"That's ...... Pyramid? ”

Lin Yue looked at the pyramid-like buildings on the ground that reflected a faint white light in the moonlight, and was in a trance for a moment.

When did I enter the secret realm?

How did the pyramids appear in another world?

But soon as Xiaobai landed directly on one of the "pyramids", Lin Yue knew what these things were.

These are huge mountains of stone, coal, and iron!

Coming down from this hill about fifty meters high again, Lin Yue also saw the robot dog that was still working.

"Good fellow, this is too diligent." Lin Yue looked at the one beside him, and then looked at the four next to him, and he was already impressed by these little metal guys.

This is worth it from day to night, consume until the power is almost out and then rest, and then get up at dawn to bask in the sun and continue to dry?

Unknowingly, Lin Yue, an exploitation capitalist who let the robot dogs enjoy the blessing of going to work 24 hours a day, is reviewing the fruits of their labor at the moment, and after confirming that their operating temperature is not high, and there is about 90% of the power, he intimately replenished some magazines for them.

Turn it off? Impossible.

Unless it really breaks down one day, they can do significantly more with their own charging and free distribution of power working hours.

In the current situation of a relative lack of resources in all aspects, it is impossible for Lin Yue to let them stop like this, even if the stones and iron blocks of these five "pyramids" are already a considerable reserve.

Having said that, not long after he came down, Lin Yue felt that there were waves of heat coming from all directions, which made people quite uncomfortable.

"This weather is really uncomfortable."

The sound of machinery running sounded, and Lin Yue saw that two more robot dogs had transported out the ore.

Their circular camera turned to look at it, and after carefully observing Lin Yue and Xiaobai, it was driven again, moving farther away to the stone mountain again, and putting the stone on the mechanical arm to the side.

Eventually, they descended back into the pit, moving quite quickly, without seeing a hint of slowness or jamming.

"The efficiency is really good, and it seems that I really did nothing wrong." The robot dog is extremely efficient, and even at this night, it continues to work, indeed, I don't know how much more efficient than his own.

Lin Yue descended into the pit, and then walked inward through the passage that had become much wider.

The temperature dropped all of a sudden, but it was still quite uncomfortable.

The sound of tinkling metal and rock knocking inside kept coming, and under the light of the flashlight, Lin Yue suddenly found that he had entered an extremely huge space!

"This scale...... You're almost on the saltpeter mine, right? ”

Looking at the bottomless underground pit that was much wider than before, Lin Yue couldn't help but marvel!

The original pit has now become an "entrance", and the space below and around it has become extremely deep and wide!

Moreover, Lin Yue also found that when the light of the flashlight flashed in the center of the entire mine, it even provoked a burst of reflection!

Reflective? So what?

"Quack." Xiaobai saw that the master wanted to go down, and signaled that it must be carried by it, the hole in the ground was already quite deep, and it was probably not possible to go down like that.

Lin Yue was picked up by Xiaobai and quickly circled down.

He found that it seemed that he had really thought a little simple just now, and this depth was probably nearly 100 meters!

After a while, they finally landed on the ground, and the two robot dogs that were mining came over, and found that it was Lin Yue and Xiaobai, and then returned to work to continue to knock.

Lin Yue looked around at the wide and deep passage around him, and really couldn't imagine that it was knocked out by two robot dogs.

He walked over to the reflective spot he had observed earlier, and found out what it was!

"It's ...... Crystal? Lin Yue found that the huge transparent or translucent purple and white prisms stacked in the center of this place were not crystals.

He used the system to identify it, and found that there were some small other minerals in it, such as malachite or something, but the amount was quite small.

Lin Yue searched around a little, and found that there was a hole in a corner that was more than one meter high and more than three meters wide.

The light of the flashlight flashed, and Lin Yue quickly confirmed that this was a crystal cave, and it was extremely deep inside, and he didn't know how much space there was inside.

If the robot dog falls in...... I guess it's going to be hard to get out on your own.

Lin Yue got all the two robot dogs, and then reset them to rule out the option of mining crystals.

When finding the right direction of use, he did not need such ornaments.

After pocketing all the crystals in the center of the cave, Lin Yue asked Xiaobai to bring him back to the surface and came to the front of the pyramids again.

"It's useless to take the crystals back, it's better to build a shelter and collect them first." Lin Yue immediately used 4 evacuation plan drawings and immediately set up a "warehouse" on the ground.

Large warehouses are obviously better, but there is really no alloy on hand, so you have to use extra shelter blueprints for storage.

Wait until the alloy is enough, and then it's not too late to build it.

After putting all the crystals into it, Lin Yue also came to a "pyramid" and quickly began to carry it.

However, at this moment, Lin Yue suddenly heard a fierce gunshot, and at the same time, there were bursts of screams!

Lin Yue was instantly ready for battle, but at this time, the gunfire stopped, and the two patrolling robot dogs circled back again and walked around beside him.

"Quack." Xiaobai signaled that Lin Yue's enemy had run away, and took him to the place of the incident.

A lizardman's corpse lay there, not a single panting.

He also discovered that there was a deep hole in the vicinity that seemed to be where the lizardmen had come out.

The noise faded away and then eventually died down, and the remaining lizardmen did all run away.

Are these guys hot and can't stand coming out?

Filling the storage space, Lin Yue asked Xiaobai to take him back immediately and returned to the outside of the shelter.

"Xiaobai, you go back to the shelter and rest for a while, it's too hot outside."

The temperature feels like it's not much different from the daytime, it seems to be rising, and if there is nothing in the shelter that can exhaust the wind, it is estimated that people can suffocate in it when they fall asleep.

Extreme heat ...... The real horror of this catastrophe lies in this.

Inside the shelter, it is even more stuffy and uncomfortable when the windows and doors are closed, and it is further exacerbated at night.

But if you open the window and open the door......

The mutated creatures outside will be able to eat.
