Jin Buhuan waved the Golden Snake sword in his hand. The sharp sword Qi was inserted into the crystal and dug out the spiritual crystals. After digging out the crystal stones, Jin Buhuan put them into the ring.

These spirit stones are also a cultivation material for him. Naturally, he will not miss them,

After several hours of excavation, Jin Buhuan excavated several tons of spirit stones, and then continued to go deep below to continue exploration. The first layer, the second layer and the third layer, Jin was surprised without changing his eyes, because the spirit mines of each layer were different. The more the bottom layer was, the better the crystal stone was.

After a while, Jin Buhuan came to the eighth floor. He looked around. The color of the spar here had changed from purple to black.

"Black crystal?"

Jin Bu changed his surprised eyes. He thought amethyst was very advanced. There was the highest grade black crystal here.

Black crystal is also transparent. Its strength is at least twice that of purple crystal. It is located in the depths of the earth. It is obviously compressed more violently, and the more fighting crystals gather, so it is black.

Click ~

Jin Buhuan pinched it hard. Unexpectedly, he crushed it twice this time. At the moment when the black stone was crushed, a fighting spirit gushed out, just like water vapor. Jin Buhuan quickly ran the burning formula and the internal skill turned.

His pores are open, like his mouth sucking and fighting madly.

"This crystal stone is enough..."

Jin Buchang was surprised that the fighting spirit in his body was filled with such a spar. Just one is enough for cultivation. According to his guess, the black spar is suitable for the strong above the five-star duel saint.

However, there are too few black crystals. Generally speaking, the strong people above the five-star duel saint will use tons of purple crystals, so the child emperor uses more cultivation materials than all of them combined.

If there is a black spirit stone, it will be of great benefit to the cultivation of Tong Huang.

"Yes, yes..."

Jin Buhuan grinned. They need such materials as the foundation for the development and growth of the holy palace. In a few years, even if the holy palace is not as good as Jiuyou palace, it will develop and grow and cultivate more fighting saints.

"This is the eighth floor, so the ninth and tenth floors should also be black crystal."

The corner of Jin Bu's mouth rose slightly, and then continued to enter along the depth of the hole. As he guessed, the eighth, ninth and even tenth floors were black crystals. The seventh to fifth floors are purple crystals, and the first to fourth floors are transparent white crystals.

It can be seen that the more in-depth, the color of the crystal will be different, and the power contained will be different. Not long ago, Jin Buhuan came to the tenth floor. This spirit mine was transparent and black. These spirit stones seemed to be able to swallow the light source. Without changing the whole body, Jin suspended different fire, and soon lit up this black spirit mine.

Buzzing——

"Eh? Can it still shine?"

Jin Buhuan was slightly surprised. It turned out that these spiritual mines could absorb the light source, and then emit light by themselves. The light was refracted from the crystal. It was very bright. Jin Buhuan looked up and found that he was like the deep universe. Those scattered spots were like countless twinkling starlights.

This scene, some dreams.

If you can move the whole cave away as a base for cultivation, it would be great. Unfortunately, it's a little difficult to move even the hole. Unless he can use the space God bead, but Jin Buhuan weighs it, I'm afraid the space God bead can't devour the whole spirit mine. The reason is not the space God bead, but him.

The energy contained in this spirit mine was so great that he could not swallow it for a moment.

"If only Tong Huang were here..."

With the strength of Tong Huang's six star fight saint, we should be able to move this hole away. On this thought, Jin didn't dig here without changing. He planned to let Tong Huang do it again in person.

"This should not be the last floor. It means that there are still, perhaps, eleven, twelve, thirteen, or even a hundred."

It's not clear how many spirit mines are buried here, but what he can perceive is that there are still spirit mines below.

If so, it's true that they have no other worries about cultivation materials for at least a few decades. With such a spiritual mine, there are enough materials,

In particular, the last three layers of black Lingjing are almost priceless. Even for emperor Jiuyou, they are a treasure. Because it can cultivate a lot of fighting saints.

"I want to go down and see how many spirit mines there are."

Jin Buhuan didn't intend to stop at the tenth floor. He planned to go further and have a look.

Boom——

On such a thought, Jin Buhuan's figure wrapped the flame and drilled madly towards the bottom.

Boom! Boom! Boom!

Working hard, the gold did not change, just like a drill bit, and directly dived hundreds of meters.

"Lying trough!"

Jin didn't change his eyes, because hundreds of meters below the tenth floor, there was another black spirit mine, and the grade was not low.

Boom——

He dived again. As a result, he found the 12th, 13th and 14th spiritual mines at 500 meters, 800 meters, 900 meters and 1000 meters. They were all black spiritual mines.

At this moment, Jin Buhuan knew how terrible resources were hidden here. Fortunately, it's on their side, otherwise it would be painful. On such a thought, Jin Buhuan dived again.

Buzzing——

This time, when he opened his eyes, he saw an unusual scene.

A blue light came through. The blue light was like water. There was a pure and soft light, which made Jin lose his mind for a while, because there was no blue spirit stone in his memory. As soon as he opened his eyes, it was not surprising that there were blue spirit crystals piled up here.

"Blue crystal?!"

Jin Bu changed his mind. He only heard of purple and black Lingjing, but never heard of blue Lingjing. What is this?

Creak ~

Jin Bu bought a piece of Lingjing. He pinched it hard. Unexpectedly, this piece of Lingjing seemed very fragile. As soon as he pinched it, it was crushed.

"Eh?"

Jin Buhuan was surprised that after the blue Lingjing was crushed, it did not turn into fighting spirit, but drew out small rotating black holes, and then the black holes disappeared quickly.

"The power of space!"

Jin Buhuan was surprised to find that this Lingjing didn't have the power to fight, but contained the mysterious power of space. Jin Buhuan immediately used the system to query, and he was surprised. It was really not the Lingjing of cultivation.

This spiritual crystal is called ethereal crystal!
