NBA Wolverine

Chapter 439 Breaking World Records
The referee raised his head, looked at Diack and said in a trembling voice: "9, 9.35 meters."

"Oh!"

Countless reporters around exclaimed, sweeping through the long jump area like a whirlwind.

"9.35 meters?" Li Hong was shocked.

"what?"

Diak's heart was pounding, and he shouted, "Measure it again, and measure it carefully."

"OK."

The referee quickly measured again.

"Li Hong, Li Hong?" Yang Jian couldn't help but shout in the CCTV live broadcast room.

"I'm Li Hong. This is the second jump of the Mid-Autumn Festival. The first measurement is..."

At this point, Li Hong emphasized her tone and said in a very excited tone: "9.35 meters. We are confirming it now."

"what?"

Yang Jian and the other two commentators were stunned.

"9.35 meters?"

The same is true for countless Chinese people in front of their televisions.

At this time, the referee confirmed that it was correct, straightened up and said loudly: "9.35 meters."

"Oh!"

The exclamations were heard again.

Li Hong said excitedly in front of the camera: "Dear audience, it has been confirmed that under a wind speed of -0.1 meters per second, Zhongqiu's second jump result is 9.35 meters."

"He broke his own world record of 9.24m, the world championship record, and broke the Olympic record of 8.90m."

"9.59 seconds was the beginning of the miracle of the Beijing Olympics. It was a legend on the -meter track."

"Now, he has created his second myth, his second miracle, 9.35 meters. Zhongqiu has created a new Olympic record and world record for men's long jump."

At this time, all the electronic screens in the Bird's Nest displayed He Zhongqiu's score of 9.35 meters, and the scene was boiling.

"Oh oh oh……"

The rolling cheers were like the Qiantang River tide on August 15th, endless.

In front of the TV, more than one billion Chinese people were cheering excitedly.

He Zhongqiu has been surrounded by countless media. The long jump area is somewhat out of control and the competition is impossible. A large number of security personnel quickly control the order at the scene and protect He Zhongqiu's departure.

"Director Luo, I won't jump the third time." Before leaving, he shouted to Luo Chaoyi.

"well."

Luo Chaoyi, who was so excited that he couldn't speak, nodded quickly.

"Oh my God, 9.35 meters, this is amazing for Mid-Autumn Festival!" Liu Xiang said to his girlfriend Tong Xiaoya after a round of warm-up.

"The boss is so powerful!" Tong Xiaoya said with admiration.

Liu Xiang exclaimed: "8.95 meters made long jumpers all over the world look up to him. He jumped 8.99 meters, then 9.16 meters, and then 9.24 meters, which was simply despairing.

Today he jumped 9.35 meters again. I bet that in a hundred years, no one except himself will be able to break his 9.35 meters. "

At this point, he said unconvincedly: "No, I can't let him take the limelight alone. I have to work hard and break a record for him to see."

"come on!"

Tong Xiaoya smiled and raised her fist.

Next, Liu Xiang began the second round of warm-up.

At this time, He Zhongqiu came over and shouted, "Liu Xiang, in this Olympics, let's not talk about 12.88 seconds, try to break your own 12.91 seconds."

"Just watch me." Liu Xiang patted his chest and replied loudly.

"Boss." Tong Xiaoya waved her hand and shouted.

"Hello."

He Zhongqiu and Tong Xiaoya had met several times these days, but they were not very familiar with each other. However, as a friend of Liu Xiang, he asked:

"How did the talk with Liu Xiang go?"

Tong Xiaoya smiled and said, "It's good. Athletes don't have as many worries as those in the entertainment industry."

"That's good. It feels good. Let's get married earlier. We are already grown up." He Zhongqiu said this and entered the passage.

Tong Xiaoya opened her mouth wide. Is she not a child anymore?
No, boss, I'm just starting out, I'm only 24 years old!

At 9 o'clock, the second round of the men's 110-meter hurdles began, and Liu Xiang advanced to the semifinals with the second place in the group.

He Zhongqiu also appeared on the field again, and the men's high jump final was about to begin.

Luo Chaoyi, Feng Shuyong, Sun Haiping, the three directors of the Track and Field Center were all present, as well as Liu Xiang, Dayao, and a large group of people showed up to show their support.

A large group of swimming and diving champions had just finished their competitions and ran over from the Water Cube next door. There were more than a dozen Olympic champions, big and small.

Guo and Huo also came. Huo Gang even took a photo with He Zhongqiu and said expectantly, "Zhongqiu, you can't miss the trip to Hong Kong after the Olympics. You should have only been to Hong Kong once, and now everyone in Hong Kong is looking forward to seeing you."

"Ha ha!"

He Zhongqiu smiled and said, "The big gold medal your family gave me is great, so I'll take it myself this time."

"It's a word."

The person who said this was not Huo Gang, but his father, who had just come from the Water Cube.

The Huo family father and son also came during the 4-meter race the day before yesterday. They knew He Zhongqiu during the Athens Olympics four years ago.

"It's a word."

He Zhongqiu shook hands with Lao Huo and took a photo together.

At this time, the high jump final began, and He Zhongqiu was in fifth place.

The original rule was that athletes with a preliminary score of 2.32 meters and the top 12 scores were allowed to participate in the finals.

But in fact, in the final, only He Zhongqiu jumped 2.35 meters, which was above the grid line. The others were around 2.3 meters, and the Athens men's high jump champion Holm only jumped 2.29 meters.

Therefore, the rules for participating in the finals were changed. Any athlete whose preliminary score reaches 2.25 meters can participate in the finals.

There are three strongest opponents in the final, Andrei Shirnov and Rebakov from Russia, and Jermaine Mason from Britain.

Li Hong introduced to the camera: "Shirnov's best result is 2.37 meters, and he won the European Championship in 06."

"Mason is a Jamaican who became a British citizen. His best time is 2.35 meters. His good friend, -meter sprinter and silver medalist Bolt, was also there to show his support. Look, there he is."

"The famous high jumper Rebakov won the runner-up in the high jump at last year's World Championships in Osaka with a score of 2.35 meters."

At this point, she added: "Comparing the advantages and disadvantages of these three people and Zhongqiu, Zhongqiu is actually at an absolute disadvantage in terms of weight."

"For example, Rebakov is 198 centimeters tall, but he weighs only 83 kilograms, while Chul-au is 211 centimeters tall and his weight has always been 120 kilograms."

"There is a 37kg weight difference between the two, which is a huge difference. In the high jump, or even in the long jump, a one-kg weight difference is a huge burden."

"Now we look back and see how amazing Zhongqiu's Olympic record of 9.24 meters in the long jump was."

"He needs to bear more than 30 kilograms of weight than other athletes, and he can also jump farther and fly higher than others."

"With his talent, we can imagine that if his weight is kept at around 100 kilograms, I think he can really fly, haha!"

At this time, He Zhongqiu had already applied to the chief referee for his take-off height, 2.35 meters.

"Wolverine, are you sure?"

This height made the chief referee ask seriously.

"Sure." he said.

Luo Chaoyi and others nearby did not say anything. Instead, they hoped that He Zhongqiu could lower his jumping height, for example, starting from the Olympic A standard of 2.30 for more stability.

"OK."

The chief referee nodded and noted He Zhongqiu's jumping height.

At this time, the first athlete started his first jump. He asked for 2.20 meters and passed.

Each athlete has three attempts at each height, raising the bar by at least two centimeters each time.

He Zhongqiu stood at the outside, jogging occasionally to keep warm. His first jump height was 235 centimeters, and it would take a long time for him to jump again.

After 80 minutes, the pole finally rose to 2.32 meters. At this time, there were only 4 people left, and the others were eliminated.

Even the defending champion Holm was eliminated due to poor condition.

Li Hong said to the camera: "Dear audience, now there are only Shilnov, Rebakov, Mason, and Zhongqiu left."

"Zhongqiu hasn't jumped yet, and he hasn't reached the first height he wants, 2.35 meters."

At this time, Rebakov started jumping, 2.32 meters, but his first jump failed and he fell off the bar.

Mason jumped next, his hip brushing the pole, which jumped but did not fall, and passed.

Then came Hillnov, who was in the best condition. He had passed the previous three heights in one try, and he also passed the first jump smoothly this time.

Then it was Rebakov's second attempt at 2.32 meters, and this time he successfully cleared the bar.

"2.34 meters."

Mason glanced at He Zhongqiu behind him and asked for the height.

"2.34 meters, one centimeter away from the 2.35 meters of the Mid-Autumn Festival."

As He Zhongqiu's first jump approached, Li Hong felt a little nervous.

Mason ran up and took off on one foot with a back-flip. The moment he flew over the bar, his hips brushed against it and he fell.

"Shet!"

He bounced off the foam pad and cursed in frustration.

Next up was Shilnov, who made his first successful jump.

Then Rybakov, failed.

The two started their second attempt.

This time, Mason passed and Rebakov didn't.

But on the third attempt, Rebakov passed.

After the three of them passed, all eyes turned to He Zhongqiu, and it was his turn to jump for the first time.

"Finally it's my turn."

He Zhongqiu had been active nearby for more than an hour. It was now 11.45:, almost midnight, and he had already had his midnight snack.

The three directors of the Track and Field Center were always there, as well as more than a dozen Olympic champions, the Huo father and son, Liu Xiang and others.

The referee raised the horizontal bar to 2.35 meters, checked it, and signaled He Zhongqiu that he could try jumping.

"It's Mid-Autumn Festival now, I hope everything goes well." said Li Hong.

"Clap clap clap..."

The Bird's Nest immediately erupted in huge applause and cheers.

Late at night, few of the 90,000 or so spectators left. They all came to celebrate the Mid-Autumn Festival. Although they were very tired, their enthusiasm remained unabated.

He Zhongqiu's running distance is 30 meters.

The running distance for high jump should be no less than 15 meters, and should generally reach 20 meters.

The flop high jump is different from the long jump. The speed is too fast to be controlled, so the running distance cannot be too far.

"here we go."

When He Zhongqiu started to run, Li Hong said expectantly.

In a straight run-up, He Zhongqiu landed on the sole of his foot, took even steps, and continued to accelerate, then entered the arc run-up stage.

At the moment of jumping, He Zhongqiu bounced up suddenly and swung his arms vigorously.

The purpose of jumping is to instantly convert horizontal speed into vertical upward movement.

He Zhongqiu soared into the air and did a backflip over the bar like an eagle flying backwards. His back slid over the bar lightly and his calves swung upwards.

"Oh……"

At midnight, the Bird's Nest immediately erupted into huge cheers.

"it is good!"

Luo Chaoyi and others cheered.

Amid cheers, He Zhongqiu landed on the sponge mat, and the crossbar remained motionless.

He raised his fist towards the stands, and the cheers in the Bird's Nest suddenly rose to a higher level.

"Pretty!"

Li Hong cheered and said excitedly: "Zhongqiu succeeded in the first jump, 2.35 meters, and currently ranks first. Now the pressure is on the other three people."

"call!"

Mason felt the strong pressure and then he jumped.

2.36 meters, this is the height he wanted.

"Mason asked for 2.36 meters, which is two centimeters higher than 2.34 meters."

In the CCTV live broadcast room, Yang Jian introduced: "He must be under a lot of pressure. He has already jumped from 2.2 meters many times. He must have consumed a lot of physical energy. He may not succeed next time."

Han Qiaoshen said: "His best results are 2.35 meters and 2.36 meters. He has never jumped beyond that. He is challenging his own limits."

Sun Zhenping said: "The chance of success is not high."

Sure enough, Mason's first jump failed and he knocked the pole off the ground.

Next, Rebakov tried 2.36 meters, but also failed.

Then it was Shirnov who passed the first jump of 2.36 meters. This put pressure on Mason and Rebakov.

Next, the two made a second attempt at this height.

As a result, both of them failed in their second attempt.

"Mid-Autumn, are you feeling stressed now?"

The camera switched to the scene and Li Hong asked.

"No."

He Zhongqiu is very clear about his own strength. 2.36 meters does not challenge his limit and is even a long way from his current maximum height.

"I feel like I have secured the gold medal," Yao Ming said.

"It should be no problem. If we get this one, we will have three pieces for the Mid-Autumn Festival." Dazhi said with envy.

Guo Jing said nearby: "The focus is not on the gold medal, but on breaking the world record of 2.45 meters and the Olympic record of 2.39 meters."

"Yes, yes, it should be no problem for us to win the gold medal during the Mid-Autumn Festival." Xiao Huo quickly agreed.

Next, Mason and Rebakov made their third attempt at 2.36 meters.

The two had been jumping for two hours. Including 2.36 meters, Mason had tried six heights in total, and the number of attempts had reached 14 times. Rebakov had also tried six heights 13 times, and was very tired.

In this case, the third attempt failed as expected.

Yang Jian introduced: "Dear audience, now only Shirnov and Zhongqiu are left in the high jump final."

Han Qiaoshen said with a smile: "Zhongqiu only tried once, while Shirnov tried 6 times and passed all of them in one try. In terms of physical fitness, Zhongqiu should have the advantage."

Sun Zhenping said: "But we should note that there are too many events in the Mid-Autumn Festival, which consumes more physical energy, so the physical advantage is not actually a real advantage. It depends on the real strength."

"Yep."

Han Qiaoshen nodded repeatedly.

At this time, the camera switched and Li Hong appeared in the camera and said: "Dear audience, Zhongqiu just asked for a height of 2.40 meters, and it was directly raised by 5 centimeters."

"what?"

Yang Jian and the other two were shocked.

Han Qiaoshen immediately asked, "Li Hong, you have been with Cai Zhongqiu all the time, so you know him best. He was in closed training for 50 days before the Olympics, and you were the only one who went to the training ground. 2.4 meters, are you sure?"

Li Hong smiled and said, "I believe in his ability. 2.4 meters is not his maximum height."

The three of them breathed a sigh of relief. Yang Jian smiled and said, "Li Hong, I see you've seen him jump over 2.4 meters?"

Li Hong smiled and said again: "I can only say that 2.4 meters is not his maximum height."

The three of them were stunned for a moment, but they immediately realized that He Zhongqiu must have jumped higher during training, which made them excited.

At the scene, when Hillnov heard Wolverine asking for a height of 2.4 meters, the tremendous pressure pressed on his heart like a boulder.

2.4 meters. He jumped out during training, but not in actual combat.

He Zhongqiu started to prepare for a sprint. He took the water bottle handed to him by Feng Shuyong, took a sip, and immediately spit it out.

Ten seconds later, he started running.

"Let's start!" said Li Hong.

He Zhongqiu started from a straight run-up to an arc run-up and then jumped. As his body rose up, he still flew over the horizontal bar with a back-over style very lightly.

There was even at least five centimeters of space between his back and hips and the pole, so the 2.4-meter height was very easy for him.

"So easy?"

Shirnov's eyes narrowed.

"Ugh!"

He sighed. Although he would not give up the next attempt, he knew that it was impossible for him to jump over 2.4 meters.

"Oh!"

Huge cheers resounded throughout the Bird's Nest Stadium.

"Champion! It's decided! Zhongqiu is the champion! Champion! Zhongqiu broke the Olympic record of 2.39 meters." Li Hong shouted excitedly.

In the CCTV live broadcast room, Yang Jian said excitedly: "Great! Zhongqiu easily jumped over 2.4 meters, which means he is capable of challenging higher heights."

Han Qiaoshen said excitedly: "The Olympic record of 2.39 meters has been broken, and the next one is the world record of 2.45 meters.

My goodness, Zhongqiu kept his word. He said he would break six world records in track and field, and now he has started breaking them one by one."

Sun Zhenping said excitedly: "Looking at the slow-motion replay, there was still a few centimeters away from the pole, and it was very likely to break 2.45 meters."

"Yep."

Yang Jian said: "The pressure is now on Shirnov. He has to jump at least 2.41 meters to surpass Zhongqiu."

In the competition, Shirnov asked for 2.42 meters.

There is no point in asking for a lower height, the silver medal is already his. Wolverine's next jump will definitely be 2.42 meters. Considering that Wolverine just jumped over 2.4 meters easily, he will most likely pass 2.42 meters. So he has to jump over 2.42 meters at least to continue to compete with Wolverine.

However, the height of 2.42 meters was too difficult for him and he failed in all three attempts, thus ending his high jump final.

"Oh oh oh……"

He Zhongqiu was already the de facto high jump champion, and huge cheers rang out in the Bird's Nest.

Li Hong said happily: "Congratulations to Zhongqiu for winning the gold medal in the men's high jump. This is his third gold medal in this Olympics and his fourth individual Olympic gold medal."

"Next up is his personal performance time. He has already broken the Olympic record. Will he have a chance to break the 2.45m world record tonight and realize his dream? Please continue to look forward to it."

At this time, He Zhongqiu asked to test the jumping height.

After seeing this, Li Hong said excitedly: "2.46 meters, Zhongqiu asked for 2.46 meters, and next he will challenge the men's high jump world record of 2.45 meters."

"This is the third attempt tonight, the third attempt during the Mid-Autumn Festival, and we will start challenging the world record." Yang Jian shouted in the live broadcast room.

"Hope it works."

“Good luck to Mid-Autumn Festival!”

Han Qiaoshen and Sun Zhenping said excitedly.

At this time, the camera switched to the competition field. Yang Jian saw Li Hong's relaxed look and couldn't help asking, "Li Hong, what is Zhongqiu's best result in training?"

Li Hong laughed and said, "Let me put it this way, before the 50-day closed training, his best training result was 2.40 meters."

When the three heard this, they felt something was not right. How much improvement could be achieved in 50 days of blocking training? Are they sure they can reach a height of 2.46 meters?
Li Hong reminded him at this time: "Zhongqiu's high jump is mainly a technical issue. If his jumping ability is put on Shillnov, I think Shillnov can jump over three meters."

"Haha..." Han Qiaoshen and the other two burst into laughter.

They didn't find out how high He Zhongqiu could jump, but judging from Li Hong's words and expression, 2.46 meters should not be a problem to break the world record.

Another point is that Li Hong's words indicate a possibility that if He Zhongqiu's skills reach the world's top level of Shillnov, he can jump three meters.

"Teacher Han, what is Zhongqiu's current technical level?" Yang Jian asked immediately.

Han Qiaoshen thought for a moment and said, "It should have reached the first-class level. I think it's good."

Sun Zhenping said: "It's still a little short of being the top, but I think it's no problem to be first-rate."

“Good luck to Mid-Autumn Festival!”

On the court, Yao Ming and a large group of people shouted.

He Zhongqiu waved his hand and said confidently: "Wait for me to break the world record."

Two minutes later, He Zhongqiu's first attempt at a jump of 2.46 meters began.

"call!"

He started from a straight run to an arc run, and after taking off, he leaped over the horizontal bar with the sound of wind and with incredible lightness.

"Oh!"

In Wuchao, the National Stadium, the shouts of more than 90,000 people instantly rose to the sky.

Yang Jian shouted excitedly, "Broken! The world record is broken! 2.46 meters, Zhongqiu breaks the world record again. This is the third time he has broken the world record in this Olympics, and the third time he has broken the Olympic record!"

Han Qiaoshen laughed heartily and said, "Dear audience, just now, Zhongqiu successfully broke the men's high jump world record that had been untouched for 15 years."

Sun Zhenping said excitedly: "9.59 seconds, 9.35 meters, this time it is 2.46 meters, Zhongqiu has created a miracle again."

The camera switched, and Li Hong said excitedly: "Congratulations to Zhongqiu, but this is not over yet, the legend continues, because Zhongqiu has applied for a height of 2.5 meters again."

"2.5 meters?"

Everyone who heard it almost bit their tongue.

He Zhongqiu stood on the starting line again, preparing for his fourth attempt tonight.

When he was at level 85 in the high jump, his best training result was 2.4 meters. Now it is at level 90. Although it has only improved by 5 levels, he has risen from second-rate to first-rate level. The improvement is huge and there is a qualitative change.

His current best training result is 2.55 meters, which he has surpassed twice.

Of course, he is not going to challenge 2.55 meters tonight, he only wants to challenge 2.5 meters, and leave the heights beyond that to be broken slowly in the future.

His high jump is actually the same as his triple jump, which is greatly affected by his weight, but the impact is not as great as that of the triple jump, and is similar to that of the long jump.

So in this event, just like long jump, he has great potential.

"Let's start, 2.5 meters." Li Hong said loudly at this time.

He Zhongqiu took a straight run-up and then a run-up at the top of the arc. He jumped with all his strength and easily flew over the horizontal bar again.

"Oh!"

There was another huge cheer in the Bird's Nest.

Li Hong said excitedly: "It was very easy! Zhongqiu jumped over 2.5 meters. He succeeded in one go and broke his own Olympic and world record of 2.46 meters in the men's high jump."

He Zhongqiu waved to the stands, got off the mat, and said to the chief referee: "Sir, my trial jump ends here."

"Sure?"

"determine."

"OK."

"Great! I'm numb! 2.5 meters, Zhongqiu jumped over 2.5 meters very easily." In the live broadcast room, Yang Jian said excitedly.

“Looking at the replay, there was still a few centimeters of space and he could have jumped higher,” Sun Zhenping said excitedly.

Han Qiaoshen said in admiration: "It's very easy. Now I want to know, will Zhongqiu continue to challenge higher heights?"

At this time, the camera switched back to the stadium. Li Hong was interviewing He Zhongqiu. After hearing Han Qiaoshen's words, she immediately asked:

"Teacher Han, Zhongqiu has just given up the trial jump. He is a little tired."

"well."

Although He Zhongqiu gave up the attempt, the new world record of 2.5 meters was shocking enough and no one felt regretful.

Afterwards, He Zhongqiu stepped onto the championship podium for the third time, won his third gold medal, watched the national anthem play for the third time, and raised the national flag for the third time.

This is also the 46th gold medal for the Chinese team.

After the award ceremony, we celebrated for a while and then returned to the Olympic Village. It was already one o'clock in the morning. There will be the 200m final tomorrow morning and the men's basketball quarter-finals in the evening. I took a shower and went to bed quickly.

On the 20th, at 10 a.m., He Zhongqiu had been warming up for half an hour, and the 200-meter final was about to begin in 15 minutes.

He Zhongqiu adjusted the running gear and tried to start several times.

The same went for Bolt next to him, who glanced at He Zhongqiu from time to time.

He admired Wolverine beside him so much. He won the 100-meter championship, the long jump championship, and the high jump championship, and broke all the world records and Olympic records. How could there be such a person in the world?

The 200 meters is his main event. His best training result is 19.25 seconds, which is about to break the world record. He is very confident.

He will definitely not give up on this event. He wants to snatch the 200-meter gold medal from Wolverine.

"Usain, don't be distracted, otherwise your chance of winning the gold medal will only be in the 4x100m," He Zhongqiu reminded.

Bolt was startled and nodded quickly.

The men's 200 meters is one of the most exciting and most watched events in track and field, besides the 100 meters.

There are many big-name stars beside the track.

Michael Jordan, O'Neal, Maurice Greene who announced his retirement in BJ in February this year, Michael Johnson, the world record holder for 200m and 400m, Gatlin who was banned by the IAAF, and many others came to watch the game.

CCTV camera switched to the stadium. Li Hong came over with a camera to interview Michael Johnson and asked:

"Mr. Johnson, Wolverine has broken three world records and Olympic records in a row, and even ran the 9.6 meters in 200 seconds. Do you think he has a chance to set a new -meter world record and Olympic record?"

Michael Johnson's attitude is now more cautious than before. The reason, of course, is that He Zhongqiu ran the 9.59-meter time in seconds.

He couldn't possibly belittle the fastest man on the planet; that would only make him seem ignorant and petty.

Before the high jump and long jump finals, he could still make fun of He Zhongqiu's bold statement of breaking six world records in track and field events, but as He Zhongqiu broke the world records in long jump and high jump again, he could no longer make fun of it.

But he still had a bit of a tough talk, saying, "The 200 meters is different from the 100 meters. Wolverine has not proven himself in the 200 meters so far, and his best time is only 19.7 seconds."

"But I'm also looking forward to his performance. He is one of the greatest track and field athletes in the world."

"Thank you Mr. Johnson for accepting this interview."

Li Hong ended the interview and said to the camera: "Dear audience, the men's 200m final is about to begin."

"The current wind speed is headwind, -0.3 meters per second, which meets the competition standard."

"Zhongqiu's best 200m result is 19.70 seconds, which was the result of last year's Shanghai Golden League. Being able to run under 20 seconds is already a world-class level."

"After a year of training, I believe his 200m strength has improved a lot and he has the potential to win the gold medal."

"In the 200m event, Chung-Qiu's strongest rival is still Bolt."

"But Zhongqiu's goal is to break world records and Olympic records. His real opponent is actually himself, not his opponents."

"The 200m world and Olympic record is 1996 seconds, set by Michael Johnson at the 19.32 Atlanta Olympics, and it has been untouched for 12 years."

"Now let us wish him the best and hope that he can win gold again and continue his great miracle in track and field."
