In terms of non-metallic superconducting technology, there are problems in production costs and equipment.

Therefore, Wang Bin is more interested in metal room temperature superconducting materials, especially the room temperature superconducting materials with those commonly used metal materials as the core, such as copper and iron. Magnesium, aluminum, etc.

When entering the technology mall system, Wang Bin directly ignored the technology of non-metallic superconducting materials, chose the technology of room-temperature metal superconducting, and chose among the various sub-items inside.

There are also many metal superconducting material technologies, such as iron-based superconducting material technology, magnesium-based superconducting material, copper-based superconducting material, thallium-based superconducting material, mercury-based superconducting material and so on.

However, Wang Bin directly ignored those superconducting technologies that use rare materials or metals as the main materials, because even if Wang Bin bought these technologies, they would still be a bit tasteless to the world he lives in.

Coupled with the use of scarce metal materials as the main material, its production cost must be very high, and the materials are also very difficult to obtain. Even if the basic materials can be purchased from the system in the future, the price must not be cheap, and it is very uneconomical, so these kings Bin basically didn't think about it.

Soon he found iron-based and copper-based superconducting material technology.

Of course, even if it is iron-based or copper-based superconducting material technology, the materials used are not only metals such as iron and copper, but also many other materials. However, compared with the previous superconducting materials based on scarce materials , these superconducting materials are only used in small quantities.

However, compared with those superconducting material technologies based on scarce materials, superconducting material technologies using common metals as the main materials are obviously much higher in terms of price.

For example, the primary superconducting material technology with metal niobium as the main material sells for only 30,000 energy coins in the mall.

However, the primary copper-based superconducting material technology with copper as the main material sells for as high as 45,000 energy coins in the mall, and the price of iron-based superconducting materials is more than 50,000.

Then Wang Bin thought about it, and directly purchased the copper-based room temperature superconducting material technology with copper as the basic material from the mall at the price of 45,000 energy coins.

As for the iron-based room-temperature superconducting material technology, these energy coins in Wang Bin's hands cannot be purchased yet.

Just when Wang Bin had just purchased the copper-based superconducting material technology, Wang Bin's system rang again; "Dear host, congratulations, you have completed all the requirements for the promotion of the technology mall, may I ask if you are interested in the technology mall?" Advance."

After listening to the words of the system, Wang Bin finally breathed a sigh of relief. In fact, the reason why Wang Bin was so eager to buy technology was actually for the promotion of the system.

After all, at the first level, Wang Bin can only purchase primary material technology in the system.

As for other technologies. He can only get the technology he wants from the hands of his customers, and even if he gets the technology, he must implement these technologies himself, and he cannot directly put the technology into his mind.

But after reaching the second level, the technology that Wang Bin can purchase in the system is not just material technology.

At the second level, in addition to continuing to purchase material technology in the system, Wang Bin can also purchase various raw materials that can be found in nature in the system. Most importantly, at the second level, Wang Bin can use the system to purchase On to some real tech stuff.

So he immediately opened the system and checked the things he could buy. He found that the prices of these raw materials in the system were calculated to be similar to the real prices.

However, it is extremely uneconomical to use energy coins to buy some commonly used materials that are easy to buy in reality, such as steel.

However, if you use energy coins to buy those scarce materials in the mall, it will be different. First of all, although there are very few scarce materials in the real world.

But it is different in the civilizations of other universes,

Maybe in a certain world, there are such materials everywhere.

Therefore, no matter what materials are in the mall, even in the real world, the raw materials that are extremely rare on the entire earth are in unlimited supply in the mall, but the price is a bit high.

After reaching the second level, the system has much lower restrictions on the products sold in the technology mall.

The products sold in the technology mall before must be 100% products produced by Wang Bin and Tiangong Technology itself.

At the same time, in terms of technology, it must be designed by one's own factory or purchased from the mall system before it can be sold in the system.

Now, this limit is much lower. Except for the product technology itself, which must be designed by itself or purchased from the system, the restrictions on product production are not as strict as before.

As long as a product is the core component plus more than 50% of the accessories and is produced by its own factory, it can be sold in the technology mall.

So when Wang Bin saw this, he was very happy. After all, it was fine before, it was just the basic material technology, so except for the raw materials, in the smelting process, all the processes were completed by himself, and there was nothing wrong with it.

But it will be different in the future. In the future, Tiangong Technology will produce more and more products, the technology will become more and more complex, and the internal parts will also increase. Therefore, they cannot produce all these parts by themselves. .

The most important thing is that according to the rules of the system, if more than 50% of the shares of a company are acquired by Wang Bin, then the products produced by this company, as long as the blueprints or core technologies are provided by Wang Bin, then Its products can also be sold in the system.

In addition, after reaching the second level, Wang Bin can purchase a lot more technology, except that he cannot purchase the key technology for civilization upgrade from the system.

For example, controllable nuclear fusion technology, large spacecraft technology that truly has the ability to travel within the planetary system for a long time, anti-gravity and artificial gravity technology, etc.

Because according to the regulations of the system, if Wang Bin wants to purchase these technologies.

Then Wang Bin must upgrade the system level to level three, and the most critical indicator for upgrading to level three is to raise the technological level of human civilization to above level 0.9.

In addition, more than ten technologies must be purchased in the system, and these technologies cannot be basic material technologies, and the price of each technology cannot be lower than 100,000 energy coins.

In addition to these, there is another most important indicator, that is, the factories owned by the host must have the ability to manufacture small and medium spacecraft in the planetary system.

After reading all this, Wang Bin knew that in a short time, he had nothing to count on.

So he turned his eyes to the technologies he can buy now, and he found that there are many types of technologies in the system, covering all the technology categories of the entire human civilization, from the simplest to the most advanced. Basically everything can be found.

At the same time, in terms of price, like the previous material technologies, those simple and backward technologies are not worth much in the system.

Take ordinary paper production technology as an example, the price in the system is only one energy coin.

But if it is the world's top paper production technology, the price will be as high as several thousand or even tens of thousands of energy coins.

Of course, if it is the paper manufacturing technology that exceeds the current level of human civilization, then the price will be higher, at least calculated in ten thousand energy coins.
