: "Little robot?!"

Soon Gus saw the spider robots.

After the five circular robots attacked the headquarters for a long time, their bodies cracked a hole, and then dense spider robots poured onto the outer wall of the headquarters.

The spider robot is only the size of a palm, climbs along the outer wall of the headquarters, drills when it sees a gap, and even if there is no seam, they use a laser to make a crack.

Although the headquarters of the Hero Association has been reinforced, it cannot resist tens of thousands of laser openings, and soon small holes will be revealed in the outer wall of the headquarters, and spider robots will rush in.

As soon as Gus saw that the headquarters was full of loopholes, he didn't know it well.

Five circular robots, thirty claws kept waving, smashing into the outer wall of the headquarters, which was destroyed in the anthill, and the spider robot chiseled holes into the outer wall of the headquarters, so that the circular robots could easily break the outer wall of the headquarters.

Bang

Sure enough, the sturdy exterior wall of the headquarters collapsed after a series of blows from five robots, revealing a large hole.

The six claws of a circular robot turned into six drills, constantly expanding the hole, and a large number of spider robots followed the hole into the headquarters of the guild.

"Oh no, we can't let those spider bots enter the heart of the headquarters!" Gus screamed and quickly made a decision.

"Close all portals in the core and turn on the automatic weapon system!"

Hearing Gus's words, the people of the Hero Association turned pale, and cold sweat soon covered their foreheads.

Once the core of the headquarters is closed, although the invaders are turned away, there is no way for the people inside to escape.

Many people also know that the core has a self-destruct device, and Gus's plan is obvious, that is, when the last resort comes, he will be killed by the enemy.

Gus also seemed to see his men's concerns, but he still insisted on going his own way.

"What are you waiting for, don't forget, the oath you made when you became an employee of the Hero Society!"

Gus's words were like a slap in the face, and everyone was refreshed.

"I am willing to dedicate the rest of my life to protect the cause of mankind!"

"I am willing to dedicate the rest of my life to protect the cause of mankind!"

"I am willing to dedicate the rest of my life to protect the cause of mankind!"

When Gus heard the oath of his subordinates, he shouted excitedly: "Now is the time for your dedication, the headquarters of heroes can be destroyed, but it must not be destroyed in the hands of the enemy, we must leave the seeds of resistance for mankind!"

When the people of the Hero Association heard Gus's words, their eyes gradually became firm.

"Drop!"

An employee of the Hero Guild pressed the button to close the core, and all the portals lowered a one-foot-thick alloy gate.

When the spider robot came to the alloy gate, ten thousand lasers could not break through the gate, and the way forward was immediately blocked.

The circular robot then attacks the alloy gate with its giant tentacles.

Boom, boom, boom

The tentacle hit more than 10,000 tons, and although the alloy gate was strong, it couldn't stop it for long.

Every time the tentacles of the circular robot hit the door, the hearts of all the people in the Hero Guild fluttered once.

"Activate the self-detonation device!" Eventually, Gus gave the order to doom the same.

The hearts of the people of the Hero Association were tight, but they were still ready to follow the orders of their superiors, but just as they were about to activate the self-detonation device, the voice of the metal knight Bofoyi suddenly sounded in the speaker.

"I have a way to stop the robots outside, you guys stay away from the electronic devices first!"

Hearing Bofoyi's words, everyone was drenched in nectar and hurriedly gathered together to protect Gus in the middle, away from all electronic devices.

A blue pulse of electricity suddenly swept across the headquarters of the Hero Guild, and all the electronic devices that were swept by the pulse sparked electric sparks, and then scrapped in a puff of smoke.

The equipment that the Hero Guild had spent a lot of money on turned into a pile of scrap metal in Gus's excited eyes.

"It turned out to be an electromagnetic pulse!"

Electromagnetic pulse bombs use the energy generated by the explosion of explosives or the combustion of chemical fuels to convert them into high-power microwave radiation energy through microwave devices, and can emit pulsed microwave beams with peak power of more than a few megawatts and frequencies ranging from a few hundred hertz to several megahertz.

However, when an electronic product is swept by a pulse, a transient voltage of thousands of volts is rapidly generated on the circuit board, causing irreparable damage.

Although the Guild's equipment was scrapped, the robots were not spared, which was the reason for Gus's excitement.

I saw that whether it was a huge round robot or a large number of spider robots, after being swept by the pulse wave, all of them flashed and stood still.

The electromagnetic pulse covers an area of up to ten miles, and all electronic equipment is scrapped within ten miles, and the crisis of the Hero Association is temporarily alleviated.

In different cities, electromagnetic pulse bombs were dropped, and all the robots that were in danger of human survival stopped.

Also stopping are Genos and the Driving Knight, who are transformed humans and are also restrained by electromagnetic pulse bombs, but their core is still human, as long as they are properly treated afterwards, they will not have much impact.

At the moment when all the robots stopped, a rusty robot in the underground cave of G City moved. [.]
