I established the Eternal Immortal Clan by taming beasts.

The war beast in the relief let out a low roar the moment the red light passed by.

The vibrations caused a layer of dust on the surface of the stone gate to rise, which was then smoothed out by the subsequent light.

Finally, Chi Lin stepped forward and embedded the last token into the central arc-shaped groove.

As the moon-white light rose from the surface of the token, it came into contact with the blue and red light at the same time.

At the point of intersection, the three colors each maintain their own boundaries in their own way, without penetrating or repelling each other, but coexisting in a parallel manner, forming a light trail with the three colors arranged in parallel at the point of intersection.

The reliefs of sacred plants on the stone gate began to change under the moonlight.

The flower buds, which were originally fixed in stone form, bloomed one after another.

Each flower slowly goes from closed to half-open to fully open, and then the petals curl inward from the edges, dry up, and wither. After withering, it grows, blooms, and withers again at the same speed.

This process was repeated three times, and each time a fainter mark was left on the flower bud than on the surrounding area.

After completing their respective journeys, the three beams of light converged simultaneously towards the silhouette of a person and a beast in the center of the stone gate.

The three rays of light—cyan, crimson, and moon white—converged, merged, and rotated at the silhouette, eventually condensing into a continuously flowing light symbol.

The radiant light lingered in the center of the stone gate for about three breaths before sinking into the interior of the stone gate as if it had been sucked into the water.

The stone gate slowly opened to both sides.

The light leaking through the crack in the door was brighter than the light from the spirit ore on both sides of the stone steps, spreading out a continuous golden band of light along the edge of the stone door.

Behind the door was a huge underground space.

High above the dome, a star pattern made of spirit stones lit up one by one in the twilight, and a dark blue light formed a slowly flowing star map above the dome.

Hundreds of large bookshelves and display stands lined both sides of the hall, with jade slips and scrolls neatly stacked on them, sealed within an array.

In the center of the hall was a passageway about three zhang wide, at the end of which was a lower doorway, half-hidden behind a layer of pale golden spiritual light curtain.

Chi Lin stood inside the stone gate, his gaze sweeping over the dense bookshelves and display stands on both sides of the hall. A faint smile appeared on his lips: "It seems that the relics on the first floor are more abundant than we expected."

Bi Yu didn't reply. Her gaze fell on the top of the tallest bookshelf in the center of the hall, where a scroll tied with dark silk thread was placed. A faint spiritual light emanated from the edge of the scroll, flickering in the shadows at the top of the bookshelf.

Lin Che's gaze didn't linger on the bookshelves and display stands for long. He merely scanned their overall layout, confirming the direction of the passageways and the location of the doorway at the end of each passageway before turning his attention away. "Lord Chilin needs bloodline secret techniques, while our two families need other things. How about we part ways here temporarily and each go to find our own goals?"

"Alright, it's settled then!" Chi Lin didn't ask any more questions and turned around to direct the others to disperse to the bookshelf area on the left.

The four figures dressed in dark red robes moved in two groups in different directions. One group moved quickly along the aisle between the bookshelves, while the other group stopped in front of the bookshelves near the entrance and began to check the labels and classifications of the jade slips row by row.

"We're fine here too." Bi Yu turned around and whispered something to the Qingluan clan members behind her, her voice extremely low.

The Azure Phoenix Clan member nodded and began to move among the bookshelves, his steps lighter than those of the Crimson Serpent Clan, ensuring that each movement did not disturb the dust on the edges of the bookshelves.

Lin Che and his group walked through the hall and headed towards the doorway half-hidden behind a curtain of golden spiritual light. "First, confirm the location of the Heart of Return to Nothingness." His voice was not loud, maintaining a volume that only the two people beside him could hear in the empty hall. "We don't lack these inheritances."

According to Venerable Bai Ze's information, the most important thing in this secret realm is called the Myriad Beast Source Core, which is the Lin family's primary goal for this trip.

To say that the Lin family doesn't need this tradition is certainly not true.

However, when they first embarked on the path of beast taming, the Lin family already possessed the core cultivation techniques and complete training manual of the Ten Thousand Beasts Sect. Furthermore, through system upgrades, it can be said that the Lin family has almost no missing core inheritances in this regard, so there is no point in competing with the other two families here.

It would be better to get the Beast Core as soon as possible.

The group dispersed behind him, and Lin Che and his party headed towards the cave entrance.

As Lin Che approached, the light on the surface of the doorway, which was half-hidden behind a curtain of golden spiritual light, slowly receded to both sides, like water rippling in the wind, revealing a passageway completely different from the main hall.

The passageway was narrower than the previous one, barely wide enough for two people to walk side by side.

The stone walls on both sides were no longer inlaid with spirit ore; instead, they were covered with a bluish-gray stone that shimmered with light.

Light shines through the stone, as if moonlight has been crushed and kneaded into the texture of the rock, creating a continuous and even illumination in the dim space.

The passage is about a hundred zhang long, extending downwards in the form of a gentle slope. Every so often there is a slight turn, making the entire passage present a gentle curve rather than a straight line.

When the passage finally came to an end, the space in front of us suddenly opened up.

The dome was not made of spirit stones, but a real cloud layer formed by the condensation of spiritual energy. The clouds churned beneath the dome at an extremely slow speed, with a faint golden light shining through their edges as if they were being bathed in sunlight.

It was early morning in the simulated sky, and pale golden light seeped down from the edges of the clouds, spreading a diluted warm halo over the land below.

Below is a complete ecological space that operates based on the spiritual veins.

"This space is not a secret realm, but a simulation created by an array." Lin Xuanqing's voice carried a suppressed vibration the moment he spoke.

The outline of the hills stretches from near to far, covered with patches of tall grass and shrubs. The colors of the vegetation present alternating shades of green in the morning light, with each layer maintaining a smooth transition.

Further away, a stream meanders down from the top of the hill. As the stream flows through the meadow, it reflects tiny specks of light in the sunlight and then gathers into a vast, shallow lake in the low-lying area of ​​the valley.

The air was filled with the scent of grass and trees that had been repeatedly permeated, mixed with the faint fragrance of moisture and spiritual plants, making each breath deeper than the last.

Most striking of all are the large herds of beasts moving across the distant slope; there are more than a dozen herds of spirit beasts, each exceeding a hundred individuals, right at this entrance alone…

"This space simulated by the same array... is more complete than I imagined." Lin Xuanqing's voice was very soft. Her gaze lingered on the distant herd of beasts for a moment, then slowly moved between the nearby stream and shallow lake.

"The spiritual energy concentration here is about level five. Indeed, you can feel that the direction of the flow is regular. It is not a uniform distribution. It is more like the entire space is completing the circulation of spiritual energy along a certain fixed path."

The Fiery Sky Sacred Sparrow's keen gaze fell on the distant hills. Its shoulders tensed slightly for a moment before relaxing: "Something is observing us. It's not a herd of beasts, but some kind of solitary entity watching from a fixed position high up. It's not hostile, but it doesn't intend to approach either."

Lin Che followed her gaze.

At the top of the hill is a protrusion made of dark gray rock, which appears in a different hue from the surrounding vegetation in the morning light. The protrusion is located at the edge of the animal herd's movement path, so that it can be observed by the observer without being disturbed by the movement of the animals.

He didn't linger on the protrusion for long, only confirming its location before looking away: "First, confirm the location of the Myriad Beast Source Core. Venerable Bai Ze mentioned that the location of the Source Core can be deduced from the direction of the spiritual energy flow throughout the entire space. If the spiritual energy circulation here operates around the Source Core, then following the direction of the spiritual energy flow should lead us to the core area."

Lin Xuanqing took out a completely transparent jade slip from his sleeve, held it in his palm, and gently ran his fingertip along the edge of the jade slip. A very faint blue halo appeared on the surface of the jade slip.

The halo began to deflect slightly in a certain direction the moment it came into contact with the surrounding air. The movement was slow, but it remained continuous and uniform.

She adjusted the angle of the jade slip, and after confirming that the direction of the deflection was stable, she raised her head: "The overall direction of the spiritual energy flow is southwest, tilting downwards at an angle of about twenty degrees. The source core should be located over there." She raised her hand in the southwest direction, her fingertips pointing to the low-lying area between the hills, where there was a valley covered with tall grass, which appeared a deeper green than the surrounding area in the morning light.

The three members of the Lin family began to travel in the direction indicated by the spirit-testing jade slip.

The meadow beneath your feet changes with the undulations of the terrain. In some places, the grass blades are above your ankles, while in others, the ground is covered with fine gravel, which makes a finer, more subtle friction sound when you step on it.

After noticing their movement, the herd of animals in the distance began to adjust their course, changing from moving laterally to spreading out to both sides, making way for the group that was crossing the meadow.

The second level is quite large, and Lin Che and his group haven't explored it thoroughly yet. Finding the entrance to the third level is the most important thing right now.

After traveling about three hundred miles, the valley covered with tall grass appeared not far ahead.

The valley's outline slopes gently downwards, with the deepest part of the ground covered by a denser layer of vegetation than the surrounding area. In the morning light, the vegetation takes on a slightly darker green color, different from its surroundings.

As the spirit-testing jade slip approached the edge of the valley, the pale blue halo began to deflect in the same direction at a faster rate, about one-third faster than it had been on the meadow.

Lin Che stopped at the edge of the valley.

His divine sense slowly descended along the contours of the valley, passing through the dense vegetation and soft soil, until it reached a space deep in the valley surrounded by a stone structure.

The outline of the stone structure presented a regular geometric shape, with its edges made of smooth stone. In the perception of divine sense, it resembled a square box embedded in the ground.

The surface of the stone structure was engraved with a layer of fine array patterns. Those patterns lit up slightly the moment they came into contact with divine sense, and then quickly returned to their standby dark color, as if they were waiting for some specific trigger.

"This stone chamber below should be the third level, the Heart of Return to Nothingness. The Origin Core of Ten Thousand Beasts should be inside." He withdrew his divine sense and looked at Lin Xuanqing. "Can you discern the types of those array patterns?"

Lin Xuanqing didn't say anything, but took a few steps forward and squatted down on a slightly protruding rock at the edge of the valley.

Her gaze moved down the slope of the valley, her fingers slowly calculating something at her side, as if comparing the direction of the array patterns perceived by her divine sense with a framework in her memory.

After a moment, she withdrew her gaze: "The array pattern is in the style of the mid-stage of the Myriad Beasts Sect. It is based on the source core sealing array as the basic framework, but there is an outer layer of node array. It should be the entrance to a passage to a deeper level. The source core should be right below this stone chamber, sealed by the stone platform in the middle."

"In other words, to obtain the source core, we must first break this sealing array." The Burning Heaven Sacred Sparrow stood at the edge of the valley, hands on its hips, looking down at the depression covered with grass and trees below.

"Now that we know its location, it's just a matter of time before we decide what to do next. Should we start now, or should we first check the surrounding environment to ensure that the decryption process won't be interfered with?" She turned her head to look at Lin Che, the edge of the red feather hairpin on her hair flashing a brief warm reflection in the morning light.

Lin Che stood at the edge of the valley for a moment, his gaze slowly sweeping over the outline of the hills surrounding the valley, confirming that there were no approaching beasts or unusual fluctuations in aura: "From now on, Xuanqing, decipher the array patterns, Que'er, keep watch around, and Yazi, guard the entrance to the valley."

As soon as he finished speaking, Lin Xuanqing stood up and walked down the slope of the valley. He was more cautious than when he walked on flat ground, and he would check whether there was a trap before each step.

She squatted down in a depression covered by vegetation at the bottom of the valley, placed the spirit pen and several carved jade pieces beside her, and then took out a spirit-testing array plate with fine patterns carved in dark red spirit ink and placed it on her knees. She began to check the array patterns on the surface of the stone chamber one by one.

The Burning Sky Sacred Sparrow did not follow them down to the bottom of the valley. Instead, it found a spot with a wide view at the highest point of the valley and stood there, its eyes scanning the outline of the surrounding hills and the areas where the beasts were active at a steady pace.

Her gaze lingered briefly at every possible hiding place for an observer, then, after confirming there was nothing amiss, moved on to the next location with the same rhythm.

Yazi stopped behind a slightly protruding rock at the entrance of the valley, his back against the stone surface, his eyes lowered, like an old stone statue resting.

However, his divine sense had already locked on firmly, and he would know immediately if anyone approached. His divine sense spread outwards at an extremely low frequency, maintaining a rhythm consistent with the spiritual energy fluctuations in the surrounding environment, and was not detected by any passing beasts.

Lin Che stood at the edge of the valley, shifting his gaze from Lin Xuanqing, who was deciphering the array patterns, to the distant horizon covered with alternating hills and meadows, recalling the words of Venerable Bai Ze.

"The Origin Core of Ten Thousand Beasts is the core treasure of my Ten Thousand Beasts Sect. Its holder can sense the emotions and locations of all spirit beasts within a thousand miles, and perceive the flow and state of the bloodlines of all spirit beasts in the world."

Of course, the strongest is the Resonance Mark. The holder can establish a 'Resonance Contract' with any spirit beast, preventing it from harming the holder. With this item, the Lin family will truly have the possibility of controlling the demon race of the Southern Region.
