As Donald took away the forty-five tons of special glass, Wang Bin said to Donald again: "Mr. Donald, do you still need special glass?"

"Yes! Mr. Wang, I definitely need special glass. After all, the war in my world has just begun. In the future, we all want this glass very much for a long time. However, considering that I don't have many energy coins on me now, the amount of glass I can order will not be too much every month. After all, the price of your glass is not cheap." Donald said!

After saying that, Donald thought for a while and said, "Staff owner, if I buy more glass from you but don't have more energy coins to pay for it, am I suspicious to use other means to pay for it, such as using technology or drawings instead?"

"I don't know, Mr. Donald, how much glass you need every month?" After hearing Donald's words, Wang Bin was a little disappointed.

After all, he did not think that in Donald's era, there were any technology and drawings that could be used to offset the price of his purchase of special glass, not to mention that he did not know the regulations of the technology mall, whether this could be done.

So he silently asked the system: "System, please ask, if he uses technology or drawings to replace energy coins as Donald said, can he trade?"

"Yes, but the price of the technology or drawings brought out by the other party must be identified by the system. Neither the host nor Donald himself can identify it. At the same time, the taxes generated in barter transactions will be paid by the store owner!" the system said.

Hearing the systematic explanation, Wang Bin nodded, and then said to Donald: "Mr. Donald, what you said is not impossible, but the specificity depends on what technology and drawings you have taken out. After all, Mr. Donald, you know that the technology level in my world has far exceeded the technology level in your world. If the technology or drawings you have taken out have no use in my world, I will not agree."

"Of course! But please rest assured that many technologies in my world are not behind. After all, each world has its own unique technology, even the same is true for my world.

At the same time, as a plane merchant who can enter the technology mall, I have also purchased a lot of technologies in the mall. I think there are many of these technologies, which are also very important for your world, such as cold nuclear fusion technology," said Donald.

Hearing Donald's words, although Wang Bin wanted cold nuclear fusion technology, he knew that Donald would never come up with these technologies easily. The most important thing is that with their Tiangong Technology's ability, even if he got these technologies now, he would definitely not be able to produce them, because he knew clearly that if he wanted to implement these technologies, he would have to have a relatively complete industrial system and huge financial support.

The most important thing is that according to the system's explanation just now, these technologies generated by store exchanges cannot be compared with those obtained directly from the system. The technologies or drawings obtained from the system are not only the technology itself, but also a series of technology-related knowledge, which will also be instilled into the host's mind together.

The technology or drawings traded by the store are only the technology or drawings themselves, and do not include the knowledge in it.

To realize the technology and to acquire knowledge, you have to learn and implement it yourself.

So even if Wang Bin now has obtained cold nuclear fusion technology, then to realize this technology, there must be a huge team of scientists.

"I don't know how much glass you need, Mr. Donald?" Wang Bin asked. After all, no matter what, as long as he can obtain technology, especially technology that he does not have in his world, Wang Bin doesn't mind using glass to exchange it.

What's more, although Tiangong Technology has not yet established a scientist R&D team, this does not mean that Tiangong Technology will no longer establish a scientific research team in the future.

"Shop owner! I still have a relatively large demand for the quantity of your glass. If possible, I hope to obtain at least 100 tons of glass every month. I don't know if your Tiangong Technology can do it," said Donald.

"Yes, but it will take place next month, because this large-scale glass production line from our Tiangong Technology will not be completed until next month." Wang Bin said.

"Okay! Next month? No problem," Donald said.

At the same time, he is not very anxious about special glass now. After all, for him, the one who needs the most special glass now is their planes.

Now that their large bomber has been manufactured, the demand for this glass will not be that great before the establishment of a new project, that is, before the establishment of a new fighter project production line in their country.

In a month, their new fighter production line will be completed, so the demand for this glass will be greatly increased.

Then, Donald came to his side and said to Wang Bin: "Shopkeeper, this is the payment for this batch of glass, a total of 800 energy coins, please collect it!"

"Okay!" Wang Bin took the energy coin from Donald's hand and looked at it. He found that the energy coin given by Donald this time was also a little different last time. In terms of size and thickness, the energy coin this time was larger and thicker than the one given last time.

At the same time, the color of these energy coins is no longer silver, but a trace of gold. At the same time, the number shown above is no longer 10 but 100. It is obvious that one such energy coin represents the energy of one hundred energy coins. Donald gave him eight such energy coins, which add up to exactly eight hundred units of energy coins. However, Wang Bin knew that not all these energy coins here were his.

Since the transaction amount between him and Donald reached 800 energy coins this time, 8 energy coins will be generated. So he secretly said to the system: "System, don't know how the tax generated is paid?"

Host! The taxes generated by the exchange have been deducted by the system.

Just as Wang Bin finished speaking, he saw that one of the eight 100 energy coins in his hand suddenly changed, turning into 92, and the golden color of the energy coins also dimmed a little.

Wang Bin didn't care about this, but put these energy coins directly into the glass cabinet, and then said to Donald: "Mr. Donald! Donald first, I don't know if you brought the data or photos of your glass you used before. According to our previous agreement, you must give me these usage data."
