After groping around the corpse, Lin Chi found a rusty key from the already decaying rags.

Unlike the normal quest items, this key does not show an item description, and although the surface is covered in a layer of dark red rust, the whole is still intact.

Obviously, the key must have been made of a special material, perhaps a spaceship hull or something.

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

- What is it?

The flashlight's circular circle of light casts a shadow of darkness ahead, then is blocked by a robot with a black shell.

The height of that thing was about three meters, about the same as Lin Chi's scrapped power armor. However, unlike the power armor that is close to a humanoid shape, this robot has sharp edges and corners on its body, without a trace of soft arcs, and its arms are unusually slender, which should be the position of both hands, and each has a chainsaw installed.

Unlike the power armor with legs, the robot has tracks and metal wheels mounted underneath its body. A track movement mode that is more efficient than a mechanical leg is adopted.

"Debugging...... The system reset successfully, fixed the annihilation parameter to 37, and the debugging was completed. ”

Its cube-shaped head lit up with a faint blue light, and the tone of its voice was like black iron frozen into ice, with a cold metal aura.

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

Abyss Guardian F93, a heroic NPC, unrecruitable.

"Damn, did I see your brother F92 in New York?"

Lin Chi was complaining, and he had already taken out the taser gun in his hand, but the F93's movements were extremely strange, and he had already rushed in front of him in an instant, leaving him no chance to shoot at all-

With a dangerous buzz, the frantic chainsaw struck head-on with a savage air current, and Lin Chi, who had turned on the horn of war, retreated violently, avoiding the blow with his powerful physical attributes. But the robot was still chasing and fighting, and before Lin Chi could take a breath, he had already rushed over again!

- Is this guy a mad dog......

In the face of this robot's "rabies tactics", Lin Chi was also a little embarrassed at this time, and finally seized the opportunity to shoot, and the electric shock dart from the taser gun hit the black armor on the chest of F93. And then......

Nothing happened.

"The stun gun didn't work on it?"

Seeing that the robot was still moving at high speed, Lin Chi put away the taser gun, turned around and ran backwards, and the robot holding two chainsaws chased after him, spreading its slender arms, like an "innocent girl" who ran towards the male god with flowers in her hands.

"Please wait, there will be no pain." F93 made an icy sound.

"Can I you......" Lin Chi replied rudely to the other party's words, and continued to run backwards.

With the attribute bonus of the War Horn, he can still maintain the same speed as the robot for the time being, but the "Abyss Guardian F93" seems to have unlimited power, and the speed of the pursuit shows no signs of slowing down.

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

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

While rushing forward, Lin Chi took out a light machine gun with plenty of ammunition from his backpack, and suddenly turned around and poured a rain of bullets at the F93, a large number of bullets that were enough to blast humans into pieces, and blasted a large number of sparks on the robot's body. But......

Still nothing happened.

The bullets that hit the robot's shell were all bounced off, and two of the ricocheting bullets that bounced back almost hit Lin Chi's head. The impregnable armor on the F93 is obviously not something that can be solved by machine guns alone!

- Is there no way?

Lin Chi continued to run wildly, and the robot rushed over with two chainsaws, and his body draped in heavy armor looked like he couldn't find a flaw at all.

However, the weakness of this robot is actually very obvious:

Since it moves through tracks and metal wheels, as long as it can break its tracks, it can stop this creature's pursuit completely!

However, on the front of the opponent's body, black heavy armor is installed, and only by attacking from the side can you win-

Buzzing......

While Lin Chi was thinking, the robot seemed to increase its power, rushed in front of Lin Chi again, and slashed at his head with the blade of the chainsaw.

Seeing that he couldn't dodge, Lin Chi used the body of the light machine gun in his hand to block the chainsaw waved by the robot's left hand, and a piercing sharp noise erupted from his ears, and the sparks erupted from the position where the gun body and the chainsaw came into contact, reflecting the underground cave within a radius of fifty meters.

At that moment, Lin Chi's hands holding the gun were numb, and then, the chainsaw in the robot's right hand swung over from the defenseless other side!

- Oops.

Realizing that he was about to die in a second, Lin Chi's consciousness entered a high-speed state at that moment, and he was quickly looking for a solution in his mind.

Then, the drawing technique of a certain Brazilian swordsman suddenly froze in his consciousness.

Bang bang bang......

The muzzle of the machine gun in Lin Chi's hand suddenly moved down, blasting a large number of bullets at the robot that was close at hand, and his footsteps were floating, with the help of the recoil of the machine gun and the airflow brought out by the close-range fire, his body flashed back five meters away, successfully avoiding the chainsaw swung by the robot.

"Learn about gunpowder drawing?"

Lin Chi said as he opened his legs again, and circled with the robot that was chasing after him. The Guardian F93 should have been given the order to "shoot and kill", and it continued to pursue him.

- As long as you can break the opponent's tracks, you can kill the guy, so now the question is: how to go around the side of the robot.

No matter how he changed direction, the robot was chasing after him, and the small "base" under his body was also constantly turning, and the agility was not at all like that of an unmanned machine.

"Someone can't be remotely controlled, right?"

Thinking of this, Lin Chi seemed to have a picture of a scientist sitting in front of the screen, holding a controller and playing a game with great interest. If that were the case, he would definitely end up in the home of scientists......

There is no flaw in the way the other party moves, and in this case, you can only create flaws by yourself.

Thinking of this, Lin Chi, who was running forward, suddenly made a ninety-degree turn, and jumped out like a kangaroo, although the robot's movements were also fast, but the base under its body still needed 0.5 seconds to rotate-

And this 0.5 seconds is enough for Lin Chi to shoot a bullet that hits the track from the side!

Lin Chi turned around in a dashing manner, and while his legs continued to step in the opposite direction, more than two dozen bullets erupted from the muzzle of the gun and blasted towards the robot's "lower three roads".

At close range 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." The robot said.

The F93, whose chassis was attacked, did not stop because of this attack, did not even slow down at all, and was still pursuing the marked enemy. However, Lin Chi, who was still in the situation of escaping, showed a smile on his face because he noticed a certain detail.

- This guy's game is a little shaky.

He could see very clearly that the robot's body "trembled" violently when it made a sharp turn and was shot in the chassis, and although it immediately returned to normal, there were still flaws that could be exploited.

The chassis of this combat robot is not large, and the main weight is concentrated in the upper body, even if it can't destroy its chassis, if you can find a way to make it fall to the ground......

Thinking of this, Lin Chi, who was still running forward, suddenly stumbled and fell to the ground, and the robot instantly appeared beside him, and two chainsaws cut towards the ground.

At the last moment before being slashed, Lin Chi suddenly rolled to the right, taking advantage of the robot's pause, and fired at the robot's chassis at close range with a machine gun in a lying position on the ground.

And by this time, two chainsaws had already slashed at his chest!

At the moment of life and death, the speed of time in Lin Chi's eyes seemed to have slowed down, his eyes seemed to be lit with flames, and eight big words appeared in his mind:

Imperial City PK, the winner is king!

As soon as his chest was hot, followed by a blazing pain, the killing machine codenamed "Abyss Guardian F93" suddenly fell to the other side, and green smoke came out from inside the chassis, and the saw blade that was supposed to cut through Lin Chi's chest only cut through his protective clothing and a thin layer of skin and flesh on his chest.

"Die......"

Lin Chi, who was still spurting blood from his chest, finally breathed a sigh of relief when he saw that the robot's tracks off the ground began to idle.

The machine, unable to move forward, once again emitted a cold electronic voice: "Debugging...... At the end of commissioning, it cannot be moved, and the system enters the power-saving state. ”

Before the words fell, the blue light on the robot's head suddenly went out, and the power wheels of the chassis stopped spinning, and this terrifying killing machine finally stopped pursuing.

"Haha...... Belch. ”

After laughing twice, he was interrupted by the pain that erupted in his chest, Lin Chi took out the bandage from his backpack, got up slowly, sat on the hard ground covered with dust, and began to bandage his wounds.

By now, the fact that this place is a secret base for scientists is basically a foregone conclusion. However, after experiencing the battle just now, the doubts in Lin Chi's heart not only did not disappear, but deepened a little.

- Judging by the dust on the ground and the decay of the corpses, the base must have been abandoned for many years. In other words, over the years, the technical ability of scientists has not only not improved, but has really declined?

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

So, what happened to make them lose their underground technology?

Lin Chi pondered the unsolved puzzle while bandaging his wounds, and by the way, wrapped the damaged position of the protective suit with a bandage.

While tending to the wound, his gaze stayed on the robot that had stopped working next to him, staring at the hard metal shell of the other party:

This robot that is still functioning must have a computer installed inside, and if we can find its storage device and read the information stored in it, we should be able to figure out what the condition of this underground base is.

Although I don't have hacking skills, I can only give it a try......

Thinking of this, Lin Chi, who had bandaged his wounds, tightened his grip on the machine gun, cautiously stepped forward, beware of the chainsaw that might be waved at any time, and his body began to enter the melee range of the Guardian F93.

He held his breath and stared intently at the fallen robot, then slowly bent down and began to take a closer look at the robot's body, looking for a place to take it apart.

What he fears most now is that the robot will suddenly start again. Recalling the tragic situation of being chased and killed just now, Lin Chi also oozed a few beads of sweat on his forehead.

- Don't move.

- Don't move.

He repeated the phrase in his consciousness as he shoved the machine gun back into his backpack and reached for the robot's cold body.

When his fingers touched the shell of the robot, a fiery sensation came through the gloves of the protective suit, Lin Chi retracted his hand violently, waited for a while, and made sure that the other party did not move, before reaching over again.

At this time, Lin Chi was like a lewd man on the bus who secretly stroked a beautiful woman sleeping next to him, for fear that his actions would wake up the other party. Although this metaphor is vulgar, it is indeed the most appropriate comment for his current situation......

Guardian F93, which had just stopped working, still had a scorching temperature in its steel body. It seems that the heat dissipation of this old-fashioned robot should not be very good, and a lot of the heat created when the engine is running should be left in its body.

No one would have a robot's "brain" mounted on a chassis or arm, and the computer built into it should be somewhere in the head or torso. And the focus of Lin Chi's search is precisely these two positions.

Is there a place on the shell that can be disassembled?

Lin Chi shone a flashlight on the robot's body, looking for the location of the other party's "core" at close range. After about a minute, he noticed that there was a square piece of armor on the back of the robot that seemed to protrude slightly.

- Is this it?

Lin Chi carefully observed the armor plate and found an extremely small gap next to it. Seeing this scene, he also 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 this thing open.

Click!

With a crisp sound, the armor plate bounced outward and landed on the ground next to it. Behind the robot, instead of a computer screen or keyboard, another pitch-black metal plate appears with a red button on it.

- What does this mean?

Facing the button that seemed to reveal a dangerous aura, Lin Chi fell into deep thought again.
