Colin didn't know if this Wald was the same Wald, but given the sparse number of mages and the strong southern character of the name, which was not common in Thunder City, it was not unlikely.

He was a little curious about what kind of person this guy was who was even more fierce than himself - although according to Berkeley, the other party had been awake for more than 10 years when he took the test.

"Lady Finia, may I meet that Wald?"

"This ......"

Phinea hesitated for a moment, then nodded, "Please follow me." ”

Colin soon learned why Phinea was hesitant.

Where does this man in front of him, who can barely tell his age, look like a magician?

Except for the white-washed coat on his body, which vaguely recognizable the appearance of the magic robe, everything else, including the features of his beard, unkempt, and tattered clothes, made him more like a beggar than a magician.

Colin looked at him and the guard at the door, and was a little hesitant to step forward for a while.

At the same time, according to Finia's introductions along the way, he also knows a little about Wald's experience.

It is said that this guy was also a nominal magician of the association, and his future is bright, but I don't know when he started, he became more and more crazy about magic experiments and elemental research, and almost gave up meditation and spell training, which was not a bad thing, but his research was always unique, which was incomprehensible, Berkeley's evaluation of him was "rigorous in logical thinking, too bold in imagination".

Because he often made crazy moves and could not complete the association's commission on time, after several attempts to persuade him to no avail, the association had no choice but to remove him.

With no source of income, Wald could only sell his research everywhere, but his research was either too complex to be realized, or it was a pure illusion, and no one was willing to invest in it, and over time, he made himself look like this.

Colin thought to himself that since this man was able to shine in the written exam, at least he was not a pure madman.

"Ma'am, maybe we can hear what he has to say?"

"Okay." Phinea had already seen Colin's intentions.

……

"Lady Finia, please don't drive me away at once, this time...... This time I can guarantee that my research is valuable, and you can have the magicians of the Chamber of Commerce verify it......"

Perhaps having heard too many of these words, Finia did not bother with Wald's assurance, except that she did not take a few steps back as she had done when the other man pulled out a shoddy stack of planks.

"Mr. Wald......"

"Ma'am! Trust me! ”

Wald interrupted her excitedly, and continued in an almost hoarse voice:

"If you can get the magician who designed the camera to take a look at my research, you'll understand what I mean......"

These words made Colin and Phinea stunned at the same time.

This guy seems to be prepared.

Curious, Colin walked over to see what was written on his board.

Wald gave him a wary look, "Who are you?" What are you going to do? ”

"Don't you want people to validate your research?" Colin said before Phinea could speak.

"You?"

Walder first expressed doubts about the age of the person in front of him, and then saw the gray badge on the other party's chest representing the junior mage, and then retracted slightly, turned to look at Phinea and said, "Ma'am......"

"You can trust this gentleman." Finia said.

Wald then shoved the precious plank towards Colin.

Colin took the top piece, looked at it casually, raised his head and said:

"Research on the longitudinal deflection of sound waves?"

"Yes, yes, yes." Wald saw that the other party understood the content at a glance, and nodded excitedly.

Colin was noncommittal and continued to look down.

However, after looking at it for a long time, his brows furrowed slightly.

What a mess.

He quickly flipped through the rest of the pieces.

The handwriting is clear, the typography is attentive, and the calculation process is precise and rigorous.

But the content is completely unknown.

He raised his head again, looked at the scruffy guy in front of him, and asked, "Mr. Wald, you are also a beginner magician?" ”

"Hmm." Wald lowered his head, as if reluctant to mention it.

"I heard that you did very well in the written test?"

"891 points." Although his voice was not loud, his slightly puffed chest also showed a lot of pride.

Colin didn't ask any further.

After thinking about it, he picked up two planks again.

This time, he endured the discomfort and concentrated on a small part of it.

"It doesn't seem to be that unbearable."

Colin bowed slightly, but quickly sighed again.

This guy is too good at thinking.

However, Colin, who had seen a little bit of the doorway, did not immediately deny everything, and turned to Phinea and asked:

"Ma'am, can you provide a room and prepare some pen and paper?"

"No problem."

……

Reception room.

Wald sat down in his chair with only a small part of his buttocks, looking around a few times in a restrained manner, feeling very uncomfortable in such a clean and tidy environment.

His eyes were full of envy as he looked at the young man who was leaning back on the sofa and writing on the expensive finch paper with the best quills.

"If only I had such a good writing instrument......"

While he was thinking wildly, he saw the young man put down his pen, folded together seven or eight pieces of paper that he had just written in more than twenty minutes, put them on the candle, lit them, and threw them into the fireplace beside him, and let them burn to ashes.

Wald's heart was bleeding.

However, Colin remained unmoved, and sat there silent for nearly ten minutes before turning his head to look at the sloppy man in front of him.

"Mr. Wald, you should know that longitudinal drift is not suitable for cascading sound waves."

"Yes, but if ......"

Before he could finish speaking, Colin raised his hand and interrupted:

"I see what you mean, using a one-way progressive sound wave that has passed through the Steady Wave Pattern to cancel out the interference of the second layer will perfectly fit all the conditions of use of longitudinal floating, right?"

"Yes, yes, yes......" Wald's eyes lit up with excitement.

"However, have you thought about it, not to mention how high the accuracy of this device is, how do you solve the problem of wave frequency jumping, this is the most critical part of your research, but unfortunately I don't see your solution." Colin Road.

"I ...... I can't fix it. Wald said aggrieved and helpless.

"Then I can only say that your research is worthless." Colin said.

"But you can't deny that, other than that, my other calculations and experimental processes are accurate."

"I don't deny it, but what's the point?" Colin said: "It's just a castle in the sky." ”

"Of course it makes sense."

Wald retorted loudly, and then immediately said in a begging voice: "This ...... Sir, if you show my research to the designer of the photograph, he will understand what I mean. ”

This is the second time Wald has stressed this requirement.

And as the designer of the photograph himself, Colin also knows very well why he thinks so.

The problem of frequency jumping is exactly the same as the key difficulty that Schiller Mora encountered when he first conceived the photograph.

In Wald's opinion, if the designers of the camera were able to solve Sir Mora's difficulties, they must also be able to solve the problem of frequency jumping.

However, he did not know that Colin's solution had nothing to do with Schiller Mora, so although he admired Wald's computing power and imagination, he could only say that his research was worthless.

Wald seemed to be afraid that the young man in front of him would not believe it, and immediately bewitched:

"Once my research is established, there will be one more magical engineering item in the world, and I have even come up with a name for it, which is the inspiration given to me by the gramophone, and I call it the gramophone.

"Wouldn't it be interesting that people could store their voices and play them back when they need them?"

Hearing the name "Gramophone", Colin sighed.

It is true that Wald's entire research is in this direction, but the key problems cannot be solved, everything is just empty talk, and if he continues to study in this way, it will not be fruitful in a lifetime.

Colin stood up suddenly, pulled a gold bowl from his jacket pocket, and placed it on the table in front of him.

"I don't want money." Walder looked at the glittering golden lang and swallowed.

"Take it, find a place to take a shower, change your clothes, drink a glass of Fran wine, then find a soft bed and sleep comfortably for the night, and tomorrow morning, come to the Magic Guild for me."

Wald's trembling hand touched the golden lang, and then he came to his senses: "Excuse me, how can I find you?" ”

"Report my name at the reception desk of the association, and someone will show you the way."

"My name is Colin Vane."
