In the middle of the woods, Obito and Rin sat on a cloth laid out on the lawn, and various parts and gears were placed around them. Pen & Fun & Pavilion www.biquge.info two people work hard to assemble the parts piece by piece, sometimes they can succeed, but more often they still fail.

When he fails, he stops what he is doing, touches his face with oil, and then picks up a blank sheet of paper and fills in the new test and design data on the white paper. By now, Obito has filled more than 100 sheets of blank paper, which are densely covered with various kinetic theories and digital measurement data.

"Suppose point A is 3.22bca, and point B is a three-way propulsion system CTA from the top to the end, so that the "arrow" body itself should be designed with multiple sub-guidance, and the conductor should still use the chakra system as the guiding ......."

Obito took Rin to develop his own secret weapon, as for why he took Rin with him? This is because the development of weapons is inseparable from the assistance of people who know how to control the chakra finely, and on the other hand, Obito also wants to take this opportunity to stay with Lindor for a while.

"Woohoo, it's really hard to bring soil." Lynn held the pliers in one hand, and wiped her little face, which had become oily, black and white, with the other.

The girl had her back to the sun, and her forehead was covered with sweat because of the exertion. But the girl's face is full of stubborn expressions, her eyes are flashing with a serious gaze that will not admit defeat, and she takes off her blouse and ties it around her waist, and her slightly weak and straight body makes people feel full of vitality at first glance.

Obito is used to seeing Rin's appearance these days, so it's nothing, you must know that when Obito saw this scene for the first time, he was so excited that he almost burst his blood vessels......

Lynn - Whoever dares to hurt you with a finger will be copied all over his house!"

With this kind of consciousness that even if he is desperate, he has to protect the girl in front of him, Obito has been skipping class with Lin almost every day these days. The two of them secretly went to this place that only the two of them knew about to practice, chat, and develop weapons, and they didn't know how happy they were.

Obito also asked for some of the medical ninja tips of the Uchiha family from the elders, the reason is very simple, he wants to study it, but in fact, these precious experiences that cannot be accessed by the outside world are all brought to Rin for Obito.

There are also many ninjas in the Uchiha clan who are engaged in medical careers, and there are about a hundred or so people who work in Konoha Hospital.

Although the elders would have lost their temper if they knew about this, Obito didn't care. Because for the Uchiha clan, the elders are already in their twilight, and as a representative and emerging figure of the Uchiha clan, the value of the Uchiha Obito is far more than any character, not to mention that his talent for ninjutsu is really amazing, and many people have begun to compare him with the rumored god spots of the Uchiha.

"Lynn, do you want to take a break first?" Obito looked at Rin, who was sweating profusely, and his heart twitched with a slight pain.

"It's okay, don't pay too much attention to me. You better focus on your own business! Lin waved her hand and said with a nonchalant smile. No matter when and where, he is always so full of spirit and vitality, and Obito can't help but laugh when he looks at it.

Turning his head, Obito carefully studied this product called "Celestial Strike - Burning Lotus Karma Fire." "High-speed large-area strike weapons. The initial plan was to develop the general shape of the Burning Lotus Karma Fire, and the standard triangular warhead with a three-meter-long body and three launch ports at the tail was used as a reference for later missiles, and the jet energy used was chakra burning.

In the preliminary design, the Burning Lotus Karma Fire has an ultra-long-range strike of up to one thousand meters, the effective control distance is about 300 meters, the explosion radius is based on the steel wire, the explosion charm is hung on the steel wire, when the warhead touches the ground, all the steel wires are ejected in all directions, and then the explosion charm is ignited and directly explodes a vacuum area with a radius of 30 meters.

To be honest, if the Burning Lotus Karma Fire is successfully developed and can be successfully mass-produced...... Hehe.

This will change all the combat methods of the entire ninja world in one fell swoop, and the large caliber and power and the more terrifying explosion damage radius will become the main theme of the whole battle, which is a bit like the invincible battleship of World War II, and all the truth is only within the range of the cannon!

In fact, if you have to say it, the Burning Lotus Karma Fire is actually more similar to the rocket artillery of later generations, hundreds of rockets bombard a certain area like raindrops in an instant, unless all the enemies are Wanhua Mirror Writing Wheel Eyes, and they all turn on Susanoo, in that case, it is indeed useless to attack any P. But if this can't be done, or even if the chakra that is maintained is a little loose, then .......

However, the reality is not that simple, and the humans of this world are not as fragile and powerless as that world.

The presence of ninjutsu and chakra allows the ninjas here to do many unthinkable things, including chakra interference, burying it in the ground before it explodes, or using a wide range of water escape to extinguish the burning explosion charm.

In order to prevent the Burning Lotus Karma Fire from being attacked and stopped before it exploded, Obito added a "Celestial Strike" in front of the name of the Burning Lotus Karma Fire. This means that the attack method of the Burning Lotus Karma Fire will be changed from an ordinary straight line attack to a combat method of falling from a high altitude.

This high-altitude falling strike has more terrifying attack capabilities and excellent concealment, especially for the chaotic battlefield, no one can have the leisure to raise their heads and look up at the sky in the middle of the battle to see if there is any destructive weapon hanging above their heads.

However, if you want to reach this level, the launch height of the Burning Lotus Karma Fire must reach an altitude of 500~800 meters, but if you can, it is best to reach about 1500 meters, so the possibility of being detected is basically zero.

But in this way, the three-meter-long small body obviously cannot meet such a huge power demand, and the weight and the gravitational force of the planet will also be very different, and all data experiments will have to start from scratch.

If the Burning Lotus Karma Fire can achieve the expected ultra-long-range high-altitude strike, then the volume must be at least 15~20 meters, and the energy carried must be x its own gravity x three times the gravitational speed x propulsion CTA/AB54. This means that the weight of the complete body of the Burning Lotus Karma Fire can reach more than 120 tons, and the amount of ammunition carried can raze the core area of the explosion 800 meters to the ground, and the surrounding 2500 meters can become a sea of fire, the maximum rate of fire can break through twice the sound barrier, the longest distance strike distance is 1800 kilometers, and the highest ejection point is basically considered to enter semi-cosmic space at an altitude of 5900 meters.

"Well, it's an intercontinental missile."

After saying that, Obito tore the design sheet to shreds and threw it aside.

"The design must be reconsidered, at least the volume should be compressed within 8~10 meters, and the weight should not exceed 400 catties, but then the range will be sacrificed. Of course, it is also possible to increase the range by reducing the amount of ammunition carried, but in this way, the explosion will not be powerful enough to form a deterrent and achieve the tactical goal of deterring the enemy...... Hmm, tangled. “

"But fortunately, the problem of propulsion fuel has been solved, and after a year of testing, I can preliminarily compress the chakra and seal it inside the solid thruster, and when needed, use my chakra as a medium to instantly open the seal and spray. At the same time, the "whereabouts yin and yang talisman" is written on the part of the warhead, and the medium can be placed at the landing place to form a fixed precision strike, which is a bit similar to the flying thunder god rune of the fourth generation Hokage. “

Obito stared at the white paper on the ground with his eyes attentively, and kept writing and drawing with one hand.

As for how to design tactical weapons that can strike targets from a long distance, they are still deficient in many aspects, especially in terms of range and concealment.

Eh...... It's distressing.

The breeze blows and the grass sways.

The young man sitting on the grass closed his eyes tightly, and a sullen expression appeared between his eyebrows.

Lin leaned sideways, a pair of bright eyes quietly staring at his serious face, and that serious expression was very adult-like.

Over there, Obito was still struggling left and right in distress, his mind full of thoughts and contradictions.

At this moment, Lin suddenly walked over to Obito and sat down.

"Lynn?"

"Yes."

Rin looked at Obito with gentle eyes, with a shallow smile on the corner of her mouth.

"When you are distressed, I can do to be there for you as I am now. So, don't always want to bear all the pain by yourself, because you still have me by your side. “

Lynn ...... Thank you. “

It seemed that the moment Lynn appeared beside her, all the pressure suddenly disappeared. Like the sun, Lynn dispelled the darkness and shadows in her heart, and the thoughts in her head were sorted out at once, and the previous distress no longer seemed to be able to stump her.

If I could, I wish Lynn would always be by my side.

Obito thought so.

However, at this moment, an outsider suddenly broke in.

Obito was the first to spot the outsider, and the moment he saw the other party, Obito's face immediately turned dark.

"You two are staying here, Kawano-sensei is already mad."

Kakashi stepped out of the shadows of the grass, looked at Obito with a cold look, and then cast a gaze at Rin.

"Lynn, you're messing around with this guy too."

"Kakashi ......"

Rin was a little ashamed by Kakashi's staring, blushing and slowly lowering her head.

"Tsk!" Obito's face became gloomy. Sure enough, Rin still has some ...... about Kakashi's little imp Damn, it's a disgusting feeling.

"There's no need to go to that kind of school where children play like home! Both Lynn and I have our own ways of getting stronger. Obito said as he stood up abruptly and stared at Kakashi.

Kakashi snorted coldly.

"It's your business to get stronger, it's also your business to have the Uchiha clan as your backing, and it's also your business to take Rin around with you. However, the school's rule is that students must attend classes within the teacher, and since you are already a ninja cadet, you must obey this rule, and don't always assume that the name of genius allows you to do whatever you want. ”

"Provisions? The school was founded with the long-cherished desire to make children stronger, no matter how they can be, even if they don't attend school classes. Because we didn't go against the will of the college! ”

Obito looked at Kakashi, his eyes in disgust at each other.
