After the slave owners went bankrupt, they all wanted to keep me as a mistress.

He looked closely and saw that the treasure chest contained only a pale purple crescent-shaped key; otherwise, it was empty.

"what is this?"

Mu Qiu picked up the crescent-shaped key and frowned slightly.

Vera leaned closer, blinked her big eyes, and then stared intently at the crescent-shaped key.

Under Mu Qiu's expectant gaze, she slowly shook her head:

"Hmm! It's a key I've never seen before!"

"..."

Mu Qiu's lips twitched.

If you've never seen it before, why are you thinking about it for so long?

Serafia also said softly, "This should be a key used in the dungeon, perhaps to open a treasure chest or a door, or maybe it's a key used in other dungeons."

Mu Qiu asked in surprise, "Can treasure chests contain items that can only be used in other dungeons?"

"Of course!"

Vera, fearing that Seraphia would usurp her encyclopedic status, preemptively educated her master on dungeon trivia: "Because dungeons and the abyss have a very deep connection, and in the very beginning, all the abysses were connected, unlike now which are divided into seven abysses. In the past, there was only one abyss!"

Therefore, scholars generally believe that there is actually only one dungeon, which is why key items from one dungeon can drop in another!

"Unlike the Abyss, the entrances to the dungeons were initially scattered throughout various places, but later the number of passages increased, and the dungeons even became interconnected."

"If this is not stopped, sooner or later all the underground cities will be connected and become one super-super-super-large underground city!"

As Vera spoke, she deliberately puffed out her chest, as if to say that she was also very large.

Mu Qiu asked, "What would happen if all the dungeons were connected?"

"do not know!"

Vera answered very decisively.

"Since nothing like this has ever happened before, of course no one knows the outcome. But according to the astrologers' predictions, if the dungeons are connected, then the abyss below is very likely to be connected as well. At that time, the power of the abyss will be strengthened. In short, it is a very terrible thing."

"Weakening the power of the abyss and curbing the growth of the dungeons are things that only the brave Nene can accomplish."

Mu Qiu touched his chin.

If that's the case, wouldn't revealing my identity as the hero mean I'd be busy saving the world?!

Anyway, we can summon the hero again in another hundred years, so let's let him go this time!

Compared to saving another world and then dying of old age two or three hundred years later, isn't it more appealing to go back to the original world and be Happy Superman?

After the key was taken out, the treasure chest disappeared from the spot.

"Master, there seems to be a passage here!"

Fiona suddenly noticed that where the treasure chest had disappeared, a crack had been revealed in the rock wall behind it.

The crack, which was originally hidden by the rock texture and treasure chests, has now become visible.

It was pitch black inside. She threw a pebble down, but didn't hear a sound for a long time. Clearly, this downward passage led to the deeper parts of the underground city.

"Hidden passage?"

Seraphia leaned closer and sensed the dense magical energy emanating from it. Her expression turned serious: "This energy... is very uncomfortable."

She extended her legendary perception deep into the channel.

A moment later, Serafia's face, covered by a black cloth, revealed a look of shock: "This passage... must have appeared not long ago, and the end it connects to... seems to be another large underground city!"

Mu Qiu asked, "Want to go in and take a look?"

Serafia hesitated for a moment, which was uncharacteristic of hers, and then shook her head.

"No, this passage is too narrow. If the underground city blocks move again, it may close, and then we won't be able to get out."

"When encountering a situation where a medium-sized dungeon connects to a large dungeon, it's best to use an alchemy doll to explore. Unfortunately, I came in a hurry this time and didn't bring an alchemy doll with me..."

Mu Qiu hesitated for a moment, then asked, "So, should we go back now or...?"

Serafia pursed her lips and said:

"Let's continue exploring down through the normal passages first. We need to figure out how many hidden passages appeared after this underground city riot."

"Then let's continue on our journey."

Mu Qiu nodded.

It's a medium-sized dungeon, and the highest-level monsters there are only Orichalcos. At this rate of clearing, the main passage of the entire dungeon can be cleared out by tonight at the latest.

However, this meant they would have to spend the night in the wild.

Mu Qiu glanced at Serafia subconsciously.

I wonder if Miss Saintess brought a tent?

He usually doesn't buy many inexpensive items to avoid taking up space in his storage ring, so he only prepared one tent.

……

at the same time.

Inside the Silver City, in the largest underground arena.

"Ladies and gentlemen, welcome to the largest arena in the Silver City—the Crimson Arena!"

A loud voice rang out from the high platform.

"Today's final battle is the one you've all been eagerly anticipating!"

"Our challenger is the undefeated silver-ranked Valkyrie Kalista, who has achieved a 49-game winning streak with 1 draw and 0 losses!"

"The challenger is the barbarian with 147 wins, 39 draws, and 13 losses—Gorehowl Skullbreaker!"

"He has been at the peak of Silver for fourteen years, just one step away from Gold, making him a half-step Gold level existence!"

The commentator's tone became impassioned: "Will the undefeated Silver Valkyrie continue her winning streak, or will this near-Gold Barbarian shatter the Valkyrie's undefeated myth?!"

"Now, it's time for our distinguished guests to place their bets!"

"..."

Outside the venue, in a separate room.

Kelly pushed open the door and saw the woman inside training with a long spear in her hand.

The woman was tall with long, straight legs, healthy tanned skin, and long, dark brown hair that reached her waist.

With each swing of her spear, her voluptuous thighs trembled with a throbbing sensation that made men's blood boil. Sweat trickled down her slender waist and into her undulating curves. Even in leather armor, the astonishing curves of her full breasts and hips could not be concealed.

“Kalista, this is your potion ration for today.”

Kelly went inside, placed the potion on the table, and wasn't annoyed that the woman didn't respond.

As the person in charge of the other party, she had long been used to Kalista's willful attitude. During this period, she had also made a lot of money from the other party, and the relationship between the two parties was relatively harmonious. She had also helped the other party refuse several requests to accompany her to drinks.

Unfortunately... in the arena, gladiators as flamboyant as her rarely live long.

Kelly cast a slightly pitying glance at the woman's retreating figure.

The outcome of today's duel was decided from the very beginning.

This Silver Valkyrie, who still retains her virginity, will be easily defeated by the barbarian after taking the Dark Elixir. Then, the barbarian will tear her clothes in front of everyone and do what the audience on stage has been waiting for most.

Poor little girl, did she really think their gladiatorial arena was a charity?

You've already sold yourself into slavery, and you still expect to win a hundred consecutive victories to escape that slavery? Do you think you can have all the good things in life?

Since you rejected the nobles who wanted to buy you and chose this path, your fate was already sealed.

Come to think of it, the one who orchestrated this ending was the very nobleman who first wanted to buy her, right?

Oh, right, there's something I haven't told her yet.

After she arrived at the arena, her younger brother was soon captured and taken to another arena. On his first day there, he was killed by the werewolves because of his weak physique.

And her seriously ill parents, the money they earned from selling themselves into slavery, had long been stolen by that group of scoundrels.

The mother, unable to afford medical treatment, eventually died at home. When the father went to demand money, he was beaten to death by thugs.

Starting two weeks ago, none of the letters she sent out were ever received.

She alone still held onto hope, training relentlessly every day, striving to achieve a hundred consecutive victories and escape the arena...

Kelly was initially hesitant about whether to tell Kalista about it.

Looking back now, I think it's better not to tell her. Let's leave her with a last bit of hope so that she won't suffer so much when she passes away.

Alas, this cannibalistic world...

Kelly shook her head, sighed softly, and turned to leave the room.

"Potion..."

Kalista stopped what she was doing only after Kelly left the room. She wiped the sweat from her forehead and was about to pick up the potion on the table.

But at that moment, a sudden, intense dizziness struck, and she vanished from her spot.

The next second, a mimic appeared in the room with a bang.

It instinctively picked up the potion and drank it all in one gulp.

boom--!

The moment the potion was ingested, the magic within the mimic's body instantly became agitated.

And the aura emanating from it was... peak of the Orichalcum!

No one knew that it was the culprit behind this dungeon riot, a level 50 mutated lord, a mimicry mimicry chest monster!

"Oh... is this the human's battle potion? I feel my body getting hot too, is it my killing intent surging!"

After drinking the potion, the mimic seemed to become interested, transforming into one female figure after another, until finally... its gaze settled on a magic crystal next to it.

Soon, as the smoke dissipated, it transformed back into Kalista's appearance. If you looked closely, you would notice that it still had some differences in appearance from the Kalista from before.

This is because it is merely a simple mimicry of the image through the magic crystal, rather than a complete mimicry after devouring the target.

After completing its mimicry, it casually picked up a long spear and swaggered out of the room.

"Being able to fight as a human is truly exciting! I've long since grown tired of that dark dungeon. I wonder if there are any powerful opponents out there who can give me a good time..."

……

Seven hours later, deep within the underground city, on the fiftieth floor.

Mu Qiu stomped on the slime under his feet with a puzzled look, blinked, and said, "Seraphia, the lord of the fiftieth floor is actually a Black Iron level slime?"

"Do not……"

Serafia shook her head, a look of confusion in her eyes.

"The lords here change every time they refresh, but they are at least early-stage Orichalcum, and at most peak-stage Orichalcum..."

“A Black Iron-level slime… cannot become a lord of the final level unless someone deliberately placed the slime in this place.”

As she spoke, Serafia took a slight breath and said softly, "We've basically cleared out the monsters here. Now we can go back to the Adventurers' Guild to post a quest and ask everyone to help us find the hidden passage."

Mu Qiu nodded slightly.

After accompanying Serafia on her journey, he also understood the solutions to the underground city uprising.

First, high-level adventurers should clear out the mid-to-high-level monsters that appear in the lower levels. If possible, it would be best to sweep through the entire dungeon in one go. Then, the main passage should also be swept through in the same way. On the way back, check as many hidden monsters as possible.

After that, the task of exploring the new passage was left to a large number of adventurers.

Once the number and location of the new passages are determined, alchemical dolls will be used as an advance team to explore. If two dungeon passages I are found to be connected, the cities responsible for those two dungeons will cooperate with each other...

"Miss Serafia, shall we return now?"

Seraphia shook her head. She surveyed the cave on the fiftieth level and said softly, "Traveler, if you don't mind, we'd better spend the night here."

"Staying here overnight?"
