"Wow! I really want to see what it looks like inside! How can it be so intelligent?"
"This is absolutely the most outrageous thing I've ever seen in this world!"
"More outrageous than a ghost!"
"How about we talk to Kotetsu and buy it, then take it apart and study it?"
Teiichi put the Yoriichi Type Zero back into the wooden box, he wondered what it would look like if Yoriichi Type Zero were taken apart.
"It's probably just a bunch of wood, gears, and things like that, right?"
"There can't possibly be some kind of crystal or something I've never even seen before, can there?"
"Besides, Kotetsu just a child, and he's backed by the Ubuyashiki Family. He probably doesn't have much of a concept of money. It feels like it's better to exchange his knowledge of forging for money!"
But I have no knowledge of forging!
Teiichi picked up the repacked wooden box and headed towards the workshop.
"But Muzan later, and the Demon Slayer Corps disbanded. Maybe we can discuss it with Kotetsu?"
"If we take it apart and actually discover something, I dare not say too much, but it would definitely be at least 100 years ahead of the world!"
"However, Yoriichi Type Zero is a treasured item passed down through the Kotetsu family for hundreds of years. Would he really sell it?"
"More importantly, is this something that can actually be researched?"
A deep intuition told Teiichi even if he eventually disassembled Yoriichi Type Zero, he wouldn't be able to figure it out.
Just like the potion that turned Muzan into a demon, it is not allowed to reappear in the world.
He skillfully placed the box Yoriichi Type Zero back into Kotetsu's workshop.
Afterwards, Teiichi waited on the roof of Kotetsu's workshop.
Because Teiichi arrived right on time, it didn't take long for the workshop belonging to Tetsumoto Homura to open its doors.
A little guy with a face completely blackened stepped out first.
Teiichi walked over and greeted him:
"Wow, looks like today was another fulfilling day!"
Kotetsu proudly declared, "That's right! And I definitely feel like I'm learning faster now than when I was a kid! It seems I really do have a talent for blacksmithing!"
You're still a child!
At an even younger age, you probably couldn't even hold a hammer properly back then, right?
He's even learning blacksmithing!
Hmm... Teiichi feeling there might be something wrong with the way they check children's talents in the Swordsmith Village?
Or is it that true geniuses can tell if they have a talent for blacksmithing as early as five or six years old?
Similar to a certain point, three?
Teiichi thought about it in his mind but didn't say it aloud. He chuckled softly and looked at Tetsumoto Homura:
"How's the progress on the Nichirin Blade?"
Tetsumoto Homura nodded, his face expressionless, and calmly replied:
"Quenching is complete today; tempering will begin tomorrow!"
"Backfire?" Teiichi, puzzled.
"I know! I know!"
Kotetsu raised his hand and shouted, immediately beginning his story.
"Tempering involves placing the Nichirin Blade back into the tempering furnace, heating it to around 150°C-300°C, maintaining this temperature for several hours to tens of hours, and then allowing it to cool down slowly."
"Looks like you haven't wasted your time studying!" Teiichi praised.
Kotetsu raised his head. "Of course! I'm going to become the best swordsmith in the Swordsmith Village!"
"But I don't understand why we need to use fire back!" Teiichi continued to ask.
Kotetsu explained, "Tempering is because after quenching, although the hardness of the Nichirin Blade Nichirin Blade the standard, it becomes too brittle at this point!"
"If you take it out and use it like this, the blade is very likely to break. Therefore, it needs to be tempered to reduce the brittleness of the Nichirin Blade and increase its toughness."
"Furthermore, in order to make the forged Nichirin Blade more usable, after tempering, they often need to be polished and adjusted, and then tempered again."
"This process is repeated many times until the Nichirin Blade is satisfactory before proceeding with the subsequent grinding and assembly!"
Teiichi, "It takes several hours to dozens of hours at a time, doesn't that mean it will take a very long time?"
"Uh... this..."
When it came to how long it would take to forge Teiichi's Nichirin Blade, Kotetsu had no idea and could only awkwardly look at Tetsumoto Homura.
Tetsumoto Homura glanced at Kotetsu and continued expressionlessly:
"It will probably take another month or so. Your ' Vibrating Blade' technique requires too much skill from the Nichirin Blade."
Nichirin Blade that lacks resilience can easily be destroyed by your attack.
Therefore, I've tentatively decided to backfire ten times. If the desired effect isn't achieved, I might backfire even more!
"Okay, thank you!" Teiichi nodded.
Kotetsu looked at Teiichi and called out, "Uncle Kato, would you like to come eat with us?"
"No, you can go by yourselves!"
Teiichi shook his head.
If you eat according to your own appetite, without telling them beforehand, and just go to eat with them...
Either they themselves won't have enough to eat, or someone else will go hungry.
Besides, if we eat there, wouldn't it be troublesome if the other side prepared their own meals?
After parting ways with Kotetsu and the others, Teiichi returned alone to the house halfway up the mountain.
Seeing that the food wasn't ready anytime soon, Teiichi grabbed his clothes and headed towards the hot springs.
During his time in the Swordsmith Village, Teiichi would occasionally come to the hot springs for a soak.
The only downside is that hot springs in the summer aren't as comfortable as they are in the winter.
It's still pretty good, though!
We arrived at the hot spring.
Warm steam continuously rises from the water's surface, spreading through the air like a light veil, enveloping the entire hot spring pool.
Teiichi walked around most of the hot spring area with practiced ease, finally arriving at his favorite spot.
There's a rock here that's perfect for resting your back and head on while soaking in the hot spring.
As his feet stepped into the warm spring water, it gradually enveloped Teiichi's body.
It felt as if a pair of gentle hands were caressing every inch of his skin, dispelling the soreness in his muscles.
Teiichi's body continued to sink until finally his head disappeared above the water.
A moment later, its head suddenly popped up from the water again.
Teiichi shook his head, removing some of the hot spring water from his hair, and then lay down on the rock behind him.
Teiichi gently unfolded the towel and covered her face.
Teiichi's body gradually relaxed, and his consciousness drifted away.
However, the brain still subconsciously controls the body's blood flow through Breathing Style, ensuring its orderly circulation.
To avoid fainting later due to reduced blood flow to the brain caused by soaking for too long.
Suddenly, a cheerful and charming voice rang out on the mountain path.
"The aroma of tempura, the flavor of sushi sticks, and the lingering taste of daifuku mochi! Udon noodles warm the stomach, and sakura mochi is as sweet as a dream! Taiyaki is piping hot, and dango dances on the tongue..."
Teiichi's consciousness returned somewhat, but he didn't pay too much attention to it.
Until the sound got closer and closer.
Then.
With a 'whoosh' sound.
Teiichi's relaxed body instantly froze on the spot.
