Nobita, quickly use your invincible treasure bag to think of a solution!

Zenitsu looked at the iron oxen and iron horses in front of him and didn't feel anything new. He just felt that it was a bit noisy, and very noisy. He covered his ears and shouted, "Uncle Tetsuanamori, didn't you say there was an exhibition? When does it start? And I'm hungry, is there a mixed bathing hot spring where I can take a bath?"

Someone's map was really long. He asked such a long question and only revealed his dagger at the end.

That’s right, Zenitsu actually came here to collect materials. He came here originally for the mixed bathing in the hot spring. Now that he has the chance to experience it, how could he not ask?

"Yes, Uncle Tiedidong, I'm hungry too, bring the food up quickly."

It would have been better if Zenitsu didn't mention it. After he mentioned it, Inosuke remembered that he hadn't eaten for a day and his stomach was rumbling.

"I am Tesanamori, Lord Inosuke, Lord Zenitsu, and Lord Tanjiro. Someone will take you to take a bath and eat. Please get in the car." Tesanamori clapped his hands, and several brass puppets of the same style jumped out and landed in front of everyone. "Nobita, please follow me to see Mr. Ketsutsuzuka. Mr. Ketsutsuzuka has an invention to show you."

As they spoke, several puppets separated the seats of the puppets under Nobita and the others, and each took one, pulling Zenitsu and the others into two groups, one to take a bath and experience the hot springs in the Swordsmith Village, and the other to take Inosuke to eat.

In the end, only Nobita followed Tesanamori who was riding on the brass ostrich and headed towards the village chief's mansion at the innermost part of the Swordsmith Village.

Along the way, Nobita saw that this swordsmith village was completely different from the other backup villages. The swordsmith villages he had seen before were all wooden structures, similar to the houses of today, with fire pits and tatami mats.

However, this swordsmith village is made of brick and stone. Many brick and stone houses were built on the site of the original wooden houses. The whole street was divided into three sections. The innermost section was still ordinary wooden bungalows, the middle section was a construction site, and the outer section was the two-story building that Nobita had seen before.

It looks like the knife maker village has regressed from industrial civilization to agricultural civilization.

At dusk, bathed in the sunset glow, Nobita and Tetsuanamori climbed the stairs under the shade of the trees. Tetsuanamori was still riding his brass ostrich, while Nobita was carried on the back of the brass puppet, the fourth generation of the little rickshaw driver, and the carriage and the people were carried up the mountain.

The mountain still retains its natural scenery. It is not like what Nobita imagined. After entering the mountain, all you can see are big chimneys and steam floating in the air. There are also the simplest forests and the simplest wooden houses.

After jumping down from the brass ostrich, Tetsuka Mori shouted to the woods, "Mr. Tetsuka, Mr. Tetsuka, Mr. Nobita is invited by me."

clap clap clap!

The trees shook, the earth trembled, and many birds were startled. Not long after, a pair of brass claws pushed aside the tree trunks on both sides and stepped out from the bushes.

In the glow of the setting sun, the three-meter-tall giant puppet in front of Nobita exudes a charming metallic glow, with steam surging all over its body, and under the light it is as gorgeous as a rainbow.

When the steam dissipated, a three-meter-tall giant puppet with a round and flat head like a turtle, thick limbs, arms like pincers, and a body like an iron tower appeared in front of Nobita and Tetsukenmori.

laugh--

Steam gushed out, and the lid on the puppet opened, revealing Tiexueshen's sturdy body and his fire-blowing man mask.

Nobita: "..."

What a mess!

The Swordsmith Village has started to open Gundams, and we have the Brass Turtle King. How about the Brass Zaku and Brass Strike Freedom? Brass Unicorn? Brass Banshee?

Nobita didn't expect that he just lent out the invention machine, but the technology tree of the swordsmith village has developed so outrageously. Isn't it steampunk? Oh, it really is. The body of the turtle tyrant is full of mechanical parts, without any trace of circuits.

"Iron Mound, what are you doing?"

Nobita looked at the Brass Turtle Tyrant behind him, and his eyes fell on Steel Mound.

"Lord Nobita, you are finally here. How is it? The Turtle Tyrant Puppet I know is very powerful, right?" Tietuozuka was very satisfied with his work and became very excited.

He is indeed not good at forging the Nichirin sword, but when it comes to making giant puppets, Koutsuka considers himself the best swordsmith in the swordsmith village.

Turtle tyrant?

Is it plagiarizing someone else's name, or is Demon Slayer planning to collaborate with Gundam?

Nobita's mouth twitched, not knowing how to comment.

Chapter 419 The man with three pillars under the moon!

After briefly evaluating the pros and cons of Katsuzuka's homemade Turtle King, Nobita talked to the two of them and finally understood why they became like this.

The story begins when Nobita, Katsuzuka and Tetsunaemori were working to transform the Nichirin Sword.

As we all know, the Demon Slayer Corps has been able to be passed down for thousands of years, not only because of their determination to kill evil spirits, but also because of their breathing techniques that can strengthen themselves, and the Nichirin Sword that can truly kill evil spirits.

The breathing method was passed down among swordsmen. After the efforts of Muzan and Kokushibo, those who mastered the initial breathing method, that is, the Breathing of the Sun, have all disappeared. Even in some written records, the Breathing of the Sun does not even have a name, but only a nickname such as the Breathing of the Ancestor.

Even Tanjiro's ancestor, who was accidentally rescued by Yoshiichi Tsugakuni, inherited the Sun Breathing intact and used it as a form of blessing, passing it down from generation to generation. If it weren't for the protagonist halo of Tanjiro, the Sun Breathing might even have disappeared completely.

As the original breathing technique, the inheritance of Sun Breathing was almost cut off, but other breathing methods were passed down, and many other breathing methods were derived and circulated among swordsmen.

Just like the breathing method, the forging method of the Sun Blade has also been lost in the process of inheritance for nearly a thousand years. The method that can make the best use of the Orangutan Scarlet Iron Sand and Orangutan Scarlet Ore has disappeared in the long river of history. The forging method inherited now can only be said to be a crude use of the ore. Even the forged Sun Blades are not as good as the earliest generation of Sun Blades, and there are even cases of the sword breaking when slashing demons.

It is a shame for a sword forged by a swordsmith to break during use and kill a swordsman. Especially since the swordsman killed was a hero who protected humans from being harmed by evil spirits, so the swordsmiths are even more ashamed.

When you are in trouble, you have to think of new things. Since the forging method is not as good as that in ancient times, you can cast the Nichirin sword in a shape that is more suitable for swordsmen. It is according to this idea that the swordsmith village has cast new Nichirin swords generation after generation.

However, no matter how strange the Nichirin Sword looks, or how suitable it is for swordsmen, the material is still a big problem, and it is a problem that has troubled the swordsmith village for countless generations.

Hotaru Koutsuka is a sword lover, otherwise he would not have lost his temper because Tanjiro broke the Nichirin sword. He also felt guilty because the Nichirin sword he forged broke several times. The Nichirin sword is the life of a swordsman, and if the Nichirin sword he forged breaks, it means killing someone.

Therefore, Katsuzuka has been researching new techniques, trying to infer the previous forging techniques from the swords of the Warring States period (the sword of Yoriichi Tsugakuni), and to improve the existing techniques, hoping to forge a more powerful Nichirin sword.

However, in the process of research, Katsuzuka realized that human power has its limits. Even the oldest village chief with the best forging skills could not use a sword from the Warring States Period to infer the original casting process. The only thing he could do for his swordsman, Tanjiro, was to help Tanjiro sharpen the Nichirin swords passed down from the Warring States Period.

It is also a shame for a swordsman to not be able to use his own sword, but to change his skills and use someone else's sword. It is an insult to his dignity as a swordsmith!

Then, Kōtetsuka saw newer technology!

Tanjiro's sword does not require a tougher material, but instead uses small mechanisms to cause greater damage to evil spirits. Even an ordinary person can use the Nichirin Sword to kill evil spirits.

There is also a new type of Nichirin sword like Inosuke's, which does not require holding the Nichirin sword in hand, but instead integrates the sword into the body, making it look like a demon's supernatural power.

Coupled with the Infinite Train and the Battle of Yukaku, these two huge battles between evil spirits and swordsmen gave Katsuzuka and the others new ideas.

Bigger is better, bigger is beautiful!

Does the Nichirin Sword have to cut off the evil spirit's neck with one's own hands?

If I use a piece of iron containing orangutan scarlet iron to smash the demon's head and break his neck, would that have the same effect as chopping his neck with the Sun Blade?

Coincidentally, the invention that Nobita lent to Katsuzuka and the others finally came in handy!

The invention machine is a prop that "you provide the inspiration, and I provide the drawings and parts."

Under the ideas of "wanting to fight a hundred with one", "being indestructible, even the neck of an evil spirit as hard as steel can be broken", and "a simple and convenient super-large puppet", a small steam-powered robot with an arm that is a miniature pile driver was born.

The capabilities of the Invention Machine are also limited. If you want to create a real Gundam, the Invention Machine can only provide thick design drawings. If you want the Invention Machine to make all the Gundam parts intact, does it mean that the metal content in the Invention Machine is very high?

In short, relying on the first generation of robot models, Katsuzuka and his team also derived a new technology tree. After all, steam engines were not rare. This was the Taisho era, and there were even trains. Was it difficult to get a steam engine and understand its structure?

Then the knife maker village was gone on the road of cyberpunk, and they relied on their steam-powered robots to help cut down trees, open mountains, cultivate land, dig wells and dig canals. In the small knife maker village, there were many talented people.

They are all top craftsmen. Although they are all knife makers, they are of the same lineage as blacksmiths. Therefore, metal craftsmanship is of no difficulty to these craftsmen.

However, where there are people, there are rivers and lakes. Due to the new changes, the knife maker village was divided into the new knife-making school and the traditional knife-forging school.

The traditional sword-forging school is, without a doubt, headed by the village chief's lineage. They focus on forging traditional Nichirin swords and assist the swordsmen of the Demon Slayer Corps in slaying evil spirits.

The new sword-making school studies new techniques, new robots, and new sun-wheel swords, with the mission of killing evil spirits. The power of a swordsman has its limits, but the power of technology is unlimited. If a swordsman cannot kill the evil spirits, then their swordsmiths will take over and kill the evil spirits with the sun-wheel swords they have forged themselves.

When it comes to being familiar with the Nichirin sword, is there anyone who is more familiar with it than these swordsmiths?

The two factions have been arguing endlessly because of their different beliefs, so there was this new product exhibition in the Swordsmith Village, but according to Tetsuganamori himself, the real name of this exhibition should be "Swordsmith Village New and Old School Joint Sword Forging Competition", where swordsmen such as Nobita and Tanjiro who have experienced fighting against evil spirits and even the Twelve Kizuki will serve as judges to decide the future path of the Swordsmith Village.

Nobita: "..."

Sure enough, the plot of Demon Slayer has become more and more incomprehensible. Why did a sword-forging chapter turn into a sword-forging competition chapter?

"Excuse me, what's the power of these giant puppets? Doesn't a steam engine boil water? You're not boiling water here, are you? Could it be an internal combustion engine?"

Nobita pointed at the Kamehameha Gundam in front of him and asked the Tetsuzuka and Tetsuanamori next to it.

Tiexuesen looked at Tietiezu with some embarrassment, not knowing whether he should tell the secret of the fuel. Unexpectedly, Tietiezu next to him had already told it proudly.

Tietuozuka put his hands on his hips and said proudly: "Ghost blood, the blood of evil ghosts. If the blood of evil ghosts is mixed with the powder of gorilla scarlet sand iron, it can create enough power to drive my Turtle Tyrant..."

Nobita could no longer hear what was said afterwards.

WTF?

Using ghost blood as power?

Damn, are you guys in the Knifesmith Village so awesome?

I was wondering why Tanjiro and the others had nothing better to do than to come to the Swordsmith Village in a group. After all this time, you guys are just giving signals to Muzan over here!

Muzan is sensitive to his own cells, which is how he controls the demons. Otherwise, Nobita would not be able to cause the demon cells to collapse by simply imitating the demons' speech.

However, Muzan has now been patched, and Nobita's trick of imitating the evil spirit's speech and killing it is no longer feasible.

In short, the Swordsmith Village's open use of the blood of evil spirits is clearly a signal to Muzan, telling them that there are swordsmiths from the Swordsmith Village working here.

"Then how did you know that ghost blood can be used as fuel? Also, there is no village nearby, and no evil ghosts. Where did you get the ghost blood?" Nobita was very curious about the development experience of Kotsuzuka and the others.

"This is all thanks to the transformation you did on Inosuke, Nobita-sama. It gave me inspiration. I will never forget the magnificent sight of integrating the evil spirit into the Nichirin sword and then into the human body." Koutsuka recalled the scene when Nobita transformed Inosuke, and he was very excited. "Plus, I learned from the legends of the neighboring Celestial Empire that since ancient times, legendary weapons have always undergone blood sacrifices. Some were sacrificed with boys and girls, and some were sacrificed with the swordsmith himself. So I thought, can the evil spirit be used to sacrifice the sword? Can the evil spirit be part of the weapon? So..."

Tiexue Sen took over the conversation and said, "So we asked the Insect Pillar for help and borrowed some demon materials from her for research. In the end, we found that the ape scarlet iron mixed into the demon blood can make the demon blood release a lot of heat, which can be used as our energy source."

Tietuozuka continued, "The research process was quite troublesome at the beginning. There was a shortage of materials, and some ideas could not be put into practice. But after using ghost blood to solve my Turtle Tyrant's energy problem, I relied on Turtle Tyrant to hunt a large number of evil ghosts. I no longer had to worry about materials. Moreover, after obtaining a large amount of materials, our inventions showed a blowout growth..."

Tietiezhong entered into an excited state again, talking non-stop, and even came close to his Turtle King, kissing Turtle King's feet fiercely as if he was looking at his lover.

"You are really brave, aren't you afraid of dying at the hands of evil spirits?"

Nobita really admires this group of swordsmiths, and also admires their boldness.

Tiexue Sen nodded and said, "Fortunately, we have a large amount of gorilla scarlet iron for research. The ghost-striking gun we made can produce the same effect as the sun blade when it blows up the evil ghost's head and penetrates the evil ghost's neck. The only problem is that there is too little ore. We embezzled most of the village's stock, and eventually the village chief held a grudge against us."

Nobita: "..."

Why do you speak so easily about misappropriating public resources?

Without iron ore, what will happen to the weapons of other swordsmen?

If you keep messing around like this, it's no wonder that people will hate you. For things like embezzling public funds and public resources, committing suicide would be the lightest punishment.

Tietuozuka crossed his arms and snorted coldly, "Humph, the old man is so old-fashioned. He can just dig more ore when there is no more ore. He actually said that I wasted ore and that the Turtle Tyrant I made was useless? Can't the old man see the changes in the village? Can't he see my achievements? The head of the evil ghost was turned into an exploded watermelon under my ghost-hitting gun, and there was not even a trace of it left when it died. If I use an ordinary sun wheel sword, the blade may bend when I cut the ghost. A big gun like mine is not afraid of wear and tear at all. Ha, you are an old stubborn man who is stubborn and doesn't change."

Tesanamori said: "Anyway, I'll ask you and the other pillars to judge this sword forging competition. If our new faction wins, we will give you and your friends the latest Sunwheel Sword of our faction, so that you can have more power on your way to slaying demons."

"Zhu? Who else is coming?" Nobita noticed the other people mentioned by Tetsukenamori.

When Tesana Sen heard Nobita's question, he began to list them one by one: "The referees this time include the former Sound Pillar. After he retired, he brought his wife to our swordsmith village, saying that he would stay for a while and have a good rest. There are also the Mist Pillar, Love Pillar, Insect Pillar, and Flower Pillar who are preparing to forge new swords. There is also the Flame Pillar who was injured some time ago and came to the hot spring to recuperate. That's all. Oh, and there are also the three pillars, including Tanjiro."

Nobita: "..."

What is this configuration?

Does Muzan plan to descend upon the Swordsmith Village in person and massacre the entire village himself?

If it weren’t for Muzan, who could withstand so many pillars?

It can't be that all the remaining three upper ranks will come, right?

While Nobita was daydreaming, someone came over and invited him.

"Excuse me, are you Lord Nobi Nobita? Our village chief, Lord Tetsujin Tetsujigawara, wants to see you."

A short-haired man wearing a fire-blowing mask ran over from the side, looked at the Turtle King in front of him as if he was used to it, and turned to Nobita next to him and invited him.

"This is Tiexiansen Qian, my younger brother. However, he is a fence-sitter. He is loyal to the old school headed by the village chief, but at the same time he does not reject our new school's technology." Tiexiansen Gangzang came close to Nobita and whispered, introducing the identity of the visitor with a rather disdainful tone, as if he was talking about a traitor.

Nobita took a closer look and found that the person who came was indeed a modern person, wearing brass spring shoes on his feet, and did not look like an old-fashioned person.

In the knife maker village, the new school uses steam technology and has a steampunk style, with more or less a bit of technological style on them. The old school is conservative in style, does not use the latest technology, and emphasizes the unity of man and nature.

According to Tiexuesen, two-thirds of the villagers have already converted to their new faction, and half of the remaining one-third have already accepted their new technology, and it is only a matter of time before they join them. In the end, only a small group is left, and they are still resisting together with the village chief.

"Since the village chief has invited me, I have no choice but to meet him. Let's go."

Nobita nodded and agreed to accept the invitation. After all, he was the head of the village and had a very high status, so it would be okay to give him some face.

So after saying goodbye to Tesanamori and Iron Mound, Nobita lay on Tesanamori's lead back, and with the support of his spring legs, he quickly moved towards the village chief's house.

……

Maybe because he had too many bad lucks, Zenitsu finally started to get lucky when he came to take a hot spring bath.

In the hazy fog, three graceful figures were looming. Behind the mist, the sounds of women laughing and playing could be heard continuously, which made people yearn for it, feel itchy and restless.

However, when it came to this point and he was about to see the scene he wanted to see the most, Zenitsu suddenly retreated. He hid not far away, blushing secretly, squatted on the ground with his back to the hot spring, poking with two fingers. He did not take a step forward, but instead pricked up his ears, constantly listening for the laughter of the woman in the hot spring.

It can be seen that Zenitsu is a little conflicted.

"Zenitsu, get up, what are you doing here? Why don't you go take a shower? Didn't you say you wanted to take a hot spring bath?"

Tanjiro came to the hot spring carrying Nezuko on his back, and happened to see Zenitsu eavesdropping there alone. He went up and slapped Zenitsu on the shoulder, scaring him so much that he almost screamed.

However, in order to continue eavesdropping, Zenitsu swallowed back the sound that was about to come out because of his lustful desire.

"Hey, Tanjiro, what are you doing~~~ There are people bathing in the hot spring pool, how can I have the nerve to go in?" Zenitsu considered himself a boy with a sense of shame. It would be bad if he accidentally saw someone naked.
