The car kept moving forward on the gray-white road made of stones.

When it comes to road construction, although Lin Yue cannot guarantee that he is the first, he is definitely the one who has built the longest mileage.

Although asphalt roads are smoother and more beautiful, their shortcomings are indeed fatal.

In this extremely hot weather, the strong sunlight has also brought it close to the melting point. If you continue to drive on it, it is likely to destroy the smooth road surface, leading to various possible problems.

Therefore, Lin Yue chose not to lay asphalt roads anymore.

He is not in the advanced stage of obsessive-compulsive disorder, and it is not unacceptable for the pure stone road to continue onto the original asphalt road.

Moreover, there is actually a bug in the road paving thing that can be exploited, that is, it is constantly broken down into design drawings. Just like last time, he directly produced the design drawings of ten kilometers of asphalt roads at most. If there are enough materials, these ten kilometers

He can further change it to twenty kilometers, forty kilometers, or one hundred kilometers!

Naturally, this can also become his main support for infrastructure construction in the future.

As his resource points continue to increase, and as his territory expands, the importance of roads will become more and more prominent.

He doesn't care what other survivors think of this road, nor what lizard people and beggars think of him, but if anyone wants to destroy the road or set up obstacles for him.

Then the outcome is very simple.

The lizardmen left treasure chests, and the survivors left storage space.

Lin Yue felt that there was no need to reason with unreasonable people. If only he was left alive at the scene, the matter would be solved perfectly.

The stone road kept being paved, and Lin Yue kept driving forward. The distance from the Berg mine to the saltpeter mine was only more than ten kilometers, and the road was quickly paved.

When leaving the Berg Ore Mountain, he did not forget to lay out a small solar power generation kit and socket, and also programmed the robot dogs one by one to charge during their free time.

In this way, they can really work 24 hours a day, and the efficiency of collecting ore can also be higher!

Before the disaster officially arrives, the robot dogs cannot have a good rest.

Having said that, 30 stones can be used to lay a five-meter-wide road, which is actually quite expensive. However, the number of stones he has is really unimaginable. The total number of stones dug out by the robot dogs working day and night is enough for him to lay the road.

This road can even go further.

Xiaomeng smelled his master's scent early. He excitedly pushed the huge rock away from the gap in the wall and fortress, and excitedly walked around the master's car with Black Spot, Green Claw and other little ice lizards.

.

"Thank you for your hard work these two days!" Lin Yue took out the lion-headed bear steak to reward these friends who had persisted in the difficult post for two days.

"Ouch!" Xiao Meng was particularly excited. The weather was really bad, so bad.

It and other little ice lizards had to dig a small cave with the help of the robot dog to escape the torture of high temperature and heat.

In the past two days, except for the hundreds of lizardmen who attacked them in the morning of the first day, everything has been calm since then.

Those hundreds of lizardmen didn't even have time to let them take action, and those robot dogs took care of them all.

Xiaomeng felt depressed about this, but they were quite impressed when they saw the capable robot dogs continuously mining the huge saltpeter mines and stacking them behind hills like mountains of ore.

However, the boring life and the hot weather made them miss the life in the shelter even more. Since the last time Xiaobai came to deliver food, they have been waiting for the owner to arrive so that they can take them back.

.

Lin Yue did think so too.

Take the little ice lizards and Xiao Meng back to the shelter, don't let them continue to suffer here.

Arriving at a stone platform left by the lizard man before, Lin Yue took out a high-precision research workbench and touched the two.

[You have obtained the stone watchtower design drawing!]

Okay, now it can be set up in the shelter, but he doesn't need a watchtower. This thing is more suitable for use as the base of a medium-sized electric sentry machine gun platform.

It's not that he can't build this thing, it's because there is such a thing here and he doesn't need to bother to study it himself.

Then, Lin Yue started collecting non-stop.

[You have obtained the shelter design drawing x1]

[You have obtained the shelter design drawing x1]

【You got...】

The system beeps continuously.

Lin Yue was like an emotionless collecting machine, constantly turning the remaining shelters on this saltpeter mine into blueprints and storing them in storage spaces.

Lizardmen and beggars gathered here in large numbers before, leaving quite a few shelters behind. These shelters also became one of his trophies after the Saltpeter Mine Battle.

It's just that he left in a hurry last time and didn't completely pocket them. Now that he's here this time, there's no need to be polite.

It didn't take long for him to collect all the 167 shelter design drawings!

The reason why there were only so many left, he thought, was because some of the beggars who escaped when he attacked the inside of the saltpeter mine had collected a lot.

Otherwise, there should be quite a few more.

After doing this, there is really nothing noteworthy about the saltpeter mine for the time being. From his own personal experiences and chats on the World Channel, he can get some valuable information - the lizards and beggars are all

Constantly migrating.

After the extremely hot temperature affected the underground ruins, they couldn't bear it, so they emerged from the ground and migrated in groups towards the mountains.

Whether it's saltpeter mines or natural sulfur ore mountains, I guess I don't have any power to get involved.

However, Lin Yue was also curious as to why the lizardmen didn't go through the ancient gates of the secret realm to reach the secret realm. They should be existences that would not be affected by the rules of the system, right?

The system will kick out all survivors and beggars from the secret realm the day before the disaster, but there is no way to kick out the lizardmen even if it stops.

Could it be that they are also affected?

There is currently no evidence of this, and Lin Yue has no way of knowing whether this is actually the case.

After all, if it is not affected by the system, according to his understanding, the secret realm should be the lizard man's first choice.

The six-headed robot dogs in the storage space are also set up to be responsible for the guards and sentries here.

Although there are a large number of robot dogs here, he had previously set them all in mining mode, and would only start fighting when faced with a crisis.

Lin Yue placed a medium-sized electric sentry machine gun platform above the gap in the walled fortress. The width here would not hinder it at all.

After that, he immediately connected the wires to the two small solar power sets and successfully connected them completely!

Soon, the medium-sized electric sentry machine gun station flashed with light, and Lin Yue also recorded the images of himself, Xiao Meng, Xiao Ice Lizards, and the robot dogs through its own recognition camera.

Of course, he has also set up automatic idle charging mode for all the robot dogs here, and reset their special mining programs.

After doing this, the defense of the mine has been completely prepared.

At least there shouldn't be any problems until disaster strikes.

"Xiao Meng, can you run back?"

After the other little ice lizards got on the bus, Lin Yue discovered again that he had no way to get Xiao Meng to sit on the bus.

This "little guy" looks like it weighs at least a ton, maybe even heavier. His small car is really not big enough for it.

It seems that we still have to go to the secret place and look for trucks and the like from there.

But having said that, this hot weather is a bit too much... It's not even noon yet, and I feel like I'm almost sunburned. The body temperature alone is probably already over 40.

I touched the seat cushion of the car seat and found that it was extremely hot. There would definitely be no problem in getting a breakfast of bacon and eggs on it.

Hurry back to the shelter, the outside is no longer suitable for survival.

Everything in front of him was tanned almost white like a saltpeter mine. The only thing that made him feel normal was the forest that had been burned to char.

How long will this damn weather last?

Forget it, one day today, one day tomorrow... Good guy, it will really start tomorrow night?

With an air-conditioned room, watermelon and ice cubes to keep him alive, Lin Yue didn't feel too uncomfortable. He just felt uncomfortable for a while when he went out to collect supplies.

He was easy to talk to, but other survivors would probably have a hard time getting through it.

Fei Yue found something that could generate electricity, and with the help of his air conditioner, he was able to live a life that at least would not kill him from the heat, but what about the others?

In fact, you only need to do one thing to avoid giant hailstones and fire tornadoes - build a sturdy basement.

But that is without the condition of "extreme heat".

If you can overcome this, you can simply get through this, which can be said to be the most difficult disaster since the beginning.

To be honest, Lin Yue also wanted to help all the survivors in this world to the best of his ability, and he really didn't want to see that he was the only human being in this other world.

But, this time, so far, there really is no clue.

The prerequisite for supplying and manufacturing air conditioners in large quantities is that all mankind has access to electricity, and this hurdle alone cannot be overcome.

Where is it easy to find power generation equipment?

Solar power generators, or diesel and gasoline generators, these things are hidden in various places that may appear in the secret realm.

But if you're not lucky, you won't be able to find it at all.

Even if you find it, you still have to consider the consumption of diesel and gasoline.

After calculating this, even if he produced countless air conditioners, they would still be useless.

There is no even the most basic electricity.

Lin Yue shook his head and signaled to the little ice lizards and Xiao Meng that it was time to leave. He took some saltpeter and there was no point in staying here any longer.

After that, he only needs to come again tomorrow to collect the saltpeter and robot dog here.

"Oooh..." Under the fierce sunshine, Xiao Meng was also a little wilted, and he seemed a little thirsty at this time.

"I want to drink water, wait a minute." Lin Yue forgot that he hadn't given them food yet. He had smelled a bad smell in the mine before, and it was probably because the food had spoiled.

He took out a large basin and poured water from a 4L mineral water bottle into it. The little ice lizards jumped in and gathered around the basin. It seemed that they were all thirsty.

However, Lin Yue discovered that they did not drink it immediately, but sprayed out streams of extremely cold mist into the basin!

The water cooled down quickly, and soon after it became icy, they drank happily.

Good guy, can you use ice water to resist the hot weather and cool down your body? It’s really...

etc.

ice!

Lin Yue slapped his head suddenly! Yes, there is ice!

Isn’t ice a pretty good way to get rid of the heat? Why didn’t you think of it earlier?

Putting ice in water can reduce the temperature, and even if it melts there, it can continue to lower the room temperature!

If a large amount of ice could be produced, wouldn't it be possible for the survivors to escape the disaster of this extremely hot weather?

The little ice lizards, the little white ones and the little fierce ones can all emit extremely cold spray. If possible, make ice...

No, no.

Even if Xiaobai and the others vomit blood to make ice, they will definitely not be able to supply even one thousandth of the two billion people.

There is no other way to make ice quickly in this world, there is no refrigerator, and there is no cold storage.

How do modern people make ice when there is no electricity at all? What method do they use?

Lin Yue felt that he could give up this idea. If those people really couldn't bear it, there was nothing they could do. He didn't have magic or anything to create so much ice.

"Let's go, let's go back quickly, Xiaobai and the others should be waiting in a hurry."

Xiaomeng let out a low growl, stomped on the ground and ran towards the shelter quickly. He also started the car, stepped on the accelerator, and took one last look at the saltpeter mine.

The robot dogs mined a huge amount of ore and piled up nearly a hundred saltpeter mountains nearly twenty meters high. If they were to take them all back, they would probably have to go back and forth several times.

He can't use so much to make various explosives, and the role of saltpeter ore seems to be to make explosives and ice...

Making ice?

Make ice!!

Lin Yue felt like a flash of thunder flashed in his mind!

Good guy, I actually forgot about this!

He felt that his brain was almost in a state of numbness due to fighting too many lizardmen recently, and he almost forgot about making ice with saltpeter!

Using saltpeter to make ice, isn't this the best way to solve the problem of extreme heat disasters?

The method of making ice from saltpeter was something he had seen in the experimental class of the chemistry interest group in high school.

He had forgotten the specific method, but his teacher had said at that time that the saltpeter ice making method was the most widely used method discovered by the ancients that could make ice cubes free even in summer!

Then, the teacher actually made a basin of ice using saltpeter!

At that time, this had a great impact on Lin Yue. After that experimental class, he secretly asked his teacher for saltpeter, but he was rejected because of the danger of saltpeter.

"It seems to be verified that if it is really possible, then surviving the disaster this time will not be a problem!"

Lin Yue's heart began to beat rapidly.
Chapter completed!
