The stars, but they become the gray wind

"You want me to use the Tianyan Star Ring to predict the possible future direction of human civilization on your side?" In the control core of the Tianyan Star Ring, Aze was floating above the surface of a dodecahedron with gravity facing oppositely, and was communicating remotely with Kalisi, who was planning to scatter the ashes of the Earth Cult assassin in a physical sense in a few days.

"Yes, it is possible, but... this process may result in a certain amount of error."

"Just tell me how accurate it is, right?"

"72.45 percent, and the highest won't exceed 80 percent. In short, this accuracy is definitely not high.")

"That's almost enough."

"However, since the Tianyan Star Ring doesn't fix a civilization's future trajectory like a closed time-curve computer, its accuracy in predicting a civilization's possible future trajectory must be at least 90% to be sufficiently accurate."

"If the accuracy is less than 80%, there may be situations where the process and results differ significantly from the calculated ones."

"Although there will be considerable differences in the process and results, overall it still follows the rough route calculated, right?"

"That's correct, but all the details involved will be completely inaccurate, and we can only provide a rough and vague picture of the process. As for the results, there will be a considerable degree of deviation without violating the essential conclusion."

"From my perspective... if they could know a possible future for themselves, even if the details were vague and the conclusion could only provide a rough outline, it would already be beyond their reach."

"You want them to try?"

"Ah."

"Then I must remind you of one thing. If it's something too close to their present, and they're heading towards an uncertain future, the Evolutionary Ring can only give a rough and vague picture of the process."

"But if they want to calculate a distant point in the future that has nothing to do with them, then the Tianyan Xinghuan can counterintuitively eliminate the influence of their individual disturbances and provide accurate calculations and deductions of scenes in the distant future that have nothing to do with them."

"It's just that... because the time they calculated is so far away, the future on that scale has nothing to do with them. There's no way to interfere with it from such a distance. If that's a particularly bad outcome, then anything they do now or in their lifetime will be useless."

"Because the time scale is too far apart, the butterfly effect caused in the past is not enough to have a big enough impact in the too distant future?"

"That's right. If it's a relatively good, acceptable future, then it won't have much of an impact on them. But if it's a disastrous outcome, then for those of us who happen to be at that critical position and time point, to say they'll suffer a lifetime of pain is the least of our worries."

"Then how about I show them my other future? The original one."

"After all, what is good and what is bad is determined by comparison. If they see the worst possible outcome, will they still think other outcomes are worse?"

"Like those little creatures in Kara Kuja, perhaps in the future they will consider whether our direct assistance and enlightenment is the best option. But no matter how bad this option is, it is better than them gradually forgetting their original intentions after tens of thousands of years of evolution and development, eventually becoming brutal, tyrannical, warlike, and short-sighted, allowing their civilization and planet to be destroyed in the flames of nuclear war, and eventually turning their once vibrant home planet into a desolate and silent desert planet."

Explain why the spacecraft in this book uses gamma-ray lasers, which seem to be very primitive and crude weapons:

Gamma rays are high-energy particle streams that exist at the quantum scale.

From an objective point of view, the nucleus of any atom can block a gamma ray particle 100% if it collides head-on with a high-energy particle in the gamma ray.

You can imagine it as rows of sparse but irregular small balls with large gaps between them. Gamma rays are like small balls rushing over at high speed. When they hit other small balls, they are blocked. If they don't hit them, they penetrate. When a bunch of small balls come over, there will always be some that hit them, and there will definitely be some that don't. As for whether they will hit or not, only probability theory can tell.

The principle is that simple.

So how can we completely block gamma rays? The simplest solution is to put as many layers of blocking balls as possible to make it thicker and reduce the chance of gamma rays passing through, rather than using materials that look very solid to block them.

Next, let's look at the total gamma-ray flux energy spectrum and the cross-section of its effect on the human body. Gamma rays cover a wide energy range, from MeV to TeV and even EeV. Rays with excessively high energies have a very small cross-section and pass through the body without leaving a trace. The most lethal rays are usually in the MeV range.

To put it simply, the reaction cross section can be thought of as the probability of a reaction. I've never seen a 100% probability, so generally, some radiation passes through the supersolid, and some of it interacts with the human body. If there's too much interaction, the person dies. Gamma-ray bursts are so powerful that even a slight leak can overwhelm the human body and cause immediate death.

Normally, nuclear fusion produces gamma rays, hard X-rays, and neutrons below 1 MeV.

The current laws of physics themselves indicate that even strongly interacting materials will be shattered once they are hit by gamma rays exceeding 100MeV. Under the action of gamma rays at the 100MeV level, neutrons will separate from neutrons, and protons will also separate from neutrons. When the energy level of gamma rays exceeds 1900MeV (equivalent to 1.9GeV), even the surface composed of truly neutron-degenerate matter will be directly peeled off. Even truly absolutely smooth neutron-degenerate matter will be directly penetrated when it comes into contact with gamma rays with energy levels and output power that are too high.

Most of the gamma rays that humans can currently produce are gamma-ray photons of around 1MeV from nuclear fusion (nuclear weapons). Although they are all gamma rays, the energy level of photons at the 1MeV level is so low that even supersolid matter such as electron degenerate states cannot cause any effective damage to them.

假设功率能达到太阳等级的G2V黄矮星恒星1%功率，能级2GeV（2000MeV）以上的伽马射线激光束，就算被打击对象使用中子简并态物质作为对定向能武器的防护手段，也会在恒星1%功率级别的高达2000MeV以上的伽马射线激光命中后被瞬间烧穿。

Chapter 251 Kara Kuja's Dyson Cloud

The assassin who was lucky enough to survive from Kalisi was quickly carried away on a stretcher by several allied guards present. Yang Weili looked at the piles of ashes on the ground with lingering fear. Maybe he should listen to Schinkob's advice, practice his shooting skills more, and carry a pistol with him?

"You really should carry a sidearm. Sometimes, the enemy isn't just tens of thousands of kilometers or even light-seconds away in space; they could appear right next to you in unexpected places. A sidearm can really save your life at certain critical moments."

"Is that so? Is this also the conclusion you came to from observing our future?"

"You can imagine this kind of thing without even observing it."

"So...as you mentioned earlier, do you want to know what your future holds?"

"We may be able to point you in the right direction, although this path is fraught with considerable uncertainty."

"We can also show you another possibility based on what has already happened. By changing the past and the future, you might be able to try a new path. So... are you two interested?"

"What do you mean?" Siegfried asked from the side.

"If you are loyal to a certain party or faction, or if you are curious about the future of human society, then come to the Void Gate System in two months. We can provide you with an answer that you will need to explore on your own."

"We have a way to deduce the future of your human civilization without determining your future, and calculate another past that has not happened."

With the navigation capabilities of the Alliance and the Empire, it would take more than half a month to reach the star field near the Iserlohn Corridor where the Void is located from the core circle of both capitals. Kaleesi left them ample time for consideration and preparation.

"We won't wait until later, but before that, you two or any other part of humanity can come. We will provide them with an opportunity to know the possibilities of their future."

"So... if you had the chance to know your future, even if it was just a possibility that hadn't been fully determined, would you reject it?"

"Then... what is the price?" asked Yang Weili, who knew that there is no free lunch in the world.

"The price is no price. You will know the possibility of stomach cancer, but there is no specific method to achieve the result and possibility you want. You can only try to get this result on your own."

"Well, Siegfried Gilfias, Yang Weili, and Julian Mintz, if you want to know, please come here in two months. We will be waiting for those who have lost their way."

A wormhole portal shaped like a water wave appeared behind Kalisi. After leaving these words, Kalisi and all the drones present disappeared into the closing entrance of the micro wormhole. The only evidence that she had been here was the ashes and black carbon atom powder that had been decomposed into atoms and had not been cleaned up on the ground in time.

The body of a creature hit by a Gaussian fission ray will be torn apart at the atomic bond level and turned into a pile of black carbon atoms. Of course, if the creature hit is a silicon-based creature, the product left after the target is decomposed will be a pile of silicon atoms.

"I didn't realize you were good at close combat?" Yuuki teased Kaleesi, who returned to the Void Gate System from Iserlohn Fortress in just a few seconds.

"I only have a limited understanding of close combat. As for chopping off that guy's hand, it's purely because our pure nanomechanical aggregate life form's nerve and body reaction speed is at least thousands of times faster than humans.

Even the fastest human reaction speed is around 100 milliseconds. Even a battle-hardened figure like Senkob, who was by Yang Weili's side, could only reach that limit. But us... even a Sky Alien, whose body hadn't undergone any modifications, could easily achieve a nerve and muscle reaction speed of under 0.1 milliseconds, which is just average. This level of reaction speed is something we sisters could achieve with an unmodified body, let alone us."

"As long as the reaction speed is fast enough, the assassin's movements of drawing the gun and shooting are almost like slow motion to me. It's too slow. And don't blame me for this kind of thing. You can easily perform the same operation."

"However... for both us and the sisters from Sky Star, any close combat skills seem insignificant, even a bit redundant."

"Their development environment and status from ancient times to the present day have made close combat techniques completely useless, except for a small number of sisters who study it as an art form."

"As for the human need to research such things due to war and conflict, it has never existed or appeared in Sky Star society. From the beginning to the end, close combat techniques have been nothing more than a hobby similar to art in Sky Star society."

"After entering the era of more advanced interstellar civilization, this kind of thing is even more unnecessary. Close combat skills are of no help in interstellar warfare."

"We don't need to consider, and there won't be, any infantry boarding battles to capture enemy ships or space stations."

"However... as long as your reaction speed is fast enough, your strength is strong enough, and your technology level is high enough, no matter how powerful the opponent's fighting skills are, they will be defeated in an instant."

"As for that assassin... I felt it necessary to take the most intimidating approach." Kalisi pulled out the single-molecule dagger hidden behind her back. The tip of the blade was made of a layer of strong interaction material that was only a single molecule thick and was almost absolutely smooth, while the blade was a wedge-shaped blade with a thickness of 1 cm. The blade, made of a strong interaction material that was only a single molecule thick, could cut through any material connected by conventional chemical bonds as easily as cutting paper. Even when faced with supersolid materials such as metallic hydrogen or electronically degenerate materials, this specially made single-molecule knife could easily cut through them.

"Most of the time, this thing can only be used as a decoration. As for its practical use, it has almost no practical use."

"Not necessarily? Maybe you could try using it to cut vegetables?"

"what?"

"Remember Nina? It seems they like to use single-molecule cutting tools to occasionally create some high-precision artistic sculptures."

"It is said that the raw materials are obtained from local heavy metal asteroids. Then, single-molecule cutting tools are used to cut asteroids and meteorites that are about the same size as you into suitable shapes for sculpture."

"According to Nina, laser cutting is more likely to damage the asteroid and meteorite raw materials. Using a single-molecule cutting tool to cut the sculpture raw materials is more convenient and more regular."

"We definitely don't have that kind of artistic talent, but we can use it to chop vegetables."

"Why do you feel a little bit earthy?"

"Why don't you go and learn from Nina and Noshalin how to use a monomolecular knife to carve out suitable sculpting materials?"

"I really can't learn the kind of carving they do..." Carlisle silently put the single-molecule dagger in her hand back into the scabbard.

"Lord Reinhardt, this is the detailed account of what happened at the scene." Gilfias told Reinhardt in detail about the accident that occurred at the prisoner exchange ceremony, using the surveillance video taken by a body camera carried by a soldier at the scene.

"Earth Religion? I've only heard of them before. I always thought they were just a bunch of ordinary religious believers. I never thought they had such a huge influence behind them."

"Yes, this is the evidence she gave to me and our ally, Admiral Yang, about the actions of the Earth Cult." Gilfias took out a data storage device from his pocket and handed it to Reinhardt.

"I've examined the relevant evidence, including evidence of Earth's involvement in human trafficking, illegal drug and narcotics smuggling, weapons possession, murder, kidnapping and extortion, financial fraud, involvement in the bribery of many important military and political figures in the Empire and the Alliance, terrorist attacks, and suspected training and gathering of large numbers of illegal armed forces in recent decades."

"It seems like these guys are really guilty of heinous crimes!"

"Yes, Lord Reinhardt. The details of many of these crimes are simply horrifying. There is no doubt that the Earth Religion is nothing more than a cult. We must take action against this unscrupulous cult as soon as possible."

"I will let Kesla take charge of this matter and quickly clear out and eliminate the Earth Cult strongholds and those involved in the case within the empire."

"Also, Lord Reinhard..."

"I understand. Was it the alien lady's active invitation?"

"I didn't believe in such vague things as destiny or fate before, but... after that incident, maybe they really can know our future."

"But, maybe we can't refuse at all?"

"?"

"She said that whether it's the one from the alliance or us, as long as we go to that system before the specified time, they will provide answers to the visitors."

"Then suppose we don't go, but our ally does and learns about our own future and the future of human society. Although, as the alien lady said, it might be difficult for him to have a significant impact on this future, Gilfias, don't forget that information advantage is paramount, whether in war or politics."

"If we simply refuse to believe in superstitions like destiny or fate, and don't proactively gain information advantages, we might be left behind in future competition."

"So, I think I might have to go anyway."

"What's more, I'm also curious about the possibility of another future that the alien lady mentioned before."

"If this kind of future can really be calculated, then future humans can do the same. We might be able to take our destiny into our own hands."

Compared to Reinhardt, who holds great power and can freely decide his own actions, Yang Weili is not so free.

In war and politics, the party with information advantage can often gain the upper hand and even easily win. Yang Weili has understood this truth since his student days in military academy.

The alien lady had made what could clearly be called an active invitation, but as the commander of Iserlohn Fortress, Yang could not leave his post at any time. In response to the alien lady's invitation, Yang decided to send a letter to the Alliance Military Department and the Provisional Parliament in the rear. In this letter, Yang explained in detail to Bikgu and Xitler, who were currently senior members of the Alliance Military Department, and Jessica, Lebelo, Hewang and other key members of the Alliance Provisional Parliament, how he met the alien lady, including the records of the hundreds of fleet simulation battles conducted by both sides on computers, the advanced technology that the civilization behind the alien lady possessed to observe and predict the future, the importance of her invitation to the Alliance, etc. The letter explained and emphasized in great detail, hoping that the Alliance would approve his application to temporarily leave Iserlohn Fortress.

At the same time, the information in the data storage device that recorded the numerous crimes of the Earth Church, which was thrown to Julian by Kalisi, was also sent back along with this letter. Yang checked the evidence of the crimes of the Earth Church recorded in this data storage device. He had always vaguely felt that Feisha, who was caught between the Empire and the Alliance, had always had some unreasonable and strange goals and logic in his actions. However, Yang could never find an explanation for Feisha's seemingly unreasonable actions and strangeness. After seeing the information hidden by Feisha and the Earth Church in this data storage device, Yang Weili suddenly realized that these evidences strengthened the connection between Feisha and the Earth Church. For a long time, the Earth Church had been secretly intervening in and manipulating the politics of the Alliance and the Empire through Feisha, a puppet driven by economic and financial interests. Like an invisible mold, it was deeply embedded in the Alliance and the Empire through Feisha's invisible big hand.

The files in this storage device also revealed an incredible number of allied military-industrial enterprises and political lobbying groups that were connected to and had a lot of interests with Feisha. Feisha firmly controlled the handles of a large number of political officials within the alliance through bribery and interests. Many funds and resources with unknown whereabouts eventually flowed into the pockets of Feisha and these corrupt elements.

And corruption is even just the lightest crime in this document. In order to cover up these crimes, the termites within the alliance, the Earth Cult, Feisha, officials protect each other, and officials collude with businessmen to form a huge spider web composed of money and connections. The considerable number of missing people, suicides and murders without punishment in recent years within the alliance are just the tip of the iceberg of these termites trying to cover up their crimes.

Regarding the contents revealed in this document, Yang Weili found that this was no longer a problem that he or several senior military officials could handle. He sent the document privately to Jessica, Lebelo, He Wang and others through an encrypted communication frequency band, and explained the source of the document.

After finishing the application letter and related explanations, which were incredibly long for Yang, Yang Weili breathed a sigh of relief and planned to go eat something to relax. Sometimes knowing the truth can be very painful. The Alliance, the Empire, Feisha, the Earth Church, those dark sides that were intertwined in the shameful dark corners made Yang Weili feel under great pressure. Before this series of events, the Alliance, the Empire, and Feisha, under the prosperous and glamorous surface, could be said to be rotten to the core.

Yang stretched himself. Those things were not something that a mere commander of Iserlohn Fortress and the admiral of the 13th Fleet could worry about. If he wanted to eradicate the corruption that was deep-rooted, he could only rely on the conscience and sense of responsibility of the people of the alliance.

Walking into the restaurant, Yang was surprised to see a small group of people headed by Senkob gathered around a table, exclaiming from time to time.

As Yang got closer, he realized that the people gathered around the table seemed to be members of the Rose Knights under Senkob. As a marine corps specializing in ground combat, every soldier in the Rose Knights was tall and strong, and was proficient in fighting skills and the use of firearms. What surprised Yang the most was that Julian was also among the large number of Rose Knights.

"Ah, Admiral Yang, you are here for lunch too?" Xiankobu greeted Yang.

"What happened that brought so many members of the Order of the Rose together?"

"It's about the assassination attempt you suffered at the prisoner exchange ceremony a few days ago. Afterwards, I checked the surveillance footage of that hangar and found something interesting."

"Something interesting?"

Schneider, Julian, and some of the Rose Knights stepped aside, allowing Yang to see what they were surrounding. It was a holographic video player, showing the surveillance footage of the assassination on the day of the prisoner exchange ceremony. However, the footage Schneider played seemed to show everyone in slow motion.

"Is this slow motion?"

"Yes, I've always been curious about where that alien lady came from, so I checked the footage captured by all the surveillance cameras in the hangar at that time, and then... I discovered something surprising."

"That incredibly powerful alien lady came out from a dark corner. Coincidentally, there was a camera facing that corner, and it captured the entire process of the alien lady's attack."

In the picture, a gun with a luminous green light appeared from the shadows along with its user. As the green beam shot out, an electric arc appeared at the muzzle. Then, Sinkob switched the view to another camera. The assassin from Earth was about to make a final struggle and tried to shoot Yang Weili. The image of the alien lady seemed to flicker and turned into a blurred afterimage. Then, the next moment, the assassin's arm holding the gun flew out with blood splattering.

"What's wrong with this part?" Yang asked curiously.

"No problem...it's just that the alien lady rushed towards the assassin and swung the knife so fast. Not only was it so fast that I couldn't see it clearly, even the high-speed camera couldn't capture it clearly. How did she do it?"

"Admiral, as you know, the commander of my Rose Knights has always been confident in his reaction speed and close combat skills, but this..." Senkob pointed at Carissa on the screen.

"If I were to face this guy, I probably wouldn't be able to survive even one move."

"I asked the management sergeant in the monitoring room to break the video down frame by frame and slow it down over 1000 times so that I could see the entire process clearly."

Sinkob operated the player twice and switched to the same video played at 1000 times the speed.

In the picture, the purple-haired girl reacted at the same moment the assassin's hand reached for the pistol hidden in his coat. With a speed that seemed unbelievable to humans, she leaped to the assassin's side, pulled out the dagger hidden behind her back, and cut off the assassin's arm that had just raised the gun.

"Less than 0.1 milliseconds... This is the result we obtained after repeated analysis and calculations." A member of the Rose Knights with rich combat experience said solemnly.

"Even with the assistance of power armor, we can't react in such a short time."
