Mastery of All Breathing Style Schools

Bai Cangshu stood at the center. Urokodaki Sakonji, Jigoro Kuwajima, and Shinjuro Rengoku—three former Hashira-level Swordsmen—had been specially invited to Kyoto because they worried that their disciples had not fully mastered the Breathing Styles they had taught.

At this moment, the setting sun stained half the sky red. These three instructors, who had mastered Water Breathing, Thunder Breathing, and Flame Breathing, joined Himejima Gyomei and Shinazugawa Sanemi in surrounding Bai Cangshu from five corners of the courtyard.

The five of them had mastered the foundational schools of the five major Breathing Styles.

Water, Thunder, Flame, Stone, and Wind—these were the five fundamental Breathing Styles derived from the now-lost Sun Breathing. Others, such as Kocho Kanae’s Flower Breathing, were Breathing Styles further derived from Water Breathing.

"Mr. Mercenary Tao, although we already know that your martial arts foundation is formidable and that you can fight an Upper Rank Demon Moon, every Breathing Style places different physical demands on each individual."

"Forcibly learning a Breathing Style unsuited to you may cause damage to your heart and lungs."

Urokodaki Sakonji made one final attempt to dissuade Bai Cangshu. He had never seen such a mad request. Even Himejima Gyomei, with his astonishing physique, had only practiced and mastered Stone Breathing, the hardest style to master.

But Bai Cangshu remained unmoved. Urokodaki Sakonji and Jigoro Kuwajima exchanged a helpless glance. Since the other party could offer that Breathing Style said to slay demons with the flesh alone in exchange, they had no reason to refuse.

The next moment, Urokodaki Sakonji’s breathing through his nose and mouth became long and continuous. His body softened as well, and he began to demonstrate the sword techniques of Water Breathing, move by move.

Bai Cangshu watched Urokodaki Sakonji’s movements. He had already entered the realm of the Transparent World. Under such circumstances, the contraction of the other man’s lungs and the movement of his muscles could not be concealed at all.

Combined with Bai Cangshu’s own ability to control his muscles almost perfectly, he could master this Breathing Style after seeing it once.

Next, every Hashira-level Swordsman and instructor took turns displaying the Breathing Style of their own school.

The gentleness of Water Breathing, the explosive force of Flame Breathing, the swiftness of Thunder Breathing, the wildness of Wind Breathing, and the iron-hard solidity of Stone Breathing.

Bai Cangshu realized that every Breathing Style was essentially a deliberate method of mobilizing one’s body, exerting force in coordination with the movements of one’s sword forms.

From that perspective, purely in terms of Breathing Styles, these schools were actually a level below Hamon.

These Breathing Styles still relied on controlling one’s breath and regulating it to alter blood flow, oxygen concentration, and the like, thereby enhancing certain aspects of one’s physical capabilities.

Hamon, however, went a step further and could genuinely produce an energy called Ripple. Besides improving one’s constitution, that energy could effectively destroy dark creatures that feared sunlight, heal wounds, and prolong life.

Demon Slayer Breathing Styles were more like BUFF-type abilities that enhanced the user’s body.

Just as Urokodaki Sakonji was about to begin a second demonstration, Bai Cangshu waved his hand.

"Alright, I understand now."

Jigoro Kuwajima’s eyelid twitched. Among the various Breathing Styles, aside from the most difficult Stone Breathing, Thunder Breathing was the hardest to find an inheritor for. This man before him was being rather boastful, and it displeased him.

But Bai Cangshu took a deep breath, and the rhythm of his breathing through his nose and mouth swiftly changed. The next moment, he moved with the gentle fluidity of flowing water, his posture flowing naturally. Was that not Water Breathing?

His breathing rhythm changed again. He took a step forward, erupting like blazing fire, his figure violent and fierce as flames.

Bai Cangshu exhaled softly, then his body paused. The next moment—

RIP!

Power exploded beneath his feet in an instant. The force of his entire body burst forth from his feet, making him so fast that his friction with the air produced a thunderous howl.

Was that not the true essence of Thunder Breathing—Thunderclap and Flash?!

By the time Bai Cangshu had fully tried each of these Breathing Styles once, everyone present, including Kocho Kanae watching from the outskirts, was too shocked for words.

They also noticed that this "Mercenary Tao" seemed to have no need to catch his breath at all while moving. Clearly, he had already entered the state of Total Concentration: Constant.

You have mastered the abilities Water Breathing (D), Thunder Breathing (D), Stone Breathing (D), Wind Breathing (D), and Flame Breathing (D) through a special method.

The abilities have now been consolidated into Breathing Style (D+): Through unique breathing, controls blood oxygen and muscles to unleash physical capabilities beyond the body's limits.

Unlike the Niko Style techniques Bai Cangshu had learned from Clown Evans, perhaps because he was in a mission world and had interacted with Plot Characters, the space had consolidated these Breathing Styles into a single ability for Bai Cangshu.

Bai Cangshu then began explaining the breathing rhythm and lung control of Hamon to everyone. Since his right hand was shattered at the moment, he could not use Hamon, much less directly use the transmission of Ripple to let them understand how Hamon worked.

He could only rely on his control over his own body to describe the breathing rhythms and the contractions of the muscles and internal organs when using Hamon.

Although everyone found it obscure, every Hashira-level Swordsman was, after all, an expert who had practiced Breathing Styles for years, and they were able to grasp a few of its key principles.

By nightfall, everyone had memorized the essentials.

While the others were still studying, Bai Cangshu slipped away alone to a courtyard.

Proceed with the settlement of Main Mission 3?

"Yes."

Settling...

Current power comparison between the Demon Slayer Corps faction and Muzan's faction: 72 VS 28

Main Mission 3 complete. Completion rating: A

Although Bai Cangshu knew that if he continued waiting in this world, given Muzan’s temperament, there was a high chance that he would not dare come out to seek revenge, and the Main Mission’s progress could continue to rise.

But Bai Cangshu did not care about that meager evaluation reward. He had more important matters to attend to. No one could steal his things and run away.

All Main Missions complete. Leave this world?

"Yes."

Bai Cangshu’s figure slowly began to fade. At that moment, the Professor’s voice came from in front of him.

"You can hold multiple cards at once, but only one card from the same sequence can be activated."

Bai Cangshu saw the other man reveal himself. The Professor wore a cloak that blended completely into the surroundings, an item that fully concealed both his form and presence.

The Invisibility Cloak from Harry Potter?

The corner of Bai Cangshu’s mouth curled up. So this was a newcomer favored by a major faction. He really did have quite a few good things.

The Professor felt a surge of panic under Bai Cangshu’s gaze. Before he could speak, the other man had completely vanished.

He also breathed a sigh of relief. This "Mercenary Tao" truly gave off an aura that made people fear him at every moment.

The Professor had a premonition that this fellow would soon stir up a storm in the space and make a name for himself.

That was why he had deliberately sought to befriend him.

"Fully repair my body. Deduct all points from me!"

Bai Cangshu shouted into the dark space, uttering meaningless words that only he himself could hear.
