For the sake of caution, the Vanguard Assault Fleet in the vanguard has maintained a mimic camouflage before it is close to the battlefield, and has spread out the offensive formation first.

And maintain this offensive formation, with a slow sliding attitude, spreading closer to the target position.

During the period, as long as the speed is slow enough, the mimic camouflage covering the surface of the hull can be perfectly maintained, without any flaws.

In this type of task, this vanguard assault fleet is undoubtedly rich in experience, which allows them to smoothly enter the battlefield and continue to approach the Zerg planet as the target.

However, this next task will obviously not be as easy as the previous one.

Because the defensive force of the planetary line of defense on the side of the Void Zerg is sparser.

This point, in fact, is almost the same after changing any racial power.

After all, the more the position is pushed, the larger the area that needs to be defended, and the higher the difficulty of defense. Even the Void Zerg, which is known for its terrifying force, is not really infinite, so in every defense Regarding the deployment of forces in the circle, it is necessary to make appropriate trade-offs after careful consideration.

Not to mention, in this situation, they are just passive defense.

In other words, they have no idea when the coalition forces will attack.

Under this premise, if they have been mobilizing large-scale troops to perform defensive tasks, it will cause their army to be unable to get relatively adequate rest.

This is undoubtedly not conducive to their response to the next battle.

In this way, even the Void Zerg chose the more classic ‘loose outside and tight inside’ type of defense.

However, the tightness of this internal defense is exceptionally astonishing.

Needless to say, after the army retreated, Balsa, who officially took over the entire army, was undoubtedly through the brainworm commander of the previous frontline army, and conducted a round of in-depth understanding of the entire battle at the time.

At the time of the battle on the frontline planets, their defeat of the frontline army of the Void Zerg began from the moment they were attacked by the opposite side and lost their dominance.

In that battle, their troops suffered heavy losses.

With such a painful lesson learned, after taking over the position of the front-line army'commander-in-chief', Baltha naturally took further strict precautions for this piece. It is impossible for them to be in the same pit. Plant it again.

After reaching a certain distance, the density of the armed forces of an entire defensive circle began to rise linearly.

Close to this distance, you can already see the position of the opposite planet far away, but the distance is obviously far away.

In this position, it is not unreasonable to make a raid on the opposite planet in a short period of time.

Needless to say, this distance arrangement must have been carefully calculated by the commander-in-chief on the opposite side.

Previously, the reconnaissance shuttle of the mechanical race only detected this position, so there was no way to go deeper...

It may be a bit inaccurate to say that, not to say that there is no way, but to consider an exposure risk.

After all, judging from the defense density, if the distance is pushed forward, the probability of being spotted by the opposite party will rise in a straight line, and if they are not careful, their existence will be exposed and they will become passive.

The reconnaissance flying shuttle with excellent concealment ability is even so. Can those huge interstellar warships hide better than the reconnaissance flying shuttle?

This is obviously impossible.

But even so, the vanguard army should try to get as close as possible to the opposite Zerg planet, and in this process, find a suitable breakthrough from the Zerg's defensive circle.

For the moment, this operation is relatively smooth, and the Zergs deployed in the defense circle on the opposite side have not been found to exist yet.

Judging from the current situation, they can at least push forward a certain distance.

Anyway, the farther they are pushed, the more favorable they will be for their subsequent assault operations after revealing their whereabouts.

However, this smooth situation caused Liu Meng, the commander-in-chief of the Vanguard Army, to frown slightly.

He always feels that something is wrong...

At the same time, as the commander-in-chief of the first batch of expeditionary forces, Zhou Yi was undoubtedly shouldering an important task in this operation.

For this reason, Zhou Yi, who was in the commander-in-chief room, had begun to synchronize the intelligence information back through the tactical system at the same time that the vanguard began its operations, and began to pay close attention to the situation ahead.

In this process of observation and thinking, Zhou Yi, who seemed to have suddenly realized something, had no time to think about it, so he quickly sent an emergency contact and got in touch with Liu Meng.

"Zerg has found you! Retreat quickly!!"

There was not even a single word of courtesy. At the moment when the contact was connected, Zhou Yi was determined to fight every second, and said that word as quickly as possible.

Liu Meng's heart twitched when he heard this, and combined with his previous premonitions, Liu Meng hurriedly issued an order to withdraw without saying a word.

And almost at the moment when they made a retreat, the Zerg army that was still on normal alert and patrolling there suddenly rose up, immediately forming a worm wave, and swept toward the vanguard assault fleet that was trying to withdraw!

"Damn it, open fire!!!"

The previous evacuation of the Vanguard Assault Fleet still maintained a mimicry camouflage.

As a result, as soon as they withdrew, the Zerg immediately revealed its true colors. This undoubtedly explained the current situation. It was completely hit by Zhou Yi. The **** bugs had already discovered them! I was acting with them before!

The attack order was issued ~lightnovelpub.net~ While the Vanguard Assault Fleet directly began to evacuate at full speed, the fleet's firepower exploded quickly.

Although the output firepower of the Vanguard Assault Fleet is far less fierce than the regular firepower fleet, it is more than enough to deal with the currently besieged Zergs.

However, in this wave, when Zerg had discovered them long ago, it was undoubtedly also made a layout in advance.

Under Zhou Yi's reminder, although the Pioneer Assault Fleet was aware of this in time, it might not be so easy to retreat now.

Sure enough, the Zerg worms ambushing in the void around them came out one after another at this moment.

At the same time, in the external void, along with the distortion of space, a series of huge void centipedes and void burrowers also quickly cut into the battlefield. From this, it can be seen that this wave of opponents' preparations is quite sufficient.

At this moment, in the command room of the rear fleet, although he had guessed the layout of the opponent, Zhou Yi's face was not good-looking, his face was solemn, and his eyebrows were almost twisted together.

In this round, they were unfavorable, I am afraid it is not easy to play...
