What seemed to be a thick stack of documents, Oromaru only looked through them for a few minutes, hastily skimmed through them, pulled out two copies from them, and threw the others into the trash.

Seeing Daimaru's unceremonious behavior, the mask just smiled. It's not surprising that a talented and young boy would do such a thing, and the face armor was not much better than Daimaru at his age.

Today's highly decorated Daimaru is also a celebrity among the sand ninjas, and along with the name of "Red Sand Dust", there is also his black history that makes people laugh in the past.

It is already very face-saving to throw some of the predecessors' "painstaking" fraudulent funding plans into the trash, without scolding.

"There are still two copies that are still in sight?"

"So-so! It may not work out, but the idea is very good, and even if it doesn't work out, it should be able to validate some ideas and find some valuable by-products......"

"Verify the idea, I know, ninjutsu research this kind of thing, there is no smooth sailing......"

Even if the air combat forces are successful, it cannot be completely denied that the several unsuccessful attempts of the past few decades, and the well-informed face armor that is over forty years old will certainly not be without knowledge,

"Valuable by-products, what to say?"

Orochimaru tilted his head and thought for a moment before replying:

"It's like I was going to develop a special medicine for coughing, but it turned out that it was useless to treat cough, and the effect of treating constipation was very good......"

Daimaru's indecent analogy made the face nail laugh:

"That's right.,Sometimes some of the discoveries that make people laugh and cry are so unexpected.,Back then, in order to reproduce the magnetic escape blood inheritance limit from the body of a Shouhe, although it failed,But the by-product sand ninjutsu is also very easy to use......"

"That's what it means!"

The face armor patted Daimaru on the shoulder and said:

"According to your thoughts, if you have any opinions, please ...... them"

Daimaru nodded:

"Give me a few minutes to take a closer look at ......"

As he spoke, Omachimaru carefully wrote down his opinion on the two proposals.

One of them is the "diving carrier" that Daimaru can barely look at.

The evaluation is: cautiously optimistic, it is recommended to do a good job in wind tunnel and ship model experiments to optimize the line type.

As for the propellers or anything, there is no need for Daimaru to teach them, on large diving carriers, a relatively rudimentary steam-powered auxiliary propulsion system has been designed.

That's right, there are steam-powered trains and steam paddle steamers in the ninja world, and propeller boats are relatively rare.

Although the oil industry has not developed, and there is no shadow of gasoline and diesel engines, because of the existence of ninjas, the stupid and rough steam engine is more popular, regardless of the background of the times, it really has a bit of steampunk flavor.

What surprised Daimaru even more was that the very few suicide sub-body charge blasting puppets carried by the mothership were actually equipped with something similar to a horizontal spin thruster.

When Daimaru saw the drawings of this thing, he was so surprised that his jaw almost dropped.

Because of the existence of Chakra, the scientific and technological level of the ninja world has indeed been affected by the extraordinary power of ninjas, but in terms of intelligence and imagination, it is no worse than that of real scientists, and some whimsical ideas generated according to local conditions really make Daimaru breathtaking.

The puppet technique that has been developed for decades really has a lot of surprises that seem "inconspicuous" but very effective, and those experienced puppeteer predecessors have goods in their stomachs.

Of course, Ichikawa, who was very interested in Daimaru, did not want to design a battleship, but wanted to develop a water battle puppet, so most of the design was based on the ninja's chakra drive.

Another thing that Daimaru finds interesting is a miniature battle fortress with limited movement capabilities.

Carrying heavy ballistas, light fire network weapon systems, the target is very clear, anti-air, siege city, large psychic beasts and even tailed beasts.

The effect is unknown, but the idea is good.

Daimaru's opinion is that it is worth trying, and it is recommended to consider steam power assistance.

If you use chakra to drive, I don't know how many people will need to maintain it, this thing is difficult to play, and it is difficult for gas turbines to have such a large power output, relying on ninjas to maintain it, it is too tiring.

Only the more mature steam power device in the ninja world can make it barely worth something, otherwise it is better to let the ninja go directly to it.

Another problem is that the resources of the Land of the Wind are quite abundant, and there is no shortage of various metal deposits, but the coal mines are not very abundant and not concentrated.

In short, there are a lot of problems, but this project plan still looks like that, and it doesn't hurt to give it a try.

After writing the opinion, Daimaru handed it to the face armor.

The long-awaited leader of the Northern Fortress bit his finger seal and cast a spiritistic spell to summon a leopard with a red half-dot body, put it in its mouth, and then let it leave with a reverse channel.

"Okay, this matter is over, don't pay attention to the next development, no one will bother you about it again! If you're all right, let's go back......"

"I take the liberty of asking, I don't know if I've been summoned back this time, I don't know what's important?"

"I don't know!"

The visor shook his head,

"I haven't heard anything wrong with the village lately, so it shouldn't be a bad thing......"

"That'...... All right! ”

Daimaru gave a salute, then retreated, and cast the shadow clone technique, asking the clone to inform his subordinates of his urgent departure, and then directly took off into the air, turning into a streamer and flying in the direction of Sand Hidden Village.

Half a day later, the dusty Daimaru saw the village hidden in the wind and sand.

"It's so windy today!"

After flying at high speed for a long time, Daimaru was also a little tired.

Because it was an emergency return, the defensive barrier that enveloped the village did not seem to open, and in order to avoid misunderstanding, Daimaru landed not far from the entrance of the village, and then walked over unhurriedly.

The first person who was on guard outside the door was startled when he saw a figure suddenly falling from the sky, and he was relieved when he saw that it was Daimaru.

"What a hassle!"

Omaru, who muttered a few words, put on his hood, and walked straight in the direction of the House of Kazekage.

I haven't arrived yet, but I'm running into Ai Luo, who is about to leave the village.

"Yo! I haven't seen you for a long time, and it's already a forbearance? ”

The taciturn little brother-in-law said hello and nodded to confirm Omaru's judgment.

"It's just in time! Where are you going? ”

"Garrison ...... of the Northern Fortress"

"I've been promoted, and I really have to go over there to brush up on my qualifications!"

Daimaru nodded knowingly,

"By the way, do you know why the village urgently grasped the recall?"

"It's too specific, I don't know, probably because of the air combat unit, I heard that Konoha Village sent someone over......"
