After the white fog, three men and one woman still appeared in the same place, the bear turned into a stout middle-aged man, the fox was an ordinary middle-aged woman, the eagle played the role of a sixteen or seventeen-year-old boy, and Aoyagi himself was a boy of the same age as herself.

The four people just play the role of a family of four, ordinary and unnoticeable. According to the information, they were passing through the town.

The bear had a sword strapped to his waist, and his status as a samurai also made it possible for the family to travel alone.

The four of them looked like dusty people, and in the afternoon, mixed in the crowd and entered the town.

Groping for the hilt, Xiong said, "Let's go straight to the hotel." ”

The other three naturally had no objection and followed Xiong to the hotel. Because they were dressed as a family, the bear was in the same room with the fox, and Aoyagi was in the same room with the eagle.

The inn also provided food and drink, and Aoyagi felt that the bear already knew about it, so it would reduce the time spent outside and help it hide.

The four people who sat at the table with the transformation technique were completely a family in terms of appearance and behavior, and there was nothing special except that they were relatively silent.

Before parting, Xiong made a request: "It's safer here, you can rest assured." However, do not take off your dark uniform when you sleep, and make sure that you can move at any time. I left at half past four in the morning. ”

After returning to the room, Aoyagi took a happy bath.

In the past few days, I have been sleeping in the open air, I haven't eaten much hot food, and I don't have the conditions to take a shower, and I have to be nervous all the time, so it's great to be able to rest.

After taking a bath, he was tired and swelled up, and Aoyagi felt that his eyelids couldn't help but go down, so he said hello to the eagle, and after lifting the transformation, he went straight to bed and fell asleep with his mask.

After tidying up his things, the eagle also seized the time to rest. Tomorrow you have to sneak into a foreign country and make sure that you are in good shape.

In the mental space, Aoyagi sat cross-legged, thinking about his ninjutsu system.

………………

Not counting other auxiliary ninjutsu, only attacking and defensive ninjutsu. The main defensive ninjutsu is the water array wall and the earth flow wall, which is enough for now, and there is no need to find ninjutsu to learn for the time being.

As for the attack class, because of the practice of water nature change, the attack power of water escape ninjutsu is now stronger than that of earth escape, as long as you continue to strengthen the practice of water nature change, the power of water escape ninjutsu will naturally increase.

It's just that most of the water escape ninjutsu is based on impact power, causing damage in the form of blunt hits. At present, my cultivation of the change of water nature has not been able to give me extremely high pressure on water, and I also lack ninjutsu in the form of water cutting knives such as hard vortex water blades, so it is still difficult to achieve extremely strong cutting effects.

The practice of changing the nature of water is a water mill, which can be done at a fixed time every day. Then, after deducting the time for physical exercise, the time that can be used to develop chakra chainsaw ninjutsu in the current world is very limited.

In this case, we should cherish every practice in the outside world even more, record the phenomena and results in detail, spend more time analyzing and deducing in the mental space, and find the tricks and shortcuts of the practice as soon as possible, so that the time that needs to be spent on real-world verification will be reduced accordingly.

If you are in the middle of nowhere, you won't have time to change the nature of your cultivation, so let's put it in for now.

As for the attack routine, this also has to be deduced well. Let's first combine a set of methods for offense, defense, and support. Then, you can form a corresponding routine according to the strength or even type of enemy. These things are done in the mental space.

I don't want to attack the routine first, but let's study how to implement the chainsaw, which is much more interesting than the routine. And if it is developed, it will also become a powerful attack method, and it is also the kind that can grow. As long as you continue to increase the sturdiness, sharpness, and speed, the power of the chainsaw will continue to increase.

In the case of a chainsaw, it is mainly composed of a support in the middle and a serrated chain at the edges. As long as the support is strong enough, the key is the serrated chain.

How to achieve the high-speed movement of the sawtooth chain without destroying the structure of the chain in the high-speed movement? The focus should still be on the restriction of chakra.

The chakra is used to construct the intermediate support structure and the chain structure separately, and the outer membrane compression hardening is added to each of them, so that only the chain needs to move in a circular motion.

The first step is to construct the overall chainsaw structure, and the second is to drive the chain formed by the chakra.

What should be the specific chainsaw structure......

………………

When it was still dark, Aoyagi woke up and got up to see that it was four o'clock, and the eagle was almost finished washing.

Immediately after the eagle, Aoyagi quickly solved the sanitation problem. After nibbling on dry food like an eagle for breakfast, Aoyagi checked the various ninja equipment on his body.

At half-past four, the bear and the fox quietly entered the room of the two Aoyagi. The four of them did not use the transformation technique again, but avoided the eyes of the others and left the hotel directly and quickly in the night.

Jumping on various buildings, the four of them quickly left the town.

Xiong slowed down slightly, and when Aoyagi caught up behind him, he said, "If you want to pretend, you have to do it to the extreme." Someone will take over from us as the four of them. We just need to leave quietly without being discovered. ”

Aoyagi nodded in understanding. Try to hide your whereabouts all the time, after all, it is an assassination tactical special unit, and more often it is acting in the shadows.

As they moved away from the town, the sun was slowly rising, and the clothes of the four of them had been wet with the morning dew, and they had become dry under the body temperature and the sun, but then they were soaked with sweat.

As they hurried along the way, the closer they got to the border, the slower their speed became, and they became wary of possible ninjas.

"We've got the latest patrol here. When the Shadows go out on a mission, they need to avoid the ninjas in the village as much as possible, and do not meet them unless necessary. ”

"There is no need to worry about intelligence leakage, the patrol arrangement changes from time to time, and there is basically no regularity. And what was sent to the dark department was only a short-term patrol arrangement. ”

With the intelligence of the patrol, the four of Aoyagi easily broke through the garrison of Konoha Village and entered the place where the Land of Fire and the Country of Grass interacted.

According to the tacit understanding, ninjas will not be sent to patrol here, beyond this area, there will be ninja patrols in their respective countries. However, the area is not very large, about two kilometers wide, although the specific situation may vary from country to country depending on the topography and other factors.

"Further on, there are ninjas patrolling the Grass Ninja Village, so we need not to alert them to sneak in." The bear looked at Aoyagi, "Cat, you scout." ”

It seems that the captain has obtained my information and knows that I have some reconnaissance ability.

In response, Aoyagi closed his eyes and was engrossed in perceiving the chakras around him.
