From Demon Slayer, the sword is invincible

"What's so strange?" Feng Xiaodao asked directly.

Holding the new Sun Blade in his hand, Feng Xiaodao was very satisfied with it and did not find anything wrong with it. It could be seen that this was a perfect Sun Blade.

Hotaru Tetsuzuka thought for a moment and said, "The first strange thing about this knife is its sharpness. According to our grinding method, the sharpness of this knife should be perfect. However, my intuition as a master knife maker tells me that this is not the limit of this knife. It should be sharper. However, no matter what method I use, I can't improve its sharpness!"

Feng Xiaodao nodded to indicate that he believed what Gangtsuzuka Hotaru said. Although he felt that this kind of thing was the most mysterious, the words of this craftsman who loved knives so much were still worth his trust.

Feng Xiaodao held the Sun Wheel Sword with the blade pointing downward and gently released his hand; the Sun Wheel Sword fell straight down, piercing through the wooden floor and even the ground below. The whole process was extremely smooth and silent, leaving only the handle on top.

This sharpness really satisfied everyone, even Feng Xiaodao couldn't believe that such a sharp knife had not reached its limit. So he pulled out the knife again without resistance and looked at the blade.

The blade was straight and smooth, reflecting Feng Xiaodao's handsome face, without a single flaw on it.

"Let's put this aside for now. I can't see any changes. Tell me what other strange things you found!" Feng Xiaodao was already very satisfied with the current sharpness of the Sun Wheel Sword, so he didn't worry about this issue for the time being.

Hotaru Tetsuzuka said hesitantly, "As a sword, this sword is already our pinnacle work, but it seems that this sword cannot change color?"

"Change color? What color change? How can an old single man like you forge a knife that can change color?" Feng Xiaodao blinked his big eyes, his face full of curiosity.

Seeing Feng Xiaodao's strange and inquiring expression, Tietuozuka Ying hurriedly explained awkwardly: "Mr. Xiaodao, that's not what I meant. You misunderstood. And I'm not a single man. I just dedicate my life to the knives I love!"

"Doesn't that mean you don't have a wife?"

"The forge, the hammer, the whetstone, and the flame are my wives!"

"I didn't realize that Mr. Hotaru Tetsuzuka is quite old and has so many wives!"

All the swordsmiths, including the village chief, were amused by what he said, and they all looked at Kotetsuzuka Hotaru while trying not to laugh.

Oh my god, how did it become like this? She said anxiously: "She is not the kind of wife you said!"

"What kind? The kind that gives birth to a child? You are amazing, Mr. Tsukahara, you can do this! I admire you!"

"Haha!!!"

"Okay, teacher, stop making fun of Master Hotaru Tetsuzuka!" Teriyachi, who was standing by, finally couldn't stand his teacher getting too playful and reminded him.

Feng Xiaodao was afraid of upsetting his swordsmith, so he said, "Don't mind, Mr. Tsukaharu. I was just joking to lighten the mood. Let's get down to business!"

Tietsuzuka Hotaru was almost getting anxious. She didn't expect Feng Xiaodao to be so sharp-tongued and like to bully honest people. However, she was not angry with him. This kind of swordsman was quite interesting and was better than those arrogant ones.

"Actually, it's like this. We all know that the Sun Blade can change color according to the user's breathing method, but this sword doesn't seem to be able to do that. We tested it before it was fully formed, and no matter what breathing method we used, it couldn't change the color."

Feng Xiaodao immediately understood what it meant. This was indeed quite interesting. "Will that affect its use and ability to kill ghosts?"

"No, it won't have any effect at all. I think changing color is a sign of the Demon Slayer Corps swordsman. It's a pity that we can't change color!" Hotaru Tetsutsuzuka said affirmatively, with a bit of stubbornness of a perfectionist in her tone.

Feng Xiaodao heaved a sigh of relief after hearing this. As long as it doesn't affect the use, it's fine. He doesn't have that much time to waste here. Although it's not that cool, it's still an advantage to be a Yin (human) ghost!

Although Hotaru Tsuchiya said so, Feng Xiaodao still decided to try it himself, so he took a deep breath and activated the Thunder Breathing Technique. For a moment, everyone in the room felt their hair stand on end, as if they were feeling the pressure before a storm.

But no one was afraid. They were all staring at the Sun Wheel Sword in Feng Xiaodao's hand, expecting something magical to happen.

The blade began to tremble, and a golden light flashed across the blade, but it only flashed for a moment, and then there was no change. Feng Xiaodao frowned slightly, feeling a little unbelievable.

If you say it won't change color, it's because it only flashes a little; if you say it will change color, it will be useless no matter how much I increase the use of Thunder Breathing.

Seeing this, the expectant look in Tietsuzuka Hotaru's eyes dimmed instantly. He had thought it was a problem of strength, but now it seemed that even a swordsman as powerful as Feng Xiaodao had not changed. Could it be that there was really a mistake in forging the sword? But the sword was obviously excellent.

Feng Xiaodao held the knife quietly and did not give up. Instead, he fell into deep thought. He thought to himself, "It seems that I have no choice but to try this method!"

Everyone saw Feng Xiaodao suddenly hold the knife with both hands and close his eyes. A strong sharp feeling began to appear faintly in the surrounding space. Although the movement was not bigger than before, the feeling was as clear as if it had pierced into the brain.

That's right, Feng Xiaodao was ready to use the sword intent to try it out. He closed his eyes and recalled the feeling when he had just realized the sword intent. He used the sword intent to communicate with the sword in his hand and used his spirit to sense everything about the sword.

Suddenly, a buzzing sound began to emanate from the blade in Feng Xiaodao's hand, and the thundercloud pattern on the blade began to gradually light up from the base of the blade to the tip.

Until all the thundercloud patterns were lit up, a golden light instantly flashed from the blade. Although the golden light was as delicate as the texture, the amazing color attracted everyone's attention.

Hotaru Tetsuzuka was so excited that he clenched his fists tightly. He felt it, he felt that the sharpness of the knife had reached a new level. It turned out that it was not that his method was wrong, but that the knife had finally found a master that it recognized.

Only the most suitable person can bring out its full strength. This knife is really amazing. Even the knife makers are reluctant to let go of their eyes. Is this really a knife forged by everyone? It's amazing.

Feng Xiaodao had also opened his eyes. When the thundercloud pattern lit up, he had already communicated with the knife through his sword intent, and he had felt all the changes of the knife through his sword intent.

Now that the goal was achieved, Feng Xiaodao made a sword flower, sheathed the Sun Wheel Sword magnificently, and said happily: "There is no problem with the sword, let's go find a place to test the sword, I can't wait to swing the sword!"

Everyone cheered in unison, wanting to see how this perfect Sun Blade would shine in the hands of the most powerful swordsman. It is very likely that this will be a legend worth passing down for countless generations.

Only Feng Xiaodao thought to himself: "It seems that I can't be an assassin. I wanted to give it a try!"
