Ruby noticed that white dots began to ooze from her skin.

These white dots are mucus and very viscous.

"What's this slime?" Ruby reached out and wiped it.

"This is lactic acid, lactic acid is secreted when the muscles are active vigorously, and it is also the reason why you cause soreness after strenuous exercise, but lactic acid is consumed by the cells, and when lactic acid is consumed, the soreness disappears. Chen Cao said.

"Is there a way to stop the secretion of lactic acid?"

"There is a way, but you can't do it, lactic acid secretion is necessary, because lactic acid can repair the damage to your muscles, and it also reminds you of the load level of your body, without lactic acid secretion, you may be able to become superman in a game, but after the game, your career will be over. ”

"So is it okay for you to force lactate out now?"

"Are you active now?"

Ruby shook his head, and Chen Cao said again: "And what I forced out was the lactic acid you secreted during the previous competition, if you continue to exercise now, you will still secrete lactic acid, I just forced out the excess lactic acid in your body, not to stop your lactic acid secretion." ”

"I see. ”

"Is that every time it's over, you can help me relieve my tiredness?"

Chen Cao pinched Ruby's biceps and said: "It depends on the situation, lactic acid is not a harmful substance, if you run the whole race, then it is not suitable to force out lactic acid, and I can prescribe you a recipe, which can greatly increase your post-race recovery." ”

"Okay, how much?"

"I don't want you to pay for this, but you have to promise me one thing. ”

"You still want money. Ruby didn't dare to agree to Chen Cao casually.

After all, he didn't know what Chen Cao's request was, although his brain was not very bright.

But he knew that there were some things that he couldn't just promise.

"I'm a professor at the University of Los Angeles, and after a while, our school has a sports day, and I'm the leader of our school, and you go and give a few lessons to our school's basketball team. ”

The NBA is the best basketball player in the world.

Basketball players who can make it to the NBA, even if they are just benches, are considered top players in other competitions.

What's more, Ruby is also a top star in the NBA.

So Chen Cao believes that if Ruby can go and give a few lessons to those basketball club students.

Tell them about his experience and they will grow a lot.

"Just a few lessons?"

"Of course, I won't ask you to do anything else than that. ”

"It's time outside of training and games. Ruby said.

"No problem. ”

"Yes, do you want to sign a contract?"

"No, it's our verbal agreement. Chen Cao said: "But I have never been a good person, and I hate it when others break their promises." ”

"Of course, I understand, it's just a few lessons, and I'm not going to break faith about it. ”

After giving Ruby a treatment to relieve muscle fatigue, Chen Cao treated Kohler.

Chen Cao had already treated Kohler once, so Kohler was also very proficient.

After leaving Kohler's home, Chen Cao went straight home.

Chen Cao explained the situation to Fa Li, and he was going to leave for a few days.

......

The next day, Chen Cao went to school again.

"Robert, I have found a professional player, and he will come to the school in two days to give guidance to the players of the basketball club, and he will contact you when he comes, and you will be responsible for arranging it then. ”

"Got it, Mr. Chen. ”

Since Robert was taught by Chen Cao, he has been like a grandson in front of Chen Cao.

In fact, Robert was used by Chen Cao to kill chickens and monkeys.

Don't look at the people in the school who are polite to themselves on weekdays, but there are few who really obey themselves.

In particular, Wright arranged for himself to be the team leader, and many physical education teachers in the physical education department disagreed with this.

Robert is just a budding bird, if Chen Cao didn't teach Robert a lesson.

It is expected that more coaches or PE teachers will join forces to put pressure on the school.

At that time, Wright is estimated to be forced to remove Chen Cao's identity as a team leader.

Chen Cao can not care about the identity of the team leader, but Chen Cao doesn't like the way he is driven away.

Since Chen Cao used a domineering method to teach Robert.

Chen Cao also has a nickname, Tyrant.

Of course, those who have secretly united have also died down.

However, Chen Cao felt that this nickname seemed to suit him quite well.

At this moment, Chen Cao saw Tiger walking over.

"Hi, Mr. Chen. ”

"Tiger, congratulations, you got last year's BA belt. Chen Cao went up and patted Tygo's arm.

"Mr. Chen, it's all your cultivation. "Tygo is now famous.

But he knows better that it is Chen Cao's help that makes him what he has today.

Of course, he knew that he was not qualified to betray Chen Cao.

The consequences of betraying Chen Cao were very serious.

Chen's record is much more than just knocking out Douglas.

Chen Cao was in front of him, crippling and killing more than a dozen thugs of underground dealers.

Tiger still remembers that night vividly.

Even if the current Tiger is the new boxing champion, he will not be naïve to think that he is Chen Cao's opponent.

Not to mention Chen Cao, even Gaia, he may not be able to fight.

"Tiger, why are you here?"

Tiger hadn't finished his studies yet, but he had already taken a year off.

"It was the principal who asked me to come back, and she told me that you are the leader of this sports meeting and that she wants me to participate in the boxing competition of this sports meeting. ”

"Will there be a boxing match at the Games?" Chen Cao asked with his mouth open, stunned.

"Well, the boxing match of this Games is sponsored and televised, and the scale is relatively large. ”

Chen Cao didn't expect that the American college games would be so commercialized.

"In addition to that, there seems to be sponsors for swimming competitions as well. ”

Tiger also knew that Evelet had been cultivated by Chen Cao.

Tiger hopes that he can become the next Evelet.

A new legend in the boxing world, and if you want to accomplish this goal, then Chen Cao's support is indispensable.

"Did you train at school during this time?"

"Yes. Tiger nodded: "Mr. Chen, do you have time to train me?"

"Not in the past few days, I'm going to go out for a few days, and I'll talk about it when I come back. Chen Cao said.

"Oh well. ”

"By the way, there are some people in the school who are not very satisfied with me as a team leader, and help me watch the dots. ”

"Mr. Chen, I'll help you teach those bastards who don't have long eyes. "Tiger is in the boxing club, and the students in the school belong to the status of the boss, and there are really not many people who dare to choke with him.

"No, just help me write them down, and I'll clean them up one by one when I come back. ”

"Okay, I see. ”

At this time, Chen Cao saw that Li Qiong was not far away, and there was another girl beside her, who should also be a student in the school.

"You go to training first, and I'll talk to you when I have time. ”
