I established the Eternal Immortal Clan by taming beasts.

When Lin Che arrived at the base entrance, Qin Yulin was squatting in front of the rock wall covered with vines.

The magic pen in her hand moved slowly across the stone surface, precisely outlining something along an almost invisible arc.

Her movements were slow, yet she was extremely focused. Each stroke required a pause, as if she were waiting for some kind of feedback, waiting for the silent wall to respond to her probing in its own way.

The array masters behind them also squatted on the ground in the same posture, each in charge of a section, recording the deconstructed patterns one by one into the spiritual light diagram. The fine rustling sound made when the pen tip touched the stone surface was particularly clear in the quiet valley.

As soon as Lin Che arrived, his personal guards and Lin Xinqing and the others were about to bow when Lin Che waved his hand to indicate that it was not necessary, and looked at Qin Yulin and the other two.

"How is it?"

"It hasn't broken through yet." Qin Yulin didn't look up, but just tilted his head slightly as a response to Lin Che's arrival.

Her magic pen paused for a moment on the stone surface, then continued moving forward along the arc.

"However, we've already figured out the pattern. This rune structure isn't for reinforcement; it's for locking. To be precise, it's waiting for a specific spiritual energy frequency to trigger it. Only someone carrying that specific spiritual energy frequency can activate it on their own. I reckon you'll have to come in person."

She also had some knowledge of the secrets of the Southern Region, and the events that had occurred recently had deepened her understanding of the Lin family, so she could naturally guess what kind of cultivation method the Lin family practiced.

Although she didn't care where this place was, and she was only here to study the formation, Xiao Qingqing didn't hide anything from her at all.

Lin Xuanqing told her about everything from the initial purpose of coming to this base to the history of the Ten Thousand Beasts Sect, intermittently along the way.

So after several hours of research, the two of them arrived at the same conclusion.

Besides concealment, the most important function of the formation here is to seal things away, waiting for the arrival of the successor.

Without hesitation, Lin Che walked to the rock wall.

In fact, Lin Che had inquired about this cultivation base during his second conversation with Venerable Bai Ze several days earlier.

According to the leader of the Azure Scale Wind-Patrolling Beasts, this breeding base was deliberately sealed off by the Myriad Beasts Sect. Besides not leaving it to the Great Qian Dynasty, it must have served another purpose—to preserve its legacy!

Venerable Bai Ze also proved this point. Not only this one, but several training bases were actually sealed off before the Ten Thousand Beasts Sect was destroyed, in order to leave the Ten Thousand Beasts Sect's inheritors with the foundation to rise again.

Since that's the case... Lin Che sensed the formation on the rock wall, raised his right hand, placed his palm on the rock wall, and began to slowly activate the Myriad Beasts Technique.

Although Lin Che practiced the Ten Thousand Beasts Paying Homage to the Ancestor Technique, which was a superior alternative, the Ten Thousand Beasts Technique, which served as the foundation, was much simpler to learn and shared the same origin, so he was naturally familiar with it.

Pale blue spiritual energy began to flow slowly, seeping into the rock wall along the lines of his palm, like a stream flowing into a dried-up riverbed, finding its way again along paths worn smooth by time.

The formation showed no sign of rejection; the patterns carved deep into the rock wall responded at the same frequency.

A moment later, the patterns on the rock face covered by vines began to light up from the depths. First, a very light silver-gray light appeared, then it lit up one by one along the nodes marked by Qin Yulin, spreading outwards and re-outlining the contours of the entire rock face in the spiritual light.

The rock face that was once disguised as an ordinary rock is now peeling away its disguise layer by layer, revealing its original texture underneath.

The fine cracks on the rock face began to slowly extend and merge along their lines, like a riverbed being re-injected with new water finding its original path.

Within moments, the entire rock face became as transparent as ice, like a huge, polished crystal, refracting a warm, silvery-blue light in the morning sun.

Through the gradually transparent rock wall, the outline of the interior can be vaguely seen.

The internal passageways, stone steps, and porches—structures covered by time and dust—are slowly emerging from the darkness.

"It's done." Qin Yulin stood up, dusted off his hands, and a barely concealed smile appeared on his face. "Hehe, I told you I could do it! Come on in and take a look!"

Lin Che didn't bother to complain that this breakthrough had nothing to do with her, and stepped across the fading light barrier.

Beneath my feet was a stone staircase leading downwards, its surface covered with a thin layer of grayish-white dust. The dust rose slightly the moment my toes touched it, carrying the fine texture unique to millennia of sedimentation, drifting in the air before slowly falling back to the ground.

On the walls on both sides, at intervals, there is a spirit ore that is slowly glowing.

The light of the spirit ore had been weakened by time, leaving only a barely visible amber halo, like dusk, which enveloped the passage in a dim yet warm light.

Lin Che's gaze swept around, and he frowned slightly. He felt a sense of familiarity.

"You all stay outside, I'll go in and scout ahead by myself."

That's what they say, but even though Lin Che has already reached the Nascent Soul stage, he is still cautious and naturally won't rush in.

Just before arriving here, he had the Azure Profound Realm Spirit leave a coordinate so that he could be teleported away immediately if danger arose.

At the same time, Lin Che left Ya Zi outside. If anything unexpected happened, Ya Zi's strength would be enough to protect Xuan Qing and the others, and Lin Che would be able to detect the situation here immediately.

After arranging everything, Lin Che walked down the stone steps for about the time it takes to brew a cup of tea, and finally reached the end of the passage.

At the end of the passage was a sealed stone door, with a pattern carved on its surface that had become mostly blurred.

The outline of the pattern has been worn away by time, but its general shape can still be discerned.

Nine different mythical beasts, each with a unique form, are linked together, forming a circle. In the center is a silhouette of a person and a beast standing side by side. The person seems to be holding a long staff whose shape is indistinct.

According to Lin Che's understanding of the history of the Ten Thousand Beasts Sect, this is precisely the emblem of the Ten Thousand Beasts Sect.

Feeling the increasingly familiar energy fluctuations, Lin Che placed his palm on the center of the door and slowly activated the Myriad Beasts Technique.

Pale blue spiritual energy surged from his palm into the patterns on the stone gate, slowly spreading outwards along the grooves eroded by time, like re-injecting living water into a dried-up riverbed.

Without feeling any resistance, the door slid silently inward under his palm.

A pale purple spatial rift floated silently in the center of the door frame, like a frozen surface of water, its surface shimmering with fine silver patterns. Each flicker distorted, folded, and rearranged the surrounding light.

That familiar spatial fluctuation was slowly seeping out from the depths of that rift.

"So, this really is a secret realm?"

Having traversed the Azure Mystic Realm for many years, Lin Che was already familiar with its energy fluctuations.

It was a special texture, like the slight sense of dislocation you get when looking at something through water. Lin Che noticed this unusual feeling as soon as he stepped into the passage.

"That makes sense. The Ten Thousand Beasts Sect was so large back then, how could its spirit beast breeding base be simply built on a spiritual vein? Choosing to build it in a secluded secret realm would have been the best option, which also explains why the breeding base wasn't located within the sect."

These secret realms are mostly formed naturally, spatial folds that appear by chance in the world. Their locations are naturally not fixed, which is why they appear in places like the middle section of the Fulong Mountains, far from the core area of ​​the sect.

With this in mind, Lin Che released the Azure Profound Realm Spirit.

"Xiao Xuan, check the stability of this secret realm." Qingxuan Realm Spirit was the expert in this area, and Lin Che only dared to enter after confirming that there were no problems.

Having learned the whole story, the Azure Profound Realm Spirit's eyes lit up with a pale blue light as it began to sense this isolated secret realm.

After a moment, the Azure Profound Realm Spirit nodded, the blue light in its eyes slowly receding: "No problem, the space is very stable, and its rank is very high."

"Okay, I plan to go in and take a look. Be ready at any time, and teleport out immediately if any danger arises." Lin Che said, stepping towards the spatial rift.

The Azure Profound Realm Spirit nodded, floating behind Lin Che, its spatial power flowing within its body, ready to teleport at any moment.

The scene before Lin Che shifted, as if covered and peeled away by a flowing curtain of water, with light being shattered and reassembled in that instant.

The next moment, a bright light enveloped Lin Che.

As far as the eye can see, there is an endless grassland.

The lush green grass stretched to the horizon, with no obstructions between it and the sky.

The grassland is dotted with patches of spiritual plants, some as low as a carpet, others as tall as a person's waist, like emerald pearls scattered at random.

In the distance, low hills rise and fall, casting long shadows across the grassland. The outlines of those hills are soft and long, like a sleeping giant breathing slowly.

The sky was a color between pale blue and moon white, as clear as water that had been filtered repeatedly. The sun was not visible, but a uniform and warm light shone down from the dome, illuminating the entire space.

The air was filled with the fresh scent of grass and flowers, a fragrance that was crisp and vibrant, as if every breath was awakening the essence that had been sealed away by time.

The most crucial element is spiritual energy!

The rich spiritual energy invigorated Lin Che, like taking the first breath of fresh air after emerging from murky water.

These spiritual energies were flowing into his meridians in an almost proactive way, without the need for cultivation techniques or deliberate guidance; they were searching for channels to enter on their own.

The spiritual energy flowed slowly through his meridians. Without any conscious effort, it found its own direction and distributed to his limbs and bones along the repeatedly refined spiritual paths.

Lin Che turned his head and exchanged a glance with Qingxuan Realm Spirit; both of them showed a look of surprise in their eyes.

Without a doubt, the spiritual veins inside this secret realm have reached the fifth level, even higher than those in the Azure Profound Secret Realm!

After Lin Che broke through to the Nascent Soul stage, the fourth-tier Azure Profound Secret Realm was no longer sufficient for him to continue breaking through. Searching for higher-tier secret realms was something they had been doing all along, in order to replicate and upgrade the Azure Profound Secret Realm.

But to their utter surprise, they ran into each other here.

"Don't rush into anything." Lin Che withdrew his gaze, suppressing the surging joy in his heart. "Let's explore this secret realm first and see what else is left inside."

Walk along a path covered in grass.

The feel underfoot is slightly different from that of ordinary grasslands. Underneath the turf is not soft soil, but a more solid base layer with traces of artificial leveling, like a roadbed that has been repeatedly compacted and has maintained its original flatness for thousands of years.

After walking for about the time it takes for an incense stick to burn, a row of low-rise building silhouettes appeared ahead.

The roofs of these buildings have mostly collapsed, and the remaining walls are covered with vines and moss, revealing a grayish-brown color that has been soaked in time in the sunlight, forming a stark contrast with the surrounding greenery.

Even so, the main structure of those buildings still retains a recognizable shape.

It was a row of standard spirit beast sheds, with feeding troughs and watering wells in front of each shed. The wells had been mostly filled with soil and fallen leaves, but their outlines were still clearly discernible.

Lin Che stopped in front of a relatively intact shed and waved away the vines covering the entrance.

The space inside the shed was larger than expected. The ground was paved with smooth stone slabs, and in the corner there was a pile of weathered spiritual herbs, which had been compressed into a thin layer of brownish-gray sediment over time.

Unfortunately, there was still no sign of life here. Leaving the shed, Lin Che continued walking forward.

The deeper you go into the grassland, the higher the density of those building ruins becomes, gradually transforming from scattered shacks into clusters of buildings.

There were larger sheds, warehouses, a building that resembled a clinic, and a circular building that was completely covered by plants.

The base of this building, whose purpose is unknown, is made of bluestone. Thick vines grow from the cracks in the bluestone, wrapping the entire building in a green ridge. These vines meander and climb on the stone surface, like veins magnified by time, as if they are taking over this forgotten structure.

The grassland begins to become uneven at the end of the building complex, gradually rising to form a gently sloping hillside.

On the slope grows a type of shrub that is taller than those in other parts of the grassland. The edges of the leaves of these shrubs shimmer with a very faint silvery-white light. With each breeze, the leaves refract tiny specks of light as the angle of the light changes.

At the top of the gentle slope is a courtyard surrounded by stone walls. Most of the walls have collapsed, but a stone gatepost still stands at the main entrance.

The gateposts are engraved with the same emblem of the Myriad Beasts Sect as those at the entrance.

Compared to the worn-out pattern at the entrance, the emblems here are much better preserved, with each head maintaining its own posture—some raised, some lowered, some with outstretched wings, and some perched—each with a different form.

Lin Che and Qingxuan Realm Spirit exchanged a glance, then walked together towards the courtyard at the top of the slope...
