Hanyu took a team of ninjas from Konoha and rushed to the easternmost front line of the Kingdom of Fire overnight.

What they want to protect is a vast ocean.

The defense and surveillance range of the Eastern Front are actually similar to those in the last war. After all, what the Kingdom of Fire needs to be vigilant is nothing more than the fog hidden in front of the sea.

However, the external situation on Konoha is slightly different from the last battle. Now the Uzumaki clan has integrated into Konoha, so it means that it has lost an important external fulcrum - the Uzumaki Country has no way to provide assistance to Konoha.

The integration of foreign aid and inseparable from each other is definitely beneficial and disadvantageous for such changes. If only war is considered, it cannot be evaluated in detail.

However, considering that the northeast direction of the front that Hanyu wants to protect is the invasive Iron Country agreed upon by the Ninja Realm, compared with the border line of the Fire Kingdom, Hanyu's team actually has not been too long.

The last time Yunyin Ninja entered the Iron Country, it caused a series of trouble, so even if the ninjas started another war, under normal circumstances, no one would easily touch the samurai's brows.

This is good news for Hanyu.

If there is no combat requirement and just a surveillance mission, his number of people will definitely be more than enough.

In addition to the ninjas who fight conventionally, Hanyu's team also has a medical team composed of three squads of twelve people. In general, the proportion of medical ninjas is not high, but it is definitely barely enough. Considering that medical ninjas during wartime is the most scarce resource, Hanyu has nothing to complain about in this regard.

The team set off in the evening and then slowly advanced. By noon the next day, they had already arrived at the mission location... When the ninjas were walking in teams, their speed of advance was not as good as the speed of singles or teams, not to mention that Hanyu did not give the order to advance at full speed at this time.

After arriving at the eastern coast of the Kingdom of Fire, the team did not rest as soon as possible, but immediately unfolded the formation.

The team was divided into one reconnaissance team after another, and then it was sprinkled on the eastern front of the Fire Kingdom according to the pre-arranged arrangement. Although Hanyu and others were tasked with reconnaissance of Mizuno, because of their weak combat power, Hanyu finally stipulated that the range of Konoha Ninjas' activity must not cross the north-south vertical line of the Eutropium Country, so their maximum reconnaissance distance was only based on the Eutropium Country, and the ninjas' most farthest reconnaissance method was extended eastward.

"Just choose here. We only have this small number of people. Although the command center has the need to hide it, whether it can achieve the expected hidden effect. It can only see how much Wu Yin's anti-reconnaissance method can achieve."

Hanyu chose a dense forest about five kilometers away from the sea as the location of his command center. Even if his team is relatively limited, at least 150 ninjas have to be considered a half-group.

After all, Ninja's battles need to emphasize small and sophisticated. Of course, so many people gather together requires a streamlined command system.

"It would be great if the terrain could be slightly higher, but the seaside is mostly full of tidal flats and impact plains, so it would be nice to have such a place."

Uzumaki, who stayed beside Hanyu, said this. Although we cannot expect to isolate the enemy's reconnaissance and exploration by relying solely on the terrain and vegetation, even if it is just visual obscurity, it is better if there is one than if there is nothing to come.

"There is another important point. The best reconnaissance location is also the enemy's clear anti-reconnaissance location. The same is true for the command center's location. In an excellent location, the enemy will also find a correct one." Hanyu added.

Uzumaki Zike nodded, "If you choose this position here, I will arrange the defensive barriers and the camouflage barriers for detection. After these peripheral barriers are arranged, the central-type chakra detection technique will be opened, and finally the infrastructure arrangement of the command center."

Large-scale, centralized chakra perception technique, this is a technology that Konoha had not yet mastered during the last ninja war. To be precise, it was a new technology developed by the Uzumaki clan after he came to Konoha and cooperated with other development departments in the village.

There is no doubt that technological progress is made. After this exploration barrier is opened, the west of Tang Kingdom will almost slightly cross the sea center line between the Kingdom of Fire and the Kingdom of Water, and will enter the perception of this technique.

In the area it covers, slightly more intense chakra activities will be perceived. Compared with the traditional vortex clan's perception, eye-blank insight, etc. point-like and linear reconnaissance, the regional reconnaissance ability brought by such reconnaissance techniques undoubtedly has more systematic functions.

However, although this large-scale "search radar" has advanced technology, it is actually not of epoch-making significance. To some extent, it is a manifestation of the deterioration of ninja abilities - after all, during the last ninja war, Konoha did not need such things at all.

Because... during the last battle, no matter what kind of turbulence in the ninja world was, it was difficult to hide the perception of the second generation of Naruto. His perceptual ability was so wider than this kind of reconnaissance technique.

And it is more accurate, more efficient, and more timely feedback.

In a sense, digging out the second generation of Naruto from the grave as a radar is actually a good choice.

Although the second generation Naruto didn't even have a tomb, Hanyu felt that he must have fully met the conditions for reincarnation in the filthy land.

It’s a pity that manipulating life and death is a practice that goes against human ethics. The third generation of Naruto respects his teacher quite well. He will definitely not let everyone mess with the deceased. Let’s go further, since the second generation can be used as a radar, then the first generation can be used as a thug. This is no longer a joke.

The first generation's wife is still alive, and the younger generation's grandson is about to rebel?

What a pity... I'm sorry, I was wrong, it should be nothing bad. Anyway, the current exploration technique is enough.

The open-minded exploration technique is used as a large radar, and then the ninja team is filled in the radar's exploration area as the active eye position. The powerful detection ability of the exploration technique provides the first level of protection for the detection ninjas, while the detection ninjas provide more detailed information for the exploration barrier. Combining the two, a complex and systematic wartime intelligence system is established.

Communication between the ninja team and the squad and the command center is another problem. Psychedelic beasts or domesticated birds can theoretically meet the daily needs. When the most urgent situation is really, Hanyu is ready to summon slugs for the reconnaissance team.

Although individuals of different slugs cannot "transmit their minds" to play the role of a live walkie-talkie, as long as a slug is relieved from psychic communication, the information it has mastered will return to its original consciousness, which means that the information has been recovered.

In fact, the ability of slugs to split infinitely and re-fusion is actually a very buggy thing.

As for overall personnel arrangement, considering that this surveillance task is a long-term task, if Mitsuki did not launch a large-scale offensive behavior, it would even last until the end of the war. Therefore, for the "endurance" of the entire mission, Hanyu divided all 150 people into three groups, so that the team could maintain the state of two groups of personnel performing tasks, one group of personnel resting, and then alternate rotations.

If the task time is averaged to every day, it means that these ninjas may have to live a normal life of working sixteen hours a day and resting for eight hours a day for several years...
