Night is coming......

Sakuraku set up the washed dishes and chopsticks and walked out of the kitchen.

"Where's Sakura?"

"I'm back."

Ai Ye sat on the bed and took a bite of the apple, and then said to Sakuraku, who was taking off her apron, "What are you going to do next?" ”

"Aren't you going to study chakra?"

Sakuraku said while hanging an apron, "I remember I asked Sakura to give you the book, did you get any results?" ”

"I'll just roll it a few times, but it's a little fruitful."

After Ai Ye casually picked up the chakra refining technique from the bed, he flipped it over and said, "This kind of energy body called chakra is an extremely unreasonable thing in my opinion. ”

"Tell me about it."

"Look here......"

Ai Ye pointed to a passage in the book and said to Sakuraku, who was sitting next to him, "It says that chakra is the product of the 130 trillion cells of the human body, which absorb the body's energy one by one and combine it with the spiritual energy. ”

"Physical energy and mental energy?"

Sakuraki looked at the cover of the book a little confused, and after finding that it was indeed a chakra refining technique, he asked, "Is this ...... Chakra doesn't come from self-free energy in the atmosphere? ”

"At first, I thought it was from free energy."

Ai Ye smashed his mouth and pointed to the book and said: "But now it seems that it is not, the people of this world have not noticed the free energy in the atmosphere at all." ”

"I thought the chakra was some special method of purifying the free energy......

Sakuraku frowned and looked at the description of Chakra in the book, "What does it mean that physical energy is combined with spiritual energy?" ”

"It should be literal."

After Ai Ye laid the book flat on the bed, he took an apple out of his carry-on space and took a bite, "They put their physical energy and spirit ...... It should be the combination of soul energy to produce a special energy body, and then use the chanting method of knotting to release ninjutsu. ”

"But here's the problem."

Ai Ye chewed the apple and swallowed it, then pointed to the body energy in the book and said: "It is impossible to take energy from cells, the body's automatic protection mechanism will reject this behavior, and even self-cutting the heart pulse uses energy from the outside world." ”

"Besides, the energy stored in the cells is the energy necessary for life, and if they can take in this energy, people will be gone."

"So you mean ......"

"What I mean by this is that they don't take in physical energy at all, but they treat it as physical energy."

Ai Ye patted the book and said, "And there is also this spiritual energy, I feel that it should be soul energy." ”

"Not necessarily......"

Although this kind of thing is not Sakuraku's area of expertise, she has a lot of experience, and she has five thousand years of experience, "Maybe it's referring to spiritual power or something, soul energy...... I don't think that's what their level of civilization can relate to. ”

"Mental power......

Ai Ye frowned when she heard this, she thought of Sakura, her mental power was very strong, but except for Sakura, no one else seemed to meet this standard.

"How's Sasuke?"

Sakuraku suddenly opened her mouth to Ai Ye, who was frowning, and asked, "Have you carefully observed Sasuke's mental strength?" ”

Ai Ye was stunned by Sakura's question, "This, it doesn't seem to be true, I just felt it slightly, but the strength of the yellow hedgehog and Brother Xiaoku's mental power is about the same, and it is not as strong as the feeling that Sakura gave me at the beginning." ”

"Remember what Kakashi said about the Blood Inheritance Limit?"

Sakuraku frowned and recalled the details of the original discussion with Sasuke and said, "Sasuke's writing wheel eye seems to be different from Kakashi's. ”

"Not quite the same?"

Ai Ye's eyes flashed with a gleam, and then he asked seriously, "Can you be more specific, Sister Sakuraluo." ”

“…… Sasuke's left eye is a double hook jade, and his right eye is a single hook jade. ”

Sakuraku struggled to recall the difference between Sasuke's Sharingan and Kakashi's Sharingan, "Kakashi's words, only the left eye is a Sharingan, but it's really a three-hooked jade. ”

"I remember Kakashi's full name was Kakashi Hagi, right?"

"yes, what's wrong?"

Ai Ye frowned and said, "If I'm not mistaken, Kakashi still has a scar on his left eye." ”

"That's right......"

After Sakura subconsciously responded, she reacted and said, "What do you mean ......?"

"Kakashi's left eye should be a transplanted ......"

Ai Ye said what Sakuraku wanted to say, and exhaled a long breath, "Little Cool's full name is Sasuke Uchiha, and it seems that this writing wheel eye should be something unique to this Uchiha clan." ”

"And the most important thing is that this bloodline limit of his should be an ability that can evolve."

"Is it a magata-like pattern on the eyes?"

Sakuraku nodded when she heard this, "It's very likely." ”

"It manifests itself in the eyes, then it is likely to be the energy of the brain."

Ai Ye pinched his chin and said, "I will carefully perceive Brother Xiao Ku when we meet tomorrow, I estimate that his mental strength cannot be worse than that of Sakura." ”

"That's a bit off-topic......"

Sakuraku coughed lightly a little embarrassed, after all, the topic was biased by herself.

"I think the specific composition of Chakra should be an unknown energy and soul energy."

Ai Ye didn't care about such a trivial matter, but picked up the topic of chakra again with a serious expression, "Sister Sakura, what do you mean?" ”

"I thought it should be mental power or something."

Sakuraku frowned, remembering Sasuke and Kakashi's chakra again, and then sighed helplessly, "But now it seems that the explanation of soul energy makes a little more sense. ”

"And what is this unknown body energy?"

Ai Ye bit his nails with a little headache, "Then again, how can people in this world directly use soul energy?" It doesn't make sense. ”

"The normal cultivation process is to induce qi into the body, and only after cultivating to a certain realm will they come into contact with the soul thing, and people in the world who do not need the process of inducing qi into the body will generally have an energy processing organ in their body to store and collect energy in the atmosphere."

Sakuraku said while recalling the cultivation systems of other worlds: "A world that does not need to draw qi into the body and has no extra organs in the body is generally a world of science and technology, not by individuals but by groups. ”

"But the cultivation system in this world is not like the four things."

Ai Ye closed his eyes with a headache and rubbed his temples, "There is free energy in their world, but their cultivation does not rely on this free energy, the soul energy that needs a certain realm to be able to touch, but in them it is the foundation of cultivation...... What is this? ”

“…… Otherwise, let's leave it alone, let's treat this thing as a plot need. ”

Sakuraki also felt a little headache, she closed the book on the bed and threw it on the table and said: "Let's treat the people of this world as if they were born immortal, and they also have a deep study of the soul, but no matter what, as long as it is an energy, then he will definitely have a source!" ”

"This body energy can never be the energy in the cells."

Ai Ye said with great certainty: "I dare to swear by my height. ”

"Then there seem to be only two directions that can be investigated at present."

Sakuraki smiled and said, "The free energy in the atmosphere and that thing that seems to be a conceptual derivative." ”

"Anyway, Sakuraku-san......"

Ai Ye seemed to suddenly react to something, she suddenly showed an expression that she was an SB and said, "Why are we so entangled in this chakra, does it have anything to do with our mission goal?" ”

"You have to prepare for doing things with both hands."

Sakuraku patted Ai Ye's head and said helplessly, "What if that thing isn't a concept derivative?" ”

“…… You have a point. ”

Ai Ye nodded in agreement, but he still didn't understand, "But isn't it, what does this have to do with our research on Chakra?" ”

"The specific image of a conceptual derivative is not fixed."

Sakuraku pointed to the chakra extraction on the table and said with a smile, "What if the source of that unknown energy is a conceptual derivative?" There's also free energy, all of which can be conceptual derivatives, and as I said before, we need to be prepared to fight a protracted war. ”

"Makes sense."

Aino nodded, indicating that he agreed with Sakuraku's idea.

"This mission is very special, and we can't rush it."

Sakuraku patted Ai Ye's little head, "The two of us don't have much information now, so I suggest going on a few missions with Kakashi and them first to gather information about this world." ”

"And my intuition tells me that this thing called the Blood Inheritance Limit is worth investigating the two of us."

"You mean those little cool eyes?"

"That's right."

Sakuraku glanced at Ai Ye, who seemed to be thinking about something, and said to herself, "The ability to evolve is generally very promising. ”

“…… It seems that this world is worth studying. ”

Ai Ye raised her head, her eyes were full of curiosity, she was originally a child who was curious about everything, and her most frequent words were 'curiosity is the ladder that leads civilization and life progress'.

After Sakuraku saw that Ai Ye was interested instead of continuing to have a headache, she smiled with satisfaction and said, "This is the Ai Ye I know." ”

"Oops, don't talk about this~~~"

Ai Ye stretched, looked up at the clock and exclaimed, "My mother, it's 11 o'clock!" ”

"Really!"

"Take a shower and go to bed! I have to get up at eight o'clock tomorrow! ”

"Let's wash together, we haven't taken a bath together for a long time."

"I don't want it! Sister Sakuraluo, you always like to use your hands and feet when you take a bath with me! ”

“…… Rejection is invalid! ”

"What are you doing! You let go of me! I don't want to wash with you! I can't wash it! You let go of me! ”

As the bathroom door closed, Ai Ye's screams stopped abruptly, and then the sound came from being a little inappropriate, in order to prevent this book from being harmonized, I won't go into detail here.

All in all, the first night of the two in Konoha ended so happily and fulfillingly......
