Although the mages have the ability to fight against the sky, it is still quite unrealistic to rely solely on magic to shoot down a huge floating city, not to mention that there must be a strong defensive barrier above the floating city, and there are a large number of gargoyles and bone dragons guarding the floating city, and it is very difficult to attack its main body.

Su Chen quickly summoned Mograini and the others to discuss how to retreat safely.

Originally, he wanted to rely on this Daxaron fortress as much as possible to consume some of the power of the undead scourge in order to stop it from capturing Zudak, but because the opponent's air power was too strong, he had to choose to give up.

"Even if the Undead Scourge is supported by the Floating City, we can hold out on to this fortress for a while, and we should be able to further consume a lot of undead troops." Mograini, however, was reluctant to retreat immediately, especially if his side suffered little damage.

"Well, even if the Undead Scourge uses catapults or meat grinders, with the strength of this fortress, it should be able to last for more than half a month before it is breached, and we have a lot of mages who can also manage to destroy the siege equipment of the Undead Scourge." Bridget Abydis analyzed.

"Of course, I believe in everyone's combat effectiveness, but I am worried that the undead scourge will use the plague, we are now trapped in this fortress, although we have a geographical advantage, but once the undead scourge uses the plague virus to drop the plague virus near or inside this fortress, I am afraid that it will cause great damage to our troops." Su Chen sighed.

"Plague...... That's a very troublesome thing indeed. Mograini couldn't help but frown immediately when he heard this.

Everyone has experienced the battle of Lordaeron, and knows the severity of the plague of the Scourge of the Dead, even now there is a large area in Lordaeron's territory called the Plague Land, and there are no creatures that can survive at all.

And more importantly, there is still no good solution to the plague of the undead scourge, and can only rely on a few kind little dryads to slowly purify the earth.

"If the Undead Scourge really uses the plague virus to attack this fortress, then we will have to evacuate, eh...... It is important to have an orderly retreat plan in place to minimize losses. Bridget Abidis said in a deep voice, making battle plans is what she does best.

When the Floating City of the Undead Scourge flew above the fortress of Daxalon, a large number of cavern spiders were parachuted down, and a large number of corpses with plague were dropped.

The entire fortress of Daxalon was soon enveloped in a green plague aura.

"We must get out of here at once and return to the vicinity of the World Tree as planned." Su Chen said in a deep voice, Nao Zu had obviously gone crazy in order to recapture this Daxalon fortress, and the city of Dalaran, which was supposed to move to the Grizzly Bear Hills, was nowhere to be seen.

"Do you want me to help? I might be able to take down that floating city. Chromie said.

"No...... That's too dangerous. Su Chen immediately shook his head and refused, if he wanted to shoot down the huge floating city, he had to get close, the last time the commander of the Dragon Sleep Alliance, Afrashastaz, was seriously injured and fell under the siege of gargoyles, and almost died, he naturally didn't want to let Chromie take the risk at this moment.

The ogre forces that had been the vanguard of the Daxsalon fortress were once again at the vanguard of the breakthrough, and these armored ogre warriors were almost impossible to resist after being blessed with the bloodthirsty magic unleashed by the orc shaman, and easily ran away from the ghouls and skeletons that rushed up to try to intercept them.

The Undead Scourge probably didn't expect the human forces to break through so decisively, and by the time it reacted and mobilized a large number of equally burly abominations and flesh golems, the human army had already rushed out of the fortress of Daxalon.

A large number of paladins surrounded the mages of the High Elves and rushed towards the jungle to the south, and at the back of them were the demon priests of Shivarra, leaving behind terrifying flames of evil energy wherever they passed, and even those flesh and blood golems with strong defense were quickly burned into a pile of char when they walked on the evil flames.

Su Chen also walked behind, and even casually killed several elite ghouls who were fast.

These ghouls were originally intended to serve as cannon fodder in the army of the undead, but over time, some of them have increased in strength and become more and more powerful.

"If all the ghouls and skeletons can continue to evolve, it will be troublesome......" Su Chen sighed secretly, the combat power shown by the Undead Scourge was really getting stronger and stronger, and it also had the potential to further improve.

Due to the influence of the evil flames, the ground forces of the Undead Scourge were rather slow to pursue, but the pursuit of its air forces was extremely fast.

The gargoyles that covered the sky roared through the sky, constantly chasing the troops that broke through, and the bone dragons also lowered their altitude, swooping down with their shattered wing membranes, spewing frost downwards.

Although the human army on the ground retreated in an orderly manner, everyone covered each other, but with the pursuit of a large number of undead troops in the rear, and at the same time there was a threat from the air, it finally began to slowly become chaotic.

Su Chen had already seen that some of his people had fallen under the frost breath of those bone dragons, and there were even two bone dragons who tried to attack him, but they were still on the way to dive before they were beaten down by Shahras's evil magic, and there was not even a trace of ashes left.

"It seems that in order to deal with the undead natural disaster, you must have a certain amount of anti-air ability...... Su Chen sighed secretly, this attack on the fortress of Daxalon was perfect, but in the face of the opponent's powerful air forces, there were still a large number of additional casualties.

However, it is not realistic to train an air cavalry in the short term, and it is difficult to make obsidian statues on a large scale, and it may only be possible to build a huge floating city like the mages of Dalaran, but the resource requirements are too high to support with Lordaeron's current financial situation.

There are more and more paladins who fall under the frost breath of the bone dragon, and many people have to be forced to stop and defend and counterattack, but the effect is not very good, as a flying class, those bone dragons have a natural advantage.

"It's a pity that Princess Hahoran was borrowed by Illidan, otherwise she would have been desperately trying to kill some gargoyles and bone dragons!" Su Chen looked at those paladins who kept falling with a painful heart, but for a moment he was powerless to fight back against those bone dragons and gargoyles.

At this moment, a strange sound suddenly sounded in the southern sky.

"Is it the city of Dalaran that has finally arrived...... No, what are those?! Su Chen originally thought that it would be the belated Dalaran Floating City, but he soon discovered that some strange and familiar flying objects had appeared in the sky.

It's familiar, because the shape of the flying object is too familiar, and it's strange, because it shouldn't be here. (To be continued.) )
