Speaking of cross-border challenges, it is necessary to talk about the state of society today. With the development of society and the advancement of science and technology, megacities have begun to rise. In some newly developed living planets, and many extraterrestrial civilizations, there are often only one or two cities on a planet. A city can be hundreds of thousands, or even millions of square kilometers, and a city is a country with more than billions of people.

Although there is no such extreme on the earth today, there are only more than 100 cities left on the continent today; And with the city as the administrative center, a new political system was established. There are hundreds of thousands of square kilometres of land around every city – but almost all but the necessary farmland has been returned to forest.

In addition, after the interstellar environment, due to the mutual invasion and infection of viruses and microorganisms, many organisms have mutated to a greater or lesser extent. There is nothing about biological mutation, after all, this is a high-tech era, and even if there is a dragon, it can be beaten down from the sky. But for most ordinary people, even ordinary wolves are dangerous creatures. This has also indirectly contributed to the process of urbanization.

There are more than 100 cities, each with a population of 10 million, and even more than 50 million, and a city will have more than a dozen middle schools; In such a situation, middle school students who can take on cross-border challenges can be called dragons and phoenixes among people! That's definitely the ruthless, elite and academic tyrant who beat the invincible opponents in their own city. Such people do not exist every year or in every city, but every time they come out, they are all people who can attract national attention. In the future, as long as there are no major problems of principle, it will be appropriate for the state to focus on cultivating talents.

While the average elite middle school students began to challenge in reincarnation, these elites had already leveled the middle schools in their cities and began to challenge external expansion! Moreover, Puhai City has always been a big city, and what came out of Puhai City was a tiger descending the mountain and a dragon entering the sea!

So when they heard that it was a cross-border challenge, everyone gasped! Even Zhang Yunqiang's complexion changed suddenly! Those who are qualified for cross-border challenges must be the elites who have awakened their spiritual power in advance, otherwise they will not have an absolute advantage to sweep the opponent! Without borrowing scientific and technological means, he awakened his spiritual power, and they are all little supermen!

There is no shortage of geniuses in this world, especially in this era!

After adjusting his emotions a little, Zhang Yunqiang actually regained his self-confidence, but he also generously admitted defeat: "Qin Fei, I have already lost the competition just now." Now, please represent Yunhe City! ”

Teenagers in the new era are smarter, wiser and more rational, and under normal circumstances, they have their own judgments - by the way, they can also pull a person into the water. For example, right now, Zhang Yunqiang not only took the initiative to admit defeat, but also dragged Qin Fei into the water by the way-buddy, you should fight for Yunhe City.

Qin Fei didn't look at Zhang Yunqiang a long time ago, but looked at Xu Weisong. Both of them had a glint in their eyes, and they were obviously geniuses who had opened their spiritual power.

Spiritual power is a non-material extension of life, mainly intelligent life! It is the change and derivation of the magnetic field of life. It's just that the mental strength of ordinary people is very weak, and they can barely maintain the needs of life.

"Yes, I didn't expect there to be an elite like you in Yunhe City!" Xu Weisong's arrogance is deep in the bone marrow. has been a genius since he was a child, enjoys all the treatment of a genius, and his family conditions are also very good, so it is normal for Xu Weisong to have such arrogance!

"I'm afraid that someone will be overconfident! Beware of falling too hard! Qin Fei raised his head slightly. As a genius, Xu Weisong's arrogance is manifested on the surface; But Qin Fei's arrogance is deep in the bone marrow - he can't see it from the outside, and he won't show it in front of ordinary outsiders, so it's really unnecessary; But if you meet "the same kind", this arrogance will be stimulated!

The two seem to be cross-eyed, you look at me, I look at you, but the people around them can faintly feel a kind of pressure; This kind of pressure is like an ordinary beast encountering a lion and a tiger.

"Very good, you deserve my shot!" The two looked at each other for a long time, and Xu Weisong was the first to speak.

Qin Fei raised his eyebrows: "Let's say, physical arts, scientific competition, or virtual battle?" Although this is the No. 1 Middle School, not the No. 5 Middle School where I am located, it is also Yunhe City. The one who comes is the guest, you come first!

If you are not satisfied with the above, the real mecha battle is also accompanied! ”

Xu Weisong suddenly smiled, "Haha, good!" Since you are so generous, then let's have a realistic mecha battle, cold weapon! Guns and lasers, guns and other weapons are still too dangerous for us, and they don't show ......"

"No need to explain!" Qin Fei's arrogance didn't seem to be revealed, but it was implicit in every action, "No need to explain!" Cold weapons are cold weapons! Reality is reality. How about the urban police humanoid mecha, C-1 level? ”

"Good!" Xu Weisong is also an arrogant genius, although he was interrupted by Qin Fei, he is still arrogant.

Their applications were quickly submitted to the principal of No. 1 Middle School; In fact, the principal of No. 1 Middle School has been watching two bear children fight cross-eyed just now. Seeing that the two of them decided to challenge, they immediately waved their hands, accurately! But the headmaster wasn't very happy!

Although the combat of cold weapons is not as dangerous as the use of high-tech weapons -- it can easily kill people, but it is still dangerous.

Mecha is not only expensive, but also dangerous. However, because of the characteristics of the era of the second evolution, mecha technology has also become popular. Mecha is an extremely important auxiliary tool in the second evolution, a tool for evolution, not just a combat tool.

It can be said that there are two main parts in the second evolution, one is the person himself, and the other is technology. The evolution of man himself, many times, is also the object of exploration in this era. And science and technology, under the guidance of the idea of people-oriented and co-evolution, have chosen - mechanical shell and mecha technology!

Mecha is a crutch and a cradle, and the emergence of science and technology has enabled intelligent life to transcend in wisdom; But our physiology is not able to adapt to the space environment. This requires the use of mechanical shells to make up for our physiological deficiencies. Until one day he becomes an advanced evolutionary and can live freely in space.

The only regret is that intelligent life will always give priority to the application of the best technology to the military.

At that time, when many ordinary people were still discussing the feasibility of mechas, the military situation had changed dramatically, and 3D technologies such as 3D animation and 3D movies had been transformed into mecha control technology, and many data, animation actions, etc. could be directly used for reference; And the maturity of mind sensing technology has also paved the final way for the rise of mecha technology.

At this time, many ordinary people suddenly realized - I, no wonder 3D film and animation technology could get strong support from the state, it turns out that the roots are here!

Computer technology and intelligent technology can make people have more powerful computing power, virtual and network technology can make people have a global vision, and the protection of the mecha itself can make people have an indestructible body. And the mecha as a whole can make people have mythical power: they can carry a variety of weapons of several tons, more than a dozen tons, or even more, and they can freely travel to any corner of the world.

But there is a limit to the fit between the mecha and the human, beyond a certain limit, the person will lose control of the mecha - after all, the power of the mecha and technology is still very strong, and a small negligence may cause the mecha to lose control. This also leads to the division of mecha levels and individual ability levels, and in terms of human body, mental power is the most critical element in controlling mechas.

Mecha have ground, underwater, and more sky and space ranges, and they are not necessarily humanoid; Many flying mechs are in the shape of birds. It's just that as a beginner, most of the mecha are still mainly humanoid.

The C-1 level mecha for urban police is the lowest level of military mecha, which is enough to meet general military applications. Although Qin Fei and Xu Weisong are only D-9 level physical fitness, because the two of them were born in advance, they are enough to control this lowest-level mecha - perfection is definitely not attainable, but the general application is enough!

So the final question is, since the mecha has so many benefits, why does the battle between Qin Fei and Xu Weisong make the principal of the first middle school unhappy? It's simple, money! There are so many benefits of mechas, so the cost of mechas, especially the cost of C-level mechas, you can know what the price is when you think about it with your eyes closed.

Moreover, this Qin Fei is a person from the Fifth Middle School, and now he is using the mecha reserve of the First Middle School, it is no wonder that this principal can be happy!
