Li Qingye controls the synchronization robot and goes to other exhibition areas of the venue.

Due to the huge investment of manpower and material resources, each subsidiary of Homo sapiens has its own expertise.

For example, the Coral Construction Group in front of them, in addition to the engineering termites that have been put into use before, they have also developed engineering polyps.

After several technological upgrades, engineering termites and engineering polyps have become extremely powerful.

Engineered polyps are used exclusively for the construction of subsea projects, while engineered termites are used in surface engineering, especially in large-scale projects, where these two engineering organisms are more effective than engineering machines.

Li Qingye was in the exhibition area of coral construction, and saw a building built on the sand, which was built using engineering termites.

The narrator also tried his best to explain the relevant situation to him: "...... This is a simulated desert environment, where engineering termites can quickly build their houses, roads, and dikes with a certain supply of nutrients and food. ”

Then the narrator called up the holographic projection.

In the picture, there is the yellow sand of the Sahara Desert.

However, in the midst of this yellow sand, there are large buildings.

Li Qingye has been in Africa for more than a year, so he naturally knows what this is.

This is the interior of the central Sahara Desert, and even if Homo sapiens built countless seawater canals and a large number of seawater farmland in the low-lying areas of the Sahara Desert, it still did not turn the interior of the central Sahara into a savannah climate.

Originally, the Sahara Desert didn't have anything, but the wind gradually pushed the sand from the higher places to the lower places, and it also caused sandstorms.

This poses a serious threat to the renovated areas of the Suyinshi and Numidian branches.

Homo sapiens has been trying to tame the Earth's climate, and naturally it will not compromise with sandstorms and desertification, but has launched an extremely aggressive offensive.

The Coral Construction Group is one of the main forces of Homo sapiens attacking the desert.

They hunt large sand dunes that move.

And how to hunt sand dunes involves engineering termites in front of you.

Normally, to completely wipe out a desert, Homo sapiens will adopt a complete set of plans, including: building a stilt city, using the stilt city as a point, diverging lines in all directions, connecting lines to form a network, and then solidifying one grid after another.

In it, Tall Leg City is the command center of engineering termites, as well as a supply station for nutrient solution and food, using disposable plastic pipes as lines, allowing engineering termites to expand in all directions along these pipes, and the pipes can deliver nutrient solution.

Engineered termites feed on nutrient solutions and protein particles, and then use desert sand and soil as raw materials to construct a variety of buildings.

Since it is to destroy the desert, there is no need to use steel bars, and there is no need to require the strength of the structure to be too high, as long as the engineering termites can complete the task with the fastest speed and the lowest cost.

There are about 5000~70 million termites in this standard engineering termite colony in front of you, and in the case of sufficient nutrition, you can build a building with a length of 10 meters, a height of 2 meters, and a width of 0.5 meters a day, and the strength of the building is similar to that of ordinary cement pouring.

It doesn't seem like a good speed, but in reality, it's just a standard termite colony, and Coral Construction Group often invests tens of thousands of standard termite colonies at once.

In other words, the termite colonies that are placed around the city can build buildings hundreds of thousands of meters in length in a day.

After dividing the desert into a grid, Coral Construction Group will invest in a second type of engineering termite, which can spit out special formic acid to quickly solidify the surface of the desert, and the thickness of the solidified layer can usually reach 2~3 cm.

In this way, Homo sapiens has wiped out millions of square kilometers of mobile deserts, firmly anchoring them.

The fixed desert has formed an endless wonder in North Africa, and even in outer space, you can see the solidified area like terraces.

This solidified desert is not left unused there, but used to arrange solar panels.

At present, the Sahara Energy Group, a subsidiary of Homo sapiens, has laid 370,000 square kilometers of solar panels in the solidification zone of the Sahara, generating an astronomical amount of electricity every day.

Due to the large number of solar panels laid in the curing area, the curing layer under the solar panels does not receive much solar energy, which in turn causes the temperature on the ground to be not high during the day and become colder at night.

On the other hand, because Homo sapiens has built seawater canals and seawater farmland in low-lying areas on all sides of the Sahara Desert, the air humidity in the Sahara has increased a little.

The ultra-low temperature at night causes water molecules in the air to condense on the back of the solar panels, which in turn gradually increases the humidity of the local surface.

Now, Homo sapiens has put some organic fertilizer and sand into these grids, and then sown seeds of various low, drought-tolerant herbs.

Quite a few places have been turned into lush grasslands.

Homo sapiens, which has always believed that it can control the earth's climate, is in a position to excel in this regard.

On the African side, Li Qingye has also participated in several related climate symposiums to discuss how to control the climate of the Sahara Desert.

The mobile desert areas that solidify the Sahara Desert are a part of the regulation of the earth's climate.

Of course, Li Qingye also knows about some secret projects that are not known, such as the ocean current control project.

Researchers at Homo sapiens have done various simulations and analyses on how to control ocean currents, and have come up with a number of solutions.

For example, the construction of dense guide towers on the seabed, these guide towers are required to be able to regulate the temperature, salinity, pH, seaweed concentration and oxygen concentration of the seawater.

The project currently has several test sites, such as several core straits in Southeast Asia, as well as several currents in the Ceylon Ocean, which are among the targets of the test.

Originally, Homo sapiens would not have carried out the actual measurement of climate control research so quickly.

However, with the North Atlantic Current's disruption and systemic disruption of global ocean currents, Homo sapiens has given Homo sapiens an opportunity.

Anyway, now that the global ocean currents have been chaotic, Homo sapiens does ocean current control and guidance experiments, so naturally it doesn't have to be too constrained.

By regulating the parameters of the water entering and exiting the Strait of Malacca and Lombok, many researchers have found that the climate can be controlled.

But this requires a big premise, that is, to completely control the entire earth, whether it is sea, land, or glaciers, it requires sufficient control equipment.

In addition, a global climate simulation system should be established, and preferably in low-Earth orbit, a device that blocks solar energy, such as a low-Earth orbit solar power system.

In this way, it is possible to regulate the intensity of solar radiation, ocean currents, ground temperature, air humidity, and so on.

Although the climate control mechanism is just in its infancy, Li Qingye is still very confident in Homo sapiens.

After all, this is also the core of the promotion of a first-level civilization, if you can't even control the climate and geological activities of the home planet, then you can't be called a first-level civilization.

Li Qingye came back to his senses and walked around the venue again before leaving Sing Tao with a few security guards and heading to Thonburi for the next stop.
