The unmanned aerial vehicle (UAV) using vertical take-off and landing technology quickly covered the entire airspace of Kayaland, and began to carry out a brutal massacre of the soldiers below.

The armored vehicles and tanks used by the mercenaries were like lambs to the slaughter under the "sparrows", and they could not hurt the plane at all. Although there are also man-to-air missiles that are returning fire, the hand-held weapons of a few shooters alone cannot affect the aircraft fleet in the air.

"Are these mercenaries fucking crazy......

Woods lay on the ground with his back to the sky, looking at the dense formation of drones like seabirds in the air, and he didn't even dare to get out of the atmosphere.

Due to the large number of "sparrows" nearby, the two people who remained in the ruins could only continue to lie on the ground and pretend to be dead. Explosions in the city rang out like a frenzied drummer playing.

Lin Chi turned over slightly, just in time to see a dark blue "sparrow" flying through the sky directly above, four rotatable jet engines, and blue and white flames erupted from the vents to the rear.

- Oops.

Seeing the red light from the nose of the "Sparrow" sweeping over, Lin Chi, who was still lying on the ground, tensed his muscles all over his body, ready to run away. Although it is impossible to escape from the drone even if you want to run without skills, you can't do that much now.

"Ready to ......," he signaled to Woods beside him, using his throat microphone.

Woods held his breath, ready to "hug his head" at any moment, and just as the two were about to take a desperate gamble, the drone flew over their heads, as if it hadn't detected the two, and flew straight towards the southwest block.

- What's the situation?

Lin Chi and Woods looked at each other and were silent for a while.

If the "Sparrows" had installed a far-sighted infrared imaging system, they would have been bombarded to slag long ago. Since the "Sparrow" flew away directly, that is, this drone did not use thermal imaging equipment.

So the question is, how exactly does it determine the enemy's position and then launch an attack?

Judging from the age of the map in Kayaland, the built-in automatic attack system of this drone should not be advanced enough to judge the target by directly analyzing the image. If these things aren't using thermal imaging, it's worth thinking about how they can pinpoint enemies and attack.

When Lin Chi was thinking about it, he saw an explosion on the street two hundred meters away, and a group of mercenaries rushed out of the smoke with rolling and crawling, even throwing away their weapons, and scattered in all directions to escape.

Unfortunately, before they could run a few steps, the two dark blue "sparrows" in the sky above them began to turn around and aimed the muzzles of their 30mm cannons at the mercenaries who were scattering and fleeing.

Da Da Da ......

The cannon under the Sparrow's fuselage spewed a large amount of flames, and several mercenaries who were fleeing were suddenly blown to pieces, their bodies disappeared into the smoke of the explosion, and the charred stumps and severed arms rose into the air.

"Help......

The only remaining mercenary howled in despair, and his voice was drowned out by the loud sound of the explosion, and under the witness of Lin Chi and Woods, the killing lasted less than ten seconds before it ended.

"These hits so accurately......" Woods looked at the burning ground.

The accuracy of the Sparrow's shooting does not look like that of unmanned combat equipment. If these guys are really unmanned combat machines, as Special Operations Command claims, how exactly do they lock on to the enemy?

"Is it motion sensing?" Lin Chi whispered his inference.

INTERVIEWER In the early days of electronic devices such as automatic cameras, motion sensing technology was a very basic function.

For example, if a camera is set up in a fixed location in the field and used to shoot wild animals, if someone is sent to keep an eye on the camera 24 hours a day, it will undoubtedly waste a lot of time and energy. This camera senses that something is moving and starts shooting automatically.

As long as something moves in the frame, it will be sensed by the camera and automatically react accordingly. Now it seems that the detection mechanism of the "Sparrow" is likely to use this kind of motion sensing.

In this way, the reason why he and Woods survived can be explained - they were lying motionless on the ground, but they were actually captured by the camera, but because they did not make any movements, they were not judged to be enemies, and they were not attacked by drones.

If that's the case, it seems that the chances of escaping yourself are a little bigger......

Thinking of this, Lin Chi immediately switched the radio to the channel used by SOG, ordered the soldiers who had just been dispatched to stop their movements and stand by in place, and then whispered a new order to Woods:

"Move slowly to cover, make sure to be small, that thing may be attacking a moving target."

"Understood." The battle-hardened Woods responded immediately, slowly turning over from a supine position to a prone position that was easy to move.

The experienced Woods's movements can be described as unusually gentle, and he turned over like a slightly twitching corpse. Imitating his movements, Lin Chi also slowly turned over and changed his prostrate posture.

Then, the duo, hidden in the rubble, began to crawl forward in a very small way, as slow as a snail.

Under the observation of the "sparrow", the two "corpses" that moved in small increments slowly left their original positions and moved towards a dilapidated house to the east.

Although half of the house was blown down, it still had a roof, and as long as you entered there, you didn't have to worry about it in the open air.

While crawling slowly, Lin Chi was also observing the situation on the map:

Obviously, even those players who are capturing strategic locations will be attacked by drones. With the advent of drones, two strategic locations suddenly became unoccupied, and the original occupiers must have run away.

In addition to this, there are even worse guys in the ......

- Player "Chill Wind" has died.

The red tooltip grimly states the fact that the player was killed, and one of the remaining thirteen players has left the game. With the death of Cold Wind, the "dark basement" that was originally occupied by him has also become unoccupied.

Will the people who hide in the basement also be killed?

Lin Chi knew very well that it was impossible to attack the enemy in the basement with the "sparrow", a way to find the enemy through motion induction. The one who killed that player was probably another unmanned attack device that hadn't appeared here until now - "Bad Wolf", yes!

Now that the "evil wolf" has not appeared, they are relatively safe for the time being, but the way the evil wolf detects the enemy may not be the same as the sparrow, if the evil wolf appears here, he will be in danger.

Thinking of this, Lin Chi also slightly accelerated the range of his movements, and whispered to Woods with a throat microphone: "Try to hurry up." ”

The dark blue-painted "Sparrow" was still hovering in the sky, taking advantage of the fact that those drones were all going to slaughter the mercenaries, and Lin Chi and Woods' movements also became a little larger, crawling forward on the dusty streets, quietly slipping away from under the noses of the enemy.

Boom!

The ground beneath them suddenly shook, and a few seconds later, a dull roar was heard, and Lin Chi and Woods, who were lying on the ground, raised their heads slightly, looked in the direction where the sound sounded, and then witnessed an unbelievable scene.

"That's what it is...... Bad wolf. Lin Chi muttered to himself.

The first thing that catches your eye is the big feet covered in a silver metal shell, and the steel "thighs" that use hydraulic technology, a metal monster ten meters long, standing on the ground in the posture of a wolf, four slender mechanical legs supporting a huge steel body, tilting its head and opening its mouth to let out a howl to the sky.

The back of the "evil wolf" is inlaid with a large number of slender "needles", which look like erect hairs, from the shape of the head to the steel teeth in the mouth, all faithfully restore the appearance of the wolf, which should be the position of the eyeballs, and light up with two red lights. There's even a long tail mounted on the back of the body, with a large number of blades neatly arranged on it, which is terrifying just to look at.

"Why do you want to develop this kind of thing......" Woods' voice smacked of incredulity, "this form factor is so impractical." ”

"Maybe it's to put a sense of oppression on the enemy, or maybe it's handsome." Lin Chi smiled.

The use of this four-legged robot on the battlefield is actually not as reliable as a tank. But the appearance of the "Evil Wolf" is obviously much more domineering than that of the tank. The two missile launch tubes on the shoulders also fully demonstrate its firepower.

Lin Chi didn't know if the design of this drone was inspired by the Soviet Union's "horror robots", but the evil wolf did create a strong sense of oppression with a similar appearance like an animal, but other than that......

Oh!

The howl of the wolf soars into the sky, and the sound synthesized by electronic devices sounds as realistic as the howl of a wolf in the wild. The giant wolf raised its head, the red lasers in its eyes swept into the sky, and the "Sparrow" drones that had been patrolling nearby flew away from this area and went to other airspace.

"What is it doing here?" Woods asked, confused.

"Maybe you swear your own ownership of this place and disperse the other predators?" Suspicious of his own inference, Lin Chi's voice was also a little unsure.

I thought that only the "evil wolf" with a relatively restored appearance would make such a move, which was completely unexpected by Lin Chi. Now it seems that the designer of the drone may have some unusual obsession with the wolf as an animal, or he may be a severe second-class patient......

However, this move of the evil wolf instead provided an opportunity for the two lying on the ground. Without the dangerous watchers in the air, they wouldn't be as constrained as they were before.

"Withdraw ...... now"

Lin Chi gave an order, and the two of them crawled forward faster. Now the wolf's head is facing the opposite direction, and it's a great opportunity to leave.

Since they didn't know how the ground combat robot judged the enemy's position, they didn't risk getting up and running away, but continued to crawl on the ground while also observing the wolf's movements.

Whew......

The anomalously restored robot let out a low howl with its mouth full of steel fangs, then walked forward on all four legs, lowered its head, and threw its head into the ruins below.

"Hat-the-fuck......" Woods scolded.

- The robot named Evil Wolf actually picked up a relatively intact mercenary corpse on the ground like a real wolf, and then snapped into its own steel teeth.

Click!

With a crisp sound, the corpse's head and feet flew out to both sides, and the body was swallowed by the "evil wolf". Witnessing the unbelievable scene, Woods couldn't help but doubt his eyes: "Could this really be a wolf, just wearing a metal shell?" ”

"Have you ever seen a wolf this big?" Lin Chi gave him a blank look.

"Maybe it's mutated, nuclear radiation or something......," Woods said.

While arguing in a whisper, the two did not forget to continue to escape, and with the help of the debris of the building, they crawled two hundred meters behind the wolf, and finally arrived at their destination, the roofed building.

The sound of flesh being crushed by steel teeth echoed through the ruins, and the wolf was still searching for his food. Because the situation here was so weird, Lin Chi and Woods didn't have time to rest at this time, but were even more nervous than just now.

"Be careful...... I suspect it catches its prey by smell. Lin Chi whispered.

If this wolf-type robot really completely restores the habits of wolves, then it should be possible that it will find enemies through its sense of smell. But if that's the case, it means ...... This thing is many times more dangerous than the "sparrow" just now.

It's very simple to disguise the action, but it's difficult to cover up the smell, because it is the first time to see this kind of unmanned combat robot, Lin Chi can't judge what smell the other party is judging by, even if he puts some other smells on his body to try to cover up the traces, maybe he will want to cover it up and directly attract the attention of the evil wolf.

"Commander, what the hell are we supposed to ......," Woods asked, clenching his fists.

As the captain of SOG, Woods was almost stunned at this time, he was trained in hunting people and common battlefield vehicles, and the wolf-like giant robot was completely beyond the scope of the SOG army......

Not to mention Woods, even elite special forces such as DEVGRU and SAS are undoubtedly very difficult to deal with the "bad wolf". Because the gap between the enemy and the enemy was too great, Lin Chi had no intention of fighting at all, but just raised his hand and pointed to the back door of the house, and repeated the concise order again:

"Withdraw."

Relying on the two of them alone, fighting against the "evil wolf" is completely looking for death, no matter what, it is more important to save your life now.

Lin Chi leaned against the wall next to the door, slowly pushed the door open, and was about to leave the building, but a text prompt appeared again in his sight:

Kill two "wolves" to earn one point, commanders, please enjoy the hunt!

Seeing this line of text, Lin Chi was silent for two seconds, and said angrily:

"Bastard, are you kidding me?"
