Ke Xue: He mastered the steel-cutting divine skill at the start.

"The sound of a heartbeat? Xiao Lan from two months ago?"

This made Sera Masumi feel a chill run down her spine.

Although I made some judgments based on my mother's words and her so-called information, and trained myself to avoid giving anything away by noticing a lie detector test.

After all, in her eyes, this Miyazaki swordsman was practically a walking lie detector, since being able to detect unusual and subtle fluctuations was a terrifying ability in itself.

Now that Miyazaki Yu has said it himself, Sera's heart trembled even more.

Xiao Lan, who was standing to the side, could guess what Shi Liang was thinking after seeing her appearance.

"Xiaoyu, don't say things like that right away. Sera is very strong. I might not be able to beat her."

Although they had only spent a few days together, Beika Town was prone to disasters, and accidents happened frequently, so there was no shortage of opportunities to intervene.

Therefore, Xiaolan had witnessed this girl's attack; her swift and fierce strikes left a very deep impression on her.

Miyazaki Yu smiled faintly, not caring. Ran was a naturally gifted player, just like in the original timeline.

Even without the guidance of a master, he was able to cultivate to a very high level, making him an absolute standout among ordinary people. He was also the only person besides Makoto Kyogoku to successfully dodge a bullet.

As someone once said, a gun is accurate and fast within five steps, but there are always people who can break this rule.

With the meticulous training of the great swordsman Miyazaki Yu, Ran is now a completely different person. Although she is still far behind strong swordsmen like Kyogoku Makoto and Akai Shuichi, Sera Masumi is no match for her at all.

"I was just estimating, so please don't take it seriously."

Sonoko smiled and said, "I knew it. No matter how good you are, you can't determine a person's strength just by looking at them. By the way, where did Lingyu go? I heard from Ran that the little guy did a great job. I never thought he was that strong. I have to study him carefully this time."

After looking around, I spotted a kitten that had curled up and was sleeping on top of a sword rack, and my eyes lit up.

Sera Masumi had also heard Ran mention that Miyazaki Hayao owned a very powerful calico cat that not only had two tails but could also use a claw to sever a person's hand.

This was something she had previously considered beyond common sense. While felines are agile, neither their size nor their claws could possibly possess such power.

But after coming here today, I've come to believe it a little. It's not so unacceptable that such amazing people could raise such amazing animals.

"Meow—"

Lingyu had just fallen asleep when Yuanzi woke her up. She couldn't help but roll her eyes at the woman. This woman loved petting cats the most, and would do all sorts of things to her whenever she saw her. If she weren't already almost a demon, she would be bald by now.

"I've heard a bit about this kitten. It's really amazing. No wonder it's Miyazaki-san's pet. But I don't want to miss such a rare opportunity today. Miyazaki-san, could you spar with me and give me some pointers on martial arts?"

Miyazaki Yu smiled slightly: "Of course, but even a stronger martial artist with a deeper cultivation level than a person would need some time to find the loophole in someone's cultivation. This is because the loophole in cultivation is not the same as the flaw in the attack pattern. The former is much more difficult to find than the latter."

Sera Masumi's eyes lit up; these words were indeed insightful.

The weaknesses in an attack pattern are something no martial artist can avoid. So-called combat is actually an action of constantly looking for the opponent's weaknesses while concealing one's own.

Therefore, it is normal to find the opponent's weakness once you start fighting, but it is difficult to find the flaw in their cultivation.

It's like taking an exam. When someone submits a test paper, you can immediately find the questions they got wrong by comparing it to the standard answers.

However, if you want to understand the other party's knowledge system based on just a few wrong questions, and then systematically find the shortcomings in the other party's knowledge system.

That's way too difficult!

What Miyazaki Yu casually mentioned was precisely this kind of difficult task, which naturally surprised Sera Masumi.

The children were all eager to watch the excitement and didn't mind making things worse.

"Great! I'm so lucky to be able to see a swordsman fighting a high school girl!"

"Yeah, yeah, a battle of this level usually requires a ticket!"

Xiao Ai rolled her eyes at them: "You guys, you can't stir up trouble like this. Children should act like children!"

Seeing their serious and earnest expressions, the three idiots of Teitan couldn't help but swallow hard.

They all nodded silently and said, "We understand. Ai looks so scary when she's angry."

At this moment, Miyazaki Yu slowly stepped forward, while Sera Masumi had already assumed a fighting stance. Facing a strong opponent of this level, even the slightest slackness would be a great disrespect.

The other party can be relaxed and at ease because they have an overwhelming advantage, but if I were to be relaxed and at ease myself, I would be ungrateful.

"Your stance is not bad. Attack me then, and let me see just how far you've come."

At this point, Sera Masumi no longer hesitated and launched a powerful punch, her movements incredibly fierce and swift, especially her speed.

Miyazaki Yu nodded inwardly: "Her basic skills are very solid. In terms of strength, she is indeed a notch above the original Ran. Akai Shuichi has taught this little sister everything he knows."

However, even Shuichi Akai is nothing but an ant in front of me, let alone his sister.

He extended a finger, blocking Sera Masumi's fist. This originally swift and fierce attack was completely halted at a distance of about a foot in front of Miyazaki Hayao.

"How could that be? You could block my attack with just one finger!"

Seeing the shock in her eyes, Miyazaki Yu's lips curled slightly. He really knew how to put on an act.

These detectives are the most likely to cause trouble. Now that we have a chance to clash, let's show her the enormous gap between us!

"Don't stop attacking, keep attacking with all your might, let me see your moves and attack patterns so I can find your weaknesses."

Sera gritted his teeth and immediately stopped holding back, throwing punches with all his might, unleashing his Jeet Kune Do to the fullest extent. Instantly, a large number of fist shadows spread towards Miyazaki Hajime.

The people around also stared wide-eyed.

"Sera-neechan's strength is really impressive; her speed is dazzling," Genta couldn't help but exclaim.

Mitsuhiko said in a deep voice, "Miyazaki-nii is the truly terrifying one. Sera-neechan's punches are no simple matter, but he neutralized them all with a single finger. I really want to know where his limit is."

Just then, Sera let out a muffled groan, her arm went limp, and when she came to her senses, the other person's fingers were already pointing at her throat.

Chapter 383 Results of Cultivation Research

"I lost!"

Sera Masumi's face was now covered with a fine layer of sweat; the battle had only lasted a few minutes.

And she was the one launching the attacks, while Miyazaki Yu was only using one finger to defend herself. However, her physical exertion was enormous, almost equivalent to running two kilometers.

The only person present who could clearly see that moment was herself. Just now, Miyazaki Yu had been blocking her fists, and the other party's fingers poked and pointed, as if they had solidified into a wall made of fingers.

It's completely impenetrable and indestructible, like a curtain woven from rubber.

The opponent only defended and did not attack, just to observe her punching style. After observing it clearly, the opponent only made one move, his finger slightly turning and tapping her elbow.

In that instant, she felt as if she had been electrocuted in her arm, and half of her body was completely powerless.

By the time she came to her senses, the other person's fingers were already on her neck.

"The essence of Jeet Kune Do lies in the word 'intercept,' which is to block the opponent's attack. It is the most free martial art. To intercept the opponent's attack, two things are needed: if you can, strike first; if you can't, then strike back. Although your attack is swift, there are still many flaws in the connection between attacks."

In particular, your attacks seem to be divided into several segments, just like when you are practicing, some moves that should be continuous are deliberately divided into several segments.

Just like when you're reading and punctuating, if you always read according to the existing punctuation methods instead of following your own pace, you'll ultimately fall behind. It seems you need to change your practice methods.

"this,,,"

Sera Masumi couldn't help but widen her eyes, her inner shock was unparalleled.

She learned Jeet Kune Do from her various Akai Shuichis. Back then, Akai Shuichi would record his Jeet Kune Do practice movements into videos and mail them to her so she could practice according to the videos.

She did indeed practice according to the instructions and never felt there was any problem.

But she never expected that someone could find her weakness in just one brief exchange, and even deduce that there was an abnormal interruption during her practice!

This was unavoidable for Shuichi Akai, who was recording the videos. After all, the length of each video, like online classes, is ultimately not as good as teaching by example.

That's why this slight inconsistency remains in her Jeet Kune Do.

But unexpectedly, this was all discovered!

Sera Masumi never imagined that there were people in this world who were prescient and could know such secret things.

Otherwise, discovering this point would not have been so simple. At the very least, Miyazaki Yu would have needed to think it over carefully and dissect her moves in the mental world before arriving at this conclusion.

"This is truly amazing! Miyazaki-san's skill is absolutely breathtaking. Please, you must give me some pointers! I beg you!"

He then gave a very standard deep bow, which made Miyazaki Yu somewhat amused. These Japanese people just love to play these fancy tricks.

However, he didn't mind, because even if Sera Masumi were a hundred times stronger, she wouldn't be a threat to him. This girl was a pretty good detective, and she might be useful in the future.

Thinking about it, she began to give instructions, and she used real combat methods to train, making the training methods even more brutal. Sera Masumi was knocked down many times in a row.

Of course, Miyazaki Hana acted with great restraint, only knocking her down without harming her in the slightest, but it still made the onlookers' hearts pound.

Sonoko grinned slightly: "Miyazaki was so scary today. Sera is a girl, after all, yet he hit her so hard."

Xiaolan shook her head: "Yuanzi, only this kind of training can help the opponent quickly correct their previous mistakes and get their attack methods back on track. Only muscle memory is a subconscious action. Xiaoyu's method is a bit cruel, but it is indeed very effective."

After today's training, Sera only needs a short period of adjustment to make a significant improvement.

Sonoko laughed and said, "I knew Miyazaki wouldn't be so cruel to girls. The tennis tournament is next week, and I want Miyazaki to be my sparring partner so I can improve my skills. That way, I can get a good ranking in the tennis tournament, and maybe I can even win a national championship like Ran."

Xiao Lan was slightly surprised, but then smiled. That was quite possible, after all, it seemed like there was nothing he couldn't do.

As the first rays of dawn shone down, Miyazaki Yu, who had been standing quietly by the window with his eyes closed, suddenly opened them. He reached out and caught a raindrop falling from the sky with his fingers.

The moment the raindrop fell, an inexplicable force instantly enveloped it, and the surface of the raindrop began to vibrate irregularly. He flicked his finger, and the raindrop instantly splashed out, slicing a leaf in the blink of an eye like a blade. The break in the leaf was as neat as if it had been cut by a thin razor blade.

"Indeed, the potential of mental power is enormous, far surpassing that of internal force."

As a form of bioelectricity, internal energy naturally has an upper limit. According to Kawakami Gensai, cultivating sword courage and having abundant and profound sword energy, reaching the level of being able to cut through anything, is the level of a sword saint. However, the amount of sword energy that the human body can bear also has a limit, and this limit is about three times that of the physical body.

To give an example, if you cultivate through normal means and break through to the Sword Master level around the age of thirty, you are already exceptionally talented. It's like doing academic research. You have to build a foundation and learn from what your predecessors have accumulated before you can talk about research and innovation, right?

The same applies to martial arts training. You must eventually master the knowledge of your predecessors before you can consider further innovation. And learning and accumulating knowledge requires a lot of time.

Once enough has been accumulated, the physical body begins to decline, which is a dead end for cultivators throughout history.

No matter how gifted or intelligent you are, you cannot break this natural limit!

Since the physical body has its limits, internal energy naturally also has its limits.

According to Miyazaki Yu's research, internal energy is actually bioenergy. Cultivators accumulate internal energy during cultivation and can store it. When the physical body weakens, this stored energy can nourish the body and slow down aging.

But it's like a car's generator. The life force is the gasoline, the electricity generated by the car's generator is the internal force, and the energy source of the internal force is the gasoline. So the electricity you generate can never offset the consumption of gasoline.

If this works, then perpetual motion machines will emerge.

It's like that famous joke: smoking a cigarette reduces your lifespan by five seconds, while laughing adds ten minutes. So if you keep laughing, you can smoke indefinitely. Isn't that a joke?

Moreover, since bioelectricity is generated within the physical body, its quality and quantity can vary drastically due to differences in the strength of the body, the structure and density of muscles, and the way meridians operate.
