Homo sapiens.

The two chatted for a while, and Andre took him to visit the vegetable planting cabin of the scientific research station.

There are a total of 16 vegetable planting cabins at the scientific research station, arranged in four rows and buried in the ice, which can produce various vegetables, as well as watermelons, cantaloupe and strawberries.

Andre cut open a jade cantaloupe: "This kind of planting cabin is really good. As long as there is enough energy, you can grow vegetables and fruits."

Wu Yongxing took a bite: "The sugar content of 18.6 is quite high, but it is a little soft."

"That's characteristic of the breed."

"I still like crisper ones." Although he doesn't like this variety of cantaloupe, Wu Yongxing still ate up that piece: "Is the nuclear power cabin of the scientific research station enough power?"

"It's enough, we only have 150 people, and the equipment doesn't use much electricity."

The Penguin Research Station is equipped with two nuclear power cabins.

This kind of small nuclear power equipment is larger than ordinary containers and has a power generation capacity of 2 megawatts. It is also a thorium-based molten salt power generation system and is specially used for small bases.

Moreover, the waste heat from this kind of nuclear power cabin can supply heat to the scientific research station.

For the extremely cold and uninhabited land of Antarctica, nuclear power is more convenient than other energy sources, and the operating cost is also lower.

If fuel generators or natural gas generators are used, the back and forth transportation will cause the operating cost of the power generation system to soar.

As for the fact that the international agreement does not allow the construction of nuclear facilities in Antarctica, Homo sapiens does not care, because Homo sapiens has not signed it.

After eating melons, the two came to the sample room of the scientific research station.

There are many frozen ice samples on display inside, and more than a dozen researchers are studying the ice samples.

Wu Yongxing didn't bother them, but silently browsed through the experimental reports.

Until he picked up one of them and marked it: [Research Report on Drill Core Sample No. 375 in Enderby]

Open the report, which lists the ice deposits of the earth in various periods obtained by the researchers through the analysis of the drill cores.

Then, through these ice deposits, it is possible to study what happened to the earth in various periods.

"The particularity of the Younger Dryas incident..."

Andre glanced at the report, and explained in a low voice: "This is a geological event 1 years ago. It mainly manifested as a sudden and large-scale global cooling."

"A sudden large-scale drop in temperature?"

"Well, this kind of sudden drop in temperature can cause very serious damage, especially for creatures, even for the current human beings. Except for companies, once other forces encounter this kind of sudden large-scale drop in temperature, they will definitely suffer heavy casualties. "

Wu Yongxing narrowed his eyes slightly: "What is the cause of the Younger Dryas incident? It can't happen for no reason, right?"

Andre replied helplessly: "At present, there is no accurate answer in the academic circles. There are several hypotheses. I personally agree with the North Atlantic warm current change hypothesis."

"Is it the North Atlantic Current that passes through North America and brings warmth to Western Europe?"

Andre said with some concern: "Exactly, in fact, in the past ten years, the intensity of the North Atlantic warm current has been declining, and it has become more and more irregular."

Wu Yongxing fell into deep thought, although Homo sapiens' ability to resist natural disasters was an order of magnitude higher than other forces on Earth.

But it doesn't mean you can be unscrupulous.

Human beings are still fragile and insignificant ants in front of nature.

He thought for a while, and then asked, "If the warm current in the North Atlantic stops flowing, will the whole world enter an ice age?"

Andre shook his head: "Probably not. After all, in the process of human industrialization, a large amount of carbon dioxide has been emitted. Greenhouse gases can reduce the impact of the North Atlantic warm current interruption, but the global temperature will definitely drop by one or two degrees."

After weighing the pros and cons, Wu Yongxing ordered: "Andre, you take the North Atlantic warm current interruption as the subject, write a professional assessment report, and then submit it to the Science Department."

"Okay." Andre nodded.

Chapter 357 Supreme Command ([-])

Egypt.

Due to the blockage of the Nile River, the Southern Canal has only completed the double track on the east side of the Nile River. At this time, it is undergoing a second widening.

After all, the width of the 120-meter river is too narrow. When the container ship of Evergreen Shipping passed through the Suez Canal, the water surface width of the canal was only more than 300 meters, and the depth on both sides was not enough, so a grounding accident occurred.

This is why the Egyptian canal management company of Homo sapiens limits the navigation limit of the canal to 5 tons.

According to the plan, the main line of the southern canal has a single-line design width of 500 meters and a depth of 45 meters. It needs to be excavated at least four times along the canal to ensure a water surface width of 500 meters.

Fortunately, New Luzon Shipbuilding Company and Ceylon Shipbuilding Company will successively deliver 15 giant rhino canal-opening ships within the next year, which will greatly increase the speed of canal excavation.

At this time, the north of Kom Ombo City.

There are not many large ships on the calm surface of the Nile River, mainly because the Nile River is in the dry season at this time, and the industrial and agricultural water on both sides of the river is increasing year by year, resulting in the water depth of the Nile River being less than 5 meters at this time, which greatly affects its shipping. value.

The Gobi Desert New Area is on the south side of the South Canal, on the east side of the Nile River, and is 5.7 kilometers away from the main stream of the Nile River.

The person in charge, Hu Mingliang, and the leader of the planning team, Kamijo Beiyo, are standing on the bank of the Nile, investigating how to make the canal pass through the Nile.

If it is a freshwater canal, there is no need for too much trouble, and it can be directly connected.

The problem is that the southern canal is a seawater canal. Once it is connected to the Nile River, since the altitude of this section of the Nile River is about 58-60 meters, and the southern canal is at the same level as the sea level, the result is that the water of the Nile River will quickly pour into the southern canal. Cut off.

Hu Mingliang turned his head and asked, "Kamijou, is the plan out yet?"

"I discussed it with the planners at the headquarters. If the aerial bridge scheme is adopted, the canal can only pass ships with a capacity of less than 10 tons."

Hu Mingliang took Kamijo Beiyang's tablet computer, which contained the design plan of the overhead bridge.

The specific plan is to build two super-large bridges over the canal, allowing the water of the Nile to pass over the bridges, while the canal passes through the overhead bridge.

This solution is the most time-saving and labor-saving, and at the same time avoids the backflow of the Nile River and the pollution of fresh water by seawater in the canal.

Other ship lock schemes and four-sided lock dam schemes are not as good as the aerial bridge scheme.

It's just that the aerial bridge is good, but its shortcomings are also very obvious.

The altitude of the Nile River here is 58-60 meters, and the altitude of the river bottom is 50-55 meters. If an overhead bridge is built and the thickness of the overhead bridge is added, the height of the bottom of the bridge from the water surface of the canal will be compressed to about 40 meters.

With a passing height of 40 meters, a transport ship of 10 tons can barely pass through.

The design limit of the southern canal is 30 tons.

Hu Mingliang frowned and asked, "Is there any other way?"

Kamijou Beiyang thought for a while: "There is a more troublesome plan."

"Tell me."

Kamijo Beiyo brought up another design plan on the tablet: "Construct two aerial bridges of the seven-level ship lock type, and at the same time dig a drainage tunnel to communicate the upper and lower reaches of the Nile River separated by the aerial bridge."

Hu Mingliang looked at the new plan, which had expanded several times in scale, and was caught in the process of weighing the pros and cons.

In this plan, the aerial bridge passing over the canal in the middle will be raised to a height of 100 meters above the water surface of the canal. The length of this section of the aerial bridge is 1 kilometer.

The bottom of the bridge is 100 meters above sea level, plus the 12-meter-thick bridge structure layer and 12-meter water depth, the dam height of the bridge body is required to be about 30 meters, and the overall altitude is 130 meters.

There is a drop of nearly 70 meters between this height and the water surface height of the Nile River on both sides.

Therefore, three locks are designed on both sides, which can ensure that the 5-ton transport ship can pass through the locks smoothly.

At the same time, two other locks were designed to connect the Nile with the Southern Canal.

Two drainage tunnels that cross the bottom of the southern canal and connect the upper and lower reaches of the Nile are mainly to avoid blocking the water of the Nile.

Obviously, the cost of this solution is several times higher, and the complexity has also risen to a higher level.

But the benefits are also very obvious. The southern canal can be used for barrier-free navigation of 30-ton transport ships, which will have a very important acceleration effect on Homo sapiens' future development of the Sahara Desert.

After Hu Mingliang weighed the pros and cons, he made a decision: "I'll use the second plan. I'll search for it now, and it will be more troublesome to upgrade in the future."

"Alright then! I will use the second plan as the basis and communicate with the headquarters planning and design company."

Hu Mingliang nodded: "I will leave this matter to you."

Suddenly Hu Mingliang's assistant came over and whispered something in his ear. He raised his brows, and then shrugged his shoulders to Beiyang: "There is another matter."

"Haha, it doesn't matter, you go ahead! I also want the geological exploration team to investigate the surrounding geology."

After bidding farewell to Kamijo Beiyang, Hu Mingliang drove his armored vehicle back to the new Gobi Desert area, and then hurried to his office.

At this time, there were two people in the office.

An old Slavic man with a rough face, and a middle-aged man in a space gray uniform.

"Dr. Mikoyan! Major General Du Hai! Hello, I am Hu Mingliang, the person in charge of the Gobi Desert New Area of ​​the Egyptian branch."

Dr. Mikoyan, who previously worked in the aircraft manufacturing department of Aoba Aviation Group, has been transferred to the third design institute of Aoba Aviation Group.

"Hello! Hu, this time we are here to ask you for help." Dr. Mikoyan gave a bear hug directly.

Major General Du Hai took out a blank sheet of paper and handed it to Hu Mingliang.

Hu Mingliang took it, and after tearing off the special film on the surface, he read the special pheromone code on the paper through the pheromone decoder of the biochip.

After 30 seconds, the pheromone on the white paper has completely melted away, turning into an ordinary white paper.

Hu Mingliang, who browsed through the confidential information, replied solemnly: "I understand, I will fully cooperate with your work, and do a good job of keeping it secret and covering it."

"Then I will trouble you." Major General Du Hai immediately saluted.

Open a virtual map of the office.

Du Hai circled an area on the virtual map: "It's right here."

"The east side of the Jiajie Manor in the Kharija Oasis? No problem, but the southern canal needs to wait until the Nile River hub project is completed before it can be advanced to the Kharija Oasis."

Du Hai asked, "How long will it take?"

Hu Mingliang thought for a moment: "The combination of the main ship lock and the drainage tunnel will take about 7 months. It is expected that the canal can be pushed to the Khalij Oasis by the end of this year."

Hearing this time, Du Hai quickly made a decision: "It seems that we must dispatch a batch of transport planes to go to the Khalijah Oasis area in advance."

Then he turned his head: "Doctor, you and the planning team of the space base will be in Kom Ombo for the time being! I will personally take people to the Kharja Oasis area. As for the planning and layout, we will communicate through satellite phones at that time."

"No problem." Dr. Mikoyan didn't have the idea of ​​going to Harija Oasis now, after all, he was almost sixty, and he couldn't help much now.

The three of them communicated for a while, and then they left separately, and began to busy themselves with their tasks.

The layout of the space base in Egypt this time is also one of Li Qingye's orders.

Chapter 358 Sunda Ancient Land

The Java Sea between Borneo and Java Island.

Deep under the sea, a huge underground tunnel runs through the Java Sea, connecting Borneo with the island of Java.

Li Qingye is inspecting the construction of the submarine base here.

Wu Yebo, who is in charge of Java district management, introduced the whole project to him.

"Because the company took back the various subsea oil and gas fields that were sold before, we have now built eight large underground base cities in the Java Sea."

The holographic map in front of me is completely different from the map of Southeast Asia issued by ordinary publishing houses.

Thanks to the development of technology, Homo sapiens' internal definition of territory includes the controlled sea areas.

The Homo sapiens-controlled areas in Southeast Asia, including territorial waters and marine exclusive economic zones, are included in the territorial scope.

The Java Sea region at this time was part of the Java District.

Li Qingye stared at the enclosed Sunda Ancient Land, which is currently the shallow sea territory developed by Homo sapiens.

The so-called Sunda ancient land refers to the phenomenon of sea retreat during the last ice age because a large part of the global water resources was occupied by ice sheets.

The sea level at that time was 80-100 meters lower than it is now.

As a result, the ancient Sunda land was exposed to the sea and integrated with the Indochina Peninsula.

The entire Sunda ancient land includes the Malay Peninsula, Sumatra Island, the Straits of Malacca, Borneo, Java Island, the Java Sea, the surrounding waters of the Natuna Islands, and the surrounding waters of the Gulf of Siam (Lake Siam).

The total area is about 400 million square kilometers.

Now 95% of the Sunda ancient land is in the control area of ​​Homo sapiens, so Homo sapiens company uses its own technological advantages to secretly build cities hidden under the sea.

These cities are all built under rock formations with a thickness of several hundred meters, and with seawater nearly a hundred meters high, their defense is higher than some bases on land.

After all, today's missiles have no way to penetrate a rock layer with a thickness of several hundred meters after penetrating nearly a hundred meters of water.

The water body has a very strong slowing effect on the high-speed flying missile. Under normal circumstances, the ground-penetrating missile cannot penetrate the seabed rock formation, because the kinetic energy has been exhausted by the water body.

Of course, Li Qingye is very clear that once a war really starts, there is a high probability that it will be the rhythm of nuclear bombs.

However, sea water can also suppress the destructive power of nuclear bombs in nuclear strikes, especially those sea areas with a depth of more than 1000 meters, where nuclear explosions are difficult to strike.
