In this way, the defense forces of the Expeditionary Force have been completely on the front line and have formed a strong attack advantage against the assault forces of the enemy.

Immediately afterwards, the 400 engineering motherships that were confronting began to turn around and return.

Because the original cluster fleet was enough to defend against this front. Now the anti-gravity inside the center of the black hole is empty and has no effect.

The 200 engineering motherships that turned back were turned on. They started immediately and replenished energy for the second time. Because the anti-gravity channel was just established, a large amount of ore energy reserved on the engineering motherships was consumed.

Now they have to replenish before they can start emitting frozen light.

According to Lin Dong's order, the defensive front is not allowed to attack forward. The main function of the defensive front is to cut off the connection between the planet 450 and planet 439 and the dual-system planet.

And they wanted to capture these 400 attacking motherships. So the fleet continued to strengthen defense and blockade on the front, and the enemy's drone fleet came to attack.

The enemy's attack mothership launched about half of the number of carrier-based drones, which were about 200,000.

Another second round of attacks launched against the troops of the Expeditionary Force on the front line.

The troops on the planet 439 are assigned to the Lindong main fleet, so they can only barely engage in two-line battles.

Of course, it was in a situation and was very critical. Because it was on the rear base of the main fleet of the Lin Sect.

It has already arrived on the channel line toward the Hexagram Planet and emits a huge anti-transmission interference beam.

This made Clark at the headquarters of Hexagram unable to emit light and withdraw all his troops on the three planets to the Hexagram Front.

But Clark didn't dare to send his reinforcements to reinforce.

Because there are three squadrons in front of him, and at least virtual fleets with a number of virtual fleets that exceed two fleet clusters.

In Clark's view, this is two kicking fleets, plus three independent squadrons. This group has at least more than 3,000 attacking motherships and 2 million drones.

Faced with such a powerful and huge fleet cluster, Clark did not dare to relax at all.

Therefore, he did not dare to shake his first line of defense at all. The 1,000 attacking motherships above can only be legendary, in the entire Hexagram and Mishima defense line.

But this happened to be what Lin Dong needed him to do. Therefore, Shang Lin Dong's main fleet began to perform a second Yang Move outside the defensive front of the Hexagram.

The three real squadrons began to carry out feint attacks toward the outside of the quadrilateral front. The defensive front at the Hexagram headquarters was signed. Clark was not determined to send reinforcements to attack Lin Dong from behind.

In fact, Lin Dong's central main fleet cluster was actually sandwiched between the defensive front consisting of .439 and the double-line planet and the four-sided defensive front of the hexagram.

Although this distance exceeds five light years, in the era of fleets with the ability to travel through, such distances can only be achieved by crossing twice.

So in fact, Lin Dong is now being double-teamed.

Therefore, Shang Lindong urgently needs to immediately break through the defense system of the planet 439 to conquer the planet 439 and completely tear open the defense system on the back.

So Lin Dong mobilized the main force of his first fleet cluster to the front of the attack 439 front.

500,000 drones and 1,000 attacking motherships began to launch fierce attacks on the surface of the planet...

The 500,000 drones first launched 1 million unattended missiles to strike 200,000 drones that faced the front.

The ratio of 1 to 5 is more than 5. The active attack missiles have the highest effective attack capability. Then, soon these attack missiles divided the enemy drone fleets on the front.

Then the attack missiles began to destroy the drones one by one.

Soon, 200 rear attack motherships began to continue reinforcements. The drone fleet in front of them were dispatched from the attack mothership.

About 100,000 drones were found.

This is almost half of the total number of drones they carry. The remaining half is left to keep themselves for passive defense.

Then, 100,000 drones came up with reinforcements rushed into the encirclement established by active attack missiles.

The battle with these active attack missiles began to lose to death.

However, the attack missile soon pulled out another growing encirclement, and the 100,000 drones that were reinforced were also tricked into it.

Behind the attack missile is the drone fleet of the expeditionary force arranged in an array.

They have no damage at all now. They have completely built a second attack line behind the house attack missiles.

Subsequently, these attacking troops launched a second wave of active attack missiles again.

This is another 1 million. Active attack missiles. The second wave of active attacks had already bypassed the front line and directly crossed the double-teamed behind them.

Now Lin Dong doesn't care about these drones on the front. Their main uses their own active attack missiles to eliminate the 100,000 drones behind the reinforcements of Shanghai.

This million did not take the initiative to attack and planned to bypass the front of the front line.

From behind, we entered the line of 100,000 Free Army drones that came reinforced.

A random 1 million did not actively attack the missiles, and once again cut and surrounded the 100,000 drones.

Basically, the ratio between the two sides' lines is 5 to 1 or above.

The ratio of 5-to-1 attack missiles to attack drones can give attack missiles a full chance.

Taking advantage of one's own quantity advantages will avoid the problem of mechanized guidance that the guidance is too focused.

Because the frequency of the missile locked reflective wave is generally set at the saturation number, which is more than 5. That is to say, when there are five missiles that do not actively attack and lock a drone at the same time.

The locking waves they reflect will be transmitted to other active attack missiles.

Other active attack missiles will no longer fire locking waves to lock this drone.

Only in this way can drones fight missiles when they need their own and actively attack missiles, which can improve their intelligence and maneuverability.

Otherwise, active attack missiles cannot use small tactical battles in front of intelligent and very high-level drones.

Drones can completely use self-sacrifice to attract more active attack missiles. Such a drone can even absorb thousands of locking waves without active attack missiles.

Although the drone was shot down, these more than 1,000 missiles lost the opportunity to attack other drones.

In that case, the probability of losses when actively attacking missiles and attacking drones is too high. It cannot achieve any effect and effect of counterattack.

Therefore, the current combat method is to exceed the 1-5 limit. As long as the 1-5 lock limit is reached and actively attack the missile, it will no longer attack the same target.

So these drone clusters surrounded by segments took their own sacrificial actions. A small number of their drones flew in a fixed direction.

And it deliberately asked the entire missile to attack itself on the front, so that it could absorb a large number of attack missiles to lock the target.

To alleviate the pressure of other drones being locked and surrounded.

However, it is because of the five missiles that lock the target limit. A very small setting is made, which makes it possible to actively attack the missile, greatly improving the effect of intelligence and target locking.

Therefore, the drones that were on this team were quickly besieged by about 100 missiles and were finally destroyed.

The dual-system planet also encountered a drone strike from the Third Combined Fleet cluster of the Expeditionary Force head-on.

Third, the joint fleet cluster. This strike mission is to completely fight back the reinforcements sent by the Shuangxi Planet that were ready to cross the front.

Moreover, the Third Fleet Cluster will exert more powerful attack pressure on the surface of the dual-system planet.

Or the fleet of two-system planets can defend comprehensively.

It cannot be carried out any further, and the number of planet 439 is increased. This will achieve the complete isolation of planet 439.

Therefore, the Third Fleet cluster used the most powerful attack power. The 500,000 drones brought four of them to actively attack air-to-air missiles.

All of them are launched at one time. Although the drone can replenish four new air defense combat missiles in the aircraft for the second time within a certain period of time.

This time node will be extended by at least one hour. Therefore, it will take at least 1 to 2 hours after the drone launches four active attack missiles.

This long-range attack interval can only be used to defend and attack. At this moment, they do not have active attack missiles on them. There are only four long-range missiles for ground attack.

The 500,000 drones launched a total of 2 million, but did not actively attack missiles. Moreover, these attack missiles were in a fan formation and rushed forward directly.

The dual-system planet understands that if its drone fleet is still sticking to the previous combat plan and traveling through the front of the expeditionary force.

Then this is a fleet of 300,000 reinforced drone vehicles, which will be completely submerged and destroyed under a large number of active attack missiles.

So they no longer use this tactic.

Although the Free Army drones cost about 100,000 yuan were wiped out by attack missiles.

The remaining Free Army's drone fleet immediately turned around and returned to its own dual-system planet for surface defense.

Because now the 500,000 drones in the Third Joint Fleet cluster in Lindong have begun to press onto the surface line of the dual-system planet.

There are only 200,000 aircraft left on the Double Happiness Planet, and drones are defending in the air. There are 200 attacking motherships behind them. Then they ejected all of their 200,000 drones.

The number of drones' fronts increased to 400,000, Jia Yi fought against the 500,000 from the front and Jia Yuan's expeditionary army's drones.

At the same time, 100 of the attacking motherships returned to the planet and began to perform rapid resupply. About 900,000 drones launched fierce battles on the outer surface of the dual-system planet.

Without active attack missiles, the Expeditionary Force's drones and the Free Army's drones fell into ordinary combat methods.

Both sides compete for the advantage in quantity. Because they went to the active attack missile, the drones of both sides were almost equal in quality.

So in this way, the drones of both sides began to catch and fight each other. In this case, the total number of drones in the Expeditionary Force was more than 500,000.

More than free vehicles, the drone fleet has at least 100,000, which has formed a certain combat advantage. Therefore, 50,000 drones are used as mobile formations, interspersing back and forth between the two sides at multiple angles.

The purpose is to disrupt the combat front formed by the opponent's drone fleet and completely cut and divide their combat fronts.

This forces the Free Army. The drone fleet cluster can only retreat to the rear front, regroup its drones, and form a new front.

In space combat, whether it is a drone fleet, an attacking mothership fleet, or an independent combat fleet, it must be formed into a formation and then adopt a formation method to fight against the opponent.

If the opponent breaks through the formation and implements a style of cutting, your own fleet will appear at a certain base point and be hit by multiple angles and multiple flights.

Because the universe is so large, it is impossible to have a rapid border increase. So once it is divided, the situation will be very critical in the future.

Therefore, when the space fleet is fighting, they always use formations. Try not to be dispersed by the opponent, so that interactions and personnel increase can be carried out at a certain distance between each other.

Under such a powerful blow, the drone fleet of the dual-system planets could not resist the attack of the Expeditionary Force's drone fleet.
