There is one thing, Shen Yi actually lied - the demon guards are indeed very difficult because of a certain degree of restraint, but this does not mean that it is much easier to defend against the last three rounds of attacks than the demon guards.

In fact, according to the difficulty distribution of the city, forty rounds of attack correspond to the intermediate stage of three difficulties, the advanced stage, and the intermediate and advanced stages of four difficulties.

Since in the eyes of the city, the advanced stage of the low-difficulty area is already equivalent to or close to the low-level stage of the high-difficulty area, so from the twenty-first round, it is to jump two small stages and directly enter the intermediate stage of the four-difficulty area.

In other words, the task they are facing now is actually a task that can only be solved by medium-level adventurers of the fourth difficulty.

Because of this, from the twenty-first round, the difficulty increase has changed significantly.

If Shen Yi and the others still have any advantage over the fourth-difficulty adventurers, it is that they have a large number of people and are quite well prepared, but the pressure they face is still beyond the scope that their own strength can resist.

But Shen Yi can't say all this!

Fighting requires confidence, and fighting without confidence will never lead to victory. If adventurers know that they are facing a task that is no longer what they should be facing, they will be easily satisfied and ready to give up at any time.

But for Shen Yi, who had challenged the Demon God in the second difficulty, this was absolutely unacceptable - there were still three people in the Broken Blade Team who had no bloodline, no matter what, at least one Demon God had to be killed.

Because of this, the next nine rounds of attacks gritted their teeth and defended.

The twenty-second round of attacks soon came.

Void Dragon.

The Void Dragon is a kind of void class between the Void Walker and the Void Elder, and also has the talent of disguised movement, but their strength is stronger, and the most important thing is that their attacks have a strong corrosive effect, which is also harmful to the castle's defenses.

The battle broke out again, and the adventurers once again took up arms to fight the monsters from all directions.

Scenes of bloody fighting were staged again and again, and the only result of the repeated climaxes of the battle was numbness.

Although all kinds of dangerous and ferocious battles appeared one after another in front of Shen Yi, Shen Yi's heart was already unwavering.

He shoots numbly and mechanically, and the fight is more driven by instinct than by rational thinking.

One after another orc warriors fell in the slaughter, torn to pieces, and in the blood, Shen Yi's eyes were red.

Chu Sheng's thunderous roar exploded in his ears, and he scolded: "Shen Yi, is this what you said is easy to deal with?"

Shen Yi smiled: "Anyway, it's indeed easier to deal with than the demon guards, isn't it?"

"Yes, but it's limited, these Void Dragons are too difficult, Lao Tzu hit it with three consecutive blows and saw that he hit the residual blood, that guy disappeared with a disguised move, and then reappeared and was already mixed with a group of Void Dragons. They all look like birds, and I don't even know which one to fight!"

"Then catch which, we have four hours to settle the fight. Shen Yi replied lightly.

"But then we won't have time to rest!"

"You don't really think that we can rest in the next battle, do you? It's good to be able to solve the opponent within the specified time, but it may not be able to solve it in the later specified time, and it is very likely that a backlog will be formed. Then several waves of forces piled up and directly pushed us flat. ”

"Fuck!" Chu Sheng scolded, but he didn't speak anymore, but the meteor hammer danced more and more crazy.

Due to the omnipresent disguised movement of the Void Dragons, it is extremely difficult for adventurers to kill them by focusing on fire. Coupled with the fact that they are an air class, even the group damage skill has limited effect on them.

Fortunately, this kind of movement also restricts the Void Dragon's fire, and the danger is relatively reduced. The battle thus becomes a war of attrition, which is both advantageous and disadvantageous for the adventurer.

The advantage is that adventurers with medicine are always the winners of a war of attrition, and the disadvantage is that long battles allow them to get less time to rest, while drug reserves are more depleted. Even if there is a faction honor to buy all kinds of item potions, it will not be able to make up for such a consumption - the supply of magic immunity potions has been cut off, and even the mana potions are almost bottoming out.

However, none of this is really a problem.

The real trouble is that the city wall defenses have completely entered the brink of collapse under the attack of the Void Dragon.

Due to the Void Dragon's ability to move in disguise, they can attack anywhere in any place, and the castle gate is the Void Dragon's preferred target.

Under the frenzied attack of a large number of Void Dragons, the gate was obviously overwhelmed, like a decimal tree in a storm, already crumbling.

"Quick! Kill these guys! Don't let them break through the gate!" Shen Yi drank a bottle of potion, and the scattered spear shot out, which was already the second bottle of mana potion he had drunk in this round of attack.

The whip shadow dances in the air, the axe light flickers, the iron fist is vertical and horizontal, and the bullet rain is like a tide.

One Void Dragon after another fell in the frenzied attacks of the Broken Blades, but these fierce creatures never stopped attacking the Iron Gate.

When there were only more than a dozen Void Dragons left at the city gate, I only heard a bang!

The castle's iron gates finally collapsed in full view, ending its mission to stop the enemy.

The Burning Legion's gateway to the castle has opened!

Seeing this scene, even Shen Yi's heart was cold. Even though he knew it would happen sooner or later, he kept trying to delay.

It's a pity that he can't drag it out anymore when it comes to this round.

"Shen Yi, the city is broken!" Wei Na also cried out.

Before the city was broken, it was to pay with life!

After the city is broken, it is the harvest of life!

This is an indestructible truth in the world's offensive and defensive wars.

The breach of the city gate means that the adventurers are losing their geographical advantage, and the gap will grow as the enemy strengthens and weakens their own side.

Shen Yi said coldly: "If you break it, it's broken, anyway, it's not that you are not unprepared." Pick up the remnants first, and then prepare for street fighting, and don't forget that we still have two and three layers of defense. ”

His tone was light-hearted, as if it was really as he said it was, no big deal.

Only he himself understands that the second and third layers of defense lines combined are not as important as the first. After all, the former is to keep the enemy out of the country, and the latter is fighting directly at home.

The remnants of the Void Dragon were quickly wiped out by the adventurers, but the battle ended up consuming more than three hours.

After only ten minutes of rest, the twenty-third round of attacks had already appeared.

This time, it's the Nether Troopers.

The Nether Cavalry from the Nine Hells is like the king of the darkness, ruthless, slaughtering, and powerful and incomparably powerful.

If the gates weren't broken, the adventurers would still have a good chance of solving them if they were kept out of the castle, but for now, they had to choose to fight in close combat.

Shen Yi had always hoped that the city gate could be guarded until at least twenty-three rounds, in order to prevent the Nether Cavalry, but unfortunately he couldn't do it after all.

"All adventurers, block the city gates, don't let them in!" Chu Sheng shouted.

"No!" Shen Yi hurriedly shouted: "Don't go to block the city gate, those guys have charging skills, and anyone who is rushed by them will be hurt three times!"

However, he is not a true commander after all, and there are still some adventurers who try to use their strong bodies to block the onslaught of the Nether Cavalry.

They quickly paid dearly for their mistakes.

These cavalrymen, shrouded in black mist, didn't seem to mind the human walls blocking the city gates.

They just silently lined up in columns, and then charged under the fire of the cannonballs.

Whether they charge or die in attack, they remain silent, calm as eternal ice.

Strike!

One of the first Nether cavalry had rushed to the city gates, the hazy black cavalry spear in his hand crashing into the shield of an adventurer.

The adventurer was clearly a defensive fellow, and he was as solid as a rock.

The cavalry spear couldn't move him even a bit, and the adventurer cracked his mouth and smiled: "What a bullshit triple attack, a group of scum with only 5 basic combat power!"

However, the cavalry had turned his horse after striking a spear, and another cavalryman had followed and charged, and another spear stabbed into the shield.

This time, the adventurer's body shook obviously, and the adventurer's eyes who felt the obvious increase in strength showed a hint of surprise, and the third cavalryman had rushed up and hit the shield, and the adventurer's whole body was shocked, as if he had been struck by lightning.

However, this guy is also brave, and he still fights to the death, Shen Yi has already shouted at him: "Hurry back! This is their joint attack skill, and the power can be infinitely stacked!"

What the?

The adventurer was shocked, the fourth Nether Cavalry had already rushed forward, this time the knight's spear actually pierced directly through the adventurer's shield, and in the explosion of fragments, the knight's spear had pierced the adventurer's chest, pierced it with a blow, picked it on the tip of the spear, and then flung it backwards.

The adventurer flew in the air, only to see spears like a forest, poking into the sky.

"No!" the adventurer let out a frightened cry.

Brush Brush Brush!

Countless knights' spears had stabbed at him at the same time.

"Return to ......," the adventurer screamed in despair.

However, even if it is a regression, it actually takes a few seconds for the system to react.

Just as he shouted to return, the knight's spears pierced through his body, pinning him into the air.

The Blood Emblem finally came with a hint:

"E4415 requests a regression...... Sorry, you're dead in battle, you don't qualify for a return, and you can't return. ”

The adventurer's frozen body trembled and squeezed out, "Urban...... Fuck ...... me Mom you!"

His head was tilted and he died, but his eyes were still wide open, and he was obviously dead.

The death of this adventurer finally made everyone realize the horror of this group of cavalry, and the charge and the exertion of group strength are the most powerful reliance, this is the real battlefield main combat class, and it is not afraid of any form of frontal toughness.

Shen Yi had already shouted: "Get out of the city gate! Let them enter the castle and use the street fighting to divide and surround them!"

The Nether Cavalry is a cavalry team, which is suitable for charging and fighting on the plains, and is suitable for charging on a large battlefield and not for fighting separately in a small area.

Since he can't defend himself from the enemy, he has to use the complex terrain inside the castle to fight, which is also one of Shen Yi's backup plans.

However, this is not without cost - if the cavalry is allowed to charge, the outer forts will inevitably be severely damaged, and the various alchemy traps arranged by Shen Yi inside will also be consumed.

Although these traps had been used for consumption since the beginning of their existence, Shen Yi still hoped that they could be used on more advanced targets.

Well, the Nether Cavalry can't be considered a low-level class, at least if it were a decisive battle on the plains, two thousand Nether Cavalry would be able to rush more than fifty adventurers to the scum.

This time, the adventurers finally listened to Shen Yi's words.

They quickly withdrew from the city gates and retreated to the rear or above the walls.

The door of Hyjal Castle was wide open, and a large number of Nether Cavalry hurrahed towards the city, rolling up a black air current, straight into the sky, and drawing a thick black arrow on the topographical map of Hyjal Castle.

After entering the castle, this arrow quickly turned into small black arrows in the face of the crisscrossing road, and continued to charge forward, all the way, but all the soldiers who blocked the way pierced through with their spears.

They have a neat lineup and strict military discipline, and even if they are divided by natural terrain, they still effectively maintain the offensive rhythm of a squad and a squadron, and they are interconnected without being disconnected.

This alone can be classified as an absolute powerhouse on earth, a warrior that any general dreams of.

However, with the entry of the Nether Cavalry, their troubles soon followed.

The alchemy traps that Shen Yi had arranged everywhere began to play a role, with poisonous smoke traps, flap traps, flame traps, cobwebs traps, lightning traps, frost traps, arrow traps, and even various horse traps.

If the previous defensive battle of Hyjal was still taking advantage of the advantage of the thickness of the city's high walls to fight hard, then the street battle that accompanied the fall of the city gate became a war of soft against hard and soft against rigid.

The battle was no longer a huge scene of group bombardment, but was divided into countless small battlefields, which were staged simultaneously in various corners of the castle of Hyjal.

This kind of battle scene is much less imposing than a group duel, but its bloody and cruel level is even more than that.

A troll hunter stood on the wall and threw a spear downward, and at the same time as the battle axe struck the cavalry, a nether cavalry below also threw a knight's spear, piercing the troll hunter's chest, and the troll hunter fell from the city wall with his chest clutched, and was stabbed into a sieve by more than a dozen knight spears as soon as he landed.

A nether cavalryman drove his horse's head, and the undead war horse under his crotch actually ran up the city wall. Just as he was about to reach the top of the city, a huge log was smashed down, and the Nether cavalry was smashed directly from the air, and the successful Minotaur warrior raised his head to the sky and let out a triumphant roar, but then he was pierced and killed by the cavalry spears.

A white bull priest had just come to resurrect him, when a Nether cavalry in the rear suddenly jumped into the air, drew his long sword and cut off the head of the sacrifice, and then a light from the Tower of Destruction struck and directly smashed the cavalry to pieces.

More killings are still carried out between adventurers, Lao Meng's skeleton summoning and Nether Cavalry, adventurers with more powerful agility and strength attributes, once again give full play to their flexible advantages, jumping between the city walls, using the height to attack the Nether Cavalry, and those undead armies made by Lao Meng become the best cannon fodder to absorb damage from the Nether Cavalry.

Traps in Hyjal Castle are everywhere.

The Nether Cavalry's attack was bogged down, quickly turning from unstoppable to inaccessible.

The Nether Cavalry, having lost the advantage of charging and teamwork, was obviously not adapted to this kind of battle, and fell on the way to charge one by one.

However, even if these brave and undaunted creatures were defeated, relying on their high physical strength, high defense and high mobility, they still gave great damage to the castle defenders.

The deadliest of them were the thirty batteries of the outer defensive line, which were badly damaged by the Nether cavalry's assault on the castle.

Although Shen Yi personally led people to protect and resist desperately, a large number of forts were still heavily damaged.

When all the Nether cavalry had been killed, the outer defense line had destroyed eight batteries and severely damaged seven, and with the previous losses, only twelve were left usable.

And the orc warriors themselves have also suffered great damage, although the Nether warriors are not conducive to fighting in a small area, but the strength of their own attributes often makes them able to pull a dive even if they die. Two thousand Nether Cavalry directly caused the death of four hundred warriors and one adventurer, and this was at the cost of Lao Meng's loss of more than half of the undead puppets.

By the time the battle was over, Hyjal's defenses had left just over 3,000 orc soldiers and 49 adventurers, two of whom were killed and three returned.

The twenty-fourth round of attack is the destruction of the guards.

This is another advanced class of the Guardians, and compared to the Demon Guards, they don't have the ability to wartrample that can be a headache for adventurers, but they do have the ability to summon Hellfire.

Each Doom Ward can summon a Hellfire for side combat, in other words, two thousand Doom Wards, each with the Dreadlord's ultimate ultimate.

Although the threat to adventurers is not as great as that of war trampling, it may not be easy to deal with. In particular, Hellfire has a 2-second stun ability when it lands, which is also equivalent to a one-time group stun for each Doom Ward.

This time, Shen Yi finally took out another hole card - mercenary summoning.

Before entering the mission world, Shen Yi hired two heavy shield soldiers.

The two Heavy Shieldmen have 1,800 health, 50 defense, and three active defense skills.

Shen Yi just wanted them to guard the city gate and block the destruction guards out of the gate again.

The impact ability of the Destruction Guard is far inferior to that of the Nether Cavalry, and if you let the heavy shield soldiers block the Nether Cavalry, it will be looking for death, but blocking the Destruction Guard can still support it for a while.

Shen Yidao didn't want to play the tactic of annihilating the enemy outside the country again-the door is gone, how long can he last with two guards?

The point was that he knew that the DOOM Guardians had a habitual trait that if the battle was going on, they would choose to summon Hellfire at the right time.

However, if the battle is fought in a ranged interception mode, assuming that the gates are not broken, the Doom Guardian will unleash hellfire on the city as soon as possible. The reason for this is to use the long-range bombardment of Hellfire to break down the castle, and secondly, to create internal battles and weaken the siege pressure on the periphery.

This design was originally based on the situation of the battlefield and was most suitable for the tactics of destroying the guards, and it was suitable for both long-range and close-range attacks.

But for adventurers, what they are really afraid of is not the hellfire, but those two seconds of vertigo.

Just imagine, once the two sides are close to each other, a group of destruction guards smash the hellfire one after another against a group of adventurers, one stun after another, and the smash alone can smash everyone to death.

Therefore, the first thing Shen Yi wanted to do was to use the tight defense of the heavy shield soldiers to lure the destruction guards to use hellfire en masse.

When Hellfire falls on the castle, it will also stun everyone, but it does not have the stun that destroys the guard's attack, so there is no threat to speak of. This, combined with the fact that the Hellfire is too far away to concentrate its attack, greatly reduces the threat of the initial attack.

Of course, the consequence of this is that the city wall will be terribly destroyed again, but Shen Yi is basically ready to give up the outer defense line at this time, so it doesn't matter.

The battle really went in the direction that Shen Yi had expected.

Due to the joint defense of the two heavy shield soldiers and the fat man, who are particularly good at defense, the Doom Guardians began to use Hellfire against the castle.

Huge flaming meteorites fell wildly in the sky, smashing into the city, smashing into the sky and smashing into the sky. Some of the hapless soldiers were smashed straight into the air by the hellfire that fell from the sky, but many more were just smashed into the air.

Two thousand hellfires fell into the city, and a new frenzied battle began.

The Hellfire siege without the support of the destruction guards is, to put it bluntly, a repeat of the eighteenth round of attacks.

For an attack of this difficulty, the combination of adventurers and orcs can still be handled relatively easily.

As for the periphery, Lao Meng and Shen Yi teamed up again to stage a good show of smoke bombs and frost sorrow. However, the life of the Destruction Guardian is much higher than that of the Demon Guard, and the effect of Lao Meng's Immortal Youth Spring Water has been lost, so he has to retreat after only killing a fifth.

Fortunately, when the two heavy shield soldiers were finally killed, and the fat man and the others retreated, the battle against Hellfire in the castle had also come to an end.

More and more reinforcements reappeared at the top of the city, fighting against the influx of destruction guards, and finally withstood this ferocious and powerful attack.

Of course, the defenders also paid a huge price for this - the outer line of defense was almost completely destroyed, and there were many gaps in the city wall, like a sieve, which could not be blocked no matter how it was blocked.

None of the outer forts survived, and it can be said that the entire outer defense line was completely destroyed and completely reduced to ruins.

In this way, it was carried out on the basis of Shen Yi's prediction of each round of offensive arms and the timely formulation of targeted strategies.

It is conceivable that if there is no internal information, perhaps the adventurers will come to this point, and it will be the end.

However, for Shen Yi, he was still not satisfied.

Because the current progress is still a full six rounds away from the progress he wants!

But fortunately, at least in the next round, he doesn't have to worry about whether he can get past it.

"In the twenty-fifth round of attack, it was Arida Wizard who cooperated with three hero-level demon kings. The three heroes and demon kings are just that, Hong Lang solves one, Gentle solves one, and Chu Sheng solves one. The Eredar Wizards are quite troublesome, they are a powerful mage-type class, they are true group attack experts, but most importantly, they have a psychic attack skill that is simply unstoppable...... Luckily, when you're prepared, sometimes the sharpest attack turns into the weakest attack."

At this moment, Shen Yi said word by word: "Luo Hao, Yi Yu, it depends on the two of you to deal with Arida Wizard." ”

The fat man smiled: "You just see." ”

PS: No matter what, I'm working hard and trying to write every chapter well.

If anyone is not satisfied, I can only say that it is a lack of ability, and it has nothing to do with attitude.
