"Isn't there those Titan Guardians stationed in Ulduar, how could something happen?" Crassus asked, confused.

Even in the eyes of the dragons, those Titan Guardians are still extremely powerful.

"Those Titan Guardians had internal conflicts many years ago, and Malygos and I went to help Tyr fight some of the giants who were chasing them, and the giants of the different factions in the Storm Mountains are still fighting, and now thousands of years later, no one knows what has become of Ulduar's interior......" The Red Dragon Queen sighed with some concern.

"So it's likely that the King of the Blue Dragons discovered something after getting Tyr's arm, so he was willing to immediately abandon the plan he had been insisting on cleaning up the net, and instead went to Ulduar to check it out himself?" Chromie guessed.

This also made Su Chen sigh again that she had guessed everything, but even Chromie didn't expect him to play a key role in it, after all, Ulduar's affairs have always been extremely secret, and humans have rarely even been involved in the Northrend Continent before, let alone know any information about Ulduar.

"I guess that's what you guessed, Chromie...... No, I'll have to go to Ulduar too, and Malygos won't give up control of the Eternal Eye unless he is in danger. The Red Dragon Queen Alexstasa said quite resolutely.

Su Chen couldn't help but be taken aback when he heard this, a blue dragon king had already disappeared, if the red dragon queen was also lost in Ulduar, then the dragon clan was afraid that it would face unprecedented chaos, and it would also make Ulduar highly concerned by the world.

"Your Majesty, please don't get into danger until the situation is clear, and the mission of exploring Ulduar can be left to someone else." Su Chen hurriedly said.

Now that the Blue Dragon King has disappeared in Ulduar, it is impossible to completely stop the other people's curiosity about Ulduar, and the only thing he can do now is to delay time, even if it can drag on for a few years, it will give him some more certainty.

Since he came to this world, he has been in battle almost all the time, without the slightest rest, but although his strength has grown very quickly, and he can even fight with dragons, especially the blue dragon that is only good at magic attacks, but as long as he thinks about the enemies he needs to face, he still can't help but feel hopeless.

Undead Scourge, Elemental Lord, Deathwing, Elder Gods, Burning Legion...... These are far from what he can match at the moment.

The other dragon clans were obviously also unwilling to let the Red Dragon Queen personally take risks, and immediately supported Su Chen's suggestion.

"Your Majesty, what His Highness Arthas said makes sense, at present we do not know the specific situation of the disappearance of the Blue Dragon King, Your Majesty really can't go into danger at will, and the task of exploring Ulduar will be left to me." Crassus volunteered.

The Red Dragon Queen hesitated for a moment, but finally nodded, she also knew that her safety was currently related to the success or failure of the entire Dragon Sleep Alliance, and she also trusted Crassus's ability very much.

Su Chen finally breathed a sigh of relief when he heard this, although Crassus's status was also extremely important, it was better to hang up a Crassus than to hang up the Red Dragon Queen.

It's just that after the disappearance of the Blue Dragon King, even if the Red Dragon Queen has returned to the Dragon Sleep Temple, it is difficult for the Dragon Sleep Alliance to immediately launch an attack on the Undead Scourge.

"It seems that the battle against the Undead Scourge is really going to turn into a protracted war......" Su Chen sighed, this would be a huge test for the human kingdom.

The Northern Expedition of the Undead Disaster is exciting to say, but behind the northward march of the army is a huge logistical burden, even if the dragons currently bear a large part, but once they fall into a protracted war in the future, the logistics problem will definitely have to be solved by the humans themselves.

At present, we can only hope that the reclamation operation of the Scarlet Crusade led by Mograine in the Grizzly Hills can go smoothly, after all, the current Grizzly Hills do not have any other powerful forces except for those Night Elves who are bent on healing the World Tree, and Mograine and the others are easy to gain a foothold, once they can establish a base and control the most fertile river valley in the Grizzly Bear Hills, they will have the opportunity to solve the logistics problems of the Northern Expedition on the spot.

To Su Chen's surprise, Crassus actually came to chat with him before going to Ulduar.

"Thank you very much Your Highness Arthas for quickly going north to support our five-colored dragon clan this time, if it weren't for the arrival of His Highness, I'm afraid that the Dragon Sleep Temple would probably have been captured by the Undead Catastrophe." Crassus said gratefully.

"Your Excellency is too polite, we were originally allies, we just defeated those zergs together in Angela, and now that the dragon clan is in trouble, we should naturally help, not to mention that the undead disaster is also our human enemy, even if there is no invitation from the dragon clan, we will take the initiative to deal with the undead disaster." Su Chen said modestly, but at the same time, he was a little worried in his heart, this Crassus had been changing into a high elf for a long time to stay in Dalaran, and he had long been accustomed to the deceit of humans, and he was an alternative among the dragons.

Now he took the initiative to run to thank him repeatedly, which was really inconsistent with the arrogant habits of the dragon clan, and it also made Su Chen doubt his true purpose.

"Originally, according to the established plan, it should now be the dragon clan and the human army to work together to annihilate those undead, but unfortunately the blue dragon king suddenly disappeared, which is a very huge blow to the five-colored dragon clan, and it also makes the dragon clan unable to do anything else at all, and the plan to exterminate the undead natural disaster may be further delayed, but although it is difficult for us to organize a large army to go to the icecrown glacier to exterminate those undead, we still have to try to clean up the undead in the dragon bone wilderness." Crassus said apologetically.

"Clearing the Dragonbone Wilderness of the undead? Haven't all those undead scourges already receded, even the tomb of Galakron, they have already given up. Su Chen asked with some surprise.

Ever since the main force of the Dragon Sleep Coalition returned from the Demon Hub, those undead have been running faster than anyone else!

Crassus immediately shook his head and sighed: "No, there is still a place where there are a large number of undead, that is, the Black Dragon Holy Land, and those undead are still unwilling to give up the remaining dragon bones in the Black Dragon Holy Land. ”

When Su Chen heard this, he couldn't help but think of the ambassador of the Black Dragon Legion, Naris, and he didn't know where the Black Dragon Ambassador had gone.

However, Crassus came to mention this matter to him, and he didn't want the human troops to help recover the Black Dragon Holy Land, if that was the case, it would be too bad...... (To be continued.) )
