Finally, Ivan said in a relaxed voice: "Everyone, we are now out of Jupiter's rings and rocky and icey areas, hold on for dozens of hours, and after we are far away from Jupiter's moons, we can go with peace of mind according to the predetermined route, hard work everyone." Radarman: "Commander-in-chief, a new situation has been discovered, two objects are approaching us about 20,000 kilometers below our left. "Look at their tracks and figure out how to circumvent them." Ivan commanded. Radar officer: "I don't think the trajectory is like a meteorite or something, now add infrared scanning radar to see." "What is it?" Ivan stared at the radarman's side face. Radarman: "Wait a little longer." Ten seconds later, the radarman: "Hmm! Infrared scans show that the heat symptoms are obvious, and it is an internal heat stove, and there should be a heat flow from the tail of the artificial aircraft next to it, so it should be a man-made flying object, and the distance between the two objects is only a few tens of kilometers. Ivan: "Are we the closest to Europa now?" Radarman: "Yes." Ivan: "Before we know what they're coming from, let's hide behind Europa." Drivers are guided by radar to accelerate and head to the upper right of Europa. Duo Fan seemed to understand something, and untied the insurance on his body. He said to Zhaoli with a calm face, "Come with me." Zhao Li followed the small cabin where the two monitors were confined. After entering, he grabbed the collar of the fat man's clothes many times. "It's the security department you informed." Bai Min grinned: "What, they're here?" Whatever you want, let me go, you two, let me go now, and let you turn yourself in, and I will say good things for you, and they will not punish you severely. He let go of his hand many times, and raised his right hand again and slapped Bai Min's face. Fart, the result is still unknown, so dare to say big things here. "The boss who has stared at him many times." What can you do but get caught?! Bai Min tilted his head to prevent being beaten again, and his mouth kept nagging, trying to persuade them many times: "I have been monitoring you, that day, a few days before I didn't drink, in the back cabin, when I wanted to check the following of your goods, I heard movement from your goods. I also know you're going to have a big move coming soon, and that's to get out of that Stered cargo ship, hehe! So I informed headquarters. Zhaoli looked at it many times: "It seems that this guy also has eyeliner from Ji Ruide." "Probably!" Say it many times: "Do you think you can be saved when they come?" Bai Min: "The company has two armed ships cruising in space at any time. It's an armed ship, and it's equipped with missiles, lasers, and particle weapons! Can you handle this civilian ship? "Don't scare me," he slapped Bai Min's face with the back of his hand many times: "I'm annoyed, throw you two overboard, let you join the team of Saturn's rings by the way, and you will only be with stones and ice forever." Bai Min knew that this was giving him a way to die, so he didn't dare to speak, and rolled his eyes many times. Knowing the reason, the two of them returned to the command cockpit and explained to Ivan what they had just learned from Bai Min. "It seems that the comer is indeed not good!" Ivan sneered: "Hmph! I'll play with them and see whose ship is more advanced, huh! "They're armed ships, and they're armed." "Don't be afraid, I hope you don't be afraid, I still have confidence in my ship against their old ships in my opinion." Ivan said to everyone: "The radar officer cheers up the spirit of 12 points, pays attention to the radar screen, reports any situation found in time, and the driver pays attention to listen to my instructions and makes timely actions." Correspondent: "Commander-in-chief, there is an external voice signal, do you want to access it?" "Aren't we already hiding behind Jupiter's moons, what?" Zhao Li asked puzzled. Ivan: "Maybe we didn't hide it, or maybe the satellite was too small and the wireless signal was diffracted through." "Take it in." Ivan to the correspondent. An unfamiliar and threatening voice sounded in the buzzer: "Listen, whoever you are, come near us now, your ship will be taken over by us, don't resist and don't try to escape, it's useless." Give you a minute to think about it, and hear it clearly, a minute. Ivan into the microphone: "I'm the captain, we're the company's ship." Buzzer: "Which department." Ivan: "Equipment Department." Buzzer: "The same, must be checked." Buzzer: "Please approach us immediately." Ivan's helpless voice: "Okay, we are close to you, please turn on the indicator light, and when we get closer, please open the hatch docking system to guide us." Ivan: "Correspondent, turn off the external signal." Correspondent: "Yes, it's off." One or two scientists couldn't hold back their emotions and shouted, "What do they want to do!" Thinking that we are still bullies like before, we can do whatever we want! One said: "We don't follow his wishes, see what he can do to us, eat me?" Radarman: "Two objects may have spotted us, one on the top left and one on the bottom right, circling Callista and approaching us. Ivan: "The pilot listened to my command and approached the spacecraft in the upper left at a constant speed of 500 kilometers. The voice of the driver difference: "Approaching them?" Ivan said unquestionably: "Do as I say!" The driver reluctantly: "Yes!" Move closer to the top left. Ivan: "Radarman, report every fifty kilometers." Radarman: "It's three hundred and fifty kilometers now." Four or five minutes later, the radar officer: "Three hundred kilometers." ”

Radarman: "One hundred kilometers." Ivan: "Ten kilometers once." Radarman: "Ninety kilometers." Ivan: "Report once in a hundred meters." Radarman: "Nine hundred meters." Radarman: "Three hundred meters." Ivan: "Okay, the driver starts adding two hundred meters per second, accelerates away from its tail, and the engine starts the second second, and the second second is also ready. Ivan was not long behind in his voice, and the sound of the engine, which was previously indistinct, was now noticeably louder. Originally, Ivan had been uncomfortable since he said that he was close to the other party's spaceship, and several times, Duofan and Zhaoli wanted to ask Ivan why he was close to their spaceship? Seeing that he was very busy, he had to stop talking. As soon as they accelerated at this moment, they also knew a rough idea. But to deal with the opponent's armed ship, and let Zhao Li - I am afraid that many times too, his heart tightened again. As can be seen from the radar, the size of the armed ship is not small. It had been past the stern of the armed ship for a while, and the other party had not made any movement, probably because he did not expect the ship to suddenly accelerate under its nose and escape from behind the tail of his armed boat. They knew that the task of completely getting rid of the armed ship was daunting, and the entire cockpit knew that. Sure enough, it didn't take long for the radarman to remind: "After the enemy ship behind turns, accelerate and chase us." Ivan: "From 20,000 to 40,000 per hour, let's speed up behind Callisto, and then use Callisto's cover to move towards Callisto." Driver: "Yes." The driver's voice did not completely fall, and the radar officer: "There is an attack." "On the radar, a bright light grazed the ship, but fortunately the ship was accelerating and moving sideways, otherwise, the strong laser beam might have hit their ship. Ivan: "Accelerate to 60,000 per hour and do a curve maneuver." A few hours later, they hid behind Ganymede. Ivan: "Can't stay now, driver, move to Callisto at 60,000 mph." Radarman, how long will it take. Radarman: "About twenty-one hours." "You've arrived at Europa. Radarman: "The enemy ships are spaced apart from each other and fanning towards me. Ivan: "With Europa, move behind Europa." Radarman, how long will it take" Radarman: "About fourteen hours. Before he could fully hide behind Ganymede, radarman: "The enemy ship is still approaching." Ivan: "It's quite tight!" The driver we went around Callisto, well, I mentioned moving towards Callisto at 60,000 per hour. How long does it take for a radar officer. Radarman: "About sixteen hours." "Back behind Ganymede. Ivan: "Radarman, the enemy ships are not following." Radarman: "Didn't keep up." Ivan: "This is also temporary. We've estimated a hundred and fifty hours since we left the transport ship, right? Driver: "Yes! Pregnant. Ivan: "Radarman, do you estimate how long it will take for the enemy ship to catch up with Europa." Radarman: "About three hours." Ivan: "Now all engines are shut down, Wenhe, after the shutdown, enter the calculation and detection system, check the condition of all the equipment after this period of operation, and notify me immediately if there is a problem." Wen He: "Yes, I'll start right away." After about two hours of intense busyness, Wen He returned to the command cab: "Sir, all the equipment has been checked, and after one hundred and fifty hours of trial operation, there is no abnormal situation. Finally, Ivan had some light-hearted expression on his face. Thank you for your hard work. Now that our device is completely normal, let's reboot it. All ready, please start the secondary No. 1, secondary No. 2 engine, and secondary No. 3 ready. "Slight vibrations and a slight engine sound re-encircled them. Ivan: "We don't have to play with them anymore." Direction, the nose of the machine is 92 degrees upward, there is no obstacle to obstruct, within 20 minutes, the uniform acceleration to 70,000 per hour, 30 minutes to 110,000, and an hour later to 150,000. Driver: "Yes." Ivan: "I understand that the speed of the enemy ships is up to 70,000, and we can easily get rid of them now." Zhao Li and Duo looked at each other, but did not speak, each stretched out a hand and slapped it in the air. Their ship was fearless, swaggering and speeding along. Zhao Li imagined the scorching and formidable lackey posture of the enemy ship not long ago, but now he watched the prey disappear openly and completely under their noses, and he couldn't help but happily put a smile on his face that had been nervous for a long time. Seeing many facial expressions, Zhaoli estimated that his expressions were also inseparable. ×××××××××××××××××××××××××××××××××××××××××××××××× spacecraft moving in the direction of Saturn's orbit, the long distance, and the long space travel that gave people away, Zhaoli was reluctant to know how long the travel time was, anyway, every day just ate and sleeped, played for a while, dozed too much, and then slept again. Of course, he also exercises occasionally to prevent muscle atrophy and other space diseases from happening to him. They have experienced purposeful travel, but this kind of purposeless travel is the first time. The crampness of the space is accompanied by the endless time, and just sleeping is already a good way, better than sighing from time to time with two eyes open like Chade. His state, the many times he suffered, several people took turns doing his distraction work, what was left on Earth to be no future, no hope, and so on in detail. He also got a bunch of scientists to throw all the mess of knowledge at an artist, whether he understood it or not. Hey, an artist is an artist, he can't be idle, he is either full of pride or completely sunk, it seems that this is not the case with artists in ancient and modern times. The buzzer in the living module sent a message approaching Saturn: "We are only close to Saturn's orbit, and we are still far away from Saturn. Since we are not here to see Saturn, we will only give a brief introduction to Saturn. Saturn is also a gaseous planet with helium and hydrogen as its main components, surrounded by Saturn's rings and more than sixty moons, which are mainly composed of ice or rock. You can see the images of Saturn and several moons that you have taken in the past. After listening to the introduction, Zhaoli, Duofan and Lu Yuan wanted to call Cha De to go to the command cab to learn about the specific situation, but he was not interested at all, and they had no choice but to give up. When they arrived at the command cab, Ivan and Wenhe nodded to them. Ivan humorously: "The wormhole is still there, and it looks like it's still waiting for us to meet it!" He pointed to a pane in front of him, a screen divided into multiple panes: "You see, this is detected by the detector, and the brighter one in the middle is the various rays released by the wormhole when it inhales matter, and we use it to quickly reach another space, which can save a lot of time, it should be said to save more time than you can imagine." We know that even at the speed of light to get to another galaxy closest to the solar system, it would take tens of thousands, hundreds of thousands, hundreds of thousands of years, or even longer. As you know, with the technological level of our human beings, it is currently impossible to travel in the universe at the speed of light, so the most feasible way to solve the distance gap in a short period of time is to use wormholes. Besides, even if we can have the speed technology of light, can you and I live for tens of thousands, tens, hundreds of thousands of years? "You've instilled a lot of knowledge in us, and we all know a rough idea." Personally, I'm more interested in how long it will be before we can get through the wormhole, and if some of us are worried about safety problems. After a pause, he continued: "I am also engaged in physics, but I am not as extensive and proficient as you. You also know that physics is too extensive, what particle physics, mechanical physics, etc., because I have to pass through wormholes, and I have also made up for a while about wormholes over the years. I once saw a more authoritative magazine that said! It's not impossible for humans to cross a wormhole, but there are many prerequisites. I have a few important things in mind, such as one of which mentions that the size of the wormhole must be large, and the diameter of the hole must be more than hundreds of thousands, millions of light years. Because of the large size of this wormhole, the particles in it may be less destructive due to energy dispersion, and only in this way can human beings be under good protection measures, equipment and human equipment will not be torn, so as to achieve successful crossing in a lower particle radiation environment. How do you think the size of the wormhole we are going to pass through is not large, hey! By the way, the article also says that what kind of large volume, wormholes with a diameter of hundreds of thousands or millions of light years or more are difficult to find in the universe! Ivan smiled and said, "You are talking about the opinion of the famous physicist Obright." "That's right! It's his. He nodded his head in acknowledgement. I ask you, no matter what form of particle radiation in the universe, such as a black hole or a star explosion, there is a concentrated part of their energy and a dispersed part, right? That is, there is a very high energy particle radiation form and a lower energy particle radiation form that is far from its radiation center, right? "Hmm! Yes! "Isn't this lower particle emission so that we can use it?" After many moments, it suddenly dawned: "Gross, that's the case, I understand." "We can't use the high energy of radioactive particles, but at a distance from the higher radioactive energy in the center of the wormhole, the radiant energy will be attenuated to a certain extent, and we can't use these attenuated parts?" "You mean to say that our trajectory is to avoid the center of the black hole, which is the entrance of the wormhole, and walk from its edge, from places with low destructive ability, right?" "You're right! Originally, we just wanted to borrow the power of the wormhole to achieve our goal, we can't borrow the big one, and we can't borrow the small one? Now, we don't need to borrow a large volume, but a small wormhole. Although they are large in number and small in size, they are also part of a black hole! Ivan paused: "Even with the help of the edge of the black hole, you need to be cautious, so I have been researching for nearly twenty or thirty years, almost spending all my savings and that of several other scientists, and selling some technology, and borrowing a lot from you and others, and cobbling it together, until now I can put it into practice." Because they have been together for a long time, they no longer use the word "sir" in their address to Ivan, but make people feel closer. Many times: "Ivan, can you explain our equipment and facilities?" "You're interested?" Duofan: "Hmm! Pointing at Zhaoli: "Lao Zhao is particularly interested." Zhao Li glanced at him many times and hurriedly said, "Nonsense! I don't have any interest, I'm engaged in economic work, and I can't fight with these things. Usually it's just out of curiosity to ask you, where did you get any special interest? "Then you keep asking me, actually, I don't know much about these things." Ivan smiled: "It's not a bad thing to be interested. Since I want to know, I'll give you a rough idea! Where to start? Well! Let's start with the core engine. There are two engines on the whole ship that use nuclear fusion materials as fuel sources, one large and one small, the small one is used to provide power for flight, power supply, etc., and the large one is mainly used to provide protective energy for the entire spacecraft when passing through the wormhole. He tilted his head many times and asked: "I heard you say what the second and second engines are, what are they?" "That's to save energy consumption, and from the small engine, a smaller engine is introduced." He nodded many times. Ivan continued: "The detector is very small, so there is nothing to say, and the pilot command system is not much different from other ships, the difference is that its protection is different from other ships. The ship's guards are located on the ship's hull, and they are divided into four layers, the outermost layer is an ultra-high-density material that is resistant to high and low temperatures; The second layer is the particle generator, which is used to create particles to provide particles for the protective layer beyond the surface, and the first and second layers are not completely separated but intersected; This third layer is also a high-density material, which is used to separate the first and second layers; The fourth layer is used to protect our living space, and that's roughly it. Isn't it possible for you to see the thickness from the hatch, the first and second layers account for most of the thickness, and of course the most important, and the first and second layers are the most technical. After many struggles to recall something: "I forgot who said that the ship looked quite large, but it was not very heavy. Who said that? I can't remember it. "It's Gilde, who said it when we loaded the ship." Zhaoli remembers. "Yes! Right! It was he who said it. Ivan nodded: "Well, generally speaking, the weight of a substance is directly proportional to the density of the substance, but it is not necessarily proportional to the volume. There are many things in the world that are large and lightweight, such as Saturn, which we pass by, is very large, but in fact its unit weight is so light that it can float on the water. Obviously, this sentence was especially said to Zhaoli, a layman, and Zhaoli nodded, expressing understanding and thanks.
