wandering planet

Rouge.

Samuel was looking at the star map.From Faust's imminent return course to where the Rouget was, there was nothing in the way.

"Basil, move the Rouge a little further," said Samuel, "closer."

The deputy captain rejected his request: "Samuel, if we go any further, the Rouget will be completely out of the instant communication range of the Marseille ground port. This is very bad for us."

Samuel thought for a moment, then gave up.

He sat in the captain's chair and looked at the people in the cockpit.

The cockpit of a military ship is several times larger than that of a civilian ship, and there are naturally more people inside.The Rouge is currently not performing military missions, it generally only patrols in or around the Alpha system.Marseille Surface Port contacted Samuel immediately after noticing that the Rouget had started to move away from its patrol route.

Samuel didn't hide it either, he directly told the people at the ground port: "I'm going to pick up my wife and go home."

Everyone in the ground port control room knew that Faust was back and that Bering was on board.However, a military ship like the Luge must not leave its position casually. What's more, the Luge is equipped with a large number of weapons and advanced survey equipment. Once it leaves, the situation will become extremely serious at any time.

In the control room, Samuel's junior snatched the communicator: "Captain Samuel! Please don't worry, we have already contacted General Lee Swright! The general's order will come down immediately! Come back!"

Samuel heard it, but he pretended not to hear it.

Whether what the junior said is true or not, he is thousands of miles away, so it cannot be verified.Taking a step back, even if General Lee Swright is contacted, what if the general disagrees?What if the general thinks that Faust has been missing for 30 years and his whereabouts are suspicious, so he can't let him return to Marseille immediately?Faust is now near the Sirius planet belt, where the situation is complicated, and Samuel thinks that he can't wait like this.

Besides, Bering was on board.

His wife, who had been missing for 30 years, was healthy and safe on that ship.

The subspace transition was successfully completed.Communications between the Rouget and the surface port of Marseilles began to experience delays.

The junior was furious, grabbed the communicator and kept talking: "Samuel! Senior! You still have time to come back! Especially since there is an anti-aircraft gun on the Luge, like you... people in the fleet are easy to think of!"

Samuel asked him: "Where will I go? Am I a traitor? Am I going to join the enemy? Or am I going to counterattack Marseilles with anti-aircraft guns and these weapons?"

The younger generation was speechless.

"I'll be back soon." Samuel said calmly. "I don't care if I go to review or get fired. Bering is right in front, and you want me to wait in the back without asking? Impossible. "

Communication with the surface port is temporarily cut off.Samuel leaned back in the chair and let out a long sigh of relief.

It was all his crew on the Rouget who he felt sorry for.

When they learned that Faust was back and that the captain's wife Bering was also on Faust, all the crew members in the cockpit cheered excitedly.This good news immediately spread throughout the ship along with the internal communication network of the Luge.This is a ship that Samuel has managed for nearly 40 years. Every crew member on the ship was brought out by him. Everyone knows how their captain searched for Bering in vain for 30 years, but failed. Never gave up.

So when Samuel asked everyone "Can I pick her up", no one raised any objections.The deputy captain even encouraged him: "I can take the responsibility with you. We only have one request: please be sure to introduce us to Madam."

After all, Bering was also an excellent captain in the Marseille fleet, not to mention that in the past 30 years, they had heard Samuel mention his beautiful and brave wife countless times.

"Basil, contact Faust." Samuel completely relaxed, "How long will it take for Bering and the others to arrive here?"

"About 10 minutes." The deputy captain sent a communication request to Faust.

Thirty seconds later, everyone in the cockpit of the Luge heard the exclamation of Deputy Captain Faust.

——"There are obstacles!"

Linney stumbled over from the back cabin.He had just slept in the aft locker with the blindfold still around his neck.

"What's the matter with the obstacle?" He paled and hurriedly sat in front of the console, "Cosmic garbage?"

Since the communication between Faust and the lifeboat has been connected, everyone on the lifeboat heard the sound from Faust's cockpit.

Jiang Che and Ovid both thought of the huge mass of cosmic garbage.Pierre's face also changed: "Yes... I know what it is... That piece of garbage is half the size of Faust! Faust's current speed is simply impossible to avoid!"

Faust will collide with that cosmic junk, like two planets colliding in space.They smash into each other, explode, and eventually disappear into the universe.

Everyone on Faust will be turned into dust in the universe.

Linney grabbed the control handle.

"Pierre, let's go back." He said quickly, "Ovid, help me and Pierre, we are now driving the lifeboat back, and count as much as it can hold. Jiang Che, Tang Mo, go to the back cabin to count For a moment, if there is anything that can be thrown away, throw it away immediately to make room for people to pick up..."

"No, Linney." Bering's voice came from the loudspeaker.

"Don't talk nonsense!" Linney yelled, "If you can't get anyone... If you can't get anyone, Pierre and the others can go back to Faust, and I will drive the lifeboat to hit that thing! I can knock it away Yes, now there must be an external force..."

Bering was very calm, as if what they were facing was just an ordinary thing, as if the end of dying had never happened: "It's too late, Linney. It will take at least 10 minutes for you to return here, but we are only 2 minutes away from the garbage of the universe. Less than [-] minutes."

Lin Ni clenched the control handle tightly and opened his mouth, unable to utter a word.

Bering's voice was very clear, as if the person was right in front of them.

"Linnie, don't think about death all the time. You have to love yourself more. You are very important, very very important... No matter to anyone, your existence is important." Bering said gently, "I can recognize you." You and Cicero are very happy things for me. May you reach the Black Sea safely and reach your destination safely, no matter...whether you return to Marseilles or go to Earth..."

At this moment, Pierre yelled: "Empty the gun!!!"

He couldn't help standing up.

"Captain Bering!" he yelled at the top of his voice, "There are evacuation guns on the Luge!!!"

The anti-aircraft gun is a fixed-point defense gun developed by the Marseille fleet. It was originally only installed on the ground. In order to increase the defense capabilities of military ships, the fleet has studied for decades before developing a small anti-aircraft gun that can be mounted on military ships.

Evacuation guns do not need to capture the target on the radar, as long as the target location is determined, it can carry out extremely precise fixed-point strikes.

It is difficult to locate stars in space through clear data such as latitude and longitude. In order to be able to grasp the situation of the surrounding star field, Marseille has launched tens of thousands of navigation satellites in more than 500 years.According to the principle of three-point positioning (*), as long as the three navigation satellites capture the clump of cosmic junk, the precise location of the clump of junk can be given immediately, and the emptying gun can launch an attack.

After the successful development of the anti-aircraft guns that can be carried by military ships, the Luge is the first batch of military ships that perform patrol missions to be loaded.

Bering also remembered this incident. At that time, she was still arguing with Samuel, and she failed to sign a divorce agreement several times.

But the evacuation gun cannot be fired.

In the absence of an order from a superior, once a weapon is used, there is no room for recovery.

This is a tough choice.

If the Rouget fires its evacuation guns and smashes up the rubbish, everyone on Faust will be safe and return safely-but Samuel will not only be subject to censorship, he will also go to court-martial, and In the worst case, the entire crew of the Rouge will go to court.

If the Luge abandons the emptying gun, Faust will hit the space junk in 2 minutes, and everyone on the ship will die, or float out of the cabin, becoming a cold corpse in the universe, or burning up After that, it turned into invisible dust.

Bering did not let Samuel make the choice, she made the choice first.

Faust has been full of twists and turns since it set sail.First, it entered the 118 route by mistake during the transition, and then was captured by the gravity of the galaxy's nuclear bulb, unable to break free.After returning to the correct route, important information was lost due to 30 years of time, which made it impossible to reach the Black Sea and return to Marseille.

Faust seemed destined to be destroyed.Instead of being destroyed at the nucleus of the galaxy, it will be destroyed here at last.

Bering sat on the chair, and everyone in the cockpit silently watched the iron-gray solid that was getting closer and closer on the screen.

"Leather rice..." Bering said suddenly, "Am I doing this right?"

They've cut off communications with the Rouget.Bering was unwilling to let the voices of himself and Faust's last moment remain in Samuel's heart.

Leather rice did not respond.It was him who was at fault, the one who violated the rules and drank alcohol at work.

"Bering?" Samuel's voice came out suddenly, "Do you hear my voice? Faust doesn't need to turn..."

"Samuel..." Bering interrupted him, "I love you."

Samuel paused for a moment, then said gently: "I know. But don't say it now. I want you to stand in front of me and tell me directly."

Bering laughed, his nose tightened due to the strong astringency.

[Warning—Warning—too close to the obstacle, too close to the obstacle...]

In Faust's cockpit, they could already see the distorted porthole on the cosmic junk.

"Communication from the Luge! Communication frequency from the Luge! Give it to me!" Linney yelled at Pierre, "I'll contact Samuel! Tell him to open the evacuation gun!"

"Can't get in touch!" Pierre cried, "Sorry! Can't get in touch! Our equipment can't connect to the communication frequency of military ships! We can only connect to ground stations and civilian ships..."

Linney threw Pierre away.

Behind the lifeboat, they could see a small dot of white light moving from a distance.

That's Faust, like a speck of dust in this boundless universe.

Communication was suddenly cut off.

In the silent lifeboat, they all saw the light from the mote.

It seemed to explode, and a tiny, tiny flame spread out in the dark universe, and then went out immediately.

Linney lay prone on the porthole, with a hoarse and muddy moan from his throat.

It's all so sudden, from Faust saying they've run into an obstacle to now, it's all too fast.

Pierre stood behind the crowd, as if he couldn't bear it, he suddenly burst into tears.

Along with his cries came the sound of a small green light on the console.

The beep sounded monotonously, and it was heart-pounding to hear in the ears.

It was Ovid who reacted first.He stepped over the crying Pierre, staggered to the console and switched on the communicator.

"Faust, Faust!" Because of shock and ecstasy, his voice changed, "It's Faust!!!"

What exploded in the universe was not Faust but the hard steel garbage.

Bering and everyone in the cockpit were stunned.Less than 10 kilometers away from Faust, the huge mass of cosmic garbage suddenly exploded without warning, as if being ignited inside.

The tiny amount of oxygen inside burned up after the explosion, and was quickly extinguished as it burned out.

Cosmic junk made of iron flakes, rocks, and dust disintegrated silently in the universe.

Due to the vibration, Faust lost communication for more than ten seconds, but soon after the explosion ended, it was in contact with the lifeboat and the Luge again.

Samuel's voice was steady and powerful: "Bering? Didn't you fall?"

Faust passed through the pyrotechnics and shattered steel fragments, got out from the thin smoke, and finally saw the Luge floating far ahead.

Like other military ships on Marseilles, the Rouget looks ordinary, but the front muzzle has not been retracted, revealing a dark round hole.

In Faust's cockpit, everyone was speechless.

Knowing the consequences, the captain of the Luge activated the evacuation gun.

"You are crazy!" Bering grabbed the microphone and yelled, "Samuel! You are crazy! You are destroying the future of all the crew of the Luge..."

"They are very supportive of me," Samuel continued. "Don't be angry, they want to know you very much."

Bering was speechless.But after a moment of bewilderment, she quickly adjusted herself.The emptying guns have been activated, which means that the people at the ground port of Marseilles have received news that the Rouge has used heavyweight weapons without authorization.Together with the Rouge, she faces what is about to happen.

"Wake up the passengers! Wake up!" Bering sent a message to Faust's crew, "Faust is about to approach the Luge and enter the interior of the Luge's cabin. All crew members strictly observe their posts and get ready. "

Pimi's hands were still shaking: "I want to drink...I really want to drink now..."

Bering punched him: "Don't think about it!"

The whole ship became chaotic.People came out of the room and looked around.Everyone could feel the shock just now, and many people pulled the crew to ask what happened.Heaney from the logistics department was running in the cabin, and he found that his subordinate Jiang Che was missing.

"We are safe!" The crew blushed with excitement. Compared with the passengers who knew nothing, they all knew what had just happened. "The military ship in Marseille saved us! We can go home!"

Some passengers who wanted to go to the earth showed disappointment after hearing that Faust was really going back to Marseille.But knowing that they can enter military ships that ordinary people cannot enter, many people are still full of curiosity.

Passing through the curious and excited crowd, Bering finally felt the security of being alive.

She doesn't see the curiosity and excitement as inappropriate.She even hoped that all passengers would not have any worries or uneasiness, although excitement is fine.Originally, the civilian ship Faust left Marseille for travel, which should have been a fun and enjoyable trip.

"Captain! We are approaching the Rouget." The deputy captain told her through the communicator, "Captain Samuel said he is waiting for you at the entrance!"

"Know!" Bering began to run towards the exit of Faust.

In fact, she herself had never been on the Luge, and she was also full of curiosity about what kind of ship Samuel worked on.

While running through the corridor, Bering stopped suddenly, turned his head and took a look at himself in the mirror.

The mirror in the corridor was too small, and only Bering's face and upper body could be seen.She looked at the young woman in the mirror, thought for a while, then turned and continued running towards the exit.

It's just that as she ran, she parted and tousled her hair and wiped off her lipstick.

This is a bit embarrassing, but what she wants is embarrassment.

On the Rouge, Samuel was also nervously asking the deputy captain: "Basil, do I look bad?"

The deputy captain was a middle-aged man. He looked Samuel up and down: "Captain, it's not bad, you are perfect."

Samuel's hair was half gray and combed back neatly.His uniform is also new and sharp: he just received an award last year, so the fleet made him a new uniform.On his left chest was the same orange graduation badge as Bering, and the Phoenix showed a gentle arc in the light.

"Really?" Samuel was skeptical. "White hair makes me look too old... Basil, is there any hair dye?"

The deputy captain pointed to the warning sign on the wall: "Hair dye is flammable and cannot be brought on board the ship. Captain, you are very nice and handsome, trust me."

Samuel: "Okay."

He was still tense, and his heart was beating hard beneath the badge on his left breast.

The Luge opened the hatch entrance. Its volume was several times larger than that of Faust. Faust carefully drilled into the hatch and stopped smoothly at the bottom of the Luge.

This cabin is used to house the battleship. After Faust calmed down, the passengers stood by the porthole and looked curiously at everything inside the Luge.Countless battleships were neatly arranged inside the Luge, and they vacated a small space for Faust.

Samuel was standing at the entrance of the cabin.He tugged at his uniform, and the next moment he saw Faust open the hatch.

Bering stood in the hatch panting.Her hair was disheveled, her face was pale, there was no trace of blood on her lips, and she looked very embarrassed and haggard.

Samuel immediately forgot about whether he looked too old or not.He took a few steps and wanted to say something, but all the words were crowded in his throat, making him choke.He opened his arms towards Bering.

Bering thought he could control it, but he couldn't hold back his tears when he saw Samuel.

Samuel knew what she was like when she was young, and they watched each other grow up together - but she never imagined what Samuel would look like at 60 years old.

Perhaps in previous conversations, they all talked about each other's twilight years.But that is by no means what it is now: she is still young, and there are still decades ahead of her to live slowly and tastefully.But her Samuel was out of time.

She couldn't wait for the slide of the cabin door to come down, and jumped off Faust directly, throwing herself into Samuel's arms.

Samuel leaned down and kissed her hair just as he had hugged her before. "You haven't taken good care of yourself," he whispered. "You don't look well."

Bering grabbed his uniform and laughed while crying: "You are still handsome."

Samuel frowned, but a smile appeared on the corner of his mouth.Bering was familiar with his expression. Even though he was 30 years old and his face was covered with wrinkles, she immediately knew the meaning of Samuel's expression: it was helpless and full of love.

He stroked Bering's hair lightly, watching his crew board Faust one after another, leading the passengers on Faust down.

"It's like a dream," he whispered. "Honey, I've been dreaming all day today."

Bering wiped his tears on his uniform, and finally remembered that he was going to scold him: "Yeah, you are dreaming! You actually activated the emptying cannon just like that!"

"Hmm..." Samuel spoke in a trance as if in a dream, "I'm going to court-martial."

He can't think normally now.In the 30 years he spent in Marseilles without Bering, he imagined many scenes of reuniting with Bering, but none of them was as urgent and frightening as today.Samuel felt as if all his life's wishes had been fulfilled on this day. He didn't know what to do or what to say for a while, so he could only hug Bering tightly in his arms and repeat a sentence: "Go to court martial..."

Bering stroked his face, and Samuel showed a slightly painful and ashamed expression: "I'm old."

He finally showed a trace of hesitation and fragility in front of Bering: "Bering, what should we do in the future?"

Bering didn't hesitate at all: "Let's go together."

"Go...where?"

"Court-martial, let's go together." Bering looked at Samuel with firm eyes, and his tone was equally firm, "I will go to the court-martial with you. We can justify this matter."

For this problem, Samuel is not particularly worried.He is about to retire, and this is his personal behavior. In order to leave the other crew members on the Rouge aside, he and the deputy captain have made full preparations, and all the decisions and actual operations in the voyage file , will only display Samuel's name.

"And after court-martial?" he asked Bering.

"Then go home," Bering said, "let's go home.... You haven't changed the lock, have you? It's been so long, is the lock broken? You have to give me a new key..."

Samuel kissed Bering's forehead, feeling an indescribable tenderness in his heart.The coming disaster seems to be far away from him, and he and his lover are drifting in the vast universe, with no obstacles and no end.

"No change." He wiped away Bering's tears, and replied softly, "I know you have the house key with you, so you dare not change it."

After Faust entered the Rouget, he shut down the communication frequency of the ship itself, and has lost contact with the lifeboat since then.

Linney sat blankly in front of the console, looking at the various data displayed on the screen.Out of sight of them all, the Rouge began to return with Faust.

"The evacuation gun is not a gun, but a heat ray, so the target will explode from the center!" Pierre was very excited, with tears on his face, but he was already talking about the weapons on the military ship with great excitement Equipment, "In addition to the emptying gun, there should be..."

Ovid stopped him: "Stop talking."

Pierre: "Can't you say it? It's not a secret either."

"No one listens to you." Ovid looked at Pierre with pity, "Poor boy... your audience is only me, but I don't want to know these things."

Tang Mo took a bunch of snacks from the back cabin to eat, while Jiang Che sat in front of the console and tried to contact the Black Sea transfer station again.Linney was the weirdest, since he knew that Faust was safe and sound, he had been sitting there without saying a word.

Pierre stared at Ovid: "Ovid, will you listen to me?"

"Not interested." Ovid showed him the orange badge Bering gave him, "Tell me first, how can I make a hole in the badge like Linney, and then make it into a pendant? I tried Several tools are useless, what kind of material is this made of? It’s so hard.”

Pierre took the orange badge, with unconcealed envy in his eyes: "That's great, Captain Bering actually gave you this."

Ovid wanted to say, "Don't you have it too", but when he looked up, he found that although the badge worn by Pierre was the same style, it was blue.This is the sign of an ordinary graduate, he bowed his head and stopped talking, picked up an awl and kept looking.

"These tools are useless." Pierre said, "The emblem is made of a special cosmic alloy, and it is impossible for ordinary tools and ordinary temperatures to damage it."

Ovid: "Oh..."

He suddenly remembered Linney's badge.The badge that he hung around his neck was obviously burnt.

"Unless it is affected by extremely high temperatures in the universe." Pierre continued, "There will be burnt marks on the badge, and the material will soften slightly, allowing holes to be punched."

Ovid glanced at the back of Linney's head and lowered his voice: "Then under what circumstances will you be affected by the extremely high temperature?"

"Either it entered the energy circle of the star, or the magma erupted." Pierre thought for a while, and suddenly thought of the explosion they saw just now, "Oh, by the way, the explosion and combustion of the ship will also produce extremely high temperature .”

Linney stood up suddenly.

Ovid and the others were taken aback, because Linney's expression was terrible, as if he was suppressing great anger, but also seemed to be full of humiliation.

He strode past Ovid and headed straight for the back cabin.

Ovid was dumbfounded, seeing Jiang Che looking back at him, he quickly pointed at Lin Ni's back: "He, he is so rude! He actually stepped over me like this..."

Jiang Che: "Because you and Pierre happened to block the door."

Ovid looked at the narrow cab door and fell silent.

Jiang Che tried several times but couldn't contact Heihai. He guessed it was because they came without warning and Lin Ni cut off the communication roughly, so Song Junxing didn't want to talk to them anymore.

Faust had returned to Marseilles with the Rouget, and after the shock of grief and joy, he developed a strange sense of weariness.

Tang Mo opened the white-cut pork knuckle that Ovid brought up, and was discovered by Ovid when there were only two pieces left.The two started arguing, Jiang Che stared blankly at them arguing, and suddenly felt hungry.

"I'm going to get something to eat," he asked Pierre. "What would you like to eat?"

"Cookies," Pierre said. "Sandwich crackers."

A lot of food and drinking water were stored in the back cabin, when Jiang Che walked in, there was a sudden crisp sound under his feet, which startled him.

An orange badge on a bronze-colored chain fell at his feet, with scorched markings on it.

Jiang Che picked up the badge, looked up and saw Lin Ni was lying on the box in the back cabin, covering his eyes with his hands.

"Linney..." He wanted to return the badge to Linney, but was scolded and ran away by Linney's brusque "Get out".

Jiang Che put the badge on the cardboard box and didn't intend to pay attention to this grumpy young man.It's just that when he walked past Lin Ni, he saw the scar on Lin Ni's palm.It was the circular mark left by the cigarette butt pressed directly on the skin.

Jiang Che found the biscuit.This is a kind of sandwich soda cake that sells well in Marseilles. The sandwich is a kind of green sugar sauce.He has little interest in oddly colored food, so he continues to bend over to find something he can eat.When he stood up with a few packs of jerky, Linney had already left.But he didn't take the badge away, as if he didn't know it was with him, so he didn't find it.

The orange badge was hanging on the side of the carton, Jiang Che thought for a while, and put it into his pocket.

While sleeping, Jiang Che and Ovid had a disagreement.

"There are many rooms on the ship, and there are also many sleeping bags." Jiang Che stopped Ovid from his door, "You sleep by yourself."

Ovid was surprised and dismayed: "We've always slept together."

Jiang Che thought for a while: "Then let's sleep separately from today."

Tang Mo ate a pack of fruit jelly, grinning and passing behind Ovid, winking at Jiang Che.

Ovid blocked Jiang Che's door: "Jiang, I'm used to sleeping with you, I can't sleep well alone."

"Don't worry." Jiang Che said gently, "You try first, if you really can't sleep well, come here."

Ovid was dubious, turned and left.Jiang Che immediately locked the door to prevent the possibility of food thieves entering the room.

He didn't bother to think about what Ovid meant, since he didn't mean anything himself.

Ovid wailed outside Jiang Che's gate for a while, and was chased away by Lin Ni.Jiang Che fell asleep for a while, and suddenly heard a series of running sounds from outside the door.

That was not Ovid, who walked and ran very softly.Jiang Che sat up all of a sudden: It won't be Pierre, Pierre will be on duty with Tang Mo in the cab today.

He opened the door and saw Linney's figure disappearing into the entrance of the back cabin.

When Jiang Che walked into the back cabin, he saw Lin Ni messing up the cardboard boxes and looking for things on the ground.

"Are you looking for this?" Jiang Che asked him.

As soon as he loosened his fingers, a chain dropped from his palm, and the orange badge fell on the chain, shaking non-stop.

Linney got up immediately and snatched the badge from him.

"Don't throw it away." Jiang Che scratched his head, sat on the cardboard box and yawned.

Linney put the chain around his neck.There was a thin layer of sweat on his forehead, and he seemed to have lost his sleepiness, so he simply found a cardboard box in the back cabin and sat down like Jiang Che.

Jiang Che waited patiently until Lin Ni finally spoke.

"Did you hear what Pierre said today?"

Jiang Che nodded: "Understood. Has your badge been subjected to extreme heat?"

Lin Ni looked at Jiang Che, as if he was considering whether he should tell him what was on his mind.

"This is not my badge." After a long time, Linney finally said, "It belongs to my brother Cicero."

He didn't graduate from the academy, so he didn't even get a normal badge.

"Your brother must be very good." Jiang Che remembered what Bering and Lin Ni said before leaving Faust, "Captain Bering also said he was very good."

"Very, very good." Linney clutched the orange badge. "He's the best guy I've ever met."

After a moment, he let go of his hand.

"But he's dead." Linney looked indifferently at the small porthole on the back cabin wall. "He sailed a battleship, and then the battleship exploded. This badge is the only thing left."

Jiang Che was silent for a moment, unable to find the right words to comfort him, he could only say: "Congratulations."

"He committed suicide." Linney did not express his thanks, and continued on his own. "He is also a general, a fleet general younger than me. It is a terrible thing for a general to commit suicide by driving a battleship. Going to court-martial."

Jiang Che scratched his chin.Another court martial?

"But he can't go." Linney bent down, which made him look tired and sad, "I will go instead of him."

The author has something to say: the principle of three-point positioning is my nonsense, but it is actually an extension of three-point positioning.The author is a science scumbag, algebra related is bad but geometry is not bad... I just think that if three points form a plane, then in the triangular plane formed by these three points, as long as the distance between the three points and A is known, Then the coordinates of A can be known.After consulting the data, I found that there is indeed a saying that "only three pulsars can locate a certain star in the universe", so it is used here.
