<h4>Chapter 129: Maic Track Cannon</h4>


    Maic rail gun, which uses electromaic force to push the shell, is a kic energy weapon with great lethality. This thing is a new concept of science fiction weapon before Huogu travels, and only appears in those science fiction, film and television works and novels.


    Unlike traditional cannons that use violent chemical reactions to provide driving force, the maic track gun itself does not need to consider the powerful shock waves generated by chemical explosions and the smoke after the reaction.


    Whenever traditional artillery is to improve the power of artillery, it is necessary to lengthn the body to stabilize the trajectory, and the amount of shells should berger to provide more powerful shell propulsion.


    In a word, the volume needs to be getting bigger and bigger.


    It doesn''t matter if it''s just like this, but once it is put together with another physicalw, the problem will be very serious.


    The strength of the object will be fragile with the amplification of the shape. The fundamental reason is that the internal stress increases, and the strength provided by the atomic bond can only be barely countered. Once the external force amplifies the stress, it exceeds the force that the atomic bond itself can provide, then the object will disintegrate.


    Therefore, the artillery barrel needs to be thickened, because it is necessary to resist the shock wave caused by the explosion of the shell charge.


    However, maic rail guns do not need to consider this problem, so when Huo Gu was still on the earth, this type of cannon was generally favored by various countries.


    The only problem that countries have not spread this kind of cannon to the army is that energy is too much for the consumption of electric energy. The essence of the maic rail gun is to convert electrical energy into the kic energy that drives the shell.


    On the chaotic battlefield of gunfire, a cannon that is still connected to therge rear nuclear power nt is undoubtedly a bad idea. Mobility alone is enough for the military general to turn around and leave.


    But Huo Gu doesn''t need to think about this.


    Energy supply? Every corner of the earth''s surface, including the seabed, is using chemical energy to generate electricity. There is a whole''s surface power station to supply energy for the maic rail cannon. The low-temperature superconductor realized by dry ice is used to build in the rhizome, and the non-destructive and global coverage of the conductive wire ispleted.


    It was in order to build these that Huo Gu perfunctorilypleted the delivery design of the sky''s eye into space, directly applying the designyout of the earth rocket.


    When the rotated to turn the muzzle direction of the maic track gun to the alien fleet, Huogu''s order was issued.


    "Launch!"


    After the order was given, the fist-sized metal body began to speed up under the action of the electric field.


    Due to the need to fight against the gravity of the itself, the speed of the metal body can only increase by ten meters per second for each meter. The air resistance is negligible. In order to avoid friction and heat generation, the whole giant structure spontaneousbustion urs. Huo Gu pulls all the internal air away and is in a vacuum state. The muzzle has prated into the air. In the looseyer, there is no need to worry too much about the entry of air from the top to bottom.


    The length of the orbital cannon has reached 1,000km, which is a monster-like material science that even human beings on earth have never mastered.


    This is Huo Gu''s umtion for such a long time since he traveled, and it is also the reason why Huo Gu didn''t call them to study chemistry forever.


    The essence of chemistry is the atomic bond structure of the interconnection between atoms. The whole macro world is built by losing electrons and obtaining electrons. More fundamentally, it is the ''electromaic force'' of one of the four forces on the microscopic scale.


    With this cognition, Huo Gu has been constantly trying various types of atomicbinations since the Hadesan period. As long as the atoms can be obtained on the, they have basically beenbined.


    Huo Gu''s understanding of chemistry is as difficult as a child''s understanding of assembled building blocks, let alone such a long umtion.


    ording to the conversion, the length of the maic rail gun barrel is about equal to the speed of the shell itself, that is to say, the initial speed of the fist-sized shell leaving the muzzle is 10,000km/s.


    What kind of concept is this?


    This is one-third of the speed of light.


    The elerated projectile itself has a mass of 10kg, and its kic energy has reached 50 million joules. Basically, there is no atomic bond that can resist this level of kic energy.The key is that there is more than one projectileunched into the universe. Due to the particrity of the maic track gun itself, there is no need to consider the tightness of the explosive cabin at all. The way of dropping the shell is very simr to the famous ''metal storm'' that once hit the earth. It doesn''t matter if the interval between the cannonballs advancing in orbit is reduced to one meter. Because of the vacuum environment in the barrel, there is no need to consider the acupoint effect.


    There is not only one simr building, so the scene is a horrible barrage with a speed of 30th of light, and 500 billion fist-sized bullets are projected.


    However, although these bullets are very powerful, it still takes seven or eight hours to hit the target, which gives the alien fleet time to react.


    The urgent report of the announcer echoed in the bridge.


    "Commander! Radar echo scans arge number of objects approaching at high speed! Speed 10000km/s! Launch direction, target star!"


    "Tell the whole ship to change the course, scatter the formation, and open the spacing.


    The fleetmander gave the order calmly, and his eyes locked the projector, on which showed a circle of blood-red warning signs approaching his fleet at high speed.


    The time is the fifth hour behind the scenes of Huo Gu''sunch of those metal bombs. Because the two sides are close at high speed, the rtive speed is higher and the meeting time is shorter.


    Even on the bridge, aliens can obviously feel a kind of micro-shock. Obviously, the spacecraft was hit.


    "Thirty ces of vibration armor are damaged!"


    "Good airtightness!"


    "The engine group is normal!"


    "The life-sisting system is normal!"


    "Four forts were damaged!"


    ...


    The sound of the report came one after another, and themander''s tense look showed a little rxation, and then asked.


    "What''s the situation of each ship?"


    "Six ships have been confirmed to be damaged due to too many bullets. The three ships are being repaired due to hitting the vector nozzle, which may affect the deceleration of the spacecraft behind. Other ships survived because of your previous order to turn on the vibration armor, but the extra vibration armor was damaged."


    Themander nodded slightly and ordered again.


    "Teach the maintenance team to repair the vibration armor as soon as possible. This kind of attack can never be only once, and the ships should keep their current scattered formation unchanged."


    "Yes!"


    If Huo Gu knew the result of the attack, he would be so angry that if it had feet.


    Although it can''t be said that there are high hopes for this wave of attacks and it is believed that it can win or lose at one time, the result of this battle is far lower than Huo Gu''s original expected result.


    The existence of vibrational armor made Huo Gu''s raid die, which consumed a lot of energy, material and energy in exchange for only six of the ten thousand warships.
