"Sonic warfare? It's really hard to do. ”

The Qin people, who continued to control the quicksand to rotate on the surface of his and Alyssa's bodies, forming a hazy sand cover, pushed away the wall in front of him.

"Maggots are maggots, and sure enough, they still use the means of digging the ground."

The venomous-tongued Alyssa glanced at the sand circulating around her and walked out behind the Qin people.

"Maggots don't dig into the ground, and it seems you lack some common sense, Miss Corpse."

The Qin people, who had already been immune to Alyssa's poisonous tongue, sneered at each other without any change in their expressions.

"That's the earthworm."

"There are no earthworms in the desert."

"That's a sandworm."

"I'm sorry, it's a beach, not a desert."

While arguing with Alyssa, Qin Ren advanced in the orphanage, and then, he said loudly:

"Miss corpse, don't move too much, don't stick your hands out of the sand."

"You're useless at all......"

"It seems that the Renaissance corpse lady really lacks common sense."

I Qin Ren turned his head to look at her, and then popularized his knowledge to this corpse puppet lady in the 19th century overhead world:

"Dwork's automaton series 'Hellhound' is equipped with a circuit of 'speaker operation', and the means of attack and perception are through sound waves."

"It's easy to defend against such a means of perception."

"First, sound wave absorption, the essence of sound waves is vibration, as long as the energy that can be released by the other party is consumed, that is, absorbed, so that it does not return, you can achieve the effect of defending against sound wave detection."

"Second, the reflective surface is deflected, similar to the water flow magic I used to defend against you, changing the surface structure of the gravel, so that the returning sound wave is deflected in the direction and does not return to the sound source, so that the detector cannot receive the returning sound wave."

"Third, inverted neutralization, by emitting inverted sound waves, neutralize the other party's detection sound waves, which is the so-called active noise reduction, oh, sorry, I guess you don't know what active noise cancellation is."

The technique of using sand to feel vibrations and pronounce sounds as a sound source,He developed it in the Forbidden World,When he was in the school city.。

Although the original purpose was to make his voice appear high, it was enough to bring its own echo.

As for Qin Ren's words, Alyssa surprisingly did not immediately refute them, but asked:

"Can you do such a delicate operation?"

"Of course."

Compared to the school city,This world is completely a world of low science and low magic.,If it weren't for his own lack of magic,,He would be able to do easier means.。

For the Qin people who possessed the fragments of the desert power, he could complete these methods, but the operation was slightly more elaborate than usual.

Moreover, he can also do another means -

Directional conduction.

The incoming sound wave is directed to another location, and even through directional deflection, the detector perceives a non-existent source of reflection to mislead.

Immediately, he said something ambiguous to Alyssa:

"It seems that you didn't remember what I said before, I've died many times."

Qin Ren's words made Alyssa stagnate:

"What do you mean—"

However, the Qin people did not mean to stop and think about it:

"It's okay to understand however you want, but don't stand still."

......

At the same time, among the houses of stone casting.

The two of them and a dog stared at each other.

The old black dog stared at the device beside it, the device tied around its neck, connected by pale chains to iron pillars.

"This device is able to forcibly suck out my mana, forming chains that bind me here."

"Understood." Akabane Raijin took out the tools he was carrying with him and disassembled the device on the iron pillar, "Speaking of which, your name is-"

Immediately, Akabane Raijin heard the guard in front of him, or the prisoner, and heard the old black dog who had made a verbal agreement with him, this forbidden puppet, and said his name:

"My name is, Yellow Spring."

"Add your magic to me, too."

"Okay~" Xiao Zi smiled and touched it.

......

"This is ......"

Feeling the chill rushing towards her, the chill of ice and snow magic, Alyssa's eyes narrowed.

"Something you should be familiar with."

The Qin people, who had already seen the structure clearly through the solar disk, took a step forward.

Alyssa entered.

In front of the eye, there are large cylindrical glass jars that look like culture tanks.

In the unfrozen liquid, there floated a corpse with hands and feet, a torso, and a head.

It's not the automata's hands and feet, it's ...... Flesh and blood.

And judging by the size, it's clear that it's a child's.

"Forbidden dolls."

Alyssa's eyes narrowed as well.

As a forbidden puppet, the moment she saw this, she understood the situation.

"It seems that DWork and others are not satisfied with using dogs as taboo dolls, and have begun to use humans as materials."

His gaze swept over one glass trough after another, and Qin Ren said to Alyssa:

"What are these, in your opinion?"

"Materials after the experiment."

Alyssa glanced at it and made a judgment based on the traces left on some of the flesh parts.

"Post-experiment materials?" Qin Ren touched his chin, "Speaking of which, you said before that Frey and Loki's dolls have had their dolls get out of control, right?" ”

"That's right." Alyssa responded, without any reservations about Felix's affairs, "Felix's speculation is that as brother and sister, they have similar flaws......"

"Nope."

Qin Ren interrupted her:

"It's not so much a genetic defect as a technical defect as an artifact."

Through the solar disk, his gaze was fixed on another building, in a room.

At the door of that room, Akabane Raijine, the little girl with the puppet, and the big black dog were all standing in front of the door.

Judging by the guards at the door, they are all invisible.

However, it was not them that the Qin people cared about.

It's the people inside.

Inside the room, there are little boys and girls who are less than ten years old, and they are .....

Their eyes were all red, and their hair was white as pearls.

The limbs of the children in this room are the remains of the "orphans" who have been dismembered and reused after they have died.

Turning his gaze, Qin Ren looked at another room again.

In the middle of the room, there is a pile of materials.

In the distance, the Qin people controlled the gravel and turned the paper with the words written, and with the help of the line of sight of the solar disk, they confirmed the information.

In a short time, he had already looked through most of them, and he also knew about the facility—

This orphanage is a breeding tank for laboratory animals.

Elsewhere, children with magical talents collected from all over the world were experimented with "Children of the Contract", implanting Eve's heart, the heart of a Karakuri puppet, into them.

Alternative "forbidden dolls".

If these children die because they can't bear the skill of the heart, they are dismembered to study the specific cause and design a better plan through research.

"It's ......"

Qin Ren just shook his head.

The so-called freedom, if left unchecked, will inevitably become a tool and an excuse for the strong to exploit the weak.

He turned his head to look at Alyssa, "You say, the watchdogs of the Wizards Guild, would they be interested in this news?" ”

Alyssa looked at him and didn't respond.

"However, you have to act quickly, otherwise if you are sold by the forces behind Mr. Last, you won't be able to sell it for a good price."

"However, we have to pack up the materials first, maybe there are divine ingenuity materials in them."
