Demon Slayer becomes stronger by swinging his sword

Feng Yu believes in the prophecy of Yaoya Yashiki, but the only thing he doesn't understand is whether Purgatory Kyojuro really can't change the fate of the original book in the end.

"Since the Sanyashiki Yaoya has already shown that Purgatory will be dangerous, then the plot of the Infinity Train may have an accident

..."Feng Yu thought of Yi Woza, the purgatory in the original book was killed by Yi Woza, and then escaped before sunrise!"

"So will the death of Purgatory still be related to Yi Woza..."Feng

Yu returned to Butterfly Dance with doubts.

"Feng Yu-kun, you're finally back!" Butterfly

Shinobu saw Feng Yu's arrival, and a smile was on his face.

Feng Yu smiled and nodded in agreement.

At this time

, "Senior Brother Feng Yu!" Feng Yu

turned his head to see that it was Tanjiro, who was standing not far away and waving to him.

At the same time, there are also Shanyi and Inosuke standing beside him.

Of the three, only Tanjiro was still wearing a white bandage.

"Kintaro, is that the very powerful senior brother you said?" said

Inosuke with a wild boar hood and staring at Feng Yu.

"Yes, Inosuke, Senior Brother Kazeha is the most powerful person I've ever met

!" Tanjiro's eyes were full of adoration and gratitude, but Inosuke on the side heard this, his body began to tremble, and then he flew out with an arrow!

"Pig Rush!" Inosuke shouted "

Inosuke!" Tanjiro didn't expect Inosuke

to

attack Kazeha directly, and hurriedly shouted, trying to stop his behavior.

It's just that Inosuke will listen to

it Feng Yu looked at Inosuke who was rushing towards him, and couldn't help but feel a little surprised.

Then, it was a sideways "pig spurt" that

dodged Inosuke! Inosuke reacted quickly, and after being dodged by Wind Feather, he immediately turned over and jumped, adjusted his posture, and attacked towards Wind Feather again.

"It seems that this kid is recovering well, and his energy is so vigorous!"

the butterfly on the side covered her mouth and let out a hint of laughter.

"Hahaha, Kentaro's senior brother, you are really strong, I want to challenge you!"

Inosuke shouted, and then his entire limbs fell to the ground, like a wild beast, and his whole body was terrifyingly low.

Inosuke's boar hood spewed out a stream of white air, and then crawled on all fours, attacking towards the wind feather.

But soon, he was easily dodged by Feng Yu, as if playing with a little wild boar, and couldn't touch his clothes at all.

"Yaga, you are a strong man, you are not allowed to hide all the time, come and duel with me!"

Inosuke couldn't help but get annoyed as he watched Feng Yu easily dodge his attacks every time.

"Inosuke, don't make trouble!"

Tanjiro shouted, because he saw that Fengyu didn't speak, and thought he was going to be angry, so he hurriedly stopped Inosuke from shouting.

"Well, since you're going to duel, then I'll do what you want!" said

Feng Yu calmly, and then his whole body was ready to attack.

"Hahaha, that's it!"

Inosuke laughed when he saw this.

Then he started attacking towards Wind Feather again.

"Bang Bang!" Feng

Yu didn't dodge, just kept blocking Inosuke's attack, and said while blocking: "The attack strength is too small, the speed is not good, your body is very tough, but you don't make good use of it!" "Yaga, you can't dodge

it!"

Inosuke was very angry at the moment, because he had no way to deal with Feng Yu, watching the other party stroll leisurely, easily blocking his own attack, and also pointing out his shortcomings.

But the strong sense of conceit in his heart made him almost explode.

"The toughness of your body is your strength, and your attacks are scattered, like an undisciplined beast, using only brute force, crazy attacks.

"Your next direction of training should be a good exercise, how to use the toughness of your body to make regular martial arts attacks!" Wind

Feather didn't care that Inosuke didn't listen, but he could see the picture of him being raised by a wild boar since he was a child, and then constantly hunting and surviving in the forest.

In the end, according to the breathing of the wild boar, he created his own breathing method, although his physical fitness continued to improve under the effect of the breathing method, but the law of combat was not orthodox.

It can only be every random attack.

As long as the strength is stronger than him, he can quickly find out his shortcomings and deliver a fatal blow.

"Bastard

, bastard, bastard!" Inosuke shouted frantically

, but Kazefa didn't want to play with him any longer, turned around slightly, and then put the knife on Inosuke's neck.

The air suddenly fell silent

, and Inosuke's body stopped in mid-air, trembling constantly!

"Damn..."

, a reluctant voice shouted from his mouth, and then he fell to the ground and fainted.

"Inosuke!"

Tanjiro shouted, and then ran quickly.

"Wait, Tanjiro, Aoi said your injuries aren't healed yet, you can't run!" shouted

Shanyi behind him.

also chased Tanjiro

and came to Inosuke's side to care about him, while Zenyi was concerned about Tanjiro's injury.

Feng Yu watched from the sidelines

, for some reason, a terrible thought came to his heart...

"Why do you feel weird when you look at these three people..."

"Poof!" "

Feng Yu-kun is really amazing, the shortcomings of that child's body have been pointed out by you, it seems that Feng Yu-kun's eyes are not simple!"

Butterfly smiled.

"I observed that the child's breathing method seems to be a bit similar to my insect breathing, but the insect breathing is more about speed, and this child's breathing method is a combination of speed and strength, which is really a very good child. Butterfly

Shinobu said as he looked at Inosuke who fell to the ground.

Wind Feather nodded in approval.

"Inosuke's words, if he can get good training, he will achieve a very high achievement.

"Senior Brother Kazeha, I'm very sorry, but I didn't take care of Inosuke and let him disturb you!"

Tanjiro apologized to Kazefa after checking that Inosuke had just fainted.

"It's okay, it didn't affect me, on the contrary, I'm happy for you to see that your friendship is so good, Tanjiro, this mission is very good, and it also protects your sister and fulfills the original promise.

"However, there are still people in the Demon Slayer who will not agree that you have your beans by your side, so you have to become stronger, strong enough to make them impeccable!"
