The suffering of flesh and blood begins with Demon Slayer forging swords

As the weather got colder, heavy snow began to close the road....

Butterfly Shinobu and Butterfly Kanae still can't run for long periods of time, especially in winter.

Under the high degree of exercise, they constantly inhaled cold air, from their throat to their trachea to their lungs, and each breath made their chests tingle.

"The physique is so bad! If your determination is only to this extent, then don't try to learn breathing!

Ye Wen felt that these days, although the sisters' endurance has improved to a certain extent, as the weather gets colder, they need to consume more calories, which is enough to smooth out this slight improvement.

"Whew-huh-"

Only two constantly gasping voices responded to Ye Wen.

"Keep running! Squeeze out the last drop of your physical strength for me!" If you don't improve your basic physical strength, you can't use breathing for a long time! Unless you are confident that a battle will be fought in a few breaths!

Ye Wen ran in place next to Butterfly Shinobu, who had stopped and supported his knees with both hands.

"Whew-whew—, it really doesn't work!"

The butterfly couldn't help but close his eyes and gasped for air, although the air inhaled into the lungs was cold and piercing, but without panting, it was likely to faint from lack of oxygen.

The smell of rust continued in his throat, his stomach was like a river and a sea, even his voice became hoarse, and his limbs were sore and swollen.

In this state, once it stops, it is difficult to continue running.

"Shinobu, let's run a little longer, I'll pull you!"

Kanae trotted to Shinobu's side, took her left hand, dragged and continued to run forward.

"Come on, girls, adjust your breathing, adjust your running posture, everyone's running posture is different, you have to find out the movements that suit you, and drive the body with the least strength."

Ye Wen followed behind the two sisters, trotting while repeating the purpose of their running again, which was not a meaningless consumption of physical strength.

At night

, waiting for the girls to collect the ingredients and set up the camp, Ye Wen only needs to sit back and enjoy his achievements.

"Oh, is it grilled fish today! Who caught it. "

Without nets, without harpoons, it's not easy to catch fish with a sharpened branch.

"It's Shinobu, she's very good at speed and judging things!"

Every time Butterfly Shinobu made something extraordinary, Kanae would praise Ye Wen very proudly.

Kanae is unexpectedly very childish, and wants to be praised by her elders.

"Yoshi, Yosai, Shinobu is very powerful, and Kanae is also good!"

Ye Wen rubbed the heads of the two girls, after so many days of training, sweat mixed with dust had made the originally smooth black hair a little sticky.

Quietly, he put his hand to his nose and sniffed.

The taste is ok. "

So, let's continue learning the breathing method after dinner today."

"Good!"

"Good!"

As the most adaptable breathing method, water breathing was naturally the first choice that Ye Wen taught them.

And after that, Kanae and Shinobu's self-created breathing method was derived from the breath

of water, and since Ye Wen improved the breath of water that night, he would perform it every night, which not only calmed people's moods, but also prompted the sisters to enter the rhythm of breathing method faster.

[Water Breath · Pick One Type · Kai · Change]

Ye Wen can easily unfold it with a sword, and Kai, not so much a move, is more like some kind of field.

The talent of righteous courage is very strong, and this move already has the charm of penetrating the world.

In the field of Kai, Ye Wen can also be distracted and constantly teach the two sisters the main points and lessons of the breathing method.

"In my sword move, it is best for you to meditate on yourself as a lake, so that it is more convenient for you to enter the rhythm of the breath of water."

"Breathe slowly and deeply, and let the air flow around you on the tip of your nose..." Unexpectedly

, that night, Kanae learned the trick, but like beginners, she can only use breathing by being very concentrated.

As for Xiao Shinobu, he can only be in the realm of Qi, and there is a certain prototype of the breathing method.

This may also have a lot to do with personality, Butterfly Shinobu's personality and thinking are more jumpy and impatient than her sister, and these factors will not help learn to breathe in water.

The next day, Ye Wen asked the two to use the breathing method as much as possible when running, imagining that the power of the guided breathing method was transmitted to the lower body, which could greatly improve the ability of muscle recovery.

In order to let the sisters know what it is like to learn the advanced breathing method, Ye Wen performed it for them at night.

He used his dragon's teeth to cut an inch long wound on his left arm, and blood continued to flow out as if a reservoir had found a drain.

"Ah, Mr. Ye Wen, this is cut to the vein, it must be bandaged immediately."

Saying that, Kanae was about to tear a piece of fabric from her clothes and bandage Ye Wen.

Ye Wen stopped this behavior in time and asked them to take a closer look.

"Look, just like I let you use breathing to restore your strength when you run during the day, you can restore the wound at my level."

As soon as the words fell, the wound that was originally bleeding stopped, and then Ye Wen casually grabbed a handful of snow from the ground and wiped the blood stain off the wound, and only an inconspicuous scar remained in the original bleeding position, indicating that what was just now was not an illusion.

"Mr. Ye Wen, if everyone can learn such a powerful breathing method, then there will be no more diseases and injuries in the world."

Kanae carefully examined it and confirmed that the wound was basically healed, and she couldn't help but sigh.

"That being said, do you think everyone has a talent for learning breathing? Not everyone is like you, you can feel the flow of breath, in general, from a week to a month, if you do not feel it, then there is no talent.

"Besides, if someone who can breathe becomes a ghost, what do you think will happen?"

Ye Wen couldn't help but interrupt the beautiful world in Kanae's fantasy.

"It is said that there are also ghost killing team swordsmen who have turned to the ghosts, just for that eternal life, have unlimited time to delve into the mysteries of the breathing method, and under the strong resilience, they will always be at the peak, and they can unscrupulously wield their sword skills, which can be said to be a big trouble."

"That's why you want to cultivate a master, you need to test the heart of a swordsman!"

Butterfly Shinobu jumped out just in time to add.

"Not bad, not bad, Xiao Shinobu will rush to answer, when the time comes when you are qualified to participate in the final selection, I will ask someone to get you over, rest assured."

After that, after Butterfly Shinobu also learned the breathing method, Ye Wen took out two nikkami knives from his box and gave them to them, and asked them to run with them when running.

As for why there are still knives that have not been fused into the dragon's teeth, because the dragon's teeth have reached extremely high quality, and one or two nikken knives can't change much.

Coupled with the need to train the butterfly sisters, Ye Wen has not had trouble finding the members of the Ghost Killing Team for a long time, and the legend of Benkei has slowly disappeared from the field of vision of the Ghost Killing Team.
