In one day, the stationmaster made a full ninety-four round-trips, bringing all the core carriers to the submarine base.

At first, he was able to bring back two people at a time, but soon he could only come one by one, and then the speed became slower and slower, and finally ten times he went back and forth, each time he had to lie on the ground and gasp for breath for a long time before he could get up.

When the last person was followed, the stationmaster's breath relaxed, and he was directly unconscious, and the oil girl Iron Pill hurriedly recruited a few working worms to send him into the treatment cabin.

The spaceship that had completed the mission quietly retreated, and the oil girl Tetsumaru cut off the connection with the main base and began to fight independently.

He assigned a lot of construction work to paratroopers and young core bearers, working hard to exploit the resources of the seabed.

In view of the inability to increase the production of organic matter in the deep sea, as well as the abundant manganese nodules on the seabed and the metal resources in the volcanoes, the design of the swarm was temporarily changed.

He used a large amount of metal to create part of the body of the worm, which reduced the amount of organic matter required by the worm, and tripled the production rate of the insect colony.

The structure of the newly expanded deep-sea brood is greatly simplified, and all unnecessary parts are removed, resulting in the new brood no longer having a complete appearance, and it looks like it is hollowed.

One side expands into the deep sea, and the other side spreads into the shallow sea, actively advancing towards the islands and continents in the ocean.

When the brood was established to the continental shelf at a depth of 600 meters, new movements were discovered by the six-stringed star intelligent machine, and drone bombing and space-based weapons strikes followed.

The oil girl Iron Pill had been prepared for this for a long time, and the lack of energy production caused him to be unable to deploy the electromagnetic water film shield, but there was still no problem with magnetizing the seawater.

When a metal weapon enters magnetized seawater, it cuts through the magnetic field to generate an electric current, and the explosives in the weapon are detonated prematurely due to electric shock.

Depth charges with good electromagnetic protection can only slowly descend at a rate of 5 to 10 centimeters per second due to the huge resistance generated by electromagnetic induction, and then are easily destroyed by the sound wave tower of the brood.

The more powerful space-based weapons are also unable to penetrate 600 meters of magnetized seawater, and even a tungsten rod that reaches a speed of 30 kilometers per second can only penetrate more than 160 meters, and then sink at a slow speed.

As a weapon of the "God retarded" type, this thing is a mass bullet, and it has no power after losing its speed, and the metal tungsten with such a high purity is a rare and precious resource, and there is no problem at all when used directly.

After this engagement, the oil girl Tetsumaru felt the depth of the attack of the six-stringed star, and then he continued to expand towards the shallower sea, until the water was only three hundred meters deep.

During this period, the six-stringed star persistently attacked by various methods, and even the ancient cavitated torpedo was taken out.

Don't say it, after the sudden use of the cavitation torpedo, it really caught the oil girl by surprise, and he lost two hollow broods.

However, the cavitating torpedo is not an invincible weapon, it is only capable of blowing a large number of bubbles in front of the fish, causing the torpedo to actually travel through the bubbles.

The cavitation not only eliminates the resistance of the water, but also causes the magnetic force in the seawater to be disturbed, which prevents the formation of stable electromagnetic resistance, so that the torpedo using a rocket engine can reach the speed of a propeller aircraft.

….

The biggest enemy of the cavitation torpedo is the lateral impact force, because the bubble is blown forward, and the side does not have the corresponding ability, once it is impacted, it will cause the torpedo to turn and lose the target.

The centrifugal force generated during a sharp turn is a test of the torpedo's solidity, not to mention the inevitable impact of the sea water that does not blow out blisters after turning.

A torpedo as fast as an airplane hits the sea, like an airplane that hits the surface of the sea, and is destroyed by a violent impact.

Oil Girl Tetsumaru has added a super magnetic field generator to the brood, using a series of magnetic field generators to make magnetized seawater flow, forming an artificial undercurrent.

When the cavitating torpedo enters the undercurrent, it will be turned by the impact of the side current, and then hit the side of the sea water headlong, and then start to roll violently, at most two turns, the torpedo will break into several sections, and various parts of the interior are scattered everywhere

。

Over the next ten days, the six-stringed star tried to release highly toxic, large-scale quicklime, salt and other substances to curb the expansion of the brood by changing the properties of local seawater, but it was obvious that it failed.

When a brand-new surface fleet came to this sea area, the oil girl Tetsumaru became excited, when your plane was high, I couldn't do anything about you, but I could let go of the ships floating on the water?

The fleet arrived in an attempt to build a large electromagnetic generator and compete with the brood for control of the magnetized seawater.

If you can successfully establish your own magnetic field system, you can speed up and slow down the currents in the entire sea area, and the swarm of insects that are enough to toss will not be able to develop with peace of mind.

As night came, the counterattack of the oil girl Iron Pill also followed, and he did not mobilize a large-scale swarm at all, but commanded five Pompeii insects entrenched in the deep sea.

Each of the five Pompeii worms carried a mushroom worm on their backs, and slowly rose to a depth of about 100 meters near the surface of the sea.

The Pompey Worms coordinated each other's positions, and the four on the periphery formed a square with a side length of two kilometers, framing the entire fleet, and the Pompeii Worm in the center moved slightly upward, and then the five Mushroom Worms detonated at the same time.

Five huge white mushroom clouds towered over the sea, and the whole sea was choppy, but there was no shadow of a ship anymore, and the Six-String Star Wisdom never made any surface ships again.

The next day, hundreds of nuclear bombs were dropped on the ring in retaliation, creating hundreds of huge mushroom clouds on the sea, but they were insignificant to the swarm hiding in the deep sea, and the brood at a depth of more than two thousand meters did not feel the slightest abnormality.

In response, the oil girl Tetsumaru launched more than 2,000 explosive locusts to launch a counterattack on the orbiting star ring, but all of them were shot down by the enemy.

The oil girl Iron Pill had a gloomy face: "The Heaven Control Power is really not so easy to break, I'm afraid that you have to drop millions of locusts at the same time to break through the enemy's defense limit, and this exchange ratio is too much of a loss."

The stationmaster was already very happy, the oil girl Iron Pill was worthy of being the leader of civilization, and this shot was much stronger than himself.

Relying on the existing forces and brood, he successfully turned defense into offense, firmly grasped the initiative in his hands, and led the nose of the intelligent machine.

In these six days, the back and forth with the enemy bought a stable time for the stationmaster, Ash Bone, Sanae Uchiha, Hachiki Sakushige, and the core taker, and the construction of the submarine brood expanded rapidly, ten times greater than the previous stationmaster's two-month results.

….

But the most annoying thing about mechanical intelligence is that they really won't give up, and they repeatedly compete with the swarm of oil girl iron pills in the sea less than a thousand meters deep, and keep dropping all kinds of strange things when the attack doesn't go well, especially some kind of carbon molecule flocculent.

This flocculent is non-toxic, but it can greatly increase the viscosity of seawater, resulting in a decrease in the light transmittance of seawater, and the crooked hitting is turning the 100-meter seabed into a completely lightless area, and the fungus blanket laid by the oil girl iron pill in the shallow sea area has become useless.

Due to the lack of photosynthesis, the yield of organic matter is extremely low, which is the biggest bottleneck limiting the development of insect colonies.

On the fifteenth day, the Six-String Star Machines discovered the situation, and they stopped stocking the flocculent and instead produced a large number of black ocean balls, which were released on a large scale in the shallow sea, and these ocean balls floated on the ocean, and the shading efficiency was higher than that of the flocculents.

And the ocean balls are more difficult to clean up, because they are floating on the surface of the sea, unlike flocculents that can be filtered in deeper water, and octopus insects can only rise to the surface to clean up these pesky ocean balls. br/>

The clean-up process will inevitably expose itself, inviting precision bombing by drones.

And don't look at the ocean ball is not big, but it is very difficult to deal with the round, and it must be pinched flat one by one in order to chop and compress, and the process is quite troublesome.

Before an octopus insect is killed, it can clean up to a few hundred ocean balls.

Although the production cost of one octopus worm is not high, the cost of producing hundreds of ocean balls is even lower, so it is very uneconomical to exchange them.

Oil Girl Iron Pill commissioned Ash Bone to develop a bacterium to the sea

The material of the ocean ball is food, and the efficiency of the cleaned ocean ball is immediately satisfying.

A few hours later, the material of the ocean ball produced by Zhiji was fine-tuned, and there was an extra layer of film on the surface that was inedible for bacteria.

The two sides launched an all-round confrontation around the ocean light, and the result was that the intelligence machine had the advantage, so that the organic matter production gap of the swarm could not be solved, and then suppressed the expansion rate of the swarm.

Of course, no matter how large the amount of ocean balls produced, it has no effect when it reaches the rough deep sea, because the waves will destroy these light balls, and the fierce currents will drive the ocean balls somewhere to pile up instead of allowing them to be spread flat across the surface of the sea.

But the deep sea itself is enough to block all the sunlight, and the oil girl Iron Pill can't take advantage of this vast and unobstructed sea.

Until one day, Sanae Uchiha found the oil girl Tetsumaruna and showed him a test tube filled with green algae.

Knowing that Sanae was in charge of the deep ocean trench, she shouldn't have access to this sea surface algae, so he asked, "Sanae, where did you get it?"

Sanae pointed in the direction she was responsible for and replied, "I also discovered it by accident when it was scraped off the shell of the brood."

The oil girl Tetsumaru took the test tube, and easily confirmed that it was indeed green algae through insight, and he praised the Uchiha girl loudly, "Excellent, Sanae, you have done me a great favor."

Sanae Uchiha was dressed in a colonization costume and couldn't see her expression, but the giggles still gave an idea of how happy she was.

….

"Oilgirl-sensier, can I ask for a reward?"

"No problem, just say what you want."

"Ah, great, when it's time to attack, please let me be the vanguard, the first to attack!"

"What? I've only been working for a few days and you're getting impatient?"

"Well...... I'm not bothered! I, I just want to fight, yes, that's it, I haven't had a good fight in a long time."

"Okay, yes, I'm okay."

Sending off Sanae Uchiha, Oilo Tetsumaru begins to investigate the source of the seaweed.

Chlorella on the surface of the sea appears in the deep sea, which was absolutely non-existent before this, only because the currents created by the electromagnetic field caused the convection of the sea water up and down, bringing the green algae on the surface of the sea down.

It didn't take long for Yau Tetsumaru to find the Descending Current, a waterfall in the sea that is a submerged zone of water that stretches for more than a hundred kilometers.

Because it stirs up the underwater current, it brings a strong reverse surface current, and when this cold-water current encounters another warm, low-salt current, it is squeezed into a downward cascade of currents.

At the same time, he also found a rising ocean current in an undersea mountain range thousands of kilometers away, which is the ocean current that forms the upper and lower convection.

Oil Girl Iron Pill breathed a sigh of relief, with this ocean current, he can filter seaweed from the ocean and obtain organic matter, although the quantity cannot fully meet his needs, but after all, it is a large piece of resource supplement, and the bottleneck that restricts himself is a little faster.

Just as the oil girl Tetsumaru was leading a group of young people to add a filter officer to the hollowed-out brood, a flash of inspiration suddenly flashed in his mind.

[Why do I need to filter this inefficient filtered seaweed, and why does the fungus blanket have to be a layer?] 】

The fungus blanket was originally a fungus mass composed of a variety of fungi, and it didn't take much effort to transform it into a fungal mass that was invisible to the naked eye, and then released it into the sea water on a large scale, allowing these invisible fungus blankets to float away along the ocean current.

The seawater mixed with the fungus blanket fungus reaches the surface of the sea through the rising current, receives full sunlight, rapidly multiplies and uses photosynthesis to produce organic matter, and then returns to the bottom of the sea through a waterfall, returning to the released brood after forty-five days.

The controllability of the mushroom blanket is much easier than that of the green algae, and the oil girl iron pill easily isolates a large amount of organic matter and energy from the fungus blanket fungus.

A fungus blanket dissolved in seawater has appeared across thousands of kilometers, and this ocean is the new fungus blanket

The bottleneck of the development of insect swarms has finally been broken.

This was followed by an explosive expansion of the swarm, with the mother nest spreading across the ocean like mushrooms after rain, and large-scale bugs being produced.

The abundance of energy has made more and more seawater magnetized, and the construction of magnetized water electromagnetic railguns, as well as the construction of electromagnetic water film protective shields, are constantly increasing.

The deep-sea area, which occupies nearly forty percent of the area of the six-stringed star, is rapidly armed, and the conditions for controlling the planet to launch a counterattack are initially met.

Before a large-scale counterattack, Yau Tetsumaru launched a series of tentative attacks.

In addition to continuously launching third-generation high-speed explosive locusts into space, he also sent swarms to land on some islands and continents to test the reaction of the intelligent machines.

The swarm that landed on the island was simply bombed by the air force, and when the swarm retreated, it pursued all the way to a depth of 300 meters and stopped attacking.

However, the insect swarm that tried to land on the continent was like stabbing a hornet's nest, causing an unprecedented violent reaction from the Six-String Star Intelligent Machine.

Space-based bombing, airdrop bombing, space-based laser irradiation, and even the most unsuitable god retardation were all thrown away, and all six insect swarms were wiped out in the shallow sea, and not a single insect could touch the shore.

Stunned, he couldn't understand the enemy's violent reaction at all, it didn't follow the logic, and he asked the stationmaster, "What's on land?" Makes the six-stringed star's intelligence so nervous."
