The battle is over, and the battlefield is cleaned up.

The oil girl Tetsumaru was satisfied with the performance of the three students in the battle, and the three shinobi annihilated the squad led by the upper shinobi and suppressed the upper shinobi in two minutes.

This battle proved the strength of the three people, and they had steadily reached the level of the middle ninja, and they were only a few missions away from accumulating before they could be promoted.

However, the oil girl Tetsumaru planned to let the three of them wait for a while before considering promotion, mainly because he felt that there would be a big battle soon, and at this time, letting the three little guys be promoted was probably to participate in the big battle as captains, which was too dangerous.

In addition, the current strength of the three lower ninjas has reached the limit of physical development, and every day can grow one day, at this time, it is most taboo to learn some skills that damage the potential, and as a teacher, the oil girl Iron Pill thinks that he can't just let go.

The work of cleaning up the battlefield is mainly in charge of Hiroshi Uchiha, who asked the oil girl Tetsumaru to install ten hands for him.

In Team 121, Uchiha Hiroshi and Inuzuka Ao are responsible for facing the enemy head-on, and the two of them face great risks in battle, and they have also encountered fatal dangers in the mission, and Uchiha Hiroshi even opened his eyes because of this.

These two subordinates endured the constraints of chakra, and the secret ninjutsu could only be used as a killer weapon, mainly relying on physical skills to fight, and there was an urgent need to enhance the combat effectiveness of close combat.

The inspiring Oil Girl Iron Pill selects several suitable insects from the appendage worms, that is, the component insects used to increase the power or melee attack power of the giant insects, as weapons and equipment for the disciples, and then adjusts them according to the actual combat feedback.

Appendicles have been proven to be particularly useful in close combat, as they are completely inintelligent, controlled by ninjas, and their use depends on the ability of the wearer.

For example, Inuzuka Tail is a Hanhan, and the combat mode is straightforward, so you can only use the fixed appendage insect attached to the arm, and there are only two states: retracted and unfolded, and it is simply used as a weapon and armor.

Ninjas with excellent talents, such as Uchiha Hiroshi, can be more flexible after mastering the psychic silk, especially after Uchiha Hiroshi awakens the Sharingan, he obtains dynamic vision, and his control is more flexible and accurate.

Oil Girl Tetsumaru specially made a special appendage for him, he referred to Spider-Man's nano armor, based on the spider to enlarge two of the legs, and finally combined with five appendages.

These are multi-purpose appendages attached to the shoulders and waist, with ten appendages that can be used not only for fighting, but also for various jobs.

But a back-row ninja like Nara Yoshino is not good at hand-to-hand combat, and the configuration of the appendicle side adds unnecessary burden, and the performance of various appendages is not satisfactory, so he can only give up in the end.

The oil girl Tetsumaru guided Nara Yoshino to focus on ninjutsu, combined with the water escape and glue technique, and developed the water escape spider silk technique and the water escape spider web technique under the guidance of the oil girl iron pill. Combined with the shadow secret technique, it is used in a variety of battles, and it takes on the responsibility of supporting and controlling the field very well.

Team 121 continued to build the mission, and the attackers had chosen a time to be completed to attack, and the remaining finishing touches on the bridge construction were quickly completed.

Signal summons the ninja in charge of the inspection, gets the mission completion certificate from him, and the four of them return to the camp.

The oil girl Iron Pill, who handed over the task and got the mission money, was intercepted by the herald ninja before she left.

The masked herald ninja handed over a scroll: "The oil girl is a special ninja, the commander assigned the 121 squad to escort the mission, this is the mission book." ”

"Again?" The oil girl Tetsumaru hates escort missions the most, and this has long been spread among Konoha ninjas, and almost everyone knows about it.

As the war continues, a new generation of outstanding ninjas has come to the fore, among which the oil girl Sanjie is highly known and very personal.

The all-round ninja oil girl Shiguro, who has mastered the inheritance of parasitic insects, and the dust poisonous insects developed are dead at the touch, and his personality is calm and silent, and he is never picky about performing tasks, and maintains a record of zero mission failures.

There is also the oil girl, who has mastered the inheritance of parasites, developed and perfected the traditional parasites of oil girls, and at the same time took into account all ninja abilities such as detection, tracking, combat, defense, and medical treatment, and is a more versatile ninja.

It's the one who, especially the one who doesn't have a sense of existence, everyone knows that they just can't remember the name.

The giant insect makes the oil girl iron pill, controls large insects and giant insects, is good at melee combat and strong attacks, is good at training subordinates, and hates high-mobility tasks.

"Okay~Let's ~" The twisted oil girl Iron Pill still accepted it.

The ninjas of the Oil Girl family have never refused orders, and of course, they don't play with their lives at critical moments, and they don't pursue 100% completion.

Including the strongest patriarch has a record of mission failure, and the 100% completion rate that Shiguro and Tetsumaru maintain at the moment is actually lucky enough, and all the tasks they take are within the scope of their strength.

The oil girl Tetsumaru took the mission book with a disgusted face, and checked the mission command password with the herald ninja, confirmed the mission details, and then stamped the receipt scroll with a private seal, and finally injected chakra to prove that the mission had been delivered.

Sending the herald ninja away, the oil girl Tetsumaru sighed.

Several bridges have been built in a row, and Hiroshi Uchiha and Inuzuka Ao have long been impatient, and their stomachs are full of resentment about to explode.

Nara Yoshino doesn't complain, but people are getting lazier and lazier.

Forget it, I don't like escort tasks, but the three students should also switch mission types.

……

A few days later, on the edge of the main road in the Land of Fire, the oil girl Tetsumaru found a large tree that satisfied him: in the prime of life, tall enough, with a well-developed root system and lush branches.

He casts a psychic spell that summons five hives and unleashes the mother nest zerg.

The fat larvae are responsible for carving burrows in the large tree species, rustling the large trees, and soon drilling four holes in the trunk of the large tree, and then burrowing deep into the trunk.

The Oil Girl Iron Pill places four key bugs in the burrow, and they immediately pupate. These four kinds of bugs have different functions, respectively assume the functions of receiving, amplifying, and transmitting signals, plus the brain worms that will develop into a mother nest, together form a mother nest that contains signal transmission capabilities.

Well, it can also be regarded as a ground signal base station, through which information can be transmitted, but there is no dial-up function, and each communication is equivalent to a group of clear code notifications.

The technology related to dialing may or may not be complicated, but the oil girl iron pill will not be able to do it. This is the so-called meeting is not difficult, the difficult will not, interlaced like a mountain, the oil girl iron pill can get a very simple radio signal It takes a lot of effort, as for dialing, forget it.

Isn't it just that every time a message is transmitted, the ninja world is energized, it doesn't matter, anyway, only the entire ninja world can receive the signal.

Isn't it that he has to consume a huge amount of energy every time, and it doesn't matter, no matter how big the consumption is, he doesn't need to spend money on iron pills.

After the communication worm pupae is completed, it will expand up and down along the burrows dug by the longhorn larvae, extending its tentacles to every branch and every root system.

The large surface area is conducive to receiving and transmitting signals, and the large root system is conducive to shielding the insects from expanding a larger space at a deeper level, which will be the main body and warehouse of the mother nest, which is used to store sugar, fat, water, minerals, and ensure the survival of communication insects and parasitic trees.

The mother hive also has three types of affiliated colonies: sugar ant colonies, leaf-cutting colonies, which supply fat, and tiger bee colonies, which defend large trees.

The affiliated insect swarms will build their own nests around the big tree, and operate a complete and stable brood, integrating the three functions of supply, reproduction, and communication, and from then on, the oil girl Tetsumaru will control the information hegemony of the ninja world.

The second purpose of building the mother nest is to graze the knife mantis, known as the giant insect envoy of the oil girl iron pill, and there are only eighteen giant insects in her hand.

But there was no way, the village specially issued a prohibition order for him, and the oil girl family could not raise more than ten giant insects in the village, plus the eight banned in the psychic array, that's all.

Obviously, my ideal is a million army, what the hell is the eighteen Arhats, it's outrageous

Of course, he can also understand the Hokage's concerns, the sword mantis is a big guy with a body length of several meters and a weight of 400 kilograms to 3 tons, which is full of destructive power, and its image is hideous and vicious, it is really not suitable to raise it in the village, and it is not good to scare children.

Bah.

The number of psychic slots in the family is also limited, and there are only twelve large psychic slots that can be used by the sword mantis, which is not enough to replenish at one time, and it is impossible to monopolize them all.

It can only be stocked into the wild, but how to manage, how to dispatch and command has become a big problem, if you throw it out for stocking regardless of it, and finally the genetic mutation spreads, forming a world-destroying insect plague It will be funny.

Of course, the oil girl iron pill is not afraid of the knife mantis mutation, this kind of giant insect that leaves its own feeding and will hang up at any time can only become a cherished animal, and it is impossible for an insect plague to occur.

What the oil girl Tetsumaru is afraid of is the dozens of tool worms parasitic in the body of the knife mantis, once this parasite is free, the direction of their mutation is unpredictable.

Just when the oil girl Iron Pill was thinking about whether to eliminate the sword mantis, a turning point appeared, and the sword mantis adapted to the ninja environment by itself, produced chakra on its own, and became a ninja insect that gave birth to chakra on its own.

Thanks to the giant worm's own mastery of chakra, the sword mantis not only has the manufacturing cost plummeted, but also can take the initiative to respond to the secret art and field enchantment, and the effective distance of communication has reached an exaggerated fifteen kilometers, and the command efficiency has been greatly improved.

With this exaggerated control distance as a basis, it was feasible to conduct remote command by amplifying the signal, so the construction of additional broods was put on the agenda.

The new brood is not only capable of breeding a large number of mantises, but also has the ability to signal base stations, and the new generation of brood can receive the signal of the oil girl's secret art, and after amplification, it can be transmitted again.

The amplified signal can be effectively transmitted to large insects within a few hundred meters, parasites within two kilometers, knife mantis within forty kilometers, and another female nest within two hundred kilometers.

With the four broods as relays, plus two base stations near Tetsumaru's house and the Kawanokuni camp (no brain worms, only signal base station related functions), it connects Konoha Village to the Kawanokuni camp, and can directly mobilize the sword mantis at home to rush to the front line of Kawanokuni.

Of course, the defect of the knife mantis in terms of endurance is that it is not capable of traveling 900 kilometers at a time, and they will die of exhaustion after running 300 kilometers in a row, and irreversible organ failure caused by hyperthermia.

The function of the brood is to allow the mantis to rest after traveling 200 kilometers, while the mantis in the original brood continues to move forward, so as to achieve the ultra-long-distance mobilization of the mantis in this relay way.

Another function of the brood is that its own reserve of bugs can be used for nearby support, and through the establishment of a series of broods, the entire escort route has become its own position, and there is no need to worry about the replenishment of the knife mantis on this route, which makes the oil girl Tetsumaru very satisfied.

After repeated checks, the oil girl iron pill confirmed that there was no problem, and all the hardware construction was ready, and the last step was ready to activate the signal connection.

The oil girl Iron Pill divided into three shadow clones, surrounded the trunk of the big tree and began to cast a spell, each of the four figures stared at the handprint order table in front of them, sealed with all their might, and turned their hands into a phantom.

The signal activation is improved according to the secret technique of the oil girl, the core remains the same, and countless amplification and range extension functions have been added, and the layered spell structure requires an exaggerated and complex spell process.

The spell construction process could not exceed five minutes, and after repeated streamlining, it still required more than four thousand handprints, and the hand speed of the oil girl iron pill with four seals in one second was too late, so she had to separate the shadow clones and perform the spell together.

The long spell was completed, and as the final handprints were finished, the chakra poured down like a tidal wave on the three base station insects in the heart of the big tree.

The insect's body shook violently, and its tentacles quickly extended along the dug tree hole, causing the canopy to tremble together, and at the same time, waves of strong signals were sent out, and they quickly responded, completing communication with the other five signal sources.

The oil girl Tetsumaru inspected the operation of several other mother nests, as well as the situation of the stocked giant insects, and testedly transmitted orders to all the military stations, simulating operations such as mobilizing knife mantises, hatching insect eggs, and pupating knife mantises, and even simulated a self-destruct operation.

After the oil girl iron pill was checked, everything was normal, and then she waited for ten days for the development of the mother nest to be completed, and then began to breed larvae, and the continuous pupa turned into more than 30 kinds of insects, and finally assembled into a new knife mantis.

He breathed a sigh of relief, started camouflaging the four tree holes, and left.

After an hour of sprinting, the oil girl Tetsumaru caught up with the baggage team and secretly exchanged with his shadow clone, and no one noticed that the leader of the ninja squad in charge of the escort had ever left the team.

This was done to keep it a secret, and the oil girl Tetsumaru didn't want Konoha to know about the existence of the brood, and he didn't think that the super-controlling Hokage-sama would let himself master more giant insects.

When the total number of broods reaches 200, the marine version of the brood is developed, and the technical problems of the bugs inserting themselves into the base are solved, the oil girl iron pill can finally gain freedom.

Because at that time, the speed at which he inserted the brood would exceed the speed at which Konoha cleaned it up with all his might, and with this strength as a backing, it doesn't matter what Konoha Hokage's is, uncle, you can do whatever you want, and you won't do anything if you don't want to.

In order to meet the travel distance, resource yield and other conditions, this brood can only be built not far from the traffic artery, so it has to be more careful.

In the final analysis, it is because the sword mantis is not strong enough, not only is the physical fitness not strong, but there are not enough chakras, otherwise it is more convenient to directly set the blood contract and channel at will.

There is no need to consider the range of maneuver of the knife mantis, the separation distance of the brood can reach more than 300 kilometers, it is really not possible to build some base stations that relay signals, and the production brood can be built in the no-man's land at will.

This makes Tie Pill even more looking forward to the super giant insect with a body length of dozens of meters and a weight of more than dozens of tons, this body type, even if it does not have a long brain, it can have enough chakra, which is enough to apply to the blood pact psychic.

When the three-ninja psychic giant beast pretends to be, he can also take it out and show it, and everyone's expressions must be very interesting at that time.

It's a pity that the super giant insect is just a dream for the time being, and the red and black giant beetle that was once the closest is also dead, and the fifteen-meter insect lacks self-sustaining power, and is born with various congenital diseases, and it can't even hold on for four months.

Now that the key reference prototypes of the super giant scorpion and giant ant have not been obtained, the research of the giant insect of the oil girl iron pill has come to a standstill, and she can only work on the construction of the mother nest, and strive to increase the number when the monomer cannot be improved.

Moreover, history tells Tetsumaru that it is tiring and hard to build infrastructure, but this hard work will not disappoint people.

Someday, these jobs will become the cornerstone of his meteoric rise.
