A series of orders descended from the joint command ships to the sub-fleet, and finally to the battleship fleet, the space carrier fleet, the cruiser fleet, the heavy landing ship fleet, to every battleship, and even everyone on it.

The space fleet, with a total of 250,000 giant warships, is commanded by a central computer, and the attack and defense are integrated, and every step is extremely precise, and in the silent starry sky, it looks extremely solemn.

The starry sky is traceless, compared with the almost boundless vast starry sky, the space fleet that occupies a huge space is also very narrow in a broad sense, a huge warship breaks away from the overall fleet and flies forward alone, and the Confederate space fleet behind it uses a dark matter trigger to open the wormhole at this time, as if calculated, the battleship disappears into the wormhole in a flash.

This time it was no longer psychological warfare, but a decoy was released. It doesn't matter if the Seth on the other side of the wormhole will be fooled or not, this decoy must be released.

The space twisted, and this battleship, which was not small by any means, transmitted back all the information it received at the moment when the wormhole closed, such as what the other side of the wormhole was like now.

"Give it to the central computer, and immediately analyze the information on it, find out the opponent's troop deployment, and whether there is any hidden power in it." An order issued in an indifferent voice, even if it was a decoy, should try to get the most value out of it, and for a commander, there was no power in the superfluous realm.

The image transmitted back by the decoy was so clear that even the group of commanders in the joint command ship was taken aback, because the visibility around the wormhole was so good.

"Light refractor, is this a battlefield for us? Can't see that there is still a little knightly duel demeanor? A commander of the administrative district of France said in an inexplicable tone, perhaps in admiration or sarcasm.

"Brave knight, it's not that you're dueling, it's war." Another commander next to him reminded.

"The other party's arrangement is simply unobstructed. Is this going to go head-to-head with us? No, the reason why they use the light refractor device is to use a large amount of visible light to organize us to detect the opponent's positional arrangement. "There is always a commander who is focused on the key nodes to speak, and the other side is not hiding its strength, or the other side is not willing to do so.

In the early days of the Space Fleet, the fleet mainly used heat source detection and visible light monitoring to detect enemy ships, which proved to be very easy to be deceived. As long as the interfering heat and light sources are continuously discharged, interference can be easily carried out. So a revolutionary detection method has emerged - gravitational perturbation.

The principle of gravitational perturbation is not complicated, and the gravitational force between celestial bodies affects the trajectory of both sides. This theory led directly to the discovery of Neptune. In the inner solar system, since the gravitational trajectories of major stars have been determined, as long as a reliable model is established, it is possible to detect the deployment of enemy fleets in the monitoring area by detecting gravitational anomalies. And it is impossible for any of the belligerents to release "decoy bombs" weighing hundreds of millions of tons and several kilometers in length.

"Refracting the sun's light source around the wormhole is itself avoiding our use of the light source to detect it." One by one, the news was fed back, and the High Command immediately made targeted arrangements, "Distribute the positions of fixed dwarf planets to all fleets, and at the same time be careful to hide under the light curtain and the areas that are prone to blind spots." After passing through the wormhole, remove the Seth system's light refractor as soon as possible. ”

No detection technique is invulnerable, and gravitational perturbation can detect the opponent's light source spoofing. However, it has little effect on the stars in the gravitational force, and the detection of heat sources also has limitations, so there is no problem with detecting stars, but if the space fleets fight each other, it is easy to use.

In particular, in the image that has just been transmitted back from the Seth Galaxy, the joint command ship has already known that the other party has used a light refractor device, and once the light is refracted, it may also be deceived if it uses light source sensing detection. If in the case of confrontation between the two sides, a salvo of the main guns on the side of the Confederate fleet of mankind hits a mirage, I believe this is a scene that all commanders do not want to see.

"It's almost time, and a fleet of 100 unmanned vehicles will enter the wormhole in the form of bait. The dark matter exciter is prepared, and the central computer calculates the turn-on time. After the unmanned fleet enters the wormhole, all fleets enter the first level of combat readiness. Orders were issued from the joint command ship, "A general assault will be launched in an hour." Fleets inspect weapons, especially the laser-firing cannons of warships. ”

Laser cannons are almost an essential weapon for warships, from battleships, aerospace carriers, to cruisers, destroyers, and almost all of them are equipped, and the reason for equipping this old weapon is because of the cheapness of laser cannons. Rather than how reliable he is, in fact the reliability of laser cannons is very low in some places, light is easily disturbed, and a massive star can make the trajectory of light visibly shifted.

However, once the laser cannons are assembled on a large scale, they can avoid being interfered with to a certain extent. Coupled with the fact that it is cheap, it is still a must-have weapon for today's space fleet.

On the other side of the wormhole, the Seth System Command, which once again found that the wormhole had been opened, was confused about the hundred decoy fleets this time after annihilating the decoy battleship, but immediately began to order an attack.

"What are humans doing here? Test our firepower setup? Why use the refueling tactic? A synthesized sound sounded in the command headquarters, for a civilization that has developed to this extent, it is very unreasonable to add fuel tactics in the space environment, especially when the two sides are evenly matched, there is no technological generation difference, how can it be possible to fight more with less.

The weirdness of it even hindered the operation of many Seth commanders' chips.

"It's right to fight as many as you want, and destroy the opponent's living force." The order was quickly issued, and a salvo of directed energy weapons placed on the major dwarf planets was fired, and the huge pillars of light were extremely conspicuous in this empty station. The scale of a hundred fleets is unintentionally only able to deliver food, even if the flagship of this fleet opens the ion shield, it can only hold on for a few more moments, and it can't change the final result.

At the moment when the ion shield shattered and the battleship was hit, the flagship exploded and turned into brilliant fireworks. But at this moment, a ripple of electromagnetic waves suddenly appeared in the center of the explosion and rapidly expanded, and the high-energy value was almost immediately detected by the Seth System Command, "Giant electromagnetic pulse bomb? Turn on protection now. ”
