In a basin near this abandoned base, a large spar mine was discovered, although a lot of it has been mined, but the total reserves are more than ten times more than those in the saltwater lake, and the preliminary estimate is at least more than 50,000 tons. Pen % fun % Pavilion www.biquge.info

After seeing this spar mine, Li Yunfei instantly decided to build a sub-base here, although the Zerg must know the location here, but even if he knew, it didn't matter.

Anyway, the base on the other side of the saltwater lake is also known to the Zerg, so what we have to do now is to use the resources as much as possible to build more combat units, maybe also block it, or even push back a wave or something, there are still a lot of undamaged buildings and equipment in this ruined base, and many places can still be repaired and continued to be used, and the foundation is countless times thicker than the self-made oneself.

Floating at a height of more than a kilometer to observe the environment, the scale of this base can be said to be quite large, and there are buildings within a radius of dozens of kilometers. Compared to here, the base on the other side of the saltwater lake is like a child's home.

It is located on the edge of the desert, and there are sparse grasslands more than ten kilometers away, and even some small animal activities have been seen, which can be regarded as seeing normal animals that do not belong to the Zerg in this world.

Walking around in a range of dozens of kilometers, although there is a ruin everywhere, but also found a lot of good things, although some buildings have been damaged, but the damage is not serious, and there are many equipment that seems to be not very badly damaged, it can be repaired back and reused, of course, even if things can't be repaired, it can also be used for resource recycling.

There are also several half-completed buildings found on the periphery of the base, and these buildings don't seem to have been attacked by the Zerg, so they probably have no interest in destroying these unfinished buildings.

Li Yunfei also floated over, and after careful observation, he found that there was a very special equipment parked on the side of these buildings, which should be a device similar to a construction printer.

It can move freely around the building unit, the direct printing range is huge, the length, width and height are open, and there should be no limit in theory, because it can be moved back and forth and the height is stacked.

Of course, it is only theoretically not idle, in fact, of course, there are still some limitations, as long as the time is enough and the material is enough, it is possible to print a skyscraper directly. In fact, the 3D printer in the real world is still very rudimentary, the material is single, the dome can not be formed at one time, etc., this equipment is nothing more efficient, it can use multi-clock materials at the same time, and it can also complete the printing of the whole building at the same time, which is a kind of basic equipment for construction with a high degree of integration......

In principle, as long as you give a design drawing and provide enough materials, it can be built automatically, and the efficiency is much faster than that of a general robot, and this machine can be powered by natural gas, so Li Yunfei also tried to add half a cubic meter of liquefied natural gas to the gas storage tank of this equipment, and it really successfully activated the equipment that had been suspended for a long time and started its unfinished work.

This equipment uses two materials, a synthetic material in a powder state, and a kind of water, which are extracted in two savings tanks in the distance, and the powder quickly expands dozens of times when it encounters water, becoming a gelatinous substance, and then superimposed layer by layer into the battle of construction, and quickly dries and shapes. Li Yunfei also specially tested the quality of the material, and after a simple test, he came up with a very satisfactory performance index.

The hardness is almost the same as that of ordinary concrete, the toughness is several times that of concrete, and the tensile performance is good.

It can withstand a high temperature of about 2,000 degrees Celsius, and has a good thermal insulation effect, so the material is similar to a foamed porous material, so the material is very light, the specific gravity is only one-tenth of that of water, and the waterproof performance is excellent, which can be called the perfect building material in the phenomenon.

The discovery of this material in the base is already worth the trip, this powder can be called black technology, and the importance to Li Yunfei is almost the same as the technology of faster-than-light flight, and the technology is now useless, and this powder can definitely be converted into the strength of the base in minutes.

I don't know if I can analyze the specific formula of this material from those powders, but Li Yunfei believes that with his own plug-in perception, as long as there is enough time, it is still possible to analyze the ingredients.

As long as you understand the formula of this material, all construction units can use this standard material in the future, get a few kilograms of powder from the powder storage tank, and prepare a good analysis, hoping to figure out this thing as soon as possible, this is definitely a good thing that can trigger a technological revolution. It can be used in multiple Linyu central districts, even if it is a basic structure of aircraft, vehicles and robots that are not key parts, it can be used on a large scale.

"Xiao Wei, how is the situation at the base?" After installing a simple communication tower, it took a long time to debug and finally successfully contact the saltwater lake base.

"It's great to be able to get in touch with you again, everything is working well in the base now!" Xiao Wei had been trying to contact Li Yunfei all the time, and suddenly received the signal, revealing a trace of joy.

"Well, it's okay, what about our losses in this war?"

"In total, we lost only 218 robots, 5,695 automatic machine-gun towers, 130 ground guards on the front line, 2 communication stations, 6 radar stations, camp gas stations, white phosphorus processing plants, ammunition consumption...... Our extermination of the Zerg, 22,320 velociraptors, 1,150 cockroaches, is a huge victory! "Xiao Wei reported the various battle loss ratios in great detail.

"Very well, bring those corpses back right away, you should be able to refine a lot of useful materials!"

"Understand, the corpses of the velociraptor have begun to be collected, 3,351 have been decomposed, the materials of the bones, teeth and bone spurs have been sorted out, and 5 tons of high-quality lean meat have been stored!"

"Well, that's a good job...... But how can more than 3,000 speedy beasts only have 5 tons of meat? How do you dig up meat? "In fact, Li Yun can't eat much of that meat at all, but he is very curious, how does Xiaowei robot cut meat, thousands of hundreds of kilograms of speedy beasts, to make such a bit of meat, it is really a terrible waste, and it is a waste of habits.

"There is a lack of fuel in the base to generate electricity, and the gas station has not been repaired, and the gas storage station has been destroyed, so most of the meat has been put into the incinerator to generate electricity, leaving only the best small piece of meat in the thigh of the Velocitor, do you need to modify the execution order?"

"Well, there's no need to modify it, you're doing a good job, send a few robots over right away...... Forget it, I'll go back and pick up some robots! "Thinking that the movement speed of the robot is too slow, so Li Yunfei still decided to fly back by himself, and it will be much faster to fly the robot directly into the space, as for the transport plane, there is only one that collects the corpse of the velocider and has to rely on it to transport, and there is no air transport for the time being.
