My eyes know the ninja world

Chapter 141 A Thousand-Handed Death
Northern Lugu grabbed a Frost sword and threw it back.

Dorose caught it firmly and put on a defensive posture.

Bang bang bang!
Those frost-shaped weapons are as fast as Namikaze Minato's shuriken shadow clone technique, passing afterimages in the air.

Lily of the Valley Chunyu mobilized the chakra in her body, and her mental energy and physical energy all reached their peak.

Under the blessing of the spirit body connection of the Yin-Yang escape technique version, she did not dodge or dodge, holding the dagger in her hand and punching at high speed.

boom!boom!boom!
The seemingly pink and small fist can easily tear the hard and heavy ice-shaped weapon.

The ice shards formed by the shattered frost were all engulfed by the violent fist wind and flew towards the direction of the furnace drum in the north.

After blocking the next wave of attacks, she naturally threw the dagger in her hand diagonally backward.

Zheng!
Doroser couldn't catch the speed of the dagger, so he could only subconsciously raise his sword in front of him.

The Frost long sword shattered instantly, but the dagger was also thrown out, spinning and landing on the ground on one side.

Lily of the valley rained a little on the ground, turning into an almost uncapturable afterimage.

The next moment, she had already bypassed all the blockages of frost weapons, and came to the front of the North Hearth Drum.

Throwing punches at high speed and continuously!
The frost armor on the surface of Northern Furnace's body is constantly shattering and condensing.His body trembled from the huge force, but his upper body remained upright.

Lily of the Valley Chunyu seemed to be having a good time playing, so she made the sound of Ola Ola Ola Ola.

Northern Furnace took a deep breath, his muscles hardened, and the frost armor on his hands became thicker, forming a pair of gloves with icicles.

He unexpectedly regained his breath, and instead raised his fist to collide with Linglan Chunyu.

Bang bang bang!
Linglan Chunyu could shatter his gloves with just one blow, and those icicles that looked terrifying were like popsicles, they would collapse at the touch of a finger.

On the contrary, the arms and bones of Beilugu are extremely tough, and they are alive and well after being pulled by Euler for more than ten seconds.

After punching for a while, after the novelty wore off, Linglan Chunyu felt a little bored.

She instantly appeared near the dagger with the Flying Thunder God Technique and picked it up.

Before Bei Fugu could react, he smashed the frost armor on his back with a fist with his left hand, and then ruthlessly plunged the dagger into his body with his right hand.

After that, she pulled out the dagger again, and appeared beside Doroseph at an incredible speed.

laugh--

Like cutting tofu, she cut off Doroser's sword-holding right arm.

It seemed that it was still a continuous move, she slightly exerted force to the right, and cut a deep wound in the shape of a line on Dorose's abdomen.

"You see, I said there is a price for everything."

As Linglan Chunyu said this, she stomped the right arm on the ground to pieces.

"You..." Dorose seemed to be wearing a mask of pain, trying to say something with difficulty, but couldn't speak.

"Forget it, I'm going to be kind today, so let's keep you from killing. Being able to analyze so many things in a short period of time may be useful in organization." She said kindly.

"Put him on your back and keep going."

So the three set foot on the road again.

……

Unnamed Research Institute.

Ninomiya Qiuxue and Senshou Fei are discussing an academic issue.

This question is extended from space-time ninjutsu. Simply put, it is: whether time-space ninjutsu follows the principle of relativity.

Qianshou Feijian shook his head: "Time and space ninjutsu is to transfer from one place to another in an instant. There is no intermediate process at all, and there is no prerequisite for calculating the speed. To be precise, the speed should be infinite."

Ninomiya Qiuyuki glanced at the Michelson interferometer in front of him, and said with a smile: "Then how to explain this phenomenon we observed? There is no absolute frame of reference, and Maxwell's equations hold true for all frames of reference."

"In this way, either Maxwell's equations are wrong, or the principle of relativity is wrong. But since space-time ninjutsu already exists, it itself proves that there is no upper limit to speed."

Qiu Xue shook her head.

"You are still bound by common sense. Because the space-time ninjutsu seems to reach the destination in an instant, it feels that its speed is infinite. Is this true? It must be strictly measured to find out."

Qianshou Feijian argued: "Didn't you say that you have already measured the principle of relativity of mass? The faster an object moves, the greater its mass. If the time-space ninjutsu does not reach infinity, it is even less than the speed of light. In that At this speed, my quality will inevitably increase, and my total energy will also skyrocket...it does not conform to the principle of energy conservation at all."

Qiu Xue said with a smile: "It seems that you already have a strong scientific literacy. But...in fact, it is not absolutely impossible to explain."

Sensing the perplexed eyes of Qianshouban, Qiu Xue explained: "In addition to time-space ninjutsu like Flying Thunder God, we also have time-space ninjutsu such as teleportation or reverse spiritism."

"If the two parties cooperate tacitly, use psychic and reverse psychic techniques, and use the psychic world as a springboard to achieve an effect similar to the technique of Flying Thunder God. Do you think it violates the principle of relativity?"

Qian Shou Fei thought for a moment, then shook his head and said, "It's not in the same time and space at all, so how do you calculate the speed?"

Qiu Xue nodded in affirmation: "Also, I told you about Obito's kaleidoscope ability before. You said that he entered the space of divine power through his ability, and then came out of the space of divine power, and the effect of long-distance teleportation achieved is very similar to that of spiritism. similar?"

Qianshou Feijian agreed.

"Actually, the principle of relativity does not mean that the speed cannot exceed the speed of light. To be precise, it means that the speed of information transmission cannot exceed the speed of light. You should know that what happens in two places on the ground that are quite far apart can be viewed from a high-speed moving spaceship. From the perspective of the ground, the order of the two may be inconsistent."

"For example, A was killed suddenly in the Land of Fire during Senjujuma, and B was assassinated by a daimyo from the Land of Thunder... If the time intervals between them are very close, and the distance between the two places is very far, then who will come first? Who comes last can be disputed."

"However... If A is a sudden death in the Thousand Hands, and B is someone pretending to be a Thousand Hands. The two events have a causal logic relationship. The people in the Akatsuki organization know that you are dead, at least Knowing that you are rumored to be dead, I deliberately pretended to be you to deceive Konoha."

"If a person in a spaceship looks at the earth and finds that B happened first and A happened later, wouldn't that be impossible? There is no sudden death in Qianshoubeijian, why would the Akatsuki organization pretend to be Qianshoubeijian?"

Qianshou Feijian nodded again and again.

It was Qiu Xue's sudden death one bite at a time, which made him feel a little uncomfortable...

"Fortunately, if you use the formula to calculate it, you will find that it is actually impossible. If I first observe A's sudden death in the Thousand Hands Room on the ground, and then observe someone in B's disguise as a Thousand Hands Room. From a purely mathematical point of view Let's think about it."

"With a simple calculation, you will find that in essence, if you want to observe that B happens before A, and then pretends to die suddenly, you need a prerequisite. The fact that B is disguised, and the place where it happens is far from the sudden death of A, is greater than or equal to the speed of light and the time interval of ground observations..."

When Qiu Xue said that, of course Qian Shou Feijian could understand.

However, he considered that there are readers... so he explained it in his heart.

It is very convenient to understand in this way: after the sudden death event of A, immediately there are photons carrying information about the sudden death in Qianshoubeijian spreading out.Once the photon is touched at the place where something happened, it can no longer happen before A's sudden death.

The Uchiha Madara who was peeping at that place "saw" Senshou Himama died, and then discovered that there were signs of awakening in the eyes of reincarnation-even if there is no absolute causal relationship, the sequence of things cannot be reversed.

Qiu Xue continued: "This is something called a light cone, and the normal causal relationship can only be maintained if it is not broken through. If your space-time ninjutsu can move instantly and spread information at a speed exceeding the speed of light, then Everything is messed up.”

"Suppose that the moment you died suddenly, you suddenly came back to life. You immediately rushed to Muye Village and said to the villagers, 'I died suddenly, I died suddenly'... At this time, what they did was known to thousands of people. What you did when you died suddenly—assuming you are a high-ranking Hokage, they can even believe you when you say you have died suddenly."

Qian Shou Fei's face was paralyzed and he said: "Can you stop dying suddenly?"

Qiu Xue said with a smile: "It doesn't matter if you die violently or not. It doesn't matter if you die suddenly in Qianshou's door. This is an example. You don't need to think about its specific meaning. But the key point is that what they did is that they already know Qianshou Those who died suddenly, such as preparing for a memorial ceremony."

"If you look at it from a special frame of reference, a spaceship moving at high speed, you will find out why the people in Muye Village suddenly started to wear mourning clothes, and they are still alive and well... oh, they are really dead Oh, the people in Muye Village are really good at pinching and counting..."

The black line on the face between the thousand hands.

Qiu Xue said with a smile: "You may misunderstand that this is a personal attack, but this is the truth."

Millennium Feijian took a deep breath, nodded and said: "I probably understand your starting point. If the transmission of information exceeds the speed of light, then the causal chain will be destroyed... So space-time ninjutsu cannot exceed the speed of light. But... you have to What theory is proposed to explain the speed of space-time ninjutsu?"

Qiu Xue shook her head: "It's not urgent, I suddenly have something to do now. In theory, it's okay to wait until the speed of space-time ninjutsu is measured."

"what's up?"

"I have a courier arrived and I need to pick it up." He smiled and stood up.

　You also know that there is a theory of relativity in Naruto, which is the Chunin exam question asking if you can explain it.There is no detailed test for that question. If you dig deeper, there are many test points.At least the relationship between space-time ninjutsu and the theory of relativity is a big test point.After reading, remember to focus~
