From Demon Slayer, the sword is invincible

"Look who's here! The spirited young man from our Demon Slayer Corps has finally shown up!" Feng Xiaodao shouted happily.

Rengoku Kyojuro looked at Feng Xiaodao and nodded, "You are Master Feng Xiaodao, right? I am really glad to see you here. I rushed back as soon as I completed my mission after receiving the message from Chijuro. I really don't know how to thank you for your father's matter!"

"Okay, let's not talk about this for now. Let's have a good chat with your father first. I just need to take a break!" After saying that, he picked up the reluctant cat and went to the lounge to pet the cat.

Kyojuro didn't hesitate to nod and turned to Rengoku Makijuro, his eyes revealing complicated emotions.

"Father..." Rengoku Kyojuro's voice was slightly hoarse.

Rengoku Makijuro trembled slightly. He looked at his son who had grown up and felt a surge of guilt in his heart.

"Kyojuro...you're back just in time." Rengoku Makijuro tried hard to keep his voice calm.

Rengoku Kyojuro walked up to his father, knelt on his knees and said earnestly: "Seeing that father has regained his spirits, I really don't know how to describe my feelings at this moment. Father, pick up the knife and continue to kill demons. We, father and son, will work together to dedicate ourselves to the cause of defeating evil demons and make the Rengoku family glorious again!!"

A glimmer of pride flashed in Rengoku Makijuro's eyes, but it was immediately covered by self-blame.

"You did a great job, Kyojuro... I'm an incompetent father and you've had to endure too much."

Rengoku Kyojuro raised his head, looked at his father, and said firmly: "Father, let the past be the past. I believe that mother does not want to see us immersed in sorrow. I will shoulder the responsibility of a member of the Demon Slayer Corps and protect our family and companions."

Feng Xiaodao watched this scene from the side and sighed inwardly.

"Good! You are worthy of being my son!" Rengoku Makijuro helped Rengoku Kyojuro up, his eyes full of satisfaction.

"However, father can no longer accompany you, because..." Makijuro repeated the reason he had told Feng Xiaodao before.

After Rengoku Kyojuro heard this, he repeatedly requested Makijuro but he still didn't agree. He could only nod and say, "I understand, father. I will try my best!"

Later, the eldest brother also joined the training team. Although his strength was not as good as Feng Xiaodao, he was able to practice and become a man of the Flame Pillar with the help of a guide to the Flame Breathing Technique, and he also had unique insights into the Flame Breathing Technique.

Feng Xiaodao doesn't mind just wanting to do his best to help the benefactor who helped his father regain his confidence. Such a good thing would not be a surprise to him.

At night, after a day of hard training, the four men gathered in the pavilion in the courtyard to chat.

"Sir Xiaodao, Kyojuro is left in your care!" Rengoku Makijuro had already told Kyojuro about the special operations team. The eldest brother had no objection and was happy to join such a powerful team to continue his journey of killing demons.

"Mr. Purgatory, you are too polite. It is a great thing that Dalang can join the action team. It greatly enhances the strength of the action team. However, after a brief exchange of moves with Dalang today, Dalang's strength has completely reached the level of a pillar. I believe that he will not be able to lead the action team for long!"

Kyojuro said enthusiastically, "I'm still no match for you, Xiaodao-san. It's really fun to fight you. The feeling of exerting my full strength has given me a new understanding of the Flame Breathing Technique."

"Haha, there will be many days like this. In the future, we can learn from each other whenever we are free in the action team. There are many good players in my team, and I believe we will not let you down!" One of the reasons why Feng Xiaodao established the action was to hope that a group of high-quality team members could quickly improve their practical experience through mutual competition.

"Really? That's really great!"

Then they talked about some experiences of killing ghosts, and Feng Xiaodao directly asked the questions in his mind.

"Mr. Purgatory, I actually have another purpose for learning all five breathing techniques. I wonder if you know about the Sun Breathing Technique?"

"Log Breathing Method!" Rengoku Makijuro was in a trance. It had been a long time since he heard this name again.

The eldest brother also recalled and said, "Father, if you know anything, please tell Xiaodao-san. The Diary Breathing Method is very familiar. I think I have seen it somewhere at home."

"I know. I've read a book at home that records the history of the Flame Pillars. It records the Sun Breathing Technique!" Senjuro reacted and said.

The three of them all looked at Rengoku Makijuro, which made the middle-aged man feel a little embarrassed. He pretended to cough and said:

"It's not that I don't want to talk about it. I was just thinking about something. No one has mentioned the Sun Breathing Method for a long time. How did Feng Xiaodao think of the Sun Breathing Method? I don't mean anything else. If you are embarrassed, you don't have to say it."

Feng Xiaodao was not embarrassed at all and said directly: "To be honest, if I want to improve my current skills, I can only hope to learn a more powerful breathing method! I have a hunch that I will definitely face the Demon King Muzan in the future, and no matter how strong he is, it will never be too strong."

When the eldest brother heard this, his blood began to boil, "Father, if it's about defeating evil spirits, you must help Xiaodao-san no matter what, not to mention that the one you're going to face is Muzan! What exactly is the Log Breathing Method, and is it related to the five basic breathing methods?"

"In fact, the Flame Breathing Technique is a school derived from the Sun Breathing Technique. Even the five basic breathing techniques are derived from the Sun Breathing Technique!"

"How could it be so!" The eldest brother and Senjuro were both surprised.

"However, the Sun Breathing Technique has long been lost, and I only know a little about it. Fortunately, the successive Flame Pillars in our family all recorded some things, otherwise I would not know this secret!" Rengoku Makijuro shook his head and sighed.

"Master Xiaodao, do you want to use the five great breaths to work your way back and see if you can find the Sun Breathing Technique?"

Feng Xiaodao said with a firm look in his eyes: "I do think so. No matter what, I must find the Sun Breathing Method and improve my strength, otherwise it will be difficult to pass the level of Demon King Muzan."

Rengoku Makijuro nodded and continued to tell all the information he knew. "As far as I know, the Sun Breathing is a very powerful practice. It is very difficult for ordinary people to practice it, so there are five derived breathing methods. It is said that the Sun Breathing can cause great damage to ghosts!"

Chijuro then asked in confusion: "How could such a powerful breathing method, even though it is difficult to practice, be lost?"

"According to records, many years ago, all the swordsmen who practiced the Log Absorption Technique were hunted down and killed by a mysterious master, and then the technique was lost!"

Feng Xiaodao said directly: "If I'm not mistaken, this must have been done by Muzan or a ghost related to him. He must eliminate things that threaten him."

"I thought so too!" Rengoku Makijuro agreed.

Rengoku Kyojuro patted Feng Xiaodao on the shoulder and said, "I believe you can do it. If you need any help, just ask."

Rengoku Makijuro then said: "Although I know very little information, there is one thing I don't know if it is useful to you. The Sun Breathing Technique is related to the power of the sun!"

Feng Xiaodao nodded and tried hard to recall the animations he had watched to see if this point was mentioned. In any case, it was a gain.
