Almighty in the city

"15-30! ACE ball!" However, at this moment, the neon referee on duty raised his hand and announced the ball, and Ulliel Borg scored.

Bai Yifan glanced at the neon referee, smiled, and also raised his hand: "I want to challenge Hawkeye."

Tennis's Hawkeye system, the technical name is called "instant playback system", consists of eight to ten high-speed cameras, four computers and a large screen.

When a player expresses dissatisfaction with the referee's decision, he can propose to "challenge the eagle eye".

At this time, four computers will divide the three-dimensional space in the competition field into measurement units calculated in millimeters at the first time.

Then, use the high-speed camera to capture the flight trajectory data of the tennis ball from different angles at the same time, and use the computer to calculate the data to generate a three-dimensional three-dimensional image. Using real-time imaging technology, the tennis movement route and landing point are clearly presented on the large screen. come out.

If the replay of the "Eagle Eye System" shows that the referee made a misjudgment, then the referee's judgment just now is invalid, that is, the player successfully challenged the Eagle Eye and can continue to retain this opportunity to challenge the Eagle Eye.

If the replay shows that the referee did not make a misjudgment, that means the player failed to challenge Hawkeye and directly lost a chance to challenge Hawkeye.

In a game, both players have three opportunities to challenge Hawkeye. If they enter the tiebreaker, they will have another chance to challenge Hawkeye.

Seeing Bai Yifan raising his hand to signal to "challenge Hawkeye", the neon referee on duty sneered in his heart, but on his face he asked formulaically: "Are you sure you want to "challenge Hawkeye"?"

"OK." Bai Yifan nodded.

The Neon chief referee nodded to the Malaysian deputy referee, and the playback function of the "Eagle Eye System" was turned on.

The next moment, on the big screen of the scene, the trajectory of the terrifying serve that had just been played by Ullilberg appeared on the big screen.

The corner of the Neon referee's mouth evoked a sneer.

Frankly speaking, with the ball just now, even he himself is not sure if the ball went into the service court.

The audience widened their eyes as well. This was the first time they saw the "Eagle Eye System" replay in Bai Yifan's game, and the replay was still a 300km/h serve.

On the big screen at the scene, a three-dimensional image of the serve just appeared soon.

The tennis replayed the trajectory at almost thirty times slower speed, and then the computer clearly outlined the trajectory with a red dotted line.

At this moment, everyone can see clearly——

When the ball flew across the net and into the half of the court where Bai Yifan was located, it did not fall into the prescribed serving area, but just pressed one centimeter away from the horizontal line of the serving area.

Obviously, no matter how incredible this serve is, it cannot change the fact that this is an invalid serve.

There was a burst of exclamation in the stands around the scene.

Everyone was shocked by Bai Yifan's terrifying eyesight.

For a serve of 300 kilometers per hour, their eyes can't even catch the afterimage of the ball, but Bai Yifan can accurately see where the ball falls outside the serving area!

One centimeter!

Only a mere centimeter!

This distance, even the head referee on duty could not tell!

All of a sudden, in the sound of exclamation, a mess of discussions began to sound.

Many people are wondering whether Bai Yifan was blinded by this Hawkeye challenge.

Because it is incredible!

Ullilberg snorted coldly, and he also felt that Bai Yifan was purely blinded by this ball.

"He must want to use the opportunity of an'Eagle Eye Challenge' to make a bet. If the bet wins, it can blow my confidence--" Ullielberg thought so and sneered, "However, This kind of trick is too small for me!"

Seeing the Neon referee signaling him to make a second serve, Ulliel Borg didn’t even try tennis this time. He threw the ball directly. His whole body burst out again, accompanied by a roar and a fierce swing. The ball was hit.

On the big screen at the scene, the instantaneous speed of the ball was suddenly displayed——

Two hundred kilometers per hour!

It turned out to be another 300 kilometers per hour!

Although it was a second serve, it was clear that Ulliel Borg didn't mean to ask for stability at all. He still did his best at this time and made another strong serve.

However, in the face of this yellow lightning, Bai Yifan still stood without moving, letting the ball fall to the ground, and then flew past him.

"15-30! ACE ball!" The Neon referee raised his hands again, announcing that Ullil Borg scored the goal.

However, just after his voice fell, Bai Yifan raised his hand again: "I want to challenge Hawkeye."

The Neon referee was taken aback--

Horse, have to challenge the "Eagle Eye System" again?

However, he did not panic at all, nodded, and signaled the deputy referee to start the "Eagle Eye System" playback again.

Anyway, before the tiebreaker, Bai Yifan only had three chances to challenge Hawkeye. Once he made a mistake, he missed one. He also wished that Bai Yifan missed all three challenges ahead of time. Then, his personal "black judge" would be behind him. Time is up.

The playback of the "Eagle Eye System" was called up again, and on the big screen of the scene, a 30 times slow motion playback of the ball just appeared immediately.

A smooth arc trajectory was then marked by the computer with the same red dotted line.

One centimeter!

The landing point of this ball is actually one centimeter away from the line!

This is another invalid serve.

Moreover, Bai Yifan scored the goal directly because of a double serve error.

Ullilberg roared very uncomfortably, but didn't say anything, went straight back to the teeing area, and then hit his fourth serve.

The ball speed is still 300 kilometers per hour, and it is still a yellow lightning laser.

"15-45!" The Neon referee raised his hand again.

And this time, Bai Yifan's hand was almost raised simultaneously with him: "I want to challenge Hawkeye." ,,.
