In the Basil Hotel, in Zoltan's machine workshop, Wren is concentrating on the operation of the machine, and a small part is gradually taking shape in his hands. ，

Behind him, a metal shelf was placed on top of the table.

The shelf has two conical cylinders made of copper skin, one large and one resembling a long horn, but it is not used to play sound, but rather, it is used to receive sound.

The tail of the conical barrel is connected to a thin needle, and underneath it is a complete set of clockwork wheels.

This is a mechanical phonograph for recording rubber discs!

Ever since Wren got acquainted with Viola, he came into contact with the field of music and remembered the gramophone. He was pretty sure that Ehrenus didn't have a phonograph, but he had something like that, called the Echo Crystal.

The Echo Crystal is an alchemy item, and the main material used to make it is the same as the Sound Meter, which is the Sound Stone.

With the Echo Crystal, it is possible to save the sound and play it repeatedly, but this thing is not very common, especially in the civilian class, and the vast majority of people are unaware of its existence.

Because the Echo Crystal is very expensive, the Echo Stone used to make it is itself very expensive, and after the hands of the alchemist, the price is even higher.

In addition, both the Echo Crystal and the Sound Meter have a drawback, and they must be infused with soul power regularly before they can be used.

In the microphone of the demon slayer team, many transcendent classes without soul power, such as the berserker Hargrove, must ask the caster's teammates to inject soul power every six or seven days, which is like recharging, which is very troublesome.

A piece of Echo Crystal, which costs more than fifty gold guilders, is several years of income for civilians.

All kinds of conditions limit the popularity of echo crystals, and they can only become a luxury for a very small number of people.

It's also rare for people to associate echo crystals with music.

Wren's original idea was to make money, "invent" the gramophone, and record a batch of classic music, which would soon spread throughout the empire, creating a whole new market and making a lot of gold shields.

Later, I had more contact with Viola and knew that Gramophone was more than just making money.

This pair of the god of art and love, the long-haired lady Freya, is definitely a super killer!

Once the gramophone came out, it will quickly become popular in the world, bringing music into thousands of households, and countless people will hear beautiful music that they usually don't have the opportunity to enjoy.

The number of believers determines the strength of the gods, and the long-haired lady may be among the stronger gods with the help of the gramophone!

If Viola can contribute a gramophone to the prayer ceremony, she will definitely get a response from the long-haired lady who will give her a magical spell.

In addition to magic skills, you can also make countless fortunes by making gramophones for sale. ，

The huge wealth obtained with the gramophone is enough to make the Duke of Silver Star pay attention to Viola, and affect the competition for the county of Winterthunder.

Church contributions, family wealth, earldoms.

A gramophone can bring Viola countless benefits and turn her life upside down, and Wren can't think of a better gift.

But it's easier said than done.

Wren has actually been building phonographs since last month, and only after starting to find out that this thing is much more difficult and complicated than the N-machine.

He knew how the phonograph worked, and he remembered most of the mechanical structures.

But if you want to make it exactly right, it will test his memory and hands-on ability too much. The biggest difficulty was not in the gramophone itself, it took him more than half a month to make a semi-finished product, the most difficult thing was to record the sound, and to store the sound on vinyl.

The metal shelves on the table are used to receive sound, and the sound waves cause the needles to vibrate and engrave lines on the plastic plate.

For this seemingly simple plastic disc, Wren put too much effort into it.

In his previous life, vinyl records were made of plastic paint, which had the best sound quality, and was wear-resistant and durable, and it took him a few days to find a similar replacement, barely making a few plastic discs.

And that's just the beginning, as the initial recording is followed by the original recording disc.

It is necessary to process the recording disc through several processes, cross the silver, make molds, clean, and make a metal master, and then use the master disc to press out hundreds of records, so that there is a complete production process and a large number of sales.

At present, Wren is still groping for the production of metal masters, and he doesn't know when he will succeed.

Just asking Zoltan to buy a large number of various materials, one kind of experiment, he has already spent more than 300 gold guilders, and it is expected that he will spend more in the future.

But in order to make a phonograph, it was all worth it.

Just after noon, Wren was having lunch in the lobby of the hotel, and was about to go back to the mechanical workshop to continue his work, when a few vibrations came out of his pocket.

Wren took out the microphone and found that the button in the middle lit up.

He pressed it, and Pollock's voice came out: "Frida, Wren, you guys come here, there is a mission today, and the others are on standby." ”

"Roger. Wren replied.

From Pollock's flat tone, it was clear that it wasn't supposed to be a very urgent task.

Wren wasn't in too much of a hurry, took the Ice Crusher Warhammer and NNN, and got on the bus to the Sheriff's Office.

Half an hour later, he got into a car in the Sheriff's garage, and the captains, Pollock and Frida, both armed, looked more relaxed.

Pollock raised his eyebrows when he saw Wren's warhammer and exclaimed, "Good weapon!"

Frida, who has a cold personality, also looked at it twice.

Wren didn't explain, and waited until the car started before asking, "Captain, what is the mission?"

"An investigative mission. "A wealthy man in the Silver Star District reported to the Public Security Bureau that his neighbor's hostess had not appeared for two months, and suspected that it was a monster. ”

"Understood. Wren nodded.

This kind of report is very common, because of the existence of the blood soul curse, people are very vigilant about the abnormal phenomena around them, they haven't seen a neighbor for a long time, it may be that the other party's curse has occurred, and something has happened in the family.

Of course, it is also possible that the neighbor is just away from home and is not at home.

Usually, this kind of report is a false alarm, or a misunderstanding caused by coincidence, but the demon extermination team does not dare to ignore it, because many monsters and fallen people are discovered in this way.

According to the statistics of the Public Security Bureau, one or two of the ten similar reports were really problematic.

Most of the tasks of the demon slaying team come from reporting, and the last time Ren and his teammates went on a mission for the first time, the fallen person they dealt with was reported by a neighbor.

Pollock continued: "But this mission is a bit special, it is in the Silver Star District, and the male owner of that family is a fifth-level mechanic, his name is Travic, he works in the mechanical union, and it is said that his status is not low. ”

"Level 5 mechanic?" Wren was surprised.

The mechanic is a spellcaster, and the general mid-level and above transcendents are rarely invaded by the Blood Soul Curse, but if they really become degenerates, then the harm is far greater than that of ordinary people.

"Well, so we're going to have to be cautious. Pollock reminded his teammates, and at the same time said: "The Public Security Bureau has sent someone to the mechanical union in the morning to secretly ask, and Travich is behaving normally, and he is still working in the union today." ”

Frida asked aloud, "Is there anything wrong with him?"

"It's not clear. ”

Pollock shook his head, "At least the person sent to respond that it's normal, let's check his house first, see how the hostess is doing, and if there is no vision, then go to the mechanical union." ”

"Okay. Wren nodded yes, this is the normal process of investigation.

Soon after, the car pulled into the Silver Star district and stopped in front of a mansion.

As soon as Wren got out of the car, his heart was slightly cold, he turned on the sound of everything, but he didn't hear any voices or human activity in this house.

The whole house was as silent as death.

To be able to live in a mansion in the Silver Star District, a few housekeepers and servants are usually hired, and even if the master is not at home, it will not be so empty.

He listened to the house next door, and there were a lot of sounds coming from it, which was normal.

"There's really a problem. ”

Wren remained silent, watching the captain Pollock step forward and knock on the door, knocking hard for a few minutes without anyone responding, and the three teammates all had solemn faces.

He knew that this was the result, and immediately kicked the door open.

Bang dang!

There was a loud noise from the iron gate falling, and there was still no movement in the house.

Wren took the Ice Breaker in his hand and stepped through the vestibule, and as soon as he entered the main entrance, he smelled a strong smell of blood, and immediately saw several corpses scattered throughout the hall.

Judging from the clothes of these corpses, they were all servants of this family before their deaths, both men and women, and there was still a little fear in their dim eyes, as if they had been greatly frightened before they died.

They all died of the same cause, being shot through the body or in the head.

Pollock crouched down and dipped his finger in some blood, and confirmed, "They just died, it shouldn't be more than two hours." ”

"You check to see if there are any survivors or whatever. ”

Wren and Frida turned and searched each room.

In fact, Wren knew very well that there were no living people in this house, but he still searched very carefully, and maybe he could find useful clues.

The servants died under the soul, and the murderer clearly pointed at the master Travich.

As an N Mechanic, Soul N is the most commonly used weapon.

If nothing else, the curse of this level 5 mechanic has attacked!

The curse of the transcendent is completely different from ordinary people, and it will not immediately lose its mind, but will change its personality drastically, as if it is a different person, and still have the ability to think, and even disguise itself, lurking, waiting for an opportunity to cause greater damage.

The higher the level, the stronger the transcendent, the more terrifying it will be after becoming a degenerate!

In all likelihood, Travic realized that he had been exposed, so he killed everyone in the family.

The three of Wren searched the entire mansion and found two or three bodies in the other rooms, but nothing else.

That Telavich was cautious and didn't leave a trace.

"Those who die here are servants, and there is no mistress. Pollock said in a deep voice.

This means that the neighbor's report was correct, and the hostess was missing for two months, probably using what reason Telavich used to deceive the servants in the house.

And he himself, the curse has been on for at least two months, maybe even earlier!

The Fallen have been lurking for so long before they are exposed, and there must be some scheme.

Pollock, who had a premonition that something was wrong, led the two of them out of the mansion as quickly as possible, jumped into the car and shouted to the driver, "Go to the mechanical union at once, be quick!"11
