Zhati is a pure industrial city, almost all the ore smelting enterprises in Charanxing are located here, and most of the natural people who work and live here are the staff of various smelting enterprises, and more than the staff are artificial people responsible for all kinds of dangerous operations.

Because the number of natural persons is not particularly large, artificial humans do not break the law and commit crimes, and the places close to the ore smelting operation area are generally toxic and harmful, the number of police officers of the Public Security Bureau and the military of the Governor's Palace stationed in Zatai City is the smallest among the three cities.

As a result, when the alien entity invaded, the entire city was completely unable to resist, and the military, police, and citizens quickly died in large numbers.

After the network was cut off, there were no natural people to give orders to the androids, and in order to comply with the first principle of "protecting the company's property", the androids also collectively gave up resistance and fled the city, hiding in the wilderness where the monsters could not find and would not go to find them.

When the disaster is over, the company to which these androids belong will send people to recover their "property".

Yang Wuji walked around Zatai City, but found no survivors, not even a complete corpse, so he could only concentrate on chasing the traces of the monster.

He followed the traces of the invasion of the otherworldly entities, traced all the way backwards, and soon left the urban area of Zatai City.

Whether it is invading or retreating, the traces left by the monsters all point in one direction, that is, the west of Knoll City, which is also the direction where another city, Huanglong City, is located.

Unlike Zha Tai, Hoang Long is a city that specializes in the production and manufacture of various types of ore-related products.

The special ores smelted from Zatai City will be shipped directly to Huanglong City, where the production workshop will make various products, and then these products will be transported to Knoll City for loading on ships, and the transport ships will be sold to other planets or galaxies.

Therefore, when Yang Wuji sent intercity express before, the most frequent exchanges were Huanglong City and Nuoer City.

"After these monsters killed all the people in Zatai City, they didn't go to Noor City to meet the main monsters over there, but went in the direction of Huanglong City......"

While tracking at full speed, Yang Wuji guessed in his heart:

"Could it be that there are still resistance forces in Huanglong City that are resisting? Or is the Otherworldly Passage set up near Huanglong City? ”

As the distance from Huanglong City continued to get closer, Yang Wuji also saw the traces of otherworldly monsters flocking to Huanglong City from Noel City.

This made him even more sure of the speculation in his mind.

Half an hour later, the shadow of Huanglong City gradually appeared in the distance, and before Yang Wuji could get close, he saw a large number of otherworldly entities in the distance, and these monsters were full of shadows, crowded into dozens of thick circles, and surrounded the periphery of the city.

Suddenly, in the depths of the monster encirclement network, a group of at least a thousand monsters were rushed into the sky by the nameless force, and then, as if losing gravity, they continued to accelerate into the sky and disappeared above the clouds.

"This ...... What the heck? ”

Yang Wuji was taken aback by the situation in front of him, and quickly slowed down and stopped to observe the situation.

This is unbelievable, he found that the reason why so many otherworldly entities gathered outside the city and did not enter the city was not because there were too many monsters in the city, but because they were blocked out of the city!

In the Divine Sense, a large group of large robots four or five meters wide and eight or nine meters high, all black, reinforced and iron-clad, like the same iron wall, constantly pushed pieces of otherworldly entities out of the city.

There are about a thousand robots, and they have no weapons of their own, but with their solid bodies, massive weight, and terrifying strength, they are able to keep otherworldly entities in front of them.

If the otherworldly entities plan to pile up a wall of flesh and climb up, these robots will collectively punch and break up the mountains of flesh that the otherworldly entities have piled up with a single punch.

"It's fierce!"

This kind of scene of robots fighting monsters, Yang Wuji had only seen it in movies and games before, and when he was present at the scene, he was immediately amazed.

Even those non-commissioned officer-level monomer mechs that are powerful enough to kill seven in and seven out of the monster group can't beat the momentum of these robot walls when the number is scarce.

"Who is controlling these robots? And their purpose is only to push monsters out of the city? ”

Yang Wuji turned on the stealth and invisibility, flew to the sky above the robot wall, and found that the number of robots was far more than he had imagined.

There were about four or five thousand in total, and each one was close together, and the threads were seamed together, forming a hollow circular open space.

In the middle of the circular clearing, there is a strangely shaped machine that looks like a cash register with a giant chestnut on its top.

Three figures were busy near the machine.

The trio, two women and one man, one of whom was a young woman with thick eyebrows, big eyes, wheat-colored skin, a sturdy build, with a long ponytail and a tight orange overalls, was standing in front of the console of the giant machine, her hands quickly typing something.

Another middle-aged man has short brown hair, good facial features, and is also wearing a black tight-fitting overalls.

He stood on the pedestal of the giant machine, holding a scanner-like fan-shaped tool in his hand, and was constantly scanning around, and the glasses-shaped display on his face was constantly swiping the screen.

The last girl in her early teens, wearing a purple beanie hat to cover her hair, a hip-hop white T-shirt and a green camisole jumpsuit, and a half-covered helmet like VR goggles on her face, stood stiffly in place, occasionally swinging her fists.

Her fists swung at the same frequency as those robots.

"Is that her? She's controlling so many robots by herself? ”

Yang Wuji was a little surprised.

At this time, the woman with a ponytail operating the console suddenly shouted at the man standing on the machine:

"Isaac, I'm here!"

"Well done, Alyx!"

The man named "Isaac" gestured to the ponytail woman with a thumbs up, and then bowed his head and shouted to the girl who controlled the robot:

"Eva, buy me 1 minute!"

"No problem, Boss!"

The girl shouted, licked her lips, and then suddenly crouched down, and then frantically swung her fist forward like a fool, muttering:

"Ahh

A total of four or five thousand large robots squatted down at the same time as Eva's movements, stretched out their fists and swung sharply in front of them.

It looks stupid, but the effect is amazing.

An otherworldly entity surrounding a robot. Suddenly, like a fallen leaf, he was scattered by the robot wall, and soon cleared a lot of space.

"Boom!"

A loud bang came from the giant machine in the middle of the clearing, and then the chestnut-like top of the machine suddenly cracked like a flower bud, and several thin black "petals" flew out of it, flew into the sky, and flew towards the group of otherworldly entities in the distance.

The "petals" expanded rapidly as they flew, and in the blink of an eye, they stretched into several huge wire nets with a size of dozens of square kilometers, facing a large number of otherworldly entities.

These wire meshes are lightweight, yet very tough, and the mesh is very tight and automatically shrinks to close the loop.

After countless sucking spirits and flesh eaters were covered by the giant net, they couldn't break free for a while, like countless mosquito masses surrounded by black stockings.

"Is this to capture the monster alive?"

Yang Wuji looked confused.

"Here we go! Thirty seconds countdown! ”

Before he could think about it, Isaac, the middle-aged man below, shouted again, and after shouting, he turned over and jumped off the machine, and Eva, who was carrying the control robot, ran away, followed by Ponytail Alyx.

At the same time, the large robots around them also suddenly accelerated and changed formations, like cheerleaders who had been rehearsed countless times.

First, the four robots formed an iron cube and let the three Isaac hide in it.

Then the rest of the robot nesting dolls were quickly stacked around the iron cube, and soon a larger "box" was built outside the iron cube.

Yang Wuji felt unusual from this series of movements, and hurriedly increased the altitude of his flight.

Thirty seconds passed, and all he could feel was a strange fluctuation coming from the giant machine that had been left in place by the three of them.

"It's ...... Magnetic? It doesn't seem to be quite the same as normal magnetism......"

Yang Wuji distinguished the nature of the fluctuations, and then saw that the few otherworldly monsters that were wrapped in huge "stockings" suddenly seemed to be grabbed by an invisible giant hand, and gradually dragged towards the giant machine.

The speed is getting faster and faster, and even kicks up a puff of dust on the ground.

"Poof!"

The nearest monster net pocket smashed into the giant machine, and the huge weight instantly flattened the machine.

But the magnetic force of the net not only did not weaken, but increased as the machine was damaged!

"Puff puff!"

There was a dull loud noise, and several giant nets were attracted by the force and smashed together, like several sandbags that had been deliberately thrown into a pile.

There are thousands of monsters in the net, constantly emitting strange howls, and some otherworldly entities at the edge of the nets are smashed flat at the moment when the nets collide.

But this is not the end, the inexplicable magnetic force is still strengthening, and Yang Wuji observes through his divine thoughts that the fine metal nets that hold the otherworldly entities seem to be shrinking themselves.

The tough metal mesh is like a sharp blade with a huge suction, gradually cutting through and slicing through the skin, muscles, and even bones of otherworldly entities.

In the end, after all the metal nets cut off all the otherworldly entities that were trapped, they successfully condensed into a dark golden metal ball in the place where the giant machine had been placed.

And the thousands of otherworldly entities have also been cut into countless pieces and piled up into a literal huge mountain of meat.

"Good fellow...... If only I had this monster-killing efficiency. ”

Yang Wuji enjoyed watching the drama in the sky, and couldn't help but sigh.

I had confirmed it before when I was in Noir City, as long as it was not an otherworldly entity that Yang Wuji personally killed, the cultivation system would not be able to absorb the aura and increase his cultivation, otherwise just relying on the aura of this wave of dead otherworldly entities would be enough for him to fill up all his attributes and skills.

After the admiration, Yang Wuji was just about to fly down to study what the metal ball formed by the net pocket was something, but he inadvertently glanced at the "cube doll" composed of robots not far away, and found that the cube had no intention of being lifted, so he quickly stopped and continued to watch.

Sure enough, a few seconds later, the dark golden metal ball that had been condensed by the net and made it flawless suddenly exploded!

Countless metal filaments with tremendous power frantically threw outward, throwing the flesh and blood of the otherworldly entities that had been shattered and could no longer be broken like a rain in the sky.

At the same time, those wires that frantically flicked outward like knife light also cut off some "fish that slipped through the net".

Yang Wuji was at a high altitude, with amazing speed and reactions, and naturally easily dodged the explosion of the metal wire, but the "robot nesting doll" not far from the metal ball was not so lucky.

A steady stream of metal filaments shredded the cubes composed of robots layer by layer, until only two or three layers of the core remained, and the metal cutting storm subsided.
