(The question of the duality of energy may be complex and difficult to understand, but this is important for this book.) Although there will be no children of light and shadow in this book, the idea is used to construct a worldview and a system of power. ）

Not to mention Illidan, the elemental creature of Naru is the best embodiment of duality, where order and chaos coexist, and the light and shadow coexist.

Fire and ice, light and darkness, life and death, these are all opposing attributes, they are both opposites and united.

The theory of energy duality is crucial, at least that's what Patrick thinks.

As a mage, knowledge is wealth, because this is the source of Patrick's power, and any magical creation and spell cannot be separated from knowledge.

This time, Nogannon told himself the results of Titan's countless years of observations of the universe, indicating that Nogannon recognized himself.

As this kind of top-level existence, Patrick can be proud of being appreciated by Nogannon.

Although some details were solved, Patrick became more and more curious about the concept of mental power.

What kind of energy does spiritual power belong to, every thinking life has spiritual power, but the spiritual power of individuals is strong and weak, but even if it is the most ordinary mortal, he can always burst out with a strong spiritual energy at a critical juncture.

This kind of power is different from the explosion of soul energy, the manifestation of spiritual power and the materialization of various energies are completely different, but the energy that bursts out of spiritual power can be manifested in various forms of energy, such as holy light, shadow, elemental, arcane, natural, and evil energy.

This made Patrick unable to understand whether spiritual power can be used directly, as a kind of energy to attack the enemy, or what is the principle of spiritual power, as a mage, it is a necessary skill to get to the bottom of it.

There is one thing that Patrick has already understood, that is, mental power can dominate energy, ordinary mages directly control energy, let magic energy turn into their own means of attack, many refined mages will also add some super magic skills to the spell to improve the effect of the spell.

When Patrick prepares for the super magic spell, he always uses mental power to build a spell model, arcane sequence, and then imports arcane energy into the model, followed by the concretization of the spell to produce the corresponding attack effect.

No matter what kind of spell it is, it is a precise control of energy, and the use of spell models to build spells, although it will consume a lot of mental power and magic power, but this kind of magic is the most stable. Patrick's spells are all high-level spells that interweave several super-magical techniques, and they have the highest requirements for stability.

For a complex large-scale spell model that integrates a variety of super-magic techniques, it is a subtle operation moment of magic power, and then slowly fixes this operation instantaneously and turns it into a spell that can be used normally. And for those spells that have been successfully developed, those experiments and verifications in the early stage are like touching their own limits, and spell accidents will occur if they are not careful.

Therefore, as long as it is a high-level spell, stability and security always come first, if your own spell can't even guarantee your own safety, then what's the difference between this and suicide attack.

At present, Patrick is not able to properly parse mental power, or convert mental power into use-type energy.

Don't think about it so much, now the entire observatory has become a secret room where Patrick places the floating core, and no one will be allowed to enter here, and several guardians will also send iron giants and iron dwarves to guard the observatory around.

The Northlands have come to an end, and the Arcane Covenant's three bases in Northrend, with the exception of full-time researchers and guards, have largely withdrawn to Quel'Thalas.

The three elves of Northrend, Port Maranor, Dal Island, and the Obsidian Sanctuary, will be connected to become the permanent territory of the Kingdom of Quel'Salas, Greythroat Castle has joined the Arcane Convention, and the Bears have also created a route from Grizzly Hill to Port Maranor, ensuring the connection between the Convention and Greythroat Keep.

The future trade will be between Kalimdor, the Eastern Kingdom, and Northrend, and of course, the island of Kurtilas, which is an important source of raw materials for Quel'Thalas.

The construction of Ulduar's outer wall has been completed, and there will be no more Iron Giants and Iron Dwarves in the entire Storm Cliff, and Patrick will directly pack up all the Titan creations here and take them away.

[You're not just taking it away, you're even serving the plates. 】

Regardless of Elune's complaints, of course Patrick can't let it go, the core Titan creation is left here, so naturally all of it will be taken away.

Ulduar slowly floated up and flew south, and Patrick left the observatory and reappeared in front of Kael'thas and the others.

Seeing the High Elf buildings in the corners, Patrick was shocked, could the Erudito be so fast?

Tallonicus seemed to see Patrick's surprise and explained, "Your Excellency, you have been gone for more than ten days, so we have temporarily set up a research room and living house in some inconspicuous places according to your instructions, although it is only a few corners, but the space here is too large for us to use. ”

"Where's Kael'thas ?" Patrick didn't care, after all, Nogannon himself appeared, and Patrick stood in the starry sky, recalling the memory of Nogannon's giving.

"His Royal Highness the Prince has temporarily returned to the kingdom." Tallonikus said respectfully.

"You guys take your time first." Ulduar is really a good place, the buildings on the outside can be sheltered from the wind and rain, and the offensive equipment is paved, and the interior is completely unaffected. "If you have any questions, you can come to me directly, and the other four Guardians will help you understand this place."

The floating city flew to the surface of the sea and flew towards Quel'Salas at a constant speed, the snow outside the city walls was slowly melting, and the speed of the floating city was still relatively fast, just looking at Tallonikus and Passarein, when would they be able to use the Titan's technology for their own use.

……

Kalimdo, Ogrimmar.

Thrall was lying on the bed thinking about what happened during this time, natural disasters continued to occur in various places, tsunamis and earthquakes abounded, although the damage caused was not great, but Sal was keenly aware that the various disasters that appeared in Azeroth this time were definitely not accidents, there must be a mastermind behind the scenes.

The enemy is in the dark, Thrall doesn't know how to deal with it now, ten days ago, Thrall received the news that the Alliance advance team was going to the Noseron Highlands, but the Alliance side now has no information from the Noseron Highlands.

Only with these calamities, the tribe had enough food to deal with, thanks to the advantages of trade with Quel'Thalas, so that the orcs would no longer starve in the barren lands.

But this time, Thrall was a little uneasy, as the chief of the tribe, Thrall should not be uneasy, if even he is not calm, then what will happen to the people below? But whether these earthquakes and tsunamis will erupt violently, no one knows, and Thrall has a premonition of the elemental anger, and what makes the elemental of Azeroth still agitated.

After slaying the Lich King and the Nightmare King, Thrall thought it was all over, but as it stands, it seems that a new evil is about to emerge.
