For the sake of caution, the vanguard assault fleet in the vanguard army had already maintained its mimic camouflage and launched an offensive formation before it even approached the battlefield.

And maintaining this offensive formation, it approached the target position in a slowly gliding manner.

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

In this type of mission, this vanguard assault fleet is undoubtedly experienced, which allows them to successfully enter the battlefield and continue to approach the target Zerg planet.

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

This is because the defensive strength of the planetary defense line on the Void Zerg side becomes sparse the further outward it goes.

This point is actually the same for any racial force.

After all, the further the position is pushed outward, the larger the area that needs to be defended and the higher the difficulty of defense. Even the Void Zerg, which is famous for its terrifying troop scale, does not really have endless troops. Therefore, in every Appropriate choices must be made after careful consideration in the deployment of troops in the defensive circle.

Not to mention, in the current situation, they are only passively defending.

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

Under this premise, if they continue to mobilize large-scale forces to perform defensive tasks, it will result in their army being unable to get a relatively adequate rest.

This is undoubtedly not conducive to their ability to cope with the upcoming battle.

In this way, even the Void Zerg chose the more classic "loose on the outside and tight on the inside" style of defense.

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

Needless to say, after the army retreated, Balsa, who officially took over an entire army, undoubtedly had an in-depth understanding of the entire battle situation through the brainworm commander of the previous frontline army.

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

In that battle, they suffered heavy losses in strength.

With such a painful lesson learned from the past, after taking over the position of 'Commander-in-Chief' of the frontline army, Balsa naturally took further precautions against this area. It was impossible to let the Void Zerg army be in the same pit. Fell in again.

After reaching a certain distance, the density of the entire defense circle began to rise linearly.

When you get close to this distance, you can already see the position of the opposite planet from a distance, but the distance is obviously still far away.

From this position, it is very difficult to raid the opposite planet in a short time.

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

The mechanical clan's reconnaissance shuttle could only detect this location before, and could not go any deeper...

It may be a little inaccurate to say this, but it doesn’t mean that there is no way, but that an exposure risk must be taken into consideration.

After all, judging from the defense density, if the distance is further pushed forward, the chance of being discovered by the opponent will rise linearly. If you are not careful, their existence will be exposed and they will fall into a passive position.

If a reconnaissance shuttle with excellent concealment capabilities is like this, can the huge interstellar battleships be better hidden than a reconnaissance shuttle?

This is obviously impossible.

But even so, the Vanguard Army must try to close the distance with the opposite Zerg planet as much as possible, and in the process, find a suitable breakthrough from the Zerg defense circle.

From the current point of view, this operation is going relatively smoothly. The Zerg deployed in the defense circle on the opposite side have not yet discovered their existence.

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

Anyway, the further they push, the more advantageous it will be for their subsequent raids after their whereabouts are exposed.

However, this smooth situation made Liu Meng, the commander-in-chief of the Pioneer Army, frown slightly.

He always felt that something was not quite right...

At the same time, as the commander-in-chief of the first expeditionary force, Zhou Yi undoubtedly shouldered an important task in this operation.

For this reason, Zhou Yi, who was in the general command room, had already begun to synchronize the intelligence information returned through the tactical system while the vanguard army was launching operations, and began to pay close attention to the situation ahead.

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

"The zerg has discovered you! Hurry and retreat!!"

There was not even a polite word. The moment the contact was connected, Zhou Yi raced against the clock and said that sentence as quickly as possible.

Liu Meng's heart twitched when he heard these words. Combined with his previous hunch, Liu Meng hurriedly issued a retreat order without saying a word.

And almost at the moment they made the retreat, the army of insects that were still there on normal alert and patrolling suddenly burst into flames and immediately formed a wave of insects, sweeping towards the vanguard assault fleet that was trying to evacuate!

"Hell, fire!!!"

During the previous evacuation of the Vanguard Assault Fleet, they still maintained their mimic camouflage.

As a result, as soon as they withdrew, the Zerg immediately showed its true colors. This undoubtedly showed that the current situation was completely correct by Zhou Yi. Those damn bugs had already discovered them! They were just following them before.

They act!

When the attack order was issued, the vanguard assault fleet immediately began to evacuate at full speed. At the same time, the fleet's firepower quickly burst out.

Although the firepower output of the Vanguard Assault Fleet is far less powerful than the regular firepower fleet, it is more than enough to deal with the zerg that are currently besieging them.

However, in this wave, the Zerg discovered them early and undoubtedly made plans in advance.

Under Zhou Yi's reminder, although the vanguard assault fleet was aware of this in time, it may not be that easy to escape unscathed now.

Sure enough, the insects that were ambushing in the surrounding void began to attack one after another at this moment.

At the same time, in the external void, along with the distortion of space, huge void centipedes and void earth-boring insects quickly entered the battlefield. It was enough to see that the opponent's preparations for this wave were quite sufficient.

At this moment, he was in the command room of the rear fleet. Although he had guessed the opponent's plan, Zhou Yi's face was not pretty. His expression was solemn, and his two eyebrows were almost twisted into a ball.
Chapter completed!
