The 2,000 UFOs plus four spacecraft are sparsely distributed in the space range of tens of millions of miles... Such a wide distribution is to prevent being taken away by powerful enemies. At least, even if the technological gap is too large, it can ensure that the human army has enough time to engage in entangled combat. Guerrilla warfare has always been one of the best combat theories - of course, just theory, how to apply it depends on the commander and actual situation. Of course, excellent guerrilla warfare cannot be separated from powerful communication technology; fortunately, human confidence and ultra-long-distance communication technology are relatively ideal. Long before departure, Mo Wentian had already prepared for guerrilla warfare.

Tang Qichang is just an ordinary fighter soldier, flying a 50-meter-long, tetrahedral-shaped fighter. The interior of such a fighter is relatively small, but it has the advantage that six edges can place rail guns up to 45 meters long to achieve the arrangement of space weapons without dead corners! And four planes can effectively arrange energy protection layers. In addition, the tetrahedral in space can form a "tilted deck" defense in the concept of war weapons. It can not only effectively slow down physical impacts, but also increase the thickness of the shell in disguise by tilting, but the nearly absolutely smooth surface can effectively "reflect" type of defense against light weapons! For weapons such as lasers, mirror reflection is a good defense method.

At this moment, when the war had begun, Tang Qichang was quietly lying in the fighter, with his thinking connected to the central computer. He absorbed the essence of a variety of civilizations. Today's computers are not only electronic technology, magnetic field technology, etc., and even have the perfect fusion of optical brain technology and formations. Such computers can effectively resist electromagnetic interference! In theory, even if they are in the powerful magnetic field of neutron stars, the optical brain technology in them can still operate normally, ensuring that the computer has at least 30% of its functions.

In addition, this small fighter aircraft is equipped with four types of weapons; as the saying goes, sparrows are small and all-in-one. The first two are of course lasers and rail cannons, the third is optical magnet weapons, and the fourth is "neutron knife"! The reason why it is called neutron knife is that under the impact of ions at high speed, any known substance is like rotten wood. Under the impact of neutrons with a speed of up to 0.95 times the speed of light, even the hardest picometer-level material.

The beach under the same flowing water will be stripped off layer by layer. If you are a metaphor, a neutron knife is like a rail cannon in the microscopic world! A high-speed neutron flow can lift the atoms in the material layer by layer! It is reflected in the appearance: after a light green and hazy light column hits an object, a wave like water marks will appear on the surface; and in such fluctuations, the surface of the material quickly disappears out of thin air! It can penetrate a standard steel plate of ten meters thick in a few milliseconds!

"Accelerate forward!" Mo Wentian's command has always been known for his boldness. At that time, he attacked the Greeze world across more than 350 billion kilometers, creating a new era of human ultra-long-distance attack; and with the development of human technology, the attack distance of weapons and space exploration and positioning technology have developed rapidly, and now it has developed to the goal of attacking low-speed and regular movements a few light years away; and for high-speed moving objects such as spacecraft, they have a relatively accurate ability to cover attacks of one light year.

The guide rail cannon projectiles that whizzed past the spacecraft formation before is a way to cover the attack. The current speed of the spacecraft is 0.7 times the speed of light, while the speed of the guide rail cannon is above 0.8 times the speed of light; although there are not many 450 shells, they are enough to form a "semi-precision" coverage attack within a certain range under precise calculations! The so-called semi-precision is relative to precision. In the universe, the environment is too complex, and even if humans have undergone the most stringent precise calculations, they still make mistakes. In the words of practice, it is "the powers cannot defeat the number of days"!

"Preparation!" After only less than half a day, a new order was issued! All spacecraft, fighter plane, flying saucer, etc. fired again! If the last attack was to make up for the gap for 450 shells, then now it will completely cover the attack! "Rail cannon attack, the first wave of attack, all shells have a hardness of 100 grams, and the initial speed is 0.1 times the speed of light!"

The initial speed of 0.1 times the speed of light, plus the current speed of the spacecraft formation, is 0.8 times the speed of light! Of course, due to the problem of time and space, the actual speed of these shells can only be infinitely close to 0.8 times the speed of light! The so-called standard hardness is pure iron hardness. A powerful rail cannon requires too much data to calculate. Different projectile hardness will have completely different effects.

Considering that 99% of the enemy spacecraft may have energy protection technology, after strict calculations and rigorous combat thinking, the first to fire standard soft iron projectiles. Soft iron, under the acceleration of powerful rail cannons, the huge acceleration will compress the projectiles into flat shape, and the soft iron projectiles will be deformed at the moment of exit! Such shells cannot fly in the atmosphere, and the huge resistance will instantly turn the shells into flames and dissipate. However, in space without resistance, such shells can have a large enough contact area! They can release huge kinetic energy at the first time they come into contact with the target, greatly destroying the defense layer on the surface of the target. It is the most ideal weapon to consume energy protection layer. Although the blade edge is sharp, the overall strength is smaller than that of the hammer!

"Flash!" Wrapped in the silicone layer, Tang Qichang could operate this fighter with a side length of fifty meters just by thinking. In an instant, one side of the fighter pointed straight towards the distant deep space, where there were only a few dim stars, and there seemed to be nothing. However, Tang Qichang didn't care at all. He strictly followed the plan and aimed the shell at the calculated coordinates and fired it decisively.

The huge kinetic energy acted on the fighter in an instant. In an instant, Tang Qichang felt that his "body" was subjected to a huge reaction force. The force that occurred in this moment was only 0.01 seconds. However, the reaction force generated in this 0.01 second even exceeded the engine's thrust, which instantly reduced the speed of the fighter by 100 meters in seconds!

"Accelerate! Accelerate to the original speed!" Mo Wentian's voice was calm, as calm as a glacier.

"Dou..." Signals indicate that the corresponding spacecraft, fighter plane, and flying saucer accelerate to their original state.

"Preparation!" Mo Wentian's voice was like the god of death who dominated life and death. "1 gram super hard shell, maximum power launch!"

"Gala..." Tang Qichang instantly controlled the machine to roll out a "cannonball" that was only the size of a needle tip. This cannonball made with Pimi technology is sufficient at extremely high speeds to any existing and theoretical energy protection technology known to humans. When the weapon is extremely small, it can cut into the "waves" of energy protection technology, so that the energy protection technology will almost fail in a certain state!

Under the existing theory of energy protection technology of humans, all actions require the interference of "waves". Such energy protection technology has excellent protection capabilities for weapons such as light, magnetism, and fields, and also has excellent protection capabilities for large objects; however, such protection technology is powerless for ultra-small and ultra-high-speed objects. Just like a fishing net that can catch fish, but it is difficult to catch small shrimps!

"Preparation! Aim at your own coordinates and fire three free times!" The rail cannon fired five times in the first and second time, directly consuming one unit of electricity. The rail cannon has great destructive power. However, this is based on high energy consumption.

"Bang! Bang! Bang!" Tang Qichang fired three times in a row in just one hour. The powerful bright blue electric sparks lingered around the guide rail muzzle, like the pattern of hell...

Now the distance between the two sides is already less than one light-year, but even so. Such distance makes the existing light energy weapons or field-state weapons of human beings weak enough to have no substantial damage.

However, physical weapons are the other extreme! Because both sides are accelerating and approaching, the absolute speed of the shell is as high as 0.8 times the speed of light; if the speed of the two are approaching, it is equivalent to the relative speed of the shell is as high as 0.9 times the speed of light! The kinetic energy of the physical shell is theoretically not lost!

The speed of a physical projectile is as high as 0.9 times the speed of light, which cannot be described as horror.

———————

When the attack began by humans on Earth, humans from the Holy Sun Empire had also detected traces of humans with advanced technology.

Lieyang, Guang, Shenghui is already in his seventies and his body has begun to enter the middle-aged and late-year stage; however, his ambition has not decreased at all; on the contrary, because the first life planet and the traces of intelligent life have been detected, it exploded! Especially the planet in front (Zhurong Star) looks less defensive power than the most barren galaxy in the Holy Yang Empire! In Lieyang, Guang, Shenghui's eyes, it is a huge treasure with almost no defense!

"Your Highness, I detected that the other party took the initiative to attack. Now it is 0.92 light years away. Also, the other party actually knows to use the theory of time and space to stop us from moving forward." Yongguang Rong Hongyun stood quietly behind Lieyang Guang Shenghui to report. As a direct descendant of the man Yongguang Rong Yong, Hong Yun has been loyal to the prince since he was a child.

"Well? They took the initiative to attack?" Lieyang, Guang, Shenghui was a little surprised. In order to advance safely, the fleet of the Holy Yang Empire did not rush around with his eyes closed. There were also tiny detectors that attacked the forwards in front. These detectors were not discovered by humans because of their alternative technology, superb hidden means, and small size. These tiny, but very fast detectors have already captured traces of humans on Earth and returned the signal to the fleet of the Holy Yang Empire.

What surprised Lieyang Ming Shenghui was that this seemingly weak civilization not only dared to take the initiative, but also could lock itself in space. It also used space-time phenomena to snipe and intercept them, which surprised Shenghui a little! "Well, but that's it, after all, 'they' have entered the era of cosmic immigration, and discovering space-time phenomena should not be a problem.

By the way, since they took the initiative to attack, let's keep these spacecraft! Only four small and medium-sized spacecraft want to stop the great and powerful Holy Sun Empire. They are dreaming!"

"Yes! Arrange a counterattack now!"

The technology of the Holy Sun Empire is not without weaknesses. In order to meet the goal of hitting a light year away, low-power energy cannons have to be used! The high-power energy cannons have a short range and will quickly decompose after entering space; therefore, the effective range is less than one million kilometers. However, in the eyes of Lieyang, Light, Shenghui and all the people of the Holy Sun Emperor, the low-power energy cannons here are enough to destroy those "natives"!

Just half an hour later, 96 ships belonging to the Holy Sun Empire neatly emitted light blue beams in an instant. Although they were low-power energy cannons, the so-called low power refers to the standards of the Holy Sun Empire, not the standards of humans on Earth. After all, no matter what, the history of the sky civilization development in the Pearl Star Domain has exceeded ten thousand years. Even if it advances a little bit every year, it will be enough to cause huge changes in technology over ten thousand years.

Unlike human laser weapons or optical magnet weapons, the speed of light weapons of the Holy Yang Empire have already had a nearly liquid luster. From the outside, each of the emitted light columns is 10,000 kilometers long (one-thirty-eighth part of a second launch time), and the thickness of the energy cannon (column) is different. The smallest is only the thickness of the finger, and the largest one is launched by a spacecraft with a diameter of only one meter!

Because the energy is too concentrated, it not only shows a substantial luster like a water flow, but even fluctuations like water light - this is a manifestation of extreme energy compression and concentration! Such technology is actually just the enemy aircraft energy cannon of the Lieyang Empire, and the most powerful laser technology of human beings has not reached this standard! It is also because the energy reaches a certain degree of saturation and scattering that these energy cannon light columns are displayed in the dark universe and can be seen with the naked eye.

They have a faint light blue light and water-like fluctuations; they look magnificent! However, these are all fatal and dangerous energy cannons!

Each energy cannon is a "light column" with a length of ten thousand kilometers. The light columns of tens of thousands of kilometers are moving forward at the speed of light in the universe, leaving blue marks in the starry sky!

Like, lightning that pierces the sky!!!

This is a strange space battle. Before the two sides contacted each other, to be precise, it was impossible to see it at all, the war had begun! This is the battle in the starry sky!

From this point of view, we can see that as an interstellar civilization, the minimum requirement is to master a certain secret of time and space; otherwise it is not a problem of backwardness, but it does not have the basis for interstellar war or even star survival! (To be continued...)

ps: By the way, it is really difficult to describe a scene that is different from traditional combat. Some data, even the approximate data, must be constantly checked; some concepts also need to be considered. I need to modify at least one thousand words for a picture of more than 3,000 words!
