Chapter 41 (2/2)

Although there are many stores selling various products in this area of the whole technology mall, many of these stores, or the technology level of the owner's world, are not very good. Even the technology level of most of the things sold by the stores can not reach the world level.

Of course, it's not a world without high-tech level, but these stores basically don't sell basic materials. Even if they do, there are only one or two kinds, and the price is even higher.

Or sell some products that are useless or difficult for them to understand, such as chips that are very difficult for him to understand, and even those that don't know their purpose.

The most important thing is that in his opinion, the price of things the size of a matchbox is higher than that of many large commodities, which makes him too difficult to accept. What makes him more difficult to accept is that people still buy such products, and many people buy them.

The shop called Tiangong technology is much better. From the glass in the shop, we can see that the technology level of the owner's world is absolutely extraordinary, which is not comparable to his world and country.

Take these glasses for example. After he bought them last time, he returned to his world to test them and even reverse deduce them.

As a result, even the raw materials used in these glasses cannot be fully recognized in their world, let alone imitated.

Although the price of the glass sold in this shop is not cheap, it is better than other shops, and these glasses have many uses.

Now that the store has other new products, he naturally wants to see whether these materials or products play a role in his world and country. If so, he doesn't mind buying some.

While Donald was thinking about this, he followed Wang Bin to a container. Then the owner of the store took out a glass object similar to the screw from the glass container and said, ”Mr. Donald, that is the new product launched by Tiantong technology, high-precision ball screw.”

”Ball screw?” Donald was obviously surprised when he saw these ball screws made of glass. Donald was no stranger to ball screw in his original world as a scientific and technical personnel. After all, ball screw had appeared in his world or era, although not many, but not strange.

To his surprise, these ball screws were made of materials.

”Sir! Can these glasses be made into ball screws?” Donald asked.

”Yes! These special glasses can be made into many things, including ball screw,” Wang Bin replied.

As Wang Bin spoke, Donald began to carefully observe these ball screws and also looked at the data of these screws made of glass in front of these screws.

After Donald began to observe these screw rods, Wang Bin stopped talking and waited quietly.

After a long time, Donald looked up and sighed to Wang Bin, ”shopkeeper, these screw rods are really great. They are simply handicrafts!”
