There are many types of disasters.

There are two types of disasters: man-made disasters and natural disasters.

It can be said that meteorological, biological, and environmental disasters that cause loss of life and property to human beings have played an extremely important role in the entire history of mankind.

Disasters accompany the entire course of human development, and they also witness the history of human beings becoming stronger.

Snow storms, earthquakes, acid rain, floods, hurricanes, thunderstorms, extreme heat, fire tornadoes, giant hailstorms.

These disasters, which have been experienced countless times in the history of human development, are also constantly being staged in this other world.

To date, however, humanity has not experienced a single catastrophe at all.

In other words, this catastrophe disappeared long before the birth of mankind.

"The time when the concentration of oxygen was much higher than the proportion of oxygen in the air on the modern Earth......"

Lin Yue muttered to himself, he was quite familiar with this time.

During the time he used to work at the Meteorological Observatory, he was able to go through various meteorology-related books on the large bookshelf in the office in his spare time.

And this rich oxidation era was introduced in a book about ancient climate and meteorology.

The Earth's rich oxidation era occurred between the Devonian and Permian periods, and the concentration of oxygen even reached 30%, much higher than the current 21%.

At that time, plants flourished and countless creatures were born.

The reason why I can remember it so clearly is also because there are a lot of illustrations about the huge insects in that period of time in the book, which makes Lin Yue, who is quite interested in these things, quite fascinated.

Later, however, when he went to the library to read books on the Devonian Permian period, he found that the giant insects were not caused by the increase in oxygen concentration.

The abundance of plants plunged the earth into green, and there was also a lot of algae growing in the water.

Plants release large amounts of oxygen, which extracts carbon dioxide, a greenhouse gas from the atmosphere, causing the earth to cool down, not only completely relieving the greenhouse effect caused by the eruption of supervolcanoes, but also plunging the earth into an ice age.

The excessively high temperature difference made a huge number of organisms unable to adapt and died in large quantities, thus giving birth to the mass extinction event of the late Devonian period!

He hadn't thought about the disaster that plants would create, and if he hadn't happened to see the big bug pop out, he would have really forgotten about it.

"It is estimated that there are no giant bugs, but the final result of the rich oxidation era - a big cooling, is estimated not to be too far away!"

Although this is an extremely long time on Earth, in this other world where anything can happen, such a thing may just come and go suddenly.

It's like the last extreme heat disaster, who would have thought that the weather that was still twenty or thirty degrees every day before would be considered comfortable and comfortable, and finally soared directly to sixty degrees?

"Devouring the Starry Sky: Signing in to Become a God"

This is something that would never happen on Earth, but it is extremely easy to happen in this other world.

Lin Yue felt that this disaster might not be too simple.

Plants grow wildly, bringing more than just cooling. The taller and denser plants also make the little bugs that don't know where to hide, and they can make the various mutated creatures that can provide food extremely difficult to deal with!

The survivors have managed to change their stance with sharp weapons and those fierce mutated creatures, but after the plants grow wildly, I am afraid that they will return to the way they were!

At the same time, mutated creatures that are the main food become more difficult to capture, and famine may also come unexpectedly!

Not only that, but the overly tall weeds will also be the most suitable hiding place for lizardmen and beggars, allowing them to ambush and attack survivors inside.

Lin Yue, the more he thinks about it now, the more he feels that the development after this is too terrifying.

In one day, the weeds are knee-length, and after that?

If it really develops like he thinks, then indeed, the next triple catastrophe will probably also plunge the entire world of survivors into a terrifying situation!

"It's deadly......"

Lin Yue shook his head.

Triple calamity, if this is a calamity, there are two calamities waiting for the survivors to overcome.

This is no easy task.

This time, if we don't think about it, maybe half of the remaining two billion people can be left behind.

"Quack." Xiao Bai didn't understand what his master was thinking at the moment, and his understanding of these was completely blank, but he did feel that the air in this wasteland smelled much better than before.

The small insects in the grass can't get into its eyes at all, and a slight sweep of the tail can sweep a large piece of it.

"Well, Xiaobai, let's go, we can't continue to waste time."

No matter what happens, what happens after that, he still has quite important things to do in front of him.

The river of oil cannot be mined by others, let alone the likes of lizardmen!

Although I don't know how much there is in reserves, every chemical product it produces will be the most important help for him to enter a higher stage in the future!

As an energy source entering a new era, the importance of oil extraction is undeniable.

Moreover, Lin Yue always felt that his final goal after that also had a great relationship with this energy.

Xiaobai spread its huge wings, and soon flew high in the air, and it flew straight to the south.

Lin Yue looked down on the dragon's back, and the weeds covering the entire wasteland like a huge blanket had already occupied the entire field of vision, boundless.

From time to time, some black dots pass through the grass in groups.

Tomorrow, what will this grassland look like?

"When the time comes, I'll have to think of a countermeasure, otherwise even I'll be in trouble."

He hoped that the hypothetical catastrophe he imagined would not actually happen.

Otherwise, the catastrophe will have a serious ripple effect, creating quite complex problems and making it more difficult for survivors to survive.

And, this is just one of the catastrophes, if more? What about an even more horrific disaster?

This kind of thing is extremely scary to think about.

However, he can talk to Fei Yue about this issue when he goes back, he is already one of the few people who can be trusted.

Speaking of Fei Yue's words...... This thing doesn't seem to have been in contact with him since yesterday.,Did you encounter anything?

Or is it too much to focus on exploring secret realms or something?

While Lin Yue was thinking about this, Xiao Bai was also constantly flapping his wings, and in the distance, the oil river and the big pit of the underground fortress could already be seen.

As Xiaobai continued to circle and fall, Lin Yue also stopped thinking.

Xiaobai finally landed in a relatively flat place near the oil river.

"It's good, Xiaobai, you stand there and eat something first, and I'll make this super huge machine first."

Lin Yue looked at the "Oil Extraction and Refining Platform" in the manufacturing column in the system panel and confirmed the various materials needed.

"So, let's start building!"

[You have built: Oil extraction and refining platform!] 】

The familiar white light was not dazzling, and there was also a power that made Lin Yue even more excited!

As the light disappeared, a medium-sized machine as huge as a house appeared in front of Lin Yue!

"This is more than ten meters long and wide, and the height is also more than ten meters high, which is really spectacular." Lin Yue looked at this huge machine and couldn't help but admire!

The huge and technologically high-tech boom, which looks like a giant hammer, is even more powerful!

Although it is completely different from the original oil extraction equipment on the earth, there are many similarities.

But it's clear that it's more sophisticated and more powerful!

The whole body is almost all metallic-based colors, and it shines with a dazzling light in the sunlight.

Numerous intricate and regular pipes are closely arranged, and in the other direction, there is a rather large storage tank.

"It can be built directly at the outlet of the oil river, but it seems that a separate power installation will need to be built to function properly."

Not far from this huge installation machine, Lin Yue arranged the medium-sized photovoltaic power generation array. At the same time, the system beeps again.

[The oil extraction and refining platform and the medium-sized photovoltaic power generation array have been detected, and whether they are docked?] 】

Of course, this is a must.

Lin Yue also complained in his heart, fortunately, he could still use the system to make such an effective connection, otherwise he would have to find a way to connect these two things.

With such a delicate and huge equipment, he is afraid that it will take a lot of energy and time, and he may even fail.

The system is really convenient.

After Lin Yue confirmed, several extremely thick cables successfully connected the two.

[Successfully connected with the oil extraction and refining platform and the medium-sized photovoltaic power generation array, the medium-sized photovoltaic power generation array is being charged, with 1% of the current electricity and continuous charging]

Well? Was the system so smart before? Do you still have a charge reminder?

However, since it can't be started in a short period of time, it is a good time to do something else during this time.

Like, building walls and doomsday bunkers or something?

"Xiaobai, take me to the sky and circle a few times, and I'll see how wide the city wall should be."

Flying into the sky again, Lin Yue carefully observed the surroundings, and after roughly calculating the storage of stones in the storage space, he made a decision.

Xiaobai fell back to the vicinity of the oil extraction and refining platform, and Lin Yue immediately took out the box ruler and began to measure it.

Soon, he stopped fifty meters to the south of the platform, and made a point here, drawing a scoop on the gourd, and the four points were quickly completed.

Then, following the method of the previous time he made the wall, he quickly connected the four points at equal distances on the extension of the points, and the next step was to build the wall.

You have built a thickened wall! 】

Once the first wall is built, the rest of the time is boring, just keep moving around and tapping to make the wall.

Soon, the thickened walls with a length of 100 meters on each side around this oil extraction and refining platform were successfully made!

Once the walls are built, it's time to build a medium-sized electric sentry machine gun station.

The medium electric sentry machine gun has a firing range of 5 to 200 meters, and the horizontal design range is 180 degrees, in fact, only one needs to be set up in each corner of the city wall.

Lin Yue had enough alloy on hand, and after thinking about it, he did place the four machine gun platforms at the four corners of the city wall first.

Next, he built four more and put them in storage.

Coming to the top of the city wall near the center between the two machine gun mounts, he built a sloped platform with a reverse inclination of about 30 degrees out of stones, and placed the machine gun mount on top of it.

Looking at the machine gun platform again, at this moment the two machine guns were already aimed diagonally at the sky!

This is a precautionary possibility that Lin Yue suddenly thought of just now.

In this otherworld, mutated creatures don't just attack from the ground.

The previous species called the Eagle Wing Insect and the strange bird called the Three-Eyed Owl that I came across by chance when I came out at night were all mutated creatures that could fly.

And in the secret realm, there are also those storm lizards.

In case the Lizardmen later knew how to put all those Storm Lizards into the other world, then these medium-sized electric sentry machine guns would also serve some purpose at this time.

After connecting them all to the power supply, Lin Yue also entered the information of himself, Xiaobai and Xiaomeng, and the Xiaoice lizard, and they also immediately turned on the starting light, ready to attack unidentified enemies at any time.

"However, it seems that this defense force is still not enough." Lin Yue looked at the remaining stones, and there were still a lot of things that could be done.

[Successfully docking the oil extraction and refining platform and the medium-sized photovoltaic power generation array, the medium-sized photovoltaic power generation array is being charged, the current power is 23%, and the oil extraction and refining platform can be started in continuous charging, is it open?] 】

At this moment, the system suddenly sounded a beep.

Oh? Can it be turned on? Start now!

A roar rang out in an instant, and the earth began to tremble!

At the same time, the pendulum, which opened like a huge hammer, was also driven by electricity, and quickly functioned!

At this moment, Lin Yue unexpectedly found that the oil river that was originally flowing outside seemed to have a tendency to slowly retract, and after a while, it quickly retracted back to about a quarter!

[The oil extraction and refining platform has been successfully opened! 】

[The oil production platform can produce 200 units of gasoline, 100 units of kerosene, 150 units of diesel, 200 units of asphalt, 50 units of fuel oil, 30 units of lubricating oil, 50 units of paraffin, and 50 units of solvent gasoline per day]

Oh huh? Sounds like a lot of efficiency!

But how much is this unit?

[Output 1 unit is 10 liters/kg]

That seems pretty good, but the question is, isn't it time to start making some storage equipment?

[All outputs will be stored in iron drums, please put the corresponding amount of iron into the raw material input port, if the iron storage is insufficient, the oil extraction and refining platform will not continue to operate. 】

Good guy, why is the system so excited, I feel that there are not so many explanations and explanations before I get something else?

This time it's a bit of an anomaly.

But......

"If you come here, you will get it, no matter what you say, this time you can already get extremely important materials such as oil! Well, it seems that you can be self-sufficient to a certain extent after that! ”

Lin Yue's mood at the moment also began to rise.

The importance of oil is self-evident, and now that he has obtained this precious energy, he will also enter a higher stage in all aspects!

Thus, continue to be the existence of the apex that has always been above everyone in the entire other world!

"Self-sufficient, completely independent of other people, and able to continue to trade other resources that are not needed with others in exchange for what is more needed...... It seems that in some ways, I don't need to do everything at all. ”

Lin Yue felt that he had now stepped into a new stage at this moment, and in this stage, he would also be able to spend more time on what he wanted to do more!
