At night, the android drove the hideous modified truck all the way to the port.

It's four hours away from the port, and around dawn you can bring back the building materials that Xiaoyu bought on the Internet.

Early the next morning, Li Mingyu was woken up by the roar of a truck.

The large, modified truck rampaged through the primeval forest like a bulldozer, and rows of thick giant trees fell in unison under the jagged harvest of the front of the truck, and then the mechanical arm trimmed off the branches and placed in the middle of the truck, where they were broken into extremely fine wood chips, mixed with other building materials, and transported to the rear of the truck, and a horizontal row of machines threw the mixture on the ground.

Machines that use plasma as fuel spew high-temperature flames on the freshly poured mixture, and the otherwise soft mixture quickly condenses into a flat asphalt road.

The truck drove all the way from the port to the tent that Li Mingyu had set up last night, and a four-lane road connected to the port was paved.

In the past, it would have taken at least a few years to build a road of this length, and it would have taken countless financial and material resources to complete, but because of the olefin-3 polymer material, this time and cost will be greatly shortened.

The giant trees themselves are a versatile building material, and the machinery of the truck bed can break the giant trees at the molecular level to form a viscous organic crystal solution, which, when fully mixed with a small amount of olefin-3 polymer material, quickly fibrosifies and becomes a liquid that resembles a highly concentrated spider web structure.

By spreading this liquid on the surface, the liquid will quickly react with the soil and stick to the surface, and by evaporating the water in the liquid at high temperatures, this organic crystal solution will become harder and stronger than cement, and this organic crystal solution is very suitable for use as a building material.

With a road to transport supplies to the base, Xiaoyu quickly connected with a large raw material supplier from a neighboring country.

It is certainly not enough to rely on trees alone, and the main project must still use metal raw materials.

30,000 acres of land is not large, and Li Mingyu plans to build a temporary production base first.

First of all, the production line of tools, at present, it is poor and white, it can be said that there are no tools at hand, and it is certainly unrealistic to build a production base from scratch.

The speed of the raw material supplier is very fast, after all, Xiaoyu uses US dollars to settle, and gives half of the deposit in advance, and at about noon, trucks are driving from the newly built road from a distance.

"Huh? How did you build such a wide road here? I didn't even have a delivery last week? Many of the drivers who delivered the goods were residents of the neighborhood and were surprised by the road that appeared out of thin air.

Xiaoyu ordered a variety of things, metal ores, steel cement, rare gases, new building materials are almost everything, and the android directs the delivery truck to sort the goods into categories in the open space.

The converted truck was not idle for a moment, moving in a circle from the center of the flat land, cutting down all the surrounding trees, and soon a large area of land was leveled.

After an overnight self-replication, the industrial-grade 3D printer has printed a fairly objective amount, and some printers continue to replicate themselves, while others begin to assemble in order to print larger production equipment.

After pouring sufficient raw materials, a behemoth more than 30 meters high and 20 meters wide, assembled by more than 30 printers, slowly started, and more than 10 meters long robotic arms began to spray a variety of different materials from all directions according to the established printing plan.

This was the first heavy mechanical equipment that Lee Mingyu was preparing to print: the molecular furnace.

At present, the building materials on the market are too fragile, and if you want to build large-scale buildings, without exception, you must build a structure through steel bars and pour concrete, which is effective, but has the disadvantages of long cycle and high cost.

In the technical solutions provided by Xiaoyu, Li Mingyu was able to choose a more efficient, safe and fast way to build his base.

The speed of the industrial-grade 3D printer is very fast, and although the molecular furnace is huge, it does not need to be too delicate to print, and it only takes four or five hours to complete the printing under the rapid spraying of dozens of robotic arms.

After the metal furnace was built more than ten meters high, the android quickly pulled the wood that had been cut down from the previous leveling land and put all the wood into the molecular furnace.

All of this wood is dissolved into an organic crystalline solution that is used as part of the base's building materials.

The production line of olefin-3 type and olefin-3 polymer materials was quickly printed by the printer in the case of sufficient raw materials, no way, the new materials currently peddled on the market are too inferior, especially in the Gulf of Guinea, where chickens do not lay eggs and birds do not, the new materials peddled are almost all unqualified defective products, Li Mingyu does not dare to use these materials to build his own base.

But it is not without its advantages, the crude oil produced here is of high quality, and the imported ore is also cheap, and a few thousand dollars can buy several large truckloads of iron ore.

Li Mingyu looked at the busy android and called up the urban planning plan he had selected last night.

The pale blue three-dimensional projection was suspended in front of Li Mingyu, and a complex and huge city phantom loomed, the design was of course designed by Xiaoyu, and Li Mingyu only provided some ideas.

The current 30,000 acres is only the southwest corner of the city, and there are still large areas of primeval forest to the east and north of this land, because it is in the center of the Congo Basin, and the terrain is relatively flat.

The whole city adopts the method of splicing and combination, and the layout is according to the different functional modules, which has the advantage of being able to quickly assemble as long as the production line of the corresponding functional modules is produced.

These urban modules are built to the specifications designed by Kodama to ensure the consistency of the individual modules in the splicing process.

The first is the foundation part as well as the underground pipe network part.

The organic crystal solution produced by the molecular furnace is put into the industrial-grade 3D printer, and the 10,000*10,000 foundation is quickly printed.

Each foundation is surrounded by special devices that, once laid in the open ground, continue to drill downwards and extend anchors to a certain depth to prevent the foundation from being displaced by the settlement of the terrain.

In the past, the construction was to avoid terrain settlement by digging deep into the foundation, which is not only simple and efficient, but also more reliable than traditional construction methods because of the increase in material hardness.

The 30,000 acres of land was quickly tiled on rows of 10,000*10,000 foundations, and the production base also had a rough outline.

But it's still far from what the city looks like.

Industrial-grade 3D printers have printed a lot of construction robots, which are only equipped with shallow training artificial intelligence, but some handling work is enough.

Towards night, a group of industrial-grade 3D printers printed thousands of polymer walls were finally completed, more than 1,400 meters long, and the three-meter-thick polymer walls were spread on the ground, looking like a long and wide runway.

The robot fixes a polymer wall on the most central foundation, and then uses a jack-like device to erect the polymer wall at the bottom of the fixation.

A wall with a silver-gray sheen stood in the clearing, which was not very conspicuous from a distance because the sky had darkened.

As the walls were constantly erected by robots, a building with a height of more than 1,400 meters was built.

However, the building has only one shell, and the inside is still empty.

According to Xiaoyu's calculations, this kind of building has a service life of seven or eight hundred years even if it is not maintained, and the safety is better than that of traditional concrete pouring high-rise buildings.

The robot moved various other types of polymer walls into the building little by little, and began to build the internal structure of the building, layering it according to the height of three meters, and the building has 450 floors.

After seven or eight hours of continuous installation, the internal frame of the entire building was basically completed, and only the furniture and decoration were installed inside, and from the outside the building was almost indistinguishable from other concrete buildings.

If you insist on the difference, it can only be said that this newly renovated building looks more high-end and magnificent, after all, the height of more than 1,400 meters is placed there, and from a distance it looks like a sharp sword straight into the sky, if the weather is clear, it can be seen in a radius of hundreds of kilometers Its silver-gray appearance.

Although the exterior of this building is similar to that of a traditional building, the interior design is very different from that of a traditional building.

First of all, the interior of the polymer wall, the internal wall of the entire building is intelligently designed, that is to say, any wall of the building can be used as an intelligent terminal to interact with people, and the entire building is controlled by built-in artificial intelligence, which can intelligently adjust the color, temperature, humidity and light of any room in the building, giving residents the most comfortable living experience.

After the completion of the first building, the second building was then assembled, this building is next to the first building, but the height is only more than 900 meters, in the urban planning map selected by Li Mingyu, the height of the floors decreases from the center to the periphery, and the construction of the entire southwest of the city presents an inverted cone shape with a medium high and low circumference, which can maximize the use of land area on the one hand, but also leave room for future reconstruction.

The industrial-grade 3D printer is constantly printing with high efficiency, and the polymer wall is continuously printed out like screws produced on the assembly line, and the robot quickly assembles the printed polymer wall into a fixed building, and a small town that has begun to take shape has been built almost overnight.

That night, instead of staying in the tin tent he had set up last night, Lee Ming-woo moved to the top floor of the first building.

It has been furnished very well, sofas, tables and chairs are readily available, all printed out by the printer as a whole, although it is still a little difficult to decorate the whole building in one night, but there is no problem with only arranging the top floor.

Li Mingyu lies on a large white and soft bed, the surrounding walls are set to be completely transparent, and the endless primeval forest can be seen at a glance, lying here as if he is in the clouds.

The temperature control system of the entire building is operated by Li Mingyu alone, and there is not the slightest coolness in the top floor of the 450th floor, and the room has maintained a suitable temperature of 22 degrees.

This is the efficiency of the future with the blessing of technology!

In one night, a city that was beginning to take shape rose from the ground.

As the initiator, Li Mingyu watched the busy construction robots the size of ants under his feet assemble the buildings one by one, and sighed with emotion in his heart.

"It would be nice to have a glass of red wine at this time." Li Mingyu shook his head and said with a smile.
