Immortal cultivation starts with copying.

The treasure-hunting rat has followed Chen Yunhao for many years, even though Chen Yunhao has invested a lot of resources in it.

However, it is very difficult for innate spiritual creatures like the Treasure-Seeking Rat to advance to the next level, and it is still stuck at the Mahayana cultivation level.

This level of cultivation was neither high nor low, and it didn't help Chen Yunhao much, so he used it less in recent years.

Chen Yunhao felt that the treasures below the valley were not of high level and therefore did not pay much attention to them, which is why he sent the treasure-hunting rat down to take a look.

Seeing the treasure-hunting rat fly down, Chen Yunhao continued to study the jade slip in his hand.

In about half an incense stick's time, the treasure-hunting rat flew up.

"Master, there's nothing down there, just some unremarkable medicinal herbs...!"

Chen Yunhao was stunned when he heard this.

With the Treasure-Hunting Rat's abilities, it can easily sense and find treasures even if they are hidden several feet underground.

The glow he saw twice was definitely real, unless that treasure could grow legs and run away on its own.

But if that treasure really could escape on its own, how could Chen Yunhao not sense it? Therefore, the treasure must still be below.

The fact that they could fool the treasure-hunting rat immediately piqued Chen Yunhao's interest.

He put away the jade slip, leaped down, and landed in the valley a moment later.

He remembered the place where the glowing light was, not far from his feet.

Now all I see is grass, very dense grass.

His divine sense revealed everything, even the ground several feet below the grass.

Apart from some underground insects and ants, there was truly nothing there.

"That's interesting...!"

Chen Yunhao smiled slightly and simply sat down at the foot of the valley, waiting quietly.

The rosy dawn never appeared, but the clouds and mist in the valley grew thicker and thicker, blocking out the sun and preventing it from shining down.

The valley remained calm all day, and the glow of dawn did not appear.

Even mosquitoes, rats, and low-level monsters did not appear, because of Chen Yunhao's presence. The aura and pressure of an immortal kept those low-level creatures away.

Throughout the day, Chen Yunhao held the Dragon Sky Stone in his hand, studying it carefully.

He had read about Dragon Sky Stone in ancient books; it could only be born in places where dragons lived.

Because dragons are born with spatial abilities, things like flying through the clouds are child's play for them.

As for refining the Dragon Sky Stone into a celestial artifact, Chen Yunhao never considered it.

Because he himself is neither capable of forging immortal artifacts nor has the need to.

The Dragon Sky Stone is covered with tiny holes, like anthills.

A gentle breeze blows across the Dragon Sky Stone, causing ripples to appear on the hollow holes.

This is the fluctuation of space, and it is an ever-changing fluctuation.

"Indeed mysterious...!"

The laws of space are vast and profound, with countless mysteries. Even a cultivator who becomes an immortal may not reach the point of mastery in their entire life.

A single Great Dao contains three thousand Lesser Daos. To comprehend even one of these Lesser Daos is no easy feat; it may take thousands or even tens of thousands of years.

Knowing his own situation, Chen Yunhao had only comprehended six or seven minor spatial paths since he began studying the Great Dao of Space.

This also increased his strength by more than double, and the Dragon Sky Stone has at least thousands of holes, which manifest hundreds of spatial fluctuations.

Once he can fully comprehend these hundreds of techniques, his strength will be on a completely different level.

However, this is also a difficult task. To be able to comprehend these hundreds of minor spatial paths within ten thousand years would already make one a top genius.

Night fell quickly, and the moon rose high in the sky once more.

Chen Yunhao put away the jade slip in his hand, looked up at the sky, and saw that the clouds above had dispersed quite a bit due to the moonlight.

The moonlight shone down, and Chen Yunhao released his divine sense, staring at the place where the sunset glow had shimmered the night before.

As time passed, an hour later, another ray of light flashed before his eyes.

This time he saw it clearly: when the ray of moonlight shone on a certain spot at the bottom of the valley, it disappeared in mid-air.

It was as if a ray of moonlight had been intercepted, and right there, a glow of dawn appeared.

"A hidden space?"

A guess flashed through Chen Yunhao's mind: if it wasn't a hidden space, the moonlight wouldn't have disappeared into thin air.

Chen Yunhao hadn't sensed any spatial fluctuations just now, but the radiant light had indeed pierced through from another space.

Chen Yunhao remained standing still, waiting for the next ray of moonlight to shine on him.

Based on observations last night and today, the glow of the sunset can only be revealed when the moonlight shines at a certain angle.

As the moonlight moved, it was already late at night. Another ray of moonlight slanted down, and the glow of the sunset flashed by in an instant.

This time, Chen Yunhao was absolutely certain that a small space existed here.

Only when the moonlight reaches a certain angle will a small hole be revealed.

That rosy glow must be a treasure within that small space; there's no doubt about it.

Having encountered such an opportunity, Chen Yunhao certainly wouldn't leave easily.

The first priority is to find the entrance to that space. We can force our way through that small hole that was just revealed.

However, Chen Yunhao didn't know whether this small space was stable or not. If it was unstable, forcibly breaking it open would result in the collapse of the entire space.

The consequence is that all the treasures inside will fall into the spatial storm and will have nothing to do with him anymore.

Every small, man-made space, like a house, will have a door, unless it's naturally formed, in which case it's hard to say.

With a swift movement, Chen Yunhao floated around the entire valley, setting up two immortal arrays.

He has two or three sets of this kind of portable immortal array, all of which he bought at a high price. Even if a celestial being came, they wouldn't be able to break it in a short time.

One is a defensive immortal array, and the other is an isolation immortal array.

With the immortal array in place, Chen Yunhao was no longer afraid of the fluctuations here spreading out.

Chen Yunhao moved rapidly back and forth more than ten times around the space where the rosy light was revealed.

His hands never stopped, tapping left and right, creating spatial ripples that spread around him like waves on the surface of water.

After a short while, Chen Yunhao stopped again, his expression no longer relaxed but rather somewhat solemn.

Despite his mastery of spatial laws and techniques, he was unable to pinpoint the location of the entrance to that space.

"How strange...!"

Chen Yunhao muttered to himself, wondering if his mastery of spatial abilities was insufficient, or if the space was simply too deeply hidden.

Unwilling to give up, Chen Yunhao tried again, but still to no avail.

He wanted to ask the spirit of the artifact to help him, but he was unwilling to do so. He couldn't just turn to the spirit of the artifact every time he encountered a problem. How could he ever truly grow up if he did that?
