Simulation: Start with one person

'Is it?maybe……'

Fang Rui didn't hesitate about this, and said with some surprise: "About five hundred kilograms, which is a bit small!"

He originally thought that the Demon Slayer Corps, which had two orangutan scarlet ore and orangutan scarlet iron deposits, had a lot of reserves~

"Because Orangutan Crimson Ore and Orangutan Crimson Iron are relatively special ores, if they are stored in a warehouse lacking sunlight for too long, their quality will be affected, so the amount of ore stored in the warehouse is always the lowest..."

"A ton or so of ore is quite a lot..." Fang Rui raised his eyebrows slightly.

To forge a Sun Lun Knife, you need at most a few kilograms of ore, and one ton of ore can forge hundreds of knives...

Hmm~ It’s really not too much!

The number of members of the Demon Slayer Corps has always been in the hundreds, and one ton of ore is estimated to be...not enough to replace all the members of the Demon Slayer Corps.

but……

Changing knives doesn’t mean replacing hundreds of knives at a time!

Overall, the ore reserves should be said to be...

Should I say more or less?

"It's just to maintain daily needs." Ubuyashiki Yoshiya didn't know what Fang Rui was thinking. He explained: "Forging the Nichirin sword that the team members replaced needs to consume part of it, and the swordsmith needs to consume part of it to research a better Nichirin sword." , some other uses need to consume part of it, and leave some ore just in case..."

"Listen to what you said, if I take half of the ore at one time, won't it affect the normal operation of the Demon Slayer Corps?"

Hearing this, Fang Rui grasped the key to the problem. The reason he collected the ore was just to enrich his inventory. If the cost of obtaining the ore was the lives of many people, he would naturally refuse with all his heart.

"No, it's just that the people in charge of mining will be a little tired." Ubuyashiki Yoshiya answered frankly.

The person in charge of mining is "Yin", the logistics force of the Demon Slayer Corps. The strength of Yin's members is slightly lower than that of other members of the Demon Slayer Corps, but they are much stronger than ordinary people. They are good at mining.

One ton of ore, that is, it takes about a day.

"Yes." Hearing this, Fang Rui nodded slightly, "In that case, I will go to the Sword Forging Village myself."

"Let's go together! I also miss the hot springs in Knife Forging Village very much."

Ubuyashiki Yōya, who regained his healthy body, said that he was very restless and wanted to enjoy his healthy body to the fullest.

Saying that, Ubuya Shiki Yaoya was eager to give it a try, but he just had to say the word "go".

"Lord..." Butterfly Ren's faint tone was a little erratic, like a basin of cold water being poured down on her, causing Ubuya Shiki Yoya to calm down instantly and cast an inquiring gaze on her.

"What's up?"

The special intuition of the Uyashiki clan was telling him that trouble was coming.

"Of course there is something. Although I have great trust in Mr. Fang, there should be a checkup~"

Not sure if it was an illusion, but Fang Rui heard something strange in the Butterfly Ninja's tone.

"...Okay." After all, the Butterfly Ninja had good intentions, so Uyashiki Yaoya did not refuse.

Then, he turned his eyes to Fang Rui and opened his mouth to speak.

But before he could say anything, Fang Rui said first, "Ms. Butterfly is right, so I asked Yiyong to take me to the Knife Forging Village. You stay here for a good physical examination..."

After saying that, Fang Rui gently patted Tomioka Yoshiyuki on the shoulder, and Tomioka Yoshiyong nodded slightly to indicate that there was no problem.

Although he really wanted to go back to Saagiri Mountain to talk to Qio Usagi and others about what was on his mind, but since his benefactor needed his help, it was appropriate to postpone his return home.

"Then...bye."

After saying that, Fang Rui and Tomioka Yiyu left the place.

The backs of the two disappeared around the corner of the wall. Yoya Shiki retracted his gaze and said to the Butterfly Ninja: "Let's go! Complete the physical examination early and leave early."

Saying that, Uyashiki Yoshiya stepped forward, followed by two lolita.

The Butterfly Ninja followed, having some doubts about what happened before, so he asked, "You seem to care about that person very much."

"Of course I care. He has a very special ability, but it is not a blood ghost technique. He has no ill will towards the Demon Slayer Squad, but his ill will towards evil ghosts is more obvious. Moreover, there is a demand for Orangutan Crimson Ore and Orangutan Crimson Sand Iron. Does he control the swordsmith? Other uses…”

"Besides, based on his confident tone and some details, it should be true that he has a lot of information about ghosts."

"So... I want to get closer to him and get more information from him. Then... the casualties of the team members may be reduced."

and……

People with special abilities!

Where did the special abilities come from? !

Born, or acquired for some reason...

Looking at Uyashiki Yōya's back, Butterfly Shinobi was silent. The Demon Slayer Corps had always suffered heavy casualties. As the controller of the Demon Slayer Corps' logistics and medical care, she knew this very well.

………………

The sword-forging village is far away from the headquarters of the Demon Slayer Corps, but it's not particularly far away.

After all, the importance of the Knife Forging Village is obvious, and it is difficult to provide support if it is too far away.

On the other hand, because the Nichirin Sword needs maintenance, Zhu often goes to the Sword Forging Village, so the Sword Forging Village is considered a relatively safe area.

And if you want to go to the Knife Forging Village, you need special means, that is, you need to cover your eyes with a bandage.

After a while, the two arrived at the Knife Forging Village.

The village where a group of knife makers live does not feel special. It is more prosperous than ordinary villages, but not as lively.

The forges are clustered on one side of the village, and the warehouses where the ore is stored are also in that area.

Before going to the warehouse, they needed to talk to the village manager, so the two of them headed to the village chief's location.

"……no problem."

Regarding the request made by Tomioka Giyu, the village leader of the knife-forging village, Teichi Heyuan Tetsujin, agreed very readily.

"Besides, there is another thing..."

"Please tell me..." Kawara Tiezhen signaled Fang Rui to speak freely.

"I want to see the forging technology of Nichirin Sword."

Regarding Fang Rui's request to see the swordsmith village's skills, Kawara Tiezhen did not get angry, but asked: "Why?"

"I'm going to forge a special sword for two people, but I... don't know much about the forging method of the Nichirin sword."

Fang Rui shook his head slowly and said it very tactfully.

What is meant by not knowing much, it should be called not understanding at all.

"You..." Kawara Tiezhen looked at Fang Rui carefully, focusing on his face, hair, hands and other parts, and his tone gradually became stiff, hiding dissatisfaction, "You are also a swordsmith?!"

Whether a person is a knife maker can be judged by some details.

For example, people who often forge iron must be relatively strong, and their hands will have traces of forging, such as scars and calluses...

"To be precise, I am a weapon refiner. I am good at making various weapons and wonderful instruments."

"Item Refiner?!"

In response, Kawara Tiezhen's tone became increasingly dissatisfied.

Slender white hands, fair and handsome face...you told me that you are a blacksmith? !

Do you think I believe it or not? !

"If you don't believe it, I can show it to you."

Kawara Tiezhen's tone was too obvious, allowing Fang Rui to easily detect the other party's malice. Combined with the other party's sight and some random information, he could guess the reason for the other party's ill feeling.

And he happened to be somewhat interested in ores and forging technology, so there was no problem in proving it.

"Oh~" Hearing this, Kawara Tiezhen was a little surprised. If he was so confident, the possibility of Fang Rui being a swordsmith increased a bit.

"Since you suggest so, then come with me."

With that said, Kawara Tiezhen took the two of them to the workshop.

In the workshop, there were not many craftsmen who were forging knives. Most of them were gathered together and discussing something.

Exchanging insights is also a way to improve forging skills.

Seeing the village chief, the craftsman who was idle for the time being nodded slightly as a greeting. If he said anything, it would definitely affect the craftsman who was forging a knife.

"Please……"

Next to a stove, the short Kawara Tetsujin, wearing a fire man mask, said.

Fang Rui turned his attention to the forging table, where all the corresponding tools were available, and the initially tempered ore was placed in a wooden box.

Fang Rui didn't know whether there was a special forging method for the Nichirin Knife, so he used ordinary knife forging techniques, and the knife he forged was not a Japanese-style knife, but a ring-shou knife.

The style is relatively ordinary, without any fancy patterns engraved on it.

The craftsmen who were watching Fang Rui's knife forging all expressed their opinions:

"What a beautiful knife!"

"The Hundred Forged Sword! It's so powerful..."

"Isn't it a bit fast? A hundred-forged sword was forged in a few hours..."

Either surprised, admired, or confused...

Various emotions were reflected in the conversation between the craftsmen. Fang Rui held the Huanshou knife and cast his gaze on the blade, as if he wanted to see if it would change color.

however……

'I don't seem to have learned the breathing method, and whether the forging method is correct...'

'never mind……'

With these thoughts in mind, Fang Rui withdrew his gaze and turned to the chief of the Bladesmith Village.

Kawara Tiezhen, who was watching the whole process, already had a preliminary understanding of Fang Rui's skills and was a craftsman with relatively rich blacksmithing experience.

Now that his identity has been proven, Kawara Tetsujin must keep his promise.

"Come with me!"

With that said, Kawara Tiezhen turned and left.

The craftsmen in the village are all trained one-on-one. There is no need for books to assist in the teaching process. It is just talking and practicing at the same time.
