Demon Slayer becomes stronger by swinging his sword

After the worship, Feng Yu led Mihide back the same way.

The two of them were silent all the way, and Meixiu sat on Xiao Hei's back with a sad face looking at the scenery that kept flying upside down below.

Feng Yu looked into the distance, with a lot of thoughts in his heart.

Another night had passed

, and by the time the two of them returned to the Narrow Misty Mountains, the eastern sky had turned white, and rays of sunlight were shining on the entire land.

"I promised you!" Feng

Yu said with a sigh as he looked at Mixiu.

Mixiu's face showed a hint of surprise, and just as she wanted to say something, she heard Feng Yu say, "But you can only go out with me when you go on a mission in the future!"

Mixiu's face showed a happy expression, although she didn't expect Feng Yu to restrict her freedom, but as long as she can become as strong as Nanako, and then avenge her parents, then everything will not be a problem.

"I understand!" shouted

Mi-so, her face swept away from the previous haze, and her face was radiant.

Feng Yu felt that his Heavenly Spirit Gai was a little painful, and couldn't help but press his fingers to soothe himself.

"Alright, since the matter has been decided, then we have to do it with all our might..."

, Scales pushed open the door of the wooden house and said to the two of them.

They both nodded at the same time, and then followed into the cabin.

Soon, Nanako also entered the wooden house, and after eating together, Feng Yu also asked Meixiu to take the Cleansing Pill to refine the foundation as she did with Nanako before.

Later, the scale of the left to take care of Mixiu, and he continued to teach Nanako the breathing moves of water.

"The action is too dry... There is no softness of water that has changed..."

Wind Feather commented on Nanako's movements and the frequency of her breathing as she cast her water breath.

"The breath of water is about imagining yourself as water, comprehending the flow of water, the diversity of water..."

At the same time, Tanjiro's figure appeared in his mind

, "Do you want to train Nanako like Tanjiro..."

Feng Yu couldn't help touching his chin, and Nanako, who was practicing with his heart, suddenly felt a chill.

The same is true of Tanjiro, who is far away, and suddenly a chill wells up in his heart.

"Haqiu!" Tanjiro

couldn't help but sneeze, and the yellow-haired young master next to him was directly frightened by Tanjiro's sudden sneeze.

"Ahhh

"Charcoal ~ Zhi ~ Lang ~ "

Shanyi's face was pale, obviously frightened.

"Okay, Shanyi, I'm going to the east, are you so scared to come with me, I'll protect you!"

Tanjiro smiled innocently.

"Da ba! I don't want to go to such a dangerous place, I'm going to die, Tanjiro, I'm going to die! I'd better hurry up and find a girl to be my wife!"

At this moment, suddenly a girl's voice reached Shanyi's ears.

"Ahh

"Don't, you go away!"

the girl slapped Shanyi's face, and the red palm print soon appeared on his face.

After pushing Shanyi away hard, he walked away angrily, scolding as he walked.

Tanjiro reluctantly walked over and picked up Zenitsu, who was sitting on the ground sadly, and began to comfort him.

On the other side

, Feng Yu really couldn't stand the kind of uncoordinated and hard movements that Nanako trained, so he took Nanako to the old place.

Looking

at this waterfall, Feng Yu couldn't help but sigh that this waterfall is really an old-timer, witnessing the process of generations of water breath masters from weak to strong.

"Master... What are we doing here..."

Nanako looked at the splashing water, and couldn't help but get nervous in her heart, and asked cautiously.

"We must be here for training..."

A smile appeared on Feng Yu's face, but this smile made Nanako feel a little scared, and she took a few steps back.

"What are you going to retreat, hurry up, do you see that stone? That's your Uncle Tanjiro's throne, and his water breath can be practiced to that extent because he sits on that stone every day to train. "

Look at the moss on the top of the stone, it's all Tanjiro wiped it clean for you!" said

Feng Yu with a blushing face and a heartbeat.

Nanako swallowed her throat and said tremblingly, "Master, have you ever sat on that stone before?"

"Of course... I want to back then..."

Feng Yu just wanted to say something, but suddenly reacted and said with a dark face

, "So when do you want to wait until you go up?"

"Ahaha, go now!"

Nanako didn't dare to stay long, and quickly jumped onto the stone.

As soon as he reached the top of the stone, the cold water washed over his body.

Nanako didn't stand still, and was directly washed into the pool by the current.

"Purr!"

Nanako took several sips of water before struggling to surface.

Then he pitifully threw a distressed look at Feng Yu for help.

"If you can't endure this little hardship, then don't even think about avenging your mother!" Feng

Yu said with a serious face.

Nanako also knew that this was not a joke, gritted her teeth, and sat on the stone against the fierce water that fell from the sky.

"I can definitely do it, I must be able to..."

Nanako cried out with her eyes closed and gritting her teeth, as if this would give her more strength.

It's just that although her small body has undergone many days of training and myelin cleansing, she soon lost her physical strength.

He was swept into a pool of water again.

This time, Nanako didn't make a sound, just silently climbed up the stone by herself, and then sat on it again.

"Adjust your breathing, remember how the water breath works, and feel the flow of water!" shouted

Wind Feather.

It's just that Nanako at this time already feels that her body has been hollowed out, without a trace of strength, tired, and weak, appearing in her mind!

"Bang la!" The

sound of the water flow covered Feng Yu's voice, even if Nanako heard Feng Yu's voice, she probably didn't have the strength to continue at this time.

Feng Yu saw Nanako, whose face was pale, and it seemed that she was about to pour it into the water at any time, but her small body was still holding on.

Feng Yu jumped onto the stone, picked up Nanako and came to the shore.

took out a healing pill and put it in Nanako's mouth.

Soon, Nanako's face began to flush, and the tiredness on her body was swept away, and she was full of vitality.

"Well done..."

Feng Yu said as he looked at Nanako.

"But... I... I was unconscious..."

Nanako lowered her head and didn't dare to look at Feng Yu's gaze.

"You're still young, your physical strength hasn't reached the best period yet, it's beyond my budget to be able to do this, I originally thought that the first time you were swept down by the current, I might have to pull you ashore, I didn't think that you would rely on your perseverance to go up again, and I was a little surprised!"

Feng Yu comforted.

"Okay, it's not too early today, let's go back first, and continue training tomorrow!"

Nanako nodded, and followed Feng Yu back to the cabin.
