Danmaku, my skills refresh weekly.

"How long has it taken? We're already on the 37th floor?"

“About 40 minutes,” Charles shrugged. “Sometimes, breaking the rules and thinking differently makes everything much easier.”

In the future, Reussman attempted to dig a vertical shaft directly down from the very center of the underground city, supposedly to facilitate access to each floor, but the risks were simply too great.

Not only does it require a huge amount of the hardest metal, but it also requires constant vigilance against monsters taking over the shaft.

But if we look at it another way, the travel time between the upper and middle levels is not much at all, so building a vertical shaft for this purpose is really unnecessary.

For example, the Dark Faction can dig a hole directly outside the city and outside the underground city, creating a hole that leads directly to the depths of the labyrinth. This not only reduces the impact on the underground city, but also prevents monsters from hatching if the area is far from the labyrinth.

"It saves three days, but the round trip takes six days. This passage can accelerate the adventurer's growth efficiency by more than six times."

Alfia's feelings were somewhat complicated.

The tunnel not only saved travel time but also conserved supplies. She also saw scattered groups of Ikeros Familia escorting ultra-hard metals and various monster materials mined from the dungeon back through the tunnel.

Not only people, but also materials and magic stones can be sent back to the ground by songbirds, increasing the speed of making money and stockpiling materials by dozens of times.

The city guilds, as the managers, only care about the stability of Orario, not its progress. They block information and hinder the adventurers' development.

Charles said helplessly, "At present, only the secret factions can enjoy this kind of convenience. If the city wants to do something similar, it will be more likely to drag things out and negotiate with all parties, and ultimately nothing will come of it."

“I have this urge to go back and tear down the Tower of Babel right now,” Alfia said, clenching her fists.

“Hey… it’s not the same thing.” Charles rolled his eyes: “Without Uranus’s prayer, the monsters from the deep layers can easily come up, and we won’t need to go all the way down to find monsters to grind.”

“That’s why I wanted to tear down the Tower of Babel,” Alfia said with regret.

"In an age where everyone is blessed with good fortune, if monsters were to emerge from the ground, it would likely be the monsters, not humans, that would be attacked. Under such intense pressure, even those adventurous people who live a life of leisure would be forced to take up arms and fight, thus achieving personal growth. High-level adventurers would no longer need to waste time searching for suitable monsters in the lower or deeper levels to hone their skills."

"Uranus's prayers, while ensuring the stability of the world, also limited the possibilities of humanity. So, even after a thousand years, we still cannot do what the heroes of a thousand years ago did."

"This is undoubtedly a step backward for the times."

It was rare for Charles to hear Alfia say so much, and he couldn't help but nod to himself.

"In conclusion, that's correct. Although grace is more convenient and powerful than immortals, and even possesses magic called miracles, it unexpectedly falls short of the great achievements of the ancients."

This feeling is like suddenly discovering the remains of a nuclear reactor during an archaeological excavation—it's perplexing.

"Whether it's mindset or ability, we should constantly break the rules and push our limits in order to become stronger."

The two found a secluded cave, and after making simple damage to the rock walls to prevent monsters from appearing and disturbing them, they began their research on Alphia's magic.

Ciel sat cross-legged on the ground, his palm transforming into a megaphone using the [Sound-Sound Fruit], emitting a 'bang bang bang' sound.

“There is no sound in the world, only vibration. Before, I used your gospel magic to achieve what you could not, to the point of shattering the earth, simply by changing the source of the sound.”

Xia Er manipulated the loudspeaker to create a shockwave, which slammed into the rock wall with a loud bang.

"As you can see, the Gospel you used before was entirely based on the magic within your own body, producing vibrations. Even with the blessing of [Silent Eden], the damage to your own body was still terrifying."

Alfia pondered, "So, you simply release your magic outside your body, and then release the [Gospel] magic?"

"Yes, it transfers the source of the [Gospel] from the magic within the body to the air, the earth, or the enemy, creating a larger-scale tremor. In other words, it disperses the magic that was originally concentrated into other things around it."

The power of Alfia's [Gospel] mainly comes from the concentrated, ultra-high decibel shockwave. Enemies hit by it will have their internal organs and eardrums explode. Even if they are only grazed, the sound from the shockwave will affect their physical abilities.

In contrast, Ciel spreads the shockwave to other things.

To put it simply, it's just a change in form.

The principle is very simple. As long as a mage like Alfia understands the principle, he can get started immediately.

In the future, Riveria will also be able to create a frost path thousands of meters long from the Fimbulwinter; Ryu has also used the Wind Ball of Light to fly and used the Star Flower (Rasengan) which is similar to Arish's Flame Flower.

This is an essential ability for high-ranking mages; it's not a new skill.

After a brief attempt, Alfia quickly mastered the technique. As she gently tapped the air, a faint crack appeared, and gusts of air blew away Charles's bangs.

"Magic seal, can't we see any tangible effects?"

"To be able to do this under the pressure is already quite good."

This was merely a review of previous development capabilities. Xia Er's expression turned solemn as he issued himself a decree.

He pounded his chest, making a drumming sound; he lowered his head, making a DJing sound; and he pressed his teeth, making an electronic keyboard sound.

Invisible slashes appeared on the cave walls, and inexplicable explosions occurred in the air.

Alfia was stunned. Someone actually treated her like a musical instrument. She had never seen anything like it before.

But Charles quickly broke free from the simple attack experiment, his eyes sparkling with starlight.

"Did you know that vibration can actually do many things? For example, through high-frequency vibrations of tens of millions of times per second, a blade can easily cut through steel."

Sounds at specific frequencies can also help us detect terrain, organisms, and other features within a range of several kilometers.

Sound can even help heal injuries; or interfere with the five senses to create illusions.

"Your magic is suppressed right now, and your decibel level is limited. Perfect, let's try to hear sounds from the other side that the human ear can't detect. Let me tell you what ultrasound is."

Chapter 294 Listening to the Voice of All Things

"The applications of sound waves are very wide; on a grand scale, they can even be related to the origin of all things."

Charles set the tone first.

"Based on my understanding of 'sound,' it can be divided into two aspects: first, the 'loudness' of sound, which we've been using before; and second, 'frequency.'"

Sonic weapons can be mainly classified according to frequency into: infrasonic weapons, high-intensity sonic weapons, and ultrasonic weapons.

Based on size, they are divided into: noise wave weapons and clustered sound wave pulses.

Ciel broke down the practical applications of various abilities into a concise and detailed description.

"It can be roughly divided into three directions: perception, control, and destruction."

Alfia seemed to be deep in thought.

What Ciel depicts are simply magical manipulation techniques. The original high-decibel loudspeaker has been transformed into a more precise "wave".

"Infrasound weapons have a very low vibration frequency, so they have no effect on ordinary objects. However, once they resonate with the vibration frequency of something else, they can trigger various powerful effects," Xia Er explained.

"For example, resonance can stimulate the brain, causing mental confusion, mania, and so on..."

"High-powered sonic weapons can cause people to tremble, feel fear, or even fall into a coma."

"Ultrasound has a wider range of applications: wide-area detection, endoscopy, sonic scalpel, hypnosis, etc..."

After gaining a basic understanding of the principles, Alfia attempted to mimic the abilities released by Sharl, and began to change the direction of her own magic release.

Let's start with the simplest form of destruction.

Ciel's ability to create a guaranteed hit "sonic slash" that ignores distance using the Sound-Sound Fruit, as well as his ability to trigger a fire explosion inside the enemy's body, is truly amazing.

Wherever Ciel's music can be heard, Ciel's attacks will hit.

"The first step is to let the sound waves permeate the battlefield, giving objects within range a wave of the same frequency. Then, using this frequency, a corresponding destructive wave is released to strike the target head-on."

Alfia attempted to activate a magic circle, the gray patterns extending outwards to cover an area with a radius of 500 meters.

"Gospel……"

hum-

Unlike the violent bursts of magic in the past, Alfia completely squeezed her limited magic power into the magic circle, which amplified it and swept through the labyrinth walls to a location several kilometers outside the magic circle.

"Snap!" Alfia snapped her fingers.

Somewhere in the arena, a bloody gash suddenly appeared on the body of a savage knight, his eyes rolled back, and he crashed heavily to the ground.

It didn't know who attacked it until its body was completely devoured by its own kind.

Alfia opened her eyes in surprise: "I think I saw... my attack."

"Also, there are monsters approaching us from nearby. To our left are three skeleton sheep, expected to arrive in three minutes and thirteen seconds."

“It’s the effect of the ‘radar,’ right?” Charles also closed his eyes and listened quietly.

He didn't have Alfia's ability to distinguish monster species by sound.

The Sound-Sound Fruit is somewhat different from the Sound-Sound Fruit. It belongs to the category of superhuman abilities, and its main effect is to transform the body into a special musical instrument to produce different sounds.

At most, the resonance can be altered through melody.

It's more accurate to call it the Sound-Sound Fruit than the Musical Instrument Fruit, as its effects are similar to those of the Weapon Fruit.

If it is a Sound Fruit, after awakening, it can change all sounds outside the body, alter all sounds within its range, and even control the activities of all living beings.

But the Sound-Sound Fruit... turns the surroundings into a grand theater? A world full of musical instruments?

From this perspective, using the [Silence-Silence Fruit] would actually be more suitable for developing Alfia's abilities.

Eliminating all sound (vibration) within range—that effect is terrifying.

at the moment……

Charles had just mastered his abilities and didn't have many techniques to develop. He didn't expect to create any powerful abilities in seven days. His main goal was to provide Alfia with ideas.

However, when Alfia mentioned seeing a monster, Sharl suddenly realized something and tentatively asked:

"Let's see if we can sense the opponent's next move based on the sound?"

All movement in the world is a form of sound. If one can use sound to distinguish the collision and vibration of muscles and bones, one can easily predict the enemy's attack.

It can even detect the opponent's most vulnerable point through sound resonance.

To take it a step further, could we use sound resonance to shatter the magic stone directly?

Alfia nodded, and instead of dealing with the three wandering skeleton sheep beforehand, she went to meet them.

Despite the weight of the collar making Alfia's movements clumsy, she didn't make any unnecessary gestures. She attacked and dodged simultaneously, flitting about like a butterfly on the edge of the monster's blade.

Charles was very nervous: "How are you feeling?"

Alfia casually brushed aside the monster's claws, reached directly into the skeleton sheep's body, and retrieved the magic stone hanging inside the skeleton.

Staring at the three assassins who had turned into black powder, Alfia lowered her head and recalled:

“In the past, I occasionally had similar ‘premonitions,’ but there was too much background noise, and it wasn’t as clear as what I ‘hear’ now.”

Limited field of vision, physical burden, and suppression of magic.

Only in this environment could Alfia fully unleash her talents.
