The energy inside the platinum disc is being output strongly, and the scene around the observatory is still the same as the universe. However, from inside the platinum disc, Patrick's familiar aura reappeared, and the phantom of Nogannon appeared in front of Patrick.

This time it was no longer Nogannon, appearing in Patrick's sea of consciousness, but projecting it in the real world.

"Hello! We meet again. "This time the Nogannon is completely different from the previous performance, this time the Nogannon is intelligent, no longer the previous one, purely to instill knowledge in Patrick.

"You're Titano Gannon?" Patrick was a little frightened, the phantom of Nogannon in front of him was too big, fortunately, the environment of the observatory became a vast cosmic space, otherwise a small observatory would not be able to fit Nogannon, and Patrick was like a mosquito next to a human eye in front of Nogannon.

Although it was only a phant, Nogannon's appearance was clearly recognizable, his face was rigid and expressionless, his white gold skin shone with arcane power, he was dressed in a long cloak that covered his head and a tunic with a long beard, and the light of wisdom shone in Nogannon's eyes.

"I am the master of the arcane, the knowledge, the wisdom, and the books, and Almansur appointed me to be in charge of the management of spells and magic in the universe, including of course arcane magic from the warped void, and spells composed of other energies."

Seeing the intelligent Titan projection for the first time, Patrick didn't know what happened to Nogannon finding him, in terms of strength, Patrick's immortal-level strength was completely insufficient in front of the Titan.

"What did you find?"

"Don't be nervous, little one." Nogannon's tone was calm: "You have reached this height, and naturally you can further understand the nature of energy. ”

"I want to tell you that all energy has duality, whether it is the space and time of the zero-level energy, or the arcane, natural, and evil energy of the first-level energy, or the second-level energy, all the energy has a negative and positive side."

"Duality? In other words, no matter what energy, it has nothing to do with good and evil? Is it often just the user who has the problem? ”

"Energy itself has certain properties, such as evil energy that corrupts life, nature promotes the growth of plants, holy light has the effect of regular order, and dark shadows have the ability to annihilate chaos, these are just the most basic properties of energy."

"As a user, the nature of these energies will affect itself, allowing some of the user's consciousness and forms to slowly move closer to the energy."

Patrick nodded, Noganon was right, Malfurion used nature, just look at Malfurion himself, he even had leaves in his hair, and moss was slowly growing on his feet, which was all the change of natural energy to the user himself.

As for the evil energy, needless to say, the fear demon king and the Ereda demon who use the evil energy, even the blood has been changed by the evil energy, turning green, and the whole body always exudes a kind of rancid smell, even if they are close to them, they will be changed by the evil energy, and even the grass under their feet will be corroded by the evil energy.

As for the four elements, needless to say, for example, the fire elemental user fire method, they look very hot, flames appear at their fingertips from time to time, the fire element changes some of their own forms, Lena is a top fire element spellcaster, her hands, hair, from time to time, flames are rising.

Lena is enthusiastic, easily excited, actionable, and willful, but there are also shortcomings, Lena is not careful enough, fiery and irritable, and aggressive, which are all manifestations of the two natures of the fire element.

"It's not enough that the duality of energy is just the positive and negative aspects, there are other states of duality."

"Whether it's elemental or arcane, whether it's divine or incantation, it has a set of realistic physical forms and magical forms, both of which are the basic forms of energy. You can explain energy in physical form only, you can explain energy in magic form only, but you can explain energy in two forms, and the two forms are interdependent, opposite, and merging with each other. ”

"For energy itself, its opposite is itself, which contains not only the symmetry of energy, but also simultaneity, and this interaction is not only manifested concretely in the arcane, but the real material world contains countless examples of duality."

"In the universe, gravity is probably the most common attribute, but it is not alone, but interactive."

"In the vast universe, mixed energies make up this mysterious distorted void, and the energies mixed in the void all have similar dualistic properties, light and shadow coexist, and justice can exist because of evil."

"Existence is inseparable from nothingness, and nothingness is inseparable from being, so this duality will always exist."

"Energy has a certain 'positive and negative duality' characteristics, in the past, the Titans believed that positive energy is positive energy, negative energy is negative energy, the two cannot coexist, can only be regarded as a category, but with the advancement of the study of the void, we abandoned this idea and established a theory of duality."

"I don't know how far you can go in the future, but I hope you can keep yourself forever, not be lost by power, and when you understand the nature of various energies and the principles of various substances, I hope you can keep yourself forever."

……

With a flash of white light, Nogannon's phantom turned into the platinum disk, and the surrounding environment began to change, and the scene slowly changed back to the appearance of the observatory.

Patrick was still reminiscing about some of the concepts explained by Nogannon, and this time Nogannon provided too much theoretical knowledge, and too many things needed to be verified by Patrick one by one

"Duality" Patrick once thought that this concept was far away from him, but he didn't expect that after crossing into the other world, there would be duality.

At the same time, I remember Alexandros's deafening remarks about the Rizeb Crystal: "Can justice exist alone without evil?" Isn't there a shadow on the other side of the Light? ”

"If the answer is no, then is it possible that there must be an equivalent power of Light in this incomparably evil shadow creation?"

Light and shadow will also be the embodiment of duality, and in this way, some of Patrick's previous misunderstandings about energy have been easily solved.

And for the energy will affect the user, Patrick himself has some understanding of this concept, evil energy corrodes life, will make the user's spirit gradually confused, but it is not without the negative state of the evil energy user, such as Illidan, the strongest evil energy user in the world, he can still maintain his sanity.
