Time passed, and Aoyagi is now a fifth-year student at the ninja school.

In the barbecue restaurant, after a busy day, everyone gathered at the table.

"Manager," Nishida and Amamiya stood up together before the meal, bowed, and said, "Amamiya and I will leave here next month." We're going to open a small shop. ”

The hand reaching for the chopsticks paused, retracted, and the store manager nodded: "I see." What kind of store are you going to open? ”

"We were planning to open a shop selling wood carvings and some trinkets, and with our own savings and the help of our relatives, we had already bought one. Preparations are underway now, and it should be ready to open in two months. Nishida replied.

"That's congratulations. If you have any difficulties, you can tell me and I'll see if I can help. On the day of the opening, we went to the show. ”

"There was nothing difficult about it. Thank you very much to the store manager! ”

After the two sat down, Masaoka Makoto spoke first: "Nishida-san and Amamiya-san, congratulations, you have your own shop." ”

Everyone congratulated the two of them.

The people in the store have worked together with the two for a long time, watching them become lovers step by step. Now they are finally going to have their own careers, and everyone is happy for them. After coming to the small shop and getting on the right track, they should be about to get married.

"Alright, let's go."

Although I am happy that they can have their own careers, I am inevitably a little reluctant to work together for so long and suddenly learn that they are about to leave. The atmosphere at the dinner table tonight was a little deserted, and everyone ate silently.

After Nishida and Amamiya formalized their relationship, Nishida had to send Amamiya home first every night. Since then, every time Aoyagi goes home, he is alone, and it's been three years.

Walking on a deserted, dimly lit street, surrounded by only the sound of your own footsteps. Aoyagi felt a little emotional. I didn't expect Nishida and Amamiya to leave. The scene of going to the summer festival with them seems to have only happened yesterday, and the time of parting is already coming.

I'm a witness myself. It seems that they took themselves as an opportunity to slowly start together.

It's good that they can live such an ordinary but happy life. However, the storm is coming, and there is no strength, so you can only go with the flow and passively accept your fate. You must continue to work hard to cultivate, and if you succeed in surviving the turmoil that has swept the ninja world, then you can live the life you want to live.

………………

At night, in the bedroom alone, the lights are on.

Unfolding the scroll containing the two secret arts, Aoyagi read it carefully again, thinking.

In the past few years, I have been using these two secret techniques to strengthen stem cells in various parts of my body, but carefully speaking, the main strengthening is the muscles, bone marrow, internal organs, and brain, and I have not strengthened various sensory organs.

I wonder if I can strengthen various sensory cells with secret techniques? In this way, his disadvantages in reconnaissance may be able to make up for it, anyway, he only needs to spend more time every day to refine his cells, and it doesn't delay much.

After carefully examining the scroll, Aoyagi found that the secret art did not explicitly state which body parts could not be strengthened, so it was worth a try.

Just what kind of chakra are you going to use? Is it physical or mental?

Sensory organs, which are not only physically oriented, but also closely related to the nervous system, exchange information with the brain very frequently. So is it necessary to strengthen the spirit and strengthen the physical chakra and baptize these cells at the same time?

Conjectures need to be confirmed by practice.

Aoyagi sat cross-legged on the bed, forming a war seal, carefully baptizing the tactile cells on the skin of his left arm with chakra.

Anyway, there are a lot of tactile cells in the body, and even if something goes wrong, it is only a small area that temporarily loses the sense of touch, and there is no obvious harm to yourself.

Aoyagi then baptized the cells with a chakra that strengthened the spirit and a chakra that mixed the two, and recorded in the experiment book three specific areas that were treated differently, as well as the sensations of the body.

Okay, let's repeat today's test every day, and see what difference these baptized areas will be in half a month.

………………

"The detonation charm is a consumable forbearance with good lethality and concealment. It's small and portable, and it's powerful, and most ninjas will be severely injured and ineffective if they are unsuspected. The disadvantage is that the price is relatively high. ”

"Proper use of the Detonator Charm will help you defeat enemies who are stronger than you. For some ninjas who are not lethal enough, the detonation charm can make up for their shortcomings in attack ability, and it is a must-have ninja tool......"

After a brief introduction to the detonation charm, Sugimoto explained the explosion principle of the detonation charm: "There are three kinds of charms drawn on the detonation charm, one that transforms the chakra into an explosion, one that converts the chakra into heat, and one that is a seal. When used, only a certain amount of chakra needs to be injected, and the charm will convert a small amount of chakra into heat, most into explosive energy, and some to seal the energy. ”

"When the temperature rises to a certain level, the detonation charm will start to burn, and the burning will destroy the seal on the detonation charm, and when the seal is completely destroyed, the explosive energy will be released, producing an explosion. If the Detonation Charm is extinguished before the seal is completely broken, it will not detonate. ”

"There is also a kind of detonation charm, which itself has sealed the chakra, and will start to burn when triggered by certain conditions in the outside world, and then explode. This type of detonator is usually used to set up traps, or to save chakra. It's just that the chakra inside will gradually decrease over time, and it will have a corresponding expiration date. The longer it is left out, the weaker it becomes, and even when the chakra finally dissipates cleanly, it becomes a piece of waste paper. Due to the different structure of the spell, it is not possible to activate this chakra detonation charm by re-entering the chakra. ”

"Broadly speaking, the detonation charm can be divided into the above two types, those that do not contain chakras and those that seal chakras in advance. Generally, the detonation charm of the chakra sealed in advance is more difficult to make, and the price will be higher. There is also a limited expiration date, so ninjas generally use detonation charms that do not contain chakra. ”

"You need to be aware of the time between the time the chakra is injected and the time when the detonator is detonated, and you must make sure that the detonator is in front of the enemy when it explodes. Don't miscalculate, blow up into the air, or even injure yourself by mistake. Sugimoto's face was serious, and he raised his voice to remind the students in the audience.

"While there may be some differences in the detonation time of different detonation charms, in general the difference is no more than one second. So, you just have to take a detonation charm and try it to know the approximate detonation time. ”

Sugimoto pulled out a detonation charm and clamped it between his index and middle fingers: "I'll show you below, pay attention!" As soon as I say that, I will start injecting chakra. With that, Sugimoto immediately injected chakra, and after about a second, the detonation charm burst into flames.
