"The first test of rocket launcher propellant fuel, start now." Kenichi Amamiya stood on the plain, he squinted ahead, there was a forest there, but he couldn't see it anymore.

After all, the position where he is standing now is still about ten kilometers away from the woods, and this distance is impossible to see even by the writing wheel, and it is naturally impossible to kill the trees in the woods from a distance of eight hundred miles.

"However, this distance is a good choice for testing the launch speed and distance of the rocket, although the range of ten kilometers is very short, but it is basically enough." Ken Amamiya weighed the rockets in his hand.

Kenichi Amamiya made a metal cylindrical rocket, which is similar to a conventional rocket, and the front is also pointed, which can reduce wind resistance, increase the speed of rocket launches, and increase a certain range.

But the rocket thing, because Kenichi Amamiya requires it to strike fast, so if the range is too far, it can be hit remotely, but the problem is that the fuel requirements are very high.

After all, Kenichi Amamiya still needs a weapon with a fast enough rate of fire, so that it can form an effective blow to the ninjas, otherwise the rate of fire is too slow, and it will be discovered by the ninjas before it flies over, and then a group of ninjas run away, so what is the significance of this rocket launcher?

"And frankly speaking, the range of ten kilometers is not short, after all, the effective range of most bazookas is not very high, and this thing is more designed according to the requirements of the Katyusha rocket car." Amamiya Kenichi naturally didn't plan to make a bazooka, the range of that thing was relatively limited, or the rocket car was more in line with his requirements.

"But it still feels a little rough to the touch." Kenichi Amamiya touched the rocket in his hand, and the rocket was very smooth and cold to the touch, just like a superb beauty.

But this

It's like touching an abrasive cloth, and there are some places where the roughness is very noticeable.

The production of this thing is relatively rough, but it is finally made, the industrial level of the ninja world is really bad, it seems that there is time to study an assembly line production factory, even if it doesn't work, you have to make a machine tool that can be Seiko or something.

Otherwise, a lot of things don't work very well to make.

However, the things that Seiko needs are not as difficult as ordinary.

"Then that's the position, according to the parabola of the rocket, I just need it." Kenichi Amamiya adjusted the position of the bazooka on his shoulder, and then pressed the launch button.

There was a roar in an instant, followed by a strong recoil, but for Amamiya Kenichi's current physique, this recoil was not a problem, and he carried it easily.

"One second, two seconds" Amamiya Ken began to count silently in his heart after pressing the launch, he wanted to see how long it would take from launch to explosion, although ten kilometers was a long distance, but Amamiya Kenichi also reserved a shadow clone over there, just to monitor a landing point and flight time of the rocket.

About twenty-two seconds later, a feeling of dizziness came from Amamiya Kenichi's brain, Amamiya Kenichi frowned slightly, he now knows the location and time of the rocket.

"Although it did not deviate from the target position, it did not fall into the forest, but landed in front of the forest, which means that the effective range of the rocket loaded with this chemical fuel is less than 10 kilometers." Kenichi Amamiya was thoughtful.

Moreover, the total time from launch to explosion is twenty seconds, and it also takes a little time for the shadow clone to be disarmed, so this time loss needs to be calculated.

"Let's take a look at a specific explosion site, and then estimate the distance of the launch, but it seems that the calculation of this parabola is not particularly accurate, is it due to air resistance?" Kenichi Amamiya ran briskly in the direction of the explosion while writing something on the paper with a pen.

The parabola is a mathematical model calculated by Kenichi Amamiya himself, and it can be used to estimate an approximate landing point of a rocket and the angle it needs, etc.

Normally, rocket cars are calculated and adjusted in an instant through computer commands, but Amamiya Kenichi's thing is still in the experimental stage, so he is still hand-adjusted.

"Although I had already included these things in the calculation at that time, such things as air resistance, wind resistance, etc., it was obviously more complicated to use in practice." Kenichi Amamiya also saw the center of the breaking point.

A very large crater, 500 meters from the center of the explosion point, also found shrapnel, embedded in the soil, it seems that the lethality of this thing is quite good.

Pure mathematical models are very idealistic, and even if various parameters are added, they may not be perfectly reproduced, after all, there are all kinds of differences in reality, so it is necessary to design some lead time to tolerate errors.

"It's basically impossible for a normal rocket to reach such a large crater, is it really because of the chakra?" Kenichi Amamiya was a little excited.

The integration of chakra not only reduces the requirement for explosive yield, but also increases the power of the explosion, and the current rocket is a weapon that can change the pattern of rocket artillery in the previous life.

After all, this thing is really powerful.

"The actual range, no, it should be said that the range this time is 9348 meters?" Kenichi Amamiya also calculated the location of the center of the explosion point and the forest, and then he stretched out his hand to feel the current wind speed and direction, and then put his hand down.

It's windy in Snow Country, but it's not very windy today, like a summer breeze, so if the weather is a little worse, the range of the rockets will be lower.

"Twenty-two seconds to cross this distance, that is, a rate of fire of four hundred and twenty-five meters per second?" Amamiya Ken recorded this number, and then recalled the memories of the shadow clone before.

"The speed is still a little slower, if the enemy notices, it's still okay to dodge, you can consider improving the rate of fire and explosion power." Kenkazu Amamiya recorded the advantages and disadvantages.

According to the movement speed of the ninjas, this speed is fast, but after all, it is still easy to detect from a distance, so you need to increase the rate of fire.

The faster the rate of fire, the less time is given to the enemy to react, and the more powerful the explosion, the greater the damage range, so that even if the enemy discovers the presence of the rocket, it will not be easy to escape.

"As for these two problems, we can probably try to solve them by improving the ratio of chemical fuels, propellants, and explosives in rockets." Kenichi Amamiya walked back to his lab, and he had some new ideas.

"But the explosives exploded, I remember" Kenichi Amamiya flipped through his experiment logs in the laboratory, and there were a lot of his experiment logs, but most of them were placed in the test base of Tanokuni, and there were only the latest experimental logs here, so it wasn't too complicated to find.

Research and Summary on Kaleidoscope Writing Wheel Eyes

Study on the Fusion of Trinitrotoluene and Fire Chakra

Amamiya Kenichi's hand paused, and then pulled out a copy of "Research on the Fusion of Trinitrotoluene and Composite Attribute Chakra" from it, and then opened it and looked at it.

This is an experiment log written by Kenichi Amamiya when he was studying what effects will be achieved after the fusion of trinitrotoluene and chakra with various properties, and it records many of his attempts.

【. After trying to fuse the fire attribute and wind attribute into trinitrotoluene, the power of the explosion increased significantly, which was in stark contrast to the fusion of water and fire.

Kenichi Amamiya touched his chin, and during this period of research on trinitrotoluene, Kenichi Amamiya discovered a new problem, that is, sometimes not all the attributes of chakra are instilled into it to achieve the best results.

For example, after the fusion of the wind attribute and the fire attribute chakra, the power of the explosive will be significantly increased, while the fusion of the fire attribute and the water attribute will cause the explosion to decrease in range and weaken.

However, when the ratio is adjusted to the ratio of fire attribute 7 and water attribute 3, a stream of high-temperature water vapor will be formed when it explodes, which is equivalent to the damage of burns, but it does not have much significance.

"Wind, fire and thunder, these three attributes are the best results of the rocket explosives after many experiments." Kenichi Amamiya has found a way to increase the power of the explosion, but now there is another problem with propellants, which can only be tried slowly.

However, Kenichi Amamiya still plans to use today's propellant formula first, for no other reason, mainly because there are not many raw materials, he plans to try to make a Katyusha rocket car first, and then complete his side quest and get the reward.

The production of the rocket car is simple, although Amamiya Kenichi did not plan to make a truck directly, but it is still possible to simply weld these bazookas side by side, with sufficient raw materials and the support of the personnel arranged by Fenghua Xiaoxue, Amamiya Kenichi quickly made a six-by-six abbreviated artillery array.

"Well, there is no problem with the control of the upper and lower amplitudes, and the next thing is to test the speed and interval of the launch, as well as the accuracy, if there is no problem, then you can fight in real combat." Kenichi Amamiya was very satisfied, and there were still a lot of rockets beside him.

These are all rockets made by Kenichi Amamiya with the attribute fusion of wind and fire thunder, but in order to increase the power, Kenichi Amamiya also added a little more TNT explosives, of course, this is also related to the requirements of attribute fusion.

If you want to make TNT that can fuse the three attributes of wind, fire and thunder, then you need to add more explosives, otherwise it will not be able to hold it and there will be an explosion.

This time it needs to be tested as well, but at the location of the test.

"Huh?" Amamiya Ken glanced at his ring, and began to heat up again, Nagato looking for himself?

Amamiya Ken was stunned for a moment, he thought of what Nagato said before, so now is it time to give himself a task? It didn't matter if Kenichi Amamiya wanted to get in touch with Nagato.

"Chief, you're looking for me." Amamiya Ken directly released the thought wave and went in, but as soon as he entered, he was stunned for a moment, because he saw that Nagato was not the only one in the space at this moment.

There was still a person standing next to Nagato, it was Xiao Nan.

Amamiya Kenichi breathed a sigh of relief, fortunately it was Xiao Nan, not Heijue, otherwise it would be really troublesome to talk about things.

"There's a mission for you." Nagato opened his mouth bluntly, without waiting for Amamiya Kenyi to say, Amamiya Kenichi didn't say anything when he saw this, he also wanted to see what task Nagato planned to give him.

"Yanyin Village has issued an attack mission on Shayin Village, and you have been named." Nagato continued, and Amamiya Kenichi was stunned for a moment, good guy, what does Iwakuin Village want to do? And specifically named yourself?

"No, how can you have the feeling that I am a cowherd when you talk like you?" Amamiya Kenichi couldn't help but complain, Xiao Nan on the side laughed out loud, Nagato also paused, and then Amamiya Kenichi looked at Nagato and took a deep breath, clenched his fists and calmed down.

Nagato regretted it a little, if it weren't for not wanting to make a special case for the Akatsuki organization, he really didn't want to give a task to Kenichi Amamiya.

"Anyway, you remember to complete the task, the requirement of Yanyin Village is to attack Shayin Village, and then cause effective damage, and the reward is 100 million taels." Nagato held back the emotions in his heart and continued.

Amamiya Xian nodded, 100 million, he would never take it before it was replaced, after all, the cost is uneven, but it doesn't matter now, just need to cause enough damage, then you can just try the cluster strike capability of rocket artillery.

"Okay, I see." Kenichi Amamiya took it, although the remuneration for this task is not good, it is not bad, and the main thing is that the cost can be amortized, so it is enough.

And Kenichi Amamiya also needs a place to test his rocket artillery, and now it seems that Sand Hidden Village is the first unlucky guy.

The only trouble is the existence of the defensive enchantment, and I don't know if the rocket artillery cluster can break through the defensive enchantment, but the small place of Sand Hidden Village is relatively poor, and the strength of the ninjas is relatively weak, so it shouldn't be a big problem, right?

"That" Nagato plans to kick Kenichi Amamiya out directly, after all, this guy is too troublesome.

"Chief, what do you think of my previous proposal?" Kenichi Amamiya spoke, and Nagato also paused, he was silent for a moment, and then glanced at Kenichi Amamiya.

Amamiya Kenichi looked at Nagato's appearance, and he was happy, there is a play.

"If the concept and boundaries of the village and the state are not erased, then the war will only recur." Kenichi Amamiya said very sure, if the ninja world can't be unified now, peace is just an illusion.

"Then erase these things." Nagato disconnected from contact, and if he continued to listen, Nagato felt that his heart would really be more entangled, which was really too painful.
