For this kind of unplanned supplement, Sakura is naturally happy to see it, but she doesn't care too much.

With Miss Sakura's arrogance, she is confident that she will find a better way to improve herself in the future, so she naturally doesn't look at this little accumulation. But these are at least a few years old, and Miss Sakura's dilemma lies in the present.

Now she has entered a plateau of strength.

To put it bluntly, there is not much room for improvement in physical fitness, and the recently developed ninjutsu can only be regarded as icing on the cake, and it cannot play a core role, and the new ninjutsu is still being studied, so the strength cannot grow as fast as some time ago.

Many of the ninjutsu developed and learned during this time of the Zhongnin Exam have been tested in actual combat, and most of them do not have the potential for further development.

And her two core ninjutsu are basically at the highest level by her. Extremely pure water can only be prepared by effort; water gun technique, from the initial high-pressure water jet, has been upgraded, increasing the pressure, increasing the range, and later adding the change of the nature of the water escape and the change of the nature of the wind escape, into the water escape, the wind blade torrent, in terms of enhancing the lethality, this ninjutsu has gone far enough.

But that doesn't mean that Sakura can lie down on these two ninjutsu and eat the old book with peace of mind.

No matter how strong the ninjutsu is, it is useless if the caster can't do it. Just like a child holding a gun, it looks bluffing, and when fighting to the death, it is not necessarily more dangerous than an adult holding a knife.

For example, what would happen if Sasuke used Rachel and Sakura used the Wind Blade Riptide duel? Sakura had thought about it for a long time.

The water gun technique is a medium-range ninjutsu, and Rachel is a close-range ninjutsu, so of course Sasuke was killed first?

Sakura had been sure of this, but after watching Sasuke's fight against Iara, she gradually had some uneasy thoughts. Ninjas who can fight at extremely high speeds are really very restrained ninjutsu-type ninjas, and even a ninja with absolute defense like Iara, who can be so embarrassed by Sasuke. As long as the enemy's speed exceeds a certain limit, the defense of the technique or the human mind may not be able to keep up with the rhythm of the enemy.

Yes, when the Chunin exam stood in the stands, Sakura could still keep up with Sasuke's speed. But Sasuke's speed still has a lot of room for improvement, and she really doesn't have much talent in terms of speed...... After a year or two, she still dares to be sure that she can keep up with Sasuke?

Will high-speed combat become her Achilles' heel?

After Sasuke opened the Sangotama, she gradually felt struggling during the sparring. Sakura's reaction speed is definitely not slow, but Sasuke is getting faster and faster. It is true that the girl is conceited that she can keep up with the rhythm of the upper ninja level battle now, but in the future, she will almost certainly meet a shadow-level or even super-shadow-level opponent - such as the mysterious Xiao.

She had to be faster, at least reflexes!

Otherwise, just like the enemies of Bo Feng Shuimen back then, when encountering an ultra-high-speed opponent like Shuimen, they will be lost in seconds in the blink of an eye, and no matter how strong their skills are, they will not be able to exert themselves.

However, speed ninjas are almost innate. Dynamic eyesight and reaction speed will quickly reach a limit through acquired exercise, and most ninjas stop at a bit faster, while those who are gifted or plug-ins can do it faster, so they are called speed-based ninjas, such as the fourth generation of Hokage, such as Sasuke who has a writing wheel eye.

And Miss Sakura, unfortunately not.

Actually, there is nothing to regret about it. In comparison with her two teammates, Sakura's difference in strength, stamina, chakra, and blood limit is desperately huge, compared to the fact that she is not a speed ninja.

Of course, more importantly, in Sakura's plan, these gaps are not irreparable. Yes, she is a genius and of course she will not sit back, there are always more ways than problems......

"So that's what you're going to do?" Hinata raised her eyebrows and asked her best friend with a lot of doubt.

In the empty room, in front of the white-eyed girl was a low table covered with a plain white cloth, and there was no extra decoration, and its length and width were just enough to accommodate a person.

And on the table, there is indeed a person lying down.

Lying there was a girl with a hollow eye and a blank face, who was quietly staring at the ceiling, motionless.

What is particularly remarkable is that she is not an inch, and her body is only covered with a layer of white cloth, which can cover her body, revealing only her white and tender limbs.

The pink hair is scattered casually on the table, and the light green eyes have lost their usual agility, but looking at the girl's appearance, there is no doubt that it is Haruno Sakura.

However, Sakura, who was lying on the low table, was indifferent to Hinata's question, her lips were slightly closed, and she didn't even glance at her friends, and just lay quietly and unresponsively, if it weren't for the small ups and downs on her chest, it might have been mistaken for a corpse.

But there was no silence in the room: "Don't worry, Hinata...... This is just a necessary preparation for the development of new techniques. ”

Of course, it wasn't Sakura lying on the table, staring at the ceiling with stunned eyes, pretending to be a corpse.

Hinata raised her head, her slightly blank white eyes and her eyes wandering, looking at the other Sakura Haruno who was standing across the table from her.

The eyes in front of her are smart, and the smiling girl - of course, the more important thing is that the clothes are well worn: light blue short sleeves and lotus lotus-colored pants, obviously the original figure.

"Necessary preparations?"

Hinata raised her eyebrows, but didn't say much, and her gaze moved from the exposed feet of the girl's half-heeled white sandals to her white cheeks, waiting for Sakura's explanation.

She was mysteriously pulled into the laboratory by Sakura, saying that she wanted Hinata to do her an important favor, and then she was busy all morning, and Sakura kept summoning the clone for her to identify...... She wondered what the point of what they were doing.

In fact, Hinata knows what Sakura has been struggling with lately. There are almost no famous speed-type female ninjas in the history of the Hokage world, whether it is reaction or action, it seems that it is common sense that women are naturally slower than men, but on the other hand, Hinata knows Sakura's temper, and her strong self-motivation does not allow her to succumb to this common sense and acquiesce to such a fatal shortcoming.

Perhaps it is a foolish thing to challenge common sense in the eyes of ordinary people...... But Sakura is a man who can break the mold, and Hinata is excited to see what her friend will do.

It's just that what do these things have to do with this strange doppelganger in front of you?

This kind of clone is really weird, it is even more condensed than the shadow clone, and the ice clone formed by the ice escape really looks much more advanced than the ordinary water body......

"Well, let's look at it with the white eyes, Hinata," Sakura let go of Masaki's hands and smiled with satisfaction, "This time the chakra is perfectly controlled, and the effect should be obvious." ”

Hinata glared at Sakura speechlessly, turning her gaze to the ice clone on the table.

She was not in a hurry to open her eyes, but carefully looked at the doppelganger: her eyes were clear and cold under a closer look, with a delicate nose, slightly upturned lips, and almost transparent cheeks.

If it weren't for the daily contact and seeing it with her own eyes, Hinata would have wondered if her friend had asked Tsunade-sama to do some microcosmetic surgery on her.

She still remembered that when she just graduated from ninja school, Sakura was still the little kid with a wide forehead, a big grin, and a facial features that could only be described as delicate, and two years later, she had unconsciously grown into a beautiful girl. Judging from her appearance alone, the jump from 4 points to 7 points is far from being explained by the "Eighteen Changes of the Female University", and the growth rate is even faster than the growth of her strength. Although a rough look, the facial features have not changed much, the eyes are still the same eyes, the nose is still the same nose, only careful observation can find some small changes, such as the bridge of the nose has become a little higher, the chin has been thinner a little, etc., etc., and then the whole person feels a lot more beautiful to others, a little bit of water and moonless taste.

I heard Sakura say that practicing Bing Dun has the effect of improving your physique, but does the so-called improvement of your physique originally also include your appearance? Seriously, Hinata is a little envious: I really want to learn Bing Dun too!

Hinata silently sighed in her heart, her gaze along the girl's slender neck, across the delicate collarbone, and on the slightly scaled, unwielding chest.

Hinata involuntarily straightened up.

"Hinata, open your eyes. Sakura reminded softly.

Hinata does it all. She opened the white of her eyes, and with a penetrating gaze through the thin cloth, over skin, fat, and bone, she saw ...... A beating heart?

Yes, a living, life-like beating heart that pumps blood.

Shocked in his heart, Hinata swept the ice clone all over his body with his white eyes, internal organs, blood vessels, meridians, nerves, etc., all of which were manifested under the glancing of the white eyes, and there were no omissions or mistakes compared to the real human body!

"Oh, that's true...... Exactly simulates a real physical body! "Yes, unlike ordinary clones, this clone that Sakura made with so much effort turned out to be an ice clone that completely simulated the deity and simulated the flesh and blood organs and meridians!

"How's it going?

"Well, not yet...... It's perfect!" Hinata sighed a little, "Amazing, amazing, this kind of doppelganger should be extremely difficult, right? No wonder even you have worked so hard to reproduce the deity completely." What's next? What kind of dangerous experiments are you doing with your doppelganger?"

Sakura nodded, Hinata wasn't stupid, of course she could guess what she wanted to do.

"Yes...... The main thing is to develop a technique, if successful, it can improve a lot of reaction speed! It is to use ninjutsu to strengthen the nervous system, just like chakra strengthens muscle strength, but there will be a lot of trouble in the details. And when it comes to nerves, it's too dangerous to test yourself directly, and ......" Sakura paused meaningfully.

(How can anyone still remember the black history of this book, forget it.)
