rock ninja log

(——This chapter is a duplicate chapter. It was published twice when it was about 3,000 words. I will get up early tomorrow to revise it. I have been working overtime and am exhausted. Sorry, I will update a free chapter on Sunday, please forgive me!!)

"No, this is it." Uehara rummaged through his pile of scrolls and miscellaneous items for a long time, and finally found the ninja tool he made when he was in the Ninja Tool R&D Department.

A strange square box, is this the so-called powerful ninja tool? Xie frowned, his eyes full of doubts.

"This is one of my most proud ninja tools, Scorpion." Uehara did not feel ashamed at all about the simple and excessive trap.

"This is a modular trap, in other words a finished product trap."

"Trap?" Scorpion's voice rose a few degrees, and he was extremely surprised. Originally, he thought that the simple box Uehara took out was the carrier of a terrifying ninja tool.

"That's right, it's a trap." Uehara continued to explain, "Even for earth escape ninjas who are good at setting up traps, when enough traps need to be set up, the consumption of chakra is still huge."

"So, I made these standard trap modules."

Afterwards, Uehara began to explain the various advantages of his trap to Scorpion in detail.

For example, the modular design can be combined with trap boxes into different shapes according to the terrain, and the terrain applicability is excellent.

The camouflage on the trap is also designed with different replaceable parts based on the possible encounters in rocky areas such as rainforests, deserts, etc.

As for the concealed weapon excitation device, metal and non-metal materials are available, and watertight and non-watertight materials are available.

There are countless other advantages. In short, this is a well-made and cleverly conceived ninja tool, but it is expensive and extremely weak in lethality. It can probably only serve as an assistant or cause trouble for genin-level ninjas.

"Scorpion, my trap does not require human effort or ninjutsu to activate, but it is more threatening to ninjas than ordinary traps."

"Moreover, it can be triggered only for ninjas, relying entirely on mechanical power. This is what you want to know, and it belongs to the wisdom of the "puppet"."

Uehara said that his traps had their own "wisdom", and Xia wanted to find out.

Later, Uehara took Xie to a secluded training ground to demonstrate it to him.

Setting up the trap is very simple. Uehara only needs to dig a hole, and then place the trap box inside. A trap above the passing line that is enough to emit hidden weapon poisonous mist or detonating talisman is completed. Judging from the time taken and the effect achieved,

Uehara's trap is not useless.

In the first test, the scorpion found a rabbit and drove the little rabbit to trigger the trap. However, the little rabbit jumped over the trap and the trap still did not trigger.

"Is it the weight?" Xie frowned and thought. The competition of wisdom and the exchange of knowledge between puppet masters fascinated him.

The reason why the little white rabbit failed to trigger the trap the first time, the scorpion thought it was because it was underweight and failed to reach the minimum limit for triggering the trap.

The second time, Xie Shang frantically brought a big stone and hit it on the trap with a thud, but the trap still did not trigger.

"Did it get smashed?" Xie was very doubtful about the quality of Uehara's trap.

It wasn't until Uehara confirmed again and again that his trap was intact that Xion decided to continue trying.

Scorpion, who has a very inquiring spirit, had chakra attached to his soles before he was not sure whether the trap could activate hidden weapons. He wanted to skip the trap like a light fallen leaf.

However, as soon as he stepped on the trap's camouflage cover with his soles, there was a clicking sound, and the trap's camouflage cover immediately parted, a silver light flashed past with a buzzing sound, and Scorpion immediately stood up and jumped to avoid it.

"really weird."

Doesn't the triggering method of the puppet rely on weight? What could it be?

Scorpion reloaded the hidden weapons of the trap and put all the mechanisms back into place with Uehara's help.

This time, Scorpion didn't concentrate the chakra on his feet. He stepped on the trap casually, and the trap was triggered again.

Xie vaguely felt that he had captured the truth, and he waited quietly for Uehara to give the final answer.

"Scorpion, if it were you who wanted to make a trap triggering device, when would you most like to trigger it?" Uehara took out a screwdriver, pliers, wrench and other things, and asked while dismantling the trap.

"It's most suitable to trigger the trap when a living creature approaches it." Scorpion gave the easiest answer to think of.

"Are they just living creatures?" Uehara smiled, "Reptiles are just as much living creatures as frogs."

"Or, Scorpion, you would say that after someone steps on the trap, that is the best time to trigger the trap, right?"

"But there are differences between ninjas and ordinary people."

"Ordinary people cannot control their own weight, but ninjas can even walk on water using chakra."

"It is definitely not possible to rely solely on weight as the triggering condition of a trap. Using the weight of the human body to limit the triggering conditions of a trap can indeed filter out most of the accidental triggers caused by animals. But there are also many things that are heavier than the human body, such as

The enemy's psychic beast, or Earth Release Ninjutsu."

"Is it a chakra test paper?" Scorpion interrupted Uehara, "When the fire escape chakra encounters the chakra test paper, it will catch fire, the wind escape will split from the middle, the thunder escape will become wrinkled, the water will be wet, and the soil will become broken.

"

"If the chakra test paper is used as the triggering device of the trap, as long as chakra touches the trap, the state of the chakra test paper will change no matter what, right?"

"In this way, can we complete the traps triggered by ninjas without relying on ninjutsu and human control?" Xie was very excited. The communication with Uehara was always as fun as solving puzzles one after another.

This feeling was the same as when Scorpio got the password-locked materials from his grandma, but it was just not as interesting as Uehara.

"Use chakra test paper, well, that's a good thing to note." Uehara was stunned for a moment, "But the chakra test paper is not strong enough to serve as a concealed weapon stimulating device."

"Also, Scorpion. How can a ninja trigger your trap if he doesn't use chakra to pass through it?"

It is not difficult to design a trap that can be triggered when a ninja passes by. You can even tie a rope. The difficulty is that the prerequisite is not to be trapped by a light rabbit or a heavy rock or a psychic.

The beast triggered the trap.

A trap that couldn't be simpler, but upon closer inspection, Scorpio finds that there are many issues to consider.

"Scorpion, let me tell you the answer -" Uehara revealed the final answer, "As a better distinguishing mark to distinguish ninjas from animals, it is not the weight, but the shape."

"Shape?" Xia was confused.

"The shape of footsteps." Uehara fully demonstrated the precision machinery he designed to Xia, "I designed hundreds of sensitive contacts on the camouflage cover of the trap. Whenever it is touched, a certain number of

changes in contact points.”

"Things like rabbits or frogs have very few contacts."

"If something like a big rock hits the trap, there will be many contact points."

"With such a number of contacts close to the soles of human feet, it is almost certain that someone has touched a trap."

"This is not determined by chakra. Whether a ninja uses chakra or not, the gait will not change."

Although it’s useless, the design looks very subtle, doesn’t it?

"I have a question, what are the contact points of a human gait?" Sure enough, Scorpio was able to get to the crux of the question right away.

"The touch points triggered by gait are different for people of different ages."

"Because of genetics or other factors, people in different countries have different gaits."

"As for how many contact points there are, Scorpion, I won't tell you." Uehara looked like a thief.

"The contact points on the soles of children's feet are not much larger than those of frogs," Xia shook his head, "Uehara, your design has serious flaws."

"But, the number of children going to the battlefield is very small, isn't it?"

"If our trap can work on 95% of ninjas, it is enough as a simple trap."

"If all ninjas are taken as a whole, what is the average gait of 95% of ninjas? Scorpion, you have to calculate it yourself."

Uehara wants to guide Scorpio to think about the problem in another way, from a mathematical perspective.

Just like how useful a theory is on the battlefield, the personal experience of any legendary ninja is not enough to serve as a reference.

The only thing that can be used as a reference is to count the number of ninjas who died from the two types of ninja tools on all battlefields, and then the analysis based on other factors is valuable.

Iwagakure Village has never done anything like this. Although there is a very simple reason, changing the buttons on the ninja uniforms from metal to plastic when fighting Kumo ninja will definitely reduce casualties, just more or less, but no one

Have done this before.

After getting inspiration from Uehara's trap this time, Xiao felt that he should change his mind to make puppets in a different way. But what kind of method it was, Xiao was still confused for the moment.

With Uehara's Ninjutsu talent and little knowledge of Puppetry, he is not enough to teach Scorpion how to practice Ninjutsu. What Uehara can give Scorpion is another way of thinking about problems - rigorous

Data statistics and analysis supplement or even replace judgments based entirely on experience.

"No, this is it." Uehara rummaged through his pile of scrolls and miscellaneous items for a long time, and finally found the ninja tool he made when he was in the Ninja Tool R&D Department.

A strange square box, is this the so-called favorite ninja tool of someone? Xie frowned, his eyes full of doubts.

"This is one of my most proud ninja tools, Scorpion." Uehara didn't feel ashamed at all about the crude puppet.

"This is a modular trap, or a ready-made trap."

"Trap?" Scorpion's voice rose a few degrees, and he was extremely surprised. Originally, he thought that the simple box Uehara took out was the carrier of a terrifying ninja tool.

Uehara said that his trap could recognize ninjas and trigger them automatically. It was such an interesting thing that Xia wanted to explore.
