Marvel's Agents of the Spear

How did you see it?

It's a bit stupid to ask yourself this question, but it is a true reflection of Fa Ze's heart.

But if you can see it, you can see it, just like many people don't know that the relationship between muscles and nerves can still control muscle contraction to move hands and feet.

How about giving it a try?

Fa Ze concentrated his mind and controlled the male and female double bombs to rotate and roll out of the backpack as usual.

He vaguely sensed the situation around the male and female double bombs. As the rotation speed of the double bombs increased, his perception became clearer. He even saw himself standing on the tennis court and the ball on his face.

Ok

bump

Unpreparedly, his face was hit by the tennis ball. Fa Ze's body swayed and he fell down.

Jane and Daisy both screamed and ran to Fazer to check on his condition.

To their surprise, Faze's face was only slightly red, which was nothing serious, and his face was not covered in blood as they had imagined.

"How can you hit someone's face with the ball?" Jane asked her boyfriend who was serving the ball unhappily.

Dick smiled nonchalantly, "I just wanted to serve a ball that he could easily catch. Who would have thought that he would react so slowly." Seeing the dissatisfied expression on Jane's face, Dick quickly changed his words, "I'm not a professional player. I can't tell you where to hit."

After checking Faze's condition, he patted his chest and said, "My professional knowledge guarantees that nothing is wrong with him. I used to be beaten often when I was practicing with my coach, and I was beaten more than thirty times a day at most." .It’s nothing if a man gets hit twice with a tennis ball, right, zero”

Having said that, Dick knew exactly how much strength he had used, and Fa Ze's physical fitness was far beyond his imagination.

Ruolin stood aside and asked confusedly, "I understand."

"Yes." Faze nodded and replied with a smile, "I understand."

After patting Dick complainingly, Jane said sheepishly, "Let's not fight now and let Fa Ze rest."

"No, I just discovered the joy of tennis." Faze finally understood Ruolin's purpose of bringing him to play tennis, "Let's continue."

Jane said worriedly, "It's better to rest for a while."

"It's no big deal for a man to be hit twice by a tennis ball." Fazer's eyes turned into crescent moons, "right, Dr. Dick."

Seeing Fa Ze's smile, Dick shuddered inexplicably.

Dick was right. Fa Ze was indeed fine. One reason was that he was in good physical condition, and the other reason was that at the critical moment, Fa Ze controlled the tennis ball to rotate, preventing it from hitting the ball completely.

This was the ultimate purpose of Ruolin letting him play tennis.

Fa Ze finally understood that the Eight Immortals magic weapon had no power, and he was the one who had the power.

By analogy, the Eight Immortals magic weapon is like a big trumpet, which only enhances Fa Ze's ability like amplifying the sound.

The moment of controlling the tennis ball is like adding salt to the cut meat and injecting soul jpg

Faze controls the tennis ball like he controls the male and female double bombs, but obviously does not feel as comfortable as controlling the male and female double bombs.

But it is ultimately controllable.

The racket rotated three times around his wrist and was held tightly again. Faze looked at the ball sent by Dick and was no longer as fussy as before.

As if to avoid suspicion, Dick's ball landed far away from Fazer and bounced out of the court at a wide angle.

Fazer had to move quickly to the tennis ball, swing his arm from bottom to top, and drive the racket to hit the tennis ball.

"Wow!" Daisy exclaimed. The ball just passed through the gap between the net post and the referee's chair where she was sitting, and flew through the air in an elegant arc at a height lower than the net post. Within admission.

"Fifteen to fifteen" was such a beautiful shot that Daisy swayed in her chair and waved her arms excitedly.

Dick was so lucky. Dick was indignant. For a novice like Faze, if he wants to hit such a beautiful forehand side spin, what else can he rely on besides luck? Is he a super power?

Swiss men's professional tennis player Roger Federer has played this ball many times, but he used it in singles. The doubles court is much larger than the singles court, and the difficulty is greatly reduced. Faze can also complete this goal with his super power that he has not yet fully mastered.

The elegant arc of a tennis ball is a nonlinear and complex mechanical phenomenon called the Magnus effect, which was described by German physicist Heinrich Magnus in 1852. However, as early as 1672, Isaac Newton described and correctly deduced the cause of this phenomenon after watching the tennis players of Cambridge College play.

When the rotation angular velocity vector of a rotating object does not coincide with the object's flight velocity vector, a lateral force will be generated in the direction perpendicular to the plane composed of the rotation angular velocity vector and the translation velocity vector. Under the action of this lateral force, the object's flight trajectory will be The phenomenon of deflection is called the Magnus effect.

The most fundamental reason why rotating objects can produce force in the transverse direction is the existence of viscosity, the inherent property of fluid.

When the flow rates of two adjacent flow layers in the fluid are different, or relative motion occurs between the fluid and the object, mutual viscosity and mutual pulling forces will occur on the contact surface of the two flow layers or on the contact surface between the fluid and the object. This characteristic It is the viscosity of the fluid.

The existence of viscosity allows the rotation of the tennis ball to rotate the surrounding fluid, causing the fluid speed on one side to increase and the fluid speed on the other side to decrease.

According to Bernoulli's theorem, an increase in fluid speed will cause a decrease in pressure, and a decrease in fluid speed will cause an increase in pressure, which results in a pressure difference in the transverse direction of the rotating tennis ball and forms a transverse force.

At the same time, since the lateral force is perpendicular to the direction of the tennis ball's movement, this force mainly changes the direction of the flight speed, that is, it forms the centripetal force in the tennis movement, thus causing the change of the tennis ball's flight direction.

When fighting the Iron Overlord, Faze used the Magnus effect to control the rotation of the female bullet, changing its trajectory and drilling into the Iron Overlord.

After the ball was hit just now, Fa Ze sensitively noticed that the rotation stored in the male and female double bombs had become less. It seemed that the Eight Immortals' magic weapon was not only a horn, but also a rechargeable battery.

Dick's third serve, the ball speed was much faster than before, and the position of his arm at the end of his swing was also much higher than before.

Faze quickly approached the spot where the tennis ball landed, and prepared to hit the ball with his racket. However, he saw that after the tennis ball hit the ground, it bounced strangely towards his face.

Dick looked proud. He had just played the best inside topspin serve ever. He had been practicing this kind of serve for a long time, and it was not until today that he finally completed it.

The tennis ball came fiercely, Faze leaned back to avoid it, turned his body, and the racket spiraled upward to hit the tennis ball before it flew higher.

The tennis ball flew towards the opposite side and was about to cross the net.

Suddenly, the wind picked up.
