Although some of those defense facilities have been manufactured in advance, even so, the workload is still very large.

It is really not an easy task to achieve a certain scale within a limited period of time.

Zhou Yi can only do his best now.

After retreating to a specific location, Xisen directly asked the earth mage group in the royal mage group to join forces to launch a large-scale fourth-level earth cracking spell, which directly forcibly cut off the path of the zerg army, thereby blocking it.

The pursuit of the zerg army.

However, it has been confirmed before that even those insects that do not have the ability to fly can basically fly over walls.

Climbing the rock wall is easy for the Zerg. Such terrain destruction makes it impossible to stop the Zerg army from pursuing them. At most, it will only delay the progress of the enemy's pursuit.

Of course Sisen knew this too.

But Xi Sen still doesn’t mind if he adds a little more fun to the other side...

With this idea in mind, a series of high explosives mixed with a large number of special incendiary bombs were thrown into the huge cracks in the ground.

The violent explosion impact caused the ground to tremble slightly.

Immediately afterwards, terrifying fire burst out from the cracks in the ground and completely burned.

However, Xi Sen's army did not even look at such a spectacular scene. They maintained the highest efficiency and retreated all the way, returning to the first place of their civilization of all worlds on the planet as quickly as possible.

At base!

Before the zerg army comes over, replenish supplies and recuperate.

In this state, every second is precious.

At the same time, for Zhou Yi, the withdrawal of the frontline army was equivalent to giving him an ultimatum. According to this rhythm, the insect army is probably not far away from here...

During this period, Zhou Yi tried to send out several unmanned reconnaissance aircraft to investigate the situation there.

But without exception, several unmanned reconnaissance aircraft were all attacked by the opposite Zerg air force, and eventually ended up self-destructing.

However, some of the image information transmitted back before the self-destruction still gave Zhou Yi some information.

The ground forces of the zerg army were restricted by the Earth Fissure spell and incendiary bombing, and were temporarily trapped, blocking their pursuit.

No action can be taken within a short period of time.

Under this premise, the air troops on the Zerg side did not dare to pursue them alone.

In view of this situation, Zhou Yi wanted to add fire to the opponent.

But it's obviously not that easy.

The air forces on the Zerg side are now all entrenched in the sky above that area. They are strictly guarded against them and there is basically no chance.

The planet landing battle has reached this point, and they have actually roughly decided on the next plan before the war begins.

However, in actual combat, adjustments must be made based on the actual situation at the time.

It was impossible to completely copy the original plan established in their tactical meeting at that time.

Based on the limited information fed back by the unmanned reconnaissance aircraft, Zhou Yi probably already knew the next tactical arrangements.

Before the zerg army came over, he had to seize the time to confirm with Xi Sen. Only then could the two of them cooperate and understand each other better.

And during this period of time, the insect army that had been cut off by the Earth Splitting Technique gradually passed through the huge cracks in the ground and began to continue to advance towards them.

Calculate the distance accurately, and as soon as the opposite side enters the firing range, the missile positions that have been spread out at their frontline base will fire directly in conjunction with the magic fleet in the air!

These missiles are not equipped with nuclear warheads, but they are not conventional warheads either.

Instead, in response to the situation of the insect army, let the dwarves specially prepare incendiary bombs!

Incendiary bombs are used to defeat the zerg army, and their advantages are very obvious.

Basically, if one is smashed down, the fire will burn a piece of Zerg to death.

It is a very useful weapon of large-scale destruction.

But it is precisely because of this that after the armies of both sides are completely fought together, there is no way to use it.

Unless you want to burn yourself to death too...

The zerg army on the opposite side was obviously prepared for their long-range missile attacks.

After fighting for such a long time in the previous battle, the stance bugs had already recovered a lot of energy. Now, after receiving the order from the zerg commander, they quickly opened their biological stance again.

All the incendiary bombs that fell like raindrops were blocked from the biological stance.

The attacks of incendiary bombs were all blocked by the opposing creatures.

This situation is not that unexpected.

Zhou Yiyi seemed very calm in his entire state.

Nowadays, their civilization of all realms still has a relatively sufficient output distance.

Before the zerg army completely overwhelmed the situation, he didn't mind spending some mass-produced missiles to consume the energy of the opponent's biological stance.

If we really have to calculate this account, no matter how we calculate it, it is impossible for them to lose.

Maximize the reloading speed directly, and throw the specially-made incendiary missiles at the opposite side as if they cost nothing.

At the same time, in order to increase the consumption of biological stance, Zhou Yi also began to consciously mix mushroom bombs into missiles to increase the output.

The insect army opened up the biological stance and advanced against the bombardment of civilizations from all over the world.

The biological stance can withstand it for the time being and has not exploded, but this does not mean that the Zerg will have an easy life.

Accompanied by a series of roars and explosions, the serial explosions directly caused considerable damage to the zerg at the forefront of the zerg army.

This was exactly the 'thoughtful little gift' that Sisen left for the Zerg when he commanded the army to retreat, called a sensor mine.

Due to limited time, the induction mines were not well laid out.

Even if it were to be replaced by a serious human army, I am afraid that they would soon find out that they would not be tricked.

However, the zerg army is obviously a special case.

Those who rushed to clear the way for the zerg army were basically the low-level zerg at the bottom of the zerg civilization.

Low-level bugs basically have no ability to think independently. To put it bluntly, they have no brains.

They can't see these things.

Then I went straight up...

Sisen's set of 'thoughtful little gifts' made the Zerg army move forward vigorously.

Even if I realize it later, there is actually no good solution.

Due to different civilization systems, the Zerg do not have the ability to defuse bombs.

After the discovery, the only thing the Zerg Commander could do was to send a small number of worthless low-level Zerg in a line, go up and use their lives to trigger the mines, and destroy Sisen's mine traps.

Originally, the induction mines of their civilization could be controlled manually.

But this time, because they didn't have a field of vision, they couldn't confirm the specific situation anytime and anywhere, so they simply let nature take its course.
