Lin Yue and Xiaobai took the elevator from below to the small station about 20 meters above the ground, got off the elevator, and looked at the brand-new train.

"Who would have thought that you could ride such a thing in this other world?"

Although there are only two carriages, it is spacious enough for him.

Moreover, he didn't need to do any complicated operations on the cab side, and after installing an automatic, he could basically hand it over to the automatic.

"Xiaobai, speaking of which, you haven't been in a car yet, have you?" Lin Yue sat on the stool on the side, spread a large sheepskin cushion directly in the corridor, and asked Xiaobai, who had been looking out the window.

"Quack...... Xiao Bai didn't seem to understand why the owner had brought it to this large metal box.

"Haha, it seems that you don't understand how this is played, so ......" Lin Yue walked to the cab and clicked a few times on the automatic.

Speed 80 km/h, constant speed.

Soon, with the roar of machinery, this metal box, which was just a "metal box for not knowing what to use" for Xiaobai, gradually began to operate, and slowly began to move forward.

"Quack?" Xiaobai didn't seem to understand what was going on, but he saw the scenery outside the window begin to recede.

"Xiaobai, sit tight!"

The train gradually began to speed up, and with a burst, rhythmic "clang" sound came, the original fastest update please browser input-

There is some bleak and lonely beauty.

Lin Yue looked out of the small car window for a while, and suddenly thought of something.

Mutant Creature ...... Will they come and attack the track and the viaduct?

Especially at night?

Lin Yue thought about it for a while, and decided that when he went back, he would appropriately use the sweat and blood of the lizardmen to make a small transformation of the entire track, so that at least it would not suffer any damage from the mutated creatures.

Also, be sure to watch out for lizardmen......

Do you want to get some medium-sized electric sentry machine gun mounts for the sides of the viaduct? Or is it appropriate to put a robot dog?

However, no matter which one you have, you need a lot of it......

Lin Yue felt that this aspect seemed to need further thinking, and as for other aspects, it was as he had just thought.

Having made up his mind, Lin Yue decided to give this train another transformation when he turned back.

The train sped away, and it took less than half an hour to reach the final station.

And here, right now, is the western side of the outer walled fortress of the saltpeter mine.

Two days ago, when Lin Yue asked Xiaobai to come over to deliver food, he had already asked him to tell the black dot and the green claw to open to traffic, don't be frightened by this sudden appearance or come over out of curiosity.

Therefore, after the train arrived smoothly, Lin Yue did not see the little ones coming over because of this.

After getting off the train, Lin Yue directly took Xiaobai, who had not yet recovered his senses, from the station to the wall, and then went down the descending steps directly to the mine.

At this moment, this huge saltpeter mine has now been excavated into an extremely shocking pit by the robot dogs.

"Quack!" "Quack!"

The two little guys, Black Dots and Green Claw, immediately led the little Xiaoice lizards to accept Lin Yue's visit, and they stood in three rows together, like soldiers waiting for the review!

Lin Yue looked at the black dots and green claws that seemed to be stronger and more powerful than before, and nodded with satisfaction.

They are quite conscientious in their station, and even if the saltpeter mines have been attacked by dozens of lizardmen in the recent past, they have not taken any advantage from them.

On the contrary, the lizardmen left behind tens of thousands of corpses, allowing the little ones to get quite a lot of practical training.

That's a lot more than even the little guys in the natural sulphur ore mountain base and the oil river base combined.

If anyone in the next wave of Xiaoice lizards can evolve again, Lin Yue feels that the little guys here will probably be the first wave.

Even, the black dots and green claws may have a secondary evolution.

However, having said that, Lin Yue felt that this saltpeter mine was probably also a mineral that was quite needed and extremely scarce for the lizardmen, even more urgent than natural sulfur and oil.

Otherwise, they wouldn't have organized a large-scale attack like this, would they?

Moreover, if you think about it carefully, the number of lizardmen and the fortifications built on the side of the natural sulfur ore mountain are very different from those on the saltpeter mine!

There are only about a hundred natural sulfur ore lizardmen, and most of the rest are beggars.

And here, when I first came to attack, there were nearly 10,000 lizardmen and nearly 1,000 survivors!

That's enough to illustrate the problem.

Lizard people, I'm afraid I haven't found a source that can replace the saltpeter mine here!

Thinking of this, Lin Yue felt that it was quite a wise and correct choice for him to be able to connect this short- and medium-distance track-type express train here first.

After that, he could indeed increase or decrease the number of Xiaoice lizard guards in various places in time according to the situation of several sub-bases.

"Little ones, how about eating something good and then going back to the main sanctuary for a good rest?"

Lin Yue took out a large number of delicious foods, which were steaming hot and fragrant, deeply attracting the attention of this group of little guys who could only eat cold things.

And when they heard that they could go back, they all began to jump up and down again, as if they had been looking forward to it for a long time.

Soon, in the gobbling up of the little guys, Lin Yue took Xiaobai to the inside of the mining field.

The mining of stone has accumulated a considerable amount in three days, and it seems that as the further the digging goes, the more the rock becomes, and the mining of gold gradually gains some scale and production.

Lin Yue stored a large amount of saltpeter ore in a large underground warehouse nearby, and did not take it away, these things are actually not his usual things, there are still a lot of stocks on the main shelter, enough for him to use for a while, so he will store here for the time being, and when the other survivors begin to need gunpowder, he can face it with enough production at that time.

This time, Lin Yue's main purpose was gold and stone.

Stone for road construction, and gold for ......

Lin Yue now, in fact, has an idea.

Bartering in another world is actually quite inconvenient.

A lot of things are not equivalent, although, a lot of the time, bartering is really convenient, but more often than not, chaos is also really messy.

If there is a standard for purchasing money as a unit in imitation of the earth, can the market be regulated?

Now, there is a very mature barter world trading channel in this system, whether it needs currency to transform it, Lin Yue doesn't have much confidence now.

For now, this is just an idea of his.

There are no mints, and among all kinds of precious metals, only the current reserves of gold are okay, and there are some copper.

Silver...... It's too little, and platinum is only the size of a few boxes.

Not enough.

The gold is only less than a hundred tons, and Lin Yue feels that there is still a long way to go.

"It's hard at first, but it's time to think more and think more."

Killing a mythical beast will allow humanity to completely empty a city of secret creatures.

And now in the secret realm, how many mythical beasts there are, Lin Yue is not clear.

He just knows that if he wants to do something, he has to accumulate a lot.

Moreover, the mythical beasts must be destroyed one by one.

The last time he fought the Mythical Behemoth, he had accumulated quite a bit of experience, and since then, he has indeed built quite a few cluster bombs and stored them in the storage space.

In case he went to the secret realm to explore and met that kind of big guy again, Lin Yue really wanted to kill that one more.

Clear an area of the secret beasts, and you can also get a palladium treasure chest, why not?

Lin Yue put a large amount of mined gold and stone into the storage space and stuffed it to the brim, and then refilled the bullets for the robot dogs stationed here, as did the magazine of the medium-sized electric sentry machine gun station.

Then he returned to the Black Dots and the Green Paws, and the little ones, who were lying on their backs on the ground, with bulging bellies, were a little overwhelmed.

"Let's go, let's go back to the Lord's Shelter, and we have to let you rotate your shifts, go back and enjoy yourself."

As soon as the little ones heard that they were going back, each of them struggled to get up, and followed Lin Yue to the train.

The train slowly drove out, and Xiaobai was more accustomed this time, this time he directly lay on the sheepskin mat on the ground and yawned, while the other little ones were bouncing in the carriage, extremely excited.

"It's like a little kid, Xiaobai, how happy are you?" Lin Yue looked at the still blood-red grassland outside the window and couldn't help but say.

"Quack." Xiaobai nodded, and then lay on his stomach and thought.

The world is changing too fast.

It looked at the Xiaoice lizards, then at the black dots and green claws.

Raising his head, Xiao Bai looked at the blood-red grassland speeding by outside.

It remembered itself when it was a Xiaoice lizard, and it seemed a long, long time ago

Like.

Although, actually, not for long.

Every day, with the master, he came out of that small shelter to hunt and fight, harvesting treasure chests one after another, and fighting the mutant sheep and tabby shadow deer that were still strong for him at that time.

After experiencing the bitter cold and surviving the disaster, it evolved into a more combative little guy.

Later, the owner's shelter also became larger and more spacious, and the owner became more powerful.

Later, the master had a strange illness, and it evolved again and saved the master. And when it reached the secret realm, it entered the stage of molting and could not fight, and the master also saved it.

After that, the master and it together, met Xiao Meng, the combat power became more terrifying again, and the shelter, also became more and more huge, after countless battles, one by one sub-bases were built, the master just now, and made this without it flying, you can also quickly move to the saltpeter sub-base of the convenient tool.

Xiaobai even felt that this was faster and more stable than it was flying.

Little by little, the owner is getting stronger, and it feels like it's getting stronger.

However, the master did not belong to this world in the first place.

It belongs to the world on the other side of the Ancient Gate of the Secret Realm.

Moreover, because the ability to heal itself will fail in the secret realm, the excited appearance of the master has never been seen by Xiaobai.

It knew that its master might one day return to that world.

But how will it be?

And Xiao Meng and they continue to live on this land?

Or go with your master to a world that doesn't belong to you?

Xiaobai's incomparably complex brain, at this moment, is exactly the same as that of a human being.

Its ability to learn, as well as its ability to receive, is not much different from that of its master.

The more it thinks, the more complex it thinks.

Xiaobai looked at the Xiaoice lizards again, then at the black dots and green claws, and finally, his eyes fell on the master.

Again.

It opened its mouth and yawned.

Long yawn.

Thinking is mentally and physically demanding.

Xiaobai closed his eyes, and he felt extremely sleepy.

And, for some reason, it always felt like it couldn't exert its strength.

In a trance, it heard its owner constantly calling its name.

However, it could not open its eyes anyway, and just fell into a deep sleep.
