Unconsciously.

The time has come to the 4th year of the galaxy, January 5th.

Although there are varying degrees of chaos around the world due to the spread of super monkeypox.

However, the company is as stable and secure as ever.

After a full year of construction, the stratospheric railway, which connects Southeast Asia to Africa and connects the east and west sides of the Ceylon Ocean, has been officially completed.

The Ceylon Ocean section of the Stratospheric Railway, with a total length of 4,725 km, is one of the three oceans section of the Circum-equatorial Stratospheric Railway, and the shortest part of the three oceans.

Li Qingye happened to be free recently, so he came to the south of Meroë through a synchronous robot, which happened to be located in the equatorial region.

On the north side of Lake Victoria.

You can see a Optimus Pillar, which is the local Lake Victoria Air Rail Station.

After passing through the air rail to here, above the Lake Victoria air rail station, there are dozens of carbon nanotube composite cables, and the position of the cable city is tens of meters, reaching the height of 20,000 meters in the stratosphere.

And on the stratosphere of 20,000 meters, there is a large "white cloud".

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

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

Through the elevator window, you can look down on the whole of Lake Victoria and the surrounding rainforest.

With the comprehensive promotion of agricultural industrialization and indoorsization of agriculture by Homo sapiens, the scale of Homo sapiens farms around the world is decreasing.

In the rainforest region in particular, many farms in the rainforest have stopped exploiting and are only temporarily retaining previously developed farmland.

After all, Homo sapiens' indoor agriculture now has reached 1.86 billion tons of grain a year, and with the reserved part of the open-air farms and synthetic food, a total of 3.27 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 does not have much value.

At this time, the tropical rainforests of the African equator are within the scope of returning farmland to forests.

After all, tropical rainforests are so poor that they can only be planted for three or four years, after which they will be depleted of nutrients and crops will not be able to grow properly unless they are regularly supplemented with organic and chemical fertilizers.

As a result, Homo sapiens has decided to retire most of its cultivated land in the rainforest.

On the one hand, this is to protect wildlife, and on the other hand, to reduce production costs.

Don't look at the one-time investment cost of indoor agriculture is relatively high, but as long as the construction of facilities is completed, coupled with various genetically recombinant crops, its land utilization rate will be increased by dozens of times, and the production efficiency per unit planting area is almost 4~6 times that of open-air agriculture.

In the case of wheat, for example, wheat can often only be grown for one crop in the middle and high latitudes, and only two crops in the warmer latitudes.

Indoor farming, on the other hand, can achieve year-round production intensity.

Another advantage of indoor farming is that it can reduce genetic contamination, although Homo sapiens' crops are genetically recombinant instead of old-fashioned transgenic technology, but there is still the possibility of genetic contamination.

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

This can easily lead to genetic drift.

And this situation is not that Homo sapiens is unfounded, but that it has indeed happened many times.

The reason why Li Qingye is very cautious about the introduction of genetically recombinant organisms into nature is that he is worried that the genes of genetically recombinant organisms will contaminate the genes of wild varieties.

Indoor farming does not have this hidden danger.

……

Retracting his distant thoughts, he had reached the stratosphere station.

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

Due to the near-vacuum environment, the train does not produce strong shock waves and noise during high-speed driving.

Twenty minutes later.

A maglev train stopped in the station's waiting lane.

"Dear passengers, train 34002 from Africa to Southeast Asia is about to depart, please board the train as soon as possible under the guidance of the crew......"

Li Qingye walked onto the train without saying a word.

Many passengers in the same company saw Li Qingye in the form of a robot, and immediately looked at it 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 equipment is mostly used in the inspection work of the management.

As soon as they saw the synchronization robot, many people guessed which department it was the management of, and although they were very curious, no one rushed over to say hello.

Fifteen minutes later, the train started slowly.

When the magnetic levitation and magnetic field propulsion systems are started together, the train begins to accelerate evenly.

The maglev ultra-high-speed train, which carries 1,500 passengers, boosts its speed to a top speed of 2,400 kilometers per hour in 20 minutes.

Looking at the endless blue sky outside the window, everyone did not feel any discomfort, nor did they perceive 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 4,735-kilometre width of the Ceylon Ocean was crossed by a train in only about two hours.

This speed is amazing.

If you take a plane, it will take at least 3 times as long.

Passenger transportation is not the core business of stratospheric railways, which are actually freight transportation and the ladder to get up and down the low-earth orbit in the future.

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

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

The difficulty of the current ladder project is how to construct the structure near the boundary of the Kármán line.

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

But the Earth's atmosphere is buoyant enough to support such a massive structure.

The design teams of those research institutes also gave relevant solutions.

For example, the rigid arch bridge structure is a floating platform of the circum-equatorial stratospheric railway that combines hard materials to form a single ring.

In fact, it is similar to a doughnut, except that the doughnut should be made hard, and the stronger the better.

Li Qingye knew very well how difficult it was.

In fact, at this stage, the demand for extraterrestrial resources of Homo sapiens is not as high as expected.

For example, Homo sapiens is not too keen on mining helium-3 on the moon, because the earth's resources can support the company's development for decades.

Therefore, the Ladder project is not a rush project, but a long-term project.

Perhaps, in the future, Venus's cloud palace project has been completed, and it is very possible that the earth's ladder project has not been completed.

While he was wandering the world, the train slowly stopped in the eastern part of Sumatra, a station not far from Star Island, which was also specially set up for Star Island.

He hasn't been back to Southeast Asia for more than a year, and this time Li Qingye plans to use synchronous robots to carefully inspect the situation of various branches in Southeast Asia.
