The world's top technology will never be exhibited in front of the public, but many of the things that are exhibited in front of the public are already very mature. Luo Tian, www.biquge.info pen "Fun", came to participate in the expo not for the most advanced technology in the world, but for those things that have been developed and matured and have been applied in practice.

So far, Luo Tian has not found a material that can completely shield his telekinetic penetration, so the structure and materials of those anti-gravity vehicles on display are basically unguarded against Luo Tian. Of course, the hardware stuff Luo Tian can easily obtain, but the equally important software information architecture Luo Tian can't easily get his hands on it.

The virtual world of data has also been invaded by Luo Tian. However, Luo Tian's telekinesis flow is like a virus to ordinary information equipment, once Luo Tian uses telekinesis to invade the data network, the data will be damaged at least, and the hardware will be damaged at worst. Luo Tian always felt that his telekinesis should be able to gallop in the online world, but he didn't find an accurate method.

The two-hour air show doesn't require the audience to stand all the time to see the end, which is also quite boring. The only thing that really needs to be watched quietly in the audience area is the first 30 minutes of the air show, and these first 30 minutes belong to the five major countries.

After watching the air show of the five great powers, the calm flow of people continued to surge. The air show in the sky continues, and visitors who want to continue watching the show can continue to stop and watch in the audience area; Visitors who want to take a closer look can move to the exhibition area to see the anti-gravity vehicles on display up close.

As for the expo itself, Ye Xiaoman's interest in them is not weaker than Luo Tian's. The difference is that Luo Tian wants to search for the technical information at the exhibition, and Ye Xiaoman and they are just interested in anti-gravity aircraft. Ye Xiaoman: Their interest in anti-gravity vehicles is just as ordinary people were interested in luxury cars more than 20 years ago.

With the continuous development of China's economy, the increasing number of private jets, and the continuous improvement of aviation infrastructure, the low-altitude airspace below a thousand meters above sea level has been fully opened as early as 2020. After the official opening of the anti-gravity vehicle, due to its high-speed and high-maneuverability characteristics, the country quickly opened up professional airspace.

After 2025, registered private anti-gravity vehicles can fly freely in the airspace below 2,000 meters below the true altitude and more than 1,000 meters under the control of the control tower. Of course, in the case that the general public can't even afford private jets, the only ones who can afford to play anti-gravity aircraft are those local tyrants.

Anti-gravity aircraft have replaced luxury cars and private jets, and have become synonymous with local tyrants in the eyes of ordinary people.

When it comes to anti-gravity vehicles, we have to elaborate on their specific classification. According to the maximum ceiling, anti-gravity vehicles can be divided into five categories: ultra-low altitude, low altitude, medium and low altitude, high altitude, and aerospace. Among them, the most common contact with the public is the medium and low altitude anti-gravity aircraft.

The flight altitude of the ultra-low-altitude anti-gravity vehicle is less than fifty meters. There are two main categories: solo aircraft, hoverboards, and flying cars.

In almost all countries, flying cars are not officially allowed to be driven on the road, and can only be driven in professional venues. Flying cars are known as the F1 cars of the new century, and there are special racing events.

Flying cars are mainly popular in Russia, Australia and Canada, and due to the sparse population, a large number of flying racing arenas have been opened up, and it has become a holy place for flying enthusiasts all over the world. Of course, even in these three countries, flying cars are not allowed to be listed on the road, just as there is no country where F1 cars are allowed to be listed on the road.

Low-altitude anti-gravity aircraft fly at an altitude of less than a thousand meters, which is basically the same as the airspace of ordinary private jets. Low-altitude anti-gravity aircraft refers to remote-controlled unmanned anti-gravity aircraft, which are mainly used for logistics express delivery, aerial photography, and simple entertainment.

Remote-controlled unmanned anti-gravity aircraft with a diameter of more than 30 centimeters must be filed with the relevant departments before they can be lifted into the air, and a professional identification locator can be obtained after filing. Once the radar detects an unmanned anti-gravity vehicle that has not been registered, the high-energy lasers distributed in the city will destroy it directly.

The flight altitude of the medium and low-altitude anti-gravity aircraft is less than 2,000 meters above true altitude, but at the same time, the flight altitude must be more than 1,000 meters above true altitude. Medium and low-altitude anti-gravity aircraft are the most popular anti-gravity vehicles of the public, and they are also the mainstream of today's manned anti-gravity vehicles.

Medium and low-altitude anti-gravity vehicles are one of the protagonists of previous international anti-gravity aerospace exhibitions, and they are also the main direction of research for companies and individuals from various countries. Large anti-gravity aircraft have replaced the position of large jets in the civil aviation industry, and the extremely low operating costs of anti-gravity aircraft are incomparable to ordinary aviation airliners.

The flight altitude of the high-altitude anti-gravity vehicle is below 50,000 meters, but 50,000 meters is not its limit altitude. High-altitude anti-gravity aircraft are mainly anti-gravity vehicles for military use, and the maximum flight speed is generally above Mach 8. Due to their extremely high flight speed and overload far beyond the human body's capacity, most high-altitude anti-gravity vehicles are unmanned.

Aerospace anti-gravity vehicles, as the name suggests, are anti-gravity vehicles used for aerospace work. More than 80 percent of the efforts of mankind's aerospace project are spent on breaking through gravity, and the advent of anti-gravity vehicles has completely changed the history of human spaceflight.

The space anti-gravity vehicle has basically ended the absolute hegemony of the launch vehicle in the aerospace field, and the low transportation cost and recyclability have made the space anti-gravity vehicle completely occupy all aspects of the space field in just over a decade.

Of course, there is one type of anti-gravity vehicle that is not among the five categories divided above, and that is the anti-gravity vehicle that is specially used to fight against star insects. Except for the information that the Federation wants the public to know, all information related to Star Worms and Star Gates will not be shared to the public.

The hasty development of anti-gravity vehicles by countries around the world is aimed at covering up the traces exposed by the intensifying confrontation. When there are anti-gravity vehicles flying all over the world, no one cares what the aircraft is used for, and no one thinks whether it is an ordinary passenger aircraft or a military aircraft full of heavy armed robots.

Back at the expo, Ye Xiaoman's liking for anti-gravity aircraft was not so fanatical. After three hours of continuous shopping, by noon, several people were already sweating profusely and a little tired. Only Luo Tian was still as energetic as when he came, and he didn't show any fatigue.

"Luo Tian, let's go back, it's too hot, let's come back in the afternoon when it's cool", Ye Xiaoman wiped his sweat with a tissue and looked at Luo Tian on the side. "Alright, let's go back first." Luo Tian didn't care when he would go back, Luo Tian had already obtained the data of most of the excellent exhibits in these three hours, and the next time he came to focus on the information on paper.
