In this expo, the area of Centaur Alpha is mainly composed of the fantasy Centaur Alpha, the world of crystal worms, the hypergravity planet, biological machines and molecular machines.

Not to mention the first few pieces, what many people can't imagine is that Centaur Alpha actually has advantages in biological machines and molecular machines, and the reason is very simple, the application direction of this field is too wide, so with a slight breakthrough, you can grab a very large piece of the market.

In fact, there are related products on the moon and the mother planet earth, but each has a distinction in content and a bright spot.

Cao Chuan took Joan of Arc to the gate of the pavilion, and in front of him was an ever-updated map of the Star of Hope, on which there were constantly flashes of light, representing the industrial products produced by the factory, and then transported to the airport, and sold through interstellar trade.

They then looked at the products produced around them along the wide corridor, which were very varied, mainly concentrated in the field of biological machines, involving clothing, catering, luggage, department stores, travel tools, hobbies, entertainment, outdoor sports, and games.

"Artificial spider silk? Indeed, with biological machines, it is possible to make high-quality clothing... It is even better than the new clothing introduced 100 years ago, which is simply combined with new technology, and even applied in the military field. ”

The strength of spider silk is 10 times that of steel, in other words, spider silk is a level of graphene molecular level material, plus easy to weave, soft, elastic and so on. But it's almost weightless.

"Yes, yes, theoretically, as a perfect life, I have a way to directly increase the characteristics of the upper part of my skin, and I can achieve my own goals without buying it, although it will become more inhuman. Maybe you can give it a try. ”

Joan of Arc stares at a chameleon's outfit, which is also the product of a biological machine, and by changing colors at will, humans can change their clothes every day without having to buy new clothes.

Not only that, but the greater purpose of the chameleon is to protect itself, and the chameleon clothes have natural optical camouflage and even stealth characteristics. The practicality is also great, and it is also a great attraction for Joan of Arc.

On the Hope Star, there are many companies that develop biological machines and manufacture biological products, and below, they will stay in front of each booth for a while watching all the way.

This is a facility for the production of medicinal ingredients of various natural herbs and medicinal stones. There is no need to work hard to grow medicinal herbs, even if it is a thousand-year-old ginseng. Ten thousand years He Shou Wu can be directly made.

Skip livestock farming, crop growth, and directly produce artificial protein and fiber as food, so that you can ignore the constraints of the natural environment, as long as you can accept the poor taste of synthetic food. Even on an asteroid, you can eat the freshest beef and leafy greens every day.

Cell-scale robots are specialized in debridement and sterilization in the microscopic world, and diseases and infections caused by bacteria will no longer be fatal.

…

Imagine. Even the well-informed Cao Chuan would have taken a fancy to him for such a long time, let alone ordinary people? Therefore, the Centaur Alpha Pavilion can be described as overcrowded, and among the 1 million visitors to the Expo today, 200,000 are concentrated in this area of several square kilometers.

"It's finally out!" When Cao Chuan squeezed out the crowd, he suddenly remembered the World Expo hosted by the Night Rabbit Country that he had visited in 2010, and the scenes of the two were so similar that he had palpitations.

"Let's go see something else." After they rested for a day, Cao Chuan came up with a new idea and planned to go to the pavilion on the home planet, Earth.

In recent years, the East Galaxy Company has undoubtedly been full of presence, making the home planet Earth completely reduced to the role of soy sauce, in fact, the earth, including many countries above, still has a lot of development.

In terms of population, it is still maintained at the critical point of 8 billion, the number of countries is less than a dozen than the original, the total economic volume has not changed much, and the total GDP of 400 trillion yuan is on par with the East Galaxy Company.

But in terms of technology, it is gradually unable to catch up, after all, the rule simulation has made too many super-era technologies that can not be copied overnight, even if the drawings are placed in front of them, there is no economic volume of the East Galaxy Company, and rash research is time-consuming and laborious, and it may not be possible to break through.

In terms of planetary exploration, the most recent incident is undoubtedly Sirius exploration, the local population has grown to hundreds of thousands, and there is no growth for the time being, who said that immigrants have been attracted to the deep space road? However, the pioneers of many countries have infiltrated the deep space road, occupied a lot of wealth, and have hundreds of fleets, which have become the overseas support of many countries.

In the end, the earth has developed 5,000 years of civilization, if you are not confined to high-tech products, there is quite a lot of content on the home planet that can be exhibited, and Cao Chuan does not want the people to really forget where their roots are, and hopes that through the exhibition, more and more people will know these things from the second and third generations.

However, because of the battle with the World Expo, and the distance between the two places is 25 light years, even if there is plenty of time to prepare, the limited number of countries on the earth side participated.

Cao Chuan first looked at the pavilion of the Rising Sun Country, the history of the Rising Sun Country, the industrial rise of the Rising Sun Country after World War II, and the cultural industry of the Rising Sun Country are very interesting, including their exhibition of their small film culture, which is a huge industrial chain that has flourished since World War II, which is well-known all over the world, bringing countless jobs, cultivating countless well-known artists, and exporting high-quality cultural products and creating huge economic value.

Walking around with Joan of Arc, the only thing that made Cao Chuan feel bad was that he was too guilty, but fortunately, there were basically people in the same way around him, and he didn't look at himself with strange eyes, but more envy, jealousy and hatred.

Joan of Arc appeared to be nonchalant, but after a while she still blushed a little, and she could only avoid looking at the mosaic on the screen or the three-dimensional projection, but trying to look around.

There are very few children and teenagers, as a public exhibition, the Rising Sun Country, including the major shareholders behind the company who support the participation in the Expo, has not been undisciplined to the point of public broadcasting, and has strictly reviewed the content of the exhibition, and there are restrictions on the audience's entry qualifications.

Needless to say, if it weren't for the privilege, Cao Chuan would definitely have a lot of trouble going in with Joan of Arc. (To be continued.) )
