As the demon army moves forward quickly, fireballs appear one after another, each of which kills a major unit on the spot.

The other thing that suffered the most was the terrible soul shock, because once this thing appeared, it would kill a large number of people.

In contrast, the losses of those cannon fodder were not much, and basically all the dead were high-level heavy armored units.

This made the four high-ranking territories in the rear deeply heartbroken.

Although the demon army is almost endless, the majority of them are ordinary demon cannon fodder or demon troops.

And those special demons, such as heavy armor demons and the like, have special skills and special use of demon varieties, and the number of them is still not enough.

Because although there are many different environments in the Endless Abyss, most of the environments are still relatively ordinary environments, and can only produce ordinary demon troops.

And something like a heavily armored demon requires an extremely special environment to produce in large quantities, and this kind of environment is rare in the abyss.

In addition, heavy armor demons can also be produced in ordinary environments, but the number is very rare and belongs to special mutations.

All in all, although the special demons are powerful, there is still a certain limit to the number of them, and they are by no means endless.

It is precisely because of this characteristic that Emperor Shi Tian will strike at special demons.

In addition to the anti-tank mines specially prepared for the heavily armored demons, Emperor Shi Tian also prepared an assassination package for those high-level special demon troops.

For example, a small succubus on the battlefield, although her strength is only silver-level, but her destructive power is very terrifying, once she gets close to the city wall, she may charm the defenders on the city wall.

You must know that there are a large number of alchemy weapons piled up on the city wall, and at this time, if a traitor appears, even if it is only the lowest level of goblin, it may cause irreparable terrifying damage.

Because this goblin can put a grenade where the ammunition is placed, and then detonate it, and God knows how many people will die by then.

The most important thing is that it will lead to a lack of ammunition in one place, which will greatly reduce the lethality, and maybe the entire city wall will be lost.

Therefore, for these terrible little succubi, Emperor Shi Tian was naturally extremely cautious, and directly issued a kill order.

And these little succubi are also self-aware, they usually go to the battlefield, and they are definitely the key targets, so they have already learned to be obedient with advanced wisdom.

Basically, every little succubus will use stealth techniques and walk cautiously in a relatively safe place, at least away from those heavily armored demons who are often attacked by mines.

However, the little succubus's stealth ability has long been known to the whole world, and Emperor Shi Tian is certainly no exception.

Therefore, Emperor Shi Tian was on the city wall early, and arranged a special anti-stealth telescope, just to find these little succubi.

Once the location of the little succubus is locked, there will be a killer immediately, often a dog-headed aluminum bat with stealth ability.

In fact, there are a large number of dog-headed aluminum bats distributed on the battlefield within a radius of 100 kilometers, but they are relatively scattered and not concentrated.

These guys specialize in assassination, mainly small succubi, followed by demon warlocks, and then all kinds of low-defense law units.

After seeing the little succubus again, the dog-headed aluminum bat will quietly approach from behind, and then swoop down, control the Yuan Magnetic Flying Sword, and directly behead it.

Although the little succubus is charming, her defense ability is notoriously weak, especially in the case of a sneak attack that is caught off guard, basically one by one.

Therefore, on the battlefield, it can often be seen that one by one, the little succubi at the silver level came out of the stealth state for no reason, but they all lost their heads at this time, and when they died, they still had doubts on their faces, and they didn't know how they died.

The gold-level little succubus is more difficult, but there are also gold-level high-level troops among the dog-headed aluminum bats, all of which are the first batch of masters who have been trained.

They have also been armed to the teeth with high-grade alchemy items, especially the Natal Flying Sword, which has been cultivated to the level of silver or even gold, and if it is used for assassination, it can be called invincible.

In short, those succubus troops on the battlefield can be said to be unlucky, and they are often beheaded without knowing it, and they are so killed and injured that they can't even get close to the city wall within fifty miles.

In addition to these little succubi, some special demons with great threats are also the targets of their assassination.

For example, there is a kind of acid brood demon that looks like a cockroach and has round holes in its huge back shell, in which green eggs are hatching.

This acid brood demon is also at the gold level at worst, but its combat power is a mess, and almost no one can defeat it.

However, the Acid Hive Demon's ability to attack the city walls or castles is indeed unmatched by any of the Golden Troops.

Because this thing can attack from dozens of kilometers away from the castle walls, they will hatch their backs into rolling ball-shaped demon bugs.

Each of these demonic insects was more than a person tall, weighed a ton or two, and was filled with high-temperature acid.

They can roll quickly on the ground and then crash straight into the walls.

If there is no alchemy rune protection, even if the city wall is ten or twenty meters later, it will be pierced by a demon worm.

And such an acid brood demon can make dozens of demon insects every time, and one can destroy the front wall of a city at once.

And those alchemy city walls can't stop too many demon insects, because its specialty can damage alchemy runes.

For example, the defense of the city wall that Emperor Shi Tian is building now has been blessed to the alchemy rune of the bronze level, which can withstand a lot of spell damage.

However, if a castlevania hits the city wall, it can pollute the wall surface of dozens of meters, and then the acid will melt the alchemy runes on the wall skin, making the city wall here become an ordinary city wall.

And for powerful demons, there is not much difference between an ordinary city wall and tofu.

Any gold-level demon, with a wave of his hand, the Demon Flame can burn through the ordinary city wall dozens of meters thick.

Therefore, if a large number of acid brood demons were to be brought close to the city wall, this wall of Emperor Shi Tian would quickly be corroded into an ordinary city wall, and then easily destroyed by others.

But it was obvious that Emperor Shi Tian, who had been prepared for a long time, would definitely not allow such a thing to happen.

The slow-moving Acid Brood Demon will immediately launch a bombing attack as soon as it falls into the eye of the dog-headed aluminum bat in the sky.

For the large size of the acid brood demon, it is difficult for the flying sword to deal effective damage to them, even if it pokes a transparent hole, it doesn't matter, the demon's strong vitality can ensure its survival and continue to fight.

But don't forget, the dog-headed aluminum bat has another trick, and that is the big bombing.

All dog-headed aluminum bats carry four large aerial bombs weighing 500 kg.

The back of the acid brood demon is specially prepared for hatching demon worms, and its protection ability is very weak.

The dog-headed aluminum bat swooped down at an altitude of several thousand meters, and used acceleration to throw the 500-kilogram aerial bomb in its hand, which could directly penetrate the shell of the acid brood demon, and then go deep into its interior, producing a big explosion.

With the terrifying muffled sound of a lifetime, the stomach of the acid brood demon would suddenly swell, and then the entire body would explode, and the acid in his body would immediately splash in all directions, at least covering a radius of thousands of kilometers.

If ordinary demons were stuck in the face with these acids, it would be a lot of fun.

This is a terrifying existence that can even melt alchemy runes, and the troops below the level of silver will basically be corroded and lose their flesh if they stick a little.

If you cover too much, even the whole demon will melt.

In fact, around all the detonated acid brood demons, there will be a lot of unlucky eggs that will be melted by the acid.

It's equivalent to killing an acid brood demon, and it can also come with a group of small demons, which really makes a lot of money.

After revealing their terrifying fangs, these dog-headed aluminum bats in the sky who were unscrupulously assassinating in the sky quickly attracted the attention of the four high-level demon lords because of the huge casualties they caused.

They naturally gritted their teeth at this, and immediately ordered a counterattack, but unfortunately, the strength of the counterattack was really not much.

First of all, the dog-headed aluminum bat is invisible throughout the whole process, and if you want to fight back, you have to break his stealth ability first.

Secondly, the dog-headed aluminum bats are not fixed, they attack blindly, they are like assassins one by one, pursuing the routine of killing with one blow and leaving after killing, and they do not stay in one place at all.

Then the question is, where to find the dog-headed aluminum bat in such a big battlefield?

In the end, although there are many high-level troops of the Demon Legion, there are not too many demons that can threaten the high-speed flying dog-headed aluminum bats.

Moreover, these high-level demons are also scattered everywhere, and they don't even dare to gather, so how can they pose a threat to the dog-headed aluminum bat?

Of course, the assassination of the dog-headed aluminum bat does not work every time, sometimes they will misjudge the strength of the opponent and go to the trouble of the golden demon with the level below silver, then these unlucky eggs will often be meat buns and beat the dog.

In addition, there are some dog-headed aluminum bats who did not pay attention to the surrounding environment when they were assassinated, and did not look at the high-level demons hiding, and they were also killed by others after revealing their tracks.

However, these unlucky eggs are a minority after all, and the number of dog-headed aluminum bats is also very large, so even if tens of thousands of people die, it doesn't matter at all.

Anyway, in general, it didn't affect the happy assassination operation of the Kobhead Aluminum Bat Army on the front line, and they were still frantically killing the demon's high-level special forces.

In the face of these crazy assassin killers, the four demon high-ranking lords also hated it, but for a while, they really couldn't think of any good way to deal with it.
