"Upgrade, this time it's a first-class coach!" Li Dai was full of joy, and his mouth began to hum a little tune. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Li Dai has been promoted to a first-rate coach by a second-rate coach, and he is now in the initial stage of a first-class coach.

For this promotion, Li Dai waited for a long time, the last time he was promoted to the advanced stage of a second-rate coach, he had just finished Lin Feixiang's training, and now it has been nearly two years.

In the past two years, Li Dai has led the team and trained every day, brushing up on his experience in obscurity, and his experience points have slowly increased, and sometimes he even forgets that there is a system.

The experience gained from training young athletes is really very limited, and if it weren't for this time to the national team, Li Dai might have to wait a longer time to upgrade.

Looking at the title of "first-class coach" in the system, Li Dai felt a sigh in his heart, he remembered that when he just got the coaching system, he received a first-class coach experience card given by the system to newcomers, and he was still amazed at the power of first-class coaches, and now, he has really become a first-class coach.

"Reward! Reward! My reward! This time, I was upgraded from a second-rate coach to a first-class coach, and I should be given an upgrade package with two rewards! Li Dai said to the system with some expectation.

The system will indeed send the upgrade gift package. After the upgrade package was opened, two items appeared inside, both of which Li Dai had seen, one was an aperture and the other was a chip.

Li Dai has obtained these two things, the shape of the aperture and the explosive aura are the same, but the color is different, indicating that this is also an aura. And the chip-like thing, Li Dai also once obtained, which is the detector upgrade kit.

"Aura, finally another aura!" Li Dai looked at this small aperture, full of joy, and now Li Dai has already deeply felt the power of the aura.

When he was at the Beikou training base, Lin Feixiang defeated Dong Teng, who had a higher ability value than him, with the advantage of explosive aura, and later broke the world record for the second time.

When the youth track and field team was in the youth track and field team, Chen Jiankang and other five people also relied on the aura of explosive power to defeat the strong opponents visited by Nantan Middle School.

Fang Haiquan defeated Yang Gang in the Youth Games, and he also has the credit of an explosive aura.

Compared with those skills, halo skills are continuous bonuses, and they are also effective in groups, and for Li Dai, he only needs to equip the aura into the system to have an effect, and he is not allowed to do actions such as applauding and shouting cheers, which is also more convenient than those skills.

"What kind of aura is this?" Li Dai asked.

"Endurance aura, as the name suggests, is the aura that enhances the endurance of athletes!" The system opened his mouth to explain.

Li Dai immediately thought of the middle-distance running event.

In middle-distance running, the importance of an athlete's endurance is self-evident. Middle-distance running cannot be like sprinting, desperate to sprint forward, especially in high-level competitions, often until the last lap to determine the winner, at this time who has more physical reserves, whose muscle fatigue is lighter, who is likely to become the ultimate winner.

Then, Li Dai thought about football again. In a football game, counting injury time, it will definitely be more than 90 minutes, and it will be played until 120 minutes in extra time, and the players have to run on the pitch for such a long time, and the side with stronger endurance will have a great advantage in attack and defense and tactical coordination.

Immediately afterwards, Li Dai thought of some other sports that require long runs, and the demand for endurance is very large.

At this time, the voice of the system interrupted Li Dai's thoughts: "You already have an explosive aura, and you have fully experienced the effect of the explosive aura. So about the endurance aura, I only explain one point here, the endurance aura can not only increase the muscular endurance of athletes, but also increase the cardiovascular endurance of athletes! ”

"Even cardiovascular endurance can be increased!" Li Dai was really taken aback this time.

Muscle endurance refers to the body's ability to perform continuous muscle work for a long time, simply put, the ability of muscles to fight fatigue. After a long period of exercise, people will feel fatigue, and this feeling is mainly muscle fatigue. People with stronger muscular endurance can better combat fatigue and can naturally stay in exercise for a longer time.

Cardiovascular endurance is the body's ability to inhale, transport, and use oxygen. The greater a person's ability to inhale, transport, and use oxygen in a given period of time, the better his cardiovascular endurance.

At the same time, cardiovascular endurance also affects the energy supply of phosphogen and glycolysis, both of which are basic fuels for the body's movement.

Li Dai originally thought that the endurance aura only increased muscular endurance, but he didn't expect that it could also increase the cardiovascular endurance of athletes. Muscle endurance and cardiovascular endurance go hand in hand, and when the two are combined, the results are not as simple as one plus one equals two.

"Sure enough, the Halo prize is the best!" Li Dai couldn't help but sigh in his heart.

Then Li Dai looked at the chip again.

"This is an upgrade kit for the Observer, right?" Li Dai asked.

"Yes, this score kit can upgrade your Observer to an Advanced Observer." The system replied.

"When the beginner detector is upgraded to the intermediate detector, I can see the talent of the athletes, so what new effects have been added to the advanced detector?" Li Dai immediately asked.

"Advanced Detector, your detection range can be increased by 20 meters from the original!" The system said right away.

"Oh." Li Dai agreed without nutrition, he was not too interested in the increased detection range of 20 meters.

"In addition to this, advanced detectors can detect strengths and weaknesses in athletes." The system continued.

"What do you mean?" Li Dai sensitively noticed that this seemed to be a rather anti-heaven effect improvement.

"You probably won't understand too much just by relying on my introduction, but I suggest you find an athlete and detect it. Anyway, the most important thing in the national team is athletes. The system spoke.

"That's right." Li Dai nodded, and then upgraded the detector under the guidance of the system, and then planned to find an athlete to try the effect.

In the training base of the national team, there is no shortage of athletes, and Li Dai's opportunity to go to the bathroom blocked an athlete who came to the bathroom.

"This athlete seems to be practicing long jump, I saw him in the long jump group, so I chose him, detect!" Li Dai used detection on the athlete.

In the next second, a large row of information appeared in the system, the first two lines had the same effect as the previous detection, but the last two lines made Li Dai not calm.

Detection Target: Professional-level athletes;

Professional events: pole vault; Professional Ability: 494; Talent: C+

Advantages: excellent physical flexibility, strong sense of rhythm of running, sufficient take-off......

Disadvantages: lack of grip strength, weakness on the pole, large difference in grip strength between both hands, and the grip strength of the right hand is significantly smaller than that of the left hand......

"OMG!" Seeing this detection result, Li Dai realized that the advanced detector was the real anti-heaven artifact!
