The last boss of the ninja world

With calculations in mind,

So during the next break from practicing chakra materialization, Musashi began to draw his own weapon drawings.

[Real-time Translation] is very powerful. Through the inference of the spell, Musashi initially mastered the correct combination of runes.

but……

The combined technique was too complex to be drawn on a small scalpel.

Even though Musashi simplified many runes, he still couldn't condense them into something brief enough.

Many times, Musashi wanted to ask Shinnosuke for advice.

Fortunately, reason defeated impulse in the end!

Stealing a master is a very shameful thing. No matter how good the relationship is, Shinnosuke may not be willing to teach Musashi the secret technique.

Furthermore, what Musashi wanted to build was a secret weapon. If someone knew in advance that he had the weapon, how could it be considered a secret weapon?

"If we simplify it further, we can only retain one characteristic..."

Staring at the drawing, Musashi kept pulling back his hair.

If it is [Wind Blade], the internal space can just accommodate the two characteristics [Restraint] and [Shape].

If only one characteristic is retained, [restraint] chakra is attached to the scalpel, and [shaping] chakra is formed into a sharp edge, it is really difficult to choose.

Air control consumes a lot of attention, and if you are distracted by either [Restraint] or [Shaping], the power will be greatly reduced.

The combination of spells is like the programming language of the APP. Each rune represents a specific meaning, so there is a limit to simplification. If it is simplified any further, the spell will no longer be valid.

"That's it for now, forget it..."

After struggling for a long time, Musashi finally chose to retain the [Restraint] function.

The drawings were completed, but I always felt that something was missing, and it was very different from the initial requirements, which made Musashi very frustrated.

Fortunately, he is good at one thing and has a good understanding of everything.

After completing the drawing of [Scalpel], Musashi suddenly had an inspiration.

Recently, all his energy has been focused on the practice of chakra materialization, and he has no extra time to practice other ninjutsu.

I had been thinking about developing the [Boiling Release] ninjutsu before, but it turned out that I had traveled through time for more than half a year, but I didn't even have a decent [Boiling Release] ninjutsu.

"The characteristic of [Boiling Escape] is steam, high-temperature steam..."

Muttering, Musashi remembered the existence of trains in this world.

Steam civilization has already taken shape, and in the near future, Konoha will develop into a world similar to modern civilization.

Unfortunately, the Naruto world did not develop thermal weapons in the end.

"Hot Weapons..."

Thinking about it, inspiration suddenly appeared. Musashi slapped his thigh suddenly, then knelt down and began to draw crazily on the drawing paper.

The pen moved like a dragon, and soon an object familiar to modern people appeared on the drawing.

【water gun】!

A water gun that children on Blue Star often play with.

A little different is that the water gun drawn by Musashi does not have a pressurized butt part, but instead has an extra magazine.

No, [water gun] should not be used to describe the things on the drawing.

To be precise, it should be a strange-looking [air gun], a bottle that is supposed to hold water, and the inner space is covered with magic runes.

Through the analysis of [Real-time Translation], the general meaning of the internal spell combination is: [High-temperature and high-pressure gas that is continuously pressurized to a specific threshold].

"Jie Jie..." After the finished product was released, Musashi let out a strange sinister smile.

In the age of cold weapons, if he took out the thing in his hand, he would probably shock all the ninjas and make them unable to stand still.

There is gunpowder in this world. After all, you can enjoy fireworks all over the sky every festival.

It's a pity that Musashi does not have the knowledge to make thermal weapons, but he can use [Boiling Escape] to use high-temperature and high-pressure steam to stimulate bullets to escape. I believe the power will not be much worse.

"Musashi, what are you doing?"

Passing by the door of Musashi's office, Tsunade heard Musashi's weird laughter through the concierge, so she opened the door uneasily and asked Musashi doubtfully.

"elder sister……"

The laughter stopped suddenly, Musashi pretended to cover the drawing of the [Scalpel] on the [Steam Gun] casually, and then invited Tsunade in to observe his finished product.

For a ninja of Tsunade's level, even if he didn't do much research on the technique, he could still recognize the function of the technique on the [Scalpel] at a glance.

I thought Tsunade would praise him, but unexpectedly, Tsunade hit Musashi on the forehead with a blast.

With a straight face, he criticized seriously: "Medical ninjutsu is a ninjutsu that requires adaptability at any time. Depending on the patient's condition, the severity of the operation, the timing of the operation, and the amount of chakra that needs to be injected during the operation will all be different. If you Always thinking about taking advantage of others is irresponsible to the patient!"

Musashi really admired Tsunade's professionalism when dealing with patients, but he did not retort immediately, but waited until Tsunade's anger subsided.

Then he took Tsunade's arm, pointed at the drawing and explained: "Sister, look here, this technique is a switch. When I usually perform surgery, I turn off this combination of techniques, but when an emergency occurs, , I can open it up and make it my weapon."

"Weapon..." Tsunade couldn't understand the technique. In Tsunade's understanding, it was just a symbol of a technique with no practical use, but she didn't expect it to be a switch.

"It's good to use it as a weapon..." Tsunade then realized that she had misunderstood Musashi.

If I criticized him like that before, would he think I was cruel?

"Sister, let me make one for you too. No, let me make one for us medical ninjas. They carry so much medical equipment. If we have this weapon, we don't have to carry heavy ninja bags anymore."

With the [Steam Gun], the [Scalpel] naturally lost its status as a secret weapon, so Musashi made a generous proposal to equip all the ninjas in the medical team with a weapon with special properties.

This……

Tsunade didn't know what to say for a moment. Thinking of her previous criticism of Musashi, she suddenly felt full of guilt.

"Sister, there's nothing wrong with having more weapons. It's for self-defense."

Seeing that Tsunade didn't say anything, Musashi thought that Tsunade didn't like the [scalpel] he designed.

After all, Tsunade's most powerful weapon is her fist, and any weapon is superfluous to Tsunade.

"Ah."

Tsunade nodded.

Musashi was thinking of his colleagues in the medical team, and at that moment, Tsunade seemed to see a brilliance in Musashi.

The brilliance she had seen in her teacher Hiruzen Sarutobi.

I don’t know how to describe it, but that kind of brilliance can only appear in people who care about others.

Musashi didn't know that his image in Tsunade's heart had been elevated. Seeing Tsunade nodding in agreement, Musashi jumped up excitedly.

As long as Tsunade nods, Musashi can take advantage of the opportunity to customize the [Scalpel] and get a chance to leave the base for a short time. He can also use the custom-made [Scalpel] stall to have his [Steam Gun] made. come out.

By the way, I will order two more storage scrolls. The [steam gun] is too big to be carried around.

In addition, the [steam gun] is more suitable for sneak attacks. In a head-on battle, the theoretical rate of fire of the [steam gun] can only be one shot every three seconds, which is far from the fire suppression effect of the thermal weapons on Blue Star.
