Ling Li came to the cabin, and the girl in charge of the registration was only a round-faced girl sitting behind the table on duty. The others should have gone to have dinner.

"Get a mine pickaxe and a basket for one person." Ling Li walked over and took out his student ID to register.

"Didn't you have completed the quota?" The girl with round face seemed to remember Ling Li and asked strangely.

"I like mining. I'm going to dig more while there are fewer people now." Ling Li grinned.

"Haha, mining can't make much money." The little girl also smiled, and after registering Ling Li in her hand, she returned the student ID, "Choose the tools yourself."

Ling Li nodded, came to the ore storage site on the side of the wooden house, picked up a mine pickaxe, and then casually found someone to carry a basket on his back, and walked slowly towards the tunnel he had detected yesterday afternoon.

There were more students coming to mining today than yesterday, and most of them did not complete the task and were still working in the tunnel. Ling Li held a mine lamp in his hand and walked into the tunnel. The sound of mine picks hitting the ore came from the tunnel.

After passing by some classmates who were mining, no one knew each other, so no one greeted him. But occasionally some people would look at him strangely, maybe they couldn't figure out why this person is also coming to the tunnel to mine now.

This should be another unlucky guy who returned disappointed from the hunting team!

As he continued to go deeper, no sound came out before him. Ling Li followed the mark he made on the rock wall yesterday and turned around. Since he stopped detecting, the speed was much faster this time. After walking for only about half an hour, he came to the end of the tunnel where he dug the source energy crystal yesterday.

Ling Li thought about it and lit the open flame mine lamp in his hand, fastened the glass cover, and hung it on the rock wall on the other side. Otherwise, if someone came over and found that he was touching the mine veins, he would not have to treat it as a ghost to scare others to death!

He looked behind him again, confirmed that there should be no one within 200 meters, then took a deep breath, stretched out half of his body and pressed it on the rock wall inside.

"Drip, I found that it can absorb energy at 8 meters in front of the right. Did it absorb it?"

"Drip, I found that it can absorb energy by 1.4 meters ahead of the right. Did it absorb it?"

This time there were two more sounds, and Ling Li was stunned. Is this the rhythm of preparing to dig a cave by himself?!

The granite on the right is too hard, and the edge of the vein on the left is better to be dug. These source crystals seem to be generated along the gap between the granite and the iron ore veins.

Don’t worry about these first, dig out these two source crystals first.

As long as this thing is brought back to the city, it can be exchanged for several stacks of large bills at any time!

Thinking of this, Ling Li was immediately full of energy.

An hour later, Ling Li dug out a cave that was more than one person high and nearly two meters deep at the end of the iron ore vein, and then he held the first source energy crystal in his hand. This crystal was about the size of a big finger, and was about the same as the two I got yesterday. Ling Li was very happy after getting the crystal, carefully put it in close proximity, picked up the kettle, drank a few sips of water, and continued to dig with great enthusiasm.

When he was about to dig the second source crystal, Ling Li found that every time he pulled down his pick, there seemed to be an echo sound. Obviously, the rock wall opposite was empty, but he didn't expect that he would dig two tunnels soon. He didn't think much about it, so he simply dig to smash it. He smashed it for more than a dozen times. Suddenly, with a bang, the mine pickaxe had penetrated the stone wall, and the ore that had fallen fell to the ground, and it actually echoed continuously. It seemed that there was a large space inside, not a tunnel.

Ling Li felt curious and stretched his right eye to the hole knocked out by the mine pickaxe and looked inside, and found that there was a large lava cave inside, which turned out to be a different kind of cave.

He suppressed his curiosity and carefully dug out the second source energy crystal. After putting it away, he used a mine pick to dig the hole a little bigger.

At this time, a large hole had been broken on the rock wall, and his head could be penetrated through the hole. He observed carefully for a while and found that there was no danger. Then he carefully stretched into his head from the broken hole. The inside of this lime cave is very wide, about twenty meters high, and the internal area is about the same size as the school hall. Many stalactite pillars inside it were broken and broken for some reason.

Ling Li's eyes carefully swept through the cave, and suddenly stopped near the rock wall to the left in the cave. There, there was a huge beast bone that was more than 20 meters long and three meters high!

Such a huge skeleton is the largest terrestrial animal that Ling Li has ever seen in memory, and is even twice as big as the mutated giant elephant. It seems to be similar to the extinct Tyrannosaurus dinosaur on the Blue Star in memory. Although this is just a corpse, Ling Li can still feel the terrifying aura emitted from the skeleton. No wonder there are few rats in this tunnel. I'm afraid that they ran away because of this aura.

The beasts are indeed much better than humans for the perception of danger.

This should be a powerful alien beast or a star beast skeleton. I just don’t know how such a powerful creature died in this lime cave.

This confusing problem is difficult to understand. Ling Li observed it carefully for a while and confirmed that there was no danger. Then he picked up the mine pickaxe and chiseled the hole bigger, allowing a person to drill through the middle. He put down the mine pickaxe in his hand, turned back into the tunnel, turned off the lit mine lamp, put it in the basket, and then took it into the hole he dug out.

After packing up his things, Ling Li took a deep breath, stabilized his mood, held his breath, and listened to the movements in the tunnel. Seeing that there was no accident and everything was normal, he began to get up and climb into the rock cave along the broken hole.

Ling Li came to the cave, walked to the huge skeleton of an unknown beast, and observed it carefully.

"Dou, I found that the host was concentrating on observing a certain animal skeleton. Did it consume 1 point of energy for analysis and detection?"

Ling Li now has more than 100 points of energy and is a little rich, so he chose this time without much hesitation.

So the system quickly popped up a dialog box:

The skeleton of the seventh-level star beast underage ancient demon dragon crocodile.

｛Note: The flesh and blood energy has dissipated, and some of the powerful energy that was alive (absorbable) are still preserved in the bones. There is a star beast crystal nucleus in the skull of the head. Due to poor preservation, about one-sixth of the energy dissipated (absorbable)｝

There is actually energy absorbable in this beast bone?!
