Demon Slayer becomes stronger by swinging his sword

Feng Yu and Xiao Hei soon returned to the Narrow Fog Mountain

, and Nanako and the others saw Feng Yu coming back, and just wanted to go up to say hello, but as soon as they saw the anxiety on their faces, they hid to the side to practice swordsmanship.

Feng Yu glanced at Nanako lightly, and saw her efforts through the transparent world, at this time, Nanako's foundation had been laid, and it was time to make a choice to practice breathing.

"I'm back, Master Scales!" "

Wind Feather opened the door of the wooden house, and it was Tomioka Yoshiyu and Scales Left Nearji.

Tomioka was still as silent as ever, just nodding at him.

Scaly Zuo recently spoke, "It seems that something happened when I came back to see you this time?"

Feng Yu nodded, and then sat down across from them and explained to them what had happened.

"I see, no wonder you left in a hurry this time..."

Zhu Shi..."

Scales muttered as he near-seconded.

"Master Nanako, my training has reached a certain level, it's time for her to choose the breathing method..."Nanako

nodded recently, expressing her approval, after all, Nanako is greatly improving her strength every day because of the myelin washing pill, and the original training is no longer suitable for her.

"I was planning, after all, she was your disciple, and it was up to you to teach her how to use

the breathing method!!" "Well, then let her choose which breathing method she chooses!" Feng

Yu picked up a bowl of tea and drank it with a grunt, while also looking at Tomioka Yoshiyong on the side.

Feng Yu was surprised to find that the aura on Tomioka Yoshiyong's body at this time was like an ordinary person on weekdays, and it was obvious that the realm of the transparent world had been mastered by him.

"It seems that the Cleansing Pill and the Healing Pill are not in vain..."Feng

Yu said.

"Next, in addition to Nanako's breathing training, there is also something about Mixiu... I don't know what happened to her..."

Butterfly House has

been taking care of Chanel as carefully since Butterfly Shinobu brought Mihide back to Butterfly House.

At the same time, everyone in the butterfly house also became very interested in the girl brought back by the butterfly ninja.

Because Mi-su was stunned as soon as she came back, as if she were a statue, through the butterfly ninja, they also knew what Mi-so had experienced.

I couldn't help but sympathize with Meixiu in my heart, and at the same time, I was more concerned about taking care of her.

It's just that everyone took turns to take care of Meixiu, but they didn't notice that Chanel on the side was watching her deeply.

Every time after everyone left, Chanel would always stay by Meixiu's side and pull her outside to the sea of flowers planted by everyone in the butterfly house.

Stretching out and attracting butterflies in the sky surrounded the two of them.

It's just that Meixiu's expression hasn't changed, and she lets the butterflies fly.

Suddenly

, a pink butterfly landed on Mi-so's nose, and two tentacles gently touched Mi-so's cheek, as if to convey a message.

Then, Meixiu's face began to turn painful, her eyes kept flowing with tears, and her mouth kept shouting: "Father... Mother..."

Mi-su fell to the ground, constantly curling up her body

, and everyone rushed

forward to check what was going on, only to see the butterflies in the sky surrounding Mi-so, forming a protective circle, as if to protect her from being harmed.

Everyone wanted to step forward, but the butterfly seemed to have a mind of its own and did not let anyone else approach.

At this time, Butterfly Shinobu also rushed over, and she slowly approached Meixiu, but surprisingly, the butterfly did not hinder Butterfly Shinobu from stepping forward.

Butterfly Shinobu gently picked up Meixiu, and the butterfly Shinobu next to him also followed Butterfly Shinobi, and it can even be said that she followed Meixiu.

Butterfly Shinobu took out a needle from her arms and hit Mihide's arm,

and soon

Mihide slowly regained her composure and fell asleep.

Everyone was relieved to see that Meixiu had quieted down, after all, it was obviously very painful to see the appearance of Meixiu just now.

Butterfly Shinobu hugged the sleeping Mi-so, walked back to the room step by step, and nodded at Chanel as she passed by.

After returning to the room, Butterfly Shinobu was surprised to find that there was a pink butterfly that had been following them all, and then landed on Mixiu's face under the surprised gaze of everyone.

The two tentacles kept caressing Mixiu's face.

"Shinobi-sama, what is this?" asked

the three little ones of the butterfly house.

"It's okay, it seems that this butterfly also cares about Keling's beauty..."Butterfly

Shinobu said quietly looking at the pink butterfly.

"Looks like she'll probably be back to normal when she wakes up,"

Butterfly muttered.

"Okay, I'll take care of Meixiu next, and you guys will take care of the other patients in the butterfly house.

Butterfly Shinobu motioned for everyone to leave here

, everyone nodded, and soon left, only Chanel was still standing in place.

"This kid has closed himself..."Butterfly

Shinobu gently wiped her cheeks for

Mixiu, "This kid is very similar to you

, Chanel..." Butterfly Shinobu smiled slightly, Chanel's face on the side did not change, but he came to the side of the bed and put Mixiu's hand in his palm.

"Sometimes it's a good thing not to wake up..."
