A complex combination of legal-category and causal-category spells.

It's been a while, has the current "Nine Commandments Secret Meeting" become this powerful?

After listening to Catherine's serious and solemn narration, Ronald had only this thought in his mind.

After all, spells of this magnitude.

Just from the literal meaning, they're quite something.

Once the initial surprise passed, his thoughts returned to calm reflection and speculation.

With just a little imagination, Ronald came to a conclusion by analogy:

"Catherine, this is just a city on the border of the 'Nine Commandments Secret Meeting' territory. From this, it's conceivable that their headquarters might also have this kind of thing, perhaps even more powerful."

Catherine shrugged:

"Using this doesn't necessitate the original canon to oversee, so your speculation might very well be reality."

"What about a solution?" Ronald turned his gaze to the other side, looking somewhat hopeful at Costate.

Because his maid had considerable expertise in breaking barriers.

However, Costate shook his head shamefully:

"Sir, I'm skilled at dealing with physical barrier defenses. There's really no good method for this type of causal-category spell."

Even Costate had no solution, and Ronald almost accepted this as the first quandary since coming to this continent.

But at that moment, Catherine suddenly spoke:

"Ronald, there's no need to look so glum. Didn't I just mention—causal-category spells were an important research topic back at Barrier Mountain."

Ronald perked up:

"You have a way?"

Catherine flashed a wild smile:

"Simply put—fight fire with fire." 𝘧𝓇𝑒𝑒𝑤ℯ𝑏𝓃𝘰𝑣ℯ𝘭.𝘤ℴ𝘮

"This type of spell seems unsolvable, but there are actual signs it can be overridden. With casters of our level attacking, a relentless barrage can surely exceed the threshold and completely destroy it."

The fruits of combining causal-category and legal-category spells, can they really be destroyed by sheer violence?

Ronald's face clearly displayed disbelief.

Catherine noticed and continued to explain with a smile:

"Ronald, don't underestimate yourself. These spells are indeed formidable, and ordinary casters trying to breach them violently wouldn't work. But you and I are not ordinary casters; we're bearers of the original canon, even at the highest level of existence!"

As she spoke, an aura naturally emerged from the young woman, adding a touch of contempt to her tone.

"For us, to destroy some formidable thing, the effect of overwhelming force has reached the level of a qualitative change."

Catherine's words triggered Ronald's contemplation.

After reconsidering many things, he pressed on with questioning:

"So if we want to get in now, we just need to attack randomly?"

"Pour your power into the city center!" Catherine coldly pointed to the city below, "Anyway, we'd have to do it again at their headquarters later; this city can just be a practice run!"

As her sentence finished, the magic fluctuation emanating from Catherine's body became violent.

Ronald was about to follow suit but snapped out of it just before chanting a spell—he realized he'd been led into a trap by Catherine!

"Wait, hold on!"

"Catherine, if we act like this, what will happen to the city's residents? And if we make such a big scene, the enemy will surely be alerted!"

"..."

The surging magic power from Catherine stopped abruptly.

"Perhaps they've already used a prophetic spell to know we're coming, so we don't actually have to worry about that, do we?"

The tower master of the Astronomical Department was originally ready to make a move, already quite close. But in responding to Ronald's query, she didn't even bother to look back.

Ronald flew forward, circling around to see Catherine's expression.

She had a face of dejection and frustration, her eyes drooping wearily at the corners.

Ronald continued to press:

"Also, my first question—what would happen if we attacked the city indiscriminately?"

"Heh—" Catherine sneered, "those who aid the wicked, what else? If they're unlucky, they'll just die!"

This reply completely quashed Ronald's earlier plan.

He sighed, returning to analyzing the situation:

"We've been here for such a long time, and no one has come to check. This shouldn't be due to slowness on the part of the city's casters, right?"

Catherine was candid in this regard:

"This kind of spell generally operates autonomously. After being set up, it's difficult for the overseer to monitor even if they want to."

"Ronald, in this situation…"

Catherine tried to say more, but Ronald waved his hand, stopping her attempts to persuade further.

"Catherine, we've discussed this before; I don't want to become an enforcer controlled by violence."

Seeing Ronald's resolute attitude.

Catherine didn't persist, shrugging as she fell completely silent.

Meanwhile, Ronald began a new round of analysis.

Firstly, from the perspective of spells—

The impact of fighting fire with fire was unacceptable to him; breaking it with spell theory was fraught with difficulties and almost impossible.

But thinking from other angles, such as the "Nine Commandments Secret Meeting" itself?

Ronald's thoughts started flowing smoothly.

The "Nine Commandments Secret Meeting" is currently a power.

Moreover, it is a large power with substantial land holdings and intricate interests.

In such a situation, it inevitably faces interactions with other powers.

Among them are certainly those who harbor hostility towards them.

Would the "Nine Commandments Secret Meeting" allow these spells to exclude everyone?

——That is surely impossible.

From a diplomatic perspective, they would definitely set a backdoor to allow those who, while hostile, need to enter the city. Based on Ronald's understanding of legal-category spells, this is a change easily accomplished.

With this thought, Ronald naturally confirmed with his companion:

"Catherine, if causal spells can modify trigger conditions using legal-category spells, then adding an identity-based trigger exemption should also be possible, right?"

"To come up with this so quickly, you are indeed impressive." Catherine nodded slightly, affirming Ronald's conjecture, "To my knowledge, this is feasible."

Upon hearing this, Ronald truly sighed in relief:

"Then it will be easier."

"We need to obtain an identity, one that allows us to 'legally' enter."

"This way, we can ensure we don't cause too much commotion; at the same time, our identity won't be exposed, nor will we attract excessive attention from the 'Nine Commandments Secret Meeting.' "

Ronald made a judgment, and his actions were decided.

Almost immediately afterward, Costate spoke up, suggesting the simplest and most suitable choice for them:

"Sir, shall we seek Miss Claudia's assistance?"
