The pirates sat and forgot, and they really believed the nine truths and one lie.

On the first night, most of the navy learned that Marshal Sengoku had made an exception and promoted Rengoku Kyojuro to Major at headquarters. Naturally, a swordsman who had never made any achievements suddenly became a colonel-level officer, which naturally attracted criticism from some people.

As Rengoku Kyojuro was about to contribute his family's breathing method to all the navy for free, the original dissatisfied voices disappeared instantly.

There are very few combat skills that can be learned in the navy. Ordinary people can fully master the six styles and, combined with the two-color domineering power, can stand on their own and belong to the elite level.

The navy does not have any secret manuals for learning swordsmanship, and all previous navy admirals are not good at swordsmanship. They tend to rely on fruit abilities or close combat.

Most of them are teachers like Karp, who do not treat students as human beings. They train their bodies under various extreme challenges. Most ordinary people do not have the physical talent to endure it, and in the end they can only be mediocre and serve as soldiers.

The firearms commonly equipped by the navy are not much different in generation from those of the pirates. All that is fired from the muzzles are bullets, and some of them have extremely poor accuracy, requiring the navy to stand together and fire intensively.

If an ordinary person wants to join the navy and learn some skills, he can only learn the six naval styles at most. After that, he needs to rely on his own efforts and luck to develop to a more advanced level.

The breathing method that Rengoku Kyojuro provided to the entire navy is extremely precious. The future benefits of the worst breathing method will be equal to the Navy's Six Styles.

Although experts do not like the rigidity of the Six Styles of the Navy, especially government agents, they regard the Six Styles of the Navy as the foundation of their lives.

That depends on who you compare them with. The grassroots navy and grassroots pirates are treated completely differently. The navy can use basic moves such as the Six Styles of the Navy, and it is easy to deal with pirates who have no rules.

When Marshal Sengoku learned that Rengoku Kyojuro was going to contribute his breathing technique for free, he wished he could promote him to a higher rank, as this contribution was worth at least the rank of major general.

If the breathing method could provide the navy with some third-rate swordsmen, then Rengoku Kyojuro would be treated like a treasure by the entire navy. Even if this contribution killed 100,000 pirates, it would not be as precious as the breathing method.

The first batch of students who received instruction from Rengoku Kyojuro all had some background and strength, and their military ranks were very uneven. In the early stages, talent in swordsmanship was highly valued.

"A lot of familiar faces came today, including a candidate for general and a lieutenant general who also participated in the study"!

Tashigi stood next to her superior, and both Erza and she saw Vice Admiral Gion, who was the highest-ranking navy officer in the room and also a rare swordsman among the navy.

Erza took the initiative to seize this learning opportunity, and the task of monitoring the greatsword and the exorcist was temporarily pushed to Smoker and Tina.

If one could quickly learn the breathing technique within a few days using his natural talent, he could improve his strength by 10% to 20% before the battle, which would be very important for both the navy and the individual.

Erza also saw an acquaintance, Levi, who had studied with her in the training class. He was much shorter than her and was also a ruthless man who liked to chop down giant creatures.

The bald man Bellemer is very conspicuous in the team. Although he does not use a sword, according to him, breathing techniques can be used on any weapon and are not limited to helping swordsmen.

The special training class that was temporarily opened before the war had only ten people in total. They were considered to be moderately accomplished swordsmen in the navy. This also indirectly proved that there were not many masters of swordsmanship in the navy.

After waving goodbye to the junior navy officers, Rengoku Kyojuro appeared in front of the ten cadets at last. He also took the initiative to apologize and explained the reason for his lateness. The navy officers were so enthusiastic that they pestered him with questions and there were too many of them for one person to answer them all.

He first solemnly introduced himself, then asked the ten students to introduce themselves, so that both sides could get to know each other a little, and then got to the point.

"The breathing method is not a unique inheritance in my family. Berumeba's senior brother also uses the breathing method. The techniques are the same, but the effects and properties are different. After mastering the techniques, you will find the breathing method that suits you in the process of learning." Rengoku Kyojuro did not feel proud because he learned breathing first. Everyone has equal personality.

The breathing method is just a short name. Its full name is concentrated breathing. It mainly accelerates breathing, strengthens the functions of the heart, lungs and other organs, allows the blood in the body to obtain a large amount of oxygen in a short period of time, greatly improves physical fitness in a short period of time, and obtains physical strength several times that of normal state.

As for why the breathing method can bring about attribute attacks, it is not difficult to guess. The breathing method can open up the acupoints in the body and absorb natural energy from the outside world for use in a short period of time.

Everyone has different affinity for natural energies, so there are many branches of breathing techniques. For example, Rengoku Kyojuro uses the Breathing of Flame, and Bellemere's senior brother, Beimei Gyomei, has developed the Breathing of Rock.

The strongest swordsman in the Joker Pirates, Black Mou also uses a breathing method. He uses the Breathing of the Moon, which is more advanced than the breathing method of ordinary people and is not limited to attributes.

"So everyone here doesn't necessarily learn the Breathing of Flame. You will eventually find the breathing method that suits you through trial and error. Now please watch my demonstration," Rengoku Kyojuro restrained his smile and raised his hand to signal everyone to step back a little to avoid accidental injuries.

Rengoku Kyojuro stood in the center of the field, his back straight as a pine tree. He took a deep breath, and a bellows-like breathing sound came out of his throat. The sound gradually became deep and powerful, with a burning rhythm.

Everyone only saw his chest rising and falling slightly, and the air around him seemed to vibrate and heat up. Even the strong ones could feel the change in the surrounding temperature.

The scabbard at his waist suddenly vibrated, and he grasped the hilt with his right hand like lightning, and the movement of drawing the sword was so fast that only a shadow was left.

The moment the blade left the sheath, orange-red flames suddenly burst out from the blade, climbing and burning along the blade like a living thing.

The flame on the blade burned steadily, and the flame tongues danced unsteadily in the sunlight, but did not burn the blade at all.

The flames on the blade gathered like a stream of water, forming a wave of fire that shot up into the sky. Everyone around held their breath, shocked by this astonishing scene.

They could clearly feel that the flame was not a magic trick but real, and the amazing control that Kyojuro displayed through breathing techniques allowed the swordsman who had not eaten the devil fruit to have attribute attacks.

Rengoku Kyojuro sheathed his sword, and the flame instantly went out, as if it had never appeared. The navy watching from afar exclaimed one after another. They also saw hope of becoming stronger, as long as they could learn the breathing technique!

He looked at the ten students in front of him with a bright smile on his face: "What I used just now was the Breathing of Fire. I have already shared my experience in practicing the breathing method. I have asked the Navy's copying department to make ten copies. You can ask me anytime if you have any questions."

Afterwards, the cultivation experience points were distributed to ten students. Learning the breathing method still depends on some talent. It takes a long time for ordinary people to get started, but it doesn’t take long for geniuses, as long as half a month or as short as a few days.

The navy has little time left, and the ten students must learn the breathing method as soon as possible to enhance their strength and increase their chances of survival on the battlefield.
