After the secondary occupation reached the maximum level, I wore it

The stone lump was soaked in the killing spring water. The hard outer shell that had just been carved by the scimitar without any trace gradually melted away, and the outer layer of toad-skin-like granular surface was corroded away as impurities, turning into black mist and floating out of the water.

But this process only lasted for a short while before the black fog stopped floating out.

"No movement?"

Shi Yu lowered his head to look, and saw that the thin layer of rough particles on the stone had been worn away, leaving behind a round, smooth stone that sparkled with a sharp green light.

The color of this stone is very beautiful, the green is pure, bright and rich, with fine lines on the surface, as if it is an ancient and warm jade.

It is beautiful, but it also makes people feel an invisible sense of oppression.

When Shi Yu cast his gaze on it, he felt as if his gaze was being sucked into it and could not be moved away, as if his soul was about to be sucked into it.

This was not an illusion. A dull pain and drowsiness came from his mind, and the feeling of his soul being pulled became clearer and clearer, as if it was being pulled out of his body. Shi Yu was startled and bit his tongue tightly. Under the stimulation of pain, he reluctantly looked away, and the pulling feeling disappeared.

Suddenly, Shi Yu felt relieved and cold sweat broke out on his back: "What is this?"

She knew that if she hadn't reacted quickly, she would have died on the spot.

The Metaverse has the same worldview as the game "Xianyuan" that she plays. In "Xianyuan", Shi Yu is a top-level secondary professional player and has handled countless rare treasures. It is no exaggeration to say that she is a know-it-all on rare treasures.

But the world is so big that it is difficult to fully experience it in a lifetime. There are still many rare treasures and mysterious magical objects that Shi Yu has never seen or heard of.

For example, this thing in front of you...

The feeling of surprise of walking on the line between life and death just now still lingered. Shi Yu did not dare to look any longer. He only reviewed the glimpse he had just had in his mind, searching his memory, trying to recall whether he had seen anything similar before.

"I have never seen anything like this with my own eyes." She thought firmly, quite confident in her memory.

So have you heard of it?

She tried hard to recall the strange stories, legends and anecdotes she had read in "Xianyuan".

Finally, a corner of his memory was dug out, and Shi Yu slowly opened his eyes.

She frowned slightly and murmured, "Could it be... the Blue Flame Dragon Sand?"

In "Xianyuan", Shi Yu obtained an ancient atlas called "Atlas of Secret Treasures of Heaven and Earth", which specifically records those lost ancient treasures that were created by heaven and earth and are unknown to the world.

She recalled the description of "Green Flame Dragon Sand" that she had read above.

"There is an object hidden in the center of the earth, green as jade. It was forged in magma and refined through thousands of hammers and refinements. After ten thousand years of not seeing human affairs, the soul was shocked to realize that it knew something. It is not easy to obtain this object, and one must die nine times before obtaining it. Those who obtain it can understand the universe, and its mysteries are endless and difficult to understand..."

In the "Illustrated Guide to Secret Treasures of Heaven and Earth", there are only a few records about the Blue Flame Dragon Sand.

It basically means that this is a magical treasure from heaven and earth that took thousands of years to be born in the center of the earth. If people can use it, they can understand the mysteries of heaven and earth and increase their wisdom and well-being.

However, this thing is very dangerous. If one's heart is not right and is greedy for its beauty, he will lose his reason, his soul will be scattered and he will not have a good end.

“Therefore, few people know about this thing, and few people seek it.”

There is a simple illustration below the text description.

Recalling the illustration and comparing it with the appearance of the stone I just saw, the stone now soaked in the killing spring water should be the Qingyan Dragon Sand.

What's more, the feeling of the soul being involved cannot be faked.

Shi Yu didn't dare to look at the body of the Green Flame Dragon Sand anymore and just stared at the water surface in the bucket.

When ordinary spiritual materials are soaked in the killing spring water, many impurities can be refined. But when the Green Flame Dragon Sand is soaked in it, only the outer shell is melted away as an impurity at the beginning, and then there is no movement.

Shi Yu understood: "After being tempered by the earth's core fire for thousands of years, there are no impurities left."

She was about to pour the water into another bucket and take out the Green Flame Dragon Sand, but she heard a few "crackling" sounds and the Green Flame Dragon Sand seemed to be cracking.

Shi Yu was stunned.

When he glanced over, he saw that a thumb-thick crack had appeared in the middle of the Green Flame Dragon Sand, revealing a bright white mass inside.

"Is there something hidden inside?"

She hesitated for a moment, poured the killing spring water into another bucket, and then carefully took out the Green Flame Dragon Sand.

Close your eyes, touch it with your fingertips, don't look at it, and the feeling that your soul is about to be pulled out of your body will not appear.

She carefully touched the white center, which was warm to the touch, and a faint "beating" sound similar to a heartbeat came from inside.

"What's in here is... an egg?!"

Shi Yu opened his eyes, looking surprised.

"It takes ten thousand years for the Blue Flame Dragon Sand to be created. This egg has been wrapped in it for at least ten thousand years."

"There is still life coming. I wonder what kind of ancient creature it is... Can it be hatched?"

She shook her head, wondering why this piece of Blue Flame Dragon Sand, which should have been deep in the earth's core, appeared on the stall at the gathering.

The Qingyan Dragon Sand was born in the magma at the center of the earth. Its appearance now is probably related to the volcano 500 miles to the south.

After all... both of them gave her a strange and inexplicable feeling.

Perhaps it flowed out from the crater along with the magma.

"The original lump of stone must have been accidentally swallowed by some spiritual beast, and then cut out by the stall owner."

As a result, Shi Yu felt more and more that it was necessary to go to the volcano, and he should think of a way to find a time to go there.

Having said that, the "Illustrated Guide to Secret Treasures of Heaven and Earth" has very limited records on the effects of the Blue Flame Dragon Sand, so Shi Yu could only roughly guess its purpose.

Something like "understanding the mysteries of heaven and earth, increasing wisdom and well-being", and repeated mentions of words like spirit, soul, life and death, may be related to tempering the spirit and soul, and improving the realm.

I need to find an opportunity to study it carefully.

Shi Yu touched the egg inside along the crack, sensing its weak vitality, and sighed softly: "It's not easy for you to be trapped in it for thousands of years."

She herself had once had her spiritual veins drained of vitality, so she felt a bit of pity for this egg, an unknown creature that had been sealed for ten thousand years and had very little vitality.

After thinking about it, she put the whole piece of Qingyan Dragon Sand with the egg into the Yin-Yang Life-Knocking Bell and found a place for it next to the spring water.

Fresh spring water is a wonderful treasure that nourishes vitality, and Shi Yu has experienced its benefits many times.

This egg may also be able to grow stronger with the energy of the spring water.

After the Qingyan Dragon Sand was placed, a wisp of white mist like smoke and gauze gradually rose above the milky spring water, floating along the cracks of the Qingyan Dragon Sand and into the egg.

There was some reaction, which meant that her guess was probably correct.

Looking at the scene in front of him, Shi Yu no longer cared about it. He withdrew his consciousness from the Yin-Yang Life Bell and took out the sweet pine charcoal to prepare for refining the weapon.
