Asta's silly laughter and the surge of magic power from Yuno's direction brought Ryoma back from his regret over the mountain of gold.
He looked at the two guys. One had obtained a new sword, and the other had obtained the Wind Spirit Sylph.
Ryoma looked around. The mountains of gold and silver were dazzling, but these were all external possessions. Moreover, he couldn't move them.
"Damn it…"
He once again felt a pang of heartache over Finral's absence.
However, this was the treasure vault of an ancient dungeon, where treasures had slumbered for an unknown number of years. It shouldn't be possible that only those two things were special.
Asta had a special mana-less body and the five-leaf grimoire.
Yuno was the one chosen by the Wind Spirit.
It was reasonable for them to find their own opportunities.
And himself…
Ryoma looked down at the unique silver-white grimoire floating at his waist.
He was a transmigrator. He also possessed the unique second origin.
There was no reason for him to leave this place empty-handed.
Thinking this, Ryoma's fighting spirit reignited.
He no longer looked at the sparkling gold and silver jewelry but closed his eyes, trying to sense the flow of magic power around him.
He concentrated all his spiritual power, letting this faint energy spread out like a radar.
One second.
Two seconds.
Ten seconds.
Aside from the magic power fluctuations emanating from his companions and the chaotic aura from the magic tools, he found nothing.
Did he really overthink it?
Just as Ryoma was about to give up—
Suddenly, in his perception, an extremely faint but incredibly clear resonance appeared.
The feeling was very peculiar. It wasn't like magic power, it was more like a… resonance.
Found it!
Ryoma suddenly opened his eyes, his gaze accurately fixed on an inconspicuous corner deep within the treasure vault.
He didn't make a sound. He just silently walked over, and waved his hand, gently pushing aside the obstructing items.
Behind the pile of treasures was an ordinary-looking wall. But Ryoma could clearly feel that the resonance came from the other side of the wall.
Another hidden space?
It seemed the designer of this dungeon enjoyed playing such tricks.
Ryoma stretched out his hand, and ice-blue magic power gathered in his palm. He didn't choose to break it open violently but instead infused Ice Magic into the cracks of the wall.
Silently, the wall's structure was disintegrated by the low temperature, turning into a fine ice crystal dust that fell rustling.
Behind the wall, there was indeed another world. This was a smaller secret room than the one Asta had found, only a few square meters in size.
In the center of the room, there was a stone platform. On the stone platform, an ancient leather scroll was quietly placed.
It didn't have the gentle breeze surrounding the scroll Yuno found, nor did it emit any light. It looked like an ordinary piece of parchment, rolled up and tied with a faded leather string.
Ryoma took a deep breath and walked in. He stretched out his hand, his fingertips slowly approaching, but he didn't touch it immediately.
Who knew if this thing had any strange restrictions? It was better to try to investigate with magic power first.
However, the moment his ice magic power approached the scroll, it disappeared without a trace.
Was it absorbed?
Or was it isolated?
Ryoma frowned slightly, then mobilized a surge of spatial-temporal magic power within him, cautiously probing it.
This time, there was no obstruction. The power easily made contact with the scroll.
Safe.
After confirming this, Ryoma no longer hesitated, his fingertips gently touching the surface of the scroll.
The moment he touched it, the ancient scroll seemed to be activated, and the leather string binding it instantly turned into dust.
Immediately after, the ancient characters within the scroll suddenly came alive, no longer rigid symbols, but like flowing silver light points.
Buzz!
Countless silver light points broke free from the scroll's restraint, transforming into a stream of silver light, instantly surging towards Ryoma's waist.
The target was his silver-white grimoire.
"What?!"
Ryoma was startled. This change happened too fast, he had no time to react.
The grimoire at his waist automatically floated in mid-air and opened on its own.
Whoosh—
The pages turned to the blank first page, and the silver stream of light poured into that blank page.
Sizzle—
The stream of light quickly moved, reorganized, and solidified on the page, eventually forming a completely new magical script that Ryoma had never seen before.
The entire process took only two or three seconds.
Then a powerful and mysterious fluctuation spread out violently, centered on Ryoma. The entire treasure vault trembled because of it.
"Hmm?"
"This magic power is…"
"It's from Ryoma's side."
Asta, who was cheering for his new sword, Klaus, who was trying to maintain his noble demeanor, and Noelle and Luck, all turned their heads in surprise almost simultaneously, looking towards that inconspicuous corner.
They only saw a flash of silver light that quickly vanished.
Ryoma stood there, a grimoire emitting a soft glow floating in front of him.
"Ryoma! What did you find?!"
Asta, carrying the demon-slayer sword, shouted curiously.
As the light dissipated, the grimoire slowly closed, and flew back to Ryoma's waist.
What was that just now?
He could feel that his grimoire had a new page but he couldn't understand any of the characters.
If it was written into his grimoire, then does it record time or space attribute magic?
Or both?
It seems he'll just have to find an opportunity to slowly experiment with it later.
Although he didn't know exactly what it was, Ryoma had a hunch that his harvest this time would definitely not be inferior to Asta's and Yuno's.
Just then—
Boom!!!
An earth-shattering roar, without any warning, came from outside the treasure vault.
The sound was as if something huge had been forcibly destroyed.
Immediately after, the entire dungeon began to shake violently.
"Ahhh! What's going on?!"
Asta was thrown off balance, almost falling.
"An earthquake?!" Mimosa quickly grabbed a nearby pillar.
From the ceiling, dust and rubble rained down, and huge cracks began to appear in the massive stone roof.
"This is bad! This place is going to collapse!" Klaus's face changed dramatically as he roared.
Rumble!
The collapse began. Huge chunks of stone fell from the dome, smashing large pits into the mountain of gold before them, sending countless gold coins and gems scattering.
"Let's go!"
Ryoma reacted, shouting loudly.
"Yuno!"
Without his reminder, Yuno had already sprung into action. He took out his grimoire, and a fierce wind gathered.
Wind Creation Magic: Heavenly Wind Ark!
A streamlined airship made of gale winds instantly formed, hovering steadily in mid-air.
"Hurry up!" Yuno shouted.
Everyone dared not delay for a moment, scrambling onto the ark.
Ryoma was the last one. As he jumped on, he casually scooped up a handful of glittering gems and stuffed them into his pocket.
"Hold on tight!"
With a low shout from Yuno, the Heavenly Wind Ark instantly transformed into a streak of light, rushing towards the way they came from, which was the large door Asta had split open.
The airship was incredibly fast, nimbly weaving through the collapsing treasure vault.
Ryoma stood at the bow, cold air emanating from his body, instantly freezing several huge rocks that came crashing towards them into ice crystal, then shattering them with a punch.
Boom!
Ice shards flew.
The Heavenly Wind Ark successfully rushed out of the treasure room.
The situation outside was even worse. The entire dungeon structure was collapsing, passages were constantly caving in, and everywhere there was rolling dust and falling giant rocks.
The moment the airship rushed out of the treasure vault, Ryoma's gaze subconsciously swept over the spot where Mars had been defeated earlier.
It was… empty.
Not only was Mars gone, but even the restraints Klaus had created with magic were shattered on the ground.
Ryoma's pupils constricted, and he immediately looked at Klaus.
"Klaus! Where is Mars' grimoire?!"
Klaus was stunned by the question, subconsciously reaching into his pocket, then his face changed dramatically.
"It's gone! When did it…"
Ryoma's heart sank.
The culprit was gone, and the grimoire was also gone.
Coupled with the huge destructive sound just now…
This was no accident, someone had broken in from outside and rescued Mars.
However, now was not the time to worry about such things.
"Ahead! It's going to collapse!" Noelle screamed, pointing forward.
They saw the entire ceiling of the passage in front of them crashing down, about to completely block their path.
"Leave it to me!"
Ryoma's eyes narrowed, and he pushed his hands forward.
Ice forcibly propped up the giant rocks blocking the way, clearing a path. The Heavenly Wind Ark passed through without stopping.
They sped through the collapsing palace, each turn accompanied by giant rocks narrowly scraping past them.
