On the train back to Amsterdam from Arnhem, the Ajax youth team players were laughing and joking. The massacre had made them unusually excited, and they were unscrupulously making fun of the Vitesse youth team's cowardly final performance.
Qin Xiong sat by the window, resting his chin on his hand. He looked at the scenery outside the train that was passing by quickly, but he was not too excited.
Outsiders could not understand his ambition. Perhaps many people thought that it was normal for an 18-year-old like him to progress step by step in the youth team.
However, he wanted to reach the top in one step!
In particular, he did not feel challenged at all in the youth team.
Perhaps, if he was switched to the Vitesse youth team to play against the Ajax youth team, it might be a little more challenging.
Through this game, his teammates on the field had already acknowledged him. Wiltonghen sat beside him, while Buhari and Babel sat opposite him. The three of them would take the initiative to chat with Qin Xiong from time to time, discussing interesting things in the game, such as the moment when the opponent looked away, or the dazed or pained expression after conceding another goal.
As a winner, it might not be ethical to use the losers as a topic of conversation for fun, but it was a reality that existed in every corner of the world.
It could be said that if there were no losers, how could there be a winner?
A winner would use the pain of a loser to set off their own success.
Qin Xiong was not interested in discussing these things, and his teammates did not mind. They only thought that Qin Xiong was an introverted person. On the field and off the field, Qin Xiong was a completely different person. On the field, he was extremely active and everywhere. Off the field, he would quietly stay in a corner. If no one took the initiative to disturb him, it was as if he did not exist.
Most of his teammates accepted him and recognized him from the bottom of their hearts. After all, everyone gathered in Ajax and used football as a bridge. Football strength was the foundation of this collective existence.
However, there were also people who were dissatisfied and were even more hostile towards Qin Xiong. Morpheus and Ilmas had been sitting on the bench for 90 minutes and had witnessed Qin Xiong's performance as the ruler of the field. Every goal that Qin Xiong scored was like a loud bang that struck their hearts, causing their sense of crisis to increase dramatically!
Back in Amsterdam, Qin Xiong said goodbye to his teammates and returned to his apartment on Wardle Street alone.
In front of the apartment, Freddy was waiting for Qin Xiong outside Dekoze's restaurant. When Qin Xiong came back, he immediately pulled out the chair beside him and waved to the waiter in the restaurant to signal that dinner was ready. He then asked Qin Xiong how the competition went.
Qin Xiong casually told Freddy the result.
"Hahaha, good job. Did Brinder praise you? Did he say that you would be promoted to the higher echelon? "
Qin Xiong shook his head and waited for the waiter to serve dinner. He ate quietly.
After dinner, Qin Xiong returned to the apartment and rested for a while before beginning his self-study in the evening.
.....
The next day, Qin Xiong went to train as usual. Because there was a game yesterday, today's training task was not heavy and focused on recovery and relaxation. The afternoon training also ended early because the reserve team had a game. Later, the First Team would also welcome the Eredivisie at home. The club's attention was naturally placed on the First Team.
His teammates left one after another. Some went to watch the reserve team's game, while those with better financial conditions went to Ajax's home ground to watch the First Team's game. They looked forward to the day when they could represent the team in the spectacular Amsterdam Athletic Stadium.
Qin Xiong stayed alone on the training ground and communicated with the stadium administrator. He asked for a bag of footballs and walked to a position 30 meters in front of the goal. He placed more than 20 footballs in a fan-shaped position and then carried out free kick training by facing the different angles of the goal.
Observation, run-up, shooting. The cycle repeated.
Qin Xiong pursued every shot from a tricky angle and the football would definitely be kicked in an obvious arc.
Perhaps it was because of his own thinking, except for short and medium range shots, Qin Xiong's long-distance free kicks and long shots were mainly curveballs.
He did not like the football to move in a straight line. He was fond of the football's unpredictable parabola trajectory in the sky.
Therefore, when he practiced free kicks and long shots from a young age, he would use the instep of his inner foot to create a huge friction force when he touched the football, causing the football to spin rapidly after it rose into the air and form an obvious arc.
As he grew older, his strength increased. When he took long shots and long-distance free kicks, his body would tilt significantly at the moment he supported his body. This was to ensure his strength and balance. Although it was not as exaggerated as Beckham's Beckham's Bayesian Arc, where his body tilted as if he was about to fall, Qin Xiong also increased the speed of the ball on the basis of pursuing the arc.
Recently, something had happened that confused him.
If he used all his strength to shoot a curveball, the first half of the football's flight was normal, going out in an outer arc and then spinning inward, but the second half had a problem.
The flight trajectory of the football sometimes did not end in a complete arc. Instead, there would be irregularities and an unpredictable trajectory that was erratic.
This made Qin Xiong feel that the football was out of his control.
Bang!
Qin Xiong shot another free kick and then witnessed the flight trajectory of the football. After the initial arc rotation, when it reached the apex and fell, the arc trajectory of the football still existed, but it already had a tendency to fly straight!
It formed a strange arc, consisting of a large arc in the front half and a small arc in the back half.
Bang!
The football hit the crossbar of the goal and bounced off.
Qin Xiong bowed his head and pondered over the reason for this phenomenon. This was not a special case or an accident, but a situation with a high probability when he used all his strength to shoot.
He tried another kick and reduced his strength. Then he saw the football complete its flight trajectory with the large arc he was familiar with in the past. There was no irregular change, and it steadily circled around the outside before falling into the goal.
He put his hands on his hips and pondered.
Obviously, he found part of the reason for the uncontrollable phenomenon. First, it was related to the strength of his kicking.
"What are you worried about?"
Someone suddenly spoke behind him.
Qin Xiong turned his head and saw the famous Louis Van Gaal.
Qin Xiong politely greeted the other party, "Hello, sir."
Louis Van Gaal asked again, "What are you worried about?"
Qin Xiong told the other party about his confusion and proved his story through three consecutive free kicks. Although one of the kicks did not show the irregular trajectory, the other two balls showed irregular trajectories when they flew and fell.
Louis Van Gaal's expression was the same as usual, but he admired Qin Xiong even more in his heart.
First of all, the other party was here to practice. This was a professional attitude. No manager would dislike such a player.
Secondly, he saw Qin Xiong kick almost 20 free kicks. With Qin Xiong's level of free kicks, his eyes lit up.
As for Qin Xiong's confusion, he could really answer it.
He walked over and picked up a football and said, "The scientific knowledge involved in the flight of a football in the air is mainly hydrodynamics. Simply put, the flight trajectory of a football is not only controlled by you, but also by the air resistance in front of the ball, the air suction behind the ball, the friction of the surrounding air on the football, the rotational force of the air vortex on the football, and so on. First of all, you have to understand that when the football is kicked out, that is, the moment after your foot kicks the ball, the football's speed is at its fastest. Within a certain speed, the flight trajectory of a football is familiar to us, such as a curved ball or a straight ball. The football will not change too much, or even if there is a change in trajectory, our naked eye will ignore the change in subtle deviation. However, when the ball's speed reaches a high enough speed, or breaks through a critical point, the deviation of the football's trajectory under the influence of various air resistance, friction, rotational force, and suction forces will produce a qualitative change, which can be clearly observed by our naked eye. So, congratulations, the level of your free kicks has crossed the threshold of an elevator ball. If you want to often kick such unpredictable free kicks in the future, my suggestion is to reduce the pursuit of curves and focus more on the explosion of power and the control of footwork, and try to keep the football as still as possible. "
Qin Xiong frowned slightly. He did not like the football to remain still while flying. That kind of trajectory was only a straight line, lacking variation or a sense of beautiful lines.
But he decided to listen to Louis Van Gaal's suggestion and give it a try.
He ran up, supported his body, and made sure that the football was in a non-rotating state when he kicked it.
Bang!
The football shot out like a cannonball.
The speed of the ball was so fast that it passed in the blink of an eye!
Qin Xiong and Louis Van Gaal watched the trajectory of the football's flight together. The football, which was flying upward, suddenly produced an erratic trajectory when it fell. If it was observed at 10 times slower speed, it produced a snake-like irregular trajectory in the short distance in front of the goal!
Qin Xiong opened his mouth slightly and felt a little surprised.
Perhaps, he did not like straight lines when he was a child because he did not have enough strength. No matter how he kicked or how much strength he used, the football was generally in a straight line.
But now, his strength was enough to make the football's flight process act on the fluid dynamics to produce an irregular trajectory!
Van Gaal chuckled. "It's precisely because of the static state of the sphere that the movement of the ball is only affected by the pressure difference on the surface of the streamlined surface and gravity, and not by the air pressure generated by the rotation of the sphere. That's why it's able to create an erratic trajectory. Young man, you're great."
