The 100m race hadn't started yet . The eight partic.i.p.ants were just on their tracks to make preparations . At the same time, the audience were all talking about Jimmy Aylwin's most recent victory .

What the common audience saw was Aylwin's comeback to win the 400m race . But professionals focused on his score of 43 . 82 seconds .

In the TV studio, the commentator with ESPN couldn't help saying, "Aylwin is still so fast! It's beyond my imagination that a 34-year-old coming back three years later after retirement can still finish the race within 44 seconds . His physical condition has seen no decline through four years . I really want to know his secret of keeping such a good physical condition!"

The question of the ESPN commentator was also confusing many coaches . In their opinion, it was impossible for an athlete aged 34 who came back after three years of retirement to get a score of 43 . 82 seconds . They would consider it a delusion if they hadn't seen it with their own eyes .

"How did he do that?" Every coach on site couldn't help thinking about it . Many coaches were discussing it .

. . .

"To tell you the truth, I think there are two possible reasons for Aylwin to keep so fit . One is that he was born physically gifted . There are some people who are born to run faster and jump higher than others . It's impossible for an ordinary person to copy the brilliance of a talent," a black coach said . He added after a pause, "The second reason may be the training . A more scientific training method can keep the athlete's physical condition good . "

But a Spanish coach beside him shook his head to say, "The training? That's hardly possible . That's a score of 43 . 82 seconds . A 34-year-old sprinter must have gone through a severe physical degeneration . No training will help . Training can make a man stronger, but it cannot rejuvenate him . So, I believe in your first inference that Aylwin is gifted just like the mutants in X-Men . He is unique and cannot be replicated . "

"Your words about rejuvenation remind me of another man . Do you remember the boxing king, Kevin Taylor? Everyone was optimistic about his comeback . Taking his age into consideration, all people thought it was impossible for him to fight so aggressively . But the reality, Taylor shows a better physical condition than before . It's a real rejuvenation," a coach with a beard said .  

"Maybe that's just a coincidence," the Spanish coach denied stubbornly . "And boxing is different from sprint . There are many professional boxers in their forties . But sprinters are considered old athletes when they are more than 30 years old . " 

"But Ted's way was in pursuit of extreme explosive force, which is similar to the aim of sprint," said the coach with a beard . He seemed like he might have a problem with the Spanish coach .

"Okay . Let's suppose you are right . Training can rejuvenate athletes . Could you please tell me what kind of training can achieve that? No? So, Kevin Taylor and Jimmy Aylwin today are both just unique cases . Never forget that we are just coaches . We cannot beat time!" the Spanish coach said .

"If I may speak," the black coach who started the topic interrupted the two, looking at his mobile phone . "According to my search just now, Jimmy Aylwin's fitness coach is also Kevin Taylor's fitness coach . "

"So, this coach has helped two athletes regain youth?" the bearded guy said with the expression of someone who had just won an argument . And he added, "One athlete's rejuvenation can be called an isolated case . But I don't think we can still use the term 'isolated case' since we have found the shared key point in the two cases . "

The Spanish coach asked skeptically, "Who is that coach?" 

"Dai Li, and you must have heard of him . Chinese names are few in our field," replied the black coach .  

"It's him! The man in Los Angeles!" Obviously, the Spanish knew Dai Li .

"It's him! The man in Los Angeles!" Obviously, the Spanish knew Dai Li .

Track and field were traditionally the weakness of Asians . Asian coaches were fewer than pandas . So, everyone knew of Dai Li .

"As far as I know, he is also the coach for the 'Blade Runner,' Philip . I met Dai Li in the last World Champions.h.i.+p tryout," the coach with a beard added .

"Philip, Taylor, and now Aylwin . Their achievements cannot be a.n.a.lyzed by common theories . They are not isolated cases . This Coach Li must have a special way of training . " The black coach paused and then he said, "I think he really has beat time to some extent!" 

. . .

Sebastian's expression was very serious . Aylwin's score of 43 . 82 seconds went beyond his imagination . He believed that Dai Li had a more effective new drug .  

I must have that new drug! And I'd better get it before the Franklin Lab gets it . And I can make an exchange with the Franklin Lab to get benefits . I must figure out a way . From his seat on the main stand, Sebastian looked over the coach rest area by the side of the field and found Dai Li .

Asking Dai Li directly will not work . No coach will admit he provided drugs for athletes . That's silly . And even if he admitted it, he would never give it to me . A new type of drug, which is so effective . That's priceless .

So, I need to think of something to make Dai Li give it to me . If I can find the evidence of his providing drugs to athletes, I could threaten him with it to get the new drug . If he refuses, I could take it public to make him notorious . Okay . Good idea! And a direct one! 

But the problem is how to find the evidence? Should I hire an investigation company? The Franklin Lab has done that, but it hasn't got any information . And nothing was found in the urine samples of Alexander and Ford after several rounds of tests . And I think they would be equally useless on Aylwin .

But the problem is how to find the evidence? Should I hire an investigation company? The Franklin Lab has done that, but it hasn't got any information . And nothing was found in the urine samples of Alexander and Ford after several rounds of tests . And I think they would be equally useless on Aylwin .

Or should I talk with athletes to seek some information? No . They are athletes, not fools . Admitting that they used drugs would be too silly . Their mouths are zipped on the issue of drugs . It's meaningless .

What should I do? Sebastian thought .

I know! The urine test found nothing, but other tests may find something . The blood test! But it's very complicated to set up a blood test… Suddenly Sebastian got an idea .

That's fine . I am the Chief Coach of the National Track and Field Team of America . Winning the qualifications, Aylwin and Alexander are all going to be promoted to the National Team soon . It will be so easy to get the blood samples when they are all under my control .

Thinking of that, Sebastian smiled happily .

. . .

Under most circ.u.mstances, athletes were required to take urine tests . Some migh be asked to take blood tests . But there were just few cases of blood tests . Take the International Anti-Doping Organization for example; during ten years, it set blood tests for only 5000 athletes, most of which went through batch tests . Many high-level professional athletes needn't take blood tests for several years .  

When athletes used drugs, the metabolites of the drugs would be conveyed through the blood to the organs and tissues where they would function . So, the blood test was quicker and more accurate than the urine test . The urine test just examined the metabolic waste of humans, but the blood test was a real-time test of athletes' usage of drugs .

Many illegal drugs, including peptides, some kinds of hormones, erythropoietin, the human growth hormone and so on, could not be found by the urine test . Because they were natural hormones of the human body and so were their metabolites . The urine test couldn't identify the evidence of those drugs as long as the hormones didn't exceed the limits too much . But the blood test could solve this problem .

The blood test was more accurate, but its process was very complicated . According to the IAAF regulations, reasonable cause and a written notice with the athlete's personal signature for confirmation must be presented for a blood test . It was more complex than the urine test .

According to the rules, athletes were allowed to refuse to offer their blood samples immediately, as long as they offered the samples within one week . So many changes could take place in one week with current technologies .

And the athletes had to hand in the list of drugs they used over the last ten days and records of any blood transfusions in the last six months . The two requirements gave the athletes room for playing tricks . Some of the athletes might make deals with doctors to give themselves a temporary prescription to confuse the results of the blood test .

Because of all of the reasons above, the blood test was not a usual option . Generally, only when an athlete was under suspicion of using drugs, or when the athlete was the top three of a high-level compet.i.tion such as the Olympic Games, would blood tests happen . Usually, the urine test could solve all problems .  

. . .

Having made his plan, Sebastian relaxed to refocus on the field .

The 100m race was going to begin . And his student, Warton, "the Miami Hurricane," would take part in the race .

Warton made great efforts these last two months . I think he will not be defeated by Alexander .

The 100m race hadnt started yet . The eight partic.i.p.ants were just on their tracks to make preparations . At the same time, the audience were all talking about Jimmy Aylwins most recent victory .
