The glowing nebula, like a burning cloud, is silent in the universe, and the world is actually colorless. The colors that humans perceive are just different reactions to light in the mind through the optic nerve.

In this vast starry sky, that red cloud, since ancient times, has existed in this star field in its original form. It was only when the first human spaceship passed by here and saw her that she was given this magnificent appearance, a name as brilliant as the clouds in the sky.

From the era of human space exploration to the present, she silently watched one after another human spacecraft emerge from here and disappear from here. Gradually, the number of ships coming and going became more and more. The whole waterway is full of traffic and bustling.

Ten years, fifty years, one hundred years, one thousand years...""Generations of space travelers, explorers, and merchants have passed through this passageway, and as time passes, they never come again. New people have joined them to continue the journey of human civilization. And now, the most on this waterway are not scientific research ships, merchant ships and exploration ships, but warships.

On the side of the asteroid belt and cosmic dust 1.2 million kilometers from the fortress, a reconnaissance satellite floats silently among the rubble and dust.

This is a black military satellite. Looks like a bee with square wings.

Above its head, a ring of radar is constantly running, and the telescope lens on its circular body rotates every two minutes, closely monitoring everything around it. No wind or grass, even subtle changes in cosmic waves, can escape its keen perception.

There are many satellites like this in this airspace that has been operated by the Republic of Fiyan for a hundred years. They have different shapes, different working principles, and different properties. Just lurk quietly in the asteroid belt and cosmic dust, and take everything under your control.

A jealous reconnaissance ship slowly broke open. Solidified cosmic dust appeared next to the black military satellite.

This is a small reconnaissance ship of the Feiyan [Vigilance]-class that is nearly four-fifths smaller than even smaller than small frigates. Space jumps cannot be performed, and ultra-long-range reconnaissance missions cannot be performed using jump lanes. Therefore, the usual role of such a ship with a three-person reconnaissance team is to serve as the eyes of the fleet.

At this moment, in the [alert] wheelhouse, three Feiyang naval scouts were nervously monitoring the various reconnaissance instruments in the engine room. "Pete..."-Look at this." A young soldier with sparse yellow hair and pale blue eyes gently touched his skinny companion beside him: "The cosmic wave has changed. ”

"It's supposed to be a meteor swarm." -" The skinny companion poked his head out, carefully looked at the instrument screen and data, and said affirmatively: "The data change has not exceeded the warning line, just leave it alone, understand!" "Understood."

"Hey, you say, where will the bandit fleet be now?" The main control navigator in the front row of the cabin, Xiao -, r, avoids a large rock tumbling in front of him, breathes a sigh of relief, and turns his head to ask.

"I don't think they're going to come in the middle of us." The skinny observer Pete was tapping the virtual keyboard quickly with both hands, while half-squinting, carefully checking the data on the screen, and said: "The greatest possibility of the bandit fleet is to attack the third mixed fleet on our right flank, after all, the terrain is more open." ”

He struck the last key, leaned back in his chair, and continued, "It's not the first time we've had a drill here. Last time, the 23rd Army and the 25th Army fleet were the Blue Army, and a full twelve A-class fleets attacked here, what was the end? ”

Observer Pete's words caused the two companions to nod violently.

They still remember that exercise vividly. At that time, the 32nd Army only sent two A-class fleets to cooperate with the fleet of democratic forces to defend this airspace. As a result, no matter what tricks the other party plays, it will be useless. Twelve A-class fleets smashed into pieces on this defensive line. The left flank of the defense line is easy to defend and difficult to attack, and it is very easy to be forced into the gravitational capture zone of the white dwarf by the defending fleet.

Although the attacking battleship is forced into the gravitational capture zone, it is not that it will not be able to break out, or it will be swallowed. However, the capture zone is like a quagmire on the battlefield.

Falling into the mud may be a matter of spending a little time and wasting some engine troops and energy to climb out in peacetime, but once you are in a state of engagement, it is almost a passive place to be beaten. The center and right flank of the defensive line are interlocked. The asteroid belt in the middle is a natural barrier.

The dense asteroid belt cannot pass a large number of warships at once. If a battleship crosses the asteroid belt from west to east, the formation will be broken up when it enters the asteroid belt. Without formation, the scattered battleships will encounter a head-on attack from the defending fleet as soon as they emerge in the asteroid belt.

Moreover, once the middle lane is attacked, the right flank fleet will be able to force a short jump through the planet's gravity within half an hour to reinforce the central No. 2 airspace.

This meant that in order to break through the central line of defense, the enemy would theoretically have to be prepared to sacrifice more than five times as many troops.

The center and the left flank are easy to defend and difficult to attack. Then, the only weakness of the entire defense system may only be the right-wing theater itself. The central and left flank fleets need more than two hours to reinforce the right flank, and the right flank itself is not as bad as the geographical conditions of the left flank battlefield, so a direct attack on the right flank is the best way to destroy the entire strange line. However, in real combat, this is not the case.

The right flank defense will not stay where it is all the time waiting for the enemy's attack. They will use the gravitational pull of the planet in the defense zone to move at high speed, and the moment the enemy appears, they will break through to the enemy's flank or even diagonal rear, seize the attack position, and launch an attack.

In this situation of preemptively occupying the attack position, the ratio of the loss of the battleship will even reach 1 to 10!

In the last exercise, the 23rd Group Fleet and the 25th Group Fleet chose the right flank as the main direction of attack. Among their twelve A-class fleets, except for two fleets each on the left flank and in the middle airspace to contain them, the remaining eight A-class fleets were all pressed into the airspace on the right flank. And it turned out to be a fiasco.

In the first round of battle, the defending troops, who were already fully aware of the spacer airspace, moved to their left at high speed as soon as they entered the defense zone. Before they could adjust the bow of the ship, a salvo of missiles and energy cannons had already landed on their heads. This round of attacks directly caused the confusion of their formation and a large number of ships being judged out.

In the next few rounds of fighting, the attacker was still at a disadvantage, and it was not until the fifth round that the attacking position was finally grabbed. The first salvo since they entered the battlefield was launched. However, at this time, the defensive rhyme, the team, has begun to retreat. At the same time, there were also defensive fleets on the center and left flanks.

When several defensive fleets, which had suffered almost no losses, retreated to the defensive range of the fortress and threw themselves into a counterattack with the support of the fortress's firepower, half of the forces of the 23rd and 25th fleets, which were responsible for the offensive mission, were already on the list of killed in the exercise director's office.

That battle left an extremely deep impression on the three people in the reconnaissance ship. Therefore, they simply couldn't figure out what kind of confidence a bandit army with only an A-class fleet and five aircraft carriers had to magnetize this hard stone! "In our central airspace, I'm afraid we won't be able to fight any battles this time." Observer Pete stretched, looked up at the monitor above, and said lazily. "Huh?" The yellow-haired soldier on the side suddenly pointed to the telescope screen in surprise: "What is that?" "What?" The observer and the pilot turned their heads quickly.

On the screen of the telescope, a black unidentified artificial flying object, not much bigger than an egg, flashed by. Immediately, another one. A moment later, thousands of black eggs came in the sky. The observer looked at the radar, radar and other detection instruments in horror and did not react in the slightest!

"Alert the fleet." Before the observer could finish speaking, he saw countless eggs suddenly eject and turn into flying and circling saucers. At the same time, the lights of the electronic devices in the cabin flickered, emitting a series of sharp and piercing noises. The indicator light of electronic interference soared all the way, and after a few moments, it had already rushed to the top.

Looking at the red light, the three Feiyang soldiers only felt that their hearts seemed to sink to the bottom of cold water, shocked and helpless. The television device continues to work.

The surrounding satellites have turned into stones that cannot communicate after violently trembling. In the distance, an A-class fleet and three space carriers have already appeared. "Is there any news from the front?" "Where is the bandit fleet?" "Why hasn't there been movement for so long?

In the hall of Skynet, the generals watching the battle exchanged words one by one. Half an hour has passed, and according to the scheduled plan, the first contact between the two sides should take place at this time. However, the Red Army, which was the main point of view, did not find the slightest.

The satellites, reconnaissance ships and patrol ships arranged at the front of the line of defense did not detect anything unusual in the slightest. The bandit fleet seems to have disappeared from the universe. This is, after all, just a drill, not a real campaign.

In the acting plan, the bandit army does not need to break through the several lines of defense in front of the Manxia Nebula Corridor, nor does it need to occupy several strategic points in the corridor.

They only need to sail outside the surveillance range of the 32nd Army fleet and start the operation. But now, ten minutes after the scheduled contact time, there is still no movement.

Because the director's department, which is dominated by the defenders of Fiyan, cannot switch perspectives until the Blues take action, no one knows what these Fiyan "enemies" are doing at the moment. This silence made the generals watching the battle feel a heavy pressure.

The bandit army is not the Binarte Empire. But the tension was still strong as they came from the west, ready in the darkness to stab their swords and test the strongest shield in everyone's mind. Perhaps, Fei Yang has been proud for too long.
