After all these years, the stones left behind were all as hard as iron. These stones could even be used as materials for refining weapons. They were all very precious items.

However, Li Yuanqing was not too interested in such things.

There were very few people down in the canyon, let alone any creatures. It was quiet down here and there was nothing. It was a desolate scene. Other than these black rocks, there was nothing left.

Water and plants were even more out of the question. They did not exist here. Moreover, even though the wind at the bottom was slightly weaker, it was still very stressful.

Li Yuanqing did not feel anything with such a shield around him, but he could feel that the wind had indeed weakened a little compared to above.

He seemed to have landed in a quiet area. The wind here was not strong. Li Yuanqing followed the direction of the wind and searched forward. He felt that he would definitely be able to find the Dragon Origin Crystal he needed if he found the place where the wind came from.

Sometimes the wind came from below, sometimes from the east.

Li Yuanqing headed east from the bottom of the canyon, feeling the gradually strengthening wind.

After walking for about ten miles, there was suddenly a moment of silence. The wind beside Li Yuanqing suddenly stopped. This stopped for only an instant. Then, a very violent wind blew over from the east. This time, the wind was even stronger than before.

The wind roared and blew past Li Yuanqing.

He realized that there was clearly a light ahead. It was pitch-black everywhere under the canyon. He could not see anything, not even a little light. Now that there was suddenly a trace of light in front of him, it was naturally extremely dazzling.

He continued forward in the direction of the light. Not long after, he arrived at a very deep pit.

This was indeed a deep pit. At the bottom of the pit was a very wide hole that connected to an unknown direction. And all this wind was blowing in from the hole below.

This huge pit was like a sealed bag. There was a constant black wind whistling from inside, and it was coming and going. Sometimes, a strong wind would suddenly blow towards the east, and sometimes, it would blow towards the top. This direction was strange.

It was these two violent winds that kept colliding with each other in the canyon, making the wind direction in the canyon very unpredictable.

The huge bag opened its mouth and kept emitting violent winds at a very stable frequency. Even though it was very powerful, Li Yuanqing could not feel anything at all. He did not find anything valuable at the bottom of the canyon.

Many places in the pocket lit up with specks of light. If one took a closer look, they would see that there were crystals embedded in the wall of the pocket. There was a lot of energy in this crystal, but it was not the Dragon Origin Crystal that Li Yuanqing was looking for.

Li Yuanqing ran to the wall and picked up a crystal. He placed it at the entrance of the cave. The light of the crystal was slightly dimmer. This was the light he had seen outside.

However, it did not seem to have any special value in his hand. The main thing was that the power at the exit was not that pure, so its value was not especially high. Of course, if it was only used to refine beginner-level Dharma artifacts, it should be enough.

Although the power inside these crystals was very chaotic, the requirements for beginner-level Dharma artifacts were still relatively low. These were enough.

Li Yuanqing slid all the way into the huge wind pocket. This place was like a very big slide. He did not even have to use any strength or do anything to go down the huge pocket.

However, without the protection of this armor, he would probably not be able to slide away no matter what. He would definitely be blown into pieces by the violent wind.

After sliding for an unknown period of time, it seemed like a long time had passed. The light inside was constantly becoming stronger, and the power of the crystals on the passageway outside was constantly becoming pure.

In the end, he finally stopped at a platform. It was only a small edge that a person could stand on. If he went down further, he would see that it was clearly a pure black liquid. These black things were the liquid formed by the huge pressure of the crystal above. This magma was very hot and contained endless energy.

Compared to the phosphorus mine, the power in this magma could only be used to refine tools. It was not much help to human cultivation, and the difficulty of mining was very high. If it did not form a stable crystal structure, humans would basically be unable to use it.

Therefore, despite that there was endless magma rolling here, no one had the ability to pluck this huge treasure.

Although Li Yuanqing was very careful just now, he still retained his vigilance this time. He did not slide straight down into the magma below. If he accidentally fell in, even with his cultivation, he would probably be skinned alive.

The crystal magma was very unstable. From time to time, an incomparably huge bubble would roll out. The bubble that emerged was like a huge ball that pushed against the dome. Then, it exploded, scattering a very hot aura.

Li Yuanqing finally knew why he felt the wind blowing out from inside become even hotter after he jumped down just now. It was until later on that it seemed like the wind had completely hit his face like magma and it was even hotter here.

Coincidentally, a new gust of wind formed here. From the vent, it spewed out. It was supported by endless crystal energy. In a colder place, it formed the crystals attached to the wall.

It turned out that this crystal stone lava was the reason why the Black Wind Canyon was formed. Moreover, it was also the reason why the wind in the Black Wind Canyon was so sharp.

It was because a small portion of the energy had leaked out, even though most of the energy of the crystals had been absorbed. It was like thousands of thin knives scraping on a person’s body, wanting to tear them into pieces.

Seeing that the wind was about to hit him, Li Yuanqing did not dare to be careless. He dodged to the side and attached himself to the nearby wall. A shield slowly formed.

The azure shield emitted a faint vapor, protecting Li Yuanqing in the middle.

There were many huge crystals hundreds of feet long on the dome. They emitted an unparalleled light that illuminated the large area of magma below. In this place, there were countless bubbles constantly spitting out on the surface of the magma. Not long after, a bubble would be spat out, forming a violent wind with a stable frequency.

Li Yuanqing’s gaze was completely attracted by the dome.

The energy of these crystals was the first to spray on the dome, forming a large area of crystals.

There were all kinds of crystals. It could even be said that rare items in the outside world were like cabbages here. They were very common and everywhere. As long as he took a small shovel and hammered it twice, he would be able to become rich.

After Li Yuanqing familiarized himself with the pattern of these things gushing out, he began to search around the dome.

“Black Mountain Crystal, Broken Jade Crystal, Stone Platform Crystal…”

These kinds of crystals were placed here normally. He would become rich if he took these crystals out to refine tools and Dharma artifacts.

Li Yuanqing searched the periphery for a long time. Although there were many types of crystals here, and many of them were rare items, he did not find the Dragon Origin Crystal he needed.

He had already circled around the outside. Although this place was big, with his speed, he quickly gathered everything. However, he could not find the Dragon Origin Crystal at the periphery. He could only continue searching inside.

Most of the bubbles were concentrated in the center. The center could be said to be very powerful. Basically, they were constantly spewing out crystal energy. If he wanted to reach the central area, he would have to let all the huge energy hit his body. It was a considerable risk.

However, Li Yuanqing’s motive for this trip was to find the Dragon Origin Crystal. Seeing that he could not find it outside, he could only go inside.

He slowly moved inside. This time, he rushed towards the deepest part of the crystal group.

There was a large pile of crystals of all kinds gathered there. The crystals formed at the intersection of this huge power were the purest. They were of hgh purity and could be used directly.

If merchants saw these treasures, they would probably want to dig them all up.

However, Li Yuanqing did not do so. He picked up the portion that he felt he needed. He could not take everything here away.

The closer he got to the middle, the faster the bubbles spewed out. Moreover, the power of the magma carried by them was even more turbulent. The azure shield wrapped around Li Yuanqing’s body was worn down very quickly, and the spiritual energy in his body was consumed faster.

Even with his strength, he could not last long at this level of consumption. He had to end the battle quickly. Li Yuanqing did not hesitate. After adjusting his position, he punched at the huge group of crystals and smashed them all down.

Those crystals were originally forcefully embedded together, but now that they were smashed down by this punch, they shattered in all directions. However, Li Yuanqing only waved his hand and pulled them all over. In the next second, his entire body disappeared and he appeared in the domain in the blink of an eye.

He looked at the crystal mine that had piled up into a small mountain on the ground of his domain. Smoke was still rising from it, and it was about to ignite the grass below.

Li Yuanqing waved his hand and summoned a huge lake of water from the lake. He poured it on the hot crystals and finally calmed them down. After the crystals stopped burning, their colors dimmed. It turned out that the ashes formed by the burns had covered their light.

Li Yuanqing sorted these crystals into different categories. After searching for a long time, he finally found a very small pure white crystal surrounded by a huge crystal.

This pure white crystal could be said to be very rare. The main reason was that these very pure crystals were usually transparent. It was difficult for white crystals like this to exist in these crystals.

However, this was the Dragon Origin Crystal that Li Yuanqing was looking for.

Li Yuanqing revealed a satisfied expression as he held the not-so-big Dragon Origin Crystal. The purity of this Dragon Origin Crystal was still very high, and the overall energy was still very rich. It suited his requirements very well.

And there was more than one piece here.

In just a short while, he had found six to seven Dragon Origin Crystals. This was a priceless treasure outside. If he took one out, it would be enough to shock the entire Ping City, let alone such a huge pile.

The conditions for the formation of Dragon Origin Crystals were even more stringent than these high-level crystals. Such an extremely complicated piece of Dragon Origin Crystal could only be born in an extremely pure environment.

What he wanted was this mix. It was unique to be able to gather such a huge and complicated energy into such a small crystal.

This Dragon Origin Crystal was also the key to completely suppressing the devil crystal. Without it, the power of the devil crystal would be very unstable if it was completely released.

After working for a long time, he finally found what he needed. Li Yuanqing heaved a sigh of relief. However, just as he was about to stop work, he saw an extraordinary item.

A very ugly-looking stone was mixed in these crystals of different colors. Originally, it was not enough to attract attention, but it was really too unique. It was even stranger than the Dragon Origin Crystal.

This stone was gray and looked no different from an ordinary stone by the side of the road. However, with the strength of the energy inside, how could such an ordinary stone exist intact?

Li Yuanqing held the small stone in his hand and could not feel any additional energy fluctuations. He squeezed hard, wanting to crush the stone. However, even with the huge strength in his hand, the gray stone was completely unscathed.

This was a magical thing. With Li Yuanqing’s strength, any stone in the world would shatter into powder if he pinched it, but this stone was still safe and sound.
