Chapter 4449 Sweeping
A period of time passed, and as the expeditionary army completely lost the trace of the Zerg, the dominance of this war was gradually transferred from the Expeditionary Army to the Zerg.
The Zerg side should have discovered that they are building defensive facilities on the outskirts of the universe, preparing to form a defense line.
Of course, the Expeditionary Army didn't intend to hide it. Border fortifications, such a huge project, are completely unrealistic to hide.
Under this premise, it is obviously impossible for the other party to allow them to carry out this large-scale project in such a leisurely manner.
Unsurprisingly, a harassing army of zergs quickly attacked.
After the harassing troops approached to a certain distance, needless to say, with a signal, the troops ambushing in the surrounding void all released their mimetic camouflage and surrounded and killed them.
That battle was directly to prevent the harassment troops from attacking from coming back!
However, as an old opponent who has been fighting for so many years, just like the generals of the expeditionary force knew Balsa, Balsa already knew their methods very well.
Almost at the same time as the ambushes appeared on the opposite side, accompanied by violent spatial fluctuations, huge centipedes quickly emerged from the cracks in the space.
It is the strategic unit from the Void Zerg, the Void Centipede!
The purpose of the Zerg side is very obvious, which is to destroy the defense facilities that are being built by the expeditionary army and curb their move to deploy the defense line.
The destructive power of the void centipede on this type of facility is astonishing.
Basically, as long as it successfully protrudes from the face, the huge body will be swept away, and the defense facilities under construction will definitely be turned into wreckage.
But this time, in order to achieve the goal, Balsa obviously sent heavy troops.
At the same time that a large number of void centipedes appeared, a larger attack force also swept in from the outer void.
At that moment, on the expeditionary force's side, the external defense line that was being built was alarmed.
At the critical moment, Dominic Adolf hurriedly gave the order to direct the void mobile fortress of the Black Iron Empire to go up as fast as possible.
Relying on the connection between the fortresses, a temporary line of defense is formed. While protecting the defense facilities under construction, the firepower of the fortresses is used to suppress the incoming insect swarm.
From the point of view of losses, with such a long distance to the rear, even with the help of fixed space doors for efficient movement, it would take a lot of time to transport each batch of large defense equipment here. and manpower and material resources.
If the Void Centipede on the opposite side was twisted two or three times, their losses would be great.
From a strategic point of view, building a line of defense on the periphery of this universe has great strategic significance for their expeditionary force.
It is no exaggeration to say that as long as this line of defense can be built, their expeditionary force will be able to gain a firm foothold here and become the greatest confidence in their front-line operations!
Therefore, even if they pay a little more at this stage, they still have to stop the Zerg side from destroying their line of defense.
Of course, having said that, the actual implementation is not as easy as it sounds.
After all, it's not just them who are really moving...
One attack and one defense, a new round of battle between the armies of the two sides will soon start completely.
During this process, Bemon, as the top combat force of the Void Zerg, did not show up on the battlefield.
Correspondingly, Xu Yu did not show up for the expeditionary army.
In the previous long battles, the number of times Xu Yu and Bei Meng fought was actually very few, and they were generally concentrated in the early stage.
In the middle and late stages, the top combat forces on both sides have basically entered a state of 'the enemy does not move, I do not move', forming a subtle mutual check and balance.
In the tactical meeting on this matter, Xu Yu believed that his strength was higher than that of Bemon, but if he wanted to kill him, he might have to spend a lot of effort.
Under this premise, if the two sides are fighting, if Xu Yu strikes first, then the opponent can directly let Bemon avoid Xu Yu and attack the troops on the other side.
Xu Yu herself was not good at body speed. Before she arrived, according to Bemon's strength, she might have been able to cause enough damage to their expeditionary troops, and then burst out and walked away.
Under this premise, it's not that the expeditionary army has never thought about asking the Yanhuang Empire to send more top-level combat forces.
However, their request is somewhat difficult.
The Sifang God Generals of the Yanhuang Empire, also known as the Four God Generals of Zhenguo, can be seen from this title, the main responsibility of the Four God Generals is to 'restrain the country', with guarding the country and protecting its security as the first priority. It is not easy to dispatch the expedition itself.
The strength of the four god generals can only be 100% exerted in combination with the four corresponding terrains unique to the Yanhuang Empire. Once they go out to fight, their strength will be limited to a certain extent, which is also one of the reasons .
This time, he was willing to send Nanhuang Lord Xu Yu to the expedition. On the one hand, Xu Yu took the initiative to invite Ying, and on the other hand, it was considered to be for the sake of Ye's Chamber of Commerce. Considering the relationship between them, they gave Tianda a big face.
Furthermore, even if the Yanhuang Empire is willing to send more combat power, who can guarantee that the other side will not have it?
Since there is a Belmont on the opposite side, there is a high probability that there will be a second one.
Both of them obviously couldn't figure out how much top combat power the other party had.
Therefore, this finally formed a situation where no one dared to act rashly...
In this wave of attacks, the main purpose of Balsa was to destroy their fortifications, and he didn't intend to fight them directly here.
After fighting for a while, the Zerg army retreated in an orderly manner.
From this point, the expeditionary army can roughly guess that the opponent's follow-up reinforcements may not have reached the front line.
Assuming that the reinforcements have already arrived, what is there for the commander on the other side to wait for? It is normal to press the army directly.
Only when the reinforcements have not arrived, the opponent will use this kind of small-band harassment to interfere and slow down their deployment of the defense line.
Facts have proved that they guessed right, the Zerg side chose the small-band harassment tactics without any surprise.
But even in the case of guessing the opponent's actions, they have to admit that such methods are not afraid of being guessed or seen through.
Because no matter what you do, the other party's interference goal has already been achieved.
And the fact is indeed the case, the actions of the Zerg side have actually constituted interference to them, and the efficiency of their defense facilities has been greatly slowed down. Attacks continue to increase...
