"Hunting," Uehara looked at packing his bags and waved goodbye to Hunting and Mayi who saw him off, "Teacher Han and I will leave first, remember to tell Kazubushi not to let people throw stones into the yard......"

"Settle down!" Kari, who was in a wheelchair, was impatient, "I see! ”

Looking at the kite in the hand of the real cloth, it seems that the advice to hunt to recuperate from injuries did not listen to it at all, this guy, he didn't forget to play if his leg was injured.

The Wind Demon Clan's base is not in the village, but on the side of the Earth Country that is closer to the Land of Thunder. Han and Uehara went to the Wind Demon Clan, not to play, but to deal with something. Han's handsome steam armor was damaged by the Four Tails during the Tailed Beast Rebellion, and he needed to repair it with the help of the Wind Demons. Han's armor and the ability of the five tails can glide at low altitude, and the live ninja version of Iron Man makes Uehara envious.

Uehara had always wanted to disassemble the armor to see what the structure was, but Han was not at ease to hand it over to Uehara, especially after Uehara dismantled the large puppet captured from the wind shinobi into a pile of parts, and Han didn't believe what Uehara said could help transform the steam armor.

Sha Shinobi's mechanical puppet has given Uehara too many surprises, tight gears, chains, levers, as well as balance systems, hydraulic systems, etc., etc., showing a lot of mechanical design ability. Could it be that every puppeteer is a science and engineering graduate? Uehara thought strangely.

The ninja world does not have much developed transportation, ordinary people have horse-drawn carriages, boats powered by wooden oars, and ninjas have psychic beasts, and more often rely on a pair of feet to travel long distances, and the existence of chakra is not difficult to travel thousands of miles a day.

"Where did the owl go?" Han looked at the sky and saw no owl, and it was obviously still there when he first left the village. Han felt that Uehara had entered a misunderstanding with psychic beasts, and he had seen more than once that owls and Uehara were arguing and grabbing food, and psychic beasts that did not obey orders were prone to problems in battle.

"Owl," Uehara put his hand on his eye and looked around the sky, but there was no sign of it, then he took off the binoculars on his waist and looked at them for a while, but there was still no owl in sight.

Uehara has a broken iron whistle, and the sound is hard to hear, but this is the only one that Uehara has made so many whistles. The three elements of sound are, timbre, audio, and volume. Timbre depends on which instrument is being vocalized, volume is the amount of energy of the sound, and audio, the frequency of the sound, in Hz, is inversely correlated with the wavelength of the sound wave. This tin whistle in Uehara can be heard very clearly at a long distance, and it can be heard very clearly at a very close distance, but it is not so clear in places that are not so close and not so far away. How to make a spoon that emits short frequencies and long sound waves, Uehara had no choice but to make a bunch of random ones, the data is large enough, the data will fluctuate in a certain range, and one or two suitable ones can always be picked out. I heard from the physics teacher that when the new republic wanted to make the atomic bomb, it could not make enough accurate parts because of the backwardness of the machinery, such as the parts with an accuracy of 0.01, and the machines of New China could only make 0.1 parts. Qian Xuesen's predecessors, who returned from studying abroad, gave a solution - make 10,000 of each part! There were enough of them, the error was always hovering around the accurate value, and only one or two suitable parts could be selected for making 10,000 parts, and it was in this extremely difficult environment that the atomic bomb was born.

A whistle, a piercing sound, the owl that disappeared into the clouds obviously heard it, and as soon as the whistle fell, a black dot gradually grew larger, and it was about to fall on Uehara's shoulder in the blink of an eye.

"Stop!" Before the owl fell, Uehara hurriedly staggered to dodge, and the owl's talons Uehara put an iron claw on him, which was very sharp, and there was a blood mark hanging on it, if he let it scratch it, it would be okay.

"Where's the other claw?" The owl still landed on Uehara's shoulder, but fortunately, it knew how to fall gently, otherwise Uehara would have to hang the lottery again.

"It's gone! The claw is off! Dropped off! The owl didn't like the feeling of being cumbersome in its talons, so it shook it vigorously twice, and the other one fell off.

"Okay," Uehara didn't plan to pick it up, "let's go to the Wind Demon Clan this time, and let Fengjia help you make a more suitable one." ”

Creating a claw that provides protection without compromising flexibility requires a lot of ingenuity, which Uehara doesn't have.

"Eat fish, eat fish!" The owl flapped its wings and asked Uehara to grill fish for him, but since eating the grilled fish, the owl would never eat raw fish again, and the devil knows why owls have the same taste as humans.

"If you eat fish, catch it yourself!" Uehara drove the owl away after a series of bombardments, and finally sent the owl away.

The eagle can fly at a speed of more than 120 kilometers an hour, and if nothing else, the owl will return after half an hour, and will bring back a cage of fish. In order to make it easier for the free-range owls to eat, Uehara made him a fish cage made of very thin bamboo strips, which can hold more than a dozen fish at a time.

"Teacher Han, what do you want to eat?" The stove was set up in minutes, and Uehara began to cook. It's good to have gas, it's too wasteful to use alcohol all the time.

Taking the towel that Uehara handed over to wipe his face, and sitting on a stool with a table and a parasol, and a few glasses of juice with different flavors on the table, Hanyou thought to himself that ninjas shouldn't spend too much time enjoying themselves. But after such a long journey, Han's mouth was already dry, and after drinking the cold apple juice, he shut up.

The sun umbrella shaded the sun, it was cool under the umbrella, drinking juice and looking at the busy Uehara, Han was very comfortable, and he was thinking about whether to prepare a ninjutsu scroll and put a set of messy things in Uehara.

Carrying it behind his back, Han almost didn't turn over, but he figured out what was going on, Han was a little crying and laughing, this chair could even be turned into a very comfortable recliner.

Deliberately finding the most remote road, there is not even a town along the way, and Han wants to hone Uehara in the course of his journey. I've never seen anyone do this, and the logistics supplies are more than the ninja equipment. I wanted to teach Uehara some survival instincts, but Han suddenly remembered one thing, one day Wutong was catching frogs, Wutong's words made Han remember deeply, he said that the frogs in the land country are not delicious, not as delicious as the country of rain......

"Teacher Han, do you want to eat chili peppers?"

Thinking about things, hearing Uehara's words, Han put down a book he took out from the backrest, "Don't be spicy." ”

"A Thousand Ninja Jokes", "Brain Teasers", "One Hundred Thousand Whys", "Grimm's Fairy Tales" and other books, Han's favorite is brain teasers, he looks at them and laughs, he laughs at them, he laughs at them, because he can't guess any of those strange questions......

"Uehara Kid!" The owl soon returned, "Here comes the fish!" ”

Handling fish is troublesome, but if it's for owls, you can be sloppy, and the scales don't need to be so clean.

"Do you want something spicy?" Uehara picked up the chili pepper bottle and hesitated, only sprinkling a little.

"Yes!" The owl flapped its wings happily.

"And also!" Seeing that Uehara sprinkled a little bit and stopped, the owl was reluctant and continued to let Uehara put peppers.

"And also!"

"And also!"

……

"Your uncle!" Half of the bottle of chili powder was emptied, Uehara was speechless, his eyes rolled, "Don't give it!" ”

The sea fish should be fishy by adding ginger slices to be delicious, and the fish meat is slightly bitter, it is better to put some white sugar, and the dried fish is not delicious enough to make soup, so the food of Uehara and Han, Uehara makes fried sea fish with rice. Onigiri Uehara can't make it, and it won't be a bento, and it won't be sushi.

"Sea fish is expensive, isn't it?" Han asked as he ate.

"Super expensive!" Uehara didn't lift his head.

"Then why ......"

"I've found out," Uehara felt a chill, "all the garbage and dirty water of the land country is discharged into the Shinano River, and the freshwater fish must be dirty, and I won't eat the fish here anymore!" Disgusted to look at the owl's grilled fish, Uehara gnawed on his fish head with taste, eating fish head is Uehara's favorite thing to do.

"Stop and hurry in the afternoon." Uehara's fish didn't know how to do it, and there were no spines at all, Han glanced at Uehara and came up with an inexplicable sentence.

"Why?" Uehara was a little puzzled.

……

As a companion who has fought side by side with Han, Han is very familiar with owls, but the relationship between the two of them is not very good, from the fact that the owl and Uehara are noisy, and the owl hardly cares about Han, which can be seen from here.

The owl goes up and down in the air, all kinds of drifts, S-shaped, Z-shaped, and it can fly upside down!

"The owl has that kind of device that was removed from the ninja umbrella on both wings to launch a thousand copies," Uehara and Han carefully explained, "We can make the small cylinder ourselves, and the owl is a lighter ......."

On each of the owl's two "wings", there are two small cylinders hidden under the feathers, and there are additional senbens inside, so that the flight distance will be longer and more stable. The special thousands, coupled with the acceleration of the swoop, after the owl flew slightly at low altitude once, there were four more thousands of parallel lines on the ground, and the thousand books had not yet come and had to be smeared with poison, otherwise it would be even more deadly.

"The owl's weight-bearing capacity is still lacking," Uehara pointed into the distance, "It can only launch about four attacks like this, about two hundred thousand copies." ”

As soon as the words fell, something more exciting happened, in addition to the Senbon launcher like a fighter wing gun, Uehara also installed a "bomb throwing device" on the owl's abdomen.

"Half of those detonators are made of lead pellets, and the other half is attached to hooks, and when the owl opens the box, the detonators will be cut through the hooks and fall quickly."

"But there are still problems," Uehara scratched his head in annoyance, "how to make the detonation charm explode before it lands accurately, it depends on the training of the owl." "The owl doesn't know how to train, Uehara lets it out, it travels all day long, not to mention how pleasant it is.

"And the owl's claws," Uehara handed the claws in his hand to Han, who was very interested, "With this thing, the owl has no problem even holding the enemy's ninja knife, and, hehe, if it grabs the enemy's vital ......"

"I have no objection to Uehara going to the Ministry of Intelligence," Han looked at the owl that destroyed the target in the distance in minutes, and looked inexplicable, "The work of the Ministry of Intelligence is almost the safest in peacetime, but in wartime, it ...... Uehara, you can consider going to the Ninja R&D Department. ”

"Ninja R&D Department?" Uehara's eyes lit up, "This is good, this suits me, but ......" Uehara looked up at Han's eyes, "There is no safe place in the ninja world, and it is impossible to hide from danger forever." I must go to the intelligence department, and confront the enemy's intelligence infiltration team, as far as I know, Konoha White Fang likes to go deep behind enemy lines the most......" Uehara unconsciously clenched his teeth.
