Chu Yun didn't notice that when the entrance to the six-pointed star appeared, many sleeping demon beasts in the Water Moon Pool suddenly went crazy and scurried in the middle of the water body.

Most of the demon beasts in the pool are the type that eats and sleeps for a long time, and they don't move at all on weekdays, but now they are collectively running wildly, and even the top layer of the Water Moon Pool has been fluctuated.

The elders of the Water Moon Sect in the outside world, seeing the water surface trembling, thought that a disciple was about to come out, but the water surface quickly returned to calm.

They didn't think much of it, but whispered, "Now, there are only three children in the water." ”

"That's right, Liu Yin just came out, and he is not much weaker than Sun Ruman back then. ”

"The rest of Chu Yun, Dongfang Mingyue, and 6 Yang are sure to break the record, but I don't know who the three of them will come out in the end......"

When the water is calm, it is when the entrance to the six-pointed star closes.

It's a pity that Chu Yun didn't see such a magnificent scene with his own eyes, just the coercion leaked from below scared all the demon beasts into a mess.

At this time, he was in the world under the underground cavern, and his eyes were involuntarily attracted by a huge stone.

The area of this underground space is not large, it is round, and the walls are smooth, which is roughly equivalent to a larger room. Chu Yun thought at first that the space below would be wider than the bottom of the Water Moon Pool.

From the ground to the top of the head to the four walls, there are all kinds of intricate gold patterns.

There was no need to ask Lao Xu, Chu Yun could guess that this was still part of the formation.

The large stone in the middle of the room, in the shape of an ellipsoid, is blue all over, about half a person high, and although this blue is not rich, it is very pure.

At the bottom of the stone, there are also many strange patterns, and there are mysterious fluctuations scattered on it.

"Old Xu, the magic weapon you are talking about, could it be this big stone?" Chu Yun was a little puzzled for a while, this stone felt a little dreamlike when he saw it, and he didn't think anything else was powerful.

"Take a closer look. "Old Void Road.

Then, Chu Yun also cautiously walked to the side of the stone.

After getting closer, Chu Yun could see through this layer of light blue, and he could see that there seemed to be some colors in the stone. The light blue of the outer layer is more like a shell.

"This shell on the outside seems to be a spirit stone. Chu Yunhu said suspiciously.

Whether it is the color or texture of the shell, it is somewhat similar to the high-grade spirit stone, but it seems to be more pure.

"This is not a spirit stone, it is a spirit crystal. There was some surprise and joy in Lao Xu's tone.

"Lingjing, such a big piece, isn't it wealth!" Chu Yun was also taken aback.

Spirit stone, in the final analysis, is a kind of ore, according to its quality, it is divided into upper, middle and lower grades, and spirit crystal is the essence of spirit stone. Only in a few spirit stone deposits, there will be a very small amount of spirit crystals, spirit crystals, which are the essence of mineral deposits, and their value is hundreds of times higher than that of high-grade spirit stones.

It is precisely because of the rarity and high price of spirit crystals that this item is destined not to become a currency in circulation.

Spirit stones can be used directly for cultivation, and the effect is excellent, let alone spirit crystals?

Similarly, even spirit stones are not something that ordinary people can afford to waste, let alone spirit crystals.

And what Chu Yun was in front of him was actually such a huge piece of spirit crystal, how high its value was, Chu Yun couldn't calculate it anyway.

However, Lao Xu's words were like a basin of cold water poured on top of Chu Yun's head: "Master, don't get excited, Lingjing, it's just the outermost layer." ”

"Alas, it's a pity. Chu Yun looked a little painful.

Unexpectedly, Lao Xuan couldn't help but laugh and said: "Master, do you know how this layer of spirit crystal came from outside? The things wrapped in spirit crystals must be more precious!"

"By the way, there is no spirit stone mine here, how can there be a spirit crystal?" Chu Yun also thought of this question, "Could it be that it was condensed by himself?"

"Exactly. Lao Xuan sighed, "For a long time, a large part of the aura in the depths of the Water Moon Pool will flow into this small underground space, to be precise, into the things inside the spirit crystal. Because of the long-term accumulation of spiritual energy, a layer of spiritual crystals was slowly formed on the surface of that thing......"

"How many years has this to be accumulated, and how much aura has to be absorbed? Chu Yun couldn't help but touch the surface of the big stone.

As soon as he put his hand down, his heart trembled.

Rumble!

It was as if a terrifying roar sounded in his head. Suddenly, cold sweat appeared on Chu Yun's forehead.

He took two steps back, unable to come back to his senses: "What the hell is this?"

Lao Xu's tone became particularly serious: "I'm not sure for the time being, but if it can be enshrined here, there is no need to doubt its value." Master, first peel off the outer layer of spirit crystals, and then make a decision. ”

Chu Yun stared at the pale blue stone, and he actually felt awe.

He followed Lao Xu's instructions and took out the long sword from the immortal mansion.

"The master condenses mana on the tip of the sword, and gently scratches it on the spirit crystal, don't use force, the quality of the spirit crystal is different from the master's mana, and there will definitely be rejection, and this kind of rejection will make the spirit crystal crack automatically. ”

As soon as the old void's voice fell, Chu Yun cautiously raised his flying sword, and slashed down on the side of the oval stone from top to bottom.

This time, he only indirectly touched the stone with the tip of his sword, and increased the power of the immortal mansion to protect himself, so he was not shaken back.

When the sword touched the pale blue surface, a small crack appeared in the direction of the sword's tip.

Click

"On the other side, a knife is also taken. Lao Xuan continued.

Chu Yun repeated his old tricks, and drew a total of four swords and four cracks on the stones, which were symmetrical in pairs.

"Knock on the top floor...... Be careful. "The old void in the Immortal Mansion seems to be a little nervous.

Chu Yun stabilized his mind and gently knocked the crack junction at the top of the stone with the back of his sword.

In an instant, the stone was split into four.

To be precise, the outer layer of the spirit crystal was divided into four, like an eggshell being cut into four pieces and slowly fading.

The spirit crystal shell did not shatter, it spread out like petals. Between the four crescent-like spirit crystal shells, the things inside finally appeared in Chu Yun's sight.

"Old Xu, I remember that before I came in, you said that what is hidden here must be a magic weapon against the sky, right?" Chu Yun was not excited, but looked at the thing in front of him in a daze, with a very unnatural expression.

"This ...... I didn't expect that either. "The old man eats and eats.

"Don't talk about the magic weapon against the sky, even if it is a magic weapon, I will recognize it......" Chu Yun's voice trembled a little, "But, after peeling off the spirit crystal shell, what happened to an egg coming out?!"
