"How did you come to this era? Can you tell me this?"
"There is nothing that cannot be said. Sasuke Uchiha and Boruto Uzumaki were chasing Ōtsutsuki. He turned on the magic weapon plow that can travel through time, and I followed him in."
"Sasuke-kun..."
Orochimaru pondered for a moment, then looked up at Shirozumi, "For example, you returned to this era because of Sasuke. If you kill Sasuke, what will be the result?"
"Sasuke in the future is dead, so you cannot achieve the cause of "traveling through time and space with Sasuke", and there is no effect of "killing Sasuke". Since you have not "killed Sasuke", then you have satisfied the condition of "traveling through time and space with Sasuke"... This forms an endless loop paradox."
Orochimaru spoke very seriously, but Shirozumi listened with all the confusion.
Sasuke Paradox, right?
Sure enough, the few words before could not immediately change Orochimaru's obsession with Sasuke.
"Then why do we have to kill Sasuke? If we don't kill Sasuke, wouldn't everything be fine?"
Hanabi raised his little hand as if he were speaking in class.
Teacher Orochimaru also responded very "kindly": "This is just an example. Not to mention killing Sasuke, as long as some slight changes are made to Past, drastic changes will occur in the future."
Having said this, Orochimaru looked at Shirozumi: "Shirozumi, your goal is to change the future and deal with that "Ōtsutsuki", right? Then, according to this logic, your method is inherently contradictory.
When you return to Past, Past becomes your future, and the future becomes your Past."
After Orochimaru finished speaking, he just waited for Shirozumi's answer.
Shirozumi didn't seem to be deceiving, but reason and logic had to make him doubt it.
"Actually, the paradox you mentioned is easy to solve. I have two conclusions that have been proven to be wrong, which can deal with the paradox."
"Oh?"
Orochimaru was a little surprised.
"The first theory is parallel world. The so-called return to Past is just a parallel world that is almost the same as the original world Past.
Any actions taken in this world will not affect the original world, so naturally no paradox will occur."
"Hiss."
Orochimaru After hearing this theory, he frowned slightly and took a breath.
It seems that this is indeed the case.
"When you say this theory is wrong, you mean..."
Orochimaru asked.
"Land of Wind There is a place called Rōran in the desert. Minato Namikaze once experienced visitors from abnormal time and space there. The sealed memory did not affect the future, but it still left evidence of the time loop."
Shirozumi said, whether it is the Chakra Blade from the future in "The Lost Tower",
Or after Boruto Sasuke returned to Past, Boruto said "Thunder Car" and asked Denki's father to create a thunder car in the future. This reflects the time loop and there is no parallel world - at least there is no possibility of a parallel world that is equivalent to the main world.
Like Limited Tsukuyomi, this artificially created low-level Genjutsu World. After the Sakura inside comes to the real world, it will become mentally unstable and lose its memory because it comes from the low-level world.
"I see, what about the second theory?"
Orochimaru nodded, agreeing with Shirozumi's statement.
There is no doubt about what Shirozumi said about Rōran and Orochimaru.
This kind of thing is too easy to verify, and deception is completely meaningless.
In fact, the emergence of this theory alone has already overturned Orochimaru's previous doubts. However, due to his thirst for knowledge, Orochimaru still wants to know the second theory.
"The second one is actually a conjecture."
"If all matter and energy have the smallest unit, then it means that all movements and changes occur in leaps and bounds, rather than continuously.
Just like a movie, it is essentially a continuous playback of countless pictures. Returning to Past is like modifying one of the pictures."
This theory can also solve the "Sasuke paradox", but it can also be refuted by the "Rōran" example Shirozumi just gave.
"My head feels so itchy, I feel like I'm going to grow a brain."
Karin scratched his head and felt a little headache.
It seemed like she was the only one present who didn't understand a word.
Karin's current reaction is like scolding Naruto and Shadow Clone Jutsu as a rabble, while Naruto is confused about what rabble means.
I suffered the loss of being uneducated.
"Having said so much, you only proved that Orochimaru's idea is wrong, but you still failed to explain the logical problem. How can you change the future?"
Tsunade spoke.
"I don't know either, but I'm sure I can do it."
Shirozumi stood up slowly and patted his pants.
Shirozumi has never substituted the "scientific theories" of the original world into this world, only the corresponding way of thinking.
The basic physical laws of each universe are different, and that is perfectly normal.
One universe can only develop technology, while another universe may be able to cultivate immortality.
Ninja World possesses Chakra, possesses Natural Energy, and magical powers, which are obviously different from the original world.
Substituting it directly is tantamount to carving a boat and seeking a sword.
And there are very few people in the entire Shinobi World who truly understand the nature of this world, or even just want to understand it.
So during the Boruto period, Shirozumi will find Kabuto Yakushi, now let's find Orochimaru.
"Can you help me? I'll prove it to you."
Shirozumi walked up to Tsunade.
"Oh? How can I help?"
Tsunade The corner of his mouth raised slightly.
"Stand behind me and attack me at any time."
Shirozumi found a seat and turned his back.
"Okay, this is what you asked for!"
As soon as Shirozumi was mentioned, Tsunade's eyes lit up and he stood up eagerly.
"Tsunade, wait!"
Orochimaru saw Tsunade striding behind Shirozumi, about to start fighting, and hurriedly shouted to stop.
"Shirozumi-kun, please tell us the principle of the proof first. If you explain it later, you may miss many details."
Orochimaru wiped the cold sweat from his forehead.
I wonder if Shirozumi and Tsunade have any personal grudge?
Why does Tsunade want to beat Shirozumi so much?
"Okay."
"I have an ability, Time Deletion, which allows me to see images of the future for a period of time.
Under normal circumstances, after I see the future scene, the only way I can change my destiny is to use Time Deletion to delete the things that happen in the future that are not good for me, thereby changing the outcome.
But in fact, this is not the case.
I can easily change the facts that have already happened, and I can continue without following the future direction I see in my ability..."
"Got it."
Boom--
As soon as Shirozumi finished speaking, Tsunade behind him bent his waist and charged up a punch to hit Shirozumi's lower back.
However...
"Huh?"
Tsunade frowned as he looked at the forest in front of him that was shattered by her fist, then looked back at Shirozumi who was intact behind him.
