When the sun retreated among the tall buildings in the west, fishing boats began to return to the port, leaving only a night cruise ship, turned on the searchlights, and sailed along a fixed route. At this time, no one knew what was happening in the sea.

Four meters below the waterline of the Pudong Coast Wave Breakfast Dam, there is a gate, which is covered with seaweed and shellfish, which is exactly the same as most of the cement and rock parts under the waterline of the dam, and there is nothing to be seen. Now the gate as big as a dog cave has been opened, and sea water mixed with a large amount of plankton and algae has poured into the opening of the gate, and then a dark unmanned submarine walked out.

This submarine now represents Luan's exploration of the latest technological level in the sea. As early as Diranfes, Luan's machinery was still pure mechanical transmission. Unhindered film coverage can make mechanical transmission perfect. And as he returns to the main world, his superpower can concentrate temperature differences after further transformation and create ultra-low temperatures in a small area. Luan favors electric transmission.

The reason is very simple. Luan wants to use tools to free up super energy. The mechanical transmission structure requires too much unimpeded film. After attaching it, the super energy must be guaranteed to be on it for a long time. Using equipment to create ultra-low temperatures to cool down various circuits in the machine, the current can run unimpededly in the internal system. Even if the super energy is evacuated in the middle, as long as the low temperature can be maintained, the machine can still operate on its own.

The underwater submarine and high-altitude aircraft manufactured by Luan all use electric conduction technology. This world's normal technology tree, advanced ships and cars also use full electric transmission.

However, Luan uses a fully superconducting circuit. The current is not consumed due to the heat generation of the resistor and is 100% converted into kinetic energy. Luan is much more radical than the people in this world.

Nowadays, normal technology trees have not used superconducting materials on a large scale in machinery. All practical superconducting materials require low temperature conditions. Those room-temperature superconducting materials with extremely large gimmicks cannot withstand the current.

In actual use, the low-temperature sealing problem of the circuit must be considered. This requires that every superconductor be wrapped in a tube, and liquid nitrogen is used to cool it down. If a circuit is added, it will break, for example, the sealing of the tube wrapped outside is leaking. From the perspective of material engineering, this leakage is a normal event. Any plastic will age and cracks in the temperature difference between the inside and outside, and cracks in metal and ceramic materials will definitely break every few times.

If the engineer takes apart and looks at the dense tubes, he will check which tube is leaking and which section is not insulated? This is a fatal matter. It is definitely not a matter of using a pen to measure it at both circuit ends.

Haven't you seen that although the interleaved load-bearing wheels of German tanks in World War II have various advantages in practicality, the complex performance of the interleaved load-bearing wheels was damaged in the maintenance of logistics engineers. After the end of World War II, the tanks of each company were not designed like this.

Now Lu An, who has super power, is obviously incomparable to engineers who rely on two-hand repairs. Super power is much stronger than two-hand repair capabilities. This is why Lu An adopts radical technology. Including this underwater unmanned submarine, it is also different from the orthodox unmanned submarine. Because the coolant of the line cooling device in the submarine is very unpopular.

The coolant in the cooling device is liquid hydrogen. Liquid hydrogen is better than liquid nitrogen, and the price is also very cheap. However, humans must live in an oxygen environment. In this era, all maintenance activities of humans for machinery are also in the air environment, and hydrogen and oxygen will explode when in contact.

The plane of Meng's position, most serious submarine accidents in the world in the 20th century, were caused by fuel cells, fish #mines, missiles, and combustible gas leakage and explosions. This happens to the Russians often. (The remaining few are hit by undersea racing. Cowboys are good at this.)

Therefore, hydrogen should not be used on a large scale in submersibles. However, Lu An is so uncommon because there is no oxygen in the unmanned submersible, it is all hydrogen. When the unmanned submersible is put into the sea, it doesn’t matter even if some hydrogen is leaked. It cannot explode, and only hydrogen without oxygen cannot be done. The manufacturing and maintenance of the unmanned submersible is all installed by robots in transparent engine oil and pure water. Logistics maintenance does not have a great danger.

The only thing that is a bit awkward is that if someone salvaged it and knocked on it with a hammer, the hydrogen leak may burn like a gas tank. So now, Luan is asking the submarine to go out at night so as not to be taken out of the water near the sea by fishermen at night to cause an accident.

A total of sixty unmanned submarines were deployed on a large scale tonight. These submarines were not done anything. From the appearance designed by Luan for these submarines, this is an absolute example of peace. The appearance of the StarCraft God Farmer (Aircraft) is painted black in color due to the cover of sound-silence rubber. The other aspects are exactly the same. Designing this appearance means that Luan did not consider letting these things be responsible for underwater attacks at all.

The activities of these unmanned submarines in groups on the seabed are not harmful to anyone. These unmanned submarines are pumping water flow behind their butts, and quickly approaching the wrecks. After getting close to these wrecks, they extend their robotic hand to approach these marine steel plates and cut with a water knife.

Basically, all the aquatic attachments on a shipwreck can be washed clean with strong water pressure in a few dozen minutes, and then the metal plates can be cut into pieces and packed and taken home.

Of course, there is no danger. Some shipwrecks sinking are caused by ocean currents and reef terrain. Some submarines often break completely when hitting reefs under complex water conditions.

As for this, Lu An, who sat at home and sensed the situation under the sea through a preview, could only sigh.

From the perspective of outsiders, these submarines are not great, they can sail underwater and cut things underwater. They are basically successful works, but from the perspective of Lu An's own use, this is ultimately a random design and copying game models. They are experimental equipment, and the so-called experimentality means that there is room for improvement. The submarine shell, power, and bottom of the water are re-stabilized by the water flow, and the wing paddle design needs to be made after the experimental equipment is used.

A truly complete product should be like a mature industrial product on the market, taking into account the process of the user's use process, no more than more, no less than less.

For example, the beer bottle commonly used by people. The design takes into account the pressure of the bottle, the convenience of transportation and the convenience of use. Therefore, its specifications have not changed for decades. There will be no other strange-shaped beer bottles on the market.

For example, the early iron-clad ships and early aircraft, the early appearance was like a group of demons, but in the later stage, the appearance was almost the same. One more was a burden, and one less was a defect.

However, the thing Luan made now does not have such perfection. Almost as a whole, there are dense areas that need improvement.

In short, the question that Luan is troubled by now involves whether the Black Hawk and MiG who created the Red Alert, or the Banshee and Viking who created the Interstellar world by Yuan Yi.

The air force units in both worlds are designed by designers based on their situation. If they want to use the Earth's gravity and atmospheric environment in Viking, Banshee and Shadow fighter, such aircraft in interstellar science fiction films, will most likely be subject to the Earth's fifth-generation aircraft relying on stealth design and aerodynamic advantages to slap people's heads and suppress them in terms of quantity. Because those fighters that are common in high-tech on other planets are not perfect combat aircraft in the Earth's environment.

Lu An can build various equipment. To some extent, Lu An is now a base car, but cannot improve technology.

This unmanned submarine exposed Lu An's shortcomings. The main world's research institutes have not studied the same type of technological equipment. Lu An explored and combined various technological modules by himself. The equipment produced is full of many points that need improvement. However, thousands of rehears can only integrate existing technological modules, but cannot improve these defective technologies. Of course, if there are 100,000 emotional states, you can do your own experiments. But how much does 100,000 emotional states need to be rehearsed? Lu An is frightened when he thinks about it. So it's better to copy it.

In reality, he fell into deep thought, and Lu An said in a self-questioning tone during the preview: "My closed-door car manufacturing has shown huge limitations. The technology brought from others is ultimately someone else's. After all, it is something that others designed for their own system, and there must be a problem with me to splice it directly." Lu An suddenly thought of the history of the Sanjia's glorious fighter jets on another time and space line. First-class components from all over the world were finally assembled inappropriately.

Thinking of this, Lu An frowned and said, "Do you tell others about my needs and let them design according to my purpose to help me get along with the technical bottlenecks I face.

But what can I give to these people for this? This world is equivalent. Without the ability to give, there is no right to make demands."

In reality, Lu An looked at his palm. His sixteen-year-old palm was very white and rosy in the whiteness. But it was this body that could create terrifying power.

Lu An understands that he represents a powerful force, but through force, it cannot force others to hand over the product of wise thinking. Once the power brings an irreversible gap between the upper and lower positions, it will only cause fear, panic, and abnormal envy to the weaker people, and become stupid, thus ignoring his own ability to summarize, combine and create natural phenomena.

After several tasks, Luan has already summarized two points of human sociology.

1: The liberation of human productivity provides a material basis for more people's thinking (mental labor).

2: The trend of system changes in human society in history is to constantly eliminate all fixed barriers to superiors and subordinates, so that more people have the right to think about themselves.

Under the productivity of primitive society, no one except wizards and chiefs were thinking.

During the Bronze Age, productivity allowed a small number of slave owners to start engaging in mental labor.

In the Iron Age, productivity could allow more people to do mental labor, and more people were willing to do complex mental labor, so they entered the feudal era.

Then there is the era of empire, capitalism, where productivity allows merchants, capitalists begin to think

So much so that in the socialist era, the general population group of the productive working class began to awaken.

However, in the end, human birth will not be labeled with any initial label (poverty and humbleness), and what they do during the growth process define themselves. Then, all people will eliminate low-level interests during their long growth. The sign of adulthood is to develop self-worth of mental labor that is willing to slack off. At the same time, productivity can also afford to all humans to engage in mental labor, which will be the highest social form.

And now, the wisdom of this world is being destroyed by a situation that is inherently powerful.

"What needs can I provide to people in this era? Do people in this era really want what I provide?" Lu An couldn't help asking.
