On the way back to the maid shop, Xiao Fei has been watching the hot search of Weibo topics.

"'Disheveled eye-catching girl', Susu, you are on the hot list of hours!" He half-jokingly said to Su Su, who was sullen next to him.

"Obviously, I appeared in such a handsome way." Su Su complained, "As a result, everyone only cares about my clothes, what can I do, my clothes are not armor, they will rot in case of explosion!" Don't they think it's Superman's underwear on the outside, no matter how hard they fight, it won't rot! ”

"Superman is wearing tights, and Billy Herrington is wearing only panties." Amber complained matter-of-factly.

"Speaking of which," Xiao Fei looked like Su Su was about to explode, and hurriedly changed the topic, "Where is the eldest sister's head?" ”

"Let's do an on-site investigation, after all, we need to identify the prosthetics used by the terrorists we killed. The eldest sister is an expert in this area, and she has seen prosthetics in almost every country. ”

"Is it because of the proxy war?"

Xiao Fei muttered quietly.

In the past, the so-called proxy war was only a term in academic circles, but in the last two decades, it has become an umbrella term for a series of wars that have taken place in the South Asian subcontinent, Africa and Latin America, and has changed from an academic concept to a specific term that is widely recognized in society.

This series of wars has the same characteristics: both the old world hegemon and the new world hegemon are involved, not only providing weapons, financial and technical support to the warring parties, but also directly sending troops to the war in the form of mercenaries. At first, everyone used the "joint war on terror" as a fig leaf, and later the mercenaries on both sides – formally called civilian security manpower contractors – simply tore their faces and attacked each other.

Therefore, it is also called "a rehearsal of the Third World War" by pessimists.

China also sent a large number of troops under the banner of mercenaries to participate in the war, and the opponent was, of course, "a certain country". The great progress in prosthetic technology is also due to the large number of wounded soldiers on the battlefield. The use of prosthetics to allow disabled soldiers to regain normal human beings - no, to gain physical abilities beyond normal human beings, and then return to the battlefield with combat experience greatly reduces the manpower consumption of proxy warfare.

Then in order to produce weapons and equipment with greater efficiency, prosthetics began to be used in the civilian field.

With the resilience of a human, the power and precision of a machine, there is no more perfect workforce than this - the only flaw is that the prosthetic person will still be tired and will be paid.

In this way, the combination of prosthetics and 3D printing gave birth to a huge change in what is collectively known as the Fourth Industrial Revolution, and the source of this change is proxy wars, a series of unjust battles generated by the contradiction between the hegemony of the old and new worlds.

The Fourth Industrial Revolution, in turn, contributed to the change of hegemony between the old and new worlds.

Now, even the most stupid people can see in whose hands the scepter of the world hegemon will be held in the next hundred years.

However, there are still two decades left before the end of the century, and the old hegemon is still brewing a final counterattack.

The above is what Xiao Fei learned in the world situation analysis class.

"The eldest sister used to be a mercenary...... Xiao Fei leaned back in his chair, sighed and turned his head to look out of the cabin, and then he exclaimed, "What the hell is that!" ”

"Fans, every time the maid team participates in an action that arouses widespread concern in the society, the maid shop will be crowded by fans." Su Su shrugged his shoulders at Xiao Fei, "I can receive a lot of condolences from fans." ”
