In the Yuanyi space, Lu An looked at the pedestrians on the street, and then silently exited the space. At this time, the space was only a few repetitive minutes for Lu An, and when a few minutes passed, he was forcibly kicked out of the space.

Therefore, the Yuanyi space still existed for Lu An, and in those nine minutes, Lu An could rummage through what color was under the skirt of each female space-time mercenary. But after nine minutes it was all gone.

What happened nine minutes ago? Lu An can't see it, and can only guess from the traces that have existed in the space,

What will be posted in nine minutes? Lu An could not see it either, and could only speculate from the existing situation.

"A small pond of information, the size of the pond is nine minutes" Lu An said after entering the space for the ninety-fourth time.

However, this sentiment is only the beginning.

"In this pond, all the space-time mercenaries may be strong and weak, but this doesn't matter to me anymore, every space-time mercenary has a story behind it." After entering and exiting the space for the 111th time, Lu An felt this way.

When the perspective is limited to a short period of nine minutes, the eyes focus on those who are no longer marked by power. In the face of time, strength and weakness are meaningless, compared to those powerful space-time mercenaries who explain their smooth adventures, Lu An is more willing to read the twists and turns of those weak space-time mercenaries in the mission.

After entering the space for the 172nd time, Lu An figured out the work, occupation, outlook on life, values, and feelings of the 627 people before entering the space.

After two hundred and sixty-three times and re-entering this space with only nine minutes of time, Lu An could no longer determine that in Yuan Yi's perspective, that person should be the protagonist, and that person should be the supporting character who will be sacrificed in the next mission. Because everyone's experience seems unique.

Three hundred and sixty-seventh times.

Four hundred and twenty-fifth

Six hundred and thirty-seventh.

……

The more you know, the more confused you become. Today is the seventeenth time that Lu An has withdrawn from space, and if there is a small pond with limited boundaries in the space, then the main world at this time should be a sea.

The passers-by who come and go downstairs, each one seems to have a story behind it,

At this time, Lu An, who was standing on the balcony, couldn't help but stretch out his hand in reality, but after raising his hand, he couldn't help but feel a little confused, which one to talk to in the rehearsal. At the same time, I understand that most people will never be able to understand their unique experiences.

The powerful Unhindered Super makes Lu An feel that he is fortunate to be able to touch more rules in this world, but strength is not everything, especially for a space-time mercenary like himself, an improper display of power will make him miss a lot.

Lu An looked at the stars in the sky, and Lenovo Yuanyi promised himself that he could freely choose the next world.

Lu An smiled and said, "I need the ability to look around in this world, and I also need people who accompany me to look around." So in the next life, I decided not to choose the world of Xianxia, gods, magic, and Xuanqi, but to choose the world where I didn't seem to have any strange abilities, but actually made me feel ignorant.

As for now I will be this (super), dig deep to the extreme. So that I can do something else in the next world. ”

While Lu An made the above impressions, he also confirmed this feeling for himself in different emotional states in each rehearsal. And from a huge vantage point that allows you to see through the entire city.

At this time, hundreds of rehearsals were flashing at the 600 meters under Lu An's feet. Most of the rehearsals were hyped up with data from camera perspectives, but there were still sixteen rehearsals that went underground in person.

When Lu An designed this underground production system, he found that he had no chance to go down in reality. I will only run down in the rehearsal, and in each rehearsal, this underground production system will go down alone.

Therefore, this underground production system does not need to be considered for a large number of workers to live for a long time, so the carbon dioxide concentration in the entire underground area has been increased to more than 90 percent, and the design only needs to place enough oxygen cylinders and oxygen masks to ensure that Lu An is safe in the rehearsal.

The high concentration of carbon dioxide eliminates the risk of combustion after many industrial manufacturing, and also eliminates biological interference, not to mention people walking into this area, even rats cannot enter, one of the main purposes of Luan is to prevent rats from biting their own electronic circuits.

Luan's ability to destroy all tall buildings within a three-kilometer radius in three to four seconds is no less destructive than a nuclear bomb (by knocking down the base load-bearing walls of all buildings), but it was annoyed by rat biting lines a few months ago, and rats bred from the city's sewers followed several entrances to and from Luan's underground industrial production, and then entered the drill hole and used the thread inside to grind their teeth. For a while, Lu An pondered whether to continue to replace the mechanical energy circuit with a zero-resistance circuit.

However, as a result, it was solved, and now there are no cockroaches in the underground area.

The entire underground space is filled with carbon dioxide gas, which also facilitates Luan's use of superconducting materials.

The world's scientific and industrial world, obsessed with the development and mass production of superconducting materials in the liquid nitrogen zone (helium is too expensive and non-renewable), Luan is arrogantly using liquid hydrogen as a coolant in his underground space. The massive, underground-based power system consumes three to four tons of liquid hydrogen per day to cool the superconducting pipeline. Maintain the zero resistance of this power system. The electricity used to produce hydrogen comes from geothermal power generation wells, so it is basically a self-sufficient system. All Lu An has to do is send robots with cameras to check if the systems in each area are normal. The rehearsal that required you to put on your own spacesuit only took 200 to 300 times a day.

The entire underground system can be said to be a complete scientific and technological system, but it is impossible for normal people to design this scientific and technological system, because it is difficult for normal people to maintain this scientific and technological system, and if normal people go down to maintain it, at least thousands of people need to control the robot on the post to check.

In addition, if the person in charge of preparing the spacesuit is negligent and does not prepare enough oxygen for the inside, then it is dangerous for the person who goes down to maintain it. In order to reduce the risk, the person in charge of this series of links must have a high sense of responsibility, take the trouble to check every day, even day after day, year after year, will not find problems, and must meticulously do this seemingly meaningless work every day. Therefore, normal people will try to eliminate this tossing link.

From the macro point of view, Lu An's system is like a big net, a very sparse net, even if there are traversers who have learned the art of earth escape, they are not afraid of touching gas pipelines and sewage pipes, and they can drill underground to their heart's content, but it is difficult to touch the wires and pipes arranged by Lu An fifty meters underground.

However, this large net is like a tumor in places, and different production areas occupy a lot of underground space, which is divided into several layers due to the different temperature and humidity environments required for different production and processing. There is a steelmaking area in the building where Lu Ann went to school, and the forging of various steels occupies different areas.

At this time, there is also a system under the Luan residential building, which is now consuming a lot of electricity, and beams of lasers are being focused and ignited at a high density. The latest system is controlling the laser to irradiate multiple lasers at the same time in the femtosecond phase.

In the experiment under normal physical environment, with the intensive irradiation of multiple lasers, not enough energy has been gathered, and the matter focused by the laser is blown away due to other effects derived from high temperature, which fails to further impact the next reaction and release the deeper energy bound by the stable material structure. For example, what can be released by the polymerization of deuterium particles. However, under normal physical conditions, the energy density is insufficient, resulting in the inability of the reaction to proceed.

But what if you change a physical quantity, or let a special physics cover its reaction range?

Experiments were underway underground, and in the nearby production hall, the parts of precision clocks were being forged simultaneously, and Lu An, who was standing on the balcony on the ground and looking up at the stars, smiled.

"In this world, I can't call out to my companions, at least I can make the starlight bloom in the palm of my hand, can I?" A certain emotional state said with a smile in the sea breeze.

The camera cuts to the northeast of the sea, and the island nations of Northeast Asia are also entering the night. Viewed from space, the island nation of Northeast Asia is very densely lit, which is a symbol of prosperity.

Some people always say that the island countries of Northeast Asia are short of resources, but in this era of peace, this is a fallacy. In an era of global stability, the island nations of Northeast Asia have the resources of living in the envy of Iran, Russia, and Europe. Yes, the world's most valuable land is not the land where oil is buried. If a piece of land the size of one-third of Jiangsu (the size of Taiwan Island) is suitable for 20 million people and can support 20 million people to maintain a high level of education, this is actually much more expensive than hundreds of large oil fields. Taking the above house price as an example, the value is higher than that of the oil field on the bright side.

In times of peace, the well-educated population is the country's greatest resource. In the cities of this island nation, a large number of fine industries are produced.

Focusing on an area of Tokyo Bay, this area looks like a factory for the production of canned fish, but below the factory is a high-tech experimental base, where researchers in chemical protective suits are busy.

In the control hall of the base. Uda stood in his seat, looking at the screen hanging in the center of the hall. And the shallow space in the uniform of a snake cadre is sitting leisurely on the seat with black silk legs crossed, holding a box of sweets in his hand, and elegantly sending it to his mouth with a spoon.
