"Adjust the artillery, at three o'clock, and blast those spiders back to their hell for me!"

Muradin shouted to the herald beside him, holding in his left hand a fine war hammer made of black iron, and with a casual wave of it, the warhammer whistled and wrapped in beating thunder and lightning, smashing the heads and bodies of the Viku necromancers trying to climb beneath the fortress.

One minute later, the cannon roared, and the explosion of five shells completely sealed the hole that the spider demon had just dug not far away, and blasted into the sky along with the surrounding undead.

The dwarven prince snorted with satisfaction, he picked up the telescope in his hand, and kept scanning the entire battlefield in Echo Valley, 50 minutes have passed since the raid, and the original undead in Echo Valley have long been swept away by the fierce dwarven warriors, and the earth spirits have also completed the construction of this medium-sized fortress 10 minutes ago, despite the attack of the frost dragon in the sky.

The fortress is located right at the entrance to Echo Valley, and the path to the snowfields behind, there is no doubt about the Earth Spirits' talent for construction, and at least two sides of this fortress are bordered by the Storm Cliff Mountains, which means that the dwarven warriors who are entrenched in it only need to deal with two opponents at the same time.

The secret passage to the Frost Castle is sealed in the fortress, and those who are seriously injured will be sent into the tunnel as quickly as possible.

However, even with the protection of a fortress, the dwarven legions suffered heavy casualties in the 30 minutes that the second wave of undead arrived on the battlefield, and they broke through the protection of Icecrown Glacier as a direct result of the undead being refilled in the Valley of Echoes by the angry Alsace.

Their numbers far exceeded the limits of what the dwarves could handle, but the dwarves withstood this terrifying battle loss ratio with unimaginable tenacity, and were able to strike back sharply, and with the help of the Black Iron Dwarves' constantly operating Black Iron Drills, the dwarven soldiers could appear anywhere on the battlefield without having to kill through the line.

Cunning and vicious, these magic-wielding black iron dwarves ascended to the ground in a drill rig, never fighting the undead in hand-to-hand combat, but spilling a large amount of explosives stored in the drill rig out of the center of the battlefield in a swaying attitude, and even the dwarven shield guards on the city walls would use this extreme method to fight the undead who approached the city walls in the most critical time of the battle line.

Anyway, with the earth spirit, the damage to the fortress will be repaired in the shortest possible time.

The Eagle Knight of the Frost Dwarves and the Griffin Knights of the Hammer Dwarves also took off from the Frost Keep, carrying fire oil and explosives, to attack the undead on the ground from the sky, this method was effective at first, and it was easy to suppress the undead attack, but when the Frost Dragon and a large number of gargoyles entered the battlefield, this support became difficult, but fortunately these undead did not use explosives, otherwise the situation would definitely be worse.

But before the Northern Expedition, the entire civilized world had been fighting with the undead for nearly 5 years, and the method of dealing with the sea of the undead had long been clearly understood by the generals, although the sea of the undead was terrifying, it was not invincible, and it was impossible for Arthas to accurately command every undead, the kind of layer-by-layer distribution of the command system, only needed to kill all the commanders at the bottom, and the stupid, brainless sea of the undead would take the initiative to reveal its defects, and then be separated, and finally completely eliminated.

The dwarven marksmen who relied on the strong walls of the fortress to carry out precise sniping were doing this work all the time.

They were armed with special guns made by master engineers, using special bullets filled with compressed holy water, this expensive bullet was incredibly lethal to the undead, and every low gunshot sounded meant that a high-level undead was found and then destroyed by fire.

After losing 27 front-line commanders in a row, the Sea of the Undead finally became chaotic, and with Arthas not personally intervening in the battle here, the defense of the dwarves and the attack of the undead reached a balance, a very dangerous balance.

As the gate of the fortress opened, the heavily armed dwarven goat knights rushed out of the fortress, led by the dwarven prince Muradin, a brave warrior with a dragon spear made of stainless steel in his hand, followed by heavily armed dwarven cavalry, and finally five steam tanks that had just been equipped by the master engineer, and two teams of griffin knights who had just returned from the battlefield took off again, sailing at a low altitude and rushing out of the fortress with this cavalry.

At this time, he still had to come out to charge, not just to satisfy Muradin's battlefield killing, but also to have more realistic problems in front of him.

Echo Valley is very close to Modresa, one of the four Dark Acropolises, they are in a triangle with Imeheim, erected in the southeast of Icecrown, the second phase of the attack has begun, Arthas must have received the news that Modresa has been attacked, and it is very likely that he will mobilize some of the undead who are besieging the dwarves to stop Modresa.

After all, for the ultimate safety of the Ice Fortress, the fall of Echo Valley was only a trivial accident.

Muradin couldn't allow this to happen, and in the second phase of the battle, Echo Valley was positioned as a decoy for the undead, and he had to make sure that after the raid on Modresa was completed, he wouldn't be blocked by the undead who were outflanking from behind.

In order to continue to attract Arthas's attention, he must continue to increase the threat of his own side, at least let Arthas see the danger after the fall of Echo Valley, or more directly, trap these undead who have entered Echo Valley to death here!

The Dwarven Prince's gaze fell on the far entrance to Echo Valley, a crack between the two peaks.

He's going to blow it up! Leave these undead in this valley forever, and they won't want to go anywhere until Arthas dies!

This looks like a crazy suicide plan, there are at least 4W undead in Echo Valley, and at this time, there are less than 7,000 dwarves left after more than 50 minutes of fierce fighting, once the entrance to Echo Valley is completely sealed, they will have to face a decisive attack from the undead.

That ending would be equivalent to a catastrophe for the dwarven soldiers who were still holding on to the fortress.

But Muradin had to do it! He had to make some sacrifices for the sake of the final victory, for the second stage that was about to end and the third stage that was about to begin.

On the battlefield of Angasa, 110,000 soldiers sacrificed their lives to buy them time for the raid, and now it was the turn of these raiders to make the same sacrifice.

"Cavalry, charge with me and make a way for the steam tanks!"

Muradin's goat's speed had been raised to its highest speed, and at this speed of the charge, he didn't need to wield the dragon lance at all, he only needed to stand it upright in front of him, and the momentum and anger surging around his body were enough to help him do the rest.

Especially in the case of losing the command of the low-level commander, the chaotic thinking of these undead makes them unable to do any effective defense against the charging knights, and on the battlefield in the northern frontier, the knights of the Silver Hand used to deal with these brainless walking corpses in this way, and this tactic has been completely carried forward after entering Northrend.

And under the lead charge of the epic hero-level warriors, there are almost no dwarves who can stop this group of furious dwarves, whether it is the spider demon or the Viku, they are all completely knocked down and crushed under this rushing charge.

The griffin knights flying above the cavalry kept throwing oil and bombs on the ground in front of the knights, clearing the way for them as much as possible, an army with scattered soldiers at the bottom is not enough combat power, this sentence is applied to the current undead is similar, under the guidance of Muradin, this cavalry is almost in the form of recklessly penetrating the military formation, all the way to the outermost part of the Echo Valley.

The more concealed black iron drilling rig was not enough to penetrate the solid rocks and frozen soil at the junction of the mountain range, and more importantly, the continuous use of ten drilling rigs had already put ten drilling rigs in an extremely unstable state, and with so many explosives, it was very likely that they would be destroyed underground along with people and vehicles, so he could only do it all on land.

And any bravery, at the cost of sacrifice.

Even if the entire fortress was helping them to do this great thing, when they arrived at the predetermined place, there were still less than 140 cavalry left, with a loss rate of more than 40%, and even the sturdy steam tanks were only 3 left.

"Prepare to blast! Leave these damn guys here forever!"

Muradin's roar was like a whip, urging the dwarf engineering masters and earth spirits in the steam tank to act quickly, a large number of explosives were "integrated" into the mountain by the earth spirits, what Muradin's needs is only the temporary closure of the Echo Valley mountain pass, not a permanent change of terrain, so it only takes a huge directional blast to get it.

Not even 10 minutes of preparation was needed, but anything was risky, and just as Muradin was standing on the outskirts of Echo Valley, leading his soldiers to rely on steam tanks and griffon knights to resist the backlash of the undead, a powerful, wild, dark aura appeared in vain beyond Echo Valley, and it was rapidly approaching.

With the muffled roar of the dragon, Muradin jerked back, and then saw the massive ice dragon lying on the top of the entire mountain range, observing the entire battlefield with its black eye sockets and blood-red undead fire, and behind it, the number of bone dragons in the hundreds.

The temperature dropped by more than 5° at this moment.

Muradin subconsciously took a step forward, and the activated god descended to make his body even taller, and the ultimate combat stance unique to the copperbearded dwarves had just been completed, and Sindagosa's death breath exploded above the head of this small commando.

34 griffons lost two-thirds in an instant!

The breath of frost and death was like a torrent of ice falling from the sky, and the white light that danced on Sindagosa's new body also made the breath colder and more deadly, like a silver-white scythe swept through the sky full of gunsmoke and darkness, and everything was split in half under the deadly frost.

The Frost Queen's unique skill, Frost Aura!

Everywhere the silver-white light went, whether it was the undead or the warriors, whether it was obedience or resistance, it turned into a cloud of meaningless ice under the extreme low temperature, cold, delicate and terrifying.

More than half of Muradin's expedition was destroyed by this blow, which caused the King of the Hill to explode in anger and pressure, and he picked up the dragon lance at his feet, and under the ultimate power of the gods, the spear shone with beating thunder and rage, like the last shot to pierce the dragon's heart.

"Give me... Die!"

"Bang"

The Frost Witch's head was deflected to the left by the blow, and the spear spread almost down her frost breath, piercing her hard skull, stabbing it into the head of a skeletal dragon flying farther away with an uncompromising scream,

Blood-red anger exploded in the skull, and the unfortunate bone dragon was blown off its head in an instant, smashing from the sky to the ground like a meteor, and the huge body turned into a mess of bones the moment it smashed into the sea of undead on the ground.

"Boom Boom"

The arrival of the bone dragon did not interrupt Muradin's plans, and at the moment when the King of the Hill roared through the death breath with his battle axe and warhammer and rushed towards the Frost Queen, the mountains behind him... Collapsed.

At the same time, there was the scream of Alsace in fright and rage,

"Cunning rats, you broke my gates!!"

"You deserve to die!"
