[The user [Qiwei] initiated a friend application to you, do you agree?] 】

When Su Chen opened his eyes again, a huge dialog box appeared in front of his eyes.

Agree!

In a daze, he chose to agree.

Zilala~

In the next second, a virtual image was projected in front of Su Chen.

As soon as I looked at it, the virtual image began to become illusory, and I seemed to be very excited.

"Great, Mr. Su Chen, after so many years, I finally met the person from my home planet!"

The virtual image couldn't see his face, but he could feel that he was very excited, and the whole image seemed to collapse with excitement.

"What's the situation?"

Su Chen was a little confused, could it be that after a thousand years, people would not be in Blue Star?

Seeing that Su Chen didn't answer, Qiwei knew that he had scared him, and immediately began to introduce himself.

This virtual image claims to be "Qiwei", and like Su Chen, it is from a human star like "Blue Star".

Qiwei is a space merchant, and the space they are in now is called the Chrono Exchange.

Su Chen listened to his introduction and quickly understood.

It turns out that after thousands of years, after countless disasters and near-annihilation nuclear explosions, mankind finally made several huge scientific and technological breakthroughs and completely jumped into the space age.

And people in the space age are scattered among the planets.

Although the developed technology has made it possible to achieve zero distance face-to-face, in fact, everyone is very lonely.

They may be alone, or two, on a planet, and each of them is really unimaginably far apart.

Sometimes if you want to meet your Blue Star fellows, you can hardly do it, because the Blue Star Fellows are scattered far, far away, and they are scattered, and they are almost impossible to see, and space is too big and too big.

And in space, not only the Blue Star people, but also many aliens from other planets, and people from all planets, when there is a need, they can trade across the galaxy, which is normal.

And the vast space in front of me, which looks like a void, is the Chrono Exchange.

It's not so much an exchange as a virtual space with only two people, face-to-face, and communicating with each other.

The two sides can't see each other's appearance, and can only vaguely know where the other party comes from.

This also gave Su Chen a good platform where he didn't have to tell his origins.

No matter which galaxy or planet he is, as long as he has enough valuable items in his hand, he can trade them, and he can trade them to the technology of a thousand years later.

After a brief understanding, the two parties also officially started this transaction.

"Mr. Su Chen, can you tell me your needs? I should be able to help you find the right product. ”

As a space merchant, Qiwei usually collects a lot of goods, and he can pack a ticket and say that he has no goods that he can't find.

Even if it is an unearthed artifact from five hundred years ago, he can get it, as long as the other party gives a sufficient price.

Under Qiwei's gaze, Su Chen was silent for a long time, and finally put forward his request bluntly.

"Do you have high-temperature materials, or anything related to controlled nuclear fusion?"

"High-temperature resistant materials? Controlled nuclear fusion? ”

Qi Wei was stunned for a moment, muttering about the high-temperature resistant materials in Su Chen's mouth.

"The lowest stage of step-by-step fusion technology, which seems to be the ancient method used to produce energy?"

Then Qiwei asked in confusion.

He was somewhat surprised that fusion technology and applications would be prevalent in some technologies, even in a thousand years from now.

However, high-temperature resistant materials and controlled nuclear fusion technology have long been phased out, and I don't know how many rounds.

In the space age, energy has undergone countless leaps, and such a secondary energy source has long been discontinued.

Just like in the era of communication, no one would use the communication method of flying pigeons to pass books, which is almost primitive people.

From his detailed introduction, Su Chen was able to determine that he did possess this technique, and his fingertips suddenly jumped slightly.

"That's right, that's what I need, I don't know what price?"

Then Su Chen took out a pen from his pocket very casually and played with it.

It's a little habit of his, every time he thinks and ponders, he always holds something in his hand, or a pen, or some other gadget.

In this way, it is very helpful for his thinking.

And now, Su Chen was thinking, for such a low-level technology in Qiwei's mouth, what kind of valuable items did he need to exchange?

"Sir, you, what do you have in your hands? Oh, my God! ”

However, before Qiwei could answer, he saw the pen in Su Chen's hand.

His whole person was stupid in place, and the virtual image almost couldn't bear his emotions, and the four machines were gone.

He's right?

Qiwei's eyes widened, and he continued to look at the precious fountain pen that Su Chen took out casually, and after a while, he screamed and hurriedly took a few steps back.

Qiwei just glanced at it, and he could instantly see the composition of this fountain pen in his glasses.

The shape of this fountain pen in front of me is ancient, and the internal deconstruction is more complicated than other antiquities.

It's clear that it's not just the ancient writing tool.

It is also the middle and upper class in ancient times, used to support status and status, or to collect and play with items.

Qiwei has reason to believe that this fountain pen is definitely stored in some kind of high-level space container that can not be affected by the loss of time. Otherwise, there would definitely not be such a good quality.

Whether it is the material or the loss, it can almost achieve a small loss of 0.0000000009.

It's incredible!

Heavenly creation, real heavenly creation.

This kind of thing, if it can be included in the multiverse museum, it will be another great evidence of human history

How can I exchange such a precious treasure for a low-grade energy technology that is close to the Energy Stone Age, such as a high-temperature resistant material?

Recording doesn't make sense, but recording can make a lot of things more meaningful.

In the time of a thousand years, although human beings have advanced science and technology, they have also lost a lot due to countless disasters, and the most serious loss is the past.

The existence of the past, even if it is just a leaf, can prove many things that are worthy of human nostalgia.

Su Chen was not frightened by his exaggerated retreat, but sensed the cherishment of this fountain pen from his eyes.

"I can tell you that I can ...... with you with this pen."

"Swap?"

Su Chen laughed, stood up and said loudly.
