"Niwa."

Makoto didn't answer, but waved his hand, and the man who had been following Makoto from the beginning stepped forward, this man was around 30 years old, wearing a standard Konoha green vest uniform, although it looked clean and tidy, but if you look closely, you can see the dirty traces hidden in the neckline, cuffs and other places of the uniform, although it is very strange that Makoto Uchiha is followed by a Konoha ninja who is not wearing the uniform of the Uchiha family, but the people who see him are all attracted by the two boxes behind him.

Both chests are not large, although they are both slender and long, but the width can only accommodate two scrolls placed side by side - the reason why the scrolls are used as a measure of the size of the chests is because the two chests placed on top of each other are exposed on both sides of the regular scroll ends.

Although the clothes I wore were not very clean, the two boxes and the scrolls in them were full of a sense of neatness that reminded me of cleanliness, rules, regularity, and other praise words.

From top to bottom, or from left to right, according to the thickness, color, and length of the different scrolls, the two boxes of scrolls are placed strictly in a certain order, which also makes people pay attention to what is behind this unremarkable man.

"Yes No. 57 ......"

The man put the box down, and as he counted it, he carefully pulled out a scroll with the number 57 written on it, and stamped it.

The appearance of a machine, about two people tall, with a complex structure made of iron, in many places less than a finger wide, makes it look very delicate.

Cheng pointed at it and smiled at the members of the Cat Finance Chamber of Commerce who looked over: "Steelmaking furnace...... Model. ”

A keen sense of smell was a trait shared by these big businessmen, and after making sure they had heard correctly, the association of the machine's name made them all change their faces and look at one of them together.

Wearing cat earrings, the tall woman knocked down her pipe, and finally revealed her calm and pungent side as a merchant, she leaned forward and sat back, lowered her head, and sat cross-legged and said slowly: "Makoto-sama, what do you mean by this?" ”

"You're mistaken." Makoto's voice was not higher than that of the other party, but his tone did not mean the slightest concession, and he calmly explained: "As you can see, this is a steel-making equipment, and after Niwa's transformation, it is more efficient than any similar equipment in the current ninja world, and at the same cost, it can produce twice as much steel as other types of furnaces - not to mention manual production. ”

"Artificial?" Despite the anger in her heart, Catwoman keenly grasped the inappropriate word.

In other words, it is this vigilant antagonism that makes this woman, who is now one of the largest weapons providers in the ninja world, extremely calm.

Everyone understands the word steelmaking, and with the word furnace, Cat Po, who is the largest buyer of iron ore, is no stranger to her—although she is mainly engaged in providing weapons and ninja tools, and has hundreds of craftsmen making utensils under her hands, after all, it is already this era, and she cannot still adopt the backward production method of handicraft workshops as when the samurai still existed.

At least on the import side, as it was a few decades ago, the requirement for artisans to start crafting weapons from the smelting of iron ore has long been phased out.

Cat Po naturally has its own weapons production base, in which, there are many blast furnaces that are constantly smoking day and night, providing relatively high-quality steel raw materials for the craftsmen who make the tools under Cat Po, skipping the stage of starting smelting from the most primitive iron ore, and the resulting benefit improvement is also one of the secrets that the weapons and forbearance produced by Cat Po can crush many well-crafted, and even known as the "master" of the original iron country master-level craftsman's workshop, so as to dominate one side.

When Catwoman was still very young, the production of weapons and ninja tools and other equipment was monopolized by the craftsmen of the Iron Country, and it was with these secrets of continuous improvement that Catwoman was able to defeat them and eventually occupy most of the market in the ninja world.

Therefore, in the face of this more efficient iron-making furnace that Makoto took out, Cat Woman would be so sensitive and angry, she made up her mind, if Uchiha wanted to meddle in her own business, she would rather go against the teachings of the immortals, and she would fight to the death, and swear to the death with the bastards of Uchiha.

"Yes, handmade." Makoto nodded, as if he didn't see the cat woman's seemingly calm but actually fiery expression in her eyes, and he said to the young Konoha ninja, "Niwa, demonstrate." ”

Niwa smiled excitedly, ignoring the big businessmen and big bosses who were full of millions, and just caressed the delicately shaped machine as if it were a treasure, and muttered, "No. 57, No. 57, you have to do a good job." ”

He turned around, and when he faced the people of Makoto and the Cat Finance Chamber of Commerce, he didn't have any expression, he pointed at the machine as if he was dealing with business, and said, "This is the mine entrance, this is the transfer port......"

The tone is poor, devoid of emotion and ups and downs.

Makoto coughed dryly and interrupted him, "Niwa, you just have to cover it up. ”

Niwa glanced at Makoto, his eyes finally had a third look other than looking at machines and people, he didn't speak, he opened a box that was channeled out with the random device, took out a box of things, and poured it into a cavity at the bottom of No. 57.

Everyone present could clearly see that it was a box of finely crushed iron ore.

Niwa took out another box of things from the box and prepared it the same way, but poured it into a different place, this time a box of charcoal powder.

Then the young man made a seal, and finally had the mood to follow the big businessman, who was still calm and calm, but was already faintly impatient, explained: "Because the scale of the combustion is too small, and it is a demonstration, I will use ninjutsu instead of the flame of charcoal powder to increase the temperature, if it is the actual size, No. 57 has no problem in this regard at all." ”

As he spoke, he finished sealing, and carefully spat out a mouthful of flame, and the charcoal powder in the furnace was immediately ignited, and the whole interior of the furnace became clear.

Niwa did not stop the flame in his mouth, so the machine named No. 57 suddenly "came to life" with this flame as the power source.

Under the reflection of the jumping flames, the steel machine made a creaking sound, although it was only a delicate model, but countless gears, tracks, levers moved in unison, and the scene of white steam and thick black smoke rising everywhere still gave people a "roar" like a spectacular feeling.

I don't know how it works inside, but after a while, Niwa maintained the ninjutsu flame in his mouth, and his fingers moved slightly, and Chakras, which was connected to the machine, pulled the valve in it, and the place where Niwa introduced it was explained as a "liquid transfer port" flowed out of the red and dazzling molten iron.
