"Fuel tank splicing... Left precision adjustment of ten nanometers..."


    "The seventh group can go to the welding robot! Enter from the e78 channel!"


    "Empty the weapon Bay first! Tell them not to enter any weapons. They can install weapons only after the reaction device is tested! Understand?"


    With the combination of manual scheduling and computer, the Star Destroyer Longzhu gradually took shape in the dock.


    Du Xingyu was not at the scene. He was testing a new space weapon - Electromagnetic Pulse gun on the lunar base at this time!


    Electromagnetic pulse is a kind of microwave weapon, which uses directional radiation generated by energy to kill and destroy targets with high-power microwave beams.


    After seeing motley, an alien "terminator" robot, humans have done in-depth research on how to attack robots and warships.


    In the study of motley, they found that electromagnetic weapons are a more efficient means of attack than laser weapons.


    Although laser weapons have strong penetration, they can attack large targets and can not destroy targets instantly.


    At this time, high-power electromagnetic pulse can be used. With electromagnetic pulse gun, you can instantly "paralyze" a robot, UAV or a part of a warship in an area!


    There is no doubt that it will be a necessary part of mankind''s new generation of space warships.


    "EMP gun, the first attack." at the lunar military test site, the EMP gun was aimed at the high-speed unmanned space fighter.


    "Attack!" at Du Xingyu''s command, the EMP gun generates a fixed high-power microwave beam under the guidance of the radar system.


    The beam formed by microwave travels at the speed of light. From the perspective of human observation, it has attacked the unmanned space fighter almost instantaneously.


    "Zizizi..." the electronic equipment in the unmanned space fighter made a noise. Then, all its electronic systems failed and became a scrapped fighter.


    "The effect is not bad. I''ll try a regional space electromagnetic shell next time." Du Xingyu was satisfied with the test effect.


    In the test site, a large number of satellites were sent out.


    The electromagnetic bomb was launched and exploded at a fixed point, producing an instantaneous strong electromagnetic field, and all satellites in an area were shut down and scrapped in an instant.


    "Electromagnetic damage assessment is 75.4 percent." in each test, they will obtain various data, such as strike distance, instantaneous strength of electromagnetic field, electromagnetic penetration, etc.


    "If the EMP gun is installed on the Star Destroyer and launched with its energy, it can immediately shut down the space cruise ship like Yinyi!" Du Xingyu exclaimed, "if we can have such an attack means, the enemy will certainly have it."


    "All our warships must update the anti electromagnetic function."


    ……


    Half a month later, Du Xingyu received a report from Longgang dock. The Star Destroyer Longzhu was finally assembled and was about to start the first "reaction force" test.


    After testing, they will install weapons, fly into the spaceport and officially serve.


    Du Xingyu can''t be absent for such an important thing.


    In the largest dock room in Longgang, Longzhu lay there quietly. Its appearance alone shocked countless people.


    It is a three-dimensional shape of an inverted pyramid with tips at the top and bottom. Each corner is equipped with signal receiver, laser emission, electromagnetic pulse and other devices.


    The pyramid of Khufu is 146.59 meters high, which is already a wonder of human civilization. The maximum height of this inverted pyramid Star Destroyer is 4788.34 meters, which is 4.6 times the maximum length of the keel!


    The last time humans built such a tall thing was the tower of a space elevator.


    Standing under the dragon column, everyone can only look up to this behemoth and be impressed by its grandeur!


    The strong sense of oppression brought by various high-tech weapons is suffocating!


    The surface of the Star Destroyer Longzhu has anti radiation, anti electromagnetic and "space stealth" functions. It can minimize the influence of light refraction. If it is in space, it is difficult for ordinary reconnaissance satellites to find it.


    The internal components are more complex than words. In short, this is the crystallization of human wisdom. So far, the most powerful planetary space warship can be made in the human space age!


    "Amazing!" Liu Yuan, an aerospace dynamics expert and academician of the Chinese Academy of engineering, was amazed.


    "It''s worth seeing the dragon ball before death!" Liu Yuan commented.


    "Teacher, you can certainly live a long life!" said Dong Jiangbo, his student behind him and the world-renowned founder of Xingyao space technology.


    Today, Dong Jiangbo is no longer as rich as he was in those days. After more than ten years of hard work, he has become thin and old. He looks a lot older than his actual age.


    "Teacher, you can board the ship later," said Du Xingyu.


    "Of course I want to board the ship!" Liu Yuan affirmed. "If I don''t board the ship, I won''t come in vain?"


    "Ha ha!" Xiong Ming and other old experts from the space agency laughed and said, "don''t mention boarding the ship. We all want to live on the dragon ball!"


    "Well, I''ll ask them to reserve a place for your predecessors," said Wang Yu. "We can also be members of the Longzhu!"


    They joked that the dragon ball was ready for testing.


    The most worrying thing about the whole Longzhu is the reaction device, which determines whether the Longzhu can be successfully put into service.


    "Get ready to start!" Du Xingyu has come to the ground command room.


    "Longzhu received!" thousands of crew have been stationed in the Longzhu. This number will increase to 100000 in the future!


    The captain of Longzhu is Zhu Zhenxing, the former captain of Longjiao. The Dragon horn has a new captain.


    "Start the warship!" Zhu Zhenxing ordered that the warship''s intelligent systems and operators begin to work, and each system is activated.


    From the appearance, the whole dragon ball seems to flash through a blue power grid. This behemoth wakes up!


    "Start the reaction device!" Zhu Zhenxing gave the second instruction. The reaction device was activated, and the energy in the nuclear fusion reactor was continuously input into the device, forming a force opposite to the earth''s gravity.


    "Report to the commander-in-chief that the reaction device has been started. Longzhu applies to remove the steel support!" Zhu Zhenhui reported.


    "Approval. Longgang, remove the support!" said Du Xingyu.


    "Longgang received it." Hu Chun, the person in charge of Longgang, immediately conveyed the instruction, "everyone listen to the order and remove the steel support!"


    The dragon ball is now supported by a huge steel skeleton. With this command, the steel skeleton began to shrink down and gradually separated from the dragon ball.


    If the reaction device does not work, the Longzhu will sink with the steel skeleton. If the reaction device works, the dragon ball will be "suspended" in the air!


    At this moment, everyone stared at the dragon ball and the monitoring screen for fear of an accident.


    Rao has seen thousands of simulation scenes on the science and technology simulator, and Du Xingyu''s heart is still nervous.


    For more than two years, mankind has no time to start again! According to his previous calculation, the fleet of alien civilization will be near the earth in more than half a year!


    In such a short time, they can''t build a second Star Destroyer!


    "One millimeter!" the sensor of Longzhu can detect the distance between the base and the steel frame.


    The steel frame has sunk a millimeter, and the dragon ball has not sunk with it!


    On the dragon ball, Zhu Zhenxing clenched his fist.


    "One centimeter!" the steel skeleton is still sinking. People can know the current distance through the computer, but there is no difference from the scene.


    "One meter!" the steel skeleton has been separated from the dragon ball, and the huge inverted pyramid space Star Destroyer is still suspended in the air!


    No sinking, no shaking! It''s like it''s fixed there!


    "The steel frame sinks thirty meters!"


    "The steel skeleton has sunk 100 meters... The support skeleton has shrunk." Hu Chun''s tone of report was full of uncontrollable joy.


    "My God!" at the scene, a North American scientist who came to watch watched the miracle with his mouth open and his head up!


    "It''s a miracle! Without a jet, it''s suspended in the air. It''s a Star Destroyer weighing millions of tons!" a female scholar from Europe kissed the earth excitedly to express her mood.


    "Perfect, too perfect!" a physicist sincerely praised, "gravity and reaction have reached a perfect balance at this moment! We want to record that this is the greatest moment of this century!"


    "Is this the hope of mankind that super warships can attack all targets on the planet in space?" muttered the experts of the island country.


    ……


    "No regrets in this life!" Liu Yuan said with a deep breath.


    "The reaction device seems to have no problem at first," Du Xingyu said. "Now let it take off and move it to see how to maintain its balance ability in flight."


    "Yes!" Zhu Zhenxing ordered to turn on the kinetic energy device of the warship and began to let the warship take off slowly and fly on the sea of the test site.


    Such a huge inverted pyramid warship, the whole flight process is very stable. In the command cabin of the warship, they also specially set up a group of dominoes on the table to test the capabilities of the reaction system and inertial stability system.


    Until the end of the flight test process, the dominoes on the table were stable as before, and no card fell!


    "The first test of anti gravity device and inertial stabilization device was successful." Du Xingyu can announce the results, "Longzhu can install weapons and be ready for service!"


    Since the space age, in order to deal with the crisis, all space weapons have been directly used after preliminary tests. This was unimaginable before. In previous times, even a group of accessories had to be tested for several years.


    However, it is found that the failure rate of these new technology products is very low, and there is basically no design failure. The reason is naturally that Du Xingyu has already simulated countless times with the technology simulator and has already repaired the defects.


    It was another week of space weapons assembly and re testing. The Longzhu was finally fully assembled and launched into the near earth space port for official service!
