Here's the English (US) translation of your web novel passage, keeping the grammar polished and the writing smooth:
After changing into fresh clothes and tidying myself up in front of the mirror, I was finally ready to face the day.
My goal was clear—register as an adventurer, gather information about this era, and most importantly… find my younger sister.
After making sure everything was in order, I stepped out of the inn and headed straight for the Adventurer's Guild.
From the outside, the guild building looked grand and well-maintained—far different from the image I had in my head. In the past, adventurer guilds were usually messy, with bulletin boards covered in scribbles, rough wooden tables, and the overwhelming stench of alcohol.
But here?
The guild was built with elegant architecture, featuring large glass windows and double doors adorned with intricate carvings of a sword and shield.
I hesitated for a few seconds before finally opening the door and stepping inside.
And the moment I entered—
"What the hell is this?"
My eyes widened slightly.
Not only was the building different, but the entire system had changed drastically.
In the past, the adventurer's guild was simply a place for adventurers to accept quests and report their missions. But now…
Inside this guild, several reception desks were manned by neatly dressed staff assisting adventurers in orderly lines. There was also a magic-based electronic quest board, where adventurers could simply touch their identification cards to accept missions.
I even spotted a large glass-walled room in the corner, where several people were training with magical combat simulators.
I let out a long sigh.
"This era has really advanced too much..."
But well, no use complaining about it.
I walked up to the reception desk, where a young woman with brown hair and a crisp uniform greeted me with a polite smile.
"Welcome to the Apex Adventurer's Guild," she said in a professional tone. "How can I assist you today?"
I placed my hand on the counter. "I'd like to register as an adventurer."
The receptionist nodded and took out a small crystal from beneath the desk.
"Alright, for the registration process, please place your hand on this Evaluation Crystal," she instructed.
I eyed the crystal with slight suspicion. "What's this for?"
"This crystal will read your base combat abilities and determine your initial adventurer rank," she explained.
I was slightly surprised.
"So now they have a system that can instantly measure someone's capabilities?"
Back then, you had to prove yourself by completing several missions before earning a rank.
But if they could assess it just by placing a hand on a crystal… this was far more convenient.
I exhaled and placed my hand on the crystal.
For a moment, the crystal trembled, then emitted a faint dark blue glow.
The receptionist glanced at it briefly before jotting something down on the document in front of her.
"Alright, the evaluation shows that you possess above-average combat abilities, so you'll start at Rank C."
I raised an eyebrow. "Not Rank F?"
"With these results, it wouldn't make sense to place you at the lowest rank," she replied with a small smile. "Normally, new applicants start at Rank F, but for those with notable combat skills, we can adjust their initial ranking."
I nodded, accepting her explanation.
After going through some administrative procedures, the receptionist finally handed me a small silver card.
"This is your Adventurer's Card. With this, you can accept quests from the mission board or the magic terminals in the corner of the room," she explained, pointing toward the electronic quest board.
I took the card and examined it for a moment.
"So now, everything is magically digitized, huh?"
Slipping the card into my pocket, I turned back to the receptionist.
"I have a question," I said.
"Of course. What would you like to ask?"
"I noticed some people coming in groups, and some of them are wearing special badges on their chests. Are they part of something?"
The woman smiled. "Ah, you must be new to Apex. The guild system in this era is slightly different from before. Now, in addition to working individually, adventurers can also join clans."
I frowned. "Clans?"
"Yes," she said, gesturing toward a bulletin board on the wall. "Clans are official groups recognized by the guild. They can be small collectives of adventurers with a shared goal, or large organizations working together to complete high-level missions."
I narrowed my eyes, processing the information.
"So, it's like a party… but bigger and more organized?"
"By joining a clan, adventurers gain various benefits," she continued. "Including access to exclusive quests, special facilities, and better resources."
I remained silent for a moment.
This system didn't exist in my past era.
Back then, adventurers either worked solo or in small parties, and the only distinction was their individual ranks within the guild. But with the introduction of clans, it seemed that adventuring had become more than just a solitary career.
I let out a quiet sigh.
"Looks like I'll have to start adapting to these new systems."
"Are you interested in joining a clan?" the receptionist asked with a professional smile.
I smirked slightly. "Not right now."
I wasn't the type to work in a group. At least, not yet.
"I'll take on a few missions first before thinking about clans," I added.
The receptionist nodded. "Of course. In that case, welcome to the world of adventurers."
I pocketed my Adventurer's Card, turned around, and walked away.
The first step was complete.
Now, it was time to adjust to this new era.
By late afternoon, I was searching for clues about my sister's whereabouts.
Since she had been sold into slavery, I figured asking around might yield some leads.
But all I received were cold stares and indifferent responses.
Some people ignored me completely, while others walked away the moment I mentioned anything related to slavery.
I was starting to realize something was different about this era.
And after digging a little deeper, I found my answer—
Slavery was illegal here.
Which meant there were official laws protecting the rights of all sentient beings.
I narrowed my eyes.
"How did it come to this?"
In the past, slavery was common, especially among nobles and royalty. But now?
As I observed more carefully, I began to understand.
This world was no longer inhabited by just one dominant race.
Walking through the streets, I saw a diverse population—humans, elves, beastmen, even dwarves and mixed-race individuals—all coexisting.
Civilization had evolved.
This was no longer a society ruled by a single race, but a system that allowed different races to work together without discrimination.
I had heard that a group of elite individuals had implemented these new laws—not because they were kind, but because they saw the economic and strategic benefits of cooperating with other races.
By abolishing slavery, they could form stronger alliances, expand trade, and create a more stable civilization.
However, I knew one thing for sure—
Just because something was illegal, didn't mean it no longer existed.
It just meant it had been pushed underground.
"If that's the case… I just need to dig deeper."
I didn't care whether the law forbade it or not.
All I knew was that my sister was out there somewhere—
And I was going to find her, no matter what it took.
