The stones on the whole Horseshoe Mountain are gray except for cyan, but where there are stone veins, the color of the stones is different, and the color is neither gray nor green, a bit of black and purple.

Luo Xu found this black-purple stone under a gray boulder, and he kicked the thousand-pound boulder away, and found that as the old lady said, there was a big hole underneath.

"Haha, the amethyst should be in there!"

Amethyst is hidden deep in the belly of the mountain, and this passage must have been left behind by the previous amethyst miners. Luo Xu got into it, only to find that the space in it was larger than he imagined, walking in it, straightening his waist, there was still a distance of about thirty centimeters above his head.

Traces of previous mining can be seen everywhere, and from time to time you can see the tools left behind by the people of that time.

Broken sticks, rusty axes, discarded ropes......

"Oh, no wonder Sister-in-law Zhen said that their village was very rich in the past, and they must have made a fortune by selling amethyst. But resources are not renewable, and there will always be a time when they are depleted, so life is so miserable now. ”

Luo Xu walked all the way, and obviously felt that the road under his feet was sloping downward. The deeper you go, the warmer it gets in the passage.

"I'm not heading to the center of the earth. ”

The heat is getting stronger and stronger, and the passage is not ventilated, so if it were an ordinary person, it would be impossible to continue going inside.

Luo Xu knew that the heat was coming from the center of the earth, and walked forward for a while, but there was no road ahead.

He sensed that the temperature in his location was about fifty degrees, and ordinary people couldn't work at that temperature, so this mine was only mined here.

"It's probably all unmined, and there may be a lot of amethyst in it. ”

Luo Xu picked up a shovel on the ground and began to dig, but the shovel broke as soon as it touched the surface of the rock formation. The wooden handle of the shovel has long since decayed, and the wood can turn into ash with a single blow.

"Nima!"

Luo Ku took out a sword from the virtual space and slashed at the rock formation with the sword. Sparks flew everywhere, and after cutting for a while, I saw that the rock layers fell off piece by piece and landed at Luo Xu's feet.

"Amethyst!"

After digging deeper for about ten meters, Luo Xu saw a transparent crystal the size of a fist. He shone it with the flashlight he carried with him, and the light shone into it, and sure enough, the transparent crystal on his hand immediately turned purple.

"That's it, finally let me find it!"

Luo Xu looked at this small amethyst stone with ecstasy, and after looking for so long, he finally found this thing, which made him extremely excited.

He deposited the small piece of amethyst in the storage wrench and continued digging. Almost a few meters into it, you can find a small piece of crystal. Gradually, Luo Xu didn't know how many pieces he had found, anyway, he was digging all the way down.

To Luo Xu's dissatisfaction, the amethyst stones he found were all small, the smallest one was only as big as a glass marble, and the big one was only the size of a round eggplant.

"Isn't there a bigger one?"

Luo Xu continued to dig and found some small pieces. No matter how big or small, he took it all and stuffed it all into the virtual space.

Unconsciously, Luo Xu had already excavated about five hundred meters deep into it, and his tolerance to heat was very strong, and he focused on mining amethyst, but he forgot to feel the heat around him. Unbeknownst to him, the temperature around him had exceeded 300 degrees Celsius.

When!

Luo Xu went down with a sword, as if he had slashed something.

"What a hard thing, what is it?"

The previous rocks, as long as a sword went down, would inevitably crumble, but this thing didn't do anything at all, but it shook Luo Xu's mouth painfully.

"I don't believe it!"

This time, Luo Xu had enough strength and slashed hard, only to hear a loud noise, and the sword in his hand was popped out, but the thing that was black on the surface also showed a little bit of its true face.

"Yes...... Amethyst?"

The black thing left a sword mark on the surface, and a little purple light appeared at the sword mark.

Luo Xu hurriedly sped up his speed and shoveled away all the rocks and soil layers around this black thing. The more he shoveled, the more frightened he became, the volume of this black thing was too large, even bigger than the thousand-pound boulder pressing against the entrance of the passage.

"What the hell is this?"

Amethyst is transparent and only appears purple when light hits it. But this thing was originally purple, and purple was its primary color. From this, it can be inferred that this thing should not be amethyst.

However, Luo Xu did not give up the exploration of this thing, he dug it completely out of the rock and soil layers. This thing is too big, the size of a small boat, and the weight has reached about 10,000 catties.

Luo Xu carefully made a hole in this huge stone, and found that this thing was really purple inside, although it was different from the transparent state of amethyst, but it gave him a familiar feeling, which was similar to the feeling that amethyst gave him.

"This thing must be inextricably linked to amethyst!"

Luo Xu made this inference, he put the huge stone into the storage wrench, and then planned to continue digging.

But the moment he put the huge stone into the storage wrench, the cave shook violently, and the ground shook as if the mountains were shaking.

"Oh no! This hole is going to collapse!"

Luo Xu hurriedly ran out as if he was dying, and the speed was extremely fast. Behind him, the mine was collapsing at a breakneck pace, and if he slowed down a little, he would be buried under the falling stones.

Running wildly all the way, Luo Xu saw the light and knew that he was about to reach the entrance of the cave. A minute later, he ran out of the mine, only to find that it was not only the inside of the mine that was shaking, but the entire Horseshoe Mountain shaking.

"It's ...... Earthquake?"

Luo Xu thought of Wang Baxian and hurriedly rushed to the place where Wang Baxian was resting. He had been in the mine for so long that it was dark when he came out.

rushed to the place where Wang Baxian was resting, and found that Wang Baxian was no longer there.

"Lao Wang, Lao Wang......"

Luo Xu shouted the name of Wang Baxian loudly, but only the sound of the earth shaking and shaking answered him.

"Lao Wang is such a clever person, maybe he has already gone down the mountain when he sees that the situation is not right. I'll look down the hill. ”

The rocks under his feet were collapsing and rolling, Luo Xu had no choice but to fly against the wind, and in a blink of an eye, he arrived at the foot of the mountain, but there was still no trace of Wang Baxian.

"That old fellow isn't a man who can be idle, he can't be looking for it himself while I'm away, is he?"
