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

When it comes to road construction, although Lin Yue doesn't dare to guarantee that he is the first, he must be the one with the longest mileage.

Although the asphalt road is smoother and more aesthetically pleasing, the disadvantages are indeed fatal.

In this extremely hot weather, the fierce sunlight also brings it close to the melting limit, and if you continue to drive on it, it is likely to damage the smooth road surface, which can lead to various problems.

Therefore, Lin Yue chose not to pave the asphalt road anymore.

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

Moreover, there is actually a bug that can be used in the paving thing, that is, it is constantly broken down into design drawings, just like last time, he directly made up to ten kilometers of asphalt road design drawings, if the materials are enough, he can further change these ten kilometers into twenty kilometers, forty kilometers, and one hundred kilometers!

This can naturally become the most important help for him to engage in 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 didn't care what the other survivors thought of the road, and he didn't care what the lizards and beggars thought of it, but if anyone tried to destroy it or put obstacles in his way.

Then the end is very simple.

Lizardmen leave treasure chests, survivors beggars leave storage space.

Lin Yue felt that there was no need to reason with unreasonable people, and directly let him live alone on the scene, and the matter would be perfectly resolved.

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

When leaving the Berg Ore Mountain, he did not forget to lay a small solar power set and sockets, and also edited the program for the robot dogs to charge them in their spare time.

This way, they can really work 24 hours a day, and they can collect ore more efficiently!

Before the disaster officially arrives, the robot dogs will not be able to rest properly.

Having said that, 30 stones to pave a five-meter-long and wide road is actually quite expensive, but the number of stones he has is unimaginable, and the total number of stones dug up by the robot dogs working around the clock is enough for him to pave this road, and even further.

Xiao Meng smelled the owner's scent early on, and he excitedly pushed the huge rock away from the gap in the walled fortress, and excitedly circled the owner's car with the black dot and green paws and other small Xiaoice lizards.

"It's been a hard two days!" Lin Yue took out the meat steak of the lion-headed bear to reward these friends who had stuck to their hard posts for two days.

"Whoa!" Xiao Meng was especially excited, the weather was really bad, terrible.

With the help of a robot dog, he and the other Xiaoice lizards had to dig a small cave to escape the torture of the heat.

For the past two days, they have been quiet except for the first morning, when they were attacked by a few hundred lizardmen.

The hundreds of lizardmen didn't have time to get them to do anything, and the robot dogs were all done.

Xiao Meng felt depressed about this, but after seeing the capable robot dogs continue to mine the ore of the huge saltpeter mine, stacking them on top of each other in the mountains of ore, they are also quite admired.

However, the boring life and the hot weather made them miss the life in the shelter even more, and since the last time Xiaobai came to deliver food, they have insisted on waiting for the arrival of their master so that they can be brought back.

Lin Yue's side did think so too.

Take the Xiaoice lizards and Xiao Meng back to the shelter together, and 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 blueprint of the stone watchtower!] 】

Okay, this can be set up in the Vault now, but he doesn't need a watchtower, it's more suitable as a base for a medium-sized electric sentry machine gun mount.

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

Then, Lin Yue started collecting non-stop.

[You have obtained the Vault Blueprint X1]

[You have obtained the Vault Blueprint X1]

【You have gained ......】

The sound of the system continued to sound.

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

Lizardmen and beggars had previously gathered here, leaving quite a few shelters behind, and these shelters became one of his trophies after the saltpeter mine battle.

It's just that he left in too much hurry last time, and he didn't completely pocket them, and since he has already come this time, then you don't have to be polite.

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

The reason why there were so many left, he thought it was also because some of the beggars had fled from the inside of the saltpeter mine before.

Otherwise, there should be quite a few.

After doing this, there really isn't anything too noteworthy on the saltpeter mine side for the time being, and from what he has seen before, as well as from the World Channel chat, he can draw some valuable information - the lizards and beggars are constantly migrating.

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

Whether it is a saltpeter mine or a natural sulfur ore mountain, it is estimated that there is no strength to touch it.

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

The system will kick all survivors and beggars out of the realm the day before the disaster, but it will kick the lizardmen out without stopping.

Are they also affected?

There is no evidence of this yet, and Lin Yue cannot know whether the truth is because of this.

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

Set up the six robot dogs in the storage space as well, and be responsible for the guards and sentry here.

Although there are a large number of robot dogs here, they have all been set up by him as a mining mode before, and they will only start fighting when they encounter a crisis.

Lin Yue placed a medium-sized electric sentry machine gun platform above the gap in the walled fortress, and the width of this place was not hindered at all.

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

Soon, the medium-sized electric sentry machine gun table flashed light, and Lin Yue also recorded the images of himself, Xiao Meng and Xiaoice lizards, and the robot dogs through his own identification camera.

Of course, the robot dogs here have all been set up by him to automatically charge in idle time, and the program for mining has been reset.

With that in mind, the mine is fully defended.

At least until disaster strikes, there should be no problems.

"Xiao Meng, is it okay to run back?"

After the other Xiaoice lizards got into the car, Lin Yue found again that he had no way to let Xiao Meng sit on it.

This "little guy" also looks at least a ton in size, and maybe it will be heavier, and his little car is really not enough to let it come.

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

But then again, the heat is a bit too much...... It's not yet noon, and I feel like people are going to be sunburned, and the temperature alone is estimated to be more than forty.

I touched the seat cushion of the saddle and found that it was already hot, and there was definitely no problem with getting a bacon egg on it for breakfast.

Hurry up and take refuge, it's no longer suitable for survival outside.

Everything in front of him seemed to be as tanned to almost white like a saltpeter mine, and the only thing that made him feel normal was the forest that had been burned to char before.

How long will this weather last?

Forget it, one day today, one day tomorrow...... Good guys, it's going to start for real tomorrow night?

With an air-conditioned room, watermelons and ice cubes to continue his life, Lin Yue didn't feel much uncomfortable, and he was just uncomfortable for a while when he went out to collect supplies.

He's good to say, but the other survivors probably won't be able to get through it.

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

Giant hailstones and firespouts only need one thing to dodge perfectly – get a sturdy basement.

But that was in the absence of "extreme heat".

If we can overcome this, we will be able to easily survive this disaster, which is arguably the saddest disaster since the beginning of the year.

To tell the truth, Lin Yue also wanted to use his ability to help all the survivors in this world, and he really didn't want to see that the only human being in this other world was him.

But, this time, so far, there really isn't a clue.

Mass supply and manufacture of air conditioners, provided that all mankind has access to electricity, and this level alone cannot be passed.

Where is it so easy to find power generation equipment?

Solar generators, or diesel-gasoline generators, these things are hidden in various places where the secret realm can appear.

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

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

In this way, even if he produced countless air conditioners, it was useless.

I don't have even the most basic electricity.

Lin Yue shook his head and signaled that the Xiaoice lizards and Xiao Meng should go, and he took some saltpeter, and there was no point in continuing to stay here.

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

......Under the fierce sun, Xiao Meng was also a little wilted, and he seemed to be a little thirsty at this time.

"I want to drink water, wait." Lin Yue forgot that he hadn't cooked for them yet, and he had smelled a bad smell in the mine before, probably because the food had deteriorated.

He took out a large basin and poured water from the 4L mineral water bottle inside, and the Xiaoice lizards jumped directly and surrounded the basin, seemingly thirsty.

However, Lin Yue found that they didn't drink it right away, but spewed out a stream of extremely cold mist at the basin!

The water cooled down quickly, and soon after the ice had been raised, they drank it with pleasure.

Good guys, can you use ice water to resist this hot weather and cool your body? Really......

Wait a minute.

Ice!

Lin Yue slapped his head violently! Yes, there's ice!

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

Ice in water cools down, and even if it melts there, the room temperature will continue to drop!

If you can make a lot of ice, won't it be possible for the survivors to escape the catastrophe of this extremely hot weather?

Xiaoice lizards, whites, and warriors can all spray Extreme Cold Spray, and if they can, make ice ......

No, no.

Even if they vomit blood to make ice, they will definitely not be able to supply even one thousandth of the more than 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.

In the case of a complete absence of electricity, modern people make ice? In what way?

Lin Yue felt that he could give up this idea, if those people really couldn't bear it, there was no way, he didn't have magic or anything, and he couldn't change so much ice.

"Let's go, let's go back quickly, Xiaobai, they should also be in a hurry."

Xiao Meng let out a low roar, thumping on the ground and running quickly in the direction of the shelter, while he also started the car, put his foot on the accelerator, and took one last look at the saltpeter mine.

The robot dogs mined a lot of ore, piled up nearly 100 saltpeter mountains nearly 20 meters high, if they were all taken back, it was estimated that they would have to come and go back several times.

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

Ice making?

Ice Making!!

Lin Yue's mind seemed to flash a thunderbolt!

Good fellow, you forgot about it!

He felt that his brain was almost in a state of numbness because of the recent battles with the lizardmen, and he had almost forgotten about saltpeter ice making!

Isn't saltpeter ice the best solution to the problem of extreme heat disasters?

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

He forgot the specific method, but the teacher said at the time that the saltpeter ice method was the most widely used method discovered by the ancients to achieve the freedom of ice cubes even in summer!

Then, the teacher did make a pot of ice with saltpeter!

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

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

Lin Yue's heart began to beat rapidly.

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