"The gold is beautiful! it looks as good as the boss's heart!"

I hope that I like gold only because it looks as good as a heartfire, but not because gold is valuable.

"Oh, dig down and see!" Queen Melissa didn't want to dampen hope, for gold was not produced in the Hengduan Mountains in the old world!

"Here?" said Queen Melissa, looking inquiringly.

"Hmm!"

Rustle~

As soon as Hope raised his hand, a sand pit quickly sank not far away, and after a while, a dark hole appeared in front of the two of them, and a cool breath rushed out of the hole.

The hole that sank down was the place that the four people dug just now.

"Sister Queen, is this a mine cave!?" Hope stopped the shovel in his hand and poked his head to look, it was pitch black inside, and he couldn't see what was under the hole.

Queen Melissa's hand flashed with purple fire, and a few violet flowers floated towards the cave, illuminating the scenery inside the cave, the steel rails that had long been rotted, and the iron tools that had rotted into black ash!

"It should be, this is a mine road! The mine road is in front of you but you don't know it, let's go down and have a look. ”

Hope asked, "Don't you call the boss?"

"No, let's go first, they'll find this hole when they come back. Queen Melissa jumped into the cave first.

"Squeak!" said Wish, Squeak jumped out of the hole.

The other side.

Liu Qingshan and the others also stopped, and the prospector was placed on the ground, "That's it?"

"Well, just hold it steady. Optimus nodded, took off the controller that had been on top of his head, and there was a flurry of dots, and several people couldn't understand the operation.

With the last point of Optimus, the prospector sank into the ground for more than half a foot slightly, and then a dull sound kept coming out, and some primary colors slowly appeared on the fuselage.

"Great, there's minerals down there, and they're of the highest quality!"

"It's amazing!" a few small bones looked at in amazement.

"What do these colors represent? "After all, Liu Qingshan came from the world of science, and he has never seen a pig on a tree, he has always seen a pig running, and he will not look like he has never seen the world.

"Smart, a color represents a specific mineral, the more minerals there are, the higher the color column will be, and vice versa. ”

Liu Qingshan understood as soon as he heard it, "The darker the color, the better the quality, right?"

"Yes!"

"It's really convenient! If it were so convenient for prospecting in my hometown, the earth would have been drilled into a pockmarked face long ago!"

"Don't be too happy, this is a very ordinary machine, the detection and range depth will not be very deep, and the distribution and geology also need to be considered!"

Liu Qingshan smiled, "You are an expert, you have the final say, so is there an energy mine down here?"

What he is most concerned about now is whether there is an energy mine.

Optimus shook his head, "No, you see there's no red pillar here. Only the Hengduan Mountains are rich in copper mines, and there are other associated minerals. ”

"What! Copper ore, not even iron ore. Liu Qingshan was hit hard.

"It doesn't have to be that way, any mineral has a use. And that's good news, because the veins are still there. We can always find other ones when we expand the range!Energy Ore is not so easy to find!and~. "Optimus doesn't really want to break morale.

"And what?" 000 literature

"And it will eventually devour energy, I didn't expect the mountain to be so badly damaged, and the energy mine is probably hopeless. Optimus waved his hand.

"I'm going to go! Fuck your sister, don't leave anything for Lao Tzu. Liu Qingshan directly burst into foul language, but also accepted the reality, "Alas, forget it, what can be dug up, how much can be exchanged for money!"

"Go down and look at the distribution and the geology. ”

"Digging a hole?"

“...... , don't estimate that there is an old mine hole below, right, lift the prospector!"

In the future, we will hold the prospector with power.

"Wait, what is this?" Liu Qingshan hurriedly shouted to stop, pointing to the two display pillars on the prospector and said, "What kind of mine is one purple and one blue?"

"......! there is no such marker!" Optimus took a closer look and saw that there were indeed two more markers, one purple and one blue, and the color was very bright.

"Hmm! it won't be the queen and hope, right!?" Liu Qingshan didn't guess randomly, but the iconic color of the heartfire was really obvious.

"Uh~! "Optimus has black lines all over his face, and there really is nothing else but this explanation.

"I'm going to go down to them! Liu Qingshan said helplessly, his words were completely deaf to the two of them.

"Whose is this?" asked Future, pointing to a shiny black marker.

"......! What kind of ore is black, kerosene and oil?" Liu Qingshan could think of these two circle-colored minerals.

Optimus scratched his skull, "Uh~!

"Then what is this black one? What a broken machine, your machine is not very reliable, is it broken!" Liu Qingshan suddenly remembered another possibility, "It's broken! Is it possible that the demon seed?"

Since the prospector can detect the fluctuations of human energy, it can also detect the final breath on the demon seed!

"Possibly!"

"Hurry up and go back!" Liu Qingshan finished speaking, unfurled his fire wings and galloped away.

"What's the situation?"

"Don't ask, go back first! The machine stays here. Optimus also drove the back to its original position, and the four of them could only keep up with the situation even though they couldn't figure it out.

There was no one in the original place for a long time, even Hu Squeak was gone, and I looked around to see that there was no trace of any demon seed, but there was no hole.

"That's where you got in!"

"How's it going?" Optimus chased after him from behind.

"There is no sign of the demon seed on the surface, the trouble is where the hell did they go down!?"

The entrance to the cave that was originally wide open had already been covered with yellow sand for unknown reasons, and it was no different from the rest of the ground, so no abnormalities could be found at all.

"It's not too far, make a hole on the spot!" After all, Optimus is a person with an IQ of two hundred and five, and immediately analyzed some reasons.

Liu Qingshan held his hand, and the Heart Flame Silent World Knife appeared, stabbing into the ground and drawing a big circle, boom~! The yellow sand fell, and an old mine really appeared on the ground.

Throw the heart fire down, the mine is dark and dry, and the rotten tools are all over the ground, it seems that it is the previous tool room, and the heart fire has turned into dust when it touches it?

"Hope!, Queen Melissa!"

Liu Qingshan listened attentively, and the echo of the empty array came, and it seemed that he had to go down to find out the reality, and he didn't hesitate to jump off the mine when he thought of it.

Optimus then drew their blades and wrapped them around the soul fire, and jumped down.
