The ultimate weapon, the Star Magnetic Circuit, has wiped out thousands of armies.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The light of the rainbow star shimmered on the dark starry background, and the Abyssal Star, like all other planets, looked like a beautiful jewel in the universe from space, slowly rotating in eternal silence.

Xinglan watched this scene quietly in space, not thinking much about it, but had a faint feeling of calm. She loved the feeling of staring directly at the objects in front of her in space, with no starships or asteroids around, only signalsons too illusory to be perceived by most creatures hovering ghostly in the vacuum.

She wasn't born on a planet, and although the stellar fury of energy gave birth to her, she felt like she belonged to the universe, and she felt like her home in this silent world, and she could keep it for a long time if necessary...... Or even hundreds of millions of years.

She has seen planets born from countless fragments, and has also witnessed the destruction of living planets and civilizations, and this protracted racial war on the Abyss Star is just a drop in the ocean in the entire universe, but the persistent spirit of life itself cannot be easily ignored. She'd been here, she'd seen it all, and had even caught a glimpse of the apparition twenty thousand years later, but she still felt lost now, she didn't know what else she could do.

The information about the source spores that she wanted to obtain had actually been successfully obtained from the central brain after a short negotiation, in fact, the people of Tianyuan did not attach as much importance to this information as she imagined, because the most fundamental key point of the information on how to guide the source spores was still the source spores themselves, and the Tianyuan Star was ...... There are no more source spores, and the last wisps of source spores have been wiped out in the war.

Although the planet has not been transformed into a planet fortress, its interior has been implanted with countless criss-crossing magnetic field guidance devices, and these devices were on the surface of the planet at that time...... Later, hundreds of so-called nodes were formed in the underground ocean. Through the location of these nodes, crystal creatures have found a way to roughly control those internal devices, and they have built dozens of deep-sea fortresses capable of withstanding the enormous water pressure, which, as long as they are in the position of the nodes, can resonate with the inner framework of the planet, thus guiding them to release some kind of power inside the planet...... That is, the originally scattered geomagnetic field is released.

It sounds incredible, but it's not impossible. The essence of the planetary magnetic field is generated by the high-speed flow of liquid metal inside the planet, as long as the activity state of the internal metal flow can be accurately calculated, and the state of this giant magnetic field can be controlled by intervening in the most reasonable way. Of course, it wouldn't have been that much trouble for the Ascenders to do this, but the crystalline creatures could only barely do it with the framework they had left behind...... This was obviously not the original purpose of the framework, it was supposed to be some kind of planetary environmental fixture, but according to the usual style of the Ascenders, that is, those low-level devices did not even have any permission encryption practices, and even crystalline creatures could barely intervene.

A super electromagnetic pulse that erupts by directing the planet's magnetic field is the essence of a planetary weapon called the planetary magnetic circuit.

The deep sea fortress where the central brain encountered by Xinglan is a star magnetic loop control hub that was captured by the people of the Abyss, this device does not require a complicated process, in fact, this imperfect system can be directly activated from any node, just like a lever that anyone can use there, only one node needs to be mastered, and this extremely powerful system can be mobilized.

Or at least until the Abyssal people rebelled.

The crystalline creatures have long since created these deep-sea fortresses for activation, but they have never actually activated this ultimate weapon...... The destructive power of the planetary magnetic circuit is too powerful to be contained, and once this imperfect device is activated, even the overflowing energy can produce a devastating catastrophe, so they will not really activate this terrible system at all. However, when faced with the choice between certain death and a glimmer of life, the people of the Abyss resolutely activated this planetary weapon after forcibly occupying a deep-sea fortress.

The planetary magnetic field, it is ubiquitous, so weak that only a small magnetic needle floating on the surface of the water or on the tip of a needle can feel this ubiquitous force, but it is definitely not weak, when this evenly distributed force in a huge space is confined to a small range, it is definitely not an electromagnetic pulse in the general sense. Xinglan saw that scene in the memory of the central brain, the moment the star magnetic circuit was activated, the entire planet's sky was covered by aurora belts.

The guidance device made by crystal biology was not perfect, so the activation of the star magnetic loop actually lasted only about thirty seconds...... However, this seemingly short period of time completely changed the entire battle situation of Tianyuan Star. After the extremely high radiation surface on the spot swept 360 degrees in an instant, all the space vehicles in the near orbit were all blown apart as if they had been hit by a super solar storm at close range. The thousands of mechanical legions of crystalline creatures were powerless to resist this pulse, and their circuit chips burned out from internal overload in the blink of an eye, turning into a pile of scrap metal.

More than 95% of Tianyuan Star's electronic products were burned in that short period of more than thirty seconds, and only a few remained. Even the creatures were not spared this level of attack, and more than half of the people of the Abyss died on the spot due to nervous system disorders, and most of the rest were also seriously injured. In contrast, crystalline organisms, which are silicon-based structures themselves, are much more vulnerable, with three-quarters of the population dying instantly.

This is the reason why crystal creatures have never dared to really launch this weapon, it is an extinction weapon for civilizations that do not have the ability to completely break away from their home planet, and the star magnetic circuit is not only this kind of large-scale pulse sweeping, it can even focus the magnetic field to a certain extent, and the Tianyuan people have used this function in several of the most important places of crystal creatures. Some camera installations recorded the scene from a distance...... Within seconds, a dense cloud of lightning appeared in the sky, and then converged into a dazzling hydrogen phenomenon. The light of the bomb exploded, and the matter several kilometers away from the focal point was completely ionized, and even the ethereal air was ionized by this force.

This is a real annihilation, unlike nuclear weapons that can be intercepted remotely, the star magnetic circuit is a weapon that cannot be intercepted at all, and can instantly attack any location near the entire planet from the ionosphere and lava layer, and its continuous range of influence may not be as large as that of nuclear weapons, but the destruction effect in a small area is more complete, and it will even destroy everything in a short period of time to form a spherical vacuum with a diameter of several kilometers.

The wreckage of the original body and the last source spores were completely wiped out in such an attack...... This was a painful choice for the people of Tianyuan. Their genes are locked by crystal biousable source spores, and they even lose their most basic ability to heal themselves, and have to rely on so-called visual therapy. The bell must be tied to the bell, and the gene lock made with the source spores must also be unlocked again with the source spores, but the crystal organisms have a strict degree of custody of the source spores to the point that they are completely unobtainable, so in the process of affecting the future potential of the race and being destroyed by the crystal creatures in a short period of time, the central brains unanimously chose the former and made a choice that can continue the race.

Destroyed source spores can be recovered from other places, but unless they find traces of source spores again in the vast universe, they will always struggle to survive in the shadow of this genetic lock.

The astromagnetic circuit was imperfect, so the system that had been built at countless costs only lasted for more than thirty seconds before collapsing, and the auroral bands that filled the entire planet's sky gradually dissipated, but the pattern of the world has changed...... The surviving crystal creatures and the Abyssal people were pulled to a close starting line, and they began to work to restore the technology of destruction, and after the two sides recovered a little, the unforgettable hatred once again erupted into a bloody war.

In fact, it may be a blessing in misfortune that this broken system only lasted for more than thirty seconds before collapsing, and if the star-magnetic circuit had been running for a longer period of time, the energy repercussions from those attacks would have ionized the atmosphere in a larger area, and even completely exploded the energy inside the planet to every corner of the surface, so that the surface temperature could rise to thousands of degrees Celsius in a short period of time...... At that point, it's definitely not a matter of not being able to continue living on the planet, and even spacecraft won't be able to get close to the planet.

In the research materials of crystal organisms, an ideal blueprint can also be found in their design. It is a remote-sensing satellite-magnetic loop, which will be greatly reduced in size, and can even be fully carried by a starship with a length of about 10,000 meters, and it does not need to be set up in advance inside the planet. The device, known as the Ideal State Star Magnetic Circuit, could even directly guide the eruption of a planet with a magnetic field in outer space, using this concentrated pulse as a powerful weapon of cosmic warfare...... The downside is that the planet's ecology will even be permanently destroyed.

Theoretically, it works, but in reality they don't have the ability to make it.

After knowing the truth, Xinglan lost her previous interest in this planetary weapon, because this device was too chicken, and she wouldn't want to play such an extinction on Lanxing, but the hundreds of nodes in the underground ocean made her feel very familiar, just like ...... Planets distributed in the Star Gateway.

Probably an illusion, the two are too far apart from each other, and they don't look like they were written by the same civilization.

This trip didn't seem like there was anything superfluous, she didn't plan to meddle in the struggle between the two races, but she didn't plan to leave a trace completely like the previous trips...... In fact, most of those times were forced to leave, but the Abyss Star was different, the technology here could not threaten her, after clearly knowing that the Abyss Star would become such a glorious civilization in the future, she naturally planned to see if she could obtain more technology in their development.

At this time, there are not many doubts left, and there are no more valuable clues to be found here about why the Ascender civilization left in a hurry and how the future probe traveled through time, and these are not problems that can be solved in a short time.

Xinglan looked at the rainbow star again, especially the star that shimmered green, she had already seen the complex machinery wrapped in force fields in the depths of the star, they had been running for hundreds of millions of years, and it was the most spectacular trace left by the boarder.

Perhaps, it's time to go home, Arashi.

……

Eh, wait, doesn't it seem like you've forgotten something very important?
