A few days later.

"Fifty-eighth. ”

Slug said calmly.

Through its translucent body, it can be seen that there is a girl sitting in the slug's body, and a huge amount of chakra breath fluctuates violently on the girl's body, sometimes steady, sometimes undulating like a stormy wave. The girl's appearance is also changing: suddenly maintaining her human appearance, and suddenly her limbs soften, showing signs of transformation into a slug.

It was Sakura Haruno who was practicing immortal arts.

And at the same time as the slug said this number, the chakra fluctuations on Haruno Sakura's body became more and more violent, and finally broke through a certain boundary and broke the embankment cast by Haruno Sakura's spirit like a flood. A massive amount of natural energy lost control, frantically pouring into the girl's body, eroding her **, and in an instant, Sakura's limbs quickly softened, and her skin faintly became transparent!

Seeing that the owner of the contract, Sakura Haruno, was in danger, the little slug was still very calm, and spit her out unhurriedly, and easily sucked away the natural energy raging in her body, resolving the danger.

Haruno Sakura landed in front of the little slug with a "snap", her face turned blue, and she gasped for breath.

The natural energy quickly dissipated from her, and when it fell, it was still a mass of jelly-like soft flesh, and it naturally returned to the green fingers and white slender feet.

"This time you held on for 3 minutes and 2 seconds before you lost control, which is a full two minutes longer than the last time. There is progress!" The slug glanced at the naked girl in front of him, and said lightly, "If you continue to cultivate at this level of progress, try dozens of more times, and you will be able to maintain the Immortal Chakra steadily!"

"It's good that it goes so well. Sakura Haruno said weakly as she breathed the air greedily.

She struggled to her feet, spread her hands and said, "I know all the techniques of manipulating natural energy, and I will not make common mistakes again, and it is unlikely that I will make such rapid progress." The rest can only rely on water grinding kung fu, and use a lot of practice to pile up the experience of manipulating natural energy, and slowly improve. ”

Sakura Haruno is actually quite close to success. Judging from the cultivation progress of the Manipulating Immortal Chakra, she had already mastered ninety percent of the content, but the remaining one percent was the most difficult part, and the time required to complete it was much more than the time it had taken before.

The cultivation of immortal arts is like maintaining the balance of the scales, one side of the balance is placed with the weight of natural energy, and the other side is the physical and spiritual energy, the two are precisely equal, the balance can be balanced, otherwise, the slightest deviation, the balance will tip instantly. The problem is that on this side of the natural energy, the weight is constantly fluctuating and increasing, so the other side must also constantly add more energy accurately, and this is where the real difficulty of cultivation lies.

Slug smiled, "Then let's take a rest first, Sakura-sama Haruno." ”

"It seems that you have reached the limit today, so don't be reluctant to cultivate anymore, eat something. ”

The girl nodded wearily.

For this kind of experiential cultivation, Sakura Haruno knew that the effect of the shadow clone cultivation method would be very good, and the efficiency could be increased exponentially, but she didn't need it—just cultivating immortal arts with her body was tiring enough. Sakura Haruno also wants to be as energetic as Naruto and cultivate forever, but it's a pity that she is just a mortal, and she barely opens a multi-soul hanging, and she is only a little stronger than ordinary people, and she is far from that kind of guy who openly opens the hanging.

Moreover, Naruto's tenacious personality relies more on intuition than thinking twice before acting, which will also greatly reduce the mental pressure on the deity of the shadow clone. With Sakura Haruno's delicate mind and the temperament that likes to expand her thinking, she can't learn Naruto's way of acting.

"Alas. Sakura Haruno sighed subtly.

The characteristic of mortals is that they get tired easily. The cultivation of immortal arts, for her physical exertion is not too big, but after repeated attempts, and then repeatedly failing, the frustration that constantly breeds in her heart and the nausea every time she is spit out by the slug are mixed together, and the number of times is too much, even if she is as tough as Haruno Sakura, she feels mentally and physically exhausted, and subconsciously resists the cultivation.

Sure enough, she's not Superman yet.

Slug felt a little confused by the girl's sudden lamentation, but the amount of cultivation far beyond ordinary people made her a little unbearable, and Sakura didn't explain much, and walked to the side on her own, standing on the edge of the platform she was on, looking out.

The majestic view of the Wet Bone Forest can be seen at a glance.

The magnificent scene made her tense heartstrings relax at once.

The platform on which Haruno Sakura and Slug stood was actually a huge branch of an ancient tree in the Wet Bone Forest, and a flat platform was created at the fork, about the size of an ordinary house in Konoha Village, and the location was extremely high, and it was used by them as a place for Haruno Sakura to practice and live during this time.

At the foot of the feet is the steaming wet bone forest, countless ancient trees with white and slender trunks, like bones standing on the blue water of the lake, curling white mist rising from the surface of the lake, lingering at the bottom of the bone forest. A few idle white clouds float high or low, far or near, in the air, floating close to the Haruno cherry blossoms.

If it weren't for the fact that the lake under your feet is a strong acid that will leave no bones when it falls, if it weren't for the fact that the white mist is actually a corrosive acid mist that is extremely poisonous, this grand scene can probably be called a fairyland on earth.

From such a tall ancient tree, even the giant slug immortal has shrunk a lot in his field of vision, so that he can easily see the whole picture of the immortal, and the giant creature that is two or three thousand meters long is swimming faintly in the sour lake at his feet.

A cool breeze blew gently, naughtily picking up the soft hair on the girl's forehead, brushing her body affectionately, bringing a trace of coolness to this hot July, so uncomfortable, Haruno Sakura only felt full of tiredness, and most of it disappeared at once. She unfolded the scroll that carried her belongings, took out the food, and unnoticed Naruto's letter as well.

- Not the one sent from the Star Ninja Village earlier, but a letter sent by Naruto after learning that Sakura was going to the Wet Bone Forest to practice immortal arts.

"Come on, Sakura-chan, I've lent you my vitality, let's work hard!" she saw when she picked up the letter. Sakura Haruno could fully imagine Naruto's passionate expression on his face when he wrote these words, as if he was right in front of him.

Heh, Naruto.

"I'm not trying to cultivate the Yuan Qi Bomb. Sakura Haruno complained secretly, but a lingering smile appeared on her face unconsciously. When she took out the tableware and prepared to eat, the words "Haruno Sakura's class will never be disbanded" on the cup were facing her, and Haruno Sakura inexplicably remembered those people in the village and those smiles.

"Tsk. Sakura Haruno felt like she had really been rejuvenated, and she suddenly stopped getting tired. Just like the arduous training she carried out in the land of snow, every time she couldn't hold on, she remembered the beautiful things in her life in this life, and Haruno Sakura always regained her energy.

"Slug, let's do it again after dinner!"

"One hundred and ninety-fifth time. ”

The slug conscientiously counted the number of times he cultivated immortal arts.

It's been a week later...

After a large amount or even an excessive amount of cultivation, Haruno Sakura's immortal chakra has been mastered to near perfection, and the first stage of cultivation is slowly approaching the end. In the previous cultivation, Haruno Sakura had been able to hold on for more than an hour, and now it was the last level: here the slug would infuse a huge amount of natural energy into Haruno Sakura's body in a very short period of time, and the unruly energy instantly broke the balance that the girl had worked so hard to maintain, causing her cultivation to fail - in fact, she had already failed a lot.

This is an extremely dangerous process, the massive amount of natural energy has a very strong corrosive effect, and if you are not careful, even the slugs may not be saved!

On the contrary, if this difficulty can be overcome and this natural energy can be tamed, Haruno Sakura's immortal chakra manipulation can be declared passing.

At the same time as the slug's voice fell, the immortal chakra fluctuations on Haruno Sakura's body began to become violent.

I wrote it until two o'clock last night, and I really couldn't write, and I broke off. Today's three watches, this is the first watch.
