0:00 on August 14, 1998

Four hours have passed since the search and rescue operation, but nothing has been obtained other than a more detailed map of the tunnels.

The number of gift boxes in this area has exceeded 100,000, which sounds like a lot, but in this vast mountain range, which can only do the work of scouts, the eight-legged walking device has been tested in this mountainous area, and the effect is very good.

But there is no result in the main thing, the keystroker is strong in vertical detection, but weak in wide-area detection, so it needs to be deployed a lot, and the manpower is insufficient, and the number of guides is insufficient, maybe there should be a mobile keystroker similar to a gift box drone, and Comrade ACU wrote down this need.

Comrade ACU was on the command seat of the command vehicle, staring at the map of the war zone, and on the other hand, there was something similar to a crystal rod in his left hand, just like a student turning a pen boringly in class, Comrade ACU was unconsciously playing with the crystal stick.

Gong Xuetu next to him looked frightened, ready to catch the crystal rod at any time Although the air conditioner was only 16 degrees, the sweat on Gong Xuetu's forehead was still oozing, just like a fat uncle. In fact, Gong Xuetu is not fat at all, his slender body and strong muscles all reflect that this product is a man, so why is he so empty?

It all started when he asked a little more an hour ago.

"Chief ACU, what is that crystal you turned in your hand, it looks pretty good." If Gong Xuetu was given a chance to go back to the past, he would definitely not ask such a thing.

"Oh, it's just an antimatter container, you like to give it to you," Comrade ACU said, while throwing this thing at Gong Xueha, but added later:

"There's two grams of antimatter in there, be careful not to hit it."

"Oh!" What? "Nani!" In less than 1 second, his face changed three times, and after getting it, he stuffed it back into ACU's hands like a hot potato

How powerful is 1 gram of antimatter? According to Gong Xuetu's understanding, if one gram of anti-material is completely destroyed, it can release 40 million tons of Nobel equivalent energy, and if it is two grams, this is a Tsar Bomba

But Comrade ACU never took this seriously, just played with it in his hands, and Gong Xuetu was shocked to watch it for an hour.

touched, the container fell to the control platform, and Gong Xuetu's heart was entangled at once, but Comrade ACU didn't react, picked it up and continued to turn.

Comrade ACU used his golden finger and exchanged a [material antimatter warhead] with 730 points in X3AP, which has an energy field in it, which will bind a certain amount of antimatter, and when the energy field is destroyed, the antimatter will lose its restraint and fall, and when it comes into contact with the surrounding matter, it will be extinguished, bursting out with powerful energy. After the completion of the huàn, the ACU returned to an empty state.

After the ACU is completed, it acquires the way in which the antimatter is made, at the moment of acquisition.

"Antimatter D-GUN Detected Coming Online"

The acquisition of antimatter has enabled all the functions of the ACU to be activated, so that the personal force has been improved to the extreme, and in the past few days, the protective shield and other equipment have been gradually upgraded, which is worthy of the trend of ACU comrades developing in the direction of superhumanization.

But this antimatter is of little use to the whole situation right now, because this thing can't always be loaded into ammunition, and it has no enmity with the Earth King.

After ACU arrived at the Sanshan defense line, Comrade ACU began to launch a ground offensive against BETA, Comrade ACU built 20, 152 multi-barrel rapid-fire guns, each with a rate of fire of 360 rounds per minute, to put it bluntly, it is a barrel of one second to shoot one shot, the gun is a Gatling wheel style, after firing a round of rotation cooling, the next barrel is fired, fully automatic chain loading, and the oversized Gatling was born.

20 non-stop shooting, how much ammunition can be projected into a place in one minute? If 360 shells are fired per gun in one minute, then 20 guns are 7,200 rounds, and according to the calculation of 50 kg of a 152-caliber projectile, 360 tons of mass are projectile per minute, and 21,600 tons in one hour, and Comrade ACU has been bombing continuously for 4 hours.

In 4 hours, ACU comrades fired 1,728,000 rounds of 152-caliber shells, weighing 86,400 tons. In the Okinawa Campaign that year, the US military only dropped more than 300,000 tons of ammunition, but in four hours, Comrade ACU fired out nearly one-third of the ammunition of the US Army in the Okinawa Campaign. This is just to look at the weight, if according to the power, the ACU of the metal hydrogen charge still needs to increase the Nobel equivalent by 30 times, and in the end, even the [Heavy Light Level] was beaten to the point that it needed to temporarily avoid the edge and retract into the tunnel. Hit the heavy light level panting, energy depleted.

And the engineering units of the whole fleet are rushing to work on the gift box and [F5U], and the number of our units is gradually surpassing the number of enemy units. If you add the footbasin defenders who are playing soy sauce everywhere, our forces in this area will have an advantage. The heavy light class was tired of dealing with the raindrops of 152 shells, and there was no time to take care of other units.

The beta on the ground gradually retreated back into the ground, and the underground beta made a hole out, and when trying to sneak attack, the action that had already been detected by the keystroker would inevitably be covered by 152 shells, and it continued to emerge to continue to cover, and the beta has learned to make holes in the anticline until now.

Knock ~ Knock ~ Knock ~ Knock ~ Suddenly there was a sound of sound waves tapping on the control platform, and a direction on the control platform was circled by a red circle.

"Near latitude 37 degrees 1 north and longitude 139 degrees 0 east longitude, audio tapping was found, and upon inspection it was a pulsed sound wave of the keystroker."

The voice of inorganic matter sounded on the control platform, which was a kind of synthetic prompt tone, and after seeing this prompt tone, Comrade ACU immediately became energetic.

One last look at that location, it's really a cheat. In the center of the Central Mountains, at an altitude of 2200 meters above sea level, the position is not very precise at the moment, and Comrade ACU has already ordered a large number of troops to rush where to go, conduct triangulation tests, and locate the target in detail, not too deep. Comrade ACU said silently.

Comrade ACU took Gong Xuetu and moved towards the target area, and at the same time, a large number of unmanned vehicles arrived in that area first.

"[Mothership class]?" At the time of the transfer, the ACU comrades received a war briefing from the rear, and the new [BETA] variety was named the [Mothership Class]. After deploying a large number of keystrokers in this area, it was discovered that some of the tunnels in the underground did react differently from the rest of the tunnels, which was the key to how quickly the Beta excavated the tunnels.

Hey, let's go to the quality extractor.

After all, humans are not rats, since the birth of human beings, this kind of thing is not too familiar, and the equipment that can be used in underground combat is also extremely limited, but the mass extractor is a thing that extracts mass from underground ore veins, in fact, anything can be extracted, and this equipment can dig holes vertically, up to the magma layer.

But this thing takes over the population

Soon dozens of T3 mass extractors were built, and the creation of zào and destruction of miè are actually the positive and negative sides of the same coin, and how much power there is to create zào has as much power as there is to destroy miè.

The T3 mass extractor was originally designed to extract underground mines, but when the drill bit of the extractor penetrated the bottom layer and penetrated the mothership-class that was digging below, the nano-solution was infused into the [mothership-class] body, which meant that it was ruined.

Dozens of [Mothership-class] struggled below, and the ground shook. But the time lasted for a short time, and it soon stopped, because these [Mothership Class] and the [BETA] below were dissolved into an unknown substance, which had no value to ACU, but it was still absorbed and decomposed, not only did not create anything for ACU, but also wasted a lot of energy.

The T3 mass extractor has a disadvantage, that is, this thing mainly covers vertically, and the area coverage is not wide enough, so [BETA] gradually changed its strategy and gradually began to bypass this device, and another round of cat and mouse game began.

The triangulation finally determined the location of the sound source, and Comrade ACU saw that it was 3,300 meters deep from the surface.

Comrade ACU sent the report to Comrade Gong Xuetu and sighed: "Hey~~~ It's so deep, it takes a long time to dig a pit." ”

After looking at the perimeter, even if you dig an inclined pit, it is not so easy, and the ACU comrades can only dig it with engineering vehicles.

----------------------- I am the dividing line of perspective transformation--------------------------

"What time is it?" Cui Yifei asked.

"According to the timer, it's currently 1:20 a.m. on August 13!"

One of the team members said.

"Comrades are holding on, there are still 40 minutes left before the shift change!"

"The eldest sister is fine, I can hold on!"

"It doesn't matter how many hours you last!"

"That's what you want! We must hold out until reinforcements arrive, and I am sure that the head of the ACU will not abandon us. ”

"Yes!"

The girls are fighting in turns, two squads fighting, and one squad resting, this is the established strategy.

While it was strange that there would be such a large amount of supplies in such a place, no one would be looking into these things at this time.

Although the team can take turns to rest, there are two people who have never rested, one is Cui Yifei, and the other is Ruan Fangdie.

Ruan Fangdie has been making mines, using some simple parts, to make a remote-controlled forklift, this forklift is carrying out minelaying operations, mines are very important to these girls, because if the [Assault Level] comes, mines are the only hope. But so far, Yiqiē is still smooth, the assault level has not appeared, and [BETA] has not dug a hole in the ground, BETA is really giving face. It was just a simple rush through the passage and then knocked down. There are more and more corpses of [BETA], and sometimes there will be a kind of [BETA] unit that has never been seen before to drag the corpses away. These units are small, numerous, but they don't rush up to attack. The girls have taken images of these units for intelligence analysis in the rear. This operation was an eye-opener, and there is still very little understanding of [BETA] among humans, which is the consensus of everyone, and more is needed in order to defeat [BETA].

"Big sister, it seems that [BETA] hasn't launched an offensive for a long time"

"That's right, big sister, it feels like there hasn't been a BETA for more than half an hour!"

"Ominous premonition!!"

"You crow's mouth! Shut it all up! ”

"Grasshopper 1 calls Summer Worm 1, according to the vibration felt by the detector, the number of BETA large species is about 30, and it is approaching us, according to the voiceprint detection, it is [Assault Level]!" Ruan Fangdie gave Captain Cui the final blow.

"Crow's beak, !!"

"Activate the alarm, call everyone up, we're in trouble."

According to the captain's order, the activation process began in the first type of mecha, waking up the members who were resting, and after a few seconds, all members entered the combat state.

The guards of the footbasin are already asleep, and they can be put to sleep by putting some sedative gas into the guò breathing apparatus, so don't wake them up at this time.

[Assault Grade], like cavalry, does not run all the time, but only enters the assault state when it gets close to the enemy, because this cargo runs in a straight line very fast, and if you keep running, no one will be able to catch up.

But at this time, everyone saw several assault classes crossing the passage unhurriedly, the huge front armor protected their weaknesses well in the cave, and the assault class also specially lowered their bodies, so that their legs could not be shot.

"Shoot!" With the order of the people, the electromagnetic guns began to fire with 20-mm armor-piercing shells.

[Assault Class] has slanted armor against the sky, which determines that any cannonball may be bounced off unless the force penetrates very much, but for the sake of flexibility, the mech is not equipped with a more powerful weapon.

But it's too late to say anything now, the BETA's assault class has already begun to charge, bang bang bang ~~~ The sound of the mine exploding, the mine worked, and the assault class was eliminated, but a group of small things soon followed, and the assault class was gnawed clean, and then when the body of the assault class disappeared, the second wave of the assault class followed

Wave after wave

Two waves

Three waves
