The last boss of the ninja world

"As time slowly passes..." Sarutobi Hiruzen listened to Musashi's words, and the chakra in his body crazily invaded the paper.

"Well," Musashi nodded, and added: "Energy is the energy that exists in the human body, so it can be perfectly stored in the human body, while chakra is the product of the combination of energy and energy in cells. It does not It belongs to the power that the ninja already possesses, so it will be consumed by eating and slowly lose over time, and only a small part will stay in the ninja's dantian for emergencies."

When the First Hokage developed the Yin Seal, he probably also considered the problem of chakra loss, so he focused his energy on it.

Sarutobi Hiruzen did not deny Musashi's theory. As the Hokage, it was impossible for him not to know these knowledge that ordinary ninjas had no access to.

The chakra used by ninjas is generally extracted immediately, and only a small part of the chakra is a natural reaction of the ninja's body to refine the energy stored in the body in advance.

For example, the chakra in the Dantian of the human body and the eight acupuncture points.

[Eight Gate Armor Formation] actually unlocks the body's potential in an instant, releasing the energy and chakra in the eight gate points, allowing the ninja to surpass the level of the shadow in a short period of time.

The amount of chakra in the body, the lack of chakra in the body, etc. usually refers to the amount of chakra in the Dantian.

The key element of chakra is [refining]. The speed of [refining] chakra is the core point that determines the upper limit of a ninja.

of course there are exceptions.

For example, the Jinchūriki have tailed beasts living in their Dantian. In addition to their own chakra, the chakra of the tailed beasts can also be used in a certain proportion based on their compatibility with the tailed beasts.

There are also fierce people like human tailed beasts. Their physical talents are different from ordinary people, so they have much more chakra reserves in their bodies than ordinary people.

Chakra is a power that everyone has!

Ordinary people's chakra is lost faster than the natural refining speed, so they cannot use ninjutsu.

The ninja's chakra is lost slowly or at the same natural refining speed, and the ninja can also refining chakra quickly, so the ninja can use ninjutsu.

The chakra of a strong person is lost at a significantly slower rate than the natural refining speed. Even if one does not learn refining techniques, there is still a steady stream of chakra in the body that can be used.

There are also other types, such as Zhongwu. His body can also absorb the natural force between heaven and earth. If he does not find a way to get rid of the excess energy in his body, he will go berserk every once in a while because the natural force exceeds his ability to bear.

"Okay, it's full."

After a while, Sarutobi Hiruzen released his palm and handed the technique paper to Musashi.

Musashi held the technique paper, turned around and jumped into the [tractor] stance, and attached the chakra-filled technique to the outside of the engine.

As soon as the power exceeding the upper limit of the spell was combined, the engine began to vibrate obviously, as if it was about to explode at any time. Musashi was so frightened that he made a mark with his left hand and was always ready to escape.

Fortunately, the engine did not explode. The valve made a much louder sound than before, and thick steam followed the valve opening and flew toward the sky.

The [tractor], whose scheduled speed was only 30 kilometers per hour, seemed to have been drugged this time. After the turbine started rotating, it suddenly ejected with Musashi.

The speed is so fast that it even feels a little pushy.

"Step aside!"

Musashi shouted, holding on to the tiller with both hands.

"Hey~"

In just one second, the rope was stretched straight.

The keel at the tail of the [tractor] slowly deformed under the huge pulling force.

"Squeak..."

The boulder was not motionless. As the front wheels of the [tractor] spun, dust was thrown into the sky, mixed with the pungent smell of rubber due to friction, and it finally slowly began to move with the [tractor].

"enough."

There were only seven or eight seconds before and after, before Musashi felt distressed, Sarutobi Hiruzen softened first.

"untie."

After pinching out the interpretation seal, the boulder disappeared.

Suddenly without the restraints of the boulder, the [tractor] was like a wild horse, catapulting towards the target pile at the training ground.

Musashi quickly pulled down the [Clutch] to release the power of the engine, and at the same time pulled the hook that fixed the [Inverted Claw], and lowered the [Inverted Claw] at the rear of the [Tractor] to the ground.

The [Inverted Claw] looks very similar to a rake. It embeds itself into the soil the moment it lands, and then pulls the soil out of the ground under the action of inertia.

The speed slowly slowed down, and the [tractor] finally stopped only ten meters away from the target pile.

Sarutobi Hiruzen immediately caught up to check the situation.

Except for the severe deformation of the tail keel pulled by the boulder, the body was not seriously damaged. Only the two front wheels, which were the power output shafts, had their rubber turned into a ball of caramel exuding a foul smell.

This is still solid rubber. If it were a hollow tire, it would have exploded long ago.

Musashi couldn't calculate how much torque the [tractor] had, but looking at the deformation of the tires, Musashi guessed that its torque was at least two thousand Nm.

In fact, Musashi didn't know that the torque of steam engines was inherently greater than that of internal combustion engines. Internal combustion engines were smaller and more economical to use, which was why steam engines were eventually eliminated on small machines.

Large machines still use steam engines more often, such as nuclear-powered motherships, whose power principle is still to boil water.

"How is it different from a train?"

Sarutobi Hiruzen was so shocked that he couldn't speak, but he still pretended to be very calm and wanted Musashi to explain to him the benefits of the [tractor] in all aspects.

"It's called a tractor. Unlike a train running on tracks, it can move on ordinary roads and in fields."

"Tractor? Haha, this name fits the situation very well."

"Hokage-sama," Musashi said, taking out another blueprint from his arms, pointing at the blueprint and saying, "These are two sets of tools that are matched with the tractor. The first set is called a sledge, and the second set is called a comb."

There is no difference in the principle of sledges and oxen-pulled sledges, except that the sledges in Musashi's drawings are at least three times larger than the sledges pulled by oxen.

The comb is similar to the sledge, except that the comb is thinner. It is an agricultural tool used to break the soil into smaller pieces after the sledge is used.

"Is it used for farming?"

Sarutobi Hiruzen frowned slightly.

Musashi quickly explained: "The designed load capacity of this tractor is 6000 kilograms. If it is scaled up, it can theoretically be built into a machine that can pull 6 kilograms."

【Steam Cannon】!

When Musashi said sixty thousand kilograms, the figure of a steam cannon suddenly flashed in Sarutobi Hiruzen's mind. Although he had only seen photos and never seen the real thing, he also knew about one through the information sent back from the front. The steam cannon weighs about 3 kilograms.

If this guy is combined with [Steam Cannon], then the most fatal weakness of [Steam Cannon], which is difficult to transfer quickly, can be effectively solved.

"Hokage-sama, the biggest difference between it and a train is that ordinary people can drive it, as long as they have it and learn to control it."

Musashi did not dare to let Sarutobi Hiruzen think too much. If the old fox thought that this thing should be a strategic material, then ordinary people would have no fate with it.

So Musashi's original intention of designing the tractor was strangled in the cradle.

"Ordinary people can also use it..."

"That's right, Hokage-sama. If you use it to plow the fields, it would take 100 people to do the work for several days, but it can be completed in one day. As long as one hundred units are produced, it will free up [-] farmers in Konoha to do spring plowing and autumn planting at least Ten days’ worth of work.”

Before Sarutobi Hiruzen could speak again, Musashi continued: "Ten thousand people can save ten days of work. They can use these ten days to do a lot of other work."

"No, if they have this machine, they will not think about doing other jobs, but..." Sarutobi Hiruzen denied Musashi's words.

"But what?" Musashi asked pretending to be confused, but he was happy inside.

The old fox also fell into his trap one day and bit the hook he threw.

"Haha," Sarutobi Hiruzen smiled and did not say anything. Instead, he took two puffs of his cigarette and stared at the [tractor], lost in thought.

How can farmers take a break?How could you think of doing other work during the busy farming season?

With this machine, of course they will expand their farming area and look forward to harvesting more food during the harvest!

Good boy, you still want to trick me?

Sarutobi Hiruzen gave Musashi a knowing look and said, "When the war ahead calms down, I will call everyone for discussion."

"Yes, Hokage-sama."

Musashi nodded knowingly and replied.

What Sarutobi Hiruzen meant was to tell him not to be impatient. Whether the [tractor] could be used for ordinary people would wait until he convened a high-level meeting to discuss it before making a decision.

However, who in Konoha now dares to go against the will of Sarutobi Hiruzen?

It's just a process.
