The Heavens: One World, One Superpower

Urokodaki Sakonji said, "Although you can absorb the power of the sun and make it your own, I can see that this is a passive process. At this stage, you should still focus on practicing swordsmanship."

Su Chen said, "Please rest assured, I will not neglect the training of breathing techniques and swordsmanship. Only by mastering breathing techniques and swordsmanship can one's combat strength be improved rapidly."

"It's good that you understand this principle." Urokodaki Sakonji looked at Tanjiro and said, "Only the three of us know about this. We can't reveal a single word to anyone else."

Tanjiro nodded.

A storm raged within him.

It is simply unbelievable that a person could wield the power of the sun.

This situation must be extremely rare.

"Mr. Linlong, Brother Chen, don't worry, I will absolutely not tell anyone what I saw today."

He had a vague feeling that...

When the power of the sun appeared, there was a flow of energy circulating within his body.

It seems to be a power hidden within the body.

Determined to get close to Su Chen and borrow his solar power, he could unleash the power within his own body and improve his strength more quickly.

Urokodaki Sakonji breathed a sigh of relief.

Su Chen continued his cultivation.

Let the sunlight shine down.

Allow the power of the sun to enter your body and enhance your physique.

He had a guess.

Being able to harness the power of the sun is just the beginning.

More and more surprises are coming.

It's not just about physical improvement; it might also grant the mastery of many unimaginable supernatural abilities.

Su Chen focused his attention on practicing breathing techniques and swordsmanship.

He thought to himself, "I've taken the first basic step to becoming a swordsman; now it's time to start the second step."

"The first step is to improve physical fitness, reaction speed, and willpower."

"The second step is to build on this foundation and accelerate the practice of water breathing and sword techniques."

"Based on my understanding of the Demon Slayer storyline, there are five levels of breathing techniques: Full Concentration Breathing, Full Concentration - Constant Concentration, Demon Slayer Mark, Transparent World, and Crimson Blade. Right now, I can only achieve Full Concentration Breathing, not Full Concentration - Constant Concentration."

Su Chen knew this clearly.

Concentrated breathing is a breathing technique used intentionally during combat to enhance physical fitness, speed, strength, and recovery.

This is only the level of an ordinary team member or a newcomer.

The requirements for the complete set of regular courses are very high.

This is the threshold for becoming a pillar.

It requires continuous breathing 24 hours a day, and it operates automatically even when sleeping or relaxing.

This situation requires physical strength and endurance far exceeding that of ordinary people.

Only in this way can we continuously interact with the energy of heaven and earth.

To maintain a swordsman's peak condition for decades.

However, achieving full concentration and constant concentration is not easy.

Su Chen pondered to himself, "Mr. Urokodaki said that to solidify Total Concentration Breathing into an instinct, and transform it into Total Concentration Breathing in its normal state, it would probably take 1 to 3 months. During this period, one should reduce deliberate effort, moving from forceful maintenance to natural holding, so that it can be sustained without distraction. And integrate it into all actions: eating, bathing, talking, sleeping, with breathing always on. Finally, one must conduct an extreme test: continuous breathing for 24 hours without interruption, even when sick, tired, or not sleeping. After trying it many times, one can gradually form a state of constant concentration."

"The first and third ones weren't too difficult for me, but the second one, which I had to integrate into all the movements, was a bit challenging."

"However, these can all be achieved through practice."

"The best practice is sword practice. As long as you can concentrate your breathing during intense sword practice, then other times won't be a problem."

Su Chen's greatest advantage is his incredibly strong physique.

It has already surpassed the average person by more than five times.

And it continues to grow stronger.

This makes one naturally suited to practicing breathing techniques.

He then thought of his swordsmanship practice.

He has not yet entered the "man and sword as one" state that Urokodaki Sakonji spoke of.

"What exactly is the state of being one with the sword?"

"Could it be similar to the concepts in the martial arts novels I read in my previous life?"

He thought of the martial arts novels he had read in his previous life.

It mentions four levels of sword practice.

It contains the philosophy of life.

They are respectively: having a sword in hand but no sword in mind, having a sword in hand but having a sword in mind, having no sword in hand but having a sword in mind, having no sword in hand but having no sword in mind.

Having a sword in hand but not in mind: having a sword in hand but not understanding its meaning or inner workings, resulting in stiff movements, a disconnect between the sword and the user, and merely having the form but not the spirit.

At this point, it has form but no spirit, is merely a facade, and relies on form.

With a sword in hand and a sword in heart: man and sword become one, the sword moves with the heart, the moves are made from the heart, the sword is man and man is sword, power and spirit are completely integrated.

At this moment, man and sword become one, knowledge and action become one, and skill reaches perfection.

No sword in hand, but sword in heart: not clinging to the sword, everything can be a sword, a falling leaf or a flying flower, bare hands can all hurt people, the sword intent is hidden in the heart and transforms into nothingness.

At this point, the best strategy is to have no strategy at all; it is internalized and one returns to simplicity.

Having no sword in hand and no sword in heart: letting go of attachments, embracing all things, not killing, not fighting, not clinging—this is the ultimate state of "peace" and "great freedom."

"Perhaps what Mr. Urokodaki was referring to was the second level of swordsmanship."

"No matter what, if I practice swordsmanship ten thousand times until the sword moves at will and the moves are executed from the heart, then perhaps I can reach the state of oneness with the sword."

Su Chen understood what he needed to do at this stage.

He immediately threw himself into the experiment of practicing swordsmanship ten thousand times.

And throughout this process, maintain a state of complete concentration while breathing.

He believed that as long as he practiced swordsmanship ten thousand times and maintained full concentration in his breathing, he could succeed.

He will then be able to complete the second step of his cultivation.

And so, Tanjiro saw the sunrise every day.

Su Chen was already practicing his swordsmanship in the courtyard, carrying a Nichirin Blade.

The blade drew out a surging curtain of blue water.

Dazzling and captivating.

But hidden within the dazzling and enchanting water curtain lies a deadly trap.

From the first light of dawn until the sun sets in the west.

During this time, Su Chen would only take short breaks for necessary things such as eating and drinking.

He spends the rest of his time practicing swordsmanship.

Tanjiro was terrified watching this intense sword training.

He couldn't understand how Su Chen's body could withstand it.

Prolonged and intense muscle stretching can lead to muscle strain.

It is extremely harmful to the body.

Even Urokodaki Sakonji was astonished.

He had never seen a swordsman who dared to exert his full breathing and unleash sword-shaped power for more than ten consecutive hours.

This behavior is tantamount to destroying one's own body.

Use your body to continuously unleash the energy of heaven and earth.

Only the heavens and earth can perform such an operation.

He was originally very worried about Su Chen's health.

But after some investigation, it was discovered that Su Chen's physique was still healthy and strong, and his physical fitness was even improving faster, as if he had been on a roller coaster.

His heart, which had been clenched with anxiety, finally settled down.

Su Chen himself was not worried at all.

Because it has the ability to absorb solar energy and restore itself.

He even believed that this level of training was far from reaching the limits that his physique could withstand.

Nevertheless, his physical condition was improving rapidly.

It's a much faster way to improve than simply absorbing the sun's power.
