Ning Yu looked through the large number of ships in the starship entry, and was surprised to find that the price of all the ships was not as expensive as Ning Yu imagined. The Ning family's starship plan, just for the construction of the keel of the ship, has already cost 20 billion, plus other various scientific research investments and component research and development, a total of 1 trillion has been invested one after another.

Among the Huang family's goods, the cheapest starship is a space transfer starship, which is only more than 30 meters long, which is smaller than the Ning family's armored transport plane of more than 40 meters when Ning Yu came, and the price is only 400 million. The most expensive starship in the commodity is a capital battleship produced in 2080, and the price indicator shows that it is 110 billion.

At this price, the Ning family's 1 trillion expenses, if they don't have to be on the starship program, can buy a fleet.

In fact, the reason why Ning Yu felt that these things were very cheap was because Ning Yu used the Ning family's financial resources to look at these goods. You must know that the average annual income of the Ning family is more than 2 trillion earth coins, but most of those families have an annual income of tens of billions, and even smaller families have an income of only a few hundred million, and a family with an income of hundreds of billions can already be regarded as a big family. And this is just about income, not counting the necessary expenses, otherwise, many families will be unable to make ends meet, even if the Ning family's annual income and expenditure are profitable, it is only a few hundred billion. Therefore, Ning Yu didn't know that firewood, rice, oil, and salt were expensive, and he didn't consider how much growth opportunities it would bring to the family's R&D and manufacturing capabilities once the Ning family's starship plan was successfully completed.

Looking at the various starships, Ning Yu calculated the 50 billion earth coins that the Huang family owed to the Ning family, and what they could exchange for. After thinking about it, Ning Yu decided to start with the goods that the Ning family urgently needed now.

The first is technology, which is not only the Ning family, but what all families urgently need, but what can be seen on the market is mostly the technology that has been eliminated after the technology of some families has been updated, and even some technologies that have been popularized will be used to mark the price clearly and try their luck. No way, technology is actually the life of a family, you want other people's lives, how can people sell it, even those vassal families also have the right to keep their family's technology secrets to the main family, otherwise once the main family gets your technology, your family may have no value.

For this reason, the relationship between the master and the vassal is actually a buyout relationship, and the vassal's technology products can only be sold through the master or retained by the master himself, and the master pays for the value of these products with his own family's points.

This technology catalog sold by the Huang family is actually the technology that it and its vassal families have eliminated. As it was eliminated, Ning Yu still looked at it seriously, no way, who called the Ning family's main business is gene technology, some technologies are really behind others for decades.

The superconducting material formula invented in 2090, the refrigeration device design in 2084, the self-propelled ion cannon in 2095, the nuclear energy reactor core design in 2091, the space station design in 2089, and the armed frigate in 2084 are all garbage in some garbage. However, after a few hours of filtering and searching, Ning Yu found two technologies that the Ning family had not yet dabbled in, the design drawing of the remote-controlled combat robot in 2094 and the design of the intelligent optical brain in 2096.

Among them, the light brain design drawing, the Ning family needs it the most, you know, now the Ning family's scientific research and the family's central light brain, or the purchased ready-made product, fortunately, the durability of this kind of thing is very strong, otherwise if it is pregnant, the Ning family will have to ask other families to repair it. In addition, if the Ning family immigrated to the universe, the demand for light brains would increase greatly, and obviously this was something that must be able to be made by itself.

The other is remote control robot technology, the key technology of this is space signal transmission and anti-interference, most of the battlefield of the Ning family is still on the ground, using old-fashioned radio signals, and even some battles that are interfered with by signals, will use primitive flags and laser signals to command the battle. This shortcoming has always been a secret within the Ning family, and it is also the reason why the Ning family has always been only keen on defending the territory and not daring to expand aggressively.

The two technologies, after the discount, are about 15 billion in light brain technology and 8 billion in remote control combat robot technology, adding up to 23 billion, and there is still 27 billion left.

After reading the things in the scientific and technological items, Ning Yu looked at the goods in the other entries, the food and medicines in them, Ning Yu swept them away, what are you kidding, these two are the strengths of the Ning family, although food requires a lot of space to grow and cultivate, the Ning family does not have large-scale production, but with the level of genetic science and technology of the Ning family, it is actually very easy to occupy a place in food production. Not to mention the potions, the names of the three major gene families in the universe are not boastful, and every year the Ning family feeds more than 10,000 people in the family just by relying on the income from the sale of potions. However, with the soaring price of food in recent years, the Ning family is also a little tempted by the violence of the food industry.

Materials, components, machinery, production lines are the focus of some production-oriented families, many of the materials of the Ning family are self-produced and sold, only a small amount of armaments and some materials, only need to purchase a large number of materials and components from other families. Models from other families will also not be used for machinery and production lines. And not long ago, the Hua family became a vassal family of the Ning family, which made the Ning family in terms of materials, it is possible to become an export family, which rusty materials may definitely become a popular commodity in short supply in the market, and now it depends on how much output the Hua family can have, but in the end, the use and pricing power of those materials must be monopolized by the Ning family.

Energy, which all families have to store in large quantities, is mainly divided into energy generators and consumable energy substances and energy storage devices, and it is these things that make it possible for humans to use electricity. Electricity is the most widely used terminal energy source by human beings so far, even if the energy utilization in living organisms is also dependent on electrical energy, it can be said that nature is the best teacher of human beings, and electric energy is also the most loyal partner of human beings. In today's troubled times, human demand for electric energy has risen to a kind of madness, and even some human beings have even taken electric energy as a religious worship and established an organization called the "Energy Sect", using the lightning symbol of electric energy as their symbol of faith. Some families who joined this sect also added such a "lightning" symbol to their family crests.

On the screen in front of Ning Yu's eyes, the entries for energy generation devices are divided into several categories: solar energy cells, nuclear energy generators, and wind energy, geothermal, tidal energy, and so on

Photovoltaic cells, which belong to the sustainable use of energy, many families can produce their own light energy films, but the energy utilization rate is different, the photoelectric conversion rate of the best light energy films has reached 60%, but it is still not as good as the use of light by plants in nature. In fact, the Ning family has also been secretly developing a plant that can use light energy to generate electricity, but because there is no suitable base plant, there has been little progress. Moreover, light energy is also one of the main sources of energy in the universe, which can be said to be very important, and the Ning family has paid attention to this point for a long time, so now the technology of the Ning family in the light energy film is still enough, and the light energy film produced by the Ning family itself has even reached 52% of the photoelectric conversion rate, and some of it will be sold to other families.

Nuclear energy generator, that is, nuclear reactor, this requires nuclear reaction fuel to generate electricity, the earliest fuel is uranium, thorium, deuterium, lithium, boron, etc., these are minerals, with a little less precious substance, so the utilization efficiency of nuclear energy generator must be high enough. Even so, the resources are not enough for human extraction. For example, a hundred years ago, humans calculated that the earth's uranium reserves were about 4.17 million tons, but today there are only a few mineable uranium reserves on the earth. For this reason, mankind has to turn its attention to the universe, and all kinds of cosmic mining families have gradually increased, and these families have even invented standard nuclear batteries, they dilute the mined nuclear fuel, fill it into a small miniature nuclear energy generating device, and then trade it to various families in the universe like selling ordinary batteries.

Energy sources such as wind energy, geothermal, and tidal energy can still be used on the planet, but it is difficult to obtain them in space, and Ning Yu did not pay much attention to it.

Energy storage devices, or batteries for short. There are many kinds of chemical, mechanical, biological, physical, and the principles are actually classified into two kinds: one is the fuel cell, which is the combination of energy generating devices and consumable energy substances, and the other is the rechargeable battery, or the device that temporarily converts external energy into a storable and transportation state.

There are many batteries used in various families, and the most widely used is nuclear batteries, but nuclear batteries are fuel cells that need to be filled with nuclear fuel, which consumes nuclear fuel and pollutes the environment. Despite this, standard nuclear batteries have become recognized as standard energy storage devices. Even military energy weapons are standard nuclear batteries, some families in the universe no longer even use earth coins, but instead use this nuclear battery as currency, and some starships are designed to use nuclear batteries as energy sources, which shows its importance in today's interstellar era.

The design of the standard nuclear battery is very ingenious, a standard nuclear battery is like a metal block the size of a lighter, and these standard nuclear batteries can be combined into a 10-unit nuclear battery the size of a mobile phone, 10 10-unit nuclear batteries can be combined into a keyboard-sized 100-unit nuclear battery, and so on, and even combined into a mega-unit nuclear battery used by starships.

In addition, these standard nuclear batteries can be recycled and refilled, and a filler can quickly disassemble the combined batteries and then restack the reloaded batteries into the required combination size.

The Ning family also uses this standard nuclear battery, but the reserves have not been too high, and this time the Ning family has captured a large number of enemy mechas, and the reserves of batteries are even more insufficient. However, Ning Yu will not buy too much this time, because the Ning family has also been developing the manufacturing process of this standard battery, after all, it is a good thing equivalent to currency in the universe, and many big families can make it themselves, if the Ning family can't make it themselves, how dare they call it a big family.

The items after the energy entry are weapons, armor. Ning Yu is most interested in this, the Ning family is civilized with genetic warriors, and the armor and weapons are even more loved by the soldiers of the Ning family.

Ning Yu clicked on the armor parameters one by one, and saw all kinds of armor shapes, and his heart was slightly excited. Some of those armors are very retro in design, some are very sci-fi, some armor pays more attention to multi-functional matching plug-ins, and some advocate simplicity and singleness. There are also some mechanical assistance functions, making it closer to miniature mechas, this kind of armor is mostly the favorite of those families with poor genetic warriors, their value is to make ordinary people can also wear very heavy armor, but this kind of mechanical power armor often has no head-to-head combat power in the face of genetic warriors, you know, genetic warriors wearing heavy armor can even use experience to compete with three-person tall mechas. Ning Yu was happy to see these armors, but he didn't want to buy them, because the Ning family would soon have a more powerful armor, which might be rusty, but it would definitely shock the world.

The weapons column is divided into two categories: one is used by fighters and the other is used by mechs. Here, Ning Yu found something useful. The Ning family's melee weapons have always been made of alloy, relying on the hardness and quality of the material itself to cut and pierce enemies during combat. However, Ning Yu saw a design that uses energy to form a plasma blade at the blade of the weapon in this weapon entry, which obviously improves the weapon's hand-to-hand combat ability and will also cause great damage to heavy armor. Ning Yu really wants to get the manufacturing process of this kind of weapon, but it is not realistic, and he can only buy some equipment troops first, and then let the family's R&D department slowly crack it, although it is very troublesome to crack other families and set up anti-decryption settings on their own products, but the Ning family only spent a few years trying it.

Mechas, tanks, fighters, and the Ning family all use their own standard models, because the supporting facilities can be simpler, and accessories and maintenance will not become too difficult problems. Ning Yu just took a cursory look at this column. However, it was found that today's mecha is becoming more and more varied, in the past, mecha mainly undertook ground combat missions, and now some mecha are specially designed for space landing warfare, and some special engineering mecha can repair warships and build star cities in space. However, chariots and fighters are developing in the direction of simplification, and many families have only one type of chariot, and some families do not have chariots at all. Some families of fighters are the development direction of the integration of air and space, that is to say, many fighters already have the ability to enter and exit the atmosphere like a star boat, and get rid of the gravitational pull of the earth at any time, Ning Yu believes that the fighters will definitely develop in the direction of high-speed maneuver in the future, and now those small power fighters in space warfare will soon be eliminated.
