rock ninja log

At night, without the participation of Loess, Uehara and the others discussed the personnel arrangement for the night watch. Tugou and Uehara formed a team, one was the strongest reconnaissance ninja and the other was the most salty cannon fodder. This was done to balance the combat power.

Match.

"About what happened during the day, I'm sorry, Uehara." Tugou had planned to apologize, but he couldn't say it. He hesitated for a long time before finally making up his mind.

"About the apology... you get up first." Looking at Yiju who refused to get up for a long time, Uehara tried to pull him up but failed.

"As long as you apologize, we're settled." Uehara pulled him hard again and finally pulled the native dog up.

Taking the hot tea handed over by Uehara and taking a sip, the native dog said hesitantly: "Uehara, am I annoying? I often..."

"No." Uehara smiled and shook his head, "I once had a friend, his name was Spider Maru." As he spoke, Uehara looked at the burning bonfire in a nostalgic daze, "In the beginning, this guy was very annoying and looked down upon.

Weak people don't care about their companions, but then..."

"Later, he died?" After another sip of tea, the talkative native dog took the initiative to chat. He carefully took over Uehara's words.

"Fuck you!" Uehara almost couldn't help but get angry again, even though he knew this guy didn't mean any harm at all.

"You bastard bitch!" He slapped the bitch on the back with a slap, "Don't talk if you don't know how to speak. Do you know that you will get beaten if you talk like this!"

"But speaking of it," Uehara stared at Touga's evasive eyes from behind the mask with amusement, "I think it may have something to do with the nature of your ANBU work. ANBU guys seem to have very low emotional intelligence, and Toya is the same...

…”

…

After the words were spoken, there was nothing sordid. Uehara and Togo returned to the tacit understanding that ninjas can easily form, guarding one on the left and the other on the right.

Being on duty at night is boring, and you can't speak loudly, and you don't have any novels to read, so you have to be alert enough. Fortunately, there are not so many big trees that cover the sky and the sun in the Earth Kingdom, so the starry sky at night is just right.

"There is no Yinghuo star," Uehara counted the stars one by one with great enthusiasm. "There is no Cowherd and Weaver Girl either. The Cowherd and Weaver Girl are..."

"That's awesome!" After searching for a long time but not finding the Cowherd and the Weaver Girl, Uehara cursed in his heart, this weird world, even the stars are weird.

There was a slight sound of metal clashing in his ears. Uehara looked back and saw that the native dog was quietly setting up a trap or something like that.

"There are enough traps, native dog," Uehara was puzzled, "Did you find any flaws?"

"There are indeed some places that are not covered." He nodded and looked into the distance. Under the weak light of the campfire, a faint cold light could be seen in the open space in the distance. This was the reflection of the shuriken.

of light.

"Do you have anything that can be used to set up traps, Uehara." He touched his backpack and found that it was empty. Only then did he remember that Uehara seemed to have a lot of messy things in his scroll.

"If you want to set a trap, there is one. Let me look for it." Nodding, Uehara pulled out a scroll and took out a lot of things with a bang.

"Wire shurikens, barbs, animal traps, and other things." Uehara dug out a pile of things and handed them to the native dog.

Then, as if he suddenly remembered something, Uehara scratched his head, "There are too many things, I almost forgot these..."

There was a bang sound, which was the sound of another scroll being opened. Uehara took out a bunch of square boxes and said, "This is the finished trap." He opened a box, revealing the exquisitely crafted gear chains and various trigger mechanisms inside.

And the Senbon placed on it. Such a complicated thing was not made by Uehara. He spent a lot of money to have the parts made by specialized ninjas in the village, and finally assembled it himself.

"The method is very simple, just dig a hole and bury the trap," Uehara said, pointing to the scale line on the box to show the dog, "This position will do. After burying it," there was a click, and Uehara put the trap in.

A wooden board was placed on top of the box. "This lid has been processed to suit the environment of our Earth Kingdom, so it is made of a mixture of earthy yellow, gray and light green..."

Seeing that the native dog looked interested but not very understanding at the same time, Uehara kindly explained to him, "This color is difficult to detect after being camouflaged."

"But Uehara," Tugou expressed his doubts, "if the other party has reconnaissance or sensing ninjas, this exact same trap can be easily destroyed..."

"I have thought of what you have thought of." Uehara nodded, "The most hateful ones are the Hyuga ninjas. Any trap is useless to them."

"So I made this kind of trap, hehe, just to deceive people." He punched the trap cover with great force. In the horrified eyes of the native dog, nothing happened. He had just been

I saw that Uehara closed the lid after starting the machine.

"We have fought against the Hyuga guys, and they have a special characteristic in their battles," Uehara recalled carefully, "Hyuuga ninjas always appear on the battlefield as auxiliary forces. When they find traps, they often use shurikens to mark them.

The companions guide the direction, and the ninja who receives the prompt must either carefully avoid it. Or, instill chakra into the soles of his feet, and walk over lightly..."

"There is no way to avoid it, so my trap is aimed at the second situation." As he said that, Uehara gently let go of a box with a big face, lightly kicked it, and then quickly threw the whole thing away.

, not long after I threw it out, there was a bang and a cold light that even the local dog who was far away saw it.

"You see, I have adjusted the trap to be less flexible, otherwise it will activate as soon as I step on it." Uehara handed all the trap boxes to the native dog, "This trap is very sensitive.

The weight of the rabbit will trigger the trap if it falls on it, but the key factor of the engine is the landing point rather than the strength..."

Uehara couldn't stop talking about something he was good at, and he talked a lot. The native dog shook his head and left. Uehara's mouth grew, opened, and closed again.

Mathematics is a great subject. Even in a fantasy world, it still plays a vital role, because no matter in which world, as long as one plus one still equals two, then the principles of general theory can be used, calculus can be used, and mathematical construction

Models are more useful. In ancient wars, both East and West had some basic tactical patterns. For example, the basic defensive formation was a circular formation, and the basic offensive formation was a square formation. If this is the original answer, his answer is

——The reason why a circular formation is used for defense is because for the same area, the circumference of a circle is the shortest. This means that using a circular formation to defend requires fewer directions to defend, and at the same time, the density of one's own people within each distance

Larger, naturally more conducive to defense. The attack uses a square formation, because on a plane, a soldier of the attacking enemy may have to face a whole row of swords and spears of one's own side, which is a problem for everyone.

Nightmare...

After countless experiments on how to make the trap trigger based on the size of the contact area instead of force, Uehara finally came up with a way. The square trap cover was accurately divided into 20 x 20 four hundred points, and each point was linked by a lever.

Uehara has done experiments. When a rabbit steps on a trap, if it is divided into one foot landing, two feet landing, all the body landing, etc., the average number is 17 landing points. For canines, it is 12, and for bears, it is 12.

The largest creature in the class is 21, and the landing point of humans is more complicated. People of different age groups have different foot sizes. In order to get accurate data, Uehara and Tuba made statistics for a long time, and finally got the approximate value.

.

Based on the average age of twelve to the average of eighteen. The reason for these two values ​​is because 99% of ninjas on the battlefield are older than twelve years old. After all, younger ninjas are

It is a minority, and by the age of 18, most people's footsteps have been fixed, so the average is 23 trigger points...

Uehara didn't tell anyone about the finished product. He tried it secretly on his own. He once buried a trap without ninja tools at the entrance of the village. In one day, 623 people passed by and triggered the trap, including ninjas.

There were 410 people, and only 11 people failed to trigger the trap. The children passing by did not trigger the trap. Some of the large psychic beasts of some ninjas. For example, the psychic beast Uehara saw a guy was a big wild boar. After passing by, the trap was the same.

has not been triggered.

The success rate has reached over 99%, which shows that Uehara's idea of ​​making traps is correct. But let alone traps, it is just parts with a tolerance of no more than 0.1 mm that Uehara requires, and he is assigned an S-level mission.

After the commission is used up, you must know that the tolerance of 0.2 millimeters is already the standard for making the best quality shurikens.

"Uehara." Just as Uehara was racking his brains to think about how to improve the trap, the native dog came back after setting up the trap. "Do you still have the trap? There is still a gap."

"No." Uehara shook his head, "But you can try this." After saying that, Uehara threw a small barrel to the native dog.

"What is this?" The native dog tinkered for a long time without understanding what it was.

"The things I removed from the Ninja Umbrella can be put into Senbon. One is fine, and multiple are also fine." Uehara took out another cylinder and showed it to Tugou, and he gently twisted the bottom of the cylinder.

, and then pressed it again, and a Qianben flew out with a whoosh.

"I call this thing - anti-infantry mine." Uehara chuckled, "Although it is small in power, it is also very small in size and can easily be ignored. It is perfect for pricking the enemy's soles..."

The native dog once again left with a bunch of small black cylinders given by Uehara. Damn it, is the trap really lethal enough without detonating charms?
