Now all 4 [Ancient Trees] have been promoted, and their energy supply has been restored.

Luo Xin found that in addition to paying for daily consumption and leyline construction, there was a lot of balance every day.

Because there is no specific standard, he doesn't know how many, so he can only [I think] to estimate an approximate value.

It should be quite a lot.

After observing for more than ten days, there is an icon similar to the power display of a mobile phone in the [computer room], which is rising every day.

As for the exact amount of these energies, he himself did not know.

After thinking about it for a few days, he reopened the [refugee tent].

The small goals he had set for himself before had almost been accomplished.

There is a stable, private and suitable environment to live.

The problem of food and housing was solved.

Saved a certain number of his kind, though it was a bit different from what he expected.

Continued the race, and did an excellent job of reproducing offspring.

He felt it was time to shift his mindset away from a survivor of the apocalypse.

Set a small goal, treat the secret space as a business computer game, and develop it into a village and town with a population of thousands.

After thinking about it along these lines, unless the [Teleportation] accident rate problem is solved, the [Refugee Tent] is his only means of farming the population at present.

Otherwise, according to the current population size, if you want to double the number, each couple will have at least two to three babies, and it will take about ten years.

As for the issue of race, there are also human beings in other worlds, and the occupants of the three refugees' glass houses are the best proof of this.

......

A trace of black smoke quietly condensed, and after a while, the continuously converging smoke turned into Luo Xin's form.

It is an underground space made of neat black rock mass, a branch of the sewer line of the residential area that is already taking shape.

It is about 20 meters above the ground.

It is said to be a sewer, but in fact, the area alone is four times larger than that of a residential area, and the depth extends to several kilometers underground, and the highest building on the ground is a 4-link breeding building, with 21 floors and more than 80 meters.

You can see how vast it is by contrast.

In less than twenty days, the main structure of the sewer was generated by the flowing leylines under the precise control of the [computer room]. It only needs to be docked with the sewage outlet of the ground building to complete its basic function as a sewer.

The black rock mass is a mixture of metal and rock, a substance found in the mountain when Qiao Mi built the [Alpine Fortress], which is common on this continent and is difficult to be penetrated by magic, probably some kind of natural anti-magic material.

Although it is an anti-magic material, it is easy to carry it using the leylines, and it is difficult to aggregate it like it is now.

However, a modern ultra-high temperature steelmaking electric furnace solves this problem.

At the same time, another phenomenon was discovered, in which his unique crystal circuit structure was buried in this black rock when it was generated, which produced a filter-like effect.

Different circuit structures affect the flow of certain substances in the leylines, some of which can pass through and some of which cannot pass.

Based on this discovery, Luo Xin figured out an interesting function called [Mineral Precipitation], which can obtain purity minerals with little to no magical energy.

The [Computer Room] can precisely control the flow of the leylines, and can even directly generate various material materials with a purity of 99.99%, but the premise is that a large amount of magical energy needs to be consumed.

There is a similar saying in the aviation industry: as long as the power is strong enough, a brick can fly into the sky.

As for the function of [Mineral Precipitation], as long as the corresponding crystal circuit structure is tested, it is generated inside the black rock mass, and buried in the ground as a building material, and it can operate by itself only by the flow of the leylines themselves, without any additional magical energy at all.

Another purpose of his construction of the sewer was to test this function.

Ordinary sewers are just a few meters above the ground, and he built them 20 meters below in order to get closer to the direction of the earth's leylines.

He [I pondered] 5 kinds of crystal circuit structures, three of which were filtered out as stones without any value, one of unknown value, and the other was a new supernatural ore in China, called magic iron, which was very valuable.

"If you want to get rich, you must first pick up a tree. 』

"I don't have any trees to pick up here, but I can mine. 』

Luo Xin walked in the wide underground passage and touched the smooth rock wall with his hand.

Every short distance from the sewer, there is a street lamp on the wall, which is as bright as in a residential area in summer, slightly dim but enough to illuminate.

It is said to be a sewer, but the width of any branch line is about six meters, and the height is nearly four meters, which is more than enough for two small cars next to each other.

It's more like a national-level underground hub project.

The left and right two meters are pedestrian paths, and the middle two meters are waterways, but all of them are paved with half-meter-thick stone slabs, and there is no problem at all with the view of a 6-meter-wide underground passage.

After filtration, the magic iron ore will emerge from the sidewalk of about two meters like bamboo shoots, and a "mine shoot" with a thickness of half a meter and a length of one meter will take about 15 to 30 days of "growth" cycle.

The black rock mass with the "filter screen" buried inside is not densely arranged together, but only one piece at a distance, and the "mineral shoots" grow to about one meter, which will seriously block the "filter screen" and stop growing.

This has the effect of controlling the internal environment of the sewer and does not block the channel.

"The hardness and toughness of the black rock mass are comparable to that of steel, and when mining the demonite generated above, there is basically no damage, and even if there is, in the process of generating demonite as a material, it can also repair the damaged parts according to the functions set in the crystal circuit. 』

"However, if the internal crystal circuit is destroyed, the function of a whole black rock mass as a "filter material" will be nullified. 』

"The [computer room] seems to have the ability to encode and encrypt magic, and this black rock mass with crystal circuits added to it will only react to the encryption magic of the [computer room] at a great magic level, which is almost close to its carrying limit, and you can consider using this black rock mass as a basic building material in the future. 』

"Hehe, I don't know how to code than I know magic, and I don't know how to program more than I know. 』

Luo Xin walked and stopped, sometimes walking, sometimes turning into smoke and flying, and from time to time threw out a [Identification Technique] to inspect the wall or the ground.

"It hasn't been put into practical application yet, so I don't know what the output is, but [I think] should be able to support an industry with a scale of more than 100,000 people, and if we expand the industrial chain, not only raw materials, but also smelting and processing, this number can also rise...... But the problem is back, this damn teleportation accident rate. 』

"At present, only the crystal circuit structure of demonite has been discovered, and the sewer can only produce demonite ore, and if other valuable minerals are found in the future, the crystal circuit structure can also be produced, and other ores can be produced. 』

"In the future, this should be the pillar industry of the territory...... Hmm? Why do you say territory, it should be a town? 』

"And as long as the leyline exists, this facility will continue to operate, and it can process household waste and even industrial waste perfectly, as long as it does not exceed its carrying capacity. 』

Luo Xin walked down very deeply, and at a crossroads, he condensed into a human form, and after throwing out the [Identification Technique•Change], he finally found a problem.

"Hmm, the oxygen level in the air has dropped, ignore this problem, it seems that it is appropriate to add [Air Generation Module] everywhere...... And speaking of which, such a huge space is only used to process household garbage and grow ore, which is a bit wasteful, and it seems that it is possible to build mechanisms such as sluice gates and dragon stones in some key locations, and [automatic water tanks] and [air generation modules] are also available, which can be used as shelters in case of emergency. 』

"Although the current magic environment is very unfriendly to microorganisms, it seems that this problem has been solved in some areas in China, and by establishing isolated cultivation pools to reproduce the living environment before the disaster, in terms of urban garbage and sewage treatment, this achievement has been done very well. 』

"Well, there's also the need to build some sealed ponds to store biogas. 』

......

"You guys haven't had anything to do lately, help me make a plan for the internal acquisition system. ”

While eating, Luo Xin said.

Son Luo Ping has been learning to eat by himself with a spoon recently, and often makes food all over the table, Sun Lijia eats relatively quickly, and she is taking care of her.

"Huh?" Xu Wenjia just snorted, she was a veritable big stomach, eating like the hamster spirit in the second dimension, her cheeks were bulging, her mouth was full of oil, and there were rice grains at the corners of her mouth.

Even so, the expression on her face is very cute.

Like Luo Xin, she only hopes that the child is safe and healthy, and there is no need to evolve and awaken or anything, and she didn't eat Class A food after pregnancy, it was all ordinary people's Class B and C diets, so the amount of food was even more exaggerated.

Sometimes Liu Jinyu is too busy to do so, and she needs to order it from the canteen in the residential area.

Liu Jinyu wiped her mouth, she ate an ordinary amount of food, but she ate very slowly. "What is the internal acquisition system about?"

I didn't bring my mobile phone with me when I ate, but Luo Xin opened a small rift, took out two of them, fiddled with them a few times, and handed them to the two of them.

The two took it, each slid their fingers on the screen, flipping through the content on it, and Sun Lijia stretched her neck to peek at the screen.

After two glances, she said in surprise: "Mine!?

"Well, I recently repaired sewers in residential areas, which is an additional resource that comes with it. ”

"Demonic iron ore, a new type of supernatural metal that has emerged after the apocalypse, is extremely valuable...... It only occasionally appears when there is an invasion of otherworldly creatures in China, and we have its veins here?"

Xu Wenjia was still eating and eating in her mouth, she felt that Liu Jinyu would ask what she wanted to ask, and the latter looked at the information on her mobile phone and looked up to ask Luo Xin.

"Yes. ”

"What is the expected production and reserves, and how much do you plan to invest? We currently have about 80 million credits on hand...... But large equipment can't be shipped, and your APP can only transport parts about 1 meter ......"

When it comes to mining, the three women subconsciously think that it is a modern mining method in which large-scale tunneling equipment works underground and works day and night on the assembly line, while Luo Xin's expectation is that the transcendent person carries a mining pickaxe on his back and carries a mobile phone on his body, and there is a [transcendent portable APP] in it, using manual mining methods.

The two sides said a few words, and they immediately noticed the difference in each other's cognition, and it took a little time for the family to talk and talk for a while before they unified their cognition, and Xiao Luo Ping in the middle also took the opportunity to babble and didn't know what to say.

"Ah, according to what you say, we really don't need large-scale mining equipment, or even any mining equipment, the strength and physical strength of most transcendents are different from ordinary people, as long as there is a mining pickaxe", Liu Jinyu touched his neck, with a strange expression. "The quarried things are directly put into the mobile phone, even the mode of transportation can be omitted, dug out here, and sent directly to the ground there, and even according to what you said, as long as you integrate your identification technology into this management software, even professional ore identification personnel and mineral processing links can be dispensed without, we just need to keep the acquisition and management department." ”

What Luo Xin asked them to do was not a new mining model, but a management plan, but the new mining method he described was so attractive that the three women couldn't help but tilt their heads.

"In the past, manpower could not match machines, but now that manpower has evolved considerably, and with convenient tools like my husband's [Transcendent Portable APP], we don't need to invest a lot of equipment to produce it. ”

"But this goes against the law of development, and if it continues to develop in this way, technology such as mining equipment will not be developed. ”

"You are talking about the original law of the development of things on the earth, but now that the earth has disintegrated, the new law of the development of things is like this. ”

Xu Wenjia wiped her mouth, swallowed the last bite of food, and joined the discussion.

"Depending on the specific situation, the proportion of extraordinaries in China is not as high as ours, and the environment is said to be much worse than ours here, I mean those supernatural factors, so we can continue to take the route of science and technology in China, and we take the surreal magic route here, there is no conflict. ”

"Why is there no conflict, the equipment manufacturer can't sell the product, this is the conflict. ”

"Now this kind of large-scale industry is supported by the state, and the wartime system is implemented, and we are not domestic, so they can't control us. ”

The three women chattered into a ball, and Luo Xin looked at them with a smile, not stopping this level of interaction.

......

The three women planned an internal acquisition system in a matter of days against prices at all levels in the domestic market.

......

In Luoxin's community, everyone, including the baby, has a mobile phone, even if the baby doesn't know how to use it.

In the beginning, it was given as a benefit to everyone, including volunteers.

The daily basic living allowance, the payment of work remuneration, the payment of volunteer allowances, etc., are all paid by mobile phones on the Internet.

Later, some content was updated one after another, such as external weather forecasts, low temperature storm warnings, domestic news, live broadcasts, videos and other entertainment websites.

It's all Chinese interface, there is no kicking ape here, even if there is, it does not accept interfaces other than Chinese, and if you feel dissatisfied, you can complain casually, anyway, it will not change.

In the past few days, the mobile phone prompt has updated the APP, and after the upgrade, everyone found that there is an additional community map in the mobile phone, and it also has a positioning function.

All of the terrain in the residential area is shown above, even the 50 km radius around the secret space.

However, out of the residential area, the 50-kilometer range is basically a wasteland, although there are no warning signs, but the APP does not recommend residents to go out at will.

Everyone found that in addition to the surface part, there was also an underground part of the residential area.

There is an additional hint here in the underground part, in the future, more expensive magic iron ore will grow here, residents can mine it at will, and the mined mineral deposits are also distributed by individuals, you can choose to buy it for recycling in residential areas, or you can choose to cross residential areas and sell it directly to China.

At the same time, there are also some management regulations, as well as problems and solutions that are prone to disputes in the underground part, etc.

Seeing this, someone immediately couldn't sit still, and according to the map, they found the entrance to the underground part.

At this time, in the various passages of the sewer, on those special black stone slabs, a section of thick and short mineral shoots with a length of half a meter and a thickness of about two feet has grown.

A black slate is three meters square, and there are usually at least six or seven shoots growing on it.

If you have a lot of strength, you can even break a section from the top with your bare hands, and when you put it in your phone, the purity will be displayed, and the purchase price in the residential area will be given at the same time.

And when the first resident, under the gaze of others, submitted the collected magic iron ore, and a moment later, a prompt appeared on the mobile phone that the sale money had arrived, so to speak, the entire residential area was boiling.

Men and women, young and old, who could get enough money, bought a handy digging tool, and those who couldn't get the money to buy a handy tool also used a hammer or a crowbar to make up the numbers.

Anyway, as long as you dig the mine, you will have income immediately.

Even those volunteers from China, after learning the value of magic iron ore on their mobile phones, couldn't sit still, got a tool, changed their clothes, and went down to the pit to mine with three or five people.

The value of the magic iron ore can be compared to the gold before the disaster, and even the richest people don't mind spending an hour or two digging after work.

Who would be afraid of a lot of money?

And the few people who patiently saw all the APP text to the end found that this was a celebration, and within a week from now on, the minerals excavated from the underground place should not be handed over to the residential area to manage the harvest.

After a week, 30% of the proceeds of each mining will be charged, which will be automatically deducted by the mobile app, and when the time comes, you must use a special qualification app software to enter the underground part.

That is to say, it is a carnival now, dig casually, no charge, and after a week, a thirty percent handling fee will be charged, and there must be identity authentication.

Well, seeing this, the last part of the people can't sit still.
