The Invincible Overlord of Heroes.

If the elves were to build a city seriously, the model would not be much different from that of humans.

The correct process is to lay the heart of the city first, and then rely on the heart of the city to quickly build various buildings.

However, each camp also has its own characteristics.

For example, the characteristic of human beings is that they can modify various buildings, including heroic buildings, by relying on their own construction art.

The characteristic of the undead is that they can rely on a large number of corpses to extend the control range of the city's heart.

For example, the dark sky buildings that were destroyed by Xu Lai. These buildings could be built in large numbers at the same time because they relied on the heart of the cemetery city.

Demons have the ability to transform cities, dungeons can dig underground passages, and elves can build mobile cities.

It is called a mobile city, but in fact it is a tree-shaped city built by imitating the structure of the world tree, relying on ancient tree people who can walk.

Humans are also good at building tree houses, especially those on large trees, and it is common to build several tree houses.

Even humans can build tree houses, and the elves have druids who can communicate with trees and make them grow.

They even have ancient tree spirits that have grown for tens of thousands of years. Even if they shrink their bodies and walk, they can easily reach a height of 3 meters.

After these ancient tree spirits sit down, they stretch out their branches and roots completely, easily covering an area of ​​hundreds of meters in radius.

Of course, this is not enough to build a city, at best it can only be regarded as an elf village.

But it doesn’t matter, that’s just the ability of the ancient tree spirits themselves.

If they are given enough energy, they can extend themselves indefinitely.

Theoretically, as long as there is enough energy, the ancient tree spirits can grow to an existence second only to the World Tree.

Now, the elves plan to use this method to quickly build a city.

I saw the largest and oldest tree spirit surrounded by a group of ancient tree spirits. It tightly wrapped around the heart of a fortress city and sat trembling in the soil.

A high-level Heart of the Barrier contained a large amount of energy. With the assistance of the Druid, it would soon be possible to build a tree city covering thousands of kilometers.

The price is that this ancient tree spirit that has grown for ten thousand years will be completely connected to the city and will no longer be able to move.

If the elves accidentally lost the city, the ancient tree spirit would also lose its life.

And because of its integration with the ancient tree spirits, this city's upper limit, territory and control range are much smaller than other cities.

This is a living city after all. Cities can expand infinitely, but life cannot.

As powerful as the World Tree is, it can only expand to the entire Emerald Forest at most. Although it is already extremely terrifying, there is only one World Tree after all.

After the ancient tree spirit sat down, its body, which had been closed, gradually opened.

Druids continue to release the most powerful life spells to promote the growth of the trees.

And the large amount of dead energy that was originally accumulated by the undead in this place was quickly dispersed under the impact of this huge life energy.

The group of priests brought by Dur did not follow them out of the city, but Dur still followed the elves in the important event of building the city.

It didn't matter that there was no other priest around. Under his quiet prayers, rich holy light descended from the sky, quickly purifying the dispersed deathly air.

Death is not always a bad thing.

In this battlefield where the undead and the elves have been fighting for who knows how long, there are countless corpses hidden.

And life is usually born with the nourishment of these corpses.

Xu Lai didn’t know whether the undead could hold back, but if it were him, he definitely wouldn’t be able to hold back.

Once the elves' city is completely established, the vast tracts of land around it, especially those still shrouded in the dark sky, will be controlled by the elves again.

No one knows how many mobile cities like the Elf there are.

If it is not contained immediately, the elves can continue to take over in this way until they recapture the original city.

Similarly, Modo didn't want to see this scene.

Not only was he worried about the elves retaking the city, he also had pressure from Sandro.

So not surprisingly, the undead set out again before the elven city was completed.

Before, Modo chose to avoid Xu Lai because he knew that with Xu Lai's group of terrifying high-level knights and Seraphim, even if those ordinary undead were exhausted to death, they would not be able to break through the defense.

The key is that the group of knights can come and go as they please, and he has no way to restrict them.

On the contrary, once Xu Lai seizes the opportunity, he will most likely be killed in one wave.

Therefore, Modo simply moved away. This group of knights couldn't do anything anyway and could only destroy some of the dark sky.

Since this thing has captured a large number of elven cities and recovered a large amount of resources, you can build as many as you want without feeling sorry for it.

But now it’s different. This group of knights have something they must protect, and that also means they have weaknesses.

Ordinary undead might not be able to deal with these knights, but as long as these knights can't run away, he has a way to deal with them.

The undead have never been afraid of powerful enemies. On the contrary, the more powerful the enemy, the higher the value of the materials after killing them.

The giant dragons that most people avoid are very popular among the undead.

It was still the same old routine. The first undead to be dispatched were a large number of skeleton warriors.

Even if these skeleton warriors could get close to the elves' city, it would take them countless years to use their bone knives and swords to demolish an elven city.

There is no doubt that they are a group of cannon fodder, used to attract the elves' firepower and consume the elves' ammunition.

Seeing the undead, all the tree people began to take root on the spot and used their bodies to protect their teammates behind them.

The ranger troops that followed Xu Lai skillfully jumped onto the bodies of the tree spirits.

Thanks to the tree spirits' height of tens of meters, the damage bonus is not as good as that of the city walls, but it is still very considerable.

Of course, when dealing with these skeleton warriors, it doesn’t matter whether you have this attack bonus or not.

On the contrary, whether these skeleton warriors are worth the rangers' wasting arrows is very debatable.

So, it didn't take long before Tracy, who was temporarily serving as the commander of the ranger force, called a halt to the attack and allowed the skeletons to approach.

The skeletons couldn't get too close, because the ancient tree spirits on the periphery had already used their roots to entangle all the approaching skeletons.

Although these ancient tree spirits were recruited and have not survived for tens of millions of years, they are still level 7 creatures.

As a level 7 creature, the Ancient Gold's attack and defense are beyond words, and even these skeleton warriors cannot break through its defense even if they are exhausted to death.

Not only are they unable to break through the defense, these skeletons will also be easily broken apart by these giant trees.

But these skeletons were originally cannon fodder released by the undead, and Modo did not expect these broken skeletons to have any effect.

Their greatest function is to attract the attention of humans and elves and buy time for the real main force of the undead.

The real main force of the Undead is neither the corpse wizard that Modo specializes in, nor the strongest bone dragon of the Undead.

Large groups of slow-moving zombies began to appear in the elves' field of vision. "Oh no, they are plague zombies. Quick, kill these plague zombies first."

Under Cuisili's command, the rangers, who had just put down their bows and arrows, raised their longbows again.

This time, they did not shoot blindly. Instead, they aimed carefully and shot arrows into the heads of the plague zombies.

An elf with a long life who can constantly hone his archery skills will naturally not miss the target.

Their aiming at this time is just a simple skill in order to increase damage.

The attack power of the plague zombies is not high. At least for these high-level rangers and ancient tree spirits, it is not easy for the plague zombies to even break through their defense.

But as zombie creatures, their defense and health are extremely high.

Another terrifying feature of plague zombies is that as long as they are alive, they are outputting.

[Spread Plague]: Spreads plague to all creatures within 6 meters of itself, causing 10 damage every 3 seconds and a 10% slowing effect.

Note: If a civilian dies from this injury, they will become zombies after death.

Professionals will not die from this damage (that is, when the health value is 1 point, they will no longer take damage, but the plague effect will still remain.)
The plague will not kill the professionals, but it is a kind of damage that cannot be resisted and can only be reduced by physical fitness.

Even with Xu Lai's terrifying physique, it is impossible for him to completely resist the plague.

Of course, with his physique, he can definitely last longer than others.

Fortunately, although the plague zombies have high health points, they still inherit one of the zombies' characteristics: they are extremely slow.

Since this large group of zombies was discovered, they have been targeted by the ranger troops. Hundreds of them died before they could barely advance a few meters.

The first wave of skeleton warriors failed to steal much ammunition from the rangers. If they had to force their way through, they could only exchange the lives of the plague zombies for the rangers' ammunition.

Mordo is not distressed about the plague zombie, as the level of this thing is not very high. As long as there are enough basic zombies, the cemetery city can be upgraded.

The key is that this thing is too slow, and there is not enough to consume when transported to the battlefield.

Because the undead do not need logistics and can directly produce undead warriors in batches on the front line, they advance extremely quickly.

This leads to a very fatal problem: the replenishment of the Undead's troops is out of sync.

The several undead cities built by Sandro and his men are hundreds of kilometers away from here, with the nearest one being hundreds of kilometers away.

At this distance, dragging the zombies back and forth would take at least a week.

Even if all the zombies were discarded, the movement speed of the corpse wizards was not fast. The jungle terrain also had a speed penalty, so they could only move one day faster at best.

Even if Modo also mastered the spell to return to the city, he couldn't open a door to another dimension and fly back.

After fighting with the elves for such a long time, zombie-type troops are the only meat shield type of the undead, and their consumption is quite high.

The plague zombies that were brought out at the beginning had actually been almost used up. Fortunately, some of them were promoted on the battlefield, otherwise they would have been useless long ago.

In this situation, Modo couldn't bear the plague zombies being sniped in large numbers.

However, Modo has other preparations.

With a wave of his hand, a large number of undead rolled out large meat grinders.

The elves' jungle environment has greatly affected the use of undead siege weapons.

These meat grinders, which Modo collected in his space ring, are all of top-grade quality.

Usually, he would only use it when he encountered a particularly difficult city.

The undead's meat grinder functions similarly to humans' catapults.

However, as the name suggests, a catapult throws stones and at most has some magical effects.

The meat grinder of the undead threw away corpses, corpses that were extremely rotten.

The most terrifying thing is that the undead were fighting with the elves at this time, and what were thrown over were naturally the corpses of the elves.

No matter who evaluates the elves, they will always use adjectives like handsome men and beautiful women.

A race that was once so handsome, now soaked by the undead, is more terrifying than the giants.

Many of the bodies thrown out were those of these rangers' comrades.

However, they had no time to worry, because the corpses would explode directly after reaching their destination.

The damage is not as exaggerated as that of boulders or magic ammunition, but their effects are the same as those of plague zombies, both of which rely on the corrupted death energy to corrode creatures.

Wherever the rotten meat is blown up, the plague will spread and no living creature will be able to survive there.

Of course, the rotten flesh cannot continue to spread, but it is fine if it lasts for about half an hour before being purified.

If it needs to be purified, it can only be done by a priest, or someone can find the rotten substances and pour holy water on them.

The ranger has no choice but to leave the plague point, otherwise he will be stuck here forever.

Fortunately, all the tree spirits have taken root underground, although they still have to suffer damage unavoidably.

But after taking root, they can continuously absorb nutrients from the earth and accelerate the recovery of vitality.

The damage caused by this little bit of plague and death is not even half of their recovery ability, and it is completely unable to harm these big trees.

Xu Lai and his knights were the main targets of the undead.

After all, these meat grinders are siege units and their attack range is very long.

Moreover, as a siege equipment, it is also the best in Modo's collection. Even if the ranger takes the half-arrow penalty for being out of range and shoots at the meat grinder, he can't gain any advantage.

Unfortunately, one of the worst things Modo did was to provoke Xu Lai.

The catapult is not like a Moto. This thing has a large target, and the key is that it keeps firing.

Elvy brought a group of angels with her, cast a few simple blessing spells, and soared into the sky.

Xu Lai also drew out the sword in his hand at the right time, and suddenly countless holy lights scattered in the sky, covering the heads of every elf.

The holy light failed to dispel the plague, but it dispelled the elves' fear of the plague.

In the past, the undead had taken over countless elven cities by taking advantage of these irresistible plagues.

But today, inspired by this holy light, they finally gritted their teeth.

The plague is something that causes damage relatively slowly. The key is that once a place is infected with the plague, no matter how many plagues there are, they will not be able to cover it.

That is to say, the damage of this thing does not stack.

As long as the ranger can overcome the fear of the plague, he can actually survive for a long time in the plague.

It doesn’t matter if they can’t hold on. Xu Lai went out to build a city today, so he pulled all the Holy Light Knights out.

Plus, there are hundreds of druids and a Crimson Archbishop. Even without counting the life potions that the rangers bring with them, no one will die. (End of this chapter)
