I opened the treasure chest in Demon Slayer: Kimetsu no Yaiba

"Senior Brother Haneda, when my father was alive, he once taught me a sacrificial dance, a sacrificial dance used to worship the god of fire, is that the breathing method of the fire attribute you said?" Tanjiro asked suspiciously.

"Hmm!" Of course Haneda Ryuichi knew, but he couldn't show that he knew it completely: "It should be, you have to remember more about this set of sacrificial dances that your father once taught you in the future, this should be a very powerful breathing method, however, this breathing method you practice, even you don't know that it is a breathing method, which means that this breathing method is defective, at least you haven't practiced it all now, so... "

"Tanjiro!"

Haneda Ryu said solemnly: "Now I will teach you the breathing method I have cultivated, but you have to agree to my only request!"

"Senior Brother Haneda, you say!" Tanjiro nodded solemnly, he is a kind and upright person, as long as Senior Brother Haneda's request is not too excessive, he will definitely agree, as long as he agrees, even if he dies, he will do it.

"I practice a fire-attribute breathing method called the Flame Burning Sun Breathing Method, after you practice my Breathing Method, you must not teach it to others without my personal permission, no one!" Haneda Ryuichi said in a deep voice: "You, can you do it?"

Tanjiro's heart tightened, knowing that this was Senior Brother Haneda's test for himself, but also, the other party's breathing method must be very precious, and it is also because he is in the same door as himself, and he can get the trust of Senior Brother Haneda, which is already a very, very touching thing, how can he teach it to others privately!

"Senior Brother Haneda, I promise you, without your personal permission, I will never teach the breathing method to others privately!" Tanjiro said solemnly, with a solemn face.

"That's good!" Haneda Ryuichi smiled and nodded, he believed Tanjiro's words, so he taught his Flame Burning Sun Breathing Method to Tanjiro, this breathing method is actually not very precious, it's just that Haneda Ryuichi said it is serious, for Haneda Ryuichi, there are many more precious than this breathing method, such as the Straight Death Demon Eye, such as the Sun Sacred Body, the Slashing Knife and the Burning Fruit are not bad!

Of course, this is for Haneda Ryuichi, a local tyrant, and for the people of this world, a breathing method is very precious, especially for the swordsman who is fighting on the front line, even more so!

That's why Tanjiro cherishes this trust very much.

The Flame Burning Sun Breathing Method, Haneda Ryuichi spent a morning teaching all of them, and even he taught part of the application moves of the Breathing Method, the reason why it was part of it, because he himself only comprehended the Burning World Red Lotus, as for those moves that required the Burning Fruit and the Sun Holy Body to enhance the power, it is estimated that Tanjiro would not be able to use it!

After the breathing method was passed down, Tanjiro immediately began to practice under the guidance of Haneda Ryuichi!

In the morning, breathing techniques are taught, and in the afternoon, exercises are practiced.

At dinner time in the evening, the two returned!

"Tanjiro, your talent is good!"

Tanjiro as the protagonist of Demon Slayer, his talent is naturally not bad, from now on, except for Haneda Ryuichi, who hangs on the wall, and Hanada Kako, his talent should be second only to Kasumizu.

However, one thing about him that he is better than Xiazhu is that he is the protagonist of the plot, and he really hangs up, not to mention Xiazhu, even if it is a ghost dance Tsuji, it can't be just, right?

But that may not be the time now, no matter how strong Tanjiro is, it will take time to grow, and it is unrealistic for him to challenge Onimai Tsuji now, not to mention Onimai Tsuji, even if it is a lower string ghost, he can't beat it.

"But ... Haneda Ryuichi looked at the young man beside him: "You have to remember one sentence, don't despise any enemy, the enemy I'm talking about here is not even just a ghost!"

"Got it, Haneda-sen!" Tanjiro nodded heavily.

There was also a hint of excitement in his heart, after learning the Flame Burning Sun Breathing Method, he did feel the difference from the Water Breathing Method, his body was more adapted to the fire attribute breathing method, and the use of those fire attribute moves was more handy, better than the moves of the Water Breathing Method, much easier to use.

'Youdouzi, I'm sure I'll find a way to turn you into a human!' Tanjiro muttered to himself.

After about a month of cultivation, Tanjiro's strength has improved a lot, much stronger than the original plot.

On this day, news came from the rice balls.

"Master, master, the headquarters news, there is a small town that has been attacked by ghosts, because it is close to the Narrow Foggy Mountain, and there are no other pillars here, so this task is handed over to you, I hope you can rush over it in the fastest time!" shouted Onigiri standing on Haneda Ryuichi's shoulder.

"Understood!" Haneda nodded.

With such a long vacation, it's time to come to an end, and it's time to do some tasks next.

In front of the wooden house, Tanjiro stood in front of Ryuichi Haneda, and there was no one else beside him.

"Tanjiro, have you decided to go on a mission with me?" Haneda Ryuichi said, "Your beans are still asleep, and they may not be able to join us!"

"It's okay, I'm relieved that my sister is sleeping here, and the teacher is here!" Tanjiro said, you have been sleeping for a long time, and the longer she sleeps, there is no sign of waking up.

However, there are scales left in the near future, and Tanjiro is also relieved, and he is not stubborn and forcibly takes your beans on the road together.

"Before I leave, I have something to give you!" said Haneda, picking up a long knife beside him.

"This is a Hinawa knife, to fight with ghosts, you must have such a knife, it is possible to kill ghosts, only the ghosts whose necks are cut off by the Nichiren knife will die, otherwise, the vitality of the oni is strong, even if the limbs are cut off and the corpse is cut into ten thousand pieces, it can still be resurrected!" Haneda Ryuichi said, handing over a Nichiwa knife in his hand to Tanjiro.

This Nichiren knife is not an ordinary Nichiren knife, but a Nichiren knife made by Haneda Ryuichi himself!

Haneda Ryuichi has experience in grandmaster-level sword-casting, and in the past year or so, he has also been to the village of swordsmiths and communicated with many master-level swordsmiths, his current sword-forging level is definitely the top level, and the Nikwa knife he personally cast is naturally not simple, it is much stronger than ordinary Niklun sword, even if it is fighting with a ghost with a powerful body, it is not so easy to break.

"This, is this the Nichiren Knife?" Tanjiro had his own Hinawa Knife for the first time, and he couldn't put it down with some love and touched it.

"When you pass the test of Fuji Raid Mountain in the future, you will also have your own Nichilun Knife, but now, you are not an official ghost killer team, this knife is considered to be given to you by me in advance, and when you have your own Rilun Knife, it is better to use your own knife!"

Ryuichi Haneda didn't want to change the customs of the Demon Slayer Team.

"Okay, Senior Brother Haneda!" Tanjiro pinned the knife to his waist and said respectfully, "I will definitely complete the trial!"

"Then, let's prepare, we'll set off tomorrow, during the mission, watch more and learn more, and you won't have to do it until you have to!" Haneda Ryu said, and turned to leave.
