After an unknown amount of time, even the high-grade spirit stones ran out.

What appeared before him was a dense cluster of top-grade spirit stones.

For most cultivators, even those at the Deity Transformation stage, such a sight would be enough to drive them into excitement.

Xiao Shou had once been the same a few years ago.

But after seeing so much over the years, it was now difficult for him to feel excited.

He calmly continued collecting the top-grade spirit stones.

One piece, two pieces, three pieces...

Eight hundred seventy-three pieces.

This was actually a large-scale spiritual vein.

From the outside, there had been no sign of it at all.

The spiritual energy around Endless Grief Mountain showed no abnormalities.

Its density was similar to many remote wilderness areas, only about three times richer than Snowy Cave Mountain.

Without the Spirit Chaser Plate, this place would have been impossible to find.

Could there also be jade concealment stones here that blocked the spread of spiritual energy?

Or had the ancient cultivator used some method to seal the spiritual energy and preventing anyone from discovering that this was a large spiritual vein capable of supporting an entire sect?

It was most likely the latter.

After all, the surrounding rock and soil showed no properties that could block spiritual energy diffusion.

During excavation, he had already faintly sensed this.

The spiritual energy of the vein was continuously being drawn away by a gentle yet irresistible force, gathering toward a single location.

At that moment, Xiao Shou could clearly sense that location.

It was directly above his head.

He took a deep breath.

Thinking of the possible situations he might face, he consumed a drop of diluted spirit spring milk and sat cross-legged to recover his stamina and spiritual energy.

After finishing his adjustments, he carefully began cutting into the rock above.

As chunks of stone were sliced away and stored into empty storage bags, a ray of light soon shone down through a crack.

He had reached it.

Xiao Shou felt a surge of joy and became even more cautious as he cutting away the final piece of rock.

He put away the luminous stone and used his strength to leap upward from below toward the source of the light.

After reaching the top, Xiao Shou froze.

It was not the dense spiritual energy here that stunned him.

After all, the spiritual energy at Snowy Cave Mountain was far richer than this.

What shocked him was something that should not exist here.

All around him was an extremely vast stone chamber, it was so large that its exact size was impossible to estimate.

Above the chamber hung an object radiating intense and brilliant heat, like a miniature sun.

It resembled something described in the book Longevity Love, a Blazing Sun Stone that no longer existed in the Heaven Origin Realm and could only be found among major powers in the Spirit Realm.

It was said to be cut from a dying sun.

For now, he would call it a Blazing Sun Stone.

Beneath the Blazing Sun Stone, about a hundred meters away from Xiao Shou on the ground, stood a ten meter tall transparent stone pillar.

Inside the pillar, a palm sized mass of silver gray liquid floated motionlessly at its center.

From this liquid extended countless threads even finer than hair, spreading toward both ends of the pillar.

From the base of the pillar up to the position of the liquid, intricate and mysterious patterns were carved into it.

They looked like runes, yet also like formation patterns.

At the center of these patterns, about one meter above the ground was a symbol Xiao Shou could recognize. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

It was the Big Dipper constellation.

At the positions of the seven stars, seven top-grade spirit stones were embedded, each radiating brilliant spiritual light and clearly filled with energy.

At the very center of the seven stars, there was a palm imprint.

The appearance of this pillar strongly resembled something described in the book.

A Celestial Nail.

Once installed, it could allow massive structures such as palaces, spirit mountains, or blessed realms to teleport, float, and even fly.

In the story, the Celestial Nail first appeared in the Spirit Realm, when the female lead obtained one and refined it into her first flying vessel capable of flight and levitation.

According to the description in the book, a Celestial Nail was a method that could only be used by powerful cultivators with a magnetic spiritual root.

They would extract the true magnetic force from super-gravity stars and refine it with teleportation formations engraved into it.

Once activated, as long as there was sufficient spiritual energy supply, the true magnetic force at the center of the pillar could extend countless magnetic threads outward.

Under the user’s control, it could increase or decrease gravity and adjust gravitational force.

Within a certain range, it could enable teleportation, levitation, and flight.

In theory, as long as there were enough spirit stones, it could operate endlessly, though there was still a cooldown period.

The area it could control depended on how much true magnetic force was extracted during refinement and how intricate the engraved formation patterns were.

In short, the smallest Celestial Nail could control a cave residence of about one hundred square meters, while the largest could even suspend an entire massive immortal mountain.

Of course, the largest type was something only seen in the Immortal Realm.

In the Spirit Realm, most were used for small cave residences or flying vessels, and rarer ones for palaces.

In the Heaven Origin Realm, however, flying vessels and mobile cave residences mostly relied on formations that generated wind force or gravity as propulsion.

For example, the flying wooden crane puppet Xiao Shou often used.

The application of Celestial Nails was something that only came into play after reaching the Spirit Realm and even there, not many people could afford to use them.

Yet one had appeared here.

Could it be that this ancient cultivator’s cave residence was actually a mobile structure capable of teleportation, flight, and levitation?
