Science Fiction: Starting from Obtaining Sophon

However, once the Water Breathing technique is mastered to a high level, its power is undeniable. It is definitely not weaker than the other four basic breathing techniques, and its ability to sustain combat is even the strongest among the five basic breathing techniques!

The orderly cycle and endless renewal—that's the mystery of water's breath!

In Demon Slayer, Tanjiro's ability to later learn Sun Breathing was actually closely related to the solid foundation he laid with Water Breathing.

"Kiss kisses————"

As the lungs pump, a powerful surge of oxygen, along with the contraction of the lung lobes and alveoli, as well as the blood and muscles throughout the body, begins to flow throughout the entire body.

All the cells in the body seemed to have transformed from parched to plump, as if they had received timely rain after a long drought, or like desert plants that had absorbed water.

At this moment, Tomoko was shocked to see Gendagawa completely absorbed in his cultivation.

"I really didn't expect him to reach this level so quickly!"

Although it was a technique she deduced, she knew that it was definitely not something that an ordinary person could easily master, even if there was an analytical version.

It's easier said than done; you'll never know how difficult something is until you actually do it.

The same textbooks, the same teachers, and the same students can result in vastly different grades. Any analysis or explanation is merely an external aid.

What truly matters is always the person themselves!

"I understand now, I know what breathing techniques are!"

By feeling the flow of air between his lungs and the pathways of his body, Genda River truly understood the essence of breathing techniques.

Van Gogh once painted a starry night, in which the starry sky is depicted as countless vibrating strings. In physics, there is also string theory, which believes that the universe is composed of countless tiny strings.

The essence of life is the same; it is a dynamic outcome.

The reason why breathing techniques can increase strength is that they utilize airflow and oxygen to create the strong winds that drive windmills and the flowing water that powers waterwheels!

By making windmills and waterwheels spin rapidly, they can generate greater power!

The five levels of breathing techniques then become clear.

First is total concentration breathing, which is the foundation of all breathing techniques. Once you learn it, you can improve your body's strength in a short period of time. To use a waterwheel analogy, it means you can use your breath to start turning the waterwheel.

The moment the waterwheel turns is the burst of energy, which can generate tremendous power.

Then comes the second level, constant focused breathing. Simply put, it means being able to maintain constant focused breathing at all times of the day.

In other words, the original burst skill has become a regular skill. To use a waterwheel as an analogy, this waterwheel is no longer turning occasionally, but can turn continuously, just like it is placed in the water and can turn day and night.

Compared to the first realm, this realm is equivalent to an unlimited burst of power, and the combat strength is naturally vastly different.

Then comes the third realm, which is to activate the markings. Continuing with the waterwheel analogy, this realm requires the swordsman to further unleash their power after achieving full concentration and normal breathing, with body temperature reaching a certain degree and heart rate reaching two hundred beats per minute.

Continuing with the waterwheel analogy, the waterwheel at this point is like it has started to rotate rapidly, moving a large amount of water, but this also puts a great burden on the waterwheel itself.

Next comes the fourth realm, the realm of penetrating the world. This realm is completely beyond the reach of ordinary people. It is a level of spiritual power projection or a special perception projection.

At this level, one can anticipate enemy attacks while concealing one's own, and also possesses a kind of X-ray vision ability, revealing the internal structure of the enemy's body once the user fully concentrates their attention.

It achieves a state similar to X-ray vision, which is quite similar to the Byakugan in Naruto.

The final realm, the fifth realm, can be called the realm of the Marked Ones, which is the true realm of the gods, the level that Yoriichi Tsugikuni reached.

These are the conclusions that Genda River himself summarized.

Although there is no explicit classification of different realms in Demon Slayer, as the story progresses, the different realms become clear.

When Tanjiro first emerged from the mountain, he had only reached the level of Total Concentration Breathing. It was only after learning from Kanao at the Butterfly Mansion that he reached the level of Total Concentration in its normal form. Later, during the battle in the entertainment district, he awakened his Demon Slayer Mark. And it was during his battle with Upper Moon Three Akaza that he comprehended the Transparent World.

This will help to clarify the first four stages.

The fifth realm is not explicitly stated in the original work, but it can be inferred.

Swordsmen who unlock the third realm of markings will experience a significant increase in strength, but due to excessive consumption, their lifespan will also be greatly reduced. There is no difference even among swordsmen who have reached the fourth realm of the Transparent World.

The only exception is Yoriichi Tsugikuni, the creator of the breathing technique.

At this moment, Gendagawa, who had grasped the essence of breathing techniques, understood why Yoriichi Tsugikuni was an exception. The reason was that he had reached the level of the Manjushri Mark.

Just like the transition from Full Concentration Breathing to Full Concentration Stability, the former treats Full Concentration Breathing as a powerful attack, which is unsustainable and cannot last long. However, once you reach Full Concentration Stability, you can maintain stable output.

The same applies to blemishes. To counteract the side effects of blemishes, the blemishes need to be brought to a normal level and dynamically balanced again!

Chapter Twenty-Six: The Complete Collection of Chang Zhong!

All of this sounds complicated, but at this moment, it flashed through Gendagawa's mind like lightning.

The influx of oxygen made his mind incredibly clear.

This feeling is really great.

My brain felt like it had gone through a deep sleep, reaching an unprecedented state of comfort, and I felt as if I was immersed in flowing water!

Originally, Gentagawa thought that it would take a considerable amount of time to cultivate and achieve something.

After all, even the protagonist of Demon Slayer, Tanjiro Kamado, spent a considerable amount of time learning the breathing technique and reaching the level of Total Concentration Breathing.

But to my surprise, I made rapid progress. Once the airflow generated by the breathing technique started circulating in my body, it quickly transformed from sluggish and rough into familiar, simple, and even natural, as if everything was supposed to be this way.

Exhaling and inhaling, the airflow is like a small hurricane, moving between the mouth and nose, and circulating between the internal organs.

"This feeling is truly invigorating. It's as if my entire body is enveloped in a breeze, and every pore feels like a gentle current is flowing through it, leaving me feeling completely refreshed, both inside and out."

After completing the cultivation, I felt that the energy flow inside and outside my body had completely stabilized, and I felt incredibly refreshed all over. I was reluctant to open my eyes for a long time.

"Congratulations, host! According to the deduced information, you have now fully mastered Water Breathing and have cultivated it to the level of Total Concentration Breathing. Congratulations!"

"Have you mastered total concentration breathing?"

Genda was also surprised. The cultivation process had gone incredibly smoothly, as if it were a matter of course, so smoothly that even he felt it was unreal.

But unexpectedly, he directly mastered total concentration breathing!

Although this is only the first of the five realms, it is actually a very big threshold. Whether one has the talent to become a swordsman often depends on this step.

Tanjiro Kamado trained for a year and a half to reach this level, but he achieved it on his first attempt.

Tomoko continued, "However, that's not all the surprise. Although the host has mastered Total Concentration Breathing, in reality, his combat power hasn't undergone a dramatic change."

Genda Gawa knew this too. Before mastering the breathing technique, he was just an ordinary person. Now, even though he had mastered the breathing technique, he had not practiced it for long enough.

The benefits of this breathing technique, such as improved physical condition, speed, and recovery ability, take time to gradually become apparent.

This is similar to how a breathing technique is a top-grade elixir. After consuming it, it can increase various attributes throughout the body. However, it takes time for the elixir to be fully absorbed and for the full effects of this top-grade elixir to be realized.

"But what if the breathing technique reaches an even higher level, such as total concentration?"

"The whole concentration in the middle?"

He immediately understood what Zhizi meant. Just like the waterwheel analogy mentioned earlier, the whole collection is a waterwheel that turns occasionally, while the constant part of the whole collection is a waterwheel that turns continuously.

If we could go even further and keep our bodies in a state of full concentration 24 hours a day, it would be like exercising every moment, and the effect would be truly amazing!

Zhizi didn't keep them in suspense; she revealed the answer directly:

"Just now, when you were immersed in cultivation, you actually reached the level of the ordinary state. However, compared to the level of your breathing technique, your body is too weak. Therefore, your body is resisting, and your weak muscles will cause irregular rhythms and spasms, which will frequently interrupt the state of the ordinary state."

"But I can use electrical stimulation to counteract these rhythms and spasms, and even allow you to maintain a state of full concentration while you sleep. Isn't that amazing?"

This was certainly a surprise, a huge surprise. If Tomoko were in a physical form at this moment, Genda would definitely pick her up, kiss her a few times, and spin her around a few times.

This isn't a Tomoko, this is a cheat code!

In that case, wouldn't I have reached the second major level of breathing techniques right after I started practicing? Even Yoriichi Tsugikuni couldn't match that efficiency!

From now on, please don't call me Genda River anymore, call me Kakei!

After calming down a bit, I started to try it out. I focused all my energy on releasing my breath and held it for a while. Suddenly, my internal organs felt a spasm, and my breath almost stopped.

At that moment, countless tiny arcs of electricity surged into his organs, instantly neutralizing the spasms and restoring his breathing to normal.

In this way, Genda River tried his best to maintain his breath, and after an hour, he finally became so skilled that he could maintain a state of full concentration without having to consciously try to do so.

As long as the breath of water weakens even slightly, the breath can begin to circulate again after just one thought.

In this way, leaving the rest to Zhizi will be more than enough.

After he actually did it, Genda River's excitement finally subsided, and he felt a great hunger and exhaustion.

While it's good to have smooth cultivation, the energy consumption is simply too great.

The water that powers the waterwheel ultimately comes from people themselves.

So they immediately took out the stored food from the refrigerator and began to feast.

It has to be said that, as a homebody, the original owner's ability to store food was truly impressive.

The brand-name four-door refrigerator was filled with all kinds of fast food, including high-end instant noodles, hamburgers that only need to be heated in the oven, fried chicken that only needs to be heated in the oven, and crispy pork ribs that only need to be heated in the oven...

They offer a wide variety of products, all from reputable brands, ensuring quality.

After trying it a few times in the past two weeks, I couldn't help but use the commission I earned as a detective to buy the same brand of semi-finished fast food and replenish the refrigerator.

There is also one more thing to mention, which is the situation when I cooked for Ran and Kogoro Mouri.

You can tell from the appearance of the dishes that his cooking skills are really average, but the taste is surprisingly good. The reason for this contrast is because of Zhizi's help.
