Homo sapiens.

Unconsciously.

The time has come to Galaxy 4, January 1th.

Although there have been varying degrees of confusion around the world due to the spread of super monkeypox.

However, Homo sapiens is still as stable and safe as ever.

After a full year of construction, the Stratospheric Railway connecting Southeast Asia to Africa and running through the east and west sides of the entire Ceylon Ocean has been officially completed.

The Ceylon Ocean Section of the Stratospheric Railway, with a total length of 4725 kilometers, is one of the three ocean sections of the equatorial stratosphere railway, and is also the shortest part of the three oceans.

Li Qingye just happened to be free recently, so he came to the southern part of Meroe via a synchronous robot, which happened to be located in the equatorial region.

On the north side of Lake Victoria.

You can see an Optimus Pillar, which is the local Lake Victoria Skytrain Station.

After arriving here by air train, there are dozens of carbon nanotube composite cables in the sky above the Lake Victoria Air Rail Station. The position of the cable city is tens of meters, reaching a height of [-] meters in the stratosphere.

And on the stratosphere at [-] meters, there is a large "white cloud".

If you look carefully, you can find this "white cloud" with various lines and mechanical parts on it, that is the stratosphere station of Lake Victoria.

At this time, Li Qingye's synchronous robot was taking the elevator together with several security personnel, and quickly headed towards the high-altitude stratospheric station.

Through the window of the elevator, you can overlook the entire Lake Victoria and the surrounding tropical rainforest.

As Homo sapiens comprehensively promotes the industrialization of agriculture and the indoorization of agriculture, the scale of Homo sapiens' farms around the world is decreasing.

Especially in the tropical rainforest area, many farms in the tropical rainforest have stopped developing, and only temporarily retain the previously developed cultivated land.

After all, Homo sapiens' indoor agriculture now produces 18.6 billion tons of grain a year, plus some of the reserved open-air farms and synthetic food, a total of 32.7 billion tons of grain was produced last year.

And Li Qingye has ordered to continue to increase the proportion of indoor agriculture and synthetic food, and gradually phase out some open-air agriculture that is not of much value.

At this time, the tropical rainforest on the African equator is within the scope of returning farmland to forest.

After all, the soil in the tropical rainforest is poor, and deforestation can only be planted for three or four years. After that, unless organic fertilizers and chemical fertilizers are regularly added, the soil nutrients will be depleted, causing crops to fail to grow normally.

Therefore Homo sapiens has decided to return most of the cultivated fields located in the tropical rainforest.

On the one hand, this is to protect wild animals and plants, and on the other hand, it is also to reduce production costs.

Although the one-time investment cost of indoor agriculture is relatively high, as long as the construction of facilities is completed and various genetically modified crops are added, the land utilization rate will increase dozens of times, and the production efficiency per unit planting area is almost 4 times that of open-air agriculture. ~6 times.

Taking wheat as an example, wheat can only be planted for one season in mid-to-high latitudes, and two seasons at most in areas with warmer mid-latitudes.

However, indoor agriculture can achieve the production intensity of four seasons of the year.

In addition, indoor farming has another advantage, that is, it can reduce genetic pollution. Although the crops of Homo sapiens use genetic recombination technology instead of old-fashioned transgenic technology, there is still the possibility of genetic pollution.

In particular, food crops with a large planting area are usually surrounded by wild species of the same family and genus.

This can easily cause genetic drift.

And this kind of situation is not that the Homo sapiens company is unfounded, but has indeed happened many times.

The reason why Li Qingye is very cautious about genetically modified organisms entering the natural world is because he is worried that the genes of genetically modified organisms will contaminate the genes of wild species.

Indoor farming does not have this hidden danger.

……

Withdrawing Piao Yuan's thoughts, he has already arrived at the Stratospheric Station.

Standing in the waiting room of the station, he looked at the endless stratospheric railway, which looked like a black dragon in the sky.

Due to the near-vacuum environment, the train does not generate strong shock waves and noises during high-speed running.

Two 10 minutes later.

A maglev train stopped in the waiting lane of the station.

"Dear passengers, train No. 34002 from Africa to Southeast Asia is about to set sail. Please get on the train as soon as possible under the guidance of the flight attendants..."

Li Qingye walked onto the train without saying a word.

Many passengers in the same company, seeing Li Qingye in the form of a robot, immediately looked at him very curiously.

Of course, these passengers are all employees of the company, and they naturally know that the company has recently launched a device called a synchronous robot, which can be used for field trips.

At present, this kind of equipment is mostly used in the inspection work of the management.

As soon as they saw the synchronous robot, many people guessed which department's management it was. Although they were very curious, no one rushed to say hello.

After 15 minutes, the train started slowly.

When the magnetic levitation and the magnetic field propulsion system start together, the train starts to move at a uniform acceleration.

This maglev super high-speed train, fully loaded with 1500 passengers, will increase its speed to a top speed of 20 kilometers per hour in 2400 minutes.

Looking at the endless blue sky outside the window, everyone did not feel any discomfort, nor did they notice the terrifying speed of the train at this time.

After all, the outside of the car window is too monotonous, and there is no reference at all.

The 4735-kilometer east-west width of the Ceylon Ocean was crossed by trains in only about two hours.

This speed is amazing.

If you take a plane, it will take at least 3 times more time.

Passenger transportation is not the core business of the Stratospheric Railway. The core business of the Stratospheric Railway is actually freight, and the ladder to and from the near-Earth orbit in the future.

Although it may take several years for the ladder project to start, the relevant design team of Homo sapiens has already been doing various technical verifications.

Li Qingye learned part of the progress through the internal briefing.

The difficulty of the current ladder project lies in how to build the structure near the limit of the Karman line.

If it is Venus, this project is not too difficult. After all, the atmospheric concentration of Venus' atmosphere is hundreds of times that of Earth's, which means that its buoyancy is also hundreds of times that of Earth's atmosphere.

But the buoyancy of the earth's atmosphere is not enough to support such a huge megastructure.

And the design teams of those research institutes also gave related solutions.

For example, the hard arch bridge structure, this scheme is to combine the floating platform of the equatorial stratosphere railway through hard materials, and then form an integrated ring.

In fact, it is similar to a donut, except that the donut should be hard, and the higher the strength, the better.

Li Qingye is very aware of the difficulty.

At the stage of its realization, the Homo sapiens company's demand for extraterrestrial resources was not as high as imagined.

For example, Homo sapiens is not too enthusiastic about mining helium 3 on the moon. The reason is that the resources on the earth can still support the company's development for decades.

Therefore, the ladder project is not a project that is eager for success, but a long-term project.

Maybe, in the future, the cloud palace project of Venus will be completed, and it is also very possible that the ladder project of the earth will not be completed.

While he was wandering, the train slowly stopped at the eastern part of Sumatra Island. The location of this station was not far from Xingdao, and it was specially set up for Xingdao.

He has not been back to Southeast Asia for more than a year, this time Li Qingye intends to use the synchronous robot to carefully inspect the situation of various branches in Southeast Asia.

Thank you for your support (ω｀). Yesterday, I was too tired to sweep the tomb and climb the mountain. I was sore all over the body. The update was adjusted from noon to night.
