Chapter 141 Drones enter the city!

Abnormal behavior of the drone group on the surface?

Looking at the warning information in the holographic projection, Chen Fan's face changed slightly.

Thinking that the several micro drones released earlier had not yet returned to the underground city, Chen Fan quickly gave an order to Yi.

"Yi, show the specific picture!"

As soon as the voice fell, the exploration picture from the micro drone appeared in the holographic projection.

In the lush forest, the Hercules bulldozer, which was as big as a hill, was like a sleeping beast, lying quietly on the ground.

And those intelligent drones that were originally circling around the bulldozer have changed their action mode-they are like frightened birds and began to continuously lower their flight altitude!

In just a few seconds, a large number of intelligent drones all fell into the lush forest, relying on their agile postures to shuttle between the tree trunks, as if looking for something.

The exclamations of Hua Yiyang and other members of the law enforcement team came from the side. The scene on the ground brought a lot of shock to these inner city residents who had never left the underground city.

"So many drones?"

Hua Yiyang's face was gloomy: "Damn intelligent machines... What on earth do they want to do?"

Reality quickly told him the answer.

In just one minute, these drones accurately found the entrance to the passage of the Mechanic Cult into the underground city in the lush trees.

In the eyes of the crowd who couldn't believe it, these drones lined up in a neat formation and drilled into the passage with incredible precision!

[Warning! ]

[Intelligent drones have entered the underground city passage and are expected to enter the underground city in ten minutes. ]

As the orange-yellow warning message popped up in the holographic projection, the surroundings suddenly fell into a dead silence.

Intelligent drones are coming!

After a short silence, everyone present reacted.

Hua Yiyang's face full of flesh was a little pale, and the original fierce look had completely disappeared: "Intelligent, intelligent machines are coming, what should we do?"

The momentum that threatened to protect the underground city just now had long dissipated.

Seeing this, Chen Fan couldn't help but frowned.

A fluorescent green light appeared on his right hand, and the PW-1 small plasma launcher disguised as a small pistol appeared again.

Without any hesitation, he gave the order in a deep voice: "Go and inform those big shots in the inner city, tell them that the drones of the intelligent machines are coming, and let them be prepared."

"What, what preparations?" Hua Yiyang was obviously confused, and the flesh on his face trembled violently. "Escape, escape?"

Before Chen Fan could speak, Hong Chengdong had already reached out and picked up a light machine gun, and then reached out to pull the bolt.

Click.

With the crisp sound of rebound, Hong Chengdong asked coldly: "All the passages are blocked."

"Run? Can you run away?"

"If you don't want to die, pick up your weapons and fight those drones!"

...

The entrance to the east passage of the underground city.

In order to avoid getting in the way, the bodies of the two cyborgs had been thrown far away to the corner at the edge of the underground city. Needless to say, Jolson, who was shot in the back of the head by Hong Chengdong, must have died. As for the female cyborg who had taken a fancy to Chen Fan as soon as she arrived, she was shot by Isa and lost her life completely.

A huge holographic projection appeared in front of Chen Fan.

It showed a holographic map of the entire Kukan underground city. At the moment when the intelligent mechanical drone entered the underground city, Chen Fan released the only remaining detection drone.

Under the control of Yi, the detection drone quickly completed the mapping and modeling of the underground city. The

entire Kukan underground city is circular, with a total of 512 huge load-bearing columns with a diameter of more than three meters evenly distributed in the Kukan underground city, supporting the arc-shaped concrete dome above the head.

And around the underground city, there are more than 300 mining platforms, each of which is connected to no less than ten different rails.

In other words, there are no less than 3,000 passages leading to the ground around the Kukan underground city.

The worst thing is that these passages are interconnected!

When Chen Fan discovered this, his face suddenly became ugly.

This means that although all the intelligent drones entered from the same passage, they can appear at any mine station platform with the help of the interconnected underground passages around the underground city!

There is no doubt that this will bring great difficulties to the defense work!

In fact, these intelligent drones did so.

According to the results sent back by the detection drone, these intelligent drones did not honestly follow a passage to the end, but drilled into the miscellaneous forks in the passage!

Looking at the yellow dots that gradually surrounded the underground city model in the holographic projection, Chen Fan's face became more and more ugly.

Blocking all exits, it seems that the intelligent drones are determined to exterminate this underground city!

Listening to the buzzing sound coming from the passage in front of him, Hong Chengdong wiped the light machine gun in his hand with a tense face.

He knew that what he would face next would be a fierce battle!

Beside Hong Chengdong, a salvage worker was moving a large amount of construction waste from the outer city area to build temporary cover facilities.

The inner city, which had been quiet all the time, also began to become chaotic.

There were cries and wails one after another, and even the sound of gunfire.

The sound of leather shoes stepping on the concrete floor came from behind, and Hua Yiyang's figure appeared in front of Hong Chengdong and Chen Fan again.

Unlike before, Hua Yiyang was followed by hundreds of law enforcement team members wearing uniforms and fully armed.

Although most of them were gunpowder weapons, the light and heavy machine guns and a large number of artillery still gave the people present a bit of confidence.

"How is the inner city?" Hong Chengdong turned his head to look at a ray of fire in the distance and asked Hua Yiyang, "There are intelligent drones in all the passages of Kukan Underground City. These big shots are not still thinking of escaping, right?"

Hua Yiyang showed a smile that was uglier than crying: "But there are still some in Hai'an Underground City."

"Most of the powerful people in the inner city have taken the tram to Hai'an Underground City. If nothing unexpected happens, the tram should be running soon."

"Fuck."

Hong Chengdong cursed in a low voice and spat: "These beasts!"

...

The buzzing sound came from all directions and echoed over the sky of Kukan Underground City.

This further aggravated the tense atmosphere in the underground city.

Chen Fan's eyes moved slightly. In the holographic model of the underground city, the yellow dot symbolizing the intelligent drone had already touched the edge of the city.

"Here it comes!"

Chen Fan shouted in a low voice, and a fluorescent green light flashed in his right hand, and an ellipsoid device that looked like a grenade appeared in his hand.

EM-1 plasma grenade.

Plasma grenades with moderate power and little damage to the environment are the conventional weapons of most investigators.

With the corresponding information flashing through his mind, Chen Fan did not hesitate at all. He threw the plasma grenade, which was only as big as a baby's fist, directly into the passage ahead with a strong swing of his right hand.

At the same time, two spherical devices slowly rose beside Chen Fan.

Although they looked similar to detection drones, the functions of these two spherical devices were completely different - human-linked small-arms floating self-propelled turrets (special version for investigators of the Dangerous Technology Administration).

They are referred to as floating guns.

Buzz!!!

The dull humming sound suddenly became high-pitched!

Under the gaze of everyone, dozens of silver-white intelligent mechanical drones rushed out of the deep passage!

It happened in a flash.

Boom!!!

The plasma grenade exploded instantly, and a ball of blazing blue fireball suddenly bloomed at the entrance of the passage. The dark blue high-temperature plasma was like a small star, instantly swallowing up the dozen drones!

But the humming sound did not dissipate!

A steady stream of intelligent drones gushed out from the passage in front of us.

No! Not just the passage in front of us!

Almost at the same time, a large number of drones gushed out from all the more than 300 mine cart passages in the entire underground city!

There were more than a hundred drones, and as few as a dozen!

The moment they left the passage, the speed of these drones suddenly increased, and while they rushed straight into the sky, a short gun barrel also stretched out from their abdomens.

Puff puff puff...

Without any fire, accompanied by a dull sound, bullets like marbles flew rapidly towards the buildings and residents on the ground!

Small electromagnetic machine guns! !

The bullets driven by electromagnetic force quickly formed waves of metal storms, raging wildly in the Kukan underground city!

After a short wait, the counterattack of the underground city also came. The

roar of artillery continued to sound, and a large number of tracer bullets formed a dense anti-aircraft firepower network at the entrance of the underground city passage to intercept the uninvited guests from the surface!

The flames of the drone explosions continued to light up near the underground city passage.

But...

the good times did not last long.

After the first wave of concentrated firepower attacks, the combat quality problems of the residents of the underground city were completely exposed.

The speed of changing ammunition was too slow, the personnel replacement was not timely...

all kinds of problems caused some omissions in the originally dense anti-aircraft firepower network!

When a drone successfully passed through the anti-aircraft firepower network, the horror of the intelligent machine finally manifested itself at this moment!

Under the control of the internal AI, it quickly raised its flight altitude, constantly avoiding the ground anti-aircraft firepower, while relying on the small electromagnetic machine gun on its abdomen to attack the underground city residents holding heavy weapons with great accuracy!

In terms of accuracy, how could these underground city residents who had almost no combat experience be the opponents of the intelligent machine?

Just a face-to-face, one of the passages in the Kukan underground city was completely lost!

The intelligent machine quickly adjusted its offensive strategy.

Break the surface with a point!

They avoided the east passage where Chen Fan was, and began to attack the passage near the lost point.

The strategy worked-but in just a few tens of seconds, dozens of drones had appeared over the Kukan underground city!

As the passages were lost one by one, the number of drones in the underground city was still growing at a speed visible to the naked eye! !

ps: Thanks to the leader of 【Naming is really troublesome】!

Thank you! May you have a big fortune in the new year! !

Hiss...

After careful calculation, I already owe six chapters. I have a lot of things to do recently. I will write more in the next few days and start to add more chapters after accumulating some manuscripts!
