The Fukaros Familia, starting from DanMachi.

Fen Yu stared at the blue-purple vortex, and the corner of his mouth twitched involuntarily.

He already had a vague guess in his heart, and a sense of helplessness, "I knew it," welled up in his heart.

He glanced instinctively at the robin beside him and noticed that the intelligent deputy commander was also looking at him with a strange expression.

Clearly, the two of them were thinking the same thing.

"If I'm not mistaken," Fen Yu sighed, saying helplessly, "this is probably... my fault."

As he spoke, he took a step forward, reached out his hand, and touched the mysterious vortex.

The moment his fingertips touched the halo, he felt as if he were being pulled by a gentle force and instantly enveloped in a blue-purple light.

The next moment, a massive and clear stream of information flooded into his mind.

[Secret Realm Dungeon: Midsummer Courtyard]

[Dungeon Type: Artifact Dungeon]

[Secret Realm Introduction: With the loss of ancient civilization, the once magnificent summer palace and mausoleum have been buried underground. Perhaps only the ancient trees and bricks within still remember the past.]

[Number of participants limited to 1-10 people]

【怪物：Lv.1丘丘人x20，Lv.1冰史莱姆x10，Lv.1雷史莱姆x10，Lv.1水史莱姆x10，Lv.2变异雷史莱姆x3，Lv.2大型冰史莱姆x3，Lv.3冰深渊法师x1，Lv.3愚人众-雷莹术士x1。】

【掉落：圣遗物套装【行者之心】（3-4星）、【冒险家】（3星）、【如雷的盛怒】（4-5星），冒险阅曆书（随机提升冒险者1-100点能力值）】

[Clearance condition: Defeat all monsters]

[Entry Requirements: Offering Magic Stones]

[Limit of attempts: Three]

[Drop Restriction: The higher the level and the more players, the lower the drop rate.]

[Secret Realm dungeons appear randomly and disappear after being cleared three times]

At the same time, a sudden burning sensation came from the Divine Grace engraved on Fen Yu's back, as if responding to this anomaly.

It's quite obvious that it was the hidden effect of his skill [The Abyss of the Gaze] that caused the appearance of a "secret dungeon" that shouldn't exist in the dungeon.

"They've even created a dungeon, this is really..." Fen Yu sighed after processing the information in his mind.

He stepped back and said to his companions, who were still observing, "You guys go up and try it too, you'll know once you touch it."

Robin, Tifa, and Violet exchanged glances. Although they were filled with doubts, they chose to trust Burning Feather's judgment.

They stepped forward one by one, carefully reaching their hands towards the vortex.

In an instant, the same stream of information flooded into their minds.

"There's... such a thing?"

Robin withdrew her hand, her pretty brows furrowing slightly. She instinctively covered her forehead, her expression a mix of amusement and exasperation. "Monster information, loot list, entry requirements... isn't this just like playing a game?"

"This is way too difficult!"

Tifa's focus was entirely on the monster list. She took a deep breath, her tone grave. "More than fifty monsters, including a Level 2 mutant, and even... even two Level 3 monsters? Are these the kind of enemies that should appear in the upper levels?"

Everyone present understood what this meant.

This dungeon, called "Midsummer Courtyard," is far beyond the capabilities of even the most advanced adventurers.

Let alone Lv.1 adventurers, even an ordinary Lv.2 adventurer team would probably end up with one person dying as soon as they enter.

Fortunately, the information in this copy is completely transparent.

Not only the types and numbers of monsters, but also the items they drop are clearly listed.

This serves as a warning in some ways, preventing unsuspecting adventurers from recklessly venturing in and needlessly throwing their lives away.

But the other side of this warning is an irresistible temptation.

Those "relic" sets are one thing, but the [Adventure Album] alone is enough to drive any adventurer crazy.

The ability to directly increase an adventurer's stats by 1-100 points, regardless of talent or potential, is invaluable to any adventurer.

For adventurers who have already honed their abilities to the limit and are desperately seeking an opportunity to level up, this is an unattainable miracle.

More importantly, this promotion has no level restrictions.

This means that even top adventurers in Orario who have been stuck at Lv.6 for years and have made no progress can grow through this almanac.

You should know that at their level, improving even a single point of ability is incredibly difficult.

A small adventure book could potentially break through their stagnation that has lasted for many years.

It is foreseeable that once the existence of the [Adventure Album] is leaked, it will shake the entire Orario, and even the whole world.

To seize these three opportunities to enter the dungeon, the various clans will undoubtedly fight tooth and nail, even resorting to violence and bloodshed.

"Let's go inside."

Fen Yu made his decision almost instantly.

He was highly skilled and daring. The massive number of monsters and two powerful level 3 enemies in the dungeon did not deter him; instead, they fueled his fighting spirit.

He instantly understood the stakes involved.

This secret realm instance appeared because of him, but he is by no means the only one who can see and enter it.

Once this news gets out, it won't be so easy for them to enter safely again.

This first opportunity is absolutely not to be missed.

Robin and the others clearly understood this as well, and their eyes hardened.

"it is good."

Without hesitation, the four immediately began taking out the magic stones they had collected along the way from their bags and throwing them one by one into the blue-purple vortex.

The halo devoured the magic stone, and the vortex seemed to spin a little faster, but other than that, there was no other reaction.

When they poured all the magic stones they had—loot they had accumulated from the first floor all the way to the twelfth floor, worth at least tens of thousands of falies—into the pot, an awkward thing happened.

The blue-purple vortex remained suspended there silently, showing no sign of opening.

Not enough magic stones.

"...This dungeon is really good at consuming resources."

As the wallet manager of the clan, even the robin's lips twitched slightly.

Tens of thousands of magic stones were thrown in, but not a sound was heard.

Fen Yu felt a headache coming on.

His "Entangled Bonds" system was already a huge consumer of magic stones, and now there's another secret realm dungeon with an equally large appetite, so the financial pressure in the future is probably not small.

"We can't wait any longer."

Without hesitation, Fen Yu said to the three of them, "You stay here and guard the area, don't let other adventurers get close. I'll go collect the magic stones; one person can move faster."

After all, they have already invested such a huge amount of "sunk costs." If they leave now and are outmaneuvered by newcomers, they will suffer a huge loss.
