The elevator swished down quickly, the entire passage was paved with silver-white metal materials, and every time a distance passed, there would be a small light passing by, coupled with the reflection of silver-white materials, so that this downward passage was not so dark, but had some bright feeling.

With the descent of the lifting platform, and the lifting platform is open, the cold wind continues to blow up from below, blowing Dong Chen's clothes and hair hunting and flying, and the lights that flash every time they pass are also fleeting on his face, reflecting his handsome face, which is very different.

Of course, the above pictures of Dong Chen exist in his memory, or some scenes from anime or movies. The real situation is that there is no well-built elevator passage here, and there is no silver-white metal material in the elevator passage, and there is no lighting, and the whole passage is pitch black, and nothing can be seen.

Originally, the fully intelligent construction site, what kind of lighting is needed, and it is not human construction, the laser ranging and scanning device of intelligent machinery solves all the problems.

And the most important thing is that Dong Chen has no hair, and the wind blowing from below does blow the corners of his clothes, but when the wind passes through his head, it can't blow any waves, it is so steady as a mountain, and it is not at all different from those bewitching sluts who have their hair flying when they take an elevator.

This is a temporary elevator, which is used to transport equipment down in the first few days, at the beginning there was only one equipment in the excavation of the downward passage, so the early stage was relatively slow, until the official start of digging the underground space, this elevator was built to transport the equipment down, and then assembled below to use, because this lifting platform is not big, it is not small, that is, a two-meter five-square platform, because it is indoors, so it can not be too big.

After all the equipment is transported, its role is not too big, it will only be used when the robot regularly transports replacement batteries, and Dong Chen's task this time is to build a temporary production workshop here, because the early space below has been dug almost up, and more materials and equipment will be used to expand down or to the side.

Because if he expanded, these existing machines would obviously not be enough, so he had to bring out more materials and production equipment, and he needed more robots.

Just as Dong Chen was thinking about things, a bright light appeared under the downward elevator, and then the bright light immediately jumped out, making Dong Chen, who was used to the darkness, squint his eyes slightly, he had already entered the main space of the base.

This is a huge underground space, there are several headlights in the corners around it, and the intelligent excavation machinery around it is still working, and their bodies are also lit up, illuminating most of the places in this huge space very brightly, only some corners and corners can't be illuminated, which is obviously for Dong Chen, because only he needs to be bright here to see things.

The intelligent excavation machines continue to dig up the soil, and then after crushing, the powdered soil is transported to the large jar in the middle of the body, and then after a series of compression and high temperature and high pressure environments, and then add some reagents from the Academy of Radiation World, it is prepared into the special materials he needs to bond and strengthen the building.

Then the intelligent excavation machinery will inject the prepared reinforcement solution into the surrounding walls every time it advances, and the top of the underground base has been reinforced, so it has not been supported by support columns until now, making the whole space appear extremely empty, which is the role of the reinforcement solution, you must know that this is not a rock layer. As for the foot, forget it, and continue to dig down according to the plan.

The lifting platform stopped steadily on the ground, Dong Chen finally came to the underground, this section of the distance is two hundred and eighty meters, and the height of this space alone is more than fifteen meters, and the length is more than one hundred meters, and it is still expanding according to the design drawing.

This is the first time Dong Chen has come here, at this time, Dong Chen is walking and looking at the various data displayed on the glasses, the various materials displayed on the top have been exhausted, whether it is the reagent used to prepare the soil bonding reinforcement solution, or various replacement parts, or the various building materials needed next, Dong Chen needs to transport it here.

It is also fortunate that this place is close to the sea, as long as a tunnel is drilled to the seaside, there will be a steady stream of water available, and then it can be filtered for the solution configuration, and because of the soil reinforcement solution, it also saves Dong Chen a lot of cement, which undoubtedly reduces part of Dong Chen's work, because all these things are to let Dong Chen move out little by little, unless he wants people to know that he has built an underground base here.

Dong Chen curiously walked to the wall and touched the reinforced wall, it felt unusually solid, according to the data, after its strengthening, the soil strength can reach about 70% of ordinary steel, after the soil is strengthened, the color will become slightly lighter than the original color, Dong Chen looked around, and obviously saw that there were several unreinforced places on the side near the ocean, which was set aside for exit.

Because so far there is only one exit to this base, that is, Dong Chen's laboratory, and the diameter of the entrance and exit is still very small, it is difficult to send some parts and machinery to it in the early stage, not to mention the large-scale equipment manufactured in the later stage, it is not easy to do it on land, so you can only find a way towards the ocean.

As long as it extends a few hundred meters into the ocean from here, the water depth can generally reach more than 200 meters, not to mention that after Dong Chen's scanning of the nearby continental shelf, he also found a relatively deep sea rift, and the water depth of the starting point of the sea rift near the mainland alone reached more than 400 meters. This is a sea crack that extends to the ocean due to ancient geological changes, and its side close to the land has formed a short section of cliff face more than 100 meters wide, which is simply a tailor-made entrance and exit for Dong Chen's base.

Dong Chen can also consider developing the shipbuilding industry, directly buy the half-dead small shipyard next to him, and then expand the dock, and directly open an underwater entrance and exit there, and the shipbuilding industry also belongs to heavy industry, and it is understandable to buy it, if the national policy is opened up in the future, maybe it can also contract the country's warship and aircraft carrier construction tasks, but according to the domestic national conditions, the possibility is not very large, unless something unconventional happens.

I just don't know if he only develops and manufactures equipment other than weapons, that is, the entire hull, energy, propulsion, radar, and all other equipment are manufactured by him, and then the corresponding weapons ports are set aside, and all weapons are equipped and installed by the state itself after completion. I don't know if the success rate will be greater.

Dong Chen felt that this matter was promising, after all, this place pursues stability, and all weapons are strictly controlled, but as long as the weapons are not touched, the others are easier to say, it seems that when there is a chance, we should discuss this matter with the bureau. Just thinking about this problem, Dong Chen remembered that the bureau had taken away one of his flying skateboards, I don't know if there is an end of the argument now, or if there are other major things to do, and he forgot about his flying skateboard.

After all, the price of military flying skateboards is not cheap, it can only be used as special-purpose equipment, although the performance is superior, but it can not be equipped by the whole army, it belongs to tactical rather than strategic equipment, and its use is also subject to various restrictions, if you want to raid the opponent's capital, there is no good transport plane to transport you over, then you are also a holiday. So it's really not a big deal for the entire military, for them, aircraft carriers, warships, missiles, fighter jets, etc., that's what matters.

Dong Chen really thought about things more and more, shook his head and dispersed his current thoughts, looking at this empty underground base, how he could transport materials and equipment out of the game world in bulk was the most important thing.
