About 800 meters underground at the Coober Pedi military base, this is already the core of this underground world, a huge underground cavity dug by hand.

The elevator continued to descend, and there was nothing all around, only in the extreme distance could you see some honeycomb-like buildings, countless colors of lights shining through countless windows, and there were many small elevators running between the floors, all of them steel and concrete, and there was not a trace of soil in sight.

The entire underground cavity is in the shape of a cylinder, and the transparent tunnel of the elevator is in the center of the cylinder, and many tracks extending from the distant buildings are connected to the outside of the tunnel, making the tunnel look like a strange tree growing from the center of the earth.

Some of the electromagnetic cable cars travel through various tracks, which can quickly and easily pass people through hollow cylinders without having to go around a large circle, and can also take people to the only elevator that can run through the entire base and go to the ground, underground, or any height.

The rays of light from all directions were colorful and reflected on the dust in the cavity, forming a large area of colorful mist, magnificent and fantastic.

The elevator slowly descends through these fogs, as if you are in a mythical world with no end.

"Are we going to go to the bottom?" Livers didn't seem to have any intention of stopping.

"No, there's a plaza at the bottom, let's go to the main control room first and show you something." Green said.

Eventually, the elevator stopped at about 1,100 meters underground, and they took the electromagnetic cable car to the main control room, where dozens of people were working nervously in front of various electronic equipment.

Green walked over to a chair with a display screen in front and sat down, picked up a walkie-talkie on the table, and said, "Skunk, you now immediately transmit the video of the battle between the fifty-seventh, fifty-nineth, and thirty-fourth teams two days ago to the main control room Forty-one host, and ask for a complete video." ”

After about two minutes, feedback came from the walkie-talkie: "Commander, the video has been uploaded, please check it!" ”

"Divisional commander?" Lifus heard the skunk on the walkie-talkie call Green that, and asked suspiciously, "What kind of organization are we now?" ”

"Or else? We are just such a small number of people, can we still be called commanders? Green explained, "Guardian Independent Division, this is the name voted for by all the Chosen One, of course, I, the division commander, is also the result of the vote, if you were there at the time, I am afraid that this division commander will have to be the result of your vote." ”

The Chosen ones were all born on the same day, and were almost simultaneously removed from the artificial fibers that created them*, there was no order of seniority between them, and there was no dignity or inferiority, they were all equal, so whatever decisions were made, they needed democracy, they needed to consult the opinions of all the Chosen ones, and the most direct convincing thing for the Chosen ones was their individual combat effectiveness, and Lifus had always been the best in this regard.

Green tugged him in a chair from the side, but Livers didn't sit down, he stood behind Green's chair with his chin propped up on his elbows.

Green operated the mouse and clicked on the folder he had just received on the hard drive.

A gray-toned, real-time battle appeared on the display, a vast plain, the sky still overcast, but the ground was filled with explosions and shrill roars.

"This is an encounter between the three groups of fifty-seven, fifty-nine, and thirty-five and four, and the mecha team of the Alliance, which happened two days ago, we are going to sneak attack the enemy's large-scale particle fusion factory in South Carolina, North America, which may be able to cut off part of the energy supply in southern North America, and originally planned to use air strikes to directly destroy the target, but I didn't expect that the alliance would even use super metal to reinforce the factory defense system there, and it can't be destroyed at all, so we can only send ground troops."

Green looked at the screen and explained to Livers, "The EMP shells were very effective against them, and we quickly discovered this and used it to kill a large number of mechs in the early stage, which is one of the reasons why we were able to capture this place and gain a foothold. ”

"But the alliance quickly took measures, and the mechs they later built were all coated with anti-electromagnetic radiation, and it was difficult for EMP shells to kill them anymore."

"And what is the main means of dealing with these mechs now?" Lifus asked, since the high temperature, radiation, shock wave, etc., of the explosion could not effectively kill these mechas, then what qualifications did humans have to fight these machines?

"It's still an EMP bomb. But a direct hit on the target is needed to paralyze them for a while. Green said helplessly, "So everyone's main weapon now is the electromagnetic pulse*, which is fired at close range." ”

Approaching these specially developed killing machines was not a wise choice, and Lifus finally understood why so many Chosen ones had died in just one month.

"This is a dust bomb to find invisible enemies." Green pointed to the screen and said, it was recorded by a team member who was on a combat mission at the time, in fact, each of these team members was recording their own battle video, and then uploaded it to the headquarters in real time, so that after the battle, they could analyze and summarize it through the video in order to formulate the next strategy and plan.

They can also record everything they see in their eyes through photon scanning templates directly into video files and store them in the brain hard drive, so that even if they are killed in battle, when people find their corpses, they can also take off the "black box" hard drive in their brains and obtain the invaluable video data of their lives in battle.

"The surface of these mechs can absorb light and detect rays, making it appear as if they don't exist." Hearing Greene say this, Livers remembered the peregrine falcon's previous guess.

The soldier in the video screen fired a bomb into the air, and with a dull explosion, a large cloud of black and gray smoke clouds spread out in mid-air, filling a large area of the battlefield, making the originally gray video even more gray.

Mass like a cloud of dust slowly descended from the sky for a very long time.

The mechs that were hidden in the air were quickly revealed: as they moved, they would crash into the dust suspended in mid-air, so that their path could be determined by the naked eye, but if they didn't move, the dust that was still falling would soon help them pile up a gray-black silhouette.

After firing the dust bomb, the warrior began to run desperately to the left, and in the distance there seemed to be a transparent mass moving rapidly, and it violently smashed through the dust along its way, like a hurricane. The warriors are in a figure-eight shape with its path, and if nothing else, they will meet at the apex, and it is clear that the Chosen One is very good, and he wants to complete the block in the mech's path of action.

"Boom!" A tactical nuclear bomb exploded not far away, and the Chosen One was already prostrate on the ground before the nuclear bomb exploded, and the picture was shaking all the time, the tremor of his running, and the tremor of the earth caused by the nuclear bomb.

Overwhelming dust poured down from above, and the picture suddenly went black, and it was obvious that the man was buried in the dust kicked up by the explosion.

However, he didn't let himself be buried alive for too long, and the dust that covered his body washed out again, but he seemed to have been injured a lot, the radiation suit on his body was broken, and he didn't run as fast as before.

He simply took off his radiation suit and helmet, threw away the oxygen cylinder, and pursued lightly.

About a hundred and fifty meters away from the transparent mass, he finally began to attack, and an EMP* was launched, and the tail of the bullet swallowed a hot tongue of fire, whistling forward, almost instantaneously reaching the mysterious transparent mass, but at this moment, a dense number of bullets were sent out from the transparent material, intercepting the EMP*, which exploded in the air and did not hit the mech.

The Chosen One, who had been ready for a desperate fight, did not stop attacking, and he fired a second EMP*, then a third, a fourth, a fifth......

* Exploded in the air one after another, not a single one hit the mech, however, a large number of electromagnetic bombs exploded in front of it, and finally caused some interference in its internal information transmission, it appeared a little sluggish, and then three EMP* hit it one after another, and it immediately stopped running like a scrapped machine in a factory, paralyzed there, and the invisible coating also failed, revealing a bulky body.

Lifus stared at the video screen closely, carefully observing this mecha in its original form, which was different from his imagination, and unlike the angular mecha that has always appeared in film, television and literary works, it was rounded, and it was not anthropomorphic at all, it had no head, no feet, no eyes and nose, in fact, if it weren't for the extremely long mechanical arm, this mecha would have looked like a perfect orthosphere.

"It can observe and shoot from any angle of this sphere, launch nuclear bombs, and this robotic arm can also be retracted back, it doesn't need wheels and tracks, it's a wheel itself." Green explained to Lifus again.

"Are we going to fight something like this? It's horrible. Lifus looked at the mechanical monsters in the video in shock, and they had no chance of winning a battle with these things.

"Don't be surprised, my friend." "There's something more terrifying to come," Green said, "so save more of your adjectives that you use to express horror and fear." ”

The video screen that was playing turned completely black after a burst of dazzling bright light, but unlike the last time the screen went black, this time it was the black screen after the video ended, and the Chosen One was hit by the crossfire of other mechs, and he died.

Green turned off the video, then found another video file in the folder and played it.
