Demon Slayer becomes stronger by swinging his sword

None of them understood the use of Feng Yu's gift to Nanako, but judging from the serious expression on his face, the crystal necklace might not be as ordinary as it seemed on the surface.

After all, every time Feng Yu took out something in his hand, it had a magical effect.

Not to mention that it was the first time he had asked for an item so seriously.

Scales left the next time just quietly glanced at the necklace around Nanako's neck and didn't pay much attention to it, while Tanjiro on the side was familiar with the changes in his body.

"Senior Brother Kazeyu, I feel like I'm getting stronger now..."

Tanjiro said in surprise.

"Strong?" said

Feng Yu with a smile as he turned his head.

"If it's very strong, that means you can continue training today..."

Tanjiro heard this, his body couldn't help but tremble, and there was a hint of timidity in his eyes when he looked at Xiao Hei and Xiao Bai.

Tanjiro swallowed his saliva and said, "Senior Brother Kazeba, let's continue

yesterday's training!" Looking at Tanjiro's confident appearance, Kazujiro nodded, and then said to Xiaogu and Xiaobai: "You don't have to be merciful today like yesterday." "

Yes, master!" replied Hei and Bai at the same time.

Koguro's eyes were red, and he looked at Tanjiro with a strange look, as if there was a hint of empathy in his eyes.

"Then today Tanjiro is going to train with Kokuro and Kobai, remember that you are going to train all the concentrated breathing, not your reflexes. "

What you have to do is that no matter what happens, don't stop your breathing, and you have to breathe all the time!"

said Kazeha as he looked at Tanjiro and said solemnly.

"Yes, Senior Brother Kazeha!"

Tanjiro replied immediately.

The scales on the side didn't make a sound, as if waiting for Feng Yu to arrange a task for him.

"Then the next thing is Nanako,"

Feng Yu said.

"Nanako, you can follow me today, I have already made a plan for your cultivation.

Nanako nodded, then touched the necklace around her neck lovingly.

"Master Scale, if you don't have anything to do, you can supervise or punish Tanjiro, as long as you don't lose your breath, I can save you!"

Then, out of nowhere, he pulled out the wooden stick that he had punished Tanjiro yesterday.

I saw that there was still a little blood stain on the stick.

"Wind Feather... Senior brother, I'm still here..."

Tanjiro looked at the wooden stick in Feng Yu's hand, as if he had seen something very terrifying.

The body instinctively produces a trace of fear.

Scales took the wooden stick from Kazeha's hand in the near future, and then looked at Tanjiro suspiciously...

I saw that the scale of the left made yesterday's Feng Yu movement, holding a wooden stick up and down in the palm of the other hand, and at the same time looking at Tanjiro.

Tanjiro only felt that the image of the scale Takizuo Jinji suddenly turned into a wind feather, and he smiled at himself...

"Master Scales... "

Hmm,"

Scales nodded faintly.

Youdouzi, who had been behind everyone, also came over, hugged Tanjiro, and then made a thumbs up gesture with his fingers under his surprised gaze!

Tanjiro and they returned to the place where they trained yesterday, and then began a day of torture flow rapid strength growth method.

"Come on, Koguro and Koshiro-senpai!"

Tanjiro prepares to meet Koguro and Koshiro's attack.

"Quack, boy, don't hold on for three seconds like yesterday!"

said Xiao Hei with a smile.

"I feel that my strength has become stronger, Xiaohei senior, you can come here with confidence!"

"Quack, scream attack!" A

terrifying sound wave came out of Koguro's mouth, Tanjiro immediately quickly covered his ears, and the entire concentrated breathing on his body was also cut off at this moment.

"Mr. Scale, Tanjiro's full concentration is breathing, it's time for you to punish him..."

Xiao Hei said to Scale.

Scales got up the next time, and the red tengu mask made him look like a demon in Tanjiro's eyes at the moment, and the wooden stick in his hand had also become a terrifying torture tool.

"Master Scales... Can you tap it?"

Tanjiro begged for mercy.

It's just that Scales Left didn't give him a chance recently, and directly waved the wooden stick and slashed it down.

Immediately, Tanjiro clutched his stomach and fell to the ground in pain.

"Wind Feather should have told you that the effect of Concentrated Breathing, you are too susceptible now, you need to treat Concentrated Breathing as a physical instinct, and make it work all the time!"

Then Tanjiro began the next round of torture!On

the other hand, on the other hand, on the side of Feng Yu, he led Nanako to the waterfall where Tanjiro had cultivated the breath of water before.

"Alright, that's it!"

Wind Feather began.

"What a spectacular waterfall!"

Nanako exclaimed.

"Okay, your task today is relatively simple, and that is to eat this!" Feng

Yu said as he took out the Cleansing Pill and showed it in front of Nanako.

"This pill can improve the quality of your body, and strengthen your foundation by cutting the meridians

and washing the marrow!" Feng Yu put the marrow washing pill into Nanako's hand.

Nanako said hesitantly, "Master Feng Yu... This elixir works so well, it must be very precious!"

"What, everyone has to ask this question again..."Feng

Yu thought to himself.

He had already spent a million times to swing the knife to buy fifty pills, half of the marrow cleansing pill, and half of the healing pill.

Now the inside of his system backpack is still bulging.

"If you eat this, you will be able to grow faster in the days to come!"

Nanako took the pill, and for a while, she felt hot and uncomfortable!

"Master... I'm so uncomfortable..."

Nanako's face showed a pained expression, and she looked at Feng Yu for help.

"Hold back, it will pass soon!" Feng

Yu looked at her coldly.

Nanako also knew that Feng Yu would not lie to her, so she gritted her teeth and endured the discomfort and let the transformation of the Cleansing Pill.

Soon, an unpleasant smell began to fill the air.

"Ah, master, I stink

..." Nanako felt sticky and greasy all over her body, and a foul smell wafted out of her body.

"Well, go jump in the water and wash it off!" Feng

Yu nodded, then motioned for her to rinse herself.

After washing, Nanako's whole appearance is a lot more refined, the original skin is a little dull yellow, but now it is white and delicate, and the little baby fat has disappeared, leaving only the clear outline of water chestnuts.

Her body seems to have grown a little taller, from about 1.3 meters to more than 1.4 meters.

Nanako's appearance has changed a lot, but the improvement of talent is the greatest.
