After exploring the body, Lin Chi took out a rusty key from the already decaying rag.

Unlike ordinary quest props, this key does not show an item introduction. Although the surface is covered with a layer of dark red rust, the overall picture remains intact.

Obviously, this key should be made of special materials, perhaps something like the spacecraft shell.

After Lin Chi put the key into his backpack, he continued to move forward. But this time, before he took two steps, he heard a crisp "click".

——What?

The circular aperture of the flashlight hits the darkness ahead, and is blocked by a robot with a black shell.

The thing was about three meters tall, similar to Lin Chi's scrapped power armor. But unlike the power armor with a human shape, the robot was clearly angular, without a soft arc, and the arms were extremely slender. It should be the position of both hands, and each was equipped with a chain saw.

Unlike the power armor with legs, the robot is equipped with tracks and metal wheels under its body. It uses a track movement mode that is more efficient than mechanical legs.

"Default... the system reset is successful, the annihilation parameter is fixed to 37, and the debugging is over."

Its square-shaped head lit up a dark blue light, and the tone of the voice was like black iron frozen into ice, with a cold metallic atmosphere.

Then, a line of dark red words appeared in front of Lin Chi's eyes:

Abyss Guardian F93, hero-level NPC, cannot be recruited.

"Damn, have I met your brother F92 in New York?"

Lin Chi was complaining, and he had already taken out a Taser in his hand, but the F93's movements were extremely strange. He rushed to him in an instant, leaving him no chance to shoot-

Accompanied by the dangerous buzz, the wild chain saw rushed towards him with a barbaric airflow. Lin Chimeng, who opened the horn of war, then retreated, and avoided the attack with his powerful physical attributes. But the robot was still chasing and attacking him. Before Lin Chi could take a breath, he rushed over again!

——Is this guy a mad dog?

Faced with the robot's "rabies tactic", Lin Chi was also a little embarrassed at this time. He finally seized the opportunity to shoot. The electric shock dart shot by the Taser spear hit the black armor on F93's chest. Then...

Nothing happened.

"The stun gun has no effect on it?"

Seeing that the robot was still moving at high speed, Lin Chi put away his Taser, turned around and ran back. The robot holding two chain saws chased him reluctantly, spreading his slender arms, like a "pure girl" running towards the male god holding flowers in his hand.

"Please wait a moment, there will be no pain." F93 made a cold sound.

"Can I go to you..." Lin Chi answered the other party rudely and continued to run backwards.

With the attribute bonus of the War Horn, he can maintain a similar speed as a robot for the time being, but the "Abyss Guardian F93" also seems to have infinite power, and the pursuit speed shows no sign of slowing down.

Lin Chi knew that if this continued, when the special effects of the "War Horn" ended, he would definitely be instantly killed by the robot, and he would not even have the chance to fight back!

So, is there any weapon in the backpack that can destroy that guy's armor?

While running forward, Lin Chi took out a light machine gun with ammunition from his backpack, and suddenly turned around and poured a rain of bullets at the F93, which was enough to knock humans into pieces, and bombarded the robot's body to bring out a lot of sparks. But...

Or nothing happened.

The bullets hitting the robot's shell were bounced off, and two of them bounced back almost knocked Lin Chi's head. The solid armor on the F93 was obviously not solved by machine guns alone!

——Is there nothing I can do?

Lin Chi continued to run wildly, and the robot rushed over with two chain saws, wearing heavy armor, and seemed to be unable to find any flaws.

However, the weaknesses of this robot are actually very obvious:

Since it moves through tracks and metal wheels, as long as it can interrupt its tracks, the guy's pursuit can completely stop!

However, the opponent's body is equipped with black heavy armor, and only by attacking from the side can you have a chance of winning.

Buzz...

While Lin Chi was thinking, the robot seemed to increase its power and rushed to Lin Chi again, waving the chain saw blade to chop at his head.

Seeing that he could not dodge, Lin Chi used the light machine gun body in his hand to block the chain saw waved by the robot's left hand. A sharp noise erupted from his ears. Sparks erupted from the position where the gun body and the chain saw came into contact with each other lit up the underground cave within a radius of 50 meters.

At that moment, Lin Chi's hands holding the gun were numb, and then the chain saw in the robot's right hand swung over from the other side without any defense!

——Oops.

Realizing that he was about to die in one second, Lin Chi's consciousness entered a high-speed operation at that moment, and quickly looked for a solution in his mind. The scenes he experienced after entering this game flowed through his eyes like a revolving lantern.

Then, a Brazilian swordsman's "sword-telling" sword drawing technique suddenly became frozen in his consciousness.

Bang bang bang bang...

The muzzle of the machine gun in Lin Chi's hand suddenly moved downward, and blasted a large number of bullets at the robot that was close to him, and his footsteps floated up. With the help of the machine gun's recoil and the airflow brought by the close-range fire, his body flashed five meters backward, successfully avoiding the chain saw swinged by the robot.

"Let's learn about gunpowder sword drawing?"

Lin Chi said as he stepped aside and formed a circle with the robot who was chasing him relentlessly. The Guardian F93 should have been set to "kill without any reason" and is still continuing to pursue him.

——As long as you can interrupt the other party’s track, you can kill that guy, so the question now is: how to go around the side of the robot.

No matter how the direction is changed, the robot is chasing him in a state that is facing him. The small "base" under the body is also turning, and its flexibility is not as flexible as an unmanned machine.

"Can someone control the remote control?"

Thinking of this, Lin Chi seemed to see a scene of a scientist sitting in front of the screen, holding the handle and playing games with great enthusiasm. If this is true, he would definitely have brought the scientist's hometown...

There is no flaw in the other party's movement method. Since this is the case, you can only create flaws by yourself.

Thinking of this, Lin Chi, who was running forward, suddenly turned 90 degrees and lowered his body like a kangaroo and jumped out. Although the robot was moving very fast, it still took 0:5 seconds to rotate the base under its body.

And these 0:5 seconds were enough bullets that Lin Chi hit the track from the side!

Lin Chi turned around casually, and while his legs continued to step in the opposite direction, more than twenty bullets were sprayed out of the muzzle and blasted towards the robot's "lower three ways".

At a close distance of less than ten meters, most of the bullets accurately hit the robot's chassis, hitting the wheels and tracks, creating dazzling sparks.

"Please don't resist." said the robot.

The F93, whose chassis was attacked, did not stop because of this attack, and did not even slow down. It was still chasing the marked enemy. However, Lin Chi, who was still in a runaway position, had a smile on his face because he noticed a detail.

——This guy’s lower order is a bit unstable.

He saw it very clearly. When he made a sharp turn and the chassis was shot, the robot's body suddenly "trembled". Although it immediately returned to normal, there were still flaws that could be exploited.

The chassis of this combat robot is not large, and its main weight is concentrated on the upper body. Even if it cannot destroy its chassis, if it can find a way to make it fall to the ground...

Thinking of this, Lin Chi, who was already running forward, suddenly staggered and fell to the ground. The robot instantly appeared beside him, and two chain saws cut towards the ground.

At the last moment before being cut, Lin Chi suddenly rolled over to the right. Taking advantage of the opportunity of the robot stopping his pace, he aimed the machine gun at the robot's chassis and opened fire at close range in a position of lying on the ground.

At this time, two chain saws were already scratching towards his chest!

At the critical moment of life and death, the flow of time in Lin Chi's eyes seemed to slow down. Flames seemed to ignite in his eyes, and eight very appropriate words appeared in his mind:

The Imperial City PK, the winner is the king!

As the chest became hot, the pain followed one after another. The murder machine code-named "Guardian of the Abyss F93" suddenly fell to the other side, and blue smoke came out of the chassis. The saw blade that was supposed to be cut through Lin Chi's chest, and only his protective suit and a thin layer of flesh on his chest.

"Go to die..."

Lin Chi, who was still bleeding in his chest, finally breathed a sigh of relief when he saw the robot's tracks that started to idle.

The machine that could not continue to move forward once again emitted a cold electronic sound: "Default... the debugging is over, it is not moved, and the system enters a power-saving state."

Before he finished speaking, the blue light on the robot's head suddenly went out, and the power wheel of the chassis no longer rotated. This terrifying killing machine finally stopped chasing.

“Haha…uh.”

After laughing for a moment, Lin Chi took out the bandage from his backpack, slowly got up, sat on the hard ground covered in dust, and began to bandage his wounds.

Now, the fact that this place is a secret base for scientists is basically a foregone conclusion. However, after experiencing the battle just now, Lin Chi's doubts were not eliminated, but became a little deeper.

——From the degree of decay on the ground and the degree of decay of the corpses, this base must have been abandoned for many years. In other words, over the years, the technical capabilities of scientists have not only not improved, but have actually declined?

If scientists use this robot on the surface of Mars, they will not be slaughtered by players. As long as they can improve the unreliable chassis of the robot and give it off-road ability, players and exiled criminals on this planet will probably be killed by this thing.

So, what happened that made them lose their underground technology?

While thinking about the unsolved puzzle, Lin Chi bandaged his wounds and wrapped the damaged area of ​​the protective suit with a bandage.

While treating the wound, his eyes remained on the robot that stopped working beside him, staring at the other party's hard metal shell:

This robot that can continue to operate must have a computer installed inside. If you can find its storage device and read out the information stored in it, you should be able to figure out what the underground base is like.

Although I don’t have hacking skills, I can only try it...

Thinking of this, Lin Chi, who had bandaged the wound, held the machine gun tightly and walked forward carefully, guarding against the chain saw that could be swung at any time, his body began to enter the melee range of Guardian F93.

He held his breath and stared at the falling robot intently, then slowly bent down and began to observe the robot's body up close, looking for a position to be disassembled.

What he feared the most now was that the robot suddenly started again. Looking back on the tragic situation he was chased just now, a few beads of sweat also oozed out of Lin Chi's forehead.

——Don’t move.

——Don’t move.

This sentence was repeated in his consciousness, and his hands stuffed the machine gun back into his backpack and reached towards the robot's cold body.

When the finger touched the robot's shell, a slight sense of heat came through the gloves of the protective suit. Lin Chi suddenly retracted his hand, waited for a while, and then reached over again after confirming that the other party had not moved.

At this time, Lin Chi was like a wretched man secretly stroking a beautiful woman sitting next to him on a bus, afraid that his actions would wake him up. Although this metaphor is relatively vulgar, it is indeed the comment that best suits his current situation...

The guardian F93, who just stopped running, still has a hot temperature. It seems that the heat dissipation of this old-fashioned robot should not be very good. A lot of the heat produced when the engine is running should be left in its body.

No one will install the robot's "brain" on the chassis or arms. The built-in computer should be somewhere on the head or torso. The focus of Lin Chi's search is also these two locations.

Is there any place on the shell that can be removed?

Lin Chi shines the robot's body with a flashlight, looking for the other party's "core" close to the location. About a minute later, he notices that there is a square armor on the back of the robot that seems to highlight a little.

——Is it here?

Lin Chi carefully observed the armor plate and found an extremely small gap next to it. Seeing this scene, he decisively took out the tiger claw hunting knife from his backpack, inserted the slender blade into the gap in the armor plate, and began to try to pry open the thing.

Click!

With a crisp sound, the armored plate bounced outwards and landed on the ground next to it. What appeared behind the robot was not a computer screen or keyboard, but another black metal plate and a red button on it.

——What does this mean?
Chapter completed!
