"There must be a more powerful powerhouse hidden in these undead disasters......," Su Chen thought secretly, he didn't believe that a single Noss could control the tens of thousands of undead besieging the city.

There are many strong people in the Undead Scourge, but if you think about it, there are not many who can take charge on their own, especially since the Lich King should not have formed a Death Knight at this time.

Su Chen was secretly guessing who would be the real leader of this undead army, and there was a sudden commotion among the undead army in front of him.

The eyes of the people on the city wall were immediately drawn to it.

Su Chen also stared at it, and saw that in the ocean of the undead in the distance, it was as if someone had dropped a boulder, and a large area of open space suddenly vacated, and in the center of that clearing, a huge object was flapping its wings and flying into the sky.

"Bone Dragon?!" Su Chen recognized the hideous thing at a glance, and his heart was suddenly shocked, although he had fought with the Undead Scourge several times before, he had never seen the most famous class of this Undead Scourge.

The bone dragon in the distance flew very slowly, and it looked like it might even fall to the ground at any moment.

But it was flying, and the membranes of the bony wings were torn in the wind, leaving a trail of frost in its path.

"These guys resurrected dragons?" There was also a sigh of surprise on the city wall, and everyone's eyes were completely attracted by the huge bone dragon.

In Azeroth, dragons have always been synonymous with strength.

But fortunately, they did not forget that the hideous bone dragon was their enemy.

The nearest mage tower flickered violently with a burst of light, and the crystal at the top of the tower sent a rather powerful ice arrow towards the bone dragon in the distance, a distance that only these magically powered mage towers could attack.

Ice magic has always been the first choice against flying creatures, in addition to its fast attack speed and good lethality, the added freezing effect can often force flying creatures to land, or even fall directly from the sky.

Surprisingly, however, the ice arrow did not have any effect after touching the huge bone dragon.

"Is this bone dragon immune to frost-based magic?!" Many mages were shocked, even the magic emitted by the mage tower could not harm the bone dragon, and the magic they emitted was even more powerless.

As the hideous bone dragon approached, several nearby mage towers immediately began to attack the bone dragon with all their might, but they all switched to other types of spells, most of which were arcane missiles with flexible attacks, and for a while, the brilliant arcane missiles rained down on the bone dragon in the air.

But the bone dragon was undaunted, and began to fly as it spewed a strong breath of frost towards the defensive barrier ahead.

Su Chen couldn't help but be shocked by the powerful combat power of this bone dragon, with his current strength, if he was attacked by several mage towers at the same time, he was afraid that he would soon be wiped out.

"The body of the dragon clan is too strong...... Su Chen thought secretly, a bone dragon is so strong, I don't know how strong it will be in front of it.

He had the heart to let Zhi Brain analyze the strength of this bone dragon, but the distance was too far, and Zhi Brain's current early warning and detection capabilities were still beyond his reach.

After being attacked by several mage towers for more than ten minutes, the bone dragon finally staggered and began to return.

The people on the city wall finally breathed a sigh of relief.

Soon, however, everyone was stunned again...... In the army of the undead in the distance, several bone dragons flew into the sky!

"Where did these undead get the corpses of so many dragons?" Someone was surprised.

Su Chen's face was also gloomy, he naturally knew where these bone dragons came from.

In the desert of Northrend, there is no idea how many such corpses are waiting for the Lich King to be resurrected.

However, it takes a lot of effort to transport these bone dragons from Northrend to Lordaeron, as these huge creatures can't be summoned or created as they can in the game.

As several bone dragons spewed frost breath towards the defensive barrier at the same time, attracting most of the mage towers' attacks, the other undead also took the opportunity to attack.

The sight of the undead pouring in like a tidal wave was so spectacular that even everyone standing on the city wall felt the wall tremble slightly under their feet.

But what was even more frightening was that the lilac defensive barrier began to shake a little like a bubble under the attack of the undead.

Su Chen's face couldn't help but change greatly, could it be that he encountered the general attack of the undead when he climbed the city wall for the first time in these days?

"Luck won't be so bad......" Su Chen instinctively touched the sword box behind him.

"Don't worry, they won't be able to break through this defensive barrier, this is the ...... that has gathered the whole city," a richly dressed archmage calmly began to calm everyone.

However, before the man could finish speaking, the lilac defensive barrier that had been hanging over Dalaran suddenly disappeared.

There was a dead silence on the walls, followed by earth-shattering screams.

"Oh no, the defensive barrier has been breached!"

"Run, the undead are in!"

At this moment, none of the hundreds of mages dared to cast a spell outside the city, and almost all of them used teleportation or flashing skills to flee to the city at the first time.

"......" Su Chen couldn't help but be speechless for a while.

However, to his surprise, a light suddenly lit up beside him, and someone teleported to his side.

As the light dissipated, a pale blue figure appeared beside him.

Gianna...... You can teleport as you like. Su Chen couldn't help but be surprised, he remembered that even if Ilucia became an archmage, she still didn't dare to use the teleportation technique.

You must know that if there is the slightest mistake in the casting of this teleportation spell, the location of the teleportation is likely to be extremely incorrect, and it may even appear in the ground or in the rocks.

"I'm just free to use it in Dalaran City, the city is full of magic, and all kinds of magic coordinates have already been determined." Gianna's face turned slightly red as she spoke, but she still pulled Su Chen and ran towards the city: "The undead have entered the city, and we will organize a counterattack in the city." ”

"Fight back inside the city?" Su Chen couldn't help but be stunned, it was not a good idea to start a street battle with these undead who were not afraid of life and death.

"Well, this is the decision of the council, the people in the city have gathered near Violet Castle in the past few days, and we will use the many mage towers in the city to fight the undead." Gianna said.

"Really...... But I always felt that it was too dangerous. Su Chen frowned, you must know that the last thing that the undead disaster is afraid of is melee, because as the war continues, under the spiritism of those necromancers, there will only be more and more resurrected undead.

Outside Silvermoon City, the High Elves were defeated because of this.
