The Wind Demon clan has amazing mobile phone sword skills, and Uehara has always wanted to learn it, and now he finally has a chance.

"The center of gravity of the kunai is forward, so if you take the kunai blade instead of the kunai handle upside down," said Kazega, taking out a kunai from the ninja bag, and then glanced at the position of the target, his arm was forced, and the kunai was nailed to the target with a whoosh, "See?" Uehara squad leader, so the power of the shuriken will be greater, but ......"

"But it's not easy to manipulate." Uehara took Fengjia's words, he just followed Fengjia's advice and took kunai to shoot at distant targets, Uehara's shuriken skills were decent, but the hit rate was very good, but he shot twice with the shuriken, and all missed the target.

"Yes, it's hard to maneuver, so you need to train harder." Fengjia nodded.

"I can do the training or something on my own in the future," Uehara, who was taking a small notebook to write something, glanced up at Feng Jia, and continued to bow his head and write quickly, about the Shuriken Chapter, he prepared a separate notebook.

"Okay." Feng Jia couldn't say anything about Uehara, he nodded, and took out a stack of quadrangular darts, "This kind of forbearance is more complicated to use, but the attack methods are diverse, you can attack in a straight line or in an arc, the main point is ......"

……

Every day starts in the morning and ends in the evening, Uehara and Fengjia spend time in training, throwing shuriken thousands of times a day, and at the end of each training, Uehara can barely hold chopsticks, but Fengjia has nothing to do, this level of shuriken training, he can complete it at the age of eight.

Han's armor was repaired at some point, and Uehara hurried to learn the skills of shuriken, and Kazuka gave him everything he knew.

When his physical strength was exhausted, he learned shuriken, and then Uehara bought a bunch of balloon balls and began to learn the long-delayed ninjutsu of Spiral Pill, and when the chakra was consumed, he began to learn shuriken again, and so on, time passed quickly.

Day 7. "There are two kinds of Wind Demon shuriken, one is the Shadow Windmill." Saying that, Fengjia handed Uehara a huge folded shuriken, which Uehara recognized, in the original book, Kakashiban was never slashed, and Sasuke used this kind of shuriken.

"This kind of arc-shaped attack ninja tool, you definitely don't like Uehara squad leader. As for the second type, "Feng Jia unravels the huge wind demon shuriken behind him," this kind of cross dart's wind demon shuriken, its attack method ...... - Double Butterfly Kill! ”

This is the most powerful shuriken technique of the Wind Clan, a huge wind demon shuriken in one hand accelerates with the help of running and spinning, and then when the speed reaches the fastest, it is thrown out one after the other with a whoosh, and the huge kinetic energy can collapse the earth flow wall.

A boom collapsed a layer of earth flow wall, the shuriken in front of it was inexhaustible, and it was nailed to the second earth flow wall with a bang, and then the shuriken in the rear arrived, and it accurately hit the tail of the previous wind demon shuriken, and the second earth flow wall also collapsed, and the third earth flow wall was also smashed out of a deep pit by the shuriken.

"That's amazing." Uehara's eyes shine, this huge kinetic energy is not something that can be resisted by simple physical skills.

"So, squad leader Uehara, there's only so much I can give you about shuriken, if you want to learn more, I can take you to my father......"

"No!" Uehara waved his hand to stop what Kazuka was about to say, and he shook the notes in his hand, "That's enough. ”

"Come, now, Fengjia, I'll help you train." Friends should help each other, this is the way to get along for a long time.

"Wait a minute, I'll take the things." The wind galloped away.

There are a lot of things that come from Fengjia, there are unedged shurikens, and full-body protective clothing similar to kendo halls, and a pair of very thick flat glasses, which are used to protect vulnerable eyes.

"It's about to start, Uehara." With four kunai in one hand, Feng Jia saw that Uehara was ready, and he said hello and was about to attack.

"Come on!" A kunai tried the feel in his hand, and Uehara rushed to attack in front of Feng Jia, and the shuriken technique was not as good as Feng Jia, so it would disrupt his rhythm.

"- Double Butterfly Kill!"

"Damn!" Seeing that he was directly knocked into the air demon shuriken like an ant, Uehara gave a middle finger to the wind and raised his middle finger speechlessly, and when he came up, he magnified the move, is there such a thing?

Uehara is very obscene, this is the evaluation that the more obscene Raizo gave to Uehara, after throwing a dozen shuriken, each shuriken was accurately shot down by Fengjia's shuriken, and Uehara no longer refused to shoot with Fengjia with a shuriken.

It takes all your strength to achieve the results of your training, so Uehara decided to give it her all......

"Hello ......" Feng Jia was about to throw the shuriken at Uehara's back, when suddenly there was a sneeze, his hand trembled, the shuriken was deflected, and he failed to hit Uehara, and the opportunity he finally caught was wasted.

"Bastard Uehara! Hello......" Kazega pointed to Uehara, who ran behind a big tree and hid his head and tail, "You're using chili powder again!" ”

"What's wrong with chili powder," Uehara removed his gas mask, it was too suffocating to carry this thing, "Old man Toba has to wait until he goes to the battlefield to give me poison, otherwise if I use poison, you are not a medical ninja, then ...... You're dead! ”

At halftime, Uehara followed Fengjia and counted one white dot after another, and the white dot was the record of both sides.

"Seven in my throat, two on my gas mask, four in my heart, one in my abdomen, and two in my back...... Well, close to the heart. Amazing, all fatal wounds! Asahaka stretched out his thumb, Uehara admired this guy a little, and it was remarkable to accurately get a hit to the throat and other vulnerable parts in high-speed movement, at least Uehara couldn't do it.

"How many times did I hit?" Uehara looked at the record made by Kazuka, "Twice? ”

"Three times." Feng Jia pointed to his shoe, and sure enough, there was a small white dot there, "There is a shuriken that you threw off, smashed into a branch and bounced off, and landed on my feet, and the other two, one is the right arm, and the other is the abdomen." ”

The results were too embarrassing, and Uehara's mouth opened and opened, and he was embarrassed to discuss the results again.

It is a good habit to sit face to face and take out a note, and a detailed summary is better than ten blind and aimless trainings.

Uehara was inspired by the goggles used for training, and he felt that gas masks could also be made of better materials, providing the necessary protection like visor.

"Where are these things recorded...... Uehara pondered for a moment, took out a new notebook, and then swiped and wrote a few big characters of "Notes on the Development and Improvement of Ninja Equipment".

"Uehara, I think my hair is too much of a problem," Remembering to remember, Fuga suddenly said something that broke the peace.

"What?" Uehara didn't react for a moment.

"It's hair," Feng Jia pointed to his long hair, "if it's too long, it's easy to interfere with the vision." ”

"Then cut it, do you need help?"

"No, you don't." Fengjia shook his head.

"Uehara, you still have problems with your dodging ability, and these parts of your throat need to be well protected." Attacked Uehara's throat seven times, but the dazzling battle was not at all happy.

"Speaking of which," Uehara frowned slightly, then reached to the back of his neck with his hand and moved slightly, and then clicked, and a ring of iron was unraveled.

"This is to prevent throat cutting, if anyone wants to kill Uncle Ben secretly, hehe, I'll ......"

"Does it work?" Feng Jia looked at the iron piece that had been disguised and was very curious, the camouflage was the same color as the skin, no wonder he didn't see it when he was training just now.

"It's useful," Uehara nodded, "I've done experiments, and if you don't use a chakra attachment weapon, and the force is not too strong, it can provide enough protection." As he spoke, Uehara paused, "But if the enemy's weapon is attached to the chakra, then it can't be resisted," as he spoke, Uehara took out a handful of kunai with an open blade and poured some chakra, just lightly, the iron piece was punctured, and at the same time there was a crisp hissing sound of steel rubbing, "The iron piece of this material we chose is very tough, and it will make this kind of chirp when attacked, compared to dying silently, so that it can remind other companions and make them have enough preparation, It won't be killed by sneak attacks one after another. ”

Feng Jia was silent for a long time, "This material," he kept folding the iron piece until the iron piece was finally deformed and twisted, and it could not be restored, "in fact, it can be changed to another material." ”

Uehara nodded, noncommittal, the Wind Demon clan has some special alloys, which Uehara has known for a long time.

"And this," Uehara untied his necklace, "this broken whistle is called an owl, don't worry about it, this thing." ”

Uehara pointed to a pacifier-like gadget to show Kazuka, "Many of us Iwa Shinobi can't swim, and it's good to have chakras here when they tread water, but chakras always run out, so I made this thing." ”

Uehara explained in detail to Feng Jia, "If you don't fall into the water, you can't swim, and you can use this underwater breath to hold on to the water for more than ten minutes." ”

"Really?" Fengjia glanced at Uehara suspiciously.

"You can try."

Feng Jia really brought a large basin of water, bit the respirator and plunged into the water, and waited for more than ten minutes before he couldn't hold on, and came up panting.

"Really."

"Oxygen is slightly soluble in water, the oxygen content in the water is small, ten minutes is the limit, in fact, you can get some oxygen cylinders and other things, but it is too difficult." Uehara handed the respirator to Fengjia, "I'll give you this one, I'll go back and make another one." ”

"How do you know that?" Taking the respirator and placing it carefully, Feng Jia looked at Uehara curiously.

"The gas molecules are much smaller than the droplets, so as long as the pores of the material are larger than the gas molecules and smaller than the droplets, the gas and water can be separated......"

"No," Kazega interrupted Uehara, "I mean, where did you get this thing?" ”

"The old man of Toba planted a lot of plants, I am learning medical ninjutsu from him, many plant tissues have a dense film that can reach the nano level, I took a little bit of each plant for experiments," remembering the medicine of Tuba seeds, but was chased and beaten, Uehara felt that the study of medical ninjutsu was too miserable, "There are more than 300 kinds of plants, and there are seven kinds of respirators, three of which do not have large tissue membranes, two kinds of breathable membranes are too thin and easy to break, and one is toxic, and I will find such a suitable one." ”

"I didn't ask you this," Feng Jia still pestered Uehara, "I mean, where did you get this knowledge?" ”

"That's it......" Uehara smiled, a little weirdly, "I saw it when I watched Man and Nature." ”
