At the moment when the vanguard of the black wind fleet jumped to Tianyuan, Tianyuan''s counterattack had already started. The main counterattack force was Tianyuan''s Orbital Defense Forces.


    The armed forces of Xingyao Federation are divided into four levels. At the top level, naturally, is a deep space fleet that can easily perform dozens of leaps across the world, has a deterrent range of more than 100 light years, and can cruise and fight independently for several years.


    The deep space fleet is similar to the "black wind fleet" of the imperial expeditionary force, far superior to the original meaning of the word "fleet". It has perfect self circulation and survival and development ability. In a sense, it can exist independently as a miniature star ship civilization.


    From Xinghai Empire, Xinghai Republic, to human Empire and Xingyao Federation, every deep space fleet has an unwritten rule that the proportion of female soldiers in the fleet should not be less than 30%. In this way, once the deep space fleet cruises in the depths of Xinghai, the home country will suffer a devastating blow. Relying on this fleet alone, the civilization of the home country can be inherited!


    It can be imagined that such a fleet, with its strength and configuration, often gathers the most elite fighters, the most intelligent commanders, the most advanced star ships, the most powerful crystal armor, and even the unique giant soldiers. It is not only the most precious mobile power of a civilization in the battle of the stars, but also the location of all the elites!


    In the Xingyao Federation, there are two "deep space fleet" which are qualified to be called, the "Liaoyuan fleet" as the main trump force and the "big white fleet" as the fast strike force and good at surprise attack and breakthrough.


    One level lower than the deep space fleet is the Defense Fleet stationed in the major world, such as the "Tianyuan fleet" defending the capital.


    Although the name sounds majestic, the starships of these defense fleets are often small in size, with weak psionic shields, armor and firepower. The most important thing is that their structure is relatively simple and fragile, and they can''t stand the repeated tearing and restructuring brought about by many leaps across the star sea, so it''s difficult to strike across the world.


    Their combat radius is often only the world they defend. If it is a single galaxy world like Tianyuan, it will not exceed the scope of a galaxy, or even shrink in the inner resource rich area close to the star. Even the barren and barren places on the edge of the galaxy will not be easily involved.


    Although the Tianyuan fleet is a garrison of the capital, the Xingyao Federation has expanded too fast in the past 100 years. The seven worlds, plus the Baihua and dragon and snake star regions, have to be fortified everywhere, and no matter how large the forces are, they are all stretched.


    What''s more, tianyuanjie is the most typical single star system world. More than 90% of the resources are concentrated on tianyuanxing and the two planets before and after. It is not necessary and impossible to maintain a powerful trump force such as Liaoyuan fleet just for defense.


    Therefore, compared with the flying star world and the Tianhuan world, which have a long tradition of starship refining, and even half a world of starship civilization, the strength of the Tianyuan fleet can only be said to be mediocre.


    It is the third defense force of the Federation, the low earth orbit force, that really defends tianyuanxing and makes all the members of the Federal Parliament and the tens of billions of people living in tianyuanxing feel at ease.


    The low earth orbit force of tianyuanjie consists of nine asteroid fortresses deployed in the synchronous orbit of tianyuanxing.


    These asteroids are in the long century, one after another from the outer space of tianyuanjie after the installation of giant dynamic array, slowly moved here, by tianyuanxing''s gravitational circle capture, become super micro "satellite".


    They are all resource planets. Originally, the purpose of moving to the synchronous orbit of Tianyuan star was to collect various kinds of spars and veins rich in its interior, so as to provide material basis for the explosive development of Tianyuan star in the "Golden Century".


    However, after all the spars and veins have been collected, and these asteroids have become riddled with empty shells, the high-level officials of the military, Parliament and the association of refiners think almost at the same time - rather than trying to figure out how to drag them away or destroy them, they should transform them into fortresses of war and serve as an impregnable barrier for the capital!


    The reconstruction project of the first asteroid, which lasted for 30 years, has not been completed completely. However, it has turned these nine asteroids into formidable steel hedgehogs.


    The mines of the past have become underground arsenals. Powerful super heavy crystal magnetic cannons, particle cannons and dark light cannons are dormant in the depths of the asteroids. Numerous space shuttle bases and armored division bases are set up on them. Most of the soldiers of the garrison are deployed in the asteroid bases, and they can get rid of the trivial gravity to kill the sea of stars at any time.


    In addition, among the asteroids, the cosmic minefield composed of countless abandoned starships and cosmic mines has become the leading death line in the seven worlds of the Federation!


    This so-called "Tianyuan iron wall" low earth orbit defense line is Tianyuan''s biggest reliance.


    In the minds of many people in the capital, with such a solid and indestructible defense line, even the fourth and last defense force, the ground defense force, seems to have become insignificant.


    The vanguard of the black wind fleet was guided by the "Stargate" and came directly to the resource rich area inside the Tianyuan galaxy. The offensive and defensive sides were close to each other almost instantly, so they were attacked fiercely by the "Tianyuan iron wall" before they broke free from the vertigo of space shock.


    From nine asteroid fortresses and countless semi fixed armory fortresses transformed from abandoned starships, streams of Colorful streamers are like substance, tens of thousands of light beams instantly devour hundreds of thousands of kilometers, such as a storm, smashing on the head of the black wind fleet.


    The first wave of attack lasted 60 seconds, but the effect was not satisfactory. Both the ultra-high frequency dark light with extremely short wavelength and the high-energy particle beam were engulfed by the fog surrounding the black wind fleet.


    This layer of war fog is like a magic power with disturbing and dispersing powers. After entering it, the straight dark light loses its direction like a headless fly, refracts and disperses randomly. At last, it passes through the battle array of the black wind fleet without hitting any target and shoots towards the deep sea of stars, or it turns into colorful light patterns, For the war fog rendering a layer of color in full swing, even like the black wind fleet put on a majestic robe!


    Until now, the superalloy projectiles driven by the force of crystal magnetic agitation came late to strike the black wind fleet at the physical level.


    But the fog of war is also accompanied by a strong interference effect of force field. Most of the crystal magnetic projectiles are gently "pushed" out by the arc magnetic field, and "slid" away from the surface of the black wind warship!


    "The enemy''s stealth technology, force field jamming technology and psionic shield technology are all above our army. 99% of the attacks just now have failed!"


    "However, at the moment of attack, the shape scanning of the enemy''s warships was initially completed, and more than 20 main warships of the enemy could be identified, including the largest flagship, the black vortex. In the sky, the black wind fleet was crazy. After the first jump, it jumped over its flagship and was ready for a decisive strategic battle with us?"


    "The enemy ships are changing their formation from jumping to fighting. Their target is area 22.45.28, which is the location of our star gate No.1!"


    "The general staff has studied and judged that the tactical goal of the black wind fleet is to capture the gate of the No.1 star sky and create favorable conditions for the coming of the following main fleet!"


    The cold voice echoed over the Defense Council command center. Looking at the black wind fleet scattered on the light curtain, they became clearer and more active now!


    The appearance of "black whirlpool", the flagship of the black wind fleet, made everyone realize that this is not a bluff feint, nor a trick to divert the tiger from the mountain, but a decisive strategic battle!


    "Ladies and gentlemen, this is a great opportunity for our army."


    Speaker Wan GuQing lowered his eyelids and looked at the sweaty generals and strong men. Even at the moment, his voice did not have any impassioned momentum, but the slow and steady taste was unexpected and reassuring.


    "As we all know, the black wind fleet is by no means the only enemy we face. It is entirely possible for the human Empire to send a second expeditionary force in a few years or more.


    "It''s meaningless for the survival of the union to win the long-term war by hovering with the black wind fleet for several years.


    "Only in a strategic decisive battle in which both sides have done their best, can we defeat the main force of the enemy at one stroke, end the war cleanly, show the strength of the Federation, and win more than ten or twenty years of precious breathing time, which is our only hope!


    "Therefore, in the past few years, we have been painstakingly studying how to drag the black wind fleet into a decisive battle, but we have never found a chance.


    "Now the black wind fleet has even sent its flagship to the door, and the decisive battle has broken out. This is God''s blessing. Why are you so worried?


    "The current situation is very obvious. The black wind fleet wants to completely occupy and destroy the three star gates around Tianyuan star, prevent our main Liaoyuan fleet from returning to defense, and completely occupy Tianyuan star before Liaoyuan fleet arrives!


    "For our army, as long as we can guard the gate of the starry sky, prevent the follow-up forces of the black wind fleet from appearing, let the Liaoyuan fleet jump back in time, gather the strength of the Liaoyuan fleet, the Great White Fleet, the Tianyuan fleet and the low earth orbit defense forces, and destroy many enemy main ships including the black vortex at one stroke, Then the black wind fleet completely lost the ability to launch the second attack!


    "The Tianyuan fleet, the Great White Fleet, and the low earth orbit defense forces will, at all costs, drag down the black wind fleet until the Liaoyuan fleet appears! This is the first battle that will determine the survival of the Federation. It is also the most important star battle on the way to the rise of the Federation. The efforts of countless martyrs and compatriots in the past hundred years, do your best in this battle, everyone
