The last boss of the ninja world

"Report, Hokage-sama!"

In the Hokage's office, an ANBU ninja wrapped in black robes suddenly flashed in front of Sarutobi Hiruzen.

Only the captain of the Hokage Guard, or the ANBU ninja above the rank of captain, can directly break into the Hokage's office to report urgent matters without any approval.

Upon seeing this, Sarutobi Hiruzen immediately waved his hand to signal the Jonin who was waiting for dispatch to avoid him. Then he put his chin in his hands and asked the ANBU ninja, "What's the matter?"

The Hokage Guards are directly under the direct control of the Hokage. Generally, if there is no major incident, they will never use their privileges to break into the office without permission.

What happened in the end?

The negotiations ahead have entered the most critical moment. Now Sarutobi Hiruzen's heart is hanging all day long, always worried that an accident will happen in the village, which will drag down the negotiation process ahead.

The seemingly relaxed Hokage, as the members of the guard who often come into contact with Sarutobi Hiruzen all know, the more he appears to be relaxed, the more serious the situation is.

"Tanino Musashi, made a new heavy-duty ninja tool at the One-day Ninja Tool Shop."

The ANBU ninja buried his head and reported truthfully, emphasizing the words "new" and "heavy" very strongly.

When he heard Tanino Musashi's name, Sarutobi Hiruzen was obviously relieved. The hands that were originally resting on his chin turned to calmly pick up the pipe on the table.

"Bah~"

After taking two puffs of dry cigarette, Sarutobi Hiruzen asked again: "What type and purpose of ninja tool is it?"

"Back to Hokage-sama, we haven't found out yet, but Tanino Musashi has ordered the owner of the ninja tool shop to send someone to ask you whether you want to assemble the new ninja tools elsewhere."

"Not assembled yet?"

"Yes Hokage-sama."

"Okay, I see."

The pipe knocked on the table, and the ANBU ninja received the order and left in a flash.

Before Sarutobi Hiruzen could think about it, one day the clerk from the ninja shop followed the Hokage's assistant to the door of the office.

The store clerk had never seen Lord Hokage before. Faced with Sarutobi Hiruzen's amiable appearance, he just kept talking for a long time without getting to the point.

Fortunately, Sarutobi Hiruzen received the report in advance, so he could bear his temper and guide the workers to tell Musashi's instructions.

"Oh, it should be a more dangerous ninja tool. You can just move it to the No. [-] training ground. I will arrange for someone to pick you up." Sarutobi Hiruzen said pretendingly, "I am here for you." Thinking about it.

training ground one,

On the surface, seventeen ANBU ninjas persuaded all staff and ninjas in training to leave.

Secretly, dozens of Anbu ninjas have sealed off the training ground tightly. Not even a fly can get in without Sarutobi Hiruzen's permission.

Musashi guessed that Sarutobi Hiruzen would attach great importance to his [invention], but he never thought that the old fox would attach such importance to it.

Hiruzen Sarutobi was waiting in person at the No. [-] training ground. When he saw Musashi coming with the escort team, he greeted with a smile: "Well, you boy, you had an idea, so you didn't say hello to me in advance."

"Uh," Musashi scratched the back of his head. He wanted to explain that this was just a civilian ninja tool without combat effectiveness, but then he thought about it. If he really said that, Sarutobi Hiruzen would probably be reluctant to waste a lot of steel to produce civilian ninja tools. 【tractor】.

So Musashi rolled his eyes and had a calculation in his mind.

"Back to Hokage-sama, I came up with an idea at the last minute and just wanted to put it into practice, so I haven't had time to report it to you yet."

"Okay, what's the use of this guy?"

Sarutobi Hiruzen was busy with work, and he had no time to chat with Musashi. After lightly patting Musashi on the shoulder to encourage him, he walked to a pile of parts and asked.

Musashi took out the blueprint and waved to the ANBU ninja on the side. Just as he was about to hand the blueprint to the ninja, Sarutobi Hiruzen suddenly interrupted: "They are not proficient in ninja tools, you might as well tell them how to assemble it."

Old fox!

Musashi secretly said.

Even members of the Hokage Guards, Sarutobi Hiruzen have to be on guard.

In fact, it doesn't matter if you show them the drawings. Currently, only Musashi can draw the technique that can [produce steam]. The core technology is in Musashi's mind and others can't imitate it at all.

But Sarutobi Hiruzen had already spoken, and Musashi could not go against it, so he had to pretend to be unintentional and handed the drawing to Sarutobi Hiruzen, then walked to the parts and gestured to the ANBU ninja how to install them.

Sarutobi Hiruzen, who is known as the doctor of ninjutsu and knows all the non-blood inheritance limits, fell into a state of confusion while holding the blueprint.

The drawings were very detailed. What Musashi gave him was the general design. Next to each structure, the function of the structure was even simply marked.

However, on the right side of the drawing, next to Musashi's three spells marked [Heart] and [Source of Power], Sarutobi Hiruzen could not understand a single rune.

In the eyes of traditional ninjas who have learned rune techniques, the technique drawn by Musashi is a semi-finished product, a failure that has no effect.

But Musashi has slapped many masters of spells and runes in the face with several facts. So far, those masters have not understood the operating principles of the spells sold to train companies, let alone copied them.

No matter what, no one can understand it now, but someone will understand it in the future.

Just like those [forbidden] techniques left by the Second-generation Hokage, there will always be geniuses who can understand them in the future.

"This is?"

As the ANBU ninjas tinkered back and forth, the [tractor] gradually took on a shape, and Sarutobi Hiruzen couldn't help but approach Musashi and asked.

The [tractor] placed in the center of the training ground is an empty frame without a body, only a chassis and an engine. It can be described as crude in appearance.

"Don't worry, count the time, it should be there soon."

Musashi gave up and stepped forward personally to fix the engine on the chassis and connect the drive shaft to the four suspension points.

After everything was processed, about 10 minutes passed.

Just when Sarutobi Hiruzen couldn't bear it anymore, outside the No. [-] training ground, the tailor shop and the food store delivered Musashi's customized rubber tires and a barrel of cooking oil respectively.

Then, while everyone looked at him in astonishment, Musashi put the steel wheel hub into the rubber tire, and then used cooking oil to smear all the joints of the machine.

"Cooking oil is a helpless move. If you have Brother Jiraiya's toad oil, the effect will be much better than cooking oil."

Musashi complained as he pasted the jutsu that had already stored a certain amount of chakra on the back of the engine.

The moment the magic paper came together, it seemed to be magnetic, and the entire piece of magic paper was firmly attracted to it.

"Did he make a seal?"

"No."

ANBU ninjas, you look at me, I look at you, the pupils are full of shock and confusion.

The Third Hokage, Sarutobi Hiruzen, was no better than the ANBU ninjas.

Musashi's technique once again broke common sense, and the technique actually activated on its own!

"Woo, woo, woo..."

After a while, the steam inside the engine broke through the valve and made a roar similar to that of a train deflating, but the sound was smaller.

"Crunch, crunch, crunch,"

As the steam breaks through the valve, the turbine inside the engine spins rapidly, driven by the steam, and drives the gears to transmit power to the two front wheels.

[Tractor] is moving!

Musashi jumped onto the [tractor].

The [tractor] he designed has no reverse gear, no forward gear, or even a throttle. There is only a [clutch] that can cut off power output, and a [grasp] at the end that can act as a brake.

[Tractor] also has no resistance system, and there are only three handles that can be pulled in the driving position.

There are two longer handles, namely the left rudder and the right rudder. Pull the left handle and the [tractor] will turn to the left, and pull the right handle to turn to the right.

The short handle is the [clutch] that can cut off the power. Pulling it down can stop the power gear from meshing.

Musashi's design is very simple. In theory, if the [clutch] is not used, it should be used as little as possible. After all, if you are not careful, the teeth will be broken, and maintenance will be very troublesome.

"..."

Sarutobi Hiruzen watched Musashi spinning around in the training ground several times, and the veins on his forehead were getting higher and higher.

From what he has seen so far, the [tractor] is nothing but useless garbage.

The speed is not as fast as the carriage. When the vehicle is running, the engine still whines. It is not as comfortable as the carriage. Only the steering is easier than the carriage, which has certain merits.

"Alright!"

Musashi saw Hiruzen Sarutobi's increasingly cold expression from a distance of two to three meters. He immediately threw out a rope, tied it to the iron fence of the training ground, and then tied the other end of the rope to the tail of the [tractor].

"Crack, crack, crack..."

The moment the rope was tightened, the iron fence snapped, and then one by one was pulled out.

Sarutobi Hiruzen finally realized that something was wrong, and immediately made a seal and shouted: "Earth Release: Falling Formation Rock!"

boom!

The moment the pinch seal was completed, a huge cylindrical stone ten meters high and five meters thick appeared inexplicably in the sky, and smashed into the ground, making a huge impact sound.

The Hokage was indeed the Hokage, and the ninjutsu he released casually caused earth-shattering effects.

"Musashi."

Sarutobi Hiruzen pointed at the cylindrical boulder in the center of the training ground and shouted to Musashi.

No need to communicate, Musashi understood immediately, untied the rope and drove the [tractor] to the boulder.

After tearing off the spell on the outside of the engine, the [tractor] slowly lost power and finally stopped slowly.

Then, Musashi ordered the ANBU ninja to find a stronger rope, tie one end to the boulder, and the other end to the tail keel of the [tractor].

The intended load capacity was three tons, and the boulder obviously exceeded three tons, but Musashi still wanted to give it a try.

He immediately took out a pen and technique paper, and drew a [Chakra Storage] technique paper with a higher output power on the spot. He approached Hiruzen Sarutobi, licked his face and said, "Hokage-sama, please prepare this technique for me." Paper infused with chakra.”

"Inject chakra?" Sarutobi Hiruzen was stunned for a few seconds, but still hesitantly imitated Musashi's movements and placed his palms on the technique.

The moment his palm rested on the technique, Sarutobi Hiruzen's inner eyes seemed to see a bucket of water.

The bucket currently contains a trace amount of Musashi's chakra, leaving 90.00% of the empty space, waiting for his chakra to fill it up.

"Is this... a Yin seal?"

As chakra began to be injected, Sarutobi Hiruzen's expression changed drastically, and he stared at Musashi in disbelief and asked.

"It's smaller, the pattern is smaller." Musashi shook his finger and began to explain: "Hokage-sama, the name of this technique is Chakra Storage Technique Paper. It does have the shadow of the Yin Seal, but it is different from the Yin Seal. Two completely different ninjutsu."

"The Yin Seal stores energy, and what it stores is the purest chakra."

"Of course, the Yin Seal can be stored for a long time, but it will slowly lose over time, so the chakra in it must be consumed as soon as possible to avoid wastage."
