Kawajiri Kensaku, standing in the back, was dying to say something.

From the moment Chen Yu took out the Small Needle Knife, he had been itching to raise his hand and shout, ’Look, I know what that is! It’s Acupuncture!’

But then, after seeing Chen Yu inject an anesthetic and use the steel needle to release the fascial adhesions, Kawajiri Kensaku was completely dumbfounded.

He had no idea Acupuncture could be used like that.

So, without waiting for Chen Yu, he eagerly stepped forward and asked why Acupuncture could be used in such a way.

Chen Yu was aware that traditional Chinese medicine was popular in Japan.

Speaking of which, Chen Yu also found it both puzzling and regrettable. Treatment methods related to traditional Chinese medicine, like Acupuncture and herbal formulas, were all invented in China. So why were the vast majority of Chinese medicinal herbs in the United States produced in Japan?

"This isn’t Acupuncture in the traditional sense. It’s an acupuncture-based therapy invented by Chinese doctors called the Small Needle Knife. I learned it a while ago when I went to China to study," Chen Yu said, casually handing him a Small Needle Knife to examine.

Then, Chen Yu took out a steel needle to sterilize it and said to a bewildered Wolffat, "Wolffat, you can think of it this way: it’s as if I used a scalpel to pierce the area of adhesion and perform a dissection surgery."

Once he put it that way, Wolffat immediately understood. He then grinned and said, "But that would be incredibly difficult. The technique is crucial."

Working through the skin, you can’t see anything. Cutting blindly would only cause more problems.

It would be difficult even while watching with a B-scan ultrasound.

He knew human anatomy like the back of his hand, but if he imagined himself in Chen Yu’s position, he wouldn’t dare to do it.

Yet Chen Yu had done it. This could only mean that Chen Yu’s grasp of human anatomy was far superior to his own.

’A master, a true master!’

Wolffat looked at Chen Yu again, his eyes shining. He had truly seen something special today.

Chen Yu nodded in agreement. "That’s why, although this treatment method is convenient and effective, I really don’t recommend it for anyone who lacks experience or a deep understanding of human anatomy."

Chen Yu then gestured for Ballack to sit properly and extend his left arm.

"Next is Acupuncture. I mentioned earlier that you could use other methods to replace the extract injections. Acupuncture is one of them. It can stimulate blood circulation and activate the immune system’s self-healing capabilities."

As he spoke, he began inserting the needles.

It was the same old principle: treat the foot by needling the hand, treat the right by needling the left.

When the first needle went in, not only was Ballack stunned, but Wolffat was also completely baffled. He really wanted to remind Chen Yu that he might have made a mistake—the injury was to the foot.

However, Kawajiri Kensaku’s eyes lit up beside them. He exclaimed as if he’d had an epiphany, "My God, I get it! This is the Qi-reversal theory from traditional Chinese medicine!"

"The what?" Wolffat was completely lost.

Chen Yu glanced at Kawajiri Kensaku out of the corner of his eye. ’This guy knows quite a bit. He even knows about Qi-reversal theory.’

Bursting with the need to explain, Kawajiri Kensaku hurriedly elaborated for Wolffat, saying it was one of the most profound medical theories in traditional Chinese medicine, originating from the *Inner Canon of the Yellow Emperor*. He explained that the entire human body is a balanced, organic whole, and treatment should be applied to the opposite location.

His English vocabulary was limited, and in his haste, he couldn’t translate some of the professional terms. Even if he could, Wolffat wouldn’t have understood them anyway.

In the end, all he could do was wear an expression that said, "It’s just really awesome," and give Chen Yu a constant stream of thumbs-ups.

Even in Japan, where traditional Chinese medicine was prevalent, not many people could fully grasp this concept.

Wolffat only understood half of it, but as someone who could extract substances from rooster combs and various plants, he was clearly open to new ideas. His comprehension skills were also explosive. With a look of sudden realization, he said, "Chen, I understand. His right ankle is injured, so you’re performing Acupuncture on his left hand."

As he spoke, he even gestured up, down, left, and right.

He used the word "Acupuncture" correctly, so he clearly knew what it was.

After all, when Acupuncture was first introduced to the West, it was in Europe.

The same went for Moxibustion, which was accidentally discovered by missionaries in the 17th century and brought to Europe to treat gout, the "disease of kings."

So, it wasn’t at all strange that Wolffat knew about Acupuncture.

Chen Yu nodded. "But this subject is very complex. If you want to learn it, I suggest you study Chinese first—and you’ll need to become very proficient."

The classical Chinese texts are not something you can understand with just a rudimentary grasp of the language.

As he spoke, Chen Yu continued inserting needles. Soon, Ballack was covered in them like a porcupine. His limbs stiffened, and he was too scared to move a muscle.

Marco Reus, watching from the side, silently rubbed his shoulder. ’An ailment on the upper body is treated on the lower body...’ He looked down and couldn’t help but shiver.

Wolffat watched intently, his interest piqued.

The Acupuncture therapy had a huge impact on him. He had never imagined that there was a method that could accelerate blood circulation and activate the body’s self-healing ability simply by stimulating specific points.

’If I had known about this method, why would I have bothered with all those extracts? Did I really think that stuff was so great? Rooster comb blood... people could easily think I’m a weirdo.’

A moment later, Chen Yu removed the needles and stopped.

"Actually, methods like Acupuncture, cupping, and even localized bloodletting can all help promote blood circulation, accelerate the clearing of inflammation, and aid the body’s self-healing." Chen Yu then began a physical therapy massage with his hands.

By now, the effects of Ballack’s anesthetic were slowly wearing off. As feeling returned, he felt Chen Yu’s fingers kneading his muscles and instantly understood why Desler and Scholl had always said that receiving a physical therapy massage from Chen Yu was pure bliss.

After the sprain, the injured area had been numb. But now, it felt like the blissful release after a muscle cramp—a tingling, thoroughly relaxed sensation. If there weren’t so many people around, he would have cried out in comfort.

"Of course, medication is also crucial," Chen Yu added.

Acupuncture and massage are auxiliary therapies. If you’re sick or injured, you still need to take medicine.

’Of course, the most important thing is the system’s effect. That’s the real invincible, divine tool.’

Wolffat nodded repeatedly. From this perspective, Chen Yu wasn’t limited to a specific therapy but was integrating Chinese and Western medicine, considering the problem from a holistic, overall perspective.

"Chen, today has been a real eye-opener. I’ve learned so much," Wolffat said with emotion.

Before, he had just witnessed it; now, he felt he had truly learned from it.

Beside them, Kawajiri Kensaku was also nodding emphatically, excitedly wanting to say that he had learned something too.

Chen Yu stopped and asked Ballack how he felt.

"Comfortable." A thousand words coalesced into one. Ballack gave a thumbs-up, then tried to stand up. He walked a few steps in place, moved his ankle around, and said in pleasant surprise, "I feel like my ankle barely hurts at all."

The pain before was like a hidden needle in the flesh—not intense, but always there, like having a pebble in your shoe, a constant discomfort.

But now, that discomfort was completely gone.

Without another word, Wolffat started clapping.

Everyone else present immediately joined in.

Chen Yu waved his hand dismissively. ’It’d be a miracle if the effect wasn’t good. After all, I even applied a Bronze-level recovery effect.’

"Go get an X-ray," Chen Yu instructed Ballack.

The proper procedure still had to be followed.

Then he said to Wolle, "His injury isn’t serious, but I’d still suggest he rests for one match and returns for the second game on June 5th. I believe this would be the best choice for both him and your team."

They played Saudi Arabia on June 1st and Ireland on the 5th. Resting for one match meant an extra four days of rest.

It was only Saudi Arabia. At the Germany Team’s level, they could afford to rest not just Ballack, but their entire starting midfield, and still beat them 5-0.

Wolle nodded. Whether he rested or not was another matter, but even if it was the same advice, hearing it from Chen Yu felt reassuring and convincing.

Chen Yu then turned to treat Reimer’s condition.

His problem was even more minor—a rotator cuff strain, a straightforward physical injury.

Chen Yu used his usual method: Acupuncture plus massage.

After all, with his skill bonus, even without applying a recovery effect, the treatment was extremely effective.

After the simple treatment was finished and Wolffat saw the angle to which Reimer could now raise his arm, he couldn’t help but give another thumbs-up.

He was an expert in physical therapy massage; not a single player he had massaged had anything but praise for it.

But today he realized that compared to Chen Yu’s massage, he still had a long way to go.

Both players had minor issues, so Chen Yu dealt with them quickly.

In fact, today’s treatment session had mostly turned into a discussion with Wolffat.

"I’m actually not a big fan of surgery," Wolffat said with a slight frown.

He had practiced medicine for many years, and his guiding principle was to avoid surgery whenever possible, as he always felt it was too invasive.

Chen Yu gave a noncommittal nod.

Whether to operate or not depended on the situation.

If surgery could be avoided, he certainly wouldn’t perform it. There was even a concept in traditional Chinese medicine theory that surgery damages one’s vital energy.

But in some cases, like a ruptured ligament or Achilles tendon, you couldn’t possibly expect it to heal on its own. Surgery was necessary when it was necessary.

But Wolffat was someone who truly understood.

In the past two years, Chen Yu had met many team doctors, but most were just that—doctors. When they treated players, they only isolated the injury itself for treatment.

But athletes are special, or rather, completely different from ordinary people. To treat them, you have to consider not only curing the ailment itself but also their sport.

It’s called sports medicine. Sports comes before medicine.

Therefore, treatment needs to be integrated with training, and better training can also prevent injuries from occurring. In this respect, of all the team doctors Chen Yu had met, Wolffat was the most knowledgeable.

No wonder he could work at Bayern for so many years.

Of course, limited by the fact that he didn’t have a "system," he could never reach Chen Yu’s level.

Otherwise, would Scholl have come all the way to the United States to find him?

Since he had to get back to watch the game, Chen Yu didn’t stay long and prepared to leave.

However, just as he was about to go, Wolffat suddenly stopped him. "Oh, by the way, Chen, I read a report from the United States that said you once treated an NBA star named Tracy McGrady or something like that. It said you treated him, that he had some degree of congenital scoliosis, and that you helped him with the problem."

"And you also helped Scholl with his spinal disc problem. So you must know a lot about treating the spine, right?"

’He must be talking about T-Mac,’ Chen Yu thought. The media had indeed reported on Tracy McGrady’s scoliosis, and McGrady himself had told reporters that his condition had been alleviated after Chen Yu’s treatment.

After all, he had been playing with a back brace all season; there was no way the media wouldn’t notice.

And this summer, he was planning to come to Phoenix to have surgery to resolve the issue completely.

"That’s right. Why?" Chen Yu asked in return.

Wolffat explained, "Well, back in April, I met a young man who’s a sprinter. His coach wanted me to evaluate his athletic talent, and I discovered that he has a certain degree of scoliosis. I’ve been thinking about how to train him more scientifically to manage this issue, so I wanted to ask for your thoughts."

Chen Yu nodded. If someone’s scoliosis was congenital and irreversible, their training certainly required special consideration.

"By the way, what’s his name? A sprinter, you said?" Chen Yu asked casually.

Wolffat nodded. "Yes. His name is Usain Bolt. He came to see me to prepare for this year’s World Junior Championships. I think that kid is a genius; his physical condition is incredible."

’Bolt?’

Chen Yu had no idea who that was. After a moment’s thought, he said cautiously, "Spinal issues are very complex and have a significant impact. How about this: if he needs it, you can have him come find me in the United States, and I’ll take a look at him then."

After speaking, he waved goodbye and got in the car to leave.

The game was about to start over there.
