Luo Ji's army of civilizations from all realms obviously didn't know that the undead army had such skills.

At that time, the army soldiers who were inside the surface defense position, assisting the dwarf tank and mecha corps to resist the undead army's offensive, fell down in large areas in the blink of an eye. Their lives were uncertain, and their internal defense lines were once in turmoil.

However, Zhou Yi, who had anticipated various situations in advance, had made some preparations.

The simplest way to respond is to send additional troops to attack.

Considering the previous losses with the mechanical civilization army, the current strength of their All Realms Civilization Army is definitely incomparable to the undead army.

But a skinny camel is bigger than a horse. For the time being, their civilization can still live up to this sentence, and they won't be able to send out troops at this moment.

Especially for the troops on the planet, the previous battles and the focus of the mechanical civilization's battles were all placed on the void battlefield.

This makes the consumption of their army of civilizations from all realms on the void battlefield even greater.

But relatively, the consumption within the planet is small.

This has led to their current situation, the troops on the planet are still in pretty good condition, and their scale is basically guaranteed.

The internal space of the defensive position they now occupy is limited.

It is obviously impossible to send out all the army troops in the planet at once. This space will definitely not be able to squeeze them in.

At the same time, considering that the opponent has no physical limitations at all and is an undead army that is very good at long-term continuous combat...

Unless you are sure that you can directly defeat the opponent in one go.

Otherwise, it would be a very unwise choice to send out all the troops in hand.

Because over time, their physical strength will be affected, and their subsequent combat capabilities will continue to decline, and they will inevitably be dragged down by the undead army alive!

The best way to avoid this situation is to rotate in batches. In this way, each batch of soldiers can get appropriate rest and adjustment time in the fierce battle.

The first batch of magic infantry troops sent out were knocked down in large numbers so quickly, which was unexpected by Zhou Yi.

But it wasn't enough to completely disrupt his plan.

He quickly made adjustments to his original plan based on the actual battle situation, and the subsequent troops quickly stepped up.

During this period, the undead army also kept sending more wandering souls and resentful spirits to sweep over.

To put it bluntly, this wave is the beginning of a battle for strength.

In this regard, the Book of Changes is quite true.

At least for now, he is honest.

Through previous battles, their understanding of the undead army and the wandering souls, a series of low-level spiritual units, has become more profound, and their intelligence has been further improved.

After gaining a fuller understanding of them, and then facing those wandering souls and resentful spirits, and gaining experience in dealing with them, the battle will naturally become easier to fight.

After that, the first thing Zhou Yi did next was to quickly confirm the status of the dwarf tank and mecha legion.

The tank and mecha army of the dwarves is the core force of the civilized armies of all worlds on the planet.

If even the tank and mecha legions were severely affected by the wave of soul explosions just now, then the next defensive battle on their planet may not be easy to fight.

When thinking of this, even Zhou Yi inevitably became a little nervous.

After confirming that the dwarf tank and mecha army was basically fine, he breathed a sigh of relief.

Different from the early days when they relied purely on outer defensive armor for defense, today's tank and mecha units are not only covered with sufficiently strong defensive armor on the outer layer, but also have a 'magic magic' system of defensive techniques on the inside.

Mode.

While it can further strengthen the defense on the physical level, it can also resist some spell-level attacks.

Mental shock is undoubtedly a spell-level attack.

I don’t know if the soul blast intensity of those low-level wandering spirits is not high enough, but the dwarf pilots in the cockpit of the tank mecha were basically not affected much.

However, in this process, the undead army inevitably pushed closer and closer.

After the army advanced to a certain distance, the Lich Mage hiding in the dark began to cast spells.

At that moment, on the battlefield, countless wandering souls whose bodies were destroyed by the firepower of the dwarf tank and mecha legions began to scream ear-piercingly.

The bone fragments scattered throughout the battlefield were drawn by the power of the spell and continued to gather together.

After a large amount of accumulation, a huge and huge skeleton quickly took shape.

Surrounding this huge giant skeleton, a large number of wandering souls began to fly continuously, and gradually merged into one during the flying process, and finally slammed into the heads of those giant skeletons.

In an instant, with a muffled sound of 'bang', two huge groups of soul fire were ignited in the two empty eye sockets of the giant skeleton!

The strategic war unit of the Skeleton tribe, the Skeleton Giant, has officially entered the scene!

Now, the tactical arrangements of the undead army are undoubtedly clear.

They just want to use the skeleton army to consume the firepower of the defense forces of the civilizations of all worlds, and then wait until the distance is reduced to a certain point, and then the lich mage summons the skeleton giant, destroys the shield of their defensive position, and attacks them in one go.

Get rid of this base on their planet!

How could Zhou Yi allow the other party to succeed?

After some maneuvering, the firepower of the dwarf tank and mecha army was immediately transferred.

As a strategic war unit of the undead army, the Skeleton Giant is not particularly strong in terms of defensive strength, but rather an above-average level.

But it has a very disgusting feature, that is, as long as there are enough skeleton remains and wandering soul fragments on the battlefield, even if the skeleton giant is destroyed, the Lich Mage can cast spells to reunite them.

From this moment on, the disgusting nature of the undead army was gradually revealed in the battle.

Facing the countless skeleton army, the harder they fought, the more skeletons and ghost fragments appeared on the battlefield.

The more skeleton remains and wandering soul fragments there are, the more skeleton giants summoned by the Lich Mages.

This is simply a vicious cycle!

However, what Zhou Yi does not know at this stage is that, in fact, even without skeleton remains and wandering soul fragments, the Lich Mages can directly use complete skeleton soldiers to summon the skeleton giant.
Chapter completed!
