After a while, the four mages moved to the small hall of sunshine on the second floor of the castle.

The decoration of the small hall is also extravagant, because the window is sunny, and the afternoon sun shines in just right, dispelling the chill of early spring in the north.

Entering the small hall, as soon as the door is closed, the hustle and bustle of the hall on the first floor is completely cut off.

After sitting down again, Rosen smiled and said, "Two elders, let me ask you a question first. ”

After getting a nod of agreement from the other party, Rosen continued: "Everyone says that there are strong and weak flames, so what is the external standard for judging strength and weakness? ”

When Fuller heard this, he clapped his hands and said, "This question has a level, and it goes straight to the essence. ”

Master Bilgu pondered for a moment and said, "It seems to me that metal can be used to make an evaluation. ”

"For example, the firewood of ordinary firewood can only burn ordinary mortal iron, but it is difficult to burn, obviously it is not strong enough. However, the black stone mined underground can easily melt the iron, and it is naturally stronger. ”

"Correspondingly, there are fires that can melt copper, flames that melt mythril, flames that melt myth gold, and even flames that can melt the inextinguishable Aojin."

This judgment can be considered a standard, but it is too crude.

"What does Master Alan think?"

The young mage Alan thought for a moment and said, "I think that although my uncle's method is very intuitive, it still has obvious shortcomings. ”

"For example, the Breath of Flame I unleashed can melt copper, but not iron. If there is another flame mage, it happens to be able to do this. So how do we judge the strength of both of us? ”

Bilgu spread his hands.

"Then you can only use the temperature method from the east, use the immortal Aojin as a ruler, the temperature is high, the ruler will become longer, and how much longer it will be, it will be as much as the temperature."

Rosen asked again: "Then what if the temperature is higher than the Immortal Aojin, and the Immortal Ao is financialized, even the temperature at which the most difficult to melt permafrost krypton gold is melted?" ”

All three mages shook their heads.

Mage Fuller said, "To be honest, I haven't seen a flame that can financialize permafrost krypton, but the power of a mage comes from imagination, and probably such a flame only exists in imagination." ”

Bilgu immediately corrected unceremoniously.

"Old man, imagination must also rely on reality, if there is no real world as a backing, imagination is a flying dandelion, looking beautiful, in fact, it has no effect."

After speaking, he said: "When I was younger, I also imagined that my mana was a flame that could melt everything, but in the end, the mana growth rate was far less than that of directly meditating on the sun. ”

Mage Alan looked at Rosen, "So, Mage Rosen, it's time to reveal your answer, right?" ”

As soon as he said this, the two old mages also looked at Rosen.

Lawson smiled and said, "I'll show you a little trick first." ”

He first picked up the wine bottle, poured most of the crystal clear moonshine into the quilt, and then looked at Bilgu.

"Can I unleash a little light mirror trick here?"

It is the etiquette of a mage to get the master's permission before casting a spell in someone else's house.

"Of course."

Lawson walked out to the window in the sunlight, raised his glass, and let the sunlight pass through the transparent wine.

Just when the three mages didn't know why, he performed a small light mirror technique in the drink.

I saw that the sunlight passed through the wine, shone on the light mirror, and was reflected on the wall by the light mirror.

When Alan looked at the light spots on the wall, he couldn't help but exclaim: "Ah~ It turned out to be a rainbow!" ”

Bilgu was also startled, and then shocked, suddenly thought of something, and fell silent.

Obviously, this little experiment inspired him.

Mage Fuller took a sip of moonshine, smiled and didn't speak, waiting for Lawson to reveal the final mystery.

Rosen went on to explain.

"Look, a golden ray of sunlight, after the decomposition of water and mirrors, reveals a seven-colored band of light, and this is not because of my magic interference."

"Because nature has already revealed the secrets of the sun through the beautiful rainbow after the rain."

Bilgu took a sip of his drink: "Interesting~ really interesting~ Young man, continue." ”

Rosen continued.

"Mage Bilgu, Mage Alan, when they released the Flame Missile, they must have had an experience."

"That's that the color was dark red at the beginning. As the power gradually increases, the color will gradually move towards purple, and even to the realm of the master, it will become the violet flame that everyone hears and changes! ”

"This illustrates the fact that the higher the temperature of the flame, the closer its color is to purple."

"In other words, the rainbow is a thermometer given by nature."

'Smack! Syllable! Syllable! ’

The small hall resounded with Bilegu's applause, and his eyes lit up: "Ah~ What a profound insight!" ”

He didn't expect to get the true knowledge from his juniors, because meditation was very mysterious.

Rosen's high mana strength may be because of his true knowledge, but it is more likely that he is talented.

But now it seems that he was wrong, this kid really has good things!

On the side, Alan also reacted a little: "So, what Master Lawson is meditating on is a dark purple sun?" ”

Lawson shook his head: "No. ”

"Ah~ What's that?"

"What I meditate on is the sun in the sky. It's just that my deep understanding of the sun has given me a deeper understanding of the sun, so I have a stronger resonance when I meditate. ”

Bilgu nodded slowly, and praised from the bottom of his heart: "Master Lawson can say this, which means that he has a deep understanding of the essence of visualization. ”

He looked at his nephew and said solemnly, "Remember, the essence of visualization is the power resonance with the object of visualization. If the visualizer does not exist, the resonance does not exist, and the mana cannot be discussed. ”

"In any case, the sun is still the grandest and most magnificent star in the sky. The only right thing for us to do as sun mages is to learn as much as we can about the sun in order to increase the intensity of the resonance! ”

Alan immediately stood up and saluted, "Thank you uncle for your teaching, and thank Master Rosen for generously sharing his wisdom." ”

Rosen smiled: "Don't worry, two mages, I haven't finished talking yet." ”

If you only tell the secret of visible light, then anyone with a little eye can find it, but it is just a daily ignorance, and it cannot really shock Bilgo.

And only when he is shocked can he be truly valued by the big guy.

How shocking?

That is to say the knowledge that he never thought of!

Lawson was still standing in the sunlight, maintaining the rainbow spots on the wall, and said at the same time, "Fellow mages, do you think that beyond the red and purple light, there is nothingness? ”

"Huh?!"

Bilgu was shocked, and his eyes widened.

Because he never thought about it, not even in a dream.

Rosen's words hit his cognitive blind spot directly!

Rosen looked at Alan, "Master Alan, please come here, put your hand in the darkness under the red light spot, and tell me how you feel." ”

Alan curiously complied.

After a while, a look of surprise appeared on his face: "Uncle, it's warm here, it's warmer than other places. ”

At this time, Bilgu couldn't sit still, so he got up to verify.

Sure enough, the same fact was discovered.

Moon Mage Fuller was also curious to try, he tried not only the infrared region, but also the ultraviolet region, and then he felt strange.

"The infrared zone is warmer, and the UV zone is basically the same as that of a normal wall. Shouldn't the purple flames be more powerful? ”

Bilgu immediately went to try it, and sure enough, he made the same discovery.

At this depth, he couldn't figure it out at all, and he had no clue at all, so he could only look at Rosen, a junior, with a plea for help.

And this kind of gaze, he hasn't appeared in at least thirty years.

Under the gaze of the three mages, Rosen gave his final conclusion.

"The warmth of the infrared zone tells us that in addition to the light that the eye can see, there is also light that the eye cannot see."

"And I was once confused by the perverse phenomenon of red and purple light, but then, I thought of a possibility."

He looked at the three mages: "I think the essence is resonance. ”

"Resonance?" Bilgu couldn't figure it out.

The other two mages couldn't figure it out either.

Rosen went on to explain.

"Soul resonance, can allow mages to gain mana. But this phenomenon of resonance does not exist only between souls. ”

"There is also a mutual resonance between inanimate matter."

"For example, if a vibrating sword is close to another stationary sword, even if the two sides are not in contact, it may cause the latter to vibrate."

This kind of phenomenon is very common, and all three mages have observed it, and they all nod their heads in approval at this time.

Rosen continued.

"So, I thought of a possibility."

"Red light may not be as hot as violet light, but it resonates more with objects. So much so that objects, such as our hands, gain more 'mana', so that we feel warmer. ”

Finally, Rosen added.

"Of course, this is all my guess. However, when I added this part of my thoughts to my meditation, there was a fairly significant increase in the efficiency of my meditation. ”

Meditation is a very mysterious thing, and the effects of the same knowledge vary from person to person.

Rosen can only be sure that supplementing knowledge will improve efficiency, but how much it will improve is a blessing for itself.

But that's enough.

Hearing these words in the ears of the three mages, they were as deafening as spring thunder, and the three of them were stunned.

For a long time, Bilgou raised his finger and pointed at Rosen, his fingers trembling uncontrollably.

"This, this, this."

He didn't know what words to use to describe Rosen.

He has been stargazing for more than 30 years, trying in vain to spy on the mysteries of the sun, but he did not expect that true knowledge is hidden in the sunlight that can be seen every day!

For a long time, he let out a long sigh, and his wrinkled face, like Fuller, showed undisguised loneliness.

"I've always prided myself on having eyes looking up at the stars, and I've always been proud of them."

"And now it seems that in fact, my stargazing eyes are not fundamentally different from the eyes of ordinary people, far less than Rosen's eyes of insight into the law."

"Hey~~"
