I became a witch, but I started the industrial revolution

High temperature really is a special killer for all carbon-based organisms. If they are not killed, the only possibility is that the temperature is not high enough.

As an area was cleared, Betty and the others had a place to stay. They fired their PKDMs equipped with high-explosive bullets at the tentacles that were nearby and blew them into pieces. At the same time, the entire team quickly advanced into the industrial area.

They would definitely not be able to survive such a dense array of tentacles in an open area, but entering the building complex would at least ensure that they would not be attacked from all sides.

However, as the black carpet went deeper, its attack became more and more fierce and rapid. When it saw that the tentacles were not effective, the black carpet a thousand meters away began to swell up with purple gelatinous pustules 0.5-1 meter high.

When Betty and the others exploded the tentacles around them one by one, a large number of black, multi-legged monsters similar to spiders rushed out from the broken pustules, and their white compound eyes all looked at the team. The number of them was more than the total number of monster groups they had encountered before.

The multi-legged monsters pushed each other to form a three-meter-high monster wall, and collided head-on with the continuously spraying gasoline. The high temperature of more than 1500° made it difficult for the monster tide to break through, but the speed of fuel consumption in the tank also made Betty, who was listening to the flamethrower's report, anxious:

"Everyone! Prepare the rockets. Deploy 200% of the rockets within 25 yards ahead to block the enemy. We must break out!"

'Swoosh, swoosh, swoosh...'

As dense smoke and whistling sounds came out of the rocket launcher mounted on the shoulder of the mecha, the bombing range in front was suddenly covered by dense explosions, and the endless tide of monsters also showed a clear interruption.

Seizing this opportunity, the team advanced more than two hundred meters forward, and were less than fifty meters away from the nearest factory area. However, they were once again nailed to the spot by the endless tide of monsters and could not move any closer.

Just as Betty was about to organize a second round of rocket bombing, Nia, who had been protected in the center of the team, suddenly said: "I can make the monsters no longer a threat to us, but it should only last for 1.2 minutes..."

Betty glanced in Nia's direction: "If you can really do it, one minute will be enough."

She didn't know much about Nia's specific information. She was temporarily transferred to their team at the beginning. She couldn't find any information except her own ability. She only said that she didn't have enough authority.

But the fact that she couldn't find anything was telling, so she didn't dwell on it too much.

'Um...'

Then Nia closed her eyes, her feet floated off the ground, and an invisible wave spread in all directions.

The area swept by the wave, and the tide of monsters that were still attacking madly collapsed instantly like a castle built of mud and sand being swept by the waves. All the multi-legged monsters fell to the ground and did not move.

Seeing this, everyone who was mentally prepared immediately started running towards the factory area for their lives. Nia's impact range was about 50 yards. Monsters beyond this distance were not affected, but as long as they rushed into this distance, they would lose control directly.

No one knows how Nia did it, but it doesn't seem to matter.

[Ding! Intruder! ]

As soon as everyone rushed into the factory, a cold synthesized voice rang out inside the factory, accompanied by a sound of mechanical transmission, causing everyone to subconsciously raise their weapons and be on guard.

【Didi...Entry permission approved. 】

Everyone looked in the direction of the sound, and saw a translucent tracked mecha slowly appearing less than 10 meters away from them. If Medea were there, she would blurt out "tracked robot".

But for Betty and others, they have never seen such a thing as a robot, but it is not wrong to call it a tracked mecha.

The robot is about four meters tall, with a somewhat round upper body and no head. Instead, the front is covered with a whole piece of thick armor. Two pairs of cameras emitting red light can be seen through the glass holes on the armor.

There are two multi-barreled Vulcan cannons mounted on both sides of the rounded body, and two holes that are suspected to be gun barrels are vertically placed in the middle of the body. The chassis uses four segmented tracks as movement support, which makes it look like it is not easy to mess with.

Betty and the others couldn't hear what the robot just said, so they were on guard.

However, the opponent did not make any move, and even the weapons he had raised were all pointed at the ground, clearly indicating that he had no intention of attacking.

Why didn't it attack them?

An expert in the crowd turned around and looked back at the gate, then reminded Betty.

The screen next to the door showed a photo taken when they came in. Next to the photo was a scanning perspective image that showed them from inside to outside. There was also a green logo and text next to it.

Although they couldn't understand it, they could now roughly understand the language of this world civilization. It said that the certification was passed, but they had no idea what specifically allowed them to pass the certification.

"Ding! Intruder!"

The robot that had been quietly standing in place before was activated again. At the same time, Betty and others also heard the violent noise caused by the movement of the strange tide outside.

Nia's face turned pale: "I can't control it."

When everyone was ready to fight back, the robot had already moved to the factory door and began to attack the group of monsters rushing in from outside.

With a buzzing sound, countless dense bullets rushed towards the group of monsters, and in an instant, the monster tide that had just been overwhelming was shattered into pieces.

No fire, no sound

There was only the dense, rattling sound like a rainstorm when the monster was hit. Those with good eyesight could even see the monster flying in the air and breaking into countless tiny pieces that fell to the ground.

From the perspective of Betty and others, the opponent's external six-barreled Vulcan cannon-style gun looked like a fake. The barrels did not rotate, but the six barrels fired projectiles at the same time, and the firing speed of the projectiles was so fast that they were almost connected.

Obviously, this weapon is very different from the gunpowder kinetic energy-driven guns in their hands.

The robot completed the cleanup in just a few moves, and the monsters outside seemed to know that they could not afford to offend, and after this round of attack was defeated, they no longer made any moves.

While they were standing there in a daze, the other party had already moved back and stopped in front of a device in the factory. The armor on the back opened to reveal a matrix of neatly arranged boxes inside.

Four boxes were pushed into the corridor in front of the device. At the same time, the device extended a robotic arm to stuff four new rectangular boxes back into the vacant box positions. The robot lowered the baffle and returned to the position where it had stood at the beginning and continued to stare blankly.

One of the electrical engineers said tentatively: "Is this... an electromagnetic weapon?"

Chapter 380 Carry it back

The corridor seemed to be timed, and the rectangular boxes removed by the robot were not immediately put back into the machine. A young engineer came to the equipment and picked up one of the boxes for careful inspection.

The space inside the box is grid-like, a bit like honeycomb briquettes but with tighter spacing.

When he turned over, something inside slid out naturally due to gravity and fell into the palm of his mecha's big hand. They were spheres the size of green beans.

If the robot uses electromagnetic weapons, then these spheres should be used as bullets, and this box is the magazine.

In the alliance, electromagnetic weapons are still in the theoretical verification stage. Compared with electromagnetic weapons, they are more inclined to try to use magic to launch projectiles, because this technology has been verified in actual combat on the air defense weapons of the multinational alliance.

The main problems that made them give up were the difficulty in enhancing the magnetic field and the limitation of battery power supply, but the thing in the robot's hand seemed to have solved these problems.

They have just witnessed the power. After solving the energy supply problem, the advantage of electromagnetic weapons' firing frequency of thousands of rounds per minute was brought into play.

There is no barrel overheating, no high pressure in the chamber, and no fatigue of metal components. In theory, as long as you have enough ammunition, its rate of fire can be maintained at thousands or even tens of thousands of rounds per minute under the premise that the electromagnetic power remains unchanged.

With such a high demand for ammunition, steel ball spheres are a more economical way to manufacture ammunition. They are also very efficient in loading. This kind of honeycomb matrix magazine can be loaded directly by pouring it from above, and the spheres will slide in along the grid by themselves.

The more the engineers looked at it, the brighter their eyes became. If they could learn this technology, their trip would not be in vain. Mecha warriors naturally have a need for this kind of weapon.

Smaller ammunition volume means larger ammunition loading capacity, and their current ammunition reserves are somewhat insufficient.

The gas kinetic energy weapons of the Alliance will be affected by gunpowder gas, causing various firearm failures. The complexity of firearms is essentially to cleverly utilize gas pressure kinetic energy in various ways, but this is the world. When you solve one problem, other problems will inevitably arise...

Electromagnetic weapons do not require any of these. As long as there is no problem with the magnetic field binding, its excitation method is the simplest. With less work and fewer mistakes, the failure rate will naturally be reduced to the lowest.

As he was thinking, he turned to look at the robot with some eagerness in his eyes, and then he was pulled away by his colleague.

Just kidding, although they had a good relationship, he didn't want to use a shovel to help his friend collect the body parts.

Nia looked at the two comrades with some curiosity: "What... were you trying to do just now?"

The young engineer did not hide his feelings and pointed at the robot and said, "I want to carry it back."

Nia's eyes sparkled: "It's a little difficult to control. If it's something else, I can help."

The young man was a little confused, "Others?"

Nia waved her hand and all the lights in the factory turned on one after another. In the center of the huge factory about a hundred meters away from them, a square formation of robots stood there quietly, like packaged goods.

Everyone: '...'

Betty: “…”

"It looks like this is a military factory, but why is it located outside the factory area? Moreover, it doesn't make sense that it would be destroyed if there are robots like this, right?"

Thinking about the scene just now where a single robot army defeated a group of monsters in an instant, they felt complicated, not to mention that there were at least a hundred robots parked here, and the monsters might not be enough for these machines to kill.

With the robot not turned on, a group of experts surrounded it and touched the robot all over.

Experts and scholars in the computer field also want to try to see if they can crack the opponent's chip and turn it into their own combat power.

If you can control a few robots as reinforcements, then the rest of the journey will be a lot of killing.

Betty did not participate, but looked at the robots that had been silently waiting and the cameras scattered around the factory thoughtfully.

Her curiosity about these robots was far less intense than her desire to know the truth.

She always felt that everything went so smoothly after their group broke into the factory that it was a bit weird. This factory obviously had its own certification procedures, but they were able to pass safely, while the monsters outside could not.

Is this industrial zone open to all humans? If these aliens are also counted as humans in this world, then there is obviously no difference in the physiological signs of the two sides.

But she always felt that the robot's warning about "invaders" was not groundless.

Perhaps the sentence at the beginning was the original intention of the robot guard, but not the one later, which means that there may still be living people in this world.

The computer expert struggled for a long time but couldn't find what to change. Finally, Nia couldn't stand it anymore and directly reached out and touched the processor of one of the standby robots. After a moment, blue light lit up in the robot's eyes.

expert:"..."

No, that makes me look stupid.

Seeing the other party's strange look, Nia smiled embarrassedly and said modestly: "If it weren't for your help, I wouldn't be able to control it so easily."

Um... I couldn't find its processor, so he helped me find it, which is a big help~

The way everyone looked at Nia was fairly normal, with a feeling that was both unexpected and reasonable.

Nia is a true psychic, which is recognized by many teachers and professors, because she has hardly received any spiritual magic guidance like other psychics, and grew up in a completely wild way.

Her abilities are different from the existing magic system, and are also very different from spiritual magic.

Her ability is closer to making her wishes come true. Whether it is control or attack, each ability that is materialized into reality changes with her thoughts.

For example, when Nia attacks a wooden stake, the two different ideas of destruction and annihilation in her mind will lead to very different ways of attacking the stake.

The former simply swung out an invisible mental whip to break the wooden stake, while the latter split the opponent into wood chips out of thin air.

As the energy output increases, she can even grind it into dust in the air. Even a metal ingot can be broken into particles by her.

Theoretically, it is easier for her to destroy a living thing. After all, how can flesh be stronger than metal?

However, during the experiment, Nia was always facing inanimate objects. When facing living things, Nia's kind and peaceful heart prevented her from crossing that threshold for the time being, and the experimenters did not force her, so the data in this regard is currently blank.

Chapter 381 Welcome back

It’s not that the experimenters were reasonable, but they were given a death order so that they didn’t dare force Nia to do something she didn’t want to do.

Nia couldn't control more robots, and she had to divide her attention to control the remaining aliens. The crowd didn't force her, and took the new robot and continued to go deeper.

It is probably impossible to reach the next area without the help of the train, so it is better to explore this factory area, perhaps you can get some unexpected gains.

At least their trip would not be in vain if they brought this electromagnetic robot back to the alliance. After completing the minimum mission objectives, the team atmosphere became a little calmer.
