The high alertness of the Blood Crow and the timely change of defense strategy by Overseer Shank caused a lot of trouble for the biters.

The "domino" tactics that Zagala had originally planned to carry out were completely untenable.

This tactical plan is based on the multi-layered defense layout of the demon troops, Zagala wants to use the absolute strength of the insect swarm to accumulate offensive advantages from the outermost defense line, and every time he breaks through a defense line, he can drive the rout of the demon army to break through the next defense line in one fell swoop with the power of victory, so that the multi-layered defense line of the demon army is like dominoes, falling down one after another.

It's a pity that the two commanders of the Demon Legion are not fools, so naturally they won't watch Zagara's plan be successfully implemented.

After the first layer of defense collapsed at such a rapid rate, they changed their tactical layout in time, and completely shrunk the layout of the multi-layer defense line that was originally used to consume the swarm and wear down the swarm's spirit, and turned it into a dual-phase defensive front that now relies on each other.

The advantage of this is that you can clench your strength into a fist and face the attack of the swarm with the strongest side, and second, you can shorten the length of the defense line, so that the support can arrive in a more timely and faster manner.

But the downside is obvious, that is, it is easy to be completely surrounded, and all the "territories" that belong to hell must be given up except for the Purgatory Fortress.

Once such a defensive arrangement is made, the demons in the Purgatory Fortress will be prepared to be completely besieged and unable to move.

This is undoubtedly a very difficult decision for the demons who have been on the attacking side before.

However, the Overseer Shank did not hesitate to make this decision, because in its opinion, the biters would never besiege the Purgatory Fortress for a long time, and with the terrifying power they were showing so far, if it were the swarm commander, it would have attacked immediately and won the game in one fell swoop.

It must be said that the Overseer Shank is indeed a rare general under the command of the Lord of Destruction, and although it is not aware of the extreme danger of his master, this does not prevent it from trying to free the last remaining fortress from the swarm.

The Infernal Fortress is the only full-fledged large-scale war fortress in the Second World in the entire Chaos Purgatory, and it is said that its construction was completed by the Lord of Dread himself.

This fortress is home to a large number of small hell portals and a variety of weapons to defend the city.

These include the Hellfire Bed Crossbow, the Hellfire Ripple, and Lava Falls.

The so-called "Lava Falls" refer to a series of lava vents installed on the tall walls of the Infernal Fire in the Purgatory Fortress.

When the enemy begins to siege the city, these lava vents will lead down the portal to the sulfur-smelling lava lakes of Chaos Purgatory, spewing hot lava from the lava lakes down the walls.

It's a vicious but extremely effective weapon for defending a city, somewhat like the Rolling Stones and Boiling Oil in human sieges, but much more powerful than those combined.

And not only that, the head of the Purgatory Fortress and the city are densely covered with all kinds of terrifying traps.

As long as they are not demonic units, they will shoot powerful fire mines into the air to attack the enemy, as long as they are not demonic units.

There are also the "Death Vents" that spew the flames of hell, and the "Shadow Guards" that appear harmless but are actually extremely sinister.

Under normal circumstances, even if the human legions were to one day storm the head of the Purgatory Fortress, these traps would make them have no choice but to retreat.

But when it comes to the swarm, Overseer Shank doesn't dare to make such a decision.

It had seen the landslide and tsunami of the swarm's landslide and infinite numbers from countless previous battles, as well as the endless array of strange methods.

Shank was skeptical that the traps on the city would work wonders for the swarm.

So no matter what, even if it's just for the sake of its own life, it has to do everything in its power to protect the gates of hell - don't think it hasn't thought about using the gates of hell to escape, but the killer guarding the gate is absolutely impossible to let it pass......

That guy is notoriously a killer, and even in a dark and evil place like Chaos Purgatory, few demons are willing to approach it.

Even its owner, Diablo, the Lord of Fear, is not very fond of his right-hand man's extreme character, for he loves to kill almost for no reason, not to create fear, not to devour souls, not to accumulate power.

Pure and pure is to kill for the sake of killing.

And it doesn't like to torture your opponent for fun before killing him, like a demon under the command of the Lord of Torment and the Lord of Pain......

For example, this kind of killing without even a reason to please himself, completely aimless, and searching the entire purgatory, I am afraid that it is the only one......

I don't know what orders this guy got from Diablo lately, and suddenly he started to move his hands on all targets that are close to the gates of hell.

Whoever comes even the slightest closer to the gate guarded by it now will be mercilessly slain by it for no reason!

Shank didn't want to die, that guy was extraordinary, and even if all the demons in the entire Purgatory Fortress were tied together, it wouldn't be enough for him to kill.

So in order to survive, it can only defend the Purgatory Fortress.

Fortunately, the Purgatory Fortress is strong enough, and its chips are quite sufficient, so as long as it can block one or two waves of the swarm, it may still have a chance......

Just as Shank was thinking this, a demonic goblin in charge of the herald suddenly appeared in its command room in a panic, with a very frightened expression on his face.

"Overseer! The enemy is attacking the Blood Crow! ”

The Demon Elf Herald's panicked shouts made Shank very dissatisfied.

Who the hell found this straw bale, the offensive will start sooner or later, is it panicking like this because it wants to be thrown to the front line to "exercise"?

"What are you panicking about?! As a member of the elite legion of the Lord of Destruction, your performance is simply insulting to the majesty of Your Majesty! ”

"But... Lord Overseer, those great monsters have reappeared, and one of them is ......" At this, the herald swallowed, and seemed to ease his fright before stumbling and continuing, "What's more... Bigger! ”

"Huge monster...... "Shanke was stunned for a moment, and then immediately reacted to what the herald was referring to.

It has long been aware of the existence of the Heavy Artillery Governor and the Hive Insect Lord, and has been worrying about how to deal with these behemoths floating in mid-air.

It's no surprise that they will appear in the battle against Hellfortress, but what did the herald just say?

There's also a ... Bigger?

What does that mean?
