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

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

"Haven't you already completed your quota?" A few people had just handed in the task, and the little girl with a round face seemed to remember Ling Li, and asked a little strangely.

"I like mining, and I want to mine more when there are fewer people." Ling Li grinned.

"Hehe, you can't make much money from mining." The little girl also smiled, finished registering for Ling Li in her hand, and returned her student ID, "Choose the tools yourself." ”

Ling Li nodded, came to the site where the ore was stored on the side of the wooden house, picked a pickaxe, and then casually found someone to carry the basket on his back, and walked towards the pit he had explored yesterday afternoon.

There are a few more students coming to mine today than yesterday, and most of them are still working in the tunnels without completing their tasks. Ling Li held a mining lamp in his hand and walked along the tunnel, and the sound of mining pickaxes hitting the ore came from the tunnel.

Passing by some of the students who were mining, they didn't know each other, so no one said hello. Only occasionally some people will look at him strangely, maybe they can't figure out why this person is also mining in the tunnel.

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

As he continued to go deeper, there was no longer a sound coming from ahead, and Ling Li followed the mark he had made on the rock wall yesterday, turning around. Since there was no longer a probe, this time the speed was much faster, and after only walking for about half an hour, I came to the end of the tunnel where I had dug the source energy spar yesterday.

Ling Li thought about it, but still lit the open flame miner's lamp in his hand, buckled the glass cover, and hung it on the rock wall on the other side. Otherwise, if someone breaks over and finds themselves digging ore veins in the dark, they must not scare others half to death as a ghost!

He glanced behind him again, and after confirming that there should be no one within more than two hundred meters, he took a deep breath, leaned out half of his body, stretched out his left palm, and pressed it against the rock wall inside.

"Drop, zero .8 meters in front of the right found that it can absorb energy, do you absorb it?"

"Drop, one point four meters in front of the right found that it can absorb energy, do you absorb it?"

This time there were two rings again, Ling Li was stunned, could it be that this was the rhythm of preparing to dig a cave for himself?!

The granite on the right is too hard, while the vein edge on the left is better excavated, and the source crystals appear to have formed along the gap between the granite and the iron vein.

Don't worry about these for now, dig out these two source crystals first.

If you bring it back to the city, you can exchange it for a few stacks of bills at any time!

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

An hour later, Ling Li dug out a cave at the end of the iron ore vein that was more than a person high and nearly two meters deep, and only then did he hold the first source energy spar in his hand. This hedron is about the size of a knuckle, about the same as the two pieces I got yesterday combined. Ling Li was overjoyed when he got this spar, carefully put it away, picked up the kettle and drank a few sips of water, and continued to dig with great interest.

When he dug up to the second source crystal, Ling Li found that every time he picked up, there seemed to be an echo, obviously the opposite rock wall was empty, but he didn't expect that he would quickly dig through two tunnels. He didn't think much about it, he simply changed to digging and smashing, and smashed it more than a dozen times in a row, and suddenly there was a bang, and the ore pickaxe had penetrated the stone wall, and a piece of ore that fell fell into the ground, and it actually echoed endlessly, it seemed that there was a large space inside, not a tunnel.

Ling Li felt curious, and stretched his right eye into the hole knocked out by the mining pickaxe to look inside, and found that there was a large lava cave inside, and it turned out to be a different cave.

He suppressed the curiosity in his heart, and carefully dug out the second source energy spar, and after putting it away, he used a mine pickaxe to chisel the hole a little bigger.

At this time, a large hole had been broken in the rock wall, and the head could already be inserted through the hole. He watched carefully for a while, and when he saw that there was no danger, he cautiously reached through the broken hole and reached into his head. The interior of this lava cave is very vast, about 20 meters high, and the internal area is about the size of the school hall, and many stalactite pillars inside it have broken and broken for some reason.

Ling Li's gaze carefully swept over the inside of the cave, and suddenly stopped near the rock wall on the left side of the cave, only to see that there, there was a huge beast bone that was more than twenty meters long and three meters high!

Such a huge skeleton could be regarded as the largest land animal Ling Li had ever seen in his memory, and it was even twice the size of the mutated giant elephant, which seemed to be similar to the extinct Tyrannosaurus dinosaur on the Blue Star in his memory. Although it was just a corpse, Ling Li could still feel the terrifying aura emanating from the skeleton, no wonder there were few rats inside this tunnel, I am afraid that he was frightened by this aura and ran away.

For the perception of danger, beasts are indeed much stronger than humans.

This should be a powerful alien beast or star beast skeleton, but I don't know how this powerful creature could have died in this lava cave.

This kind of confusing question was difficult to figure out, and Ling Li looked carefully for a while to make sure that there was really no danger, and then he picked up the pickaxe again, and chiseled the hole a little bigger, so that a person could drill through the middle. He put down the pickaxe in his hand, turned back to the tunnel, extinguished the lamp, put it in the basket, and took it into the hole he had dug.

After packing up his things, Ling Li took a deep breath, stabilized his emotions, held his breath again, and listened to the movement in the tunnel. Seeing that there were no accidents and that everything was normal, he began to get up and climb along the broken hole into the lava cave.

Ling Li came to the cave, walked over to the huge skeleton of the unknown beast, and took a closer look.

"Duh, I found that the host is contemplating some kind of beast bones, does it consume 1 point of energy for analysis and detection?"

Ling Li now has more than a hundred points of energy, and he is a little rich, so he didn't hesitate to choose yes this time.

A dialog box pops up:

The bones of a seventh-level star beast juvenile ancient demon dragon crocodile.

{Note: The flesh and blood energy has been dissipated, and some of the powerful energy (absorbable) is still preserved in the bones, and there is a star beast crystal nucleus in the skull of the head, and about one-sixth of the energy has escaped due to poor preservation (absorbable)}

There is still absorbable energy in this beast bone?!

Seeing these two words, Ling Li was immediately ecstatic in his heart, and involuntarily stretched out his hands against the beast bone......
