I established the Eternal Immortal Clan by taming beasts.

"Hehe, why not take advantage of free spirit stones!"

Qin Yulin walked briskly through the cave, in a rather pleasant mood.

Her eyes, hidden beneath the veil, curved into two crescent moons, and the fine lines at the corners of her eyes revealed a hint of smugness.

As she walked, she played with the emerald green jade box in her hand, which contained the Lingzhi mushroom she had just acquired.

Although a single Ganoderma lucidum isn't worth much, it's not bad to pick it up along the way. Even a small mosquito bite is still meat!

She put the jade box into her sleeve, put her hands behind her back, and continued walking forward along the passage of the cave.

She's recently run out of spirit stones to research formations.

Those array pattern materials, spirit ink, and spirit jade used for testing—none of them are free.

She counted on her fingers and realized that the materials she needed to purchase next month alone would cost nearly 600,000 spirit stones.

Just as he was wondering whether to go and trick his good apprentice into giving him some money, he received the news that the old cave had been opened.

Remembering something, a smile appeared on her lips.

Immediately, evil thoughts arose within him!

After disguising herself and buying a secret realm token, she quietly sneaked in.

That ordinary face was the result of a whole night of meticulous disguise; once the veil was on, even she herself couldn't recognize herself when she looked in the mirror.

As for the 70,000 spirit stones spent on buying the token through someone?

I'll owe it to you for now, and we'll talk about it when we get out.

"I remember we're almost there; it's one of those caves around here."

After searching for more than half an hour by relying on his memory, Qin Yulin finally found the original location.

She stopped at a fork in the road, her gaze sweeping back and forth between the two passages, then looking up at the glowing crystals on the cave ceiling, as if trying to confirm something.

The cave in front of us looks winding and twisting, much like other caves, with two openings at the front.

One side leads to the left, the other to the right; neither is wide enough for a single person to pass through.

The passage was pitch black at its depths, with no end in sight, only faint fluctuations of spiritual energy emanating from within.

Qin Yulin neither turned left nor right.

She continued forward and stopped at the far left of the fork in the road, at the bare rock face.

The rock face was no different from the surrounding rocks, its grayish-brown surface covered with tiny cracks, and a few clumps of unknown moss clung to it, damp and gleaming with a dark green light.

If you only look with your eyes or rely on your divine sense, you won't be able to discover anything special about this place.

"Hehe, didn't expect that, did you? You managed to guard against outsiders, but you couldn't guard against me, could you?"

She muttered to herself, her voice full of smugness.

He raised his hand and took out a palm-sized jade pendant from his sleeve.

The jade tablet was entirely blue-green, with fine array patterns engraved on its surface, and faintly shimmering with spiritual light, just like the one she usually used when setting up arrays.

Spiritual energy is infused.

The jade pendant suddenly gleamed.

Then, a faint array fluctuation emanated from the rock wall in front of them.

The fluctuation was very slight and faint; if one did not know beforehand, one would not notice it at all.

The core of the concealed formation began to slowly emerge, and spiritual patterns lit up from the depths of the rock wall, like dormant veins being awakened, spreading, intertwining, and outlining on the stone surface.

The next moment, a third intersection appeared at the fork in the road.

The opening was about three feet wide, with clean edges, as if someone had cut a crack in the rock wall with a sharp blade.

As for why she knew there was a formation here that concealed the passage?

It's very simple; she set up this formation herself.

As the last opening of this ancient cave secret realm was about to end, the Cheng and Liu families, who owned the secret realm, approached her and asked her to set up a concealment formation here.

They looked nervous and spoke evasively, but they were exceptionally generous, not even haggling over the price.

She guessed right away that the two families must have discovered something they didn't want outsiders to know.

Later, she subtly probed and managed to extract a few words from the young man in the Cheng family.

It turns out they discovered a second secret realm beneath this cave!

Beneath this cave lies a space that has never been set foot in before.

The discoverers were two younger members of the Cheng and Liu families. They found a third-tier spiritual herb on the second floor and were immediately thrilled.

However, their strength was limited, and they were simply unable to investigate completely in the limited time remaining.

After discussing it, the two decided to leave the secret realm and inform their families.

After discussing it, the two families decided not to tell the He family about it.

So they immediately asked Master Qin to set up an array to hide the entrance so that no one else could find it.

In this way, while the news of the secret realm possessing a second level isn't something everyone has exclusive access to, it's still better than having it shared among three parties, right?

This is why she knew there was a formation here.

Of course, all of the above may just be her guesses.

She didn't know if that was the case, but none of that mattered anymore!

"Hehe, spirit stones, here I come!"

Qin Yulin rubbed his hands together, then his figure flashed and disappeared into the newly appeared opening.

Her steps were as light as a child who had stolen candy, and even her back view exuded an eagerness.

As soon as she entered, the concealment formation began to return to normal.

The lit-up spiritual patterns slowly dimmed and disappeared back into the depths of the rock wall, as if they had never appeared.

The extra fork in the road, like ripples on the water, gradually receded until it disappeared completely.

The rock face returned to its original state, bare and indistinguishable from its surroundings.

……

Lin Che, who was following behind her, had a smile on his lips.

This trip to the hidden realm was indeed very interesting!

He originally came only for the time law of the secret realm, but he didn't expect to encounter such a pleasant surprise.

The divine eye and keen perception are revealed, and the attack begins.

His gaze suddenly changed.

The bare rock face was no longer a rock in his eyes, but a net woven from countless spiritual patterns.

The outline of the concealment formation began to emerge clearly.

The spiritual patterns were as fine as hair, layer upon layer, intertwined and wrapped tightly around the entire entrance.

Some patterns are responsible for concealment, erasing the existence of the entrance from sight and consciousness;

Some patterns are designed to confuse, causing people who are close by to subconsciously ignore that area;

Some of the patterns serve as barriers to prevent people from accidentally wandering in.

"I see, no wonder you are Master Qin."

Lin Che sighed in admiration.

This is a combined formation with overlapping effects of concealment, deception, and obstruction, each element of which is indispensable.

This formation is not just invisible to the naked eye.

Even if someone touches it with their hand, the texture is exactly the same as a real rock wall—rough, cold, and hard—so no one would suspect anything.

Such an ingenious arrangement would be impossible for outsiders to discover unless the person who set up the formation personally led the way.

After thinking for a moment, Lin Che decided not to break the formation.

He turned his head to look at the Azure Profound Realm Spirit.

The Azure Profound Realm Spirit following behind immediately understood.

Its entire body emanated a pale blue demonic power, and spiritual light slowly enveloped Lin Che, forming a thin, semi-transparent light membrane around him.

The next moment, the person and the beast were teleported directly into the formation.

There was no tearing of the array patterns, no triggering of alarms, and no disturbance of spiritual energy.

They simply vanished from in front of the rock wall and then reappeared out of nowhere behind it.

They completely ignored the barrier of the formation.

Lin Che stepped into the hidden passage, his footsteps making a soft rustling sound on the ground.

The passage was narrower than expected, and the rock walls on both sides were wet, with water droplets sliding down the stone walls and dripping onto the stone steps on the ground, making a crisp "drip, drip" sound that echoed in the empty passage.

The eye of the storm continues to activate.

Lin Che also discovered that there were still traces of formations in the passageways inside the cave, indicating that there were still arrangements inside.

The spiritual patterns extended along the rock walls on both sides of the passage, some leading to deeper forks in the path, some hidden in the crevices of the stone steps, and some wrapped around the stalactites on the cave ceiling.

Sure enough, after walking for a while, we encountered another place of concealment and obstruction, as well as a formation that confuses people and leads them to a fork in the road.

Those side roads may seem like main roads, but they actually lead to dead ends, and going into them will only waste your time.

Without Qin Yulin leading the way, even a Golden Core cultivator would find it difficult not to lose their way amidst the layers upon layers of array traps.

After walking for about half an hour, a downward-facing cave appeared in front of them.

The cave was not large, with an entrance diameter of only about ten feet. Its edges were smooth, as if they had been eroded by water over many years.

The cave was pitch black, and its depth was indiscernible. Only gusts of damp, earthy, cold wind rose from below, causing one's clothes to flutter.

Without hesitation, Lin Che jumped straight down.

The wind howled in my ears, and my robes fluttered in the air.

He controlled his body and slowly descended, his gaze sweeping over the cave wall.

Those rocks, layer upon layer, are like pages of a book, recording millions of years of geological changes.

Occasionally, a few luminous mosses cling to the rock face, emitting a faint green glow, like stars twinkling in the darkness.

After falling for about twenty feet, light finally appeared beneath their feet.

Suddenly, everything became clear...
