Hanyu set out from Konoha with a team of ninjas and rushed to the easternmost front line of the Fire Nation overnight.

What they want to protect is a vast sea.

The garrison and surveillance range of the Eastern Front is actually similar to that of the last major war, after all, what the Fire Nation needs to be wary of is nothing more than the fog in front of the sea.

It's just that the external situation on Konoha's side is still slightly different from the last war, and now the Uzumaki clan has been integrated into Konoha internally, so it is equivalent to saying that it has lost an important external fulcrum - the country of Vortex has no way to help Konoha.

There are certainly advantages and disadvantages to such a change in foreign aid and non-discrimination that exists all the time, and it cannot be evaluated in detail if only war is considered.

However, considering that the northeast direction of the front that Hanyu has to defend is the inviolable land of iron agreed by the ninja world, compared to the border of the land of fire, the line that Hanyu's team has to defend is actually not too long.

The last time the Cloud Hidden Ninja entered the Iron Country, it caused a series of troubles, so even if the ninjas went to war again, under normal circumstances, no one would easily touch the brows of the samurai.

This is good news for Hanyu.

If there were no operational requirements and only a monitoring mission, the number of people under his command would certainly be more than enough.

In addition to the ninjas who fight regularly, Hanyu's team also has a medical team of twelve people in three squads. In general, the percentage of medical ninjas is not high, but it is certainly barely enough, and considering that medical ninjas are the most scarce resource in wartime, Hanyu has nothing to complain about in this regard.

The team set off in the evening, then slowly advanced, and by noon the next day, it had already arrived at the mission location...... When the ninjas marched in groups, the speed of the march was not comparable to the speed of a single person or a small team, not to mention that Hanyu did not give the order to go at full speed at this time.

After arriving at the eastern coast of the Fire Country, the team did not rest at the first time, but immediately launched a formation.

The team was divided into reconnaissance squads and sprinkled on the eastern front of the Fire Nation according to the pre-arranged arrangement. Although Hanyu and the others were tasked with the reconnaissance of the fog, due to their own weak combat effectiveness, Hanyu finally stipulated that the range of activities of the Konoha ninjas should not cross the north-south longitudinal line of the Vortex Country, so their farthest detection distance was only based on the Vortex Country, plus the ninjas' farthest detection methods were only the extended distance to the east.

"Let's choose here, we only have such a small number of people, although the command has the necessity of concealment, but whether it can achieve the desired concealment effect, it can only depend on the extent to which the anti-reconnaissance means of foggy concealment can be achieved."

Hanyu chose a dense forest about five kilometers from the sea as the location of his headquarters—even if his team was relatively small, at least 150 ninjas would be a squad and a half.

After all, ninja warfare is to emphasize small and precise, and of course a streamlined command system is required for so many people to be assembled together.

"It would be nice if the terrain could be a little higher, but this seaside is mostly full of unobstructed tidal flats and impact plains, and it would be nice to have a place like this."

Uzumaki Ziko, who stayed by Hanyu's side, said that although it was not enough to rely on the terrain and vegetation alone to isolate the enemy's detection and detection, even if it was only visual obscuration, it was better to have something than nothing.

"Another point is also very important, the best reconnaissance location is also the enemy's counter-reconnaissance location at a glance, and the location of the headquarters is also the same, 'excellent location', the enemy will also find an accurate one." Hanyu added.

Uzumaki Zikou nodded, "If the location is chosen here, I will arrange the camouflage enchantment of defensive enchantment and anti-detection, and after these peripheral enchantments are arranged, the central chakra detection technique will be opened, and finally the infrastructure of the command will be arranged." ”

A large-scale, centralized chakra perception technique, a technique that Konoha hadn't yet mastered during the last ninja war. To be precise, it was a new technology developed after the Uzumaki clan came to Konoha and worked with the rest of the village's development department.

There is no doubt about the progress of technology, and when this exploration barrier is opened, the west of the land of Yu, almost slightly beyond the middle line of the sea area between the land of fire and the country of water, will enter the perception of this technique.

In the area it encompasses, slightly more intense chakra activity will be perceived, compared with the traditional whirlpool perception, white eye insight and other point-like, linear detection, such a detection technique brings regional reconnaissance capabilities undoubtedly have a more systematic function.

It's just that although this large "searchlight radar" is technologically advanced, it can't actually be called epoch-making significance, and to some extent it's even a manifestation of the deterioration of ninja ability - after all, during the last ninja war, Konoha didn't need this kind of thing at all.

Because...... During the last war, no matter what happened in the ninja world, it was difficult to hide the perception of the second Hokage. His perception ability alone is simply greater than this kind of reconnaissance technique, and he doesn't know where the scope is.

And it's more accurate, more efficient, and the feedback is more timely.

In a sense, it is actually a good choice to dig the second Hokage out of the grave and use it as a radar.

Although the second Hokage didn't even have a grave, Hanyu felt that he must have fully met the conditions for reincarnation in the filthy earth.

It's a pity that manipulating life and death is a way to go against human ethics, and the third generation Hokage respects his teacher very much, and he will definitely not let everyone toss the deceased - further, since he can use the second generation as a radar, he can use the first generation as a thug, which is not a bad game.

The wife of the first generation is still alive, and the grandson of the younger generation is going to be against the sky?

It's a pity...... Ahem, it's wrong, it shouldn't be a pity, anyway, the current detection technique is enough.

Open the detection technique as a large radar, and then fill the detection area of the radar with the ninja squad as an active eye position, the powerful detection ability of the detection technique provides the first protection for the detection ninjas, and the detection ninjas provide more detailed information for the detection enchantment, and the combination of the two is a complex and systematic wartime intelligence system.

Communication between ninja squads and between squads and headquarters was another issue, psychic beasts or domesticated birds could theoretically meet everyday needs, and in the most urgent situations, Hanyu was ready to summon slugs for the scout team.

Although different slugs cannot play the role of instant walkie-talkie in "mind transmission", as long as a slug is disabled, the information it has will return to the consciousness of the body, which is equivalent to the information being recovered.

In fact, the slug's ability to infinitely split and re-merge is actually quite a buggy thing.

As for the overall personnel arrangement, considering that this surveillance mission is a long-term mission, and if the fog does not launch a large-scale attack, it will even continue until the end of the war, so for the "endurance" of the entire mission, Hanyu divided all 150 people into three groups, so that the team can maintain two groups of personnel to carry out the mission, one group of personnel to rest, and then alternate rotations.

If the mission time were averaged over each day, it would mean that the ninjas would have to live a normal life of sixteen hours a day and eight hours of rest for years on end......

In this comparison, ninjas are nothing more than the same - if a weak modern person tries a little harder, he can even compare the intensity of his work with the ninjas.
