"Whoosh" rope flicking and the sound of air on the street from far to near, Luan ran and jumped rope through the street. Luan sensed the rhythm of his breathing. Took a deep breath. The air in Qingcheng is very good, maybe it's because of the Yangtze River waterway, maybe it's because of this world.

The world's East Asian steel complex (including China, Japan and South Korea) produces 380 million tons of steel annually. Unlike Lu'an's plane, where China's construction steel accounts for the majority, this world's steel is dominated by marine steel. This means that the structure of the economy is different. All steel mills are located in coastal areas, and raw materials are harvested from all over the world thanks to the dense population of coastal areas.

And the sales are also shipped to all over the world, and now Huaxia is a sea power country, the world's first-class navy to control the strategic points of the oceans. Investing in shipping is the same as investing in railways.

As for the large number of inland areas, they are far less prosperous than Lu'an in 21st-century China. A series of cities along the Yangtze River waterway have the style of big cities, while other areas have the same beautiful natural scenery as the United States in the 21st century. With the exception of Xi'an and Chengdu, few of the major cities in the western interior have a population of more than one million.

The world does not need to communicate the economy of the entire world island through the Belt and Road economic policy, so it is not necessary to have a global navy, and at the same time, it cannot pay attention to the land economy. The construction of vast inland transportation is not something that can be completed in one or two years, but through decades of investment by the will of the state. If it weren't for the fact that the U.S. global navy was too strong, Lu An's plane would not have followed this strategy of investing in the interior for decades.

For a long time, the naval gap between China and the United States in the original world where Lu An's country was located was greater than the maritime gap between Britain and Germany during World War I.

The United States in the 21st century is equivalent to a large Roman Empire, maritime security is related to the country's economic lifeline, which navy has the ability to compete with itself for hegemony in the blue water (the Pacific Ocean, the Indian Ocean, the Atlantic Ocean, the deep blue sea), then it is necessary to fight, "the Pacific Ocean is big enough to accommodate China and the United States" This sentence is a lie that the Chinese are talking nonsense. The national strategy of land power is Go, and on the chessboard of land, Go can live a piece of life if you make an eye, while the national strategy of sea power is chess, and if you lose a move on the chessboard of the ocean, the sun will never set and the sun will never set.

At that time, Rome did not seek common ground with Carthage, and did not hesitate to fight three wars.

World peace in the 21 st century is maintained under a balance of denial and counter-denial on the oceans, and China's fleet can only fight the US fleet in areas covered by medium- and long-range ballistic missiles. In the deep blue region, the United States has an absolute advantage, and the battle between Japan and the United States for hegemony in the Pacific Ocean like World War II cannot be fought at all.

And the East of this world itself maintains a superiority in the fleet of the countries of the world, and the countries of the world cannot challenge the East in terms of the overall volume of industry. This world is far more stable than Luan's.

China as a whole may be better than Lu'an at the same time, but the better here is limited to the coastal area, the golden waterway area of the great rivers. And the inland area is not as prosperous as imagined.

The topic comes back, there is no huge inland industry, so now the air in Qingcheng is very good, there is no haze. It brought great convenience to Lu An's exercise.

Looking at the tall camphors on both sides of the street, Lu An said silently in his heart: "This era is quite good. Twenty minutes later, Lu An slowed down, put the skipping rope into his school bag, and slowly walked towards the school gate, doing a rehearsal as he went.

In some rehearsals, Lu An silently counted, silently counting his heartbeat in his heart. In some rehearsals, Lu An recorded his breathing rate while looking at his watch, and in some rehearsals, Lu An sensed the soreness in his body leg muscles.

In reality, Lu An's various feelings obtained in these rehearsals were projected into his mind, combined with the martial arts magic body information he saw from Yuanyi Space, these feelings were finally sorted out by Lu An into an overall situation. Lu An had a clear understanding of his body, and Lu An could clearly predict where his limits were.

"It seems that the purpose of the hunch needs to be integrated." Lu An muttered this sentence and walked into the school. It was another day of peaceful life, and Lu An was controlling his muscles little by little to exercise more flexibly in addition to class. This is a technique exercise.

Cultivators of the martial arts bloodline meditate for a long time to exercise this technique, but their muscles have true qi energy, and controlling the six hundred and thirty-nine muscles in their body to move as they want is the basic skill of controlling true qi.

For example, everyone can let their fingers move freely, but control the movement of their little finger and leave the other fingers still (pressing with the other hand does not count). It's very difficult to do, because if you move one finger, you will find that the other fingers will unconsciously link. This involves muscular control of the fingers. This is true for the fingers, which are the most flexible parts of the population, and the control of other muscles is even more difficult. (Note: There are people who can control the abnormal and flexible movement of their fingers, thieves can, magicians can do it, and casinos can also make thousands of people.) But almost all of them have been exercised since childhood. ）

No matter how many times he rehearsed, Lu An needs to do it in reality, and in class Lu An seems to sit quietly, and the rhythmic movement of his fingers allows the pen to move flexibly on the tips of his fingers. At this time, when you open your clothes, you can see that the muscle lines under the skin are also moving.

So what looks like the usual day is over. Lu An looks more normal than normal people, and there are many clubs in the school that Lu An does not participate in, including Bajiquan and Tai Chi clubs. These seemingly more combative societies were avoided by Lu An.

Fist and foot training has a role, but Lu An, who came from wartime, scoffs at peacetime martial arts. The greatest use of martial arts in peacetime is not for fighting. Rather, it is used to coordinate the body and make the body healthy and muscular. As for the real hand-to-hand fighting, it was only useful before the First World War.

There are three major theorems in actual combat martial arts that cannot be bypassed.

First: punch not to fight less strong. Adult men have the strongest strength around the age of 20, and the strength of bone toughness is the best. Young people around the age of 20 are most likely to die from fighting. Muay Thai, the most ruthless combat martial art of the 21st century, is the golden age of 20 to 24 years old. Training that borders on masochism. For these professional thugs who have been training since childhood, it is best not to get into physical altercations with them. In peacetime, Chinese people practice martial arts for health, and they do it for not being beaten to death in the fighting ring.

Second: The use of equipment is stronger than bare hands, Lu An has never practiced hand-to-hand combat, but the multi-functional dagger-type bayonet, Lu An has still played it. This skill is definitely better than boxing. One punch doesn't necessarily kill someone. But a dagger-type bayonet with a blood groove is capable of destroying a person with a single slash.

The bayonet design of Luan's first three battles has developed towards higher lethality. There was a bottle of compressed air on the hilt, and a knife was stabbed into it. The high-pressure air rushes directly down the blood tank into the human body, forming a huge cavity. Completely fatal. If a person takes a knife, it is worth five years of hand-to-hand combat for the other party, if you take a gun, if the fighting arena is not a complicated alley, you can say that you have practiced martial arts for more than ten years.

As for the third, the more advanced science and technology become, the more hand-to-hand combat for the purpose of combat effectiveness declines. The development trend of human combat skills is no longer more powerful, but faster, and the world's martial arts are only fast and unbreakable. Draw the gun first, draw the knife first. It's more lethal than a punch with your muscles. (Of course, if there is extra strength such as True Qi in the muscles, then that's another story.) ）

With the above three reasons, Lu An felt that there was no need to go to the so-called gym here to apprentice. In peacetime, there is nothing to learn martial arts under the restrictions of various rules.

In this peaceful world, Lu An usually jumps rope and rackets the ball with a table tennis racket. A nimble and athletic teenager. There's no need to practice competition-like martial arts. In this world, it's better to run with your fists and find the police.

And in Yuan Yi's mission world, Lu An doesn't use his fists, and a close-range shot must be to seriously injure and disable the opponent with a dagger. Fist? That's so tender, that's what girls use to hammer boys' chests in romance dramas. Luan's rehearsal had plenty of time to draw his knife early.

So now Lu An's workout, it can be understood. In the sunset, Lu An ran laps and laps on the track on the circular track on the playground, waving the skipping rope and waving the skipping rope faster and faster, and at the moment when both feet left the ground, both hands could wave the skipping rope twice in a row. In the process, the wrist flicks quickly and almost afterimage. And this kind of movement lasts for a lap and a half, about 600 meters, slows down and jogs for two laps and then starts, not after running for one or two hundred meters and stopping.

Lu An's hard work has attracted the attention of many people on the playground. It seems like too much effort. And Lu An didn't care too much about the eyes of others, his behavior was a little special, but it was not out of line, Lu An concentrated on feeling various parts of his body in the rehearsal, and observed whether his legs and feet would cramp and lose his strength if he exerted further force in the rehearsal. During the rehearsal, Luan observes whether he will be unconscious and dehydrated.

In the corner of the playground, bottles of mineral water and salted boiled water turned into piles of empty bottles, and sweat stained all over the body. In this process, Lu An adjusted his posture through rehearsal to ensure that his gastrointestinal peristalsis was not caused by fluid tremors and convulsions.

Lu An's rehearsal was open for twelve seconds, and Lu An rehearsed at least three times until he was unconscious, so he slowed down in advance. Maintain this state of reaching the limit, always maintaining the limit. When exercise consumes a lot of oxygen, the brain can only focus on rehearsing the projected information, and rarely rehearses other things.

An hour later, Luan's speed was getting slower and harder, and it became more and more difficult to continue the outbreak. After two laps of jogging, allow your heart rate to return to a flat level. Luan dragged his wet body to the school's bathroom and swiped his card to enter. Soak in the pool. Lean your body into the corner of the pool, close your eyes, and your consciousness begins to enter the Yuanyi space.

Work hard to do what ordinary people can do, and hide merit and fame.
