At noon, the Uehara shift rested for two hours, and by the afternoon when the sun was about to set, he finally checked all the remaining traps. When the dust settles, Uehara finally has a chance to try out the perception of Shilersa.

As far as Uehara understands, the perception ability of a ninja is basically the embodiment of the six senses of a person. For example, the visual perception class, the secret art Sand Eye cultivated by Ai Luo in the original book, the blood step-white eye of the Hyuga family, and the ability of the oil girl clan to share information with insects all belong to this type.

The second is the olfactory perception class, the most representative is the Konoha Inuzuka clan, the ability of smell shared by the Inuzuka clan and the ninja dog, and it is a very powerful auxiliary force when detecting and tracking enemies.

The third is the sense of taste, such as the modified body of the great snake, which can sense the smell of the air with a tongue similar to that of a snake, and some ninjas with special secret techniques also have similar abilities.

There are also tactile perception ninjas, the most typical of which is Nagato, who has the eye of reincarnation, creating a continuous rain curtain in the Akatsuki base, and whenever the enemy comes into contact with the raindrops containing chakra, the relevant information will be detected by the caster.

As for the auditory perception ninjas, the mist ninja, who is good at silent killing techniques among the five major countries, has the most such ninjas.

The rarest category is the sixth sense ninja, this type of ninja often has strong mental power, and can use mental power to perceive the surrounding environment in a large range, etc., such as the strong perception ability of the Konoha Mountain clan that can cover the entire battlefield.

Chakra is a very magical thing that has an immediate strengthening effect on the body. If the chakra is delivered to the arm, the strength of the arm will increase, and if it is delivered to the eye, the vision will be sharper. Theoretically speaking, if you go through enough training, anyone can become a perceptual ninja, but theory is theory after all, human body structure is different from animals after all, no matter how trained the eyes are, it is impossible to be as sharp as a hawk, and no matter how sensitive the nose is, it is impossible to reach the level of canines, so the gifted perceptual ninja and the blood family are important strategic resources for every ninja village.

"Are you ready, Sherelle, it's time to get started." After asking the fat man to find a place to hide, Uehara motioned for the sherry to begin. He was also curious about how Shiresha was different from ordinary ninjas as a ninja with a talent for perception.

"Preparations have begun. Is the sycamore hidden? Shelersha closed her eyes tightly, and a large amount of chakra slowly gathered in her hand, slowly conveying it to her forehead.

"It's ...... Psychic ninjas, amazing. "Shelesa will be the rarest psychic power perception ninja, which surprises Uehara. Looking at the staggering towards the direction where the fat man was hiding with his eyes closed, Uehara hurriedly helped her.

"Shelersa, the process of perception, specifically, what does it feel like?"

"It's like... Like a burning fire, there is a slight burning sensation when you perceive it......" Hearing Uehara's words, Shilesa slowly avoided her eyes, frowned, and looked around, "However, this effect can only be achieved if you concentrate with all your strength, and if you open your eyes, you won't feel anything." ”

"Is Sycamore in that direction?" Shelersha pointed to a large rock not far away.

"That's right, that's amazing! Sheyler yarn. Uehara gave a thumbs up approvingly.

"Fatty, come out!" Uehara greeted the empty stone, and after a moment, the fat man who had unlocked the Rock Concealment Technique slowly appeared.

"Yes, Sheller." It's a really useful ability, but I don't know how big the range is.

"Learn Lesha, by the way, how far can you perceive it?"

"Approximately, a hundred meters...... And I can't accurately perceive whether it's a human or an animal, in fact, what I felt most clearly just now was the bonfire......" Xuelesa replied after thinking about it for a while.

"A hundred meters, it's enough, the hotter things feel, the clearer they feel, is it the perception of infrared......" Uehara silently assessed the role of the ability of the sherry yarn in his heart.

"This is a very powerful ability, Shelersha, you have to work as hard as possible, and you will be the core of the tactics of the Kamihara class in the future. You sense the number of enemies first, and then I will formulate the corresponding tactics, and then the three of us will execute them together. "As analyzed by Tuya, what Uehara is best at is the use of resources.

"Also, Shelersa, when you point the way...... Well, do you know clocks? ”

"Yes."

Well, there are also sophisticated mechanisms such as clocks, and Uehara is no longer able to complain about the black technology of the ninja world.

"When you concentrate your mental strength, you can't fight, so the battle is left to me and the fat man, but you need to quickly and accurately guide us in the direction." Uehara said, drawing a rough look at a watch on the ground with kunai, with twelve scales.

"With you as the center of the circle, you can divide twelve general directions, so when you point to the location, you can point by time, which will be very fast. For example, the position of the fat man just now is in ......"

"Two o'clock, right?" It turns out that the learning ability of Shelersha is not a little stronger than that of a fat man.

"That's right, but what about the distance?"

"Distance...... Probably, more than twenty meters? Shelersha said uncertainly.

"Uh...... I estimate that it is more than thirty meters, and this is what you are going to work on next, Xuelesa, if the coordinates you provide are accurate enough, we don't even have to rush up to fight the enemy, just release the ninjutsu from afar. Although Xuelesa's ability is not yet proficient, it is good enough, and Uehara is very pleased, and Uehara's class is getting better and better.

"Next, let's wait here for the Tuya seniors to come back, and for the rest of the time, Xuelesa, we will cooperate with you in cultivating." Uehara said hello to the fat man and quietly hid.

Waiting for Uehara to take the trouble to hide it, he was easily discovered by Shiresha.

"Uehara, you're ...... Six o'clock direction. The frowning sherrel yarn laboriously pumped chakra into the brain.

"Sycamore, you're in the direction of eight o'clock...... Don't run, I can sense you......"

"I mean, are you playing hide and seek?" Tuya took the Oishi class and rushed to the Uehara class to round out, and as a result, he saw Uehara and the fat man hiding in the grass.

"Captain Tuya, you're back. Then we can go back. Uehara removed the branch from his head and climbed up.

"Don't worry, we'll go back when the big stone class rests."

Dashi, who was in the dust, greeted Uehara in a friendly manner: "Hello, everyone from the Uehara class, the Dashi class has a good harvest today." Oishi greeted Uehara with a fat rabbit in his hand.

"Great, we're going to have rabbit meat tonight." Uehara was smiling.

"Why? Isn't it good to keep it? Why kill. Shelersha looked at the red-eyed rabbit and liked it very much, and couldn't bear to kill it.

"I said Shelersa, we are ninjas, sooner or later we will see blood, no, you have to practice your hands, the rabbit will deal with it for you, slaughtering the rabbit, it's similar to dealing with fish, it's very simple, you don't need me to teach you......" Uehara was very unreasonable, and stuffed the two rabbits into Xuelesa without saying anything.

"Senior Tuya, is it convenient to ask a question?"

"You say."

"Chakra is a combination of mental power and physical strength, I know, physical strength, with the growth of the body, as well as exercise, nutritional supplements, it will naturally grow slowly, so, as the other half of Chakra, how to train mental power?" Uehara's understanding of spiritual power is less than Chakra's, after all, physical arts are all within the scope of materialism, and the completely different power of spiritual power, Uehara's understanding is tantamount to the difficulty of elementary school students reading high mathematics.

"Mental strength, in fact, also increases with age, and training can also enhance mental strength, such as strong-willed ninjas, who are more resistant to illusions." Tuya carefully followed Uehara to explain.

"However, in general, the growth of spiritual power is very difficult, and many of them are carried out by secret arts, such as our second generation of Iwakuin, the Shadow Lady, has strong spiritual power. However, there are also some superficial ways to enhance our mental power in the shadows. Tuya thought about the secrecy rules of the dark department, but there was no such regulation, so he taught Uehara with confidence.

"Mental power is an ability produced by the brain, the dark ninja uses chakra to stimulate the brain for a long time, and the enhancement of mental power is significantly improved, the information I have been exposed to in the dark part, the most effective area is, the front end of the brain, that is, the forehead, a small area ......"

"Is it the pineal gland?" Uehara muttered to himself. In the theory of past-life biology, located between the prethalamus and thalamus of the diencephalic brain, there is a reddish-brown bean-like body, and the surface leaflets of the pineal gland are mainly composed of pineal cells, glial cells, and nerve fibers. In many online novels, there are many people with special functions, and their pineal gland development degree is far beyond ordinary people.

"I don't know about the pineal gland or anything like that, but since you mentioned mental power...... Tuya touched the scar on his forehead.

"Compared with physical injury, mental damage is more terrifying, if something goes wrong with some parts of the body, it will not affect the refining of Chakra, and if the mental power is damaged, not only Chakra refining is difficult, but also, advanced ninjutsu requires an extremely excellent Chakra control level, and the Chakra control level is closely related to the level of mental power. Therefore, it is important to protect the head in battle, especially the brain that generates mental power. Tuya looked at Uehara, who tied his forehead guard around his neck, "The existence of the forehead guard, on the one hand, is a sign of the identity of the ninja in each ninja village, and on the other hand, it can provide necessary protection for the brain and forehead. As far as I know, the materials used to make the forehead guard are one level higher than the materials used to make kunai. ”

"Uehara, it's strange why you tied your forehead guard around your neck." Tuya asked puzzled.

"Well, I didn't expect that forehead protection would have such an important use, I originally wanted to use it to protect my neck, but the neck is one of the key points." Behind closed doors, it really didn't work, Uehara listened to the advice and put the forehead guard on his forehead from the beginning.

"As I said, the brain is even more important than the body, and protection is the priority when you fight." Tuya groped for the hideous scar on his forehead, "For example, if I had lost a hand at the time, I would still be a shinobi now." ”

Tuya said to himself, his eyes were gloomy, remembering something, "But if the brain is damaged, I can only barely be a special forbearance, that guy, it's really strong......"
