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

In terms of road construction, although Lin Yue couldn't guarantee that he was the first, he was definitely the one with the longest mileage.

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

In this extremely hot weather, the fierce sunlight also brings it close to the melting limit, and if it continues to drive on it, it is likely to destroy the smooth road, causing all kinds of problems that may arise.

Therefore, Lin Yue chose not to lay asphalt roads.

He is not in the late stage of obsessive-compulsive disorder, and it is not unacceptable that the pure stone road continues to the original asphalt road.

Moreover, there is actually a bug in paving that can be used, that is, it is continuously decomposed into design drawings. Just like last time, he directly came up with the design drawings of 10 kilometers of asphalt roads. If there are enough materials, the ten kilometers He can further become twenty kilometers, forty kilometers, hundred kilometers!

This can naturally become the most important help for his future infrastructure construction.

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

He doesn't care what other survivors think about the road, and he doesn't care what the lizard people and beggars think about it, but if anyone wants to destroy the road or set up obstacles for him.

Then the end is very simple.

Lizardmen leave treasure chests, and survivors and beggars leave storage spaces.

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

The stone road was paved continuously, and Lin Yue kept driving forward. The distance from the Berg mine to the saltpeter mine was more than ten kilometers, and the pavement was soon completed.

When he left the Berg Ore Mountain, he did not forget to install a small solar power generation set and socket, and also edited the program for charging the robot dogs one by one in their spare time.

In this way, they can really work 24 hours a day without interruption, and the efficiency of collecting ore can be higher!

Before the disaster officially arrives, the robot dogs can't rest well.

Having said that, it takes 30 pieces of stone to lay a road with a length of five meters, which is actually quite expensive, but the number of stones he has is unimaginable. The total number of digging by the robot dogs working around the clock is enough for him to pave the way. This road can go even further.

Xiaomeng smelled the owner's scent early on. It excitedly pushed the huge rock away from the gap in the walled fortress, and excitedly walked around the owner's car with Black Spot, Green Claw and other little ice lizards. .

"It's been hard work these two days!" Lin Yue took out the lion-headed bear's steak to reward these little friends who had been sticking to the tough positions for two days.

"Goooo!" Xiaomeng was especially excited, the weather was so bad, it was terrible.

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

In the past two days, except for the attack by hundreds of lizardmen on the morning of the first day, they have been calm since then.

The hundreds of lizardmen didn't have time to let them take action, and those robot dogs were all done.

Xiaomeng felt suffocated by this, but after seeing the capable robot dogs continue to mine the ore of the huge saltpeter mine and stack them in the ore mountains like hills, they are quite admired.

However, the boring life and the hot weather made them miss the life in the sanctuary. Since the last time Xiaobai came to deliver food, they have been waiting for the arrival of the master so that they can be picked up. .

Lin Yue really thought so too.

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

Coming to a stone platform left by the lizardmen before, Lin Yue took out a high-precision research workbench and touched the two.

[You have obtained the design drawing of the stone watchtower! 】

Well, it can also be set up on the shelter side, but he doesn't need a watchtower. This thing is more suitable for use as a base for a medium-sized electric sentry machine gun stand.

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

Then, Lin Yue started collecting without stopping.

[You have obtained the design of the shelter X1]

[You have obtained the design of the shelter X1]

【You got... 】

The sound of the system continued to ring.

Lin Yue is like an emotionless collection machine, constantly turning the remaining shelters in this saltpeter mine into blueprints for storage space.

Lizardmen and beggars gathered here in large numbers before, and they also left quite a few shelters, and these shelters also became one of his trophies after the battle of the saltpeter mine.

It's just that he went too hastily last time, and he didn't take them all in. Since he's already here this time, don't be polite.

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

The reason why there are only so many left is that some of those beggars who fled some of the beggars when he attacked the inside of the saltpeter mine received a lot.

Otherwise, there should be a lot more.

After doing this, there is really nothing too noteworthy for the saltpeter mine for the time being. From his own personal experience and the chat in the world channel, he can draw some valuable information - the lizards and beggars are all there. Constant migration.

After the extremely hot temperature affected the underground ruins, they couldn't bear it, so they drilled out of the ground and migrated to the mountains in groups.

No matter whether it is saltpeter mine or natural sulfur ore mountain, it is estimated that there is no power to meddle.

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

The system will kick all the survivors and beggars out of the secret realm the day before the disaster, but it has not stopped the lizardmen as well.

Are they also affected?

At present, there is no evidence of this, and Lin Yue has no way of knowing whether the fact is because of this.

After all, if not affected by the system, according to his understanding, the secret realm should be the first choice of the lizardmen.

The six robot dogs in the storage space are also set up, and they are specially responsible for the guards and sentries here.

Although the number of robot dogs here is extremely large, all of them have been set to mining mode by him before, and they will fight only when they encounter a crisis.

Lin Yue also placed a medium-sized electric sentry machine gun stand above the gap in the walled fortress. The width here is not hindered at all.

Immediately after that, he also connected the wires to the two small solar power sets, and successfully connected them completely!

Soon, the medium-sized electric sentry machine gun stand flashed light, and Lin Yue also recorded the images of himself, Xiaomeng and Little Ice Lizards, and the robot dogs through his own identification camera.

Of course, the robot dogs here have also been set to the automatic idle charging mode by him, and the special mining program has been reset.

After doing this, the defense of the mine has also been fully completed.

At least that should be no problem until disaster strikes.

"Xiao Meng, can I run back?"

After the other little ice lizards got into the car, Lin Yue found out again that he couldn't get Xiaomeng to sit up too.

This "little guy" also weighs at least a ton from the outside, and maybe heavier. His little car is really not enough for it.

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

But then again, the high temperature is too much... It's not even noon, I feel like people are getting sunburned, and the body temperature alone is estimated to have already exceeded forty.

I touched the seat cushion and found that it was too hot. There must be no problem with bacon and eggs for breakfast.

Hurry to avoid the refuge, the outside is no longer suitable for survival.

Everything in front of him was tanned nearly white like a saltpeter mine, and the only thing that could make him feel normal was the forest that had been burned to coke before.

How long will this ghost weather last?

Forget it, one day today, one day tomorrow... my dear, tomorrow night will really start?

With an air-conditioned room, watermelons and ice cubes to continue his life, Lin Yue didn't feel too uncomfortable.

It's easy for him to say, but it's probably difficult for other survivors to survive.

Feiyue has found something that can generate electricity, and with the help of his air conditioner, he has lived a life that at least won't die of heat, but what about the others?

Giant hailstorms and fire tornadoes really only need one thing to dodge perfectly – get a sturdy basement.

But that was without "extreme heat".

If we can overcome this, we can simply get through what is arguably the saddest 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 the only human being in this different world was him.

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

Supply and manufacture air conditioners in large quantities, provided that all human beings have access to electricity, and this alone will not pass.

Where can I find power generation equipment?

Solar generators, or diesel gasoline generators, these things are hidden in various places in the secret realm that can be found.

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

Even if found, consider diesel and gasoline consumption.

After all, even if he produced countless air conditioners, it would be useless.

There is no basic electricity.

Lin Yue shook his head, indicating that the little ice lizards and Xiaomeng should leave, he took some saltpeter, there was no point in staying here any longer.

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

"Goooo..." Under the fierce sunlight, Xiaomeng was also a little dizzy, and seemed to be thirsty at this time.

"Want to drink water, wait." Lin Yue forgot, he hadn't cooked for them yet. He smelled bad smells in the mine before, 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 down and surrounded the basin. They all seemed to be thirsty.

However, Lin Yue found that they didn't drink it right away, but sprayed extremely cold mist into the basin!

The water cooled down quickly, and soon after the ice flakes, they were able to drink happily.

Good guy, do you use ice water to resist this high temperature and cool your body? It really is…

and many more.

ice!

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

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

Ice can be cooled by putting it in water, and even if it is put there to melt, it can keep the room temperature down!

If a large amount of ice can be produced, wouldn't the survivors be able to escape the disaster of this extremely hot weather?

The little ice lizards, Xiaobai and Xiaomeng can all emit extremely cold spray, if possible, make ice...

No, no.

Even if Xiaobai vomited blood to make ice, they would definitely not be able to supply even one-thousandth of the two billion people.

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

How can modern people make ice without electricity at all? In what way?

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

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

Xiaomeng let out a low growl, stomping on the ground and running towards the shelter quickly, and he also started the car, stepped on the accelerator, and finally glanced at the saltpeter mine.

The robot dogs have mined a lot of ores, and piled up nearly a hundred saltpeter mountains that are nearly 20 meters high.

He can't use so much to make all kinds of explosives, and the role of things like saltpeter seems to be to make explosives, and to make ice...

Make ice?

Make ice!

A thunder flashed through Lin Yue's mind!

Man, you forgot about this!

He felt that his brain was in a state of numbness because he had fought too much with the Lizardmen recently He almost forgot about making ice with saltpeter!

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

The saltpeter ice-making method, which he had seen in the lab class of the chemistry interest group in high school.

He forgot the specific method, but the teacher once said that the method of making ice with saltpeter is the most widely used method discovered by the ancients to realize the freedom of ice even in summer!

After that, the teacher really made a pot of ice with saltpeter!

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

"It seems to be able to verify that if it is really possible, then this time through the disaster is not a problem!"

Lin Yue's heart began to beat fast.

Unexpectedly, I have always held a method that can change the direction of this disaster!
