Weakest Beast Tamer Gets All SSS Dragons

The silence that followed the hyena’s scream was deafening in its own way.

Nobody in the stands understood what they were witnessing before their eyes. A Gold-rank sonic attack that should have been utterly devastating to any creature… completely and totally ineffective against what appeared to be a Gold-rank beast standing there like it was made of solid diamond.

Master Lin stared at the hydra with narrowed eyes, her experienced gaze trying to understand what defensive technique could possibly explain this immunity. But even she couldn’t detect any active defenses around the creature.

Ren smiled slightly with satisfaction at the demonstration’s success, pleased with how this was unfolding.

The hydra wasn’t just powerful in offensive capability through its two independent heads and their beam attacks.

It was an absolute defensive wall that could withstand punishment that would obliterate most other beasts.

And now everyone watching would understand precisely why he’d chosen it for this particular matchup against the hyena.

The hyena could scream all it wanted with its maximum power.

The hydra wouldn’t feel a single thing from the assault.

Liu stared across the arena at Ren with dawning comprehension in his eyes. Understanding that he’d just revealed his best attack, his strongest offensive capability…

And it had accomplished absolutely nothing against his opponent.

Several spectators began theorizing out loud, trying to make sense of what they’d just witnessed.

“Perhaps it has some kind of magical resistance we don’t understand…”

“Or maybe a less visible barrier than the one Ren manifested, something we simply failed to notice.”

But the few observers who possessed mana-enhanced vision shook their heads upon hearing those types of suppositions. There was no ambient mana circulating around the hydra’s body. No defensive barriers that their enhanced sight could detect.

“Could be that… sound doesn’t travel well through those transparent scales for some reason…”

“No,” a voice called out from the upper stands with authority that came just from being older. It was an eighth-year student who’d been observing carefully. “That doesn’t make any sense at all. Glass shatters easily with sounds and vibrations far less intense than what we just witnessed.”

That last theory gained traction rapidly through the crowd.

It had superficial sense but it appealed to people. Perhaps the hydra’s scales that appeared crystalline in nature functioned similarly to glass in their acoustic properties.

But there was an obvious and fundamental problem with that particular theory.

Finch, who had done the unthinkable thanks to not being as financially constrained anymore due to his new second job courtesy of Ren’s generous employment, had requested the day off specifically to watch his favorite magnate in action.

‘The day off! ME!!’ Finch thought.

He adjusted his broken glasses with careful fingers while Theodore cleaned some of the crystal fragments that had fallen earlier and still clung to his worn suit.

“Crystal, like fine wine glasses or my spectacles here, is vulnerable to acoustic resonance,” Finch began with the slightly pompous tone he adopted when explaining any concepts. “If a sound matches the natural frequency of the crystal material and is sufficiently loud (Author’s Note: roughly 105 decibels based on standard measurements) the glass vibrates with such amplitude that it shatters. The material is too inelastic to absorb the vibrational energy, so it fragments catastrophically!”

He paused dramatically, studying the hydra’s scales more closely with his damaged lenses.

“But those scales…” he continued slowly, building suspense. “Aren’t crystal at all. They’re…”

He stopped with theatrical timing. His eyes widening in feigned recognition despite barely being able to see anything through the broken lenses.

“Diamond,” he murmured with perfect emphasis.

The word dispersed through the stands like its own shockwave spreading outward.

“Of course, the hydra has diamond scales instead of normal ones…”

“And how is that different from crystal? Aren’t they similar?”

♢♢♢♢

On the field below, Ren smiled slightly at hearing the discussion drift down from the stands.

His hydra’s scales had the perfect form and distribution for maximum defensive capability. They weren’t just hard and filled with concentrated mana for enhancement…

They were also layered over elastic sections and other hard sections between the internal layers, overlapping when in resting position but allowing a wide range of mobility during movement.

Thus avoiding the common problem where a diamond defense possessed only hardness without toughness to absorb impacts.

Not all of the hydra’s scales were pure continuous diamond, that would be too uncomfortable, too inflexible for a creature that needed to move. But all of its external parts had sufficient crystalline carbon structure to share the key defensive properties.

And one of those crucial properties was almost absolute resistance to damage from sonic attacks.

In the stands, Finch continued his explanation with his voice gaining even more theatrical confidence as people paid attention.

“Diamond may appear somewhat similar to crystal, but it’s extremely resistant to noise-based damage. Unlike crystal which shatters when exposed to high-pitched sounds, diamond is practically ‘deaf’ to any destructive resonance.”

He gestured with his hands to emphasize the point.

“The properties that give diamond its legendary hardness (AN: the atomic carbon bonds) are so rigid and compact that its natural resonance (frequency) exists far beyond the range where sound-based attacks can affect it!”

[Author’s Note: Diamond’s resonance frequency operates in the trillions of hertz, compared to the roughly 1000 hertz range of human hearing sensitivity. To actually damage diamond with sound alone would require sonic energy that’s physically impossible to generate in our atmosphere… we’re talking about decibel levels that only exist at the center of nuclear explosions or cosmic events. Sound also travels through diamond at approximately 12,000 meters per second compared to 340 meters per second in air, but traveling fast doesn’t mean causing damage, it simply passes through without affecting the molecular structure. ¯\_(ツ)_/¯ Wanted to say it in the story but Finch can’t break the 4th wall with modern knowledge that much!]

He paused to ensure others in the crowd understood the implications.

“The golden banshee hyena, even with its powerful attack enhanced by mana infusion, isn’t even remotely sufficient to overcome that fundamental material property.”

Finch’s basic explanation but somehow fully true… rippled through the audience as understanding dawned on more observers.

The hydra hadn’t needed to defend itself at all.

Not because it possessed some invisible magical barrier they couldn’t detect.

Not because the attack had somehow failed to connect properly.

But simply because its diamond scales were functionally immune to the specific type of damage that the hyena could inflict through sonic attacks.

It was a perfect counter matchup. A beast whose primary attack was sound-based confronting a beast whose defenses had the ideal composition, whether through fortunate luck, natural evolution, or Ren’s intentional cultivation methods… to nullify that attack type completely.
