Both of them were disappointed when they saw it. Ah Fei didn't dig up any raw stone at all. Her Black Death Demon only dug up a strange thing.

"What is this?" Chu Jun looked at the things in the pit, his eyes full of confusion.

Li Xiu was also looking at the thing, but couldn't figure out what it was.

The Black Death Demon had just dug a pit more than three meters deep, and inside it there was a red spherical object about the same size as the large yoga balls that women use for yoga.

The spherical object was not made of artificial material. Its surface was covered with something like scales, but those scales looked more like metal.

If it was a demon spirit, several people did not sense any demon spirit aura on it. Chu Jun had the skill of inspiration, so if it was really a demon spirit, he should have discovered it long ago.

If it wasn't a demon, then what was it? A new species that had never been discovered on Earth? Or was it something created by humans?

Ah Fei directed the Black Death to move the things out. The three of them looked at them carefully for a long time but could not figure out what they were.

There are no cracks on the ball, which first eliminates the possibility that something has shrunk into a ball.

They had never heard of any creature that could grow scales on its eggs, and how big a creature would it be to lay such a large egg? Even if the dinosaurs were resurrected, it was hard to say whether they could lay such a large egg.

"Is it a man-made thing? Who would make such a thing? What's the point of burying it here?" Chu Jun touched the scales of the thing, but he didn't feel anything. The texture was similar to normal metal.

"Do you think this could be a fruit?" Fei pondered.

"Fruit? What kind of fruit can grow so deep underground?" Chu Jun felt that Ah Fei was just daydreaming.

"Maybe my expression was wrong. What I meant was, is it possible that this is a plant, like the lotus roots, potatoes, sweet potatoes, etc. buried in the mud?" A Fei explained.

"We'll have to cut it open to see for sure." Chu Jun thought it unlikely that any fruit would have a metal shell and scales on the outside.

After studying it for a long time, I still couldn't figure out what it was, so I finally decided to cut it open and take a look.

The three men ran far away and hid behind a big rock. Chu Jun controlled the Dark Blue Knight and slashed at the metal ball on the ground with a sword.

With a clang, the metal ball was smashed away by the sword of the Dark Blue Knight, but it was not damaged.

"It's so hard, it looks like it's not a fruit." Chu Jun was talking when he suddenly saw that thing actually moved by itself.

The scales on the outside of the metal ball folded and shrank downwards one by one, and soon the contents were revealed.

There were still the same scales inside. When the outermost scales were folded and shrunk to the bottom of the sphere, the second layer of scales also began to fold and shrink downwards.

Layer after layer, this thing is just like an onion, with scales peeling off layer by layer, but the same scale structure remains inside.

"It has more than ten layers, right? How come it has more layers than an onion? What on earth is it?" Chu Jun stared at the metal ball, which was almost as big as a basketball, and said with a strange look on his face.

"If I knew what it is, I wouldn't be hiding here." Li Xiu said, staring at the thing.

Several more layers of metal scales peeled off, and the scales folded and piled up layer by layer below formed a column that looked like a pineapple, and the ball on the top was still peeling off the scales.

Finally, after the last layer of scales was folded down, the three people were surprised to find that inside the layers of scales, there was actually a fist-sized, translucent white sphere like jelly.

Ah Fei suddenly seemed to have thought of something, pointed at the thing and said, "I remember now, I thought this thing looked like fruit just now. Look, does it look like a large lychee, except that the skin is thicker and the flesh is inside."

After hearing what Ah Fei said, Li Xiu and Chu Jun really felt that they were somewhat similar, except that the skin was thick and the flesh was small. After peeling off the layers of such a big thing, only the flesh the size of a fist was left.

"This thing can't really be a fruit, right?" Chu Jun swallowed.

"You'll know if you try it." Li Xiu said with a smile.

"How can I taste it? Who knows if that thing is a fruit? Even if it is a fruit, what if it is poisonous?" Chu Jun is not stupid, how could he possibly taste it.

The three of us looked at each other, and no one dared to be the first to try it.

After waiting for a while and finding no danger, three people came out from behind the big rock and came to the side of the thing to take a look.

"Oh my god, it has a sweet fruity smell. Could it really be a fruit?" Chu Jun exclaimed immediately after he leaned closer to smell it.

Li Xiu also sniffed it and nodded, "It really does smell a bit like the sweetness of lychees, and seems to be mixed with the flavors of pears and bananas. It might really be a fruit species that has not yet been discovered. Do you want to try it?"

"Forget it, it's too risky. Let's continue mining. How reliable is that evil spirit? If there is a ruby ​​mine in this valley, we should have dug it up long ago if we are digging like this." Chu Jun muttered.

No one dared to taste that thing. Li Xiu controlled the magic spirit and moved the thing to the corner nearby. He and A Fei continued to dig holes to find rubies.

Who knew that instead of finding the ruby, they soon found the red ball.

Although they didn't find any rubies, they did find seven or eight of these red balls, which made the three of them a little depressed.

The shells of these red balls are indeed very hard. Li Xiu plans to take them back to let Ximen Guan take a look. Maybe they can be used as materials for magic armor.

"It seems that we have most likely been deceived by that great king. There is no ruby ​​mine in this broken place." Chu Jun was so tired just by looking at the dug stones that he collapsed on the ground and said.

"This is not right. If the Great King is really that scheming, he must have had his reasons for tricking me here. It should be good for him. How can we dig a hole here to benefit him? It can't be that he wants to eat fruits and tricked me into coming here to dig these fruits and bring them back to him?" Li Xiu felt that this shouldn't be the case.

"So what do you think we should do? Continue digging?" Chu Jun said.

"How about this, let's get all the monsters here, and we'll dig a big, deep hole and see if we can find anything. If we don't find anything, we'll go back." Li Xiu also felt that the chances of digging out rubies were probably slim.

Several people put all the demons into a pit and started digging. Some were digging, some were transporting the excavated soil and rocks, some were picking up stones, and some were taking out the garbage. These demons worked non-stop and worked harder than the workers in a sweatshop.

Bang!

When the pit was more than 20 meters deep, a black death demon's feet sank, as if he had stepped into air, and he disappeared in an instant. Only a hole was seen over there.

"No way, is there a cave demon here too?" Li Xiu was shocked. After making sure that there was no problem with the ground nearby, he hurried to the edge of the cave.

Looking down, I found that there was a tunnel-like passage extending to both sides at a depth of about two meters.

Li Xiu jumped down and looked at both ends of the passage and was immediately shocked.

At one end of the passage, there was a huge creature wriggling. It looked like a giant earthworm, but its body was covered with red scales and it was constantly digging holes.

"What's going on down there?" Chu Jun asked at the gap above.

Li Xiu quickly made a gesture to keep quiet, and then motioned him and A Fei to come down together.

After Chu Jun and A Fei tiptoed down, they saw the giant earthworm that was swallowing up the soil and rocks to drill a hole, and their faces changed slightly.

That thing was like a digging machine. Its lotus-like mouthparts constantly swallowed soil and rocks, which were then discharged from the hole at the back of its body. It dug holes very quickly.

That thing didn't seem to notice Li Xiu and the others, and continued to dig holes there.

Chu Jun quickly used his inspiration skill, and then lowered his voice and said to Li Xiu: "This thing is a demon spirit, named Stonebreaker, and it's an A-level demon spirit. I think there may really be a gem mine here, but the rubies in the gem mine may have been filtered and swallowed by this thing, so we can't dig up rubies."

Li Xiu thought so too, and was about to summon the Jedi to kill it, but he saw that the Stonebreaker suddenly stopped.

The three thought that the Stonebreaker had discovered them, but after a few tremors, the Stonebreaker squeezed out a red ball from another smaller hole at the back, and then continued to drill holes.

Li Xiu and the other two looked at each other and felt sick.

No matter how you look at it, the red ball looks like the excrement of the Stonebreaker after he had eaten too much. Thinking about how the three of them had just smelled it from such a close distance and said there was this or that fragrance, they all felt nauseous and wanted to vomit.

Li Xiu directly summoned the Jedi Knight and rushed forward. The Jedi Knight chased after the Stonebreaker's body and slashed out with a bloody slash, which directly cut a big gash in the Stonebreaker's body. The body that was almost broken into two pieces was still able to move, and he struggled to escape.

This demon was strange. Although its body was quite large, it was not good at fighting. The Jedi chased it and chopped its body into pieces. After a few cuts, this guy became completely motionless.

When the Stonebreaker struggled to escape, it collapsed the tunnel a little. The three men dug out the collapsed soil and rocks and found a magic core in its body.

That magic core was nothing special, just an ordinary A-grade magic core, not even of good quality.

But in addition to the magic core, they also found a ruby ​​inside the Stonebreaker's body.

"Is this thing a ruby?" Chu Jun widened his eyes, looking at the huge crystal sphere in front of him with some disbelief.

In fact, this crystal clear, ruby-like ball, which appears to have no impurities, is only as big as a basketball.

But if it is really a ruby, it is not an exaggeration to describe it as huge. Such a ruby ​​must weigh dozens of kilograms. Compared with rubies weighed by carats, it is a behemoth.

"It looks a bit like it, but I've never seen or heard of a ruby ​​this big and this pure." Li Xiu looked at the ruby ​​ball closely. He couldn't see any inclusions inside it. It was so pure that it was hard to believe it was a ruby.

"Let's get it back first. I don't know if there are other rock crushers underneath. If there are a few more of these things, this ruby ​​mine will be almost ruined. It will be impossible to dig out rubies anymore." Li Xiu said helplessly.

I thought I was finally going to have money, but I didn't expect it to be all in vain.

Now he could only hope that there were no other rock breakers down there, and that the gem mines here had not been eaten up.

Li Xiu himself did not plan to dig anymore, and asked Sha Chu to find a few professional prospectors or gem hunters to come and take a look.

After hesitating for a while, Li Xiu transported the red balls back and asked Ximen Guan to check them to see what they were.

Although I strongly suspect that these red balls are the excrement of the stone crushers, the scaly shell is more like metal, so maybe they can be useful.

When Li Xiu placed a ruby ​​ball that was slightly larger than a basketball in front of Ximen Guan, Ximen Guan took a look, frowned and said, "Why did you bring a glass ball over here?"

"What glass ball? It's a ruby." Li Xiu said.

"Ruby, are you sure?" Ximen Guan looked at the ruby ​​ball with disbelief. Even if it was an artificially synthesized ruby, it would not be easy to get one of this size and clarity.

"You will know if you test it." Li Xiu actually had no idea whether the ball in the Stonebreaker's body was a ruby ​​or not.

If it is really a ruby, Li Xiu feels that his trip is not in vain. Such a large ruby ​​ball can be sold at a sky-high price.

Ximen Guan didn't believe that this thing could be a ruby. However, after testing it, he found that it was indeed a ruby, and there was no trace of artificial synthesis. All indicators were the same as those of a natural ruby.

Ximen Guan thought the test was wrong, so he debugged the instrument himself and retested it with several different types of instruments. The result was the same. This was a natural ruby, and it was so pure that there was almost no impurities visible to the naked eye.

"How is it possible to have such a big ruby?" Although Simon still couldn't believe it, the test results were there and he had no choice but to believe it.

"Where did you get such a natural ruby? It's very valuable. You might as well sell it and exchange it for some equipment." Ximen Guan had no interest in the gemstone and only wanted to exchange it for equipment.

"I still have a use for it." Li Xiu immediately took the ruby ​​ball back. Are you kidding me? How could this thing be sold casually?

In order to comfort the somewhat unhappy Ximen Guan, Li Xiu asked Chu Jun and A Fei who were waiting outside to bring in a large box filled with those red metal balls.

"Old sir, I found some good things for you. See if you can use them." Li Xiu said, pointing to the red ball in the box.

"What is this?" Ximen Guan obviously didn't recognize what it was.

"Good stuff." Chu Jun controlled the Black Death Demon, placed a metal ball on the table in front of Ximen Guan, and then smashed the metal ball hard.

The next second, the scale-like shell opened layer by layer, finally revealing a fist-sized object that looked like lychee flesh.

"Is this a man-made device? It doesn't look like it. Could it be some kind of plant? That doesn't make sense either." Ximen Guan moved closer to the pulp-like thing and sniffed it. He seemed to have thought of something and suddenly stretched out his finger and scraped it. Some transparent ** stuck to his finger and he put it in his mouth.

This action made Li Xiu and the other two feel so sick that they almost vomited on the spot.

After tasting it, Ximen Guan showed excitement: "Where did you find this thing? This is a natural catalyst that can be used to refine magic spirit materials. I have seen some in Changshengtian before, and it tastes like this. It turns out that catalysts are extracted from this kind of thing. Where did you get it from? With this thing, I can save a lot of time when refining magic spirit wood."

"Uh." Li Xiu and the other two looked at each other, and no one spoke.

"What are you looking at? Tell me quickly, this is a good stuff. Do you have any more? Can you get it in the future?" Ximen Guan asked anxiously.

"Yes, there is..." Seeing that Chu Jun and A Fei were silent and completely ignoring his expression, Li Xiu had to cough lightly and told them the origin of this thing.

Originally, they thought that Ximen Guan would have some uncomfortable psychological or physiological reactions after listening to it.

Who knew that after hearing this, Ximen Guan smiled and said, "For scientific and technological workers, we only care about the constituent elements of matter. Nothing else is important. Let alone excrement. I have tried everything for research. You are really making a fuss. Such good things cannot be taken away by others. You should organize people to continue digging as soon as possible. It is best to dig them all back for me without leaving any."

"See? This is professionalism. You all should learn from it and stop being so jumpy all the time." Li Xiu thought about it and it made sense. Ximen Guan had been imprisoned for decades and had done things like eating, drinking, defecating and urinating in a sink. This was nothing, so he said to Chu Jun and A Fei.

Chu Jun and A Fei looked at Li Xiu with contempt, as his reaction just now was the biggest.

"You are the one with vision, and I am superficial." Chu Jun took the initiative to admit his mistake to Ximen Guan.

"You are still young, and it's normal that you don't have enough vision. You can learn slowly in the future. Stop talking nonsense and organize people to dig." Ximen Guan urged them to dig the red metal balls quickly.

After the three people left, the old official closed the door, rushed into the bathroom like a fly, and vomited violently in there. The noise made people afraid that he would vomit out his stomach.

He used to eat, drink, defecate and urinate in a water trough, but that was running water. He drank water from the upper stream and defecated and urinated in the lower stream. Moreover, it was his own thing, so he could accept it psychologically.

What's more, we are used to the good life now, so how can we endure such hardship again?

Li Xiu asked Chu Jun and A Fei to dig out the metal balls, while he went to the construction site and went deep into the cave again wearing the ghost mask demon costume.
