"Psychics!" His hands were sealed, and a large number of unopened weapons suddenly appeared around Kakashi.

"Thunder Escape-Royal Thunder True Sword Flow!" The hands continued to seal, and the weapons, which had begun to fall into the water in response to the Earth's gravity, began to levitate, floating in the air.

"Swordsmanship?" Hitomi was stunned for a moment.

"Be careful! I'm coming! Kakashi reminded and shot the levitating weapons one by one.

"The ninth day of the Qiangua - don't use the hidden dragon, and the sun is down." The chakra in its primitive state was transformed into a strong and powerful force under the action of will, and Hitomi relied on the dynamic vision of his white eyes to block those gold and iron weapons with both hands.

"Be careful! Those weapons are very powerful! They are constantly vibrating! "I felt the high-frequency vibration from the weapon, and Hitomi only felt a little numb in my arm!

"Light Escape-Tiancong Cloud Sword!" The hands were sealed, and a lightsaber appeared on the hands of the future.

After that, wielding a lightsaber, the blood elimination level Chakra fused when he came into contact with the gold and iron weapon.

The Light Escape Chakra is cutting weapons, and the weapons are also using its vibrations to constantly destroy the structure of the Light Escape Chakra.

"Ping!" Hearing only such a voice, the Tiancong Cloud Sword couldn't stop the plural iron swords after all, and it turned into a point of light and disappeared into the hands of the future.

"Light Escape-Eight Mirrors!" Immediately after that, a shield built by six light wheels appeared, and the future moved the light shield to defend itself.

"Water Escape - Water and Sky Attack!" The B-level version of the Water Prison Technique, while defending in the future, used the one-handed seal to use the water escape.

"Sword Skill - Flash!" Quickly and neatly drew his sword and slashed, Kakashi used the self-defense Lan sword to split the water escape, and the future Wei Wei failed to save Zhao.

After that, the anxious battle continued, and the two of them were defeated because of their age and other reasons.

"Captain Kakashi! We threw in the towel! Throwing up his hands in surrender, Hitomi, who was exhausted, spoke.

"Yes! Throw in the towel! Here, the future also raised his hands.

"Throw in the towel? Then this test is almost over here! If you continue to do so, you will have to fight hard. The golden iron weapons flying in mid-air turned into white mist and returned to the other world under Kakashi's control, he said.

"Captain Kakashi, I have a question for you." Here, Hitomi pleaded.

"Ask!" Kakashi said.

"My white eyes can see through the chakra situation in other people's bodies, how did you drive so many weapons and consume very little chakra?" This is the question Hitomi has always wondered.

"Hahahaha, Hitomi! If you are willing to go to school, then you can figure out what power I am using now with the help of the technique. ”

"Kakashi-sensei, too, will be able to clear up your doubts!" Bowing to Kakashi, Hitomi pleaded.

"In modern society, because of the rise of science, ninja is influenced by science and is divided into traditional ninja and scientific ninja."

"What is traditional ninja? The one who owns the chakra, he sees the wind, he sees the thunder and lightning, he sees the flood, he sees the fire, he sees the mudslide, he sees the power of nature. ”

"Then, imitating the power of nature, according to his own imagination, the five escape techniques of wind, thunder, water, fire and earth came into being, and ninjutsu appeared."

"Ninjutsu is still a personal reality in the end, and some ninjutsu require a lot of chakra to be realized. Why? Because to create such a reality, it is necessary to rebel against the existing reality. The larger the scale of the operation, the more chakra is required. ”

"My Imperial Thunder True Sword Flow, if you use the traditional ninja mode to run, tens of seconds is the limit. However, with the scientific ninja to run, I can run for a whole day. Moreover, don't look at the hundreds of weapons, there are already a lot, my current limit is 1,326 swords. Because of this, I was called the Sword of Shinobi by my enemies. ”

"Scientific ninja...... What exactly? Hitomi asked, muttering.

"Scientific ninja is a system of ninbi based on testable explanations and orderly knowledge that predicts the form, organization, etc., of objective things. Take my technique as an example, if you want to reach my level, you must have a deep understanding of electromagnetism, electrodynamics, geomagnetism, and chaos algorithms. ”

"I've never heard of ......" The will of a hundred-year-old man was hidden in his body, and Hitomi's heart gave birth to a desire to seek the truth.

"Kakashi-sensei, I want to study science!" Hitomi said.

"Kakashi-sensei, I want to study science too!" The future is not far behind.

"Both of you have great power, and you have become a shinobi from this. Since it's a shinobi, you have to carry out the task. You don't have a lot of time to study, so you can only find time to study on your own, and the teacher can only answer for you in a limited time. Because, the teacher also has to continue to study, and the time is a little tight. ”

"Thank you, Kakashi-sensei! Your ability to grant me this request is the best response to me. Hitomi said.

"Science is a rigorous and systematic discipline, and without textbooks, your learning will be messy. So, now that we've gotten to know each other, let's go get the textbook first! ”

"Textbooks? How many textbooks are there? Future asked curiously.

"That's a lot, and science also means to learn by subject. Science is divided into mathematics, natural sciences, and social sciences, and these three subjects will continue to be subdivided. In the end, there will be more and more to learn. There are a dozen textbooks to start with, and when you learn them, you can use the money you get from the task to buy higher-level books. ”

"Understood......" both nodded at the same time.

"The core of scientific ninja is science, and the essence of science is just a mode of thinking. If you master this model, you will be able to grasp science, and there is nothing that science cannot solve any problem encountered in reality...... It's here! The three of them talked and came to the most prosperous commercial street in Konoha. At this point, Kakashi brought the two to the Konoha Library.

Konoha Shoku is a large store that sells books, not to mention science books, even small yellow books. It can be said that this is an all-encompassing information base.

"This ...... This ...... All right! "After selecting science textbooks for grades 1 to 6 in the textbook area, the two girls were holding their books and ready to go to the checkout. However, they found a problem, they didn't bring money.

"Kakashi-sensei, ...... the money for the book" Here, looking at Kakashi's actions in paying for them in the future, what does she want to say.

"Count me as the one I lent you, and when you get paid for the task, remember to pay me back!" Kakashi said.

"Thank you!" The two of them spoke in unison, and came to the library with the books in their arms.

After that, putting the book in the storage scroll, Kakashi left with the two of them.
