The sun is getting higher and the temperature in Melbourne is rising rapidly, so if you spend too much time outdoors, you're bound to sweat.

Federer returned to his room after his morning training, took off his sweat-soaked clothes and was about to walk to the bathroom when he heard the voice of the narrator on the television.

"For the twentieth time, I have successfully challenged Hawkeye for twenty times in a row! Zhang Guan has made history again, is he going to bring the record-breaking gesture in track and field to the tennis game? The narrator's words were particularly harsh to Federer.

"Twenty consecutive challenges to Hawkeye success? Is this a joke? Federer stopped in front of the bathroom door and turned and walked over to the TV.

"Zhang Guan's match against Haas, the second set, the score was 3-3, it seemed to be evenly matched, and the first set turned out to be Zhang Guan 6-4 win. Although Haas has a little luck on weekdays, his strength is still very good, and he was broken by Zhang Guan in the first set, and it seems that Zhang Guan should not be underestimated, maybe he will really have a chance to enter the final and meet me. ”

Federer couldn't help but sit down and start watching the match between Zhang Guan and Haas.

"How did you hit this ball so extremely? Sure enough, it was out of bounds...... Does Zhang Guan want to challenge Hawkeye? The challenge was successful! Just pressed a little bit of the sideline, this Haas is really enough to back, this ball has been successfully challenged by Zhang Guan, it seems that this guy has been unlucky in those years, and it hasn't dispersed yet...... Twenty-first Challenge Success? Twenty-one consecutive challenges have been successful! That's impossible! Federer exclaimed, still thinking the commentator was joking, so he immediately walked over to the computer and looked for the report of the match so far.

In the battle report of "Challenge Success, Challenge Success, Challenge Success ......", Zhang Guan's previous successes were all normally expressed, and each of Zhang Guan's successes in the later challenges was marked with bold and black words.

“17、18、19、20！ Counting the time just now, it's really 21 times! Hell yes! Be able to succeed in 21 consecutive attempts. This is definitely not a coincidence, nor is it blind, it is Zhang Guan who really saw the landing point of the ball clearly! Is his eyesight so good that it can be like a computer? Is today April Fool's Day? ”

……

"Zhang Guan and Haas's match ratings hit a new high? Coming back to last year's semi-finals? This is the fourth round! Twenty-second challenge successful? Twenty-two consecutive challenges? OMG! I'm afraid that the entire Melbourne TV audience is now waiting to see Zhang Guan's twenty-three consecutive successful challenges! Tyley, the chairman of the Australian Open committee, hung up the phone and quickly switched the TV in his office to the match.

"Let Zhang Guan compete in the Australian Open, haha, I'm such a genius! This will be the most watched Australian Open ever! I really look forward to Zhang Guan being able to rush to the final and face off against Federer, and he will definitely create a Grand Slam ratings miracle at that time! "Telly is looking forward to a better future at the same time. On the screen, Zhang Guan has already begun the twenty-third challenge.

"Twenty-third! It must be a success! Terry began to pray silently in his heart.

……

CCTV, the sports channel studio.

"Sister Na lost 1-2 to No. 6 seed Hingis, and this time our golden flower in the women's singles event was completely wiped out. You can let some people in the station come back first, leave a few people, and report on the doubles match. The director sighed, and then suddenly remembered Zhang Guan.

"I don't know what happened to Zhang Guan, his opponent in the fourth round was the German golden boy Haas, and what is the way he is playing now. Does Zhang Guan have any hope of advancing to the quarterfinals? The director opened his mouth and said to one of his subordinates: "Cut the signal from Vodafone Stadium and I'll take a look." ”

After a while, the broadcast signal of Vodafone Stadium cut to the display screen in front of the director, who put on his headphones and looked at the score on the screen.

"Zhang Guan is ahead! The score of this set has reached 5-3. If Zhang Guan wins one more game, he can win this set. The first set was also a victory for Zhang Guan, so Zhang Guan was very close to 2-0. The director thought silently.

"Challenge! Challenge! Challenge! Challenge! The loud shouts of the audience rang out from the headphones.

"Challenge? Is it a challenge to Hawkeye? Isn't it just a challenge Hawkeye, why is the atmosphere so tense? It feels like a penalty shootout. The director was a little puzzled, and at this time, Zhang Guan on the screen had already successfully challenged.

The scene resounded with even more violent cheers. The audience was boiling, and the narrator's tone was very excited.

"Twenty-fourth consecutive challenge to Hawkeye? OMG! The director stayed on the spot, and the next moment, he pulled off the headphones violently, and his expression was even more distorted.

"Why don't you let me broadcast this kind of competition! Today is supposed to be the weekend, and if this can be broadcast, the ratings will definitely skyrocket! No, I have to go to the director, even if it's a record, I have to broadcast this game! ”

……

Even on the weekend, Director Liu of the Network Management Center did not rest at home today, he came to his office. One is because he has the conditions to watch the Australian Open, and the other is because he is waiting for a very important call.

"It's 2-0! Zhang Guan has won again! If you win the next set, you will enter the quarterfinals of the Australian Open! Twenty-five consecutive challenges to Eagle Eye have been successful, and I think this Eagle Eye system should be renamed Zhang Guanyan System! Director Liu said to himself.

At this moment, Director Liu's phone rang, and he immediately picked it up.

"I'm Xiao Liu! Honorary chairman, is he willing to help us speak? Say hello to the people at the Radio and Television Bureau next Monday! Great, with his old man to speak, he will definitely be able to lift the ban on Zhang Guan! Okay, don't worry, I'm ready to do that, and once I get the notice, I promise to bring up the publicity! ”

Director Liu put down the phone and let out a long breath: "It's great that the old man is willing to speak this time!" I will wait until tomorrow, when the people of the whole country know that Zhang Guan has entered the quarterfinals of the Australian Open, they will be surprised! ”

……

In the hotel's room, Coach Joyce was also watching the game live.

"Not necessarily, maybe I can 100% succeed in the challenge!" Zhang Guan's words were constantly circling in Coach Joyce's mind at this time.

"It's not a joke to be 100% successful, Zhang Guan is really able to do it! Is this guy an alien? It is necessary to accurately determine the landing point of the tennis ball in the game, but it is not enough to rely on good eyesight, and the image is presented on the retina. Through the nerves and then transmitted to the brain, the brain then makes analysis and judgment, so it is necessary to have excellent brain power. It takes not just the best eyesight, but the strongest brain! It seems that our king of track and field is not only fast enough, but also has a much faster brain than others! ”

……

The fourth game of the third set between the two sides. At this time, Haas once again used up the opportunity to challenge.

"Whoosh!" The tennis ball flew over the net, and Haas ran hard but still didn't receive the ball, and then the referee awarded Zhang Guan a direct score.

"This ball is out of bounds! Is the referee blind! If there is still a chance to challenge, I will definitely use the facts to tell these judges who is right! Haas shook his head in exasperation. He would love to protest to the referee and express his displeasure, but he also knew that that might only have the opposite effect.

"Oops, the last thing I want to see seems to have happened, Zhang Guan's successive successful challenges also put a lot of pressure on the referee, some balls, between out of bounds and in bounds. When the line referee can't make a clear judgment, they will directly make a judgment that is biased in favor of Zhang Guan, and they are also worried that Zhang Guan's challenge will be successful, causing them to misjudge! Haas could feel it. Now it's not just the score behind, but even the overall situation is getting more and more unfavorable for you.

Every successful challenge for a player is a misjudgment for the referee, as a referee. Of course, I don't want to make many miscalculations. Now Zhang Guan's more than 20 consecutive challenges have been successful, which has invisibly put huge pressure on the referee, and the audience at the scene also looks like they are afraid that the world will not be chaotic. Every time Zhang Guan challenged, he all followed suit, which made the referee's judgment more cautious.

Zhang Guan's ball speed is originally the fast one, especially the serve, the ball with a speed of more than 200 kilometers per hour, in the process of landing and bouncing, the contact with the ground is only for a moment, so many times, the line referee can not be 100% accurate judgment, and some ball referees even feel that the possibility of going out of bounds is greater, but in the worry of their own misjudgment, the referee will often make some judgments in favor of Zhang Guan.

At this time, Haas felt very tired, although the match had only come to the third set and there were not too many rounds, Haas still felt very tired. This tiredness is not caused by physical fatigue, but by psychological stress.

The audience is looking forward to the success of Zhang Guan's next challenge, and today's Vodafone Stadium has become Zhang Guan's home stadium; Because the referee was worried about the misjudgment he had made, he was more biased towards Zhang Guan in the judgment; What's more, Zhang Guan can succeed in every challenge!

Later, every time Zhang Guan said that he wanted to challenge, Haas had a feeling of horror, whether it was the referee's decision to score directly against Zhang Guan, or the decision to restart the game, it made Haas feel a sense of frustration that his efforts were wasted.

Haas was hoping to play a few beautiful match-holding balls, show his indomitable spirit, and boost morale, but Zhang Guan did not give Haas this opportunity, Zhang Guan's return point selection is all very extreme, a posture of unsuccessful and benevolent, basically three or five shots to end a goal.

"I can be knocked down, but I must not be knocked down!" Haas didn't give up, even when he was down 2-0 on aggregate, and even when he was broken by Zhang Guan in the third set of the coaches, he still held on.

In the end, the score of 6-4 in the third set also fully proved Haas's intention to persevere to the end, if it was not unfortunate for Zhang Guan to get a break in the first game, maybe Haas had the ability to drag the game into a tie-break.

"It's over! Congratulations to Zhang Guan for his victory over Haas and his successful promotion to the quarterfinals! At the same time, we also congratulate Zhang Guan for making history, reaching the quarterfinals of a Grand Slam for his first professional tennis match. The commentator paused, then said: "Maybe before the game, there was a lot of speculation that Zhang Guan could beat Haas to reach the quarterfinals, but I think everyone thinks that this is a very tough game, and the two sides may play for a long time." But no one would have imagined that Zhang Guan would win the game in this special way, and the challenge of the whole game was successful thirty-two times, and it was thirty-two consecutive challenges! I really didn't expect Zhang Guan to have such accurate judgment, and I think that in the future competition, no matter which player meets Zhang Guan, he will feel a little troublesome. At least in terms of challenging Hawkeye, he can't win against Zhang Guan. ”

……

The success of the 32 consecutive challenges has brought not only widespread attention, but also a large number of doubts. Anything that makes people feel unexpected will be questioned, not to mention that Zhang Guan has successfully challenged Hawkeye for thirty-two consecutive times, which seems to everyone to be completely fantastical.

Some say that the Australian Open's Hawkeye system has loopholes, some say that there is a problem with the operation of the Hawkeye system, and some conspiracy theorists say that the Australian Open host committee "deliberately helped" Zhang Guan to advance in order to increase ratings and media attention.

In the face of doubts, the Australian Open's main committee first stood up to clarify.

"There are absolutely no problems with our operation on the Eagle Eye system." The spokesperson continued: "The Eagle Eye system does require an operator to operate, but the operator only needs to press a few buttons to operate. The entire 3D simulation screen is still generated by the computer system, and it is impossible for the operator to change the 3D simulation screen generated by the computer system. And we also checked every challenge of Zhang Guan after the game, and the result was completely consistent with the game. ”

"The computer programs of the Eagle Eye system are all designed, and we just bought this system, but did not buy the patent rights of this system, so we don't have the program key and related code, and we can't modify the established program, and the so-called 'deliberately helping Zhang Guan advance' is obviously impossible."

"I don't want to answer the question of whether there are vulnerabilities in the Eagle Eye system. Because we are not the ones who invented this system. The spokesman looked at the manuscript in his hand. He continued: "Our Eagle Eye system is provided by Eagle Eye System Innovations, not only us, but also by Eagle Eye Systems Innovations, which are used in other Grand Slam tournaments and some high-level tennis tournaments. Eagle Eye Systems Innovation, Inc. owns the patent rights to use this system. It is also a qualified company designated by the International Tennis Federation. ”

The spokesperson for the Australian Open successfully dumped the "pot" on the supplier of the Eagle Eye system, Eagle Eye System Innovation Ltd. in the United Kingdom.

However, just over an hour later, a statement appeared on the official website of Eagle Eye System Innovation Co., Ltd. The general content of the statement is that the company's Eagle Eye system is free of vulnerabilities, and there are several attachments behind the statement. Including the patent certificate of the Eagle Eye system, the scientific and technological innovation award certificate issued by the Royal Palace Examination Association of the United Kingdom, the outstanding scientific and technological contribution award certificate of the American Emmy Award, the qualification certificate issued by the International Tennis Federation, and the audit and test report of most of the tennis celebrities responsible for reviewing this technology. Obviously, Eagle Eye System Innovation Ltd. is desperate to prove that there is nothing wrong with the Eagle Eye system.

……

In the conference room of Eagle Eye System Innovation Co., Ltd., General Manager Allen put down the phone.

"I just spoke on the phone with Professor Paul Hawkins, the inventor of the Hawkeye System. Professor Hawkins said that our Hawkeye system is a high-speed camera that captures the trajectory of the ball, including the trajectory before and after landing, and then calculates the landing point of the ball through a formula, and then generates a three-dimensional image. Actually, the formula for calculating the landing point of the ball is not complicated, and I think you have already learned about the calculation of parabolas in middle school. ”

Alan took a sip of coffee and continued: "So according to this theory, if you are a mathematician or a physicist, even if you don't need to look at it, you can calculate the landing point of a tennis ball just by relying on a few parabolic numbers. Maybe Zhang Guan is using this method? ”

"With calculations? I don't believe it! Does he still have to bring a calculator and measuring tools to the court? Someone next to him immediately shook his head and said.

"I don't believe it either!" Alan sighed: "But the movie "Rain Man", you should know! Like Raymond in "Rain Man", he can quickly count the toothpicks that have fallen on the ground, and the speed of mental arithmetic is not inferior to that of a calculator......"

"But that's just a movie!" The man retorted.

"But "Rain Man" also has a prototype!"

"But the public and the media will certainly not accept this explanation!"

Alan waved his hand to signal everyone to be quiet, and at the same time said: "The public and the media will not accept such a ridiculous explanation, so we need Zhang Guan himself to prove that he has this ability to judge the landing point of a tennis ball!" ”

"Let Zhang Guan prove it himself? Do you want him to fight Haas again? ”

"Of course, we don't have to go through that much trouble, we can do a public test in Melbourne and invite journalists and officials from the International Tennis Federation to participate. Find a ball machine, serve the ball to the sideline, and let Zhang Guan judge whether the ball is out of bounds in front of everyone. Alan spoke.

"What if Zhang Guan doesn't want to come?"

"Pay for him! Contact Zhang Guan's agent immediately and ask him how much he needs to pay for his appearance! Alan went on to say, "Ladies and gentlemen, the Eagle Eye system is the only product of our company, so no matter what, we have to prove to the world that our products are absolutely the safest and most reliable!"
