Naruto's water escape is the strongest

Chapter 129 is easy to understand as long as you imagine it

"Hmph~ So boring..."

Thinking of the next step of painting tens of thousands of Yin Seal spells on her body, Sakura guessed that this must be a large-scale project that was time-consuming, boring and boring.

It suddenly became boring.

Everything in imagination is very beautiful, but the reality is that those stage three ninjutsu are all far away. They are still in stage one and stage two, and there is no shadow of the next stage of the Yin seal.

She is still far away from Sakura in that form!

She changed her position from the salted fish form spread out on the table, lying on the back of the chair as if her spine had been removed. She kicked her feet back and the chair began to shake.

Using a four-legged high-backed chair as a hammock to rock back and forth, using only its rear two legs as a point of support, this kind of action that can cause you to lose your balance if you don't pay attention requires very high physical skills to complete, and now she I can already make it easily.

Putting her hands behind her head, raising her feet high and dangling her calves casually, Sakura stared at the ceiling and began to feel dazed.

Boring ninjutsu always makes people lose motivation to work.

The girl's diligence in ninjutsu is out of interest. When encountering this kind of ninjutsu, she can't help but procrastinate. She just wants to find an excuse to avoid facing the boring reality.

"Damn it~ There's nothing else that needs to be done right now except this!"

She thought hard for a while and then said through gritted teeth.

After spending a few minutes, I finally defeated my laziness and buried myself in the papers.

I forced myself to work all morning, and at noon I went out to look for food with my heavy head shaking.

On Konoha Street.

"Hmm~" Sakura looked at the sun and saw that the time was not going up or down, which made her feel a little uncomfortable.

The ramen she had just eaten had been digested. She walked on the street and touched her belly. It was completely flat. She felt breathless and felt sleepy immediately.

"Should we go back and take a nap, or should we go find the master?" she murmured to herself.

The midday sun was so bright that it heated the back of her neck, and the weather was so lazy that she couldn't get excited.

Haha~~ She yawned and felt a little lazy all over.

Well...it's September disease!

——Although it’s almost October.

But in the end, his feet brought him to the Hokage's office.

Sakura walked in without knocking and saw Tsunade's sleeping face:

Lord Hokage lay on his desk, sleeping soundly with his right arm as white as jade as his pillow.

Looking at it from Sakura's point of view, a large area of ​​spring scenery can be seen at a glance: Peeking down from the open collar, the plump softness bulges like a hill, and two pieces of jade-like white meat are squeezed into a deep ravine, as white and tender as a crisp. There seems to be a subtle fragrance coming from the skin.It pressed against the table, fluctuating with the breath, changing shape like a water ball.

She took a step closer and Tsunade woke up hazily when she heard a sound.

"Sakura, it's you..." the Fifth Hokage murmured with sleepy eyes, "What do you want from me?"

She asked while rubbing her eyes, with a trace of glistening saliva remaining on her plump crimson lips.

Sakura blinked--didn't you ask me to come here?

The confused look in the girl's eyes reminded Tsunade, who straightened out her messed up hair and clothes, and finally regained consciousness.

"Oh, by the way, that's it." She slapped her forehead and said suddenly.

So he took out a scroll from the drawer at his feet. It was the scroll of the ninjutsu development progress report handed over by Sakura. There were two majestic characters written on it -

Sakura rushes.

"Your scroll." She handed the scroll back to the girl, who opened it and saw that it was already full of comments.

"I've written down all the things that I think are inappropriate and need improvement. You can take it back and read it yourself. If you don't understand anything, come back to me."

Tsunade patted the chair in front of her desk, motioned for Sakura to sit over, and then said: "I took a look, and the first stage of your Sakura Chong is basically completed. Go back and overcome those few small problems." But in the second phase of development, you have never been able to achieve the desired results. In my opinion, your ninjutsu should have missed an important point."

She picked up the paper and pen and drew a few strokes on the paper.

A long pillar is drawn, with a raised crown at the top.

"Look, these are two neuron cells, and this is the axon of the first cell." Tsunade pointed at the long pillar with her pen and explained to Sakura, "In fact, you only considered the nerve impulse in one cell before. The issue of conduction on nerve fibers has not been considered. The transmission of nerve impulses from one cell to another actually consumes a considerable amount of time."

Sakura saw a long pillar with a rounded tip at the edge of another cell.

Well...she understood.That long pillar is the axon of a nerve cell.

"This knowledge should have been explained to you in detail at the next stage. However, since you have already developed this ninjutsu, I will teach you it in advance."

"Come closer and look here." Sakura leaned over and saw Tsunade quickly completing the simple drawing and drawing a complex pattern in a few strokes.

Draw another nerve cell on top, so that the tip of the axon touches the edge of the second nerve cell.

Tsunade pointed to the round crown on top of the long pillar.

"The terminal end of the axon of this neuron cell is enlarged and cup-shaped, called a 'synaptosome', and is in contact with the cell body or process of another neuron cell after the synapse. This is the structure of the contact part of the two nerve cells. picture."

Very nice, long cylinder, cup-shaped crest, synaptosomes.Sakura stared at the diagram drawn by Tsunade and silently recited these words, feeling herself want to laugh uncontrollably.

"After the nerve impulse is transmitted to the synaptosome, the presynaptic membrane releases neurotransmitters - mainly acetylcholine - across the synaptic cleft and ejected onto the postsynaptic membrane of the next cell, stimulating it to produce neural excitation. This is the process of transmitting nerve signals between two cells." Tsunade pointed to various parts on the diagram with a pencil and explained to Sakura.

The synaptosome sprayed the medium onto the other side's membrane. Sakura nodded repeatedly as she listened to Tsunade's explanation.this process!It’s really not difficult to understand!

"Because the process is complicated and chemical media are used to conduct signals, the efficiency of this process is very low. Therefore, if your development in phase two is just to speed up the conduction of nerve signals in the fibers without considering this In the process, of course it will soon reach its limit and the reaction speed cannot be further improved!"

"Hmm..." Sakura took the paper and pen and pondered for a while looking at the sketch above.

He carefully digested what Tsunade said.Apart from all the professional jargon, what Tsunade said was actually very simple.

All it takes is some imagination.

She had a pretty smart mind and quickly sorted out her thoughts.

Nerve signals are transmitted from one end of one cell to that end, and then to another cell. These are two processes.The former uses electrical signal transmission, while the latter relies on chemical signal transmission.

In other words, it is not enough for the signal light to be transmitted quickly within the long cylinder. The process of medium injection to the rear film must be accelerated.

Sakura's previous stage two only considered the process of accelerating the first electrical conduction, but did not consider the process of chemical transmission.The reaction time occupied by the latter is actually quite long.

"I see...I understand." Sakura said as she put away the tissue paper.

There is no ambiguity at all.

Her medical level is really like a half-bucket of water - but it has been greatly improved compared to the previous state of an empty bucket with no water, and this half-baked knowledge is still the medical treatment she has been given to her by Tsunade during this period. The results learned from books.

Since it is chewing books, it must be rote memorization without asking for a deeper understanding. Therefore, the previous development of Yingchong-Phase [-] relied more on her superb chakra manipulation ability to complete it, but after Phase [-], she only knew a little bit about it. Knowledge has become a major obstacle to the development of ninjutsu.

Sakura now regrets why she didn't study medicine in her last life. It's really painful to chew on these big guys, and the progress is slow.She clearly knew that she lacked knowledge about the human body, but it was wishful thinking to learn all this knowledge in a short time, so she could only ask Tsunade questions while developing.

Tsunade then asked: "So have you figured out how to deal with this problem?"

Sakura shook her head, how could she have a good idea right away?

"I have to go back and think about it again." The girl said to Tsunade honestly.

"Then I suggest you continue to use the previous method, that method has great potential!"

The method Sakura used before was simply to use chakra to create a new ion channel in the nerve fiber to replace the original inefficient sodium and potassium channel. The nerve signal is conducted in the new chakra ion channel, and its speed will be much faster. Signaling speed is higher than that of normal cells.

She calls it the electrification of motor nerves.

Tsunade's intention is to extend this approach to the chemical transmission process between the presynaptic membrane and the postsynaptic membrane, so that the nerve signals can be changed from slow chemical transmission to efficient electrical transmission. This is indeed bold and tempting. idea.

But there are still a lot of problems that need to be solved as to how to do this.

Sakura was convinced that this was a good idea, and couldn't help but ponder it in her mind.

"Ahem, don't worry, Sakura, you can go back and think about it later," Tsunade coughed twice, interrupting Sakura's contemplation, and continued, "I have one more thing here..."

She pulled out two pieces of paper from the pile of documents and handed them to Haruno Sakura.

"I want you to join ANBU."
