In the middle of the empty hall, there is a circular service desk, above which hangs a projection screen, and on a large screen there is the overall layout and route map of the entire library. There are small screens at the service desk, no staff, and no service robots.

Tang Yunfeng came to the service desk, and the small display screen in front of him lit up, and he found that the small screens were service robots.

"Welcome to Tian Yuan Library, how can I help you?"

"I want to know about the history of the Tianyuan Universe."

"The history books of Tianyuan Universe are on the first floor, please go by yourself."

While the service robot speaks, the screen shows the location of the sub-area on the first floor, as well as the route map from the service desk to the sub-area. Tang Yunfeng took a look at the overall layout and single-story layout of the library, and found that each floor of the circular library was divided into twelve districts, corresponding to twelve hours, and was named after the twelve earthly branches "Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai". Each district has a total of ten rows of bookshelves from the inside to the outside, named after the ten heavenly stems "A, B, C, D, E, G, xin, non, and dec", which is extremely traditional Chinese culture.

According to the route instructions of the service robot, Tang Yunfeng came to the bookshelves in the sub-district, which had four floors and was more than one person high, and each layer was full of books. The title of the book numbered 1 is: "A Brief History of the Tian Yuan World", followed by "The History of the Creation of the Tian Yuan World", "The History of Environmental Changes in the Tian Yuan World", "The Hydrological History of the Tian Yuan World" and so on.

A metaverse virtual space actually filled a bookshelf with history books alone, but Tang Yunfeng was not interested in these, he just wanted to understand the basic composition and basic rules of the Tianyuan Universe. He has always had the view that the metaverse world is the embodiment of scientific and technological progress, which is conducive to scientific and technological experiments and the spread of civilization, but this thing is just like a laboratory, he is just a tool, not the real world after all.

He couldn't understand that some people invested a lot of real money to buy the virtual land of the so-called metaverse. You must know that the metaverse was still just a prototype at that time, without any national and official support and endorsement.

Virtual things are nothing more than the number of participants and social recognition. Some metaverse operators are similar to the early blockchain decentralized currencies such as Bitcoin and Ethereum. It is to throw out a concept for everyone, and to play is a concept dressed in high-tech technology.

As it turned out, he was most right. Some of the metaverse eventually became a sickle for capital to harvest leeks, and the operators went bankrupt and ran away, leaving investors who are crazy about the virtual assets of the metaverse with chicken feathers.

Whether it is blockchain technology or metaverse technology, it is a good technology that has emerged in the development of human civilization, and the key is where it is used. Kitchen knives are not guilty, and those who are guilty are those who use kitchen knives to do evil.

Tang Yunfeng remembers that when blockchain currency was at its craziest, some people compared it with national fiat currency, and also listed the advantages of decentralized currency over national fiat currency. Yes, to a certain extent, the national fiat currency is also a virtual thing, but the bad thing about this group of people is that they deliberately ignore the fundamental logic of a currency. Currency is the embodiment of equivalent exchange, and the national fiat currency is backed by national credit and national assets. What about decentralized virtual currencies? Endorsement with technology!? Technology is constantly advancing, once a new technology subverts the existing technology, or the holder of the existing technology modifies the underlying logic of the technology, what is left of the virtual currency? There is nothing left.

It is undeniable that there are also many national fiat currencies due to the bankruptcy of national credit, resulting in money not as good as paper. But after all, this situation is a minority, and it all happens in some small countries that are in turmoil, and the national credit is basically non-existent.

Tang Yunfeng believes that the situation of these small countries is the true reflection of the virtual currency group, when there is a breakthrough in technology or the underlying logic is modified by the technology holder, the fate of virtual currency will be exactly the same as the currency of which countries have collapsed credit. The only difference is that investors in virtual currencies are voluntary, and the people of those countries do not have a choice.

The reason why he wants to study the Tianyuan Universe is because "Tianyuan Universe" has the joint endorsement of all countries in the world. This means that this is a virtual world with the credit endorsement of all countries in the world. Although the world still cannot solve the problems of poverty, hunger, disease and environmental degradation in the real world, it can meet the spiritual, social, and learning needs of most people. With enough audience and basic services, it has a certain real value. For example, Tang Yunfeng himself, this world can meet his normal exercise needs and facilitate learning.

Pulling out the "A Brief History of the Tianyuan World" from the bookshelf, Tang Yunfeng opened it easily, and the book automatically turned into a projection screen with the visual texture of real paper. Through his flipping book, he began to turn the pages, Tang Yunfeng briefly browsed, and the book mainly introduced the original intention and main participants of the construction of "Tianyuan Universe", as well as the underlying logic and social rules of Tianyuan Universe.

Tang Yunfeng didn't look carefully, and after putting the "A Brief History of the Tianyuan World" back on the bookshelf, he strolled around the library. He was very happy to find that this library has collected almost all the books in the real world, and they are all well-edited authoritative editions, and he finally doesn't have to spend too much time on the road to read books in the future.

After a cursory walk, Tang Yunfeng came to a quiet place and began to call for discipline Xiaofeng through his Tianyuan bracelet. The Tian Yuan bracelet is automatically generated when the player enters the Tian Yuan Universe, which has all the information of the player on it, and is also the most important tool for players to pass in the Tian Yuan Universe.

The bracelet popped up a projection screen, and the figure of the housekeeper Xiaofeng appeared on the screen.

"Dear master, what are your commands?"

"Help me open a portal home."

"Okay, please wait."

After a while, the projection screen of the bracelet turned into a watery door, and Tang Yunfeng stepped in and returned to his room in apartment 1702.

He took off his clothes and lay down on the bed, clicked the red button on the Tianyuan bracelet, and the gentle female voice of the intelligent system sounded.

"Tang Yunfeng, are you quitting the Tianyuan Universe?"

"No, I pressed the wrong button."

"Okay, have fun."

Hey, there's really no BUG! Tang Yunfeng put away his prank, pressed the red button again, and the gentle female voice of the intelligent system sounded again.

"Tang Yunfeng, are you quitting the Tianyuan Universe?"

"Exit, okay, please wait."

A ray of light scanned Tang Yunfeng from head to toe.

"Iris confirmed, bracelet confirmed, player identity confirmed, do you confirm exit?"

"Confirm."

A white light flashed in front of him, just like the light at the time of landing. Tang Yunfeng's eyes appeared in front of the cosmic starry sky at the time of the earliest landing, and the female voice of the system sounded in his ears again.

"You have exited the Tianyuan Universe, have you exited the landing module?"

Exit

"Please wait"

The scanning light on the helmet rotates again to scan.

"The surroundings are safe and you can exit. Welcome to the Sky Universe landing pod, see you next time. ”

In the "goodbye" sound of the gentle female voice of the system, the VR glasses shrouded in Tang Yunfeng's eyes automatically and slowly lifted, allowing his eyes to adapt to the outside light. At the same time, the inductive material of the landing module began to be pumped out, and the landing module was like a large balloon slowly deflating. After a while, it was back to its original sleeping bag.

Tang Yunfeng pulled out his arm and took off his helmet, squinting his eyes to adapt to the light outside, and what appeared in front of him were two heads with round eyes. If he hadn't been brave, he would have been really startled by these two anxious guys.

"Brother Feng, how is it?"

Han Fengxiang asked impatiently.

"You two step back, let me sit up and talk."

Han Fengxiang and Li Xuhui immediately stepped back, and Han Fengxiang also helped Tang Yunfeng up. Looking at the eager eyes of the two people, Tang Yunfeng finally knew how his fathers' Internet addiction came about.

"It's a real feeling!"

"How real is it?"

"It's like being in the real world."

Tang Yunfeng told the two of them about his experience in the Tianyuan Universe in detail, and didn't want to envy the two of them.

"What a pity?"

After Li Xuhui was excited, such a sentence suddenly popped up.

"What a pity?"

Han Fengxiang and Tang Yunfeng both looked at him curiously.

"I still want to find a daughter-in-law inside, according to Brother Feng, I can't do anything to find a daughter-in-law!"

"I grass, you filthy, shameless, nasty thing, I said, why do you like to play assassins so much?"

Han Fengxiang strangled Li Xuhui's neck, slapped him indiscriminately, and looked at the two people who were fighting next to him, Tang Yunfeng also laughed happily on the side. This guy's mind is really dirty, but he really likes this atmosphere.

The two of them quarreled for a while, and Han Fengxiang suddenly asked:

"Teruko, you won't be without a girlfriend, will you!?"

Li Xuhui's face flushed, and he said timidly:

"I have had a girl I liked, but unfortunately people don't look down on me."

Han Fengxiang laughed exaggeratedly: "I said, why do you always want to find a daughter-in-law in the metaverse, you have been hit by reality for a long time!" ”

"Damn, talk like you have a girlfriend!"

"I don't have it, we martial arts practitioners, we must ensure that Yuanyang is not lost, and we can't get close to women until we get home."

"Cut, if that's the case, I think you'll have to fight for the rest of your life."

Li Xuhui hit Han Fengxiang without showing weakness.

"Hehe, Teruko, you're going to be disappointed! Young Master Ben is a genius in martial arts, according to my grandfather, I will be able to break this level in less than three years, and there will be no taboos at that time. ”

"Hmph, the premise is that you look like a bear, and you have to have a girl like it."

"That's better than your round body, too."

"Fuck off, Lao Tzu, is this baby fat?"

"Baby fat, you have a face, you have seen baby fat."

The two of them were arguing happily, and found that Tang Yunfeng next to them had been looking at them with a smile, his eyes were wandering, and his thoughts had long been unknown where to fly. The two of them immediately stopped, and Li Xuhui stretched out his hand and shook it in front of Tang Yunfeng's eyes. Tang Yunfeng's eyes instantly focused, and his thoughts were obviously retracted.

"What?"

"Hehe, Brother Feng, we two single dogs, judging by sharp intuition, you have a problem. Tell us the story of you and your sister-in-law, and let us learn. ”

Li Xuhui came to Tang Yunfeng's side awkwardly.

", there's nothing to say to you."

"Well, I'll just say something is wrong! There really is. ”

Li Xuhui said proudly to Han Fengxiang.

"Brother Feng, let's talk about it!"

"Don't say it?"

"Tell me about it!"

"Fuck off, you two disgusting guys"
