Chapter 9: Earth Release: Factory Construction Technique!

The blood in the sandworm's body accounts for about 8% of its total weight.

For a 100-ton sandworm, the weight of its blood flow is 8 tons, which is equivalent to 8,000 kilograms.

Due to the significantly higher metal content in the sandworm's blood compared to the human body, only 20 kilograms of blood is required to consume 15 kilograms of iron in the beheading sword.

Therefore, a 100-ton sandworm's entire blood supply can produce 6,000 kilograms of metal.

Considering that a kunai weighs 0.5 kilograms and a ninja sword weighs 1.5 kilograms, it can produce 12,000 kunai and 4,000 ninja swords.

Of course, Mukaze would not deplete the sandworm by sucking out all its blood.

Currently, there are four sandworms in the nest, and they take turns to be bled.

Each time, only one-third of their blood is collected. This results in a daily metal production of approximately 2,000 kilograms.

Over the course of a year, this amounts to 730 tons of production, which may be meager compared to the world's production in the tens of thousands of tons, but it is a significant capacity in the ninja world.

Furthermore, Mukaze can increase the production capacity by capturing more sandworms.

For the Hidden Sand Village, this is truly a miracle because the village itself does not have a steel mill and relies on external purchases for steel raw materials.

The most important aspect is stability. Previously, the Faraday Ninja Tool Factory had to rely on external purchases or Mukaze's own extraction of steel and metal materials.

The desert is a resource desert, and it is difficult to extract even ten kilograms of metal from a hundred kilometers of sand. Mukaze himself could not extract one ton in a day.

But now, by simply feeding the sandworms with pigs, cows, and sheep, they can steadily produce the materials needed.

When calculating the input-output ratio, the returns are definitely lucrative. Thinking of this, Mukaze becomes even more excited.

The beheading sword is continuously broken, lengthened, and reassembled. As night falls, the sandworm can no longer bear it.

It has already had one-third of its blood extracted in the past three hours. Despite the anesthesia and calming effects, the massive blood loss makes it restless.

Jak and Ryokan quickly persuade Mukaze, "Boss, the sandworm can't take it anymore."

Mukaze, in his excitement, finally stops. The sandworm beneath his feet wriggles with increased frequency.

"Temari."

"Yes, boss."

Temari took off the giant folding fan on her back and waved it towards the group of cows and sheep behind her. Wind Release created a strong gust of wind that lifted the poor animals into the air before they landed in front of the sandworm.

The sandworm was currently losing blood and in need of nourishment. Without hesitation, it opened its mouth, lined with four sharp fangs, and sucked in the hundred cows and sheep like slurping noodles, swallowing them into its belly.

Mukaze, accompanied by Jacques and Ryokan, returned to the ground.

Gaara: "Sensei, there's a total of 2,300 kilograms of iron."

Beside him, the broken pieces of swords were neatly stacked.

Kankuro, as a craftsman in the factory, was familiar with metal raw materials. "Boss, the texture of this iron is tougher than the materials we used to purchase. If we use them to make ninja tools, I believe the performance will definitely improve."

"However, I just tested them in the blast furnace. They need a temperature above 1500 degrees Celsius to melt into molten iron. But after they cool and solidify, they gradually return to their original shape. How can we solve this problem?"

Kankuro's face showed regret. If the molten iron couldn't be forged and used, it would all go to waste.

Mukaze had already familiarized himself with the properties of the beheading sword when he first encountered it, using Metal Manipulation to understand its characteristics. No matter how the beheading sword was broken, as long as it absorbed iron from blood, it could restore its original form.

The reason behind this is that one of the materials used in the beheading sword is a memory metal. By forging it with ninjutsu and modifying its internal molecular structure, tiny iron-absorbing ninjutsu are created, thus creating a unique beheading sword.

In fact, this beheading sword is more accurately described as a scientific ninja tool. However, it is believed that the original forge smith was unaware of its scientific principles and stumbled upon it by chance.

Mukaze understood the molecular structure of the iron-absorbing restoration ninjutsu technique. He planned to apply this technique to his own puppets. Now, the beheading sword's most important function for him was as a source of raw materials.

Mukaze: "Then let's continue raising the temperature and destroy its internal structure, so it melts more thoroughly."

As a ruthless merchant, he wouldn't sell kunai that could restore themselves through blood absorption. If everyone had these kinds of kunai, who would come to him to buy more in the future?

There's a joke: A manufacturer went bankrupt because their product was of such good quality that customers didn't need to buy new ones for decades. The company couldn't sell enough products and eventually closed down.

Kankuro: "But currently, our blast furnace can only reach around 1500 degrees Celsius."

Mukaze: "It's okay. We'll start building a new factory, using new equipment, constructing higher blast furnaces, and setting up assembly lines."

With a stable supply of raw materials, Mukaze was full of confidence. When it came to ninja construction, they didn't need to hire construction workers. Mukaze chose to build the factory in the desert, two kilometers away from the sandworm nest.

Gaara, Kankuro, Temari, and the others looked up at Mukaze, who was hovering in mid-air.

Mukaze looked down at the flat ground, extended his hands, and shouted, "Earth Release: Factory Construction Technique!"

The ground shook. The earth trembled.

A rectangular factory gradually emerged from the gravel, measuring 200 meters in length, 40 meters in width, and 30 meters in height.

"Electromagnetic Release: Reinforcement Technique."

Metal elements such as iron converged within the factory walls, reinforcing them with steel bars.

The desert wind howled, carrying away the dust from the factory.

A brand-new, fully yellow factory with an area of 8,000 square meters appeared before everyone.
