Red sand dust

Daimaru only looked through the seemingly thick pile of documents for a few minutes, glanced through them hastily, pulled out two of them, and threw the others into the trash can.

Seeing Daimaru's unceremonious behavior, Mask just smiled. It is not surprising that a young man who is quite talented and young and energetic would do something like this. At his age, Meng Jia was not much better than Daimaru.

Nowadays, Daimaru, who has made outstanding achievements, can be regarded as a celebrity among sand ninjas. Along with his famous name of "Red Sand", there are also his past dark histories that make people laugh.

It is already a great honor to throw some of the "hard-worked" funding-defrauding plans of some predecessors into the trash can instead of yelling at them.

"There are actually two that are still eye-catching?"

"Just so-so! It may not work, but the idea is very good. Even if it doesn't succeed, we should be able to verify some ideas and discover some valuable by-products..."

"I know that testing ideas is not always smooth sailing when it comes to Ninjutsu research..."

Even with the success of the air combat force, we cannot completely deny the several unsuccessful attempts in the past few decades. A man who is over 40 and has experienced a lot of experience will certainly not be without knowledge.

“What should I say, a valuable by-product?”

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

"It's like we were originally planning to develop a special medicine to treat coughs, but it turned out that it was of no use in treating coughs, but it was very effective in treating constipation..."

Daimaru's indecent analogy made Mask laugh:

"That's right! Sometimes some ridiculous discoveries are just like this that people didn't expect. Back then, the Nidaime tried to recreate the magnetic escape blood successor boundary from Ichibi Shukaku. Although it failed, the by-product was sand ninjutsu. It’s also very useful…”

"That's what I mean!"

Mask patted Daimaru on the shoulder and said:

"According to your ideas, if you have any opinions, feel free to ask..."

Daimaru nodded:

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

As he spoke, Daimaru carefully wrote down his opinions on two plans.

One of them is the "Submersible Mothership" that Daimaru barely likes.

The evaluation is: cautiously optimistic, and it is recommended to conduct wind tunnel and ship model experiments to optimize the line shape.

As for propellers, there was no need for Daimaru to teach them. A relatively simple steam-powered auxiliary propulsion system had been designed on the large submarine carrier.

Yes, there are steam-powered trains and steam paddle boats in the ninja world, and propeller boats are relatively rare.

Although the petroleum industry has not yet developed, and there is no trace of gasoline and diesel combustion turbines, due to the existence of ninjas, silly and thick steam engines have become more popular. Regardless of the background of the era, 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 flat-rotating propeller.

When Daimaru saw the drawing of this thing, his jaw almost dropped in surprise.

Because of the existence of chakra, the level of science and technology in the ninja world is indeed affected by the extraordinary power of ninjas, but the intelligence and imagination of ninjas are no worse than those of real scientists. Some of the fantastic ideas that are adapted to local conditions are really Daimaru was amazed.

After decades of development of puppetry, there are indeed many surprises that may seem "inconspicuous" but are very effective. Those experienced puppet masters have something in their stomachs.

Of course, Ikawa, who was very interested in Daimaru, did not want to design a battleship, but wanted to develop water combat puppets, so most of the designs were still driven by the ninja's chakra.

Another thing Daimaru found interesting was a miniature battle fortress with limited movement capabilities.

It carries a heavy ballista, a light fire network weapon system, and has very clear targets, such as anti-aircraft, siege, large psychic beasts and even tailed beasts.

The effect is not yet known, but the idea is still good.

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

If chakra is used to drive it, I don't know how many people will be required to use it. This thing is very difficult to play. It is difficult for a gas turbine to have such a large power output. It is too tiring to rely on ninjas to maintain it.

Only a relatively mature steam power device in the ninja world can make it barely valuable. Otherwise, it would be more effective to let the ninja directly perform ninjutsu.

Another difficulty is that the Kingdom of Wind is quite rich in resources and has no shortage of various metal mineral deposits, but the coal mines are not very rich and not concentrated.

In short, there are many problems, but this project plan still looks like that, so it doesn’t hurt to give it a try.

After writing his opinion, Daimaru handed it to Mask.

The commander of the northern fortress, who had been waiting for a long time, bit off the seal on his finger, used a psychic technique, summoned a leopard with red spots on its body, put it in its mouth, and then let it leave counter-psychically.

"Okay, that's it for now. Don't worry about what happens next. No one will bother you anymore! If you have nothing to do, just go back quickly..."

"I would like to ask, I don't know if I was called back urgently this time. What's the important matter?"

"I am not sure as well!"

Mask shook his head,

"I haven't heard of any problems in the village recently, so it shouldn't be a bad thing..."

"Oh well!"

Daimaru gave a salute, then retreated, used the shadow clone technique, and asked the clone to inform his subordinates about his urgent departure. Then he directly jumped into the sky, turned into a stream of light and flew towards the direction of Sunagakure Village.

A little while later, the dusty Daimaru saw the village hidden in the wind and sand.

"The wind is so strong today!" 』

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

Because it was an emergency return, the defensive barrier covering the village seemed not to be opened. In order to avoid misunderstanding, Daimaru landed not far from the entrance of the village, and then walked over slowly.

The guard who was on alert outside the door was startled when he saw a figure suddenly falling from the sky. He was relieved when he saw that it was Daimaru.

"It's really troublesome!"

Daimaru muttered something, put on his hood, and walked straight towards the Kazekage's house.

Before they arrived, they met Gaara who was about to leave the village.

"Hey! Long time no see. Are you already a Jonin?"

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

"It's quite timely! Where are you going?"

"Northern Fortress Garrison..."

"I've been promoted to Jonin, so I really have to go there to brush up my qualifications!"

Daimaru nodded understandingly,

"By the way, do you know why the village called me back urgently?"

"I don't know how specific it is. It's probably because of the air combat unit. I heard that Konoha Village sent people over..."
