Bang!

It was pitch black around.

"Ding--"

Lin Chen took out the communication device from his pocket, and the pop-up blue window made the darkness light a little bit, and at this time he clicked on the lighting function. The lit white beam of light gradually brightened the dark hole.

The cave was not wide, but a little narrow. Lin Chen bent his body and held the communication instrument in his left hand to illuminate the light, and the purple spear in his right hand, and walked carefully inside.

At the same time, he took out the right-eye sensor from the space-time bracelet.

"Ding--"

As his eyes swept through the hole around the ground, the holographic window popped up in his right eye was green.

Hazard index: 0.

However, there was a detection distance of 10 kilometers on the plain, but now it is only a few hundred meters in this cave. Obviously, the sensor cannot pass through this narrow cave.

Lin Chen was not surprised but happy when he saw this scene. He knew that the limitations of the sensor, mountains, cities, crystals, etc. would limit the sensor. If it were just a cave, it would not be possible to limit the distance of the sensor so seriously. The only thing left was crystals!

There is indeed a mine!

"Da da!"

Lin Chen was even more excited. The fire crystal stone mine that was discovered in the crystal boundary last time was occupied by Zhou and Bai's family. Although he stole some of the intermediate fire crystal stones, he was still buried in the forest area at the connection point of Qiuyang City.

And this time he has a space-time bracelet, no matter how many he can hold it!

Moreover, he remembered that the earth crystal ore here was no smaller than the fire crystal ore in the Red Flame Crystal Armor Beast Cave.

With excitement, Lin Chen accelerated his pace and walked along the winding and narrow hole for nearly five minutes, and finally the vision ahead became wider.

Under the illumination of the communication instrument, there is an empty cave in sight. The surrounding cave walls are not rocks, but all of them are soil. If such a large cave had no earth crystal mine, it might have collapsed long ago.

The shape of the entire hole is a bit similar to the shape of a gourd. The entrance becomes more and more spacious after entering, and there are several smaller holes on both sides.

Through the sensor Lin Chen, his right eye found many crystal-shining golden light spots around him.

That's right here!

Lin Chen put away the sensor with excitement and prepared to enter the first hole first, but as he walked towards him step by step, he was stunned!

Because there are many tools to dig holes next to the entrance of the hole.

Wait for this...how can there be tools? Someone has come here??

And with his sight, he saw that the earth crystals embedded in the soil in the first cave were all gone, and the tiny golden light spots were emitted from the earth ore veins.

It is obvious that the earth crystal has long disappeared. The sesame-sized golden light spots recondensed on the ore veins are the prototypes of the earth crystal, but it will take at least a few decades to form a new earth crystal.

The crystal boundary has been around for decades, and the earth has been more than 100 years. This is why many forces ignore the remaining mineral veins after mining crystals. Because it has been too long, who knows what changes will happen to humans in more than a hundred years.

"Damn it...had someone finished mining again?"

"Ah..." Lin Chen suddenly had a bolt from the blue and was completely lost. What about playing with me? He worked hard to kill the crystal beast for two days, but he ran in... The mine was still gone in the crystal stone...

He quickly walked into the other holes inside.

The second one was also mined, and the third one...

Why is this happening? Lin Chentm is going crazy. He thought he was going to get rich, but he didn't expect it would be...

The school’s time and space gate was only opened two months ago, right? Usually, students or tutors of senior classes are used by them. Is it because the school mined?

Or did an outsider enter the crystal boundary from other time and space gates and then discover it in this forest area?

Just when Lin Chen felt that he was about to go crazy, he came to the last hole and was stunned again!

The earth crystals on the ore vein in front of me seem to have been mined recently, so they did not condense golden light spots. However, these are not the key points. The key points are that there are many half-fist-sized crystals inlaid on the innermost ore vein!

The earth crystals like golden gemstones are dazzling. At first glance, the number is about 100 yuan.

"Hey, do I... Is there still more than 100 yuan left?"

Lin Chen's originally gray face suddenly appeared again in surprise and rushed in excitedly.

"Wow...Who is so good? I left more than 100 yuan for me?"

Although low-level crystals are not as good as intermediate crystals, each piece can be sold for about 10,000 yuan. These earth crystals should be sold for more than 1 million yuan together, which is the money of a mecha car.

He remembered that the uncle named Nan in the crystal boundary last time had a blue mecha car. It was really fast to escape from the crystal boundary, so if there was a mecha car, the danger would be much lower in the crystal boundary.

"But... this isn't the school crystal mine, right? Otherwise, why is the time difference between these holes being mined so big?"

Although Lin Chen was excited, he still guessed that it was the school's resource through the time when these holes were mined one after another.

Otherwise, if outsiders or students' instructors, the earth crystals here should have been mined long ago.

"It's okay, since the time and space gate has been open for two months, how can the school know who it is?"

Thinking of this, Lin Chen quickly took action to mine the remaining crystals one by one and received them in the space-time bracelet.

The space inside the space-time bracelet is 9x9x9 meters in three-dimensional space, so it can be installed with a mecha car, and it is naturally no problem to install this earth crystal.

“1…30…99…118 yuan!”

The money for the mecha car is available!

...

More than half an hour later, Lin Chen looked at the remaining mineral veins, then clapped his hands and walked out with satisfaction.

Although he felt a little painful, fortunately he had gained something, so he was in a big ups and downs, which was pretty good.

Climbing out of the cave, Lin Chen plucked the grass around him again, confirming that the cave was completely blocked, and then left quietly.

Then he went west along the mountains. Just as he was about to go back to the junction of the 2nd area of ​​Class 9, Lin Chen suddenly found that more than 60 students in Class 9 were missing! Moreover, the students in Class 2 also retreated from the 28-kilometer area to about 25 kilometers. If he hadn't activated the nerve sensing in advance and walked rashly like this, he might have really broken into the 2nd team resting.

What's going on? It's less than an hour since I came in? What happened when the two students in the middle of the night didn't sleep?

Lin Chen felt it was very strange, so he quickly took out his sensor.

He plans to see what the situation is like when he gets off class 2 and 9. There are also the situation of class 1, 3, and class 4 Wu Feng and others in the west.

"Ding--"

Soon all the surrounding situation appeared in his senses.

First of all, the last two classes, with more than 70 students in their entire class, and at some point they were divided into three teams. By casting a net, they were searching for something from the 25-kilometer area to the east and the south.

The crystal beasts here have been cleaned up, and it is obvious that they are looking for their own group.

Because I didn't guard it at 28 kilometers, I retreated to 25 kilometers and then scattered, so I had to find my own group?

Lin Chen was a little surprised. Didn’t he just steal some crystal beasts? Is there such a big grudge?

But it’s true that the method of Class 2 can really find a place where Yue Jing and others rest. The distance between 25 kilometers and 22 kilometers is only 3 kilometers. All the more than 70 people are scattered. Some of the teams searching south are likely to find them in searching east.

"It seems that we have to find a way to go back and notify Yue Jing and the others!" Lin Chen's face was a little serious.

As his eyes shifted and when he looked to the west, he found that more than 60 people in Class 9 had passed through Class 1 and rushed to the area of ​​Class 3.

However, the students from Class 1 and Class 3 did not know where they went, and no students from these two classes were found in the area.

The limit distance of his sensor is 9.5 kilometers, so he can only detect the range of 3 shifts at most. Then there is 4 shifts west (left) and the distance is not enough.

So Lin Chen frowned and then took the sensor directly, bypassed the students in Class 2, and drove west for 3 kilometers.

This time, the area of ​​Class 4 finally sensed it, and he also discovered the movements of the students in Class 1 and Class 3.

"I'll go... these 1 and 3 classes actually ran to our 4th area?"

"And... Wu Feng and Liu Yu and the others... seem a bit miserable!"

"Not only were the two squads surrounded in the middle, but even the crystal weapons in their hands were taken away..."

When he saw this through the sensor, he looked speechless.
Chapter completed!
